nerdist.com/skull-carved-from-4-billion-year-old-meteorite-set-for-auction/ Skull Carved From 4-Billion-Year-Old Meteorite Set For AuctionPosted by Sarah Keartes / nerdist.com/author/sarah-keartes/ November 19, 2015 We’ve seen meteorite knives, and meteorite swords, but here’s a new one: a space-rock skull is up for sale at Los Angeles’ Bonhams auction house. The sculpture was carved by Bali-based artist Lee Downey from a hulking 105 pound (47.6 kg) chunk of the Gibeon Meteorite, which was found in Namibia in 1836. Despite reports that the piece is made from “one of the rarest” forms of meteorite found on Earth, some 25 tons of Gibeon space rocks have been recovered to date. And while specimens can no longer be exported from Namibia, it’s still one of the most commonly available meteorites on the market. Before you start reaching for your Benjamins, you should know that you’ll need a lot of them. Four-billion-year-old celestial objects don’t come cheap, rare or not. We estimate that the original piece the skull was cut from would have fetched somewhere around $150,000. Gibeon meteorites are typically composed of iron, nickel and small amounts of cobalt, but every so often, other minerals make their way into the mix. These inclusions can increase the piece’s value, and as you can see in the photos, Downey’s skull, dubbed “Yorick” after the fictional character in William Shakespeare’s “Hamlet,” has one just above the right eye. The yellow-orange stripe is a block of tridymite, a morph of silica (glass) that forms when the element fuses at high temperatures. Speaking of temperature, you’ve no-doubt noticed those beautiful lines running across the skull. That crystalline pattern, known as the Widmanstatten pattern, is characteristic of meteorites that have cooled over millions of years in the vacuum of space. By brushing the skull in a nitric acid wash, Downey was able to tease the pattern out – much in the same way that Bourdain did with his space knife.

I heard a news flash a few days ago of a meteorite impact just outside of Las Vegas that the police were investigating on scene but I haven't been able to find anything more about it. Does anybody know anything about this?

Morgan..(Skywalker)- One of our newer members (stormy) and a personal friend saw a green meteor tonight... Apparently a fireball. Santa Claus? Lol. I've only seen two now out of thousands...the first was an incident very similar to yours.. Coincidence ? I read somewhere that the govt at one time was investigating them out of NM I think...would love to find one.. Especially from a green meteor.

I've seen a few green ones. They are pretty spectacular. Much brighter than the ordinary ones that zoom by. They have a tendency to light up the whole sky when they occur. And yes, the government was investigating them back in the 1950s and 60s. I don't remember if it was a part of Project Blue Book or a separate investigation but it was pretty detailed. I don't think they ever came to a definite conclusions about them other than they are moving pretty darned fast.

www.universetoday.com/128969/super-bright-fireball-spotted-across-u-s-northeast/ WOW... Super Bright Fireball Spotted Across U.S. Northeast17 May , 2016 by Jason Major / www.universetoday.com/author/jason-major/Bright meteor captured on a webcam in Portsmouth, New Hampshire on May 17, 2016. Via www.portsmouthwebcam.comIt came from outer space—literally! On Tuesday, May 17, 2016, the early morning sky briefly lit up with the brilliant flash of a fireball—that is, an extremely bright meteor—over much of eastern New England states and even parts of southeastern Canada. The event, which occurred around 12:50 a.m. EDT (04:50 UTC), was reported by witnesses from Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, Ontario, and Québec, and captured on several automated cameras like a webcam in Portsmouth, NH (seen above) and a police dashcam in Plattsburgh, NY (below). The fireball appeared to be moving from southwest to northeast and for some witnesses created an audible sonic boom, heard (and felt) several minutes later. See more videos of this event from local news stations WMTW and WGME (Maine) and WMUR (New Hampshire) and from the Ogunquit police department on Twitter. Meteors are the result of debris in space rapidly entering Earth’s upper atmosphere, compressing the air and causing it to quickly release energy in the form of heat and optical light. If the entering object is massive enough it may violently disintegrate during its fall, creating both light and sound. This particular meteor technically classifies as a bolide, due to its brightness, eruption, and visible fragmentation. Learn more about the various types of meteors here. No reports of a meteorite impact at ground level have been made although I must assume there will be individuals who go on the hunt—meteorite fragments, especially those associated with witnessed events, can be quite valuable.

Meteor Streaking Across Arizona Sky Caught on Video
Meteor Streaking Across Arizona Sky Caught on Video
Published on Jun 3, 2016
Fireball Lights Up the Sky Over Arizona (Video) A fireball lit up the skies around Phoenix Thursday, leaving groggy residents wondering if it was a meteor, an explosion or something else.
Arizona DOT cameras captured mysterious trails in the sky around the Phoenix area Thursday morning after reports of a possible meteor. Arizona DOT cameras captured mysterious trails in the sky around the Phoenix area Thursday morning after reports of a possible meteor. (Credit: Arizona DOT) NASA said a small asteroid zipped into Earth's atmosphere above Arizona at a breezy 40,000 mph. After lighting up Phoenix, NASA estimates it moved south, with pieces of the meteor landing somewhere north of Tucson.
A Phoenix Police Department spokesman told CNN that they got more than 60 calls about the meteor, which was seen at about 4 a.m. (7 a.m. ET).
"Many of the callers mistakenly believed they were being burglarized due to the accompanying sound created," Sgt. Jonathan Howard said.
Phoenix resident John Burgmeier said he heard multiple booms as the fireball came out of the northeast.
"(It) literally made the entire sky bright," he said. "It was like it was daytime."
The fireball was also captured on surveillance cameras at a Phoenix school.
People who missed the show woke up to see the squiggly trails it left behind. A small asteroid blazed a spectacular trail through Arizona's skies early Thursday morning (June 2), and the dramatic celestial event was caught on video.
A space rock about 10 feet (3 meters) wide slammed into Earth's atmosphere east of the Arizona town of Payson just before 4 a.m. local time (7 a.m. EST; 1100 GMT) Thursday, NASA officials said. The impact of asteroid with the air created a fireball so bright that it saturated NASA meteor cameras in the region, as as this video of the brilliant event shows.
The unnamed asteroid was likely traveling at about 40,200 mph (64,700 km/h) when it entered Earth's atmosphere, at an altitude of 57 miles (92 kilometers) above the Tonto National Forest, NASA officials said. Eyewitness accounts suggest that the object headed pretty much due south; it was last seen at an altitude of 22 miles (35 km) above the forest, the officials added.

Nope missed the whole thing...but we do see them whiz by now and then to burn up in the atmosphere..always blue or green. Seldom do they get through. It did register on seismograph's like a quake though.

Henri Galimberti on Flickr via CC 2.0 When you picture a meteorite, you probably imagine a massive hunk of space rock hurtling its way through Earth’s atmosphere. The objects that survive this trip sell for tens of thousands of dollars at auctions, become parts of museum displays, and make national news. But you—yes, you—can find your very own meteorites, and you don’t need to be a millionaire to do it. You just need to think small. Micro, to be exact. Like meteorites, micrometeorites are space rocks that fall to Earth—but as their name suggests, they are also extremely tiny, less than a tenth of an inch in width. And they’re way more numerous than their big cousins: Approximately 3,000 tons—that's roughly the weight of 47 sperm whales—of micrometeorites smash into the ground each year, compared to a piddling 55 tons of meteorites. Which means some of these objects could be sitting in your backyard right now. There's just one problem: How do you expect to dig up wee rocks that range from a fraction of a millimeter to 2mm in diameter (switching to metric units for specificity's sake)? Luckily, many micrometeorites are magnetic, which means you can collect them by simply dragging a strong magnet over the ground. (Of course, it's a little more nuanced then that—keep reading for more information.) Norwegian researcher Jon Larsen has hunted micrometeorites all over the world, and he wants to recruit amateurs into the space-rock-collecting club. While his full instructions for finding micrometeorites are detailed, they also include directives, such as weighing each sample and keeping careful notes, that will appeal more to serious researchers than to casual collectors. Read on for a stripped-down version of his rubric. Happy hunting! Tools and materials Three clear plastic sandwich bags Permanent marker (optional) Neodymium magnet, ideally with a hook to use as a handle Twist ties or rubber bands String (optional) Gloves (optional) Coarse sieve (opening around 1.5 mm wide, Number 12 or 14 mesh) Fine sieve (opening around 0.4 mm wide, Number 40 or 45 mesh) Plate or shallow dish, water, and dish soap (optional) Glass slide Microscope Toothpick Instructions *Reserve one of the sandwich bags, optionally marking it with the date and the location of your collection foray. This will act as a receptacle for your micrometeorite samples. *Wrap the neodymium magnet in the two remaining sandwich bags so that two layers of clear plastic sit flat over the magnet. One layer will prevent the micrometeorites from getting permanently stuck to the strong surface, and the other will act as a backup in case the first one tears. *Secure the bags by fastening their openings around the hook with a twist tie or rubber band. Optionally, tie a string around the magnet so you can suspend it as you run it over the ground, rather than crouching down to drag it. *Place the plastic-covered magnet on a rooftop, sidewalk, or your own backyard, and pull it around all over the area. You’ll probably have the most luck in an area that concentrates downpours, like in gutters or the spots where they empty out. *The neodymium should attract any magnetic particles, eventually covering the plastic in a layer of grimy-looking…stuff. You may want to wear gloves when handling it. *Holding the magnet over the first, labeled sandwich bag, pull away the plastic layers. Once they’re free of the magnet, any micrometeorites on the plastic will fall into the clean sandwich bag. *Repeat this process until the sample bag contains a decent scoop of grime. Then wash your hands thoroughly and take your finds home for the next steps. *Run the contents of the bag through a coarse-meshed sieve and then a fine-meshed one to sort the sample into three different piles. *Material that didn’t fit through either sieve is wider than 1.5 mm, and probably doesn’t contain micrometeorites. Material that fit through both sieves is less wide than 0.4 mm and will be more difficult to handle. Instead, we’ll concentrate on the Goldilocks material that fit through the coarse but not the fine sieve. *If your Goldilocks sample just looks like dirt, place it on a plate or a shallow dish and wash it with warm water and a little bit of dish soap. *Scoop some of the clean material onto a glass slide and place it under the microscope so you can see it up close. Not every magnetic particle you pick up will be a micrometeorite, so concentrate on looking for tiny metallic spheres. While you search, you can wield a toothpick to move the material around, spread it out, or isolate a particularly promising-looking piece. *When you find these spheres, zoom in to examine the details on their surfaces. Then compare your findings to the objects on Larsen's Project Stardust page. You may turn up a decent number of human-made magnetic particles before you find the micrometeorites you seek, so remember to be patient. www.popsci.com/hunt-micrometeorites?con=TrueAnthem&dom=tw&src=SOC&utm_campaign=&utm_content=59fd8fa904d3014bb4a6220e&utm_medium=&utm_source=

www.coasttocoastam.com/article/watch-streaking-meteor-turns-turkish-sky-green/Watch: Streaking Meteor Turns Turkish Sky GreenStaff Reporter Sep 06, 2023 September 11, 2023 On September 2, a mesmerizing fireball lit up Turkey's night sky, leaving vivid green trails. Social media videos captured this spectacular event as it unfolded over Erzurum City and Gumushane Province. One video shows a car on a quiet road witnessing the meteor's green glow, which intensified as it neared, turning into bursts of brilliance before fading into darkness. Turkish Skies Turned Green As the Meteor Travels Through the Clouds Numerous eyewitnesses captured astonishing visuals as a meteor streaked through the sky, igniting it with mesmerizing bursts of green light. One striking video, posted by Nahel Belgherze on X, portrays a child playing with a balloon against a cloudy backdrop when the meteor abruptly darts across the sky. (Photo : Pixabay/DilanArezzo) Vibrant Green Fireball Lights Up Turkish Skies; Mesmerizing Video Captures the Fiery Streak The meteor then bursts into a brilliant sphere of light, revealing the contours of the surrounding clouds. In a fleeting moment, it disappears, returning the sky to its familiar darkness. These eerie videos were recorded as the meteor traversed the skies above Erzurum City and Gumushane Province in eastern Turkey during the previous night. Despite the compelling footage, authorities have yet to offer an official explanation regarding the object's origin. This celestial event unfolded shortly after the Perseid meteor shower, which graced the skies between July 17 and August 19. Similar phenomena have made headlines elsewhere, such as in Colorado, where a massive fireball illuminated the night sky. This spectacle occurred at approximately 3:30 a.m., witnessed by only a handful of people awake at that hour. Many residents shared their doorbell and security camera footage, documenting the celestial event's breathtaking display in the heavens.
