There might be a galaxy made mostly of dark matter orbiting the Milky Way!

How did the periodic table of elements revolutionize our understanding of the world? What scientists contributed to the table we have today? Eric Rosado discusses the key people and discoveries that have molded our understanding of...

All the complexity in the universe ultimately owes its existence to one of the simplest materials possible: molecular hydrogen. And not only did this molecule play a huge role in building the universe as we know it, today, it also helps...

The Kepler space telescope found a star that randomly gets really dim, and some people are suggesting the star's being blocked by a huge alien structure. It's probably not aliens, though.

This week in news, scientists have found a galaxy coming to a smashing end, and a neutron star that's... The most.

I'm not saying it's aliens....and it's probably not aliens. Also, an update about the most recent SpaceX explosion!

Our Milky Way Galaxy once dined on the Sausage Galaxy, and Jupiter's auroras seem to be heavily influenced by one of its moons. It's a galaxy-eat-galaxy kind of universe out there!

Computer models are helping scientists on the hunt for small black holes and new data is giving us a better understanding of the universe’s largest explosions.

After Hubble and Webb, what's the future of space telescopes? Two ideas in planning stages right now involve the space-age versions of umbrellas and glitter.

We’ve seen a distant star from another galaxy far, far away, and the Milky Way is growing, thanks to baby stars born in the outer edge of our galaxy’s disk.

Get your eclipse glasses ready because the a total solar eclipse is an astronomical event unlike any other.

Gravitational lensing has given us a look at a galaxy in the very, very distant cosmic past using x-ray light, and NASA finally got its ICON mission off the ground!

Black holes are already pretty extreme, but some stand out among their peers, driving cosmic engines that outshines the rest of the galaxy and even serving as birth control for stars!

We’ve created simulations to recreate the difference in time it takes for the Sun’s equator and poles to complete rotations, and the way we’ve solved is a bit surprising. And it looks like the Milky Way may not be great at mixing metals,...

Sometimes science news is less about stuff that actually happened, as much as it is about people going "PAY ATTENTION TO ME" and space news is no exception. In fact this week there was probably as much hype as real news, all in the name...

The exploding “cow” around 200 million light-years away is running astronomers for a loop, but if it is what some hypothesize, we are witnessing a first for astronomy! Meanwhile, we got photographic evidence of a planet orbiting a binary...

When we say a planet is habitable, we aren't REALLY saying what we think we are saying. 'Habitable' means something else. Is Kepler 186f habitable, in the true sense of the word? And if not, what other planets should we be looking at?...

This video is about the differences between the corpses or final degenerate dense star forms that dead stars take: black holes, neutron stars, and white dwarfs. The main distinguishing features between them are the mass cutoffs...

The Universe is expanding which means distant galaxies are only moving farther away from us. So in the farthest future, will our night sky be empty?

In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow.

Fermi bubbles are made up of gamma rays, but where they came from is still up for debate. Did they come from a star-forming region, or the black hole at the middle of our galaxy?

It’s been a great week for space explosions! Astronomers learned more about the mechanism that causes novas by looking at the nova V906 Carinae, and the brightest supernova ever recorded shed some new light on pulsation pair-instability.

Scientists have found a galaxy with almost no dark matter and we have finally solved the Leading Arm mystery!

Megan Washington is one of Australia's premier singer/songwriters. And, since childhood, she has had a stutter. In this bold and personal talk, she reveals how she copes with this speech impediment—from avoiding the letter combination...
