Using the James Webb Space Telescope (JWST), astronomers have observed the dramatic “dance” between a supermassive black hole and two satellite galaxies. The observations could help scientists better understand how galaxies and supermassive black holes grew in the early universe. This particular supermassive black hole is feeding on surrounding matter, powering a bright quasar that … Read more

Diagram of H3+ production in Jupiter. Aurora H3+ emission near the magnetic poles is caused by precipitating electrons, and extreme UV radiation from the sun irradiates the day side and dominates H3+ production near the equator. No significant H3+ is expected at low latitudes on the nightside, making it an ideal DM signal area. Credit: … Read more
Strange behavior in a huge cluster of merging galaxies could be explained if dark matter, the universe’s most mysterious stuff, can collide with itself. However, the most favored model of cosmology at the moment is the Cold Dark Matter (CDM) model – and it suggests that dark matter, which is effectively invisible because it does … Read more
