In honor of the spookiest time of year, let's take a look at the spookiest-named things in the cosmos.

We’ve talked a lot about black holes, but there are other kinds of space holes out there that deserve some time in the spotlight!

Mars’s moon, Phobos, is striped with grooves all across its surface. But if one theory about where they came from is true, does that mean this moon might be on its way out?

The Sun isn’t the only celestial body in the solar system to boast spots of its own. Mercury, too, has its fair share, and they’re worth wondering about.

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.

You're familiar with the Moon, but it's not only our moon, depending on your point of view.

2022 was a pretty exciting year for space science, but what news might we expect in the coming year?

We usually only get to use our sense of sight in exploring the universe, but that hasn’t prevented scientists from trying to listen in.

The James Webb Space Telescope isn't just for finding Pinterest worthy pictures, we're finding some amazing details in the sometimes blurry background photos.

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...

Saturn's moons Janus and Epimetheus were once thought to be the same moon. It turns out they're dance partners.<br/>

Space is pretty deadly. But is it so deadly that we’re effectively imprisoned in our solar system forever? Many have said so, but a few have actually figured it out.

In astronomy we talk about billions of years like it’s no big deal. But how can we be sure about timescales so far beyond the capacity for human intuition? Our discovery of what we now call deep time is very recent - as recent as our...

Einstein once asked whether “the moon exists only when I look at it?". It was rhetorical objection to the idea that measurement in quantum mechanics causes reality to become real. But there was a time when the moon didn’t exist, and then...

If you rank the most habitable places in our solar system Venus lands pretty low, with surface temperatures hot enough to melt lead and sulphuric acid rain. And yet it may have just jumped to the front of the pack. In fact, we may have...

Our solar system is a tiny bubble of habitability suspended in a vast universe that mostly wants to kill us. In fact, a good fraction of our own galaxy turns out to be utterly uninhabitable, even for sun—like stellar systems. Is this why...

The great physicist Hermann Weyl once said: "My work always tried to unite the true with the beautiful, but when I had to choose one or the other, I usually chose the beautiful." But is this actually good advice for doing physics?

With the global pandemic of Covid 19 still encompassing the world, we are generally not big fans of viruses right now. But we sure are thinking about them a lot. That’s right, even astrophysicists are pondering these bizarre little...

The Kepler telescope recently noticed a strange partial eclipse that some have speculated could be a Dyson Sphere. Are Dyson Sphere's possible? Are they practical? What other alternatives to futuristic energy capture do we have to choose...

What do we do to protect ourselves from extinction level events? And what if some of those events are unavoidable? Can we survive adrift in space? Find out in this episode of Space Time.

We already have the technology to bring humans safely to Mars and set up small settlements - or at least could do within a generation. But those settlements will need to be cocooned - shielded against the deadly cold, intense radiation,...

Mercury, Venus, and Mars are all super low on water – so where did ours come from and why do we have so much of it? We think our water came from a few unlikely sources: meteorites, space dust, and even the sun.

Carl Sagan’s famous words: “We are star stuff” refers to a mind-blowing idea – that most atomic nuclei in our bodies were created in the nuclear furnace and the explosive deaths of stars that lived in the ancient universe. In recent...

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.
