Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their
Anastasios (Andy) Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The star, named Gaia20ehk, was about 11,000 light-years from
Once you start listing the properties of 3I/ATLAS, it becomes clear pretty quickly that this thing is distinctly different from any other comet we’ve ever seen. Here’s just a small
Lunar dust can be a pain—but it’s also literally the ground we will have to traverse if we are ever to have a permanent human settlement on the moon. In
For forty years, a network of telescopes has been listening to the Sun hum and scientists have finally decoded what those sounds reveal about our star’s hidden interior. A new
Multiple mobile phones, dashcams, and dedicated meteor cameras capture a fireball over part of Europe on Sunday night. Thousands of people witnessed it, and the ESA’s Planetary Defence Team is
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this
We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the
One of the Vera Rubin Observatory’s objectives is to detect incoming objects. It’s decade-long Legacy Survey of Space and Time will detect one-meter class objects about to impact Earth and
