Long ago, our universe was without stars. When that first generation ignited, it completely transformed the cosmos, ripping away the veil of neutral gas that had persisted for hundreds of millions of years. This process, called reionization, is largely mysterious to astronomers. But new research is revealing that the smallest of galaxies may have played the biggest of roles.
All Stars die. Some stars go out with a bang. Some stars go out with a big bang — a supernova. And some stars are capable of something so spectacular, so rare, we don't even have a name for it yet.
Sometimes when you want to go out, you want to go out with a bang.
Meet TYC 7037-89-1, a six-star solar system. Astrophysicist Paul M. Sutter explains this stellar surprise discovery.
Something happens once you see the world from a different perspective. It's called the "Overview Effect". But what does that mean?
According to NASA, "A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying." But what happens when a black hole dies?
A vocal minority believes that the moon landing was all an elaborate hoax filmed on a sound stage in Hollywood, but it's no hoax. Here's why...
You would think that objects weighing billions of times the mass of the sun would be easy to find. Alas, it’s rarely that simple.
Okay, stars die in all sorts of interesting and cosmically expressive ways (except the red dwarf stars, who just sort of…stop).
On behalf of Blue Origin, the opportunity of a lifetime is currently being auctioned off: the last seat on New Shepard, heading to space.
ID2299, a galaxy 13.8 billion light years away, died far too young.
In 2018 the Japanese space agency sent the Hayabusa2 mission to the asteroid Ryugu, As a part of that mission, the spacecraft blasted material off the surface of the asteroid, put it in a bottle, and sent it back to Earth. Two years later that sample landed in the western deserts of Australia.
Exoplanets are planets orbiting stars outside the solar system, and every month seems to bring in a new batch of weird, wild, and wonderful worlds.
Things are getting a little crowded at the red planet.
