Comets are famous for having space tails. But they're not the only ones! Asteroids, planets, and even stars can rock tails of their own.

The James Webb Space Telescope is the most ambitious space observatory ever launched, and nobody hyped it more than us. So is it putting in work? Oh, boy, yes. Yes it is.

Even if we find an earth-sized exoplanet, how can we be so sure that we're looking at earth 2.0? It might come down to how fast it's spinning.

Earth and the other seven planets in our solar system have only one star: the Sun. Years ago, astronomers found the first exoplanet that had two stars. They also found one with three stars. And four. Just how many stars can one planet...

Neutron stars, are some of the most extreme phenomenon in the universe. It's doubly so for a subset known as pulsars. Some are spinning so fast, and are so massive, that astronomers aren't entirely sure how they got to be that way. One...

If we lived light years from Earth, how would we know there’s life here? Let’s take a look at the search for extraterrestrial life on habitable exoplanets, and discover what biosignatures would show someone else that we’re here.

Hunting for rogue planets is like hunting for an invisible needle in a haystack. But we're getting a much clearer view thanks to gravitational microlensing surveys. And it looks like there are a LOT more of them out there than we thought.

Hank talks about astrobiology - the study of and search for life in the universe off Earth. Right now, the field has more questions than answers, but all they all seek to answer that one fundamental query: are we alone in the universe?

We’ve sent thousands of things into space over the years! Many of them just orbit the Earth, and some are flying out past the edges of the Solar System. In this episode, we present our favorite currently active space probes!

Ice is ice, right? Wrong! From the vacuum of deep space to the inside of ice giant planets, ice gets stretched and squished into way more forms than what we find here on Earth.

The Astrophysics Pioneers program is funding four innovative new missions that read like a best-hits album of the most exciting astronomical frontiers: from galaxy evolution and exoplanets, to neutron star mergers and astroparticle physics.

Four rocky inner planets and four gaseous outer planets - makes sense, right? But when astronomers turned their eyes to planets beyond our star system they found out that many systems are set up differently. Why?

Astronomers took advantage of a lunar eclipse to study Earth as if it were an exoplanet, and Mars's Insight lander used seismic data to reveal for the first time boundaries between different layers of Mars.

What exactly is the Thirty Meter Telescope, and why is the proposed location in Hawai'i such a conflict?

Scientists may have found the light from two merging black holes, and a gas giant, without the gas.

The source of earth's water is something of a mystery, and some scientists are starting to think that the sun might have provided the special ingredients to help.

Hank talks about astrobiology - the study of and search for life in the universe off Earth. Right now, the field has more questions than answers, but all they all seek to answer that one fundamental query: are we alone in the universe?

It’s not easy to find active plate tectonics on other worlds, but doing so may bring us one step closer to finding a planet that can support life.

Unfortunately, time machines don't exist, but there are other ways to learn about our sun's past.

Hank dishes out updates on the mutant flu virus and the James Webb Space Telescope, and gives us some new bits about new exoplanets, secret space planes, and a study that shows that music evolves according to Darwin's rules.

Life on Earth depends on the steady nature of our star, and an international team of scientists searched thousands of other stars to try to find out if the sun has always been as consistent as it is now. And According to a study...

Astronomers may have figured out some cool geology on Pluto, and Barnard's star is back in the running for having a planet!

Astrophysicists have discovered an exoplanet that lost its atmosphere, but then, somehow, grew it back! Also, astronomers used satellite data to find a magnetic hurricane above the north pole that we almost missed!

Exoplanets are being discovered in the habitable zone to sustain life as we know it. Could water be found on the closest exoplanet to us?
