In the span of a human lifetime, much of the Universe seems unchanging. But that’s an illusion; things are always changing, and that fact can make galaxies and the clusters they reside in very unruly places due to mergers and collisions.

A nearby supernova could reveal the secret lives of ghostly neutrinos. Here's how.
By modeling the neutrinos from a supernova as an exotic kind of fluid moving at nearly the speed of light, researchers are searching for signs of how neutrinos can interact with each other.
A New Simulation Reveals One Entire Stage of a Star's Life
Nuclear fusion is at the center of stellar evolution. Most of a star’s life is a battle between gravity and nuclear power. While we understand this process on a broad scale, many of the details still elude us. We can’t dive into a star to see its nuclear furnace, so we rely on complex computer simulations. A recent study has made a big step forward by modeling the entire fusion cycle of a single element.

We could be 16 years into a methane-fueled 'termination' event significant enough to end an ice age
Methane emissions from tropical wetlands have been soaring since 2006 and accelerating at the same breakneck speed as they have when Earth's climate flipped from a glacial to an interglacial period.

New Comet P1 Nishimura graces the August dawn sky…but how bright will it get?
The Largest Impact Crater on Earth, 520 km Across, Might Be Hiding Under Australia
Asteroid impacts have arguably killed off more species than almost any other type of disaster since life began on Earth. The most famous of these, the Chicxulub impactor, killed the dinosaurs about 65 million years ago, along with 76% of all species on the planet at the time. But that was by no means the worst disaster; as far as we can tell, it wasn’t even the biggest asteroid. That title currently goes to the Vredefort crater in South Africa. Coming in at over 300 kilometers wide, it was the largest asteroid crater so far found, at least when it was formed about 2 billion years ago. But that might be about to change if a theory from Andrew Glikson and Tony Yeates of New South Wales is correct. They have found what they believe to be the biggest impact crater on Earth since the Late Heavy Bombardment in their own Australian province of New South Wales, and they think it might have caused one of the other five mass extinction events.
