A star-charting spacecraft spotted NASA’s James Webb Space Telescope while both were working in deep space. The European Space Agency’s Gaia mission and the James Webb Space Telescope both orbit around Earth-sun Lagrange point 2, or L2, a gravitationally stable point between the sun and Earth that is roughly 930,000 miles (1.5 million kilometers) from Earth. … Read more
When you’re older, your home town will feel different. That’s true for everybody. But for people living today, the changes will be impossible to ignore. We usually measure climate change in terms of rising temperatures. But scientists say there’s another way of thinking about it: spatial displacement. In a study from 2019, researchers found … Read more
A crescent-shaped crater in Northeast China holds the record as the largest impact crater on Earth that formed in the last 100,000 years. Prior to 2020, the only other impact crater ever discovered in China was found in Xiuyan county of the coastal province of Liaoning, according to a statement from the NASA Earth Observatory. … Read more
It’s been nearly 80 years since two nuclear bombs were detonated over the Japanese cities of Hiroshima and Nagasaki, killing at least 129,000 people, and causing devastating, long-term health effects. To date, those are the only instances of nuclear weapons being used for warfare, but the reality is there are roughly 12,700 warheads remaining in … Read more
Humpback whales can swim as far as 3,700 miles (5,955 kilometers) for the chance to mate, per a new study. Scientists analyzed a database of over 450,000 pictures of whales in the wild to track the animals. They found that some would swim thousands of miles during the mating season. Two distinctive males, which could be … Read more
The Bernardinelli-Bernstein comet, identified in 2021, is officially the biggest comet ever observed. The new record, reported on the preprint website arXiv and now accepted for publication in the journal Astronomy and Astrophysics Letters, bumps the Hale-Bopp comet from the top spot. Hale-Bopp was discovered in 1995 and became visible to the naked eye in 1996; it … Read more
A jaw-dropping lightning megaflash that snaked across three states in the southern US just won a world record. A megaflash is not your standard cloud-to-ground lightning bolt. It’s an enormous electric zigzag that travels from one electrified cloud to the next, almost instantaneously. A big enough thunderstorm system can allow a megaflash to cover hundreds of … Read more
A huge asteroid made its closest approach of the next two centuries Tuesday (Jan. 18), flying quite safely past our planet. Asteroid 7482 (1994 PC1), which is classified as a near-Earth asteroid, only got within five lunar distances of our planet, the equivalent of 1 million miles (1.6 million kilometers). The Virtual Telescope Project, which … Read more
A large, rocky asteroid is going to fly by Earth next week. At 1 kilometer (3,280 feet) long, it’s roughly two and a half times the height of the Empire State Building, and it’s been classed a “Potentially Hazardous Asteroid” due to its size and its regular close visits to our planet. But don’t … Read more
NASA’s James Webb Space Telescope will be more extreme than its famous predecessor in a variety of ways, including its cosmic locale. The $10 billion Webb is considerably bigger, more complex and more powerful than the Hubble Space Telescope, which has been studying the heavens from Earth orbit for more than three decades. And the new … Read more
