First, some background. A huge collaboration of astronomers is currently busy spending some hard-won cash to build the world’s largest radio telescope array, called the Square Kilometre Array.

After a truly legendary life, NASA astronaut Michael Collins passed away at the age of 90. Michael was a vital member of the Apollo 11 mission to the moon in 1969 and a pioneer of space exploration.

In 2002, NASA’s orbiting X-ray observatory, the Chandra telescope, mapped out the movements of hot gas in a cluster of galaxies sitting 250 million light-years away.

What if there was another you, somewhere out there, doing all the things you wished you could’ve done? What if there was a multiverse, where all the possibilities and choices of our lives became real? It seems like just another fantasy of science fiction, but it’s closer to reality than you might think.

Does the presence of a stinky gas mean there was once life on Venus?

Want to see what’s behind a black hole? Easy. You just…stare at it. The whole thing is pretty weird to contemplate, but an excellent example of the space-bending (and mind-bending) powers of black holes.

The Crab Nebula sits 6,500 light-years away, and is currently about 11 light-years across. But while it looks pretty from afar, don’t give in to the temptation to visit it up close.

With eclipses, meteor showers, and more, it's a busy month in the night sky this July. Take some time this summer to look up and enjoy these cosmic wonders.

There's something really, really big in the middle of our Milky Way galaxy — one of the largest structures ever observed in the region, in fact.

Through the use of cutting-edge instruments, scientists finally have the opportunity to probe deep beneath the surface and ascertain exactly how the terrestrial planet formed.

Have you always dreamed of going to space? Former NASA astronaut Mike Massimino answers our questions about life at the International Space Station.

This month Jupiter is entering conjunction which means it's the last chance this year to catch a glimpse of the largest planet in our solar system.

A few billionare-backed companies have ambitious goals: launching tens of thousands of communication satellites to provide global high-speed internet access. Elon Musk’s StarLink, Jeff Bezos’ Project Kuiper, One Web, GuoWang, and more are all competing for this lucrative market. In less than a decade, we can expect over 50,000 new satellites to encircle the Earth. That’s about ten times more than are currently active.

Gold had to come to Earth from somewhere, right? So why not outer space?

Meet the Quadrantids. An annual meteor shower that graces the skies right around January 1. This year the shower will be competing with the light of the moon, but if you're lucky you may be able to catch it in the sky this weekend.
