Georgia science museum studying meteorite seen over metro Atlanta
The Tellus Science Museum has acquired part of the unusual meteor that blasted across the metro Atlanta area last week.
Its entry was so intense that it triggered the Geostationary Lightning Mappers (GLM) aboard NOAA's GOES satellites—devices normally used to detect lightning.
The outer space rock was the 29th meteorite documented in Georgia and the second time one ever hit a home.
CARTERSVILLE, Ga. - A piece of outer space rock that fasciated people across the Southeast last week is now a part of Georgia's Tellus Science Museum's collection.
The museum announced that it has acquired the recovered meteorite that shot through the sky on June 26 before part of it landed in Henry County.

The backstory
NASA says the meteor entered Earth's atmosphere at 12:25 p.m. EDT on June 26, first appearing 48 miles above Oxford, Georgia. Traveling southwest at an estimated 30,000 miles per hour, the object disintegrated at an altitude of 27 miles above West Forest, unleashing energy equivalent to about 20 tons of TNT.
The breakup produced a powerful pressure wave that reached the ground, creating loud booms and tremors that startled residents. According to NASA, "some large windows may have vibrated or even cracked." The fireball was caused by an asteroidal fragment approximately three feet in diameter and weighing over a ton.
Its entry was so intense that it triggered the Geostationary Lightning Mappers (GLM) aboard NOAA's GOES satellites—devices normally used to detect lightning. Doppler radar also picked up falling debris above Henry County.
Witnesses across Georgia and neighboring states—including as far south as Macon and as far north as Upstate South Carolina—reported seeing a flash of white light followed by what many described as an "earthquake." However, the U.S. Geological Survey confirmed no seismic activity occurred. Officials say the shaking was the result of a sonic boom.
Local perspective
A resident of Henry County, Georgia, reported a rock coming through their roof around the time they heard the sonic boom from the fireball. It left behind a hole in the ceiling about the size of a golf ball and a crack in a laminate floor at the home southeast of Atlanta, according to the National Weather Service office in Peachtree City, Georgia.
"We are presuming that a piece of the object fell through their roof," the weather service said.
Dashboard and doorbell cameras across several states in the southeastern U.S. states caught glimpses of the fireball that appeared to be plummeting straight down.
What they're saying
"We're very fortunate to have this piece," said Amy Gramsey, Tellus' director of curatorial services. "A meteorite hunter found the specimen on Friday, June 27, in Henry County. It's a 150-gram chondrite meteorite—a stony-type meteorite containing small mineral granules."
Officials with the Tellus Science Museum say that last Thursday's fall was the 29th meteorite documented in Georgia and the second incident of one hitting a home - the first being in MAy 2009 in Cartersville.
"Meteorite landings like this are pretty rare," said Tellus' astronomy program manager Karisa Zdanky. "Space rocks and other debris enter Earth's atmosphere often, but they usually burn up before reaching the ground – which is the requirement to be called a meteorite. It's uncommon to have a meteor so bright and so big that it can be witnessed in the day and produce such sizable meteorite fragments."
What's next
The new specimen has not been named yet, but Tellus staff are expecting it to be on display for the public by the end of the summer.

Satellite spies both ISS and China's Tiangong space station
When you buy through links on our articles, Future and its syndication partners may earn a commission. Since 1998, when the International Space Station (ISS) launched, there has been a place for astronauts around the world to run experiments in space, from growing food to learning how low-Earth orbit affects the human body. More recently, the Chinese Tiangong Space Station was fully completed, with its third and final module, the Mengtian, added on Oct. 31, 2022. Tiangong sits at the same height as the ISS. The ISS is a joint venture between NASA, Roscosmos, the European Space Agency (ESA), the Japanese Aerospace Exploration Agency (JAXA) and other organizations. It's been continuously inhabited since 2000 and serves as a microgravity laboratory for research in biology, physics, medicine and earth sciences. The ISS is significantly larger than the Tiangong Space Station, as the ISS has 16 modules while Tiangong only has three. As China was excluded from the ISS program, it created its own space station, Tiangong, which shows the nation's prowess in space exploration. Tiangong, which means "Heavenly Palace" in Chinese, was built by the Chinese Manned Space Agency (CMSA) and provides a platform for scientific research for countries not involved in the ISS program. These two photographs were taken from space, about 250 miles (402 km) from Earth. These two photos were taken by a Maxar WorldView Legion satellite from low-Earth orbit. In a tweet, Maxar Technologies discussed how their satellites could capture these images with crisp clarity as both space stations continue to move in their respective orbits. It's difficult to photograph something moving as quickly as the ISS or the Tiangong Space Station. The ISS orbits Earth every 90 minutes at a speed of about 17,500 mph (28,000 km/h) and the Tiangong moves at a similar rate. Being able to capture the detail on both space stations shows the timing and engineering capabilities of the Maxar satellite. You can read more about the ISS, the Tiangong Space Station, and observation satellites as companies like Maxar continue to study Earth from space.

Biting the 'Bullet': Amazing new JWST photo shows titanic collision of galaxy clusters
When you buy through links on our articles, Future and its syndication partners may earn a commission. NASA's James Webb Space Telescope (JWST) has produced a new image of the Bullet Cluster, which is a titanic collision between two individual galaxy clusters. The image, produced in conjunction with NASA's Chandra X-ray Observatory, reveals not only the location and mass of dark matter present, but also points the way toward one day figuring out what dark matter is actually made of. In the new image, we see the hot gas within the Bullet Cluster in false-color pink, detected by Chandra. The inferred location of dark matter is represented in blue (also false color), as measured by the JWST. Note that the blue and the pink are separate — what has caused the dark matter and the gas to separate, and how were astronomers able to produce this map of the material within the Bullet Cluster? Located 3.9 billion light-years away, the Bullet Cluster has been an occasionally controversial poster child for dark-matter studies. Back in 2006, the Hubble Space Telescope and the Chandra X-ray Observatory worked together to image the Bullet, showing the presence of its dark matter based on how light from more distant galaxies was being gravitationally lensed by the dark matter's mass. Collisions between galaxy clusters are the perfect laboratories for testing our ideas about dark matter, because they are nature's way of throwing together huge amounts of the stuff. This gives us a chance to test how dark matter particles interact with each other, if at all, and the degree of any interaction would be a huge clue as to the properties of the mysterious dark matter particle. Yet despite the dramatic Hubble and Chandra images, the Bullet Cluster — and, indeed, other galaxy cluster collisions — haven't always played ball. For instance, the velocities at which the sub-clusters are colliding seem too high for the standard model of cosmology to explain. Now the JWST has entered into the fray. A team led by Ph.D. student Sangjun Cha of Yonsei University in Seoul, South Korea, and professor of astronomy James Jee at both Yonsei and the University of California, Davis, have used the most powerful space telescope ever built to get a best-ever look at the Bullet Cluster. Hubble and Chandra had previously shown that, as the two individual galaxy clusters in the Bullet Cluster collided, the galaxies and their surrounding dark matter haloes had passed right through each other. This makes sense for the galaxies — the distances between them are so great that the chance of a head-on collision between any two is slim. It also suggests that the degree with which dark matter particles interact with each other — what we refer to as their collisional cross section — is small; otherwise, the interaction would have slowed the clouds of dark matter down, and we would detect it closer to where Chandra sees the hot, X-ray emitting intracluster gas. In contrast to the dark matter, these huge gas clouds can't get out of each other's way, so they slam into each other and don't progress any further. The end result is that the hot gas is found stuck in the middle of the collision, and the galaxies and dark matter belonging to each sub-cluster are found on opposite sides, having glided right through one another. "Our JWST measurements support this," Jee told "The galaxy distribution closely traces the dark matter." JWST was able to produce a better map of the distribution of matter, both ordinary and dark, in the Bullet Cluster by detecting, for the first time, the combined glow from billions of stars that have been thrown out of their galaxies and are now free-floating in the space between the galaxies in each sub-cluster. Cha and Jee's team were then able to use the light from these "intracluster stars" to trace the presence of dark matter and gain a more accurate map of its distribution in the Bullet Cluster. However, this has just raised more mysteries. The more refined map of the dark matter shows that, in the larger sub-cluster, on the left, the dark matter is arranged in an elongated, "hammerhead" shape that, according to Jee, "cannot be easily explained by a single head-on collision." This elongated mass of dark matter is resolved into smaller clumps centered on what we call the brightest cluster galaxies — giant elliptical galaxies that are the brightest galaxies in the sub-cluster located at its gravitational core. In contrast, the dark matter halo around the sub-cluster on the opposite side is smaller and more compact. Cha and Jee's team suspect that the elongated, clumpy mass of dark matter could only have formed when that particular sub-cluster, which was a galaxy cluster in its own right before the Bullet collision, underwent a similar collision and merger with another galaxy cluster billions of years before the formation of the Bullet. "Such an event would have stretched and distorted the dark-matter halo over time, resulting in the elongated morphology that we observe," said Jee. Despite the new discoveries such as this from JWST's more refined observations of the Bullet cluster, it is still not enough to resolve the issue of the collision velocities of the two sub-clusters. "Even with these updates, the required collision velocity remains high relative to expectations from cosmological simulations," said Jee. "The tension persists and remains an active area of research." RELATED STORIES — What is dark matter? — James Webb Space Telescope (JWST) — A complete guide — Astonishing 'halo' of high-energy particles around giant galaxy cluster is a glimpse into the early universe Dark matter makes up over a quarter of all the mass and energy in the universe, and roughly 85% of all matter, so figuring out its secrets, in particular its collisional cross-section and the cause of those high velocities, is going to be essential if we want to better understand this universe in which we live. Alas, the JWST observations of the Bullet Cluster alone are not enough to confirm what the collisional cross-section of dark matter must be. However, they do tighten the estimate of the upper limit for the value of the cross-section, constraining the list of possibilities. Astronomers are already in the process of rigorously measuring as many galaxy cluster collisions as possible, seen from all angles and distances, to try and constrain this value further. Gradually, we'll be able to rule out different models for what dark matter could be, until we're left with just a few. Coupled with experimental data from direct dark matter searches from detectors deep underground, such as the LUX-ZEPLIN experiment at the Sanford Underground Research Facility in South Dakota, we could soon be on the cusp of answering one of science's greatest mysteries: what is dark matter? The JWST observations were reported on June 30 in The Astrophysical Journal Letters.
