If you just so happened to be in whiff range of the comet, you would be treated to a fantastic “perfume” (the ESA’s words, not mine) that smells like a combination of rotten eggs and cat (or horse) urine, with a soupçon of stale alcohol and suffocating formaldehyde thrown in for good measure. In the words of the ESA, “If you could smell the comet, you would probably wish that you hadn’t.” Curiously, this is the first time that humanity has ever smelt a comet. We’ve taken photos of the comet from a long way away, and used spectroscopy to get a rough idea of the comet’s makeup, but to get a good idea of the actual chemical makeup of the comet — and the volatile odorants that are released as it nears the Sun’s melting warmth — you have to get close enough that you can actually take a good ol’ whiff. The European Space Agency’s Rosetta, which has been chasing comet 67P around the Solar System for 10 years, is the first time that humanity has ever orbited a comet — and thus the first time we’ve ever been close enough to perform such detailed analysis. Comet 67P, photographed by Rosetta. You can see why the irregularly shaped comet is sometimes called ‘the rubber duck’. From a distance of around 10 kilometers (6 miles), Rosetta used its ROSINA sensor to analyze the gases currently emanating from comet 67P (or 67P/Churyumov-Gerasimenko to give its full name). Along with water and carbon dioxide — the primary ingredients of most comets — Rosetta detected significant quantities of hydrogen sulfide (rotten eggs), ammonia (cat or horse urine), and formaldehyde (just straight up nasty). There’s also some methanol in there (i.e. alcohol), and the “vinegar-like” smell of sulfur dioxide. All in all, if you happened to be walking on the surface of comet 67P, it would probably smell pretty darn nasty. (But you’d probably be wearing a sealed and pressurized spacesuit, so…) These findings are exciting for a couple reasons. First, 67P is still quite far away from the Sun, and it should still be just a big frozen ball of ice, carbon dioxide, and rock — at this distance, the ESA didn’t expect to detect so many smelly volatile molecules (and indeed, we’re now wondering just how pungent the comet will get as it starts melting and sloughing its outer layers in earnest). Second, the data being gathered by Rosetta is brand new; it’s telling us stuff about comets that we simply didn’t know before. The physical and chemical makeup of comets is of particular interest because they give us fundamental insight into what the Solar System was like billions of years ago, when it was just a nebula of gas and dust. By understanding the structure and formation of comets, we get ever closer to understanding how we — how life itself — came to be.

The comet made its closest approach to Earth passing just over 70 million kilometres away last week and will be visible until around 24 January. Astroblogger Dr Ian Musgrave says Lovejoy is bright enough for sky watchers with clear, dark skies to view it with the unaided eye -- although it is best viewed through a telescope. "Lovejoy can be best found by looking just below and to the left of the constellation Orion (known colloquially in Australia as 'the saucepan' ) in the northern sky," says Musgrave. "It is visible from anywhere in Australia and most of the southern hemisphere at the moment, but now people in the northern hemisphere will begin to get a better view. "But don't wait too long to check out Lovejoy, as moonlight will begin to interfere with your view by the end of the month," he says. The comet, which was discovered in 2014 by amateur Australian astronomer Terry Lovejoy, comes from the Oort Cloud, a distant halo of icy bodies and frozen debris at the outer edge of the solar system. It last visited the inner solar system about 11,500 years ago and is not expected to return for another 8000 years.

phys.org/news/2015-11-team-gas-emissions-comet-67pchuryumov-gerasimenko.html Team maps gas emissions from comet 67P/Churyumov-GerasimenkoNovember 12, 2015 These images, acquired with Rosetta's OSIRIS wide-angle camera using specific wavelength filters, map the emissions of three gases from the surface of comet 67P/Churyumov-Gerasimenko. From left to right, the panels show hydroxyl molecules …more The European Space Agency's Rosetta spacecraft began orbiting comet 67P/Churyumov-Gerasimenko in August 2014, providing the closest and most detailed look at a comet to date. Now, a team led by astronomers at the University of Maryland has used data from Rosetta's Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS) cameras to generate maps of multiple gas emissions just above the comet's surface. The work has already revealed surprising physical and chemical processes never before seen up close. The researchers will present their findings at the 47th Annual Meeting of the American Astronomical Society's Division for Planetary Sciences, November 8-13, 2015, in National Harbor, Maryland. The group focused on gases produced by the breakdown of water molecules (H2O) and hydrogen cyanide molecules (HCN). Both reactions are caused by ultraviolet radiation from the sun, and the gases produced by these reactions give off light at characteristic wavelengths that can help researchers identify where and when the specific gases are produced. "Because Rosetta is very close to the comet, it can observe gas much closer to the nucleus than can be seen from Earth," said Dennis Bodewits, an assistant research scientist in astronomy at UMD who will present the group's findings. "This has already revealed unanticipated physical processes that are important both in breaking apart the original molecules of gas and in causing the fragments to shine." When water (H2O) is broken down, it produces molecular hydrogen (H2) and a single oxygen atom. This oxygen remains in an excited state, which allows it to directly emit a photon instead of waiting to absorb a photon from the sun. This means that this excited oxygen can be used as a proxy to track the location and amount of water. "Since we first arrived at the comet, the emissions have been far stronger than expected," Bodewits said. Early measurements of water by the Microwave Instrument for the Rosetta Orbiter (MIRO) camera provided a basis for these predictions. "However, these measurements came into agreement when the comet drew closer to the sun." The team was also surprised by the signature from cyanide gas (CN), produced as a byproduct of the breakdown of hydrogen cyanide (HCN). In early Earth-based observations, cyanide could be seen emitting light thousands of kilometers away from 67P's nucleus. However, when viewed up close as the comet approached the sun, the light emitted by cyanide fragments dropped off very sharply within about 10 kilometers. "This indicates that, as with oxygen formed by the breakdown of water, cyanide also emits light immediately after it is formed," Bodewits explained. "As an interesting historical note, cyanide emission is very bright and was the first molecular emission identified in comets. This led to panicked news headlines in 1910, when both Halley's comet and the Daylight comet visited Earth. We now know that cyanide concentrations in comets are too low to be of any concern." More information: The presentation, titled "Observed changes in the physical environment and chemistry in the inner coma of 67p/Churyumov-Gerasimenko," Dennis Bodewits et al., will be presented at 10:50am on Friday, November 13, 2015, at the at the 47th Annual Meeting of the American Astronomical Society's Division for Planetary Sciences. aas.org/meetings/dps47 Provided by: University of Maryland search and more info

Credit: Gerald Rhemann/www.astrostudio.at; Sky & Telescope: www.skyandtelescope.com/Comet LINEAR (formally designated 252P) is coming into view for observers in the Northern Hemisphere during the last few days of March. The comet's arrival has skywatchers excited because this icy space rock is 100 times brighter than expected. From the Southern Hemisphere, observers have recently been able to spot the comet with the naked eye in very dark areas. Although the moon's light will flood the sky in the Northern Hemisphere, the comet may be visible with binoculars in a sufficiently dark area. "Don't expect Comet LINEAR to be obvious, with a long tail," Sky & Telescope senior editor Kelly Beatty said in a statement. "Its light isn't concentrated in a single point, but instead is spread out in a soft, round glow, larger than the moon but many thousands of times dimmer." [Skywatching in 2016: The Year's Must-See Events (Calendar)] Advertisement Skywatchers observing the comet with telescopes may see the greenish haze surrounding it. This green glow is thought to be created by atoms of diatomic carbon surrounding the comet and fluorescing in the sunlight, the statement said. Observers should go outside at least 90 minutes before sunrise in a dark area and look for the comet between the constellations Sagittarius and Scorpius. The planets and stars can also serve as guideposts for finding the comet. LINEAR will be in line with Mars and Saturn on March 29, and in line with Saturn and Antares (a bright, red star in the constellation Scorpius) on March 31. The moon will also be close by, particularly on March 30; it will be just 3 degrees to the lower right of the comet.

www.universetoday.com/128589/summer-comet-guide-observing-x1-panstarrs/ A Summer Comet: Our Guide to Observing X1 PanSTARRS3 May , 2016 by David Dickinson Comet C/2013 X1 PanSTARRS from early January 2016, shortly after a reported outburst. Image credit and copyright: Hisayoshi Kato. Ready for one of the better binocular comets of 2016? Emerging from behind the Sun and a surprise outburst in January, Comet C/2013 X1 PanSTARRS is about to put on its summer show. The waning crescent Moon just crossed paths with the comet in the dawn sky on its way to New on May 6th, and the time to start tracking it is now as it plunges southward across the ecliptic this weekend. Discovered on December 4th 2013 by the prolific PanSTARRS 1 survey, early signs suggested that Comet C/2013 X1 PanSTARRS would be special. First, it was sighted 8.9 AU from the Sun, just inside the orbit of Saturn. This is a good distance for a comet discovery, suggesting an intrinsically bright comet. We’re typically monitoring the IAU’s naming list for new comet discoveries, and can remember way back in late 2013 noting that this particular comet might just be something of note in mid-2016. And here we are. The good news is, X1 PanSTARRS is brightening ahead of predictions, not unusual for a comet post-perihelion. Updated observations for the comet on the Comet Observer’s Database (COBS) place X1 PanSTARRS at brighter than magnitude +8 ‘with a bullet.’ It’ll soon surpass Comet 252/P LINEAR as the brightest currently observable comet in the sky. Currently, Comet X1 PanSTARRS is located just below the circlet of Pisces asterism. The comet is visible in the dawn through May, and is currently observable from 35 north latitude to 70 degrees south. The comet will ride high in the southern hemisphere in the coming months, and low to the south through the summer for folks up north. C/2013 X1 PanSTARRS will transition to the evening skies in late June as it crosses its opposition point at 180 degrees elongation from the Sun.

But while we wait for the next spectacular visitor from the outskirts of our solar system, we can enjoy smaller, dimmer comets that pass close enough from time to time to be seen in binoculars and telescopes. This month, a periodically returning comet designated 21P/Giacobini-Zinner will be bright enough to be seen in binoculars and small telescopes. It is expected to continue to brighten until the morning of Sept. 10, when it will pass within 36.3 million miles (58.5 million kilometers) of Earth on its way around the sun. Sometimes, if its orbit is just right, a comet will appear to pass close to major stars in the sky, which makes it easier for non-experts to find the object. And, even better, comets occasionally pass close to the positions in the sky of distant deep-sky objects. This sets up spectacular telescope views and wide-field photo opportunities for tripod-mounted cameras or close-up views using DSLR cameras affixed to tracking telescopes. [Amazing Photos of Comet 21P/Giacobini-Zinner and Comet 46P/Wirtanen] Recently, the periodically returning Comet 21P/Giacobini-Zinner has become bright enough to be seen in binoculars under dark skies. Next week, it will make its closest approach to Earth. Over the upcoming weeks, the path of the comet will carry it along the Milky Way, setting up a series of picturesque encounters with many deep-sky objects. Your favorite astronomy app can help you spot those events. This screen cap presents the sky at 1 a.m. local time on Sept. 8, 2018.

Lucky for us, Comet 21P's path will take it along the Milky Way, setting up a series of spectacular close encounters during September and October. And many of the best ones will occur when the moon is not very bright, as is the case this week. In this edition of Mobile Stargazing, we'll tell you how to use your favorite astronomy app to hunt down Comet 21P. We'll also present a timeline of events that will give you the opportunity to see or photograph the comet in a picturesque setting. And Comet 21P will just be a warm-up. Astronomers eagerly anticipate the arrival later this year of another, even brighter comet: 41P/Wirtanen. With the SkySafari 6 app for Android and iOS, you can see the path of any selected solar-system object through the sky (gray line with labeled dates). For the next several nights, Comet 21P/Giacobini-Zinner will drift southward through Auriga, passing the Starfish and Pinwheel star clusters (Messier 38 and 36 respectively) on Friday night and the Messier 37 cluster on Sunday night. Credit: SkySafari App Finding Comet 21P in the skyComet 21P/Giacobini-Zinner is located in the northeastern sky and is visible in both the Northern and Southern hemispheres. It rises in late evening and then is carried higher in the sky as the night wears on. Right now, the comet's brightness is approximately magnitude 7.5, and skywatchers have spotted it easily using binoculars in dark-sky locations. [Bright Comets of 2018: When, Where and How to See Them] This comet's orbit is inclined by 32 degrees from our solar system's plane, so rather than moving east-west as the moon and planets do, it follows a southward path through the stars — which is down and toward the right for Northern Hemisphere observers. Between now and Sept. 13, the comet will pass through the roughly circular constellation Auriga. After that, 21P will move through the feet of Gemini's western twin, Castor, for a few nights and then follow the boundary between Orion and Gemini until Sept. 22. The comet will finish September by following the Milky Way, traveling through the modest constellation of Monoceros, more or less toward the very bright star Sirius. Then, 21P will spend October skirting the eastern edge of Canis Major. It's unknown how long the comet will remain a target for binoculars, but telescope users with tracking capability should be able to find and view 21P for the next two months or so. You can use your astronomy app to display the path of a comet against the sky. In the SkySafari app Plus and Pro versions, use the search option, select the comet and tap the Center icon on the Info page. Open the Settings/Solar System menu and put a check mark in the Selected Object Path box. The sky will now include the comet's path, with labeled tick marks at one-day intervals. You can also advance to future dates and see where the comet will be at any given date and time. [Best Binoculars for Earth and Sky] On Aug. 17, 2018, Paul Mortfield captured this spectacular image of Comet 21P passing the Heart and Soul nebulas (IC 1848 and IC 1805) in Cassiopeia. The bright star clusters at the upper right constitute the well-known Double Cluster. This is a 2-minute unguided exposure using a DSLR camera equipped with a 200-mm lens.

Here's what you need to knowBy Joe Rao / www.space.com/author/joe-rao1-6-2023 This may very well be the last time that C/2022 E3 comes our way again.(Image credit: Chris Schur) Typically, during the course of a year about a dozen comets will come within the range of amateur telescopes. Most quietly come and go with little fanfare, but some are particularly noteworthy. During the upcoming weeks, a newly-discovered comet will be making a relatively close approach to the Earth. On Feb. 1, comet C/2022 E3 (ZTF) will pass to within 28 million miles (42 million km) of our planet, its first approach in 50,000 years. While this will no doubt entice many skywatchers to attempt to view the comet, whether or not one will actually be able to see it will depend on a variety of factors including location and light pollution from both natural and artificial sources. But don't be dismayed! Even if you don't have the right gear or conditions to see comet C/2022 E3 (ZTF), the Virtual Telescope Project will be hosting a free livestream of the comet beginning at 11:00 p.m. EST on Jan. 12 (0400 GMT on Jan. 13). You can watch the live webcast courtesy of the project's website(opens in new tab) or on its YouTube channel(opens in new tab).

The comet has been named C/2022 E3 (ZTF), and when it last flew past the Earth, Neanderthals were walking the planet. The January 2023 comet will become visible to the naked eye at the end of the month. Viewers in the northern hemisphere have the best chance to see it in the early morning hours.To kick off 2023, Earthlings could catch an extraordinary sight in the sky as a recently discovered comet travels past our world. The comet, dubbed C/2022 E3 (ZTF), was first sighted in March 2022, according to NASA. It likely traveled hundreds of billions of miles to reach the inner solar system. C/2022 E3 (ZTF) will be closest to the sun on Jan. 12 and will pass Earth at a distance of 26.4 million miles on Feb. 2, NASA said. Start the day smarter. Get all the news you need in your inbox each morning. If the comet ever returns, it won't be at least for another 50,000 years, experts say. Here's what you need to know about viewing the once-in-a-lifetime event. Viewing the comet: A rare green comet is headed our way. Here's how to see it without a telescope. Meteor showers of 2023: A visual guide on where and when to view the year's 11 sky shows April: Astronomers confirm size of largest comet ever discovered, bigger than Rhode Island Where can I see Comet C/2022 E3 (ZTF)? What time is it visible?For people in the Northern Hemisphere, C/2022 E3 (ZTF) will be visible in the predawn sky with binoculars or a small telescope for all of January. The Southern Hemisphere will be able to observe the comet at the start of February, NASA said. Between city lights, pollution and/or the moon's glare, viewing a comet can be challenging. To best observe C/2022 E3 (ZTF), you'll want to find dark, clear skies. A December telescopic image captured by astrophotographer Dan Bartlett shows C/2022 E3 (ZTF) with an impressive "brighter greenish coma, short broad dust tail, and long faint ion tail," NASA writes. The comet's coma "has a distinctive green color in photographs due to its chemical composition," Space.com reports, adding that the color "suggests the presence of diatomic carbon, or dicarbons." Can I see the comet with a naked eye?Depending on viewing conditions and the comet's brightness, it might be possible to see C/2022 E3 (ZTF) with a naked eye. "Comets are notoriously unpredictable, but if this one continues its current trend in brightness, it'll be easy to spot with binoculars, and it's just possible it could become visible to the unaided eye under dark skies," NASA noted in its January 2023 skywatching tips. "This comet isn't expected to be quite the spectacle that Comet NEOWISE was back in 2020. But it's still an awesome opportunity to make a personal connection with an icy visitor from the distant outer solar system," the agency added. In September: New images from James Webb Space Telescope showcase Neptune and its rarely seen rings Where did C/2022 E3 (ZTF) originate from?According to CBS and Newsweek, experts say that the comet likely originated from the Oort Cloud – the most distant region of our solar system that NASA describes as "a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger." www.msn.com/en-us/news/technology/a-newly-discovered-green-comet-is-nearing-earth-and-it-may-be-visible-to-the-naked-eye/ar-AA1655aK?ocid=msedgdhp&pc=U531&cvid=8ecc16d130244dc38e1436a0918935c3

Comet C/2022 E3 (ZTF) will be positioned close to Mars in the Taurus constellation, making it easier to locate as it dims as it speeds away from Earth. The comet will appear beside the Red Planet from Feb. 9 through Feb. 14, after which it will begin approaching the Orion and Eridanus constellations. For viewers in the continental United States, Mars is positioned high in the night sky roughly an hour after sunset this month, making the comet primed for early evening viewing. If skies aren't clear in your area or you aren't able to make it outside to see comet C/2022 E3 (ZTF) as it nears Mars, you still have a great opportunity to view this celestial spectacle. The Virtual Telescope Project is hosting a free telescope livestream of the comet's Red Planet approach on the project's website(opens in new tab) and YouTube channel(opens in new tab). The livestream will begin on Saturday (Feb. 11) at 2:00 p.m. EST (1900 GMT). For skywatchers who want to get a good look at the comet in person, Mars offers a great reference point for locating this "messenger from the outermost reaches of our solar system." Throughout February, the Red Planet is between magnitude -0.2 and +0.4, making it not too difficult to spot in most areas without significant light pollution. Aside from Mars, Venus and Jupiter are positioned well in the early evening sky for viewing as well. Be sure to see our guide on the brightest planets in February's night sky and how to see them to soak up our solar system neighbors throughout the month. Mars is located high overhead around 7:00 p.m. local time throughout the month near the Auriga and Taurus constellations. If you aren't familiar with how the planet appears in the sky, there are a large number of popular stargazing apps available for mobile devices that can help you locate the comet, Mars and nearby constellations.
