Whether or not you think humans should be announcing our presence to the cosmos, we're doing it, anyway. Both intentionally, and not. And if aliens really do exist, there are several ways they could find us. Here are six of them.

In the past decade, astronomers have discovered interstellar objects, including a 2014 meteor that collided with Earth and 'Oumuamua in 2017. These objects, moving too fast to be bound by the Sun's gravity, have sparked questions about...

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.

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...

There’s one rule on Space Time: It’s never Aliens. But every rule has an exception and this rule is no exception because: It’s never aliens, until it is. So is it aliens yet? And on today’s Space Time we’re going to examine all the best...

Hank tells us three things we probably didn't know about the Voyager 1 spacecraft.

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!

If you thought a hot dog eating contest was impressive to complete, imagine if a black hole entered it! They eat up everything around them, including stars! But they’re not just gluttonous blobs of the universe. Like all things in space,...

Humans have never visited another planet, but we can send special spacecraft called probes to visit them for us! One of those probes, called Voyager 1, has gone deeper into space than any other, and it's sent us some amazing pictures...

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!

In a few million years, we’re going to have to leave Earth if we want to survive. But how long can we actually outrun extinction before the universe becomes uninhabitable to us?

This year, scientists have had a chance to study something pretty mind-boggling: a comet that came from outside of our solar system.

For more than 40 years, the Voyager probes have traveled through space sending back all kinds of fascinating data. But these probes were never meant to send us data forever - so how much longer will these amazing probes last?

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

Hank tells us three things we probably didn't know about the Voyager 1 spacecraft.

Sound can't actually travel through a vacuum like space, but scientists have learned that there's still plenty to hear.

There are still lots of unsolved mystery about carbonados ("black diamonds"), and geologists even think those mystery rocks come from outside of Earth.

We were recently visited by a traveler from outside our solar system. This is the first time we've ever seen an object that came to us from interstellar space. It's name is 'Oumuamua.

SciShow Space explains how different experts define our the boundaries of our solar system and why it's way more complicated (and interesting) than it sounds.

Voyager 1 may be out of our solar system (and 40+ years old) but we're still getting plenty of new data from our interstellar space probe.

Plot often trumps reality when portraying space in movies and, as a result, many films are full of inaccuracies. So how much fiction is actually written into some of our favorite movies? Movies mentioned (and potentially spoiled) in this...

Voyager 2 is the second object to leave our solar system, which means we now have twice as much information about its edges! And scientists have found a record-breaking black hole.

Where does our solar system end, and interstellar space begin, and what is it like there? Satellites and probes like IBEX and Voyager 1 & 2 help us get a better look at our special corner of the galaxy.
