A neutron star merger is an extraordinary event. It features extremely powerful, chaotic magnetic fields that generate extremely energetic photons. Supercomputer simulations show that the extreme gamma-ray photons created in
So why should we expect interstellar comets like 3I/ATLAS and ‘Oumuamua and even to some extent Borisov to be different-different?
The Vera Rubin Observatory (VRO) has barely begun observations and is already wowing us. Images like its Cosmic Treasure Chest have us anticipating even more cosmic glory. And when the
While megastructures are clearly speculative, new research shows that they can (in theory) be built in a way that ensures long-term stability. These findings can provide insight into the properties
NASA telescopes have detected what could be the most distant gamma-ray burst ever detected. A merging pair of neutron stars generated when they merged and exploded as a kilonova. It
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
