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.

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.

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.

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...

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.

All planets with evidence of life please take a step forward. Not so fast, Venus.

Every star you see in the sky, including the sun, will someday die. It’s best to get used to that idea now, before things start to get heavy.

Mars is the ultimate off-the-grid experience--far grittier, far harder, and far… redder than even the most remote locations on planet Earth. Let’s break down some of the challenges that people will have to face in order to survive and thrive on our neighbor in the solar system.

Meet TYC 7037-89-1, a six-star solar system. Astrophysicist Paul M. Sutter explains this stellar surprise discovery.

ID2299, a galaxy 13.8 billion light years away, died far too young.

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?

There was a time, a time long, long ago, before the first stars appeared. The universe was young then and less than a billion years old. But will the fall of light be the end of the universe?

Welcome to the era of precision cosmology…where we’ve managed to very precisely measure everything we don't know about the universe.

Okay, stars die in all sorts of interesting and cosmically expressive ways (except the red dwarf stars, who just sort of…stop).
