Hank clarifies the misconceptions about Chagus disease, discusses a couple of interesting celestial events - one that happened in the past and one that will happen in the distant future, and sheds more light on the benefits of sexual...

Horses have been human companions for thousands of years, and have been essential companions and tools for the development of human culture. So, it makes sense that horses would make their way into our most important stories. Today,...

Considering how massive our universe is, we know the distances to cosmic objects surprisingly well. What tools and clues do scientists use to measure distances that are so enormous they sound like made-up numbers?

Astronomers have finally observed what causes pulsating auroras, and our estimates of the mass of the Andromeda Galaxy have shrunk.

M31N 2008-12a is a rare phenomenon called a recurrent nova, and it may hold the key to understanding the lives and cataclysmic deaths of massive stars.

Linking together the histories of Henrietta Swan Leavitt, Edwin Hubble and Tracy K. Smith, poet and thinker Maria Popova crafts an astonishing story of how humanity came to see the edge of the observable universe. (Followed by an...

How many stars are there in the universe? Are there more stars out there than grains of sand on Earth? Thanks to advanced space telescopes, we've been able to peer farther into deep time and the distant universe than we ever thought...

You're probably used to real galaxies having curves, except not all of them seem to have gotten the memo.

How many stars are there in the universe? This question leads Hank to a couple other questions - How many stars can we see from Earth? How many stars are there in our galaxy? - but the answer to the original question proves elusive.

The Andromeda galaxy is heading straight toward our own Milky Way. The two galaxies will inevitably collide. Will that be the very last night sky our solar system witnesses?

Active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter. Galaxies tend not to be loners, but instead exist in smaller groups and larger clusters. Our Milky Way is part of the Local...

How did Hubble discover the expansion of the universe?

NASA’s Nancy Grace Roman Space Telescope will capture the equivalent of 100 high-resolution Hubble images in a single shot, imaging large areas of the sky more than 1,000 times faster than Hubble. In several months,...

All of this Trump and Kim Jong Un drama on earth is mere child's play compared to these ways that our own Universe could wipe us out today!

NASA's Swift satellite has acquired the highest-resolution view of the neighboring spiral galaxy M31. Also known as the Andromeda Galaxy, M31 is the largest and closest such galaxy to our own. It's more than 220,000 light-years across...
