The universe appears to have sent us an early Christmas present: the large asteroid that tumbled safely past Earth last week was, in fact, two asteroids melded into one object that resembles a snowman. The asteroid, named 2024 ON, zipped past Earth on Sept. 17 at 19,842 mph (31,933 kph), which is roughly 26 times the speed of sound. The space rock is huge — 1150 feet (350 meters) long, about the size of a skyscraper — but it safely floated past Earth at a distance of 620,000 miles (1…

X-rays from a nuclear explosion could redirect an asteroid
When asteroids hurtle towards Earth in Hollywood films, astronauts often deploy nuclear warheads against them in order to save humanity. Now, scientists have found this strategy could actually help deflect an incoming cosmic impact — not by blowing an asteroid up with a nuke, but by exploding one more than a mile above its surface to shower it with X-ray radiation. As the catastrophic end of the Age of Dinosaurs about 66 million years ago reveals, cosmic impacts can have disastrous effects for life on Earth. “Asteroids aren’t just history…

We finally have a glimpse of the first-ever samples collected from the far side of the moon. The first paper on the samples collected from China’s Chang’e 6 lunar probe reveals that the specimens differ in some ways from those collected from the moon’s near side. Thus, they could provide fresh insights and lead to new theories about the moon and its evolution. China launched its complex, 53-day-long Chang’e 6 lunar far side sample return mission in early May. A lander scooped and drilled for samples inside an area known…

NASA is seeking the public’s help for innovative solutions to help Artemis astronauts navigate in and around the lunar south pole. The Artemis program aims to land humans on the moon for the first time since the Apollo missions managed to achieve the feat over 50 years ago. Astronauts will land near the lunar south pole, where permanently shadowed regions may contain areas of water ice that could be accessed to support future missions to Mars. The Lunar Navigation Challenge, which officially opened on Sept. 4, seeks ideas for a…

Read MoreA ‘primordial’ black hole may zoom through our solar system every decade
If microscopic black holes born a fraction of a second after the Big Bang exist, as some researchers suspect, then at least one may fly through the solar system per decade, generating tiny gravitational distortions that scientists can detect, a new study finds. These findings suggest that if astronomers can discover and confirm the existence of such gravitational disruptions, they may be able to solve the mystery behind the nature of dark matter, the unseen material that many researchers suspect makes up about five-sixths of all matter in the cosmos.…
Read MoreGas and stars ‘stolen’ from galaxy in striking European Southern Observatory photo and video
A galaxy is robbed of its gas and stars in a new image from the European Southern Observatory (ESO). The spiral galaxy, called NGC 3312, lies within a large cluster known as Hydra I. Located over 160 million light-years from Earth, this cluster contains hundreds of galaxies, the largest of which is NGC 3312. Using the ESO’s VLT Survey Telescope (VST) at the Paranal Observatory in the Atacama Desert of northern Chile, astronomers captured an up-close view of the spiral galaxy, which appears to be “spilling its contents into the…
Read MoreCould we turn the sun into a gigantic telescope?
We have some incredibly powerful telescopes that have given us spectacular views of the cosmos and allowed us to look back to the early days of the universe. These observatories, such as the James Webb Space Telescope (JWST), are amazing feats of engineering that have required billions of dollars and decades of work. But what if we could access an even better telescope that already exists? This wouldn’t be a typical telescope. It wouldn’t even come with a lens. But it would be by far the most powerful telescope we’d…

Read MoreSun fires off X-class solar flare, increasing aurora viewing chances into weekend
A parade of solar activity continues to flow from the sun this week, opening up more chances to spot the aurora across the United States this weekend. On Thursday morning (Sept. 12), a sunspot region that has not been numbered yet made its presence known blasting off a X1.3 class solar flare. X-class solar flares are the most powerful of their kind, and are typically followed by a full or partial loss of high frequency (HF) radio signals for sunlit locations on our planet. The energetic eruption, which peaked at…
