Using data from ESA’s SMOS satellite, scientists have revealed a surprising shift in the Southern Ocean – surface waters around Antarctica are growing saltier, even as sea ice is diminishing rapidly. This finding defies the norm because melting ice typically freshens ocean surface water.
For generations, humans have gazed at the stars and wondered about the ultimate fate of the Universe. Will it expand forever into the cold emptiness, or meet a more dramatic end? A new study published by physicists from Cornell University, Shanghai Jiao Tong University, and other institutions suggests we may finally have an answer, and it's surprisingly specific.
Galaxies have an overall internal motion called disk velocity. It's how gas, dust, and stars move around the galactic center. It's not a single value but a velocity profile that varies depending on distance from the center. When astronomers spot something in a galaxy that's not moving according to the disk velocity, it catches their attention. That's what happened with M83.
At the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan, the showdown between artificial intelligence and supercomputers has begun. It was here that Riken researchers, along with an international team of colleagues, used machine learning to enhance a simulation of galaxy evolution. The results were compared to direct numerical simulations, like those typically run on supercomputers, and AI won this round! In addition, this approach could shed light on the origins of the Milky Way and the elements essential to life as we know it.
Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this transformation, they may vomit out more stellar material than we knew.
When it comes to star formation, not all galaxies are the same. Some are quenched, meaning they've depleted their star forming gas and form very few new stars. Some, like the Milky Way, are typical and form stars at an average rate. But some are extremely active, and form stars so readily they're called starburst galaxies.
All supernovae are massively energetic stellar explosions. The classic supernovae are massive stars that explode near the end of their lives, leaving behind either a neutron star or a black hole, and a remnant made of expanding gas and dust. But supernovae are not all the same. Some occur in binary systems, and they're called Type 1a supernovae. As it turns out, some of these Type 1a SNe can detonate twice.
