Some tidally-locked exoplanets might actually be more habitable than astronomers initially thought, and we have some ideas about how Peter Pan disks can last so much longer than other protoplanetary disks.

In this short talk from TED U 2009, Brian Cox shares what's new with the CERN supercollider. He covers the repairs now underway and what the future holds for the largest science experiment ever attempted.

Big Data is everywhere — even the skies. In an informative talk, astronomer Andrew Connolly shows how large amounts of data are being collected about our universe, recording it in its ever-changing moods. Just how do scientists capture...

All telescopes work by gathering light from the stars, but one held the crown for square footage for collecting that light for 53 years. The amazing Arecibo.

Most rocky planets have pretty consistent surface features, with a fairly even mix of mountains and basins in each hemisphere. This is NOT the case on Mars! What do scientists know about this mystery?

The auroras are one of earth's most dazzling displays, but thanks to Joan Feynman we know that they're so much more.

Gardening doesn't need to be a hobby just here on Earth. In fact, it might help life outside of Earth quite a bit to take that pastime to the stars.

We've been sending people to space since the '60s, and we're just now starting to learn what that does to their brains.

Astronomer Dr. Jane Rigby challenges the limits of the naked eye. Having influenced most famous telescopes that come to mind, her work is defined by breaking boundaries both physical and beyond.

About once every century, a massive star somewhere in our galaxy runs out of fuel. No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova. The...

To repeat the space time maxim: it's never aliens .... until it is. So let's talk about 'oumuamua.

SETI researcher Seth Shostak bets that we will find extraterrestrial life in the next twenty-four years, or he'll buy you a cup of coffee. He explains why new technologies and the laws of probability make the breakthrough so likely --...

Hank reports on the discovery by NASA scientists of the most distant, oldest galaxy ever observed.

Scientists are discovering new objects in the solar system all the time. Most of these are small asteroids or icy bodies, but researchers recently spotted something unexpectedly huge heading our way.

A launch window that only happens every 26 months means it’s the perfect time to head to Mars! The United Arab Emirates, China, and the United States all took advantage of this excellent timing.

For 13 years, the Cassini probe circled Saturn and sent back fascinating data about the seasons of Saturn as it moved through a 29 Earth year Saturnian year.

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...

We could quite possibly catch solar winds as a means for endless energy, and though it sounds like science fiction, we have the materials to do this now.

Today we’re rounding out our planetary tour with ice giants Uranus and Neptune. Both have small rocky cores, thick mantles of ammonia, water, and methane, and atmospheres that make them look greenish and blue. Uranus has a truly weird...

2020 wasn't ALL bad news. This year scientists found ludicrously fast stars, ancient galaxy clusters, and developed a camera that could change how we study the night sky.

NASA’s Mars 2020 mission has successfully landed on Mars! But it's not alone! This week we discuss not one but three amazing missions to Mars.

NASA's MOXIE successfully creates Oxygen on Mars, and SpaceX's Crew-Dragon successfully returns to the ISS.

Before there was a rover named Perseverance, there was a series of missions that earned that name in their own right.

Is the equinox really when day = night, or is that a myth?
