Tabby's star is at it again. Could it be aliens this time!? Also, astronomers have discovered a planet with the density of styrofoam!

A private company has been approved to land on the moon!

Astronomers might have finally discovered part of why Tabby's Star acts so strangely and we have some new ideas about what triggers a type Ia supernova.

There are a few ideas about how the universe will end, but a paper published last week suggests that dark energy might eventually rip everything apart!

Scientists have discovered a shard of a planet that survived the death of its star and TESS has found the first direct evidence of an exocomet.

In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from...

The ESA Hipparcos team worked for 20 years on the project, then had to watch as the mission ALMOST failed! But somehow, they turned it around, and today, this little-known mission has totally transformed what we know about space.

From launching a new satellite, to finding diamonds from a lost world, researchers have been hard at work transforming how we think about our planet, the solar system, and the rest of the universe.

The great advances in any science tend to come in sudden leaps. April 25th of 2018 marks the beginning of just such a leap for much of astronomy. In the early hours of the morning, the Gaia mission's second data release dropped. Our...

Scientists have discovered over 5,000 exoplanets in the last few decades, but where are the Exo-Earths?

Hank and Tabetha discuss the mysterious star KIC 8462852 and what might explain its odd behavior (It's probably not an alien megastructure).

It’s been a great week for space explosions! Astronomers learned more about the mechanism that causes novas by looking at the nova V906 Carinae, and the brightest supernova ever recorded shed some new light on pulsation pair-instability.

The edge of everything used to be the edge of the map. But now, thanks to what we know about astrophysics and the universe, the edge of everything might not even exist....

TESS found 3 new exoplanets around a strangely calm m-dwarf star, and it's possible they could be habitable!

So, have you ever wondered why some stars are brighter than others? You might think it's because they're closer to us, but that's not the whole story? In this episode of Crash Course Kids, Sabrina chats about how stars glow and how...

You've know that the Kepler Space Telescope has discovered HUNDREDS of new planets outside our solar system -- but how does it find them? And how do scientists tell the real planets from the celestial fake-outs? It involves a lot of...

SciShow explains why stars do that twinkling that all the kids are singing about, and explains how astronomers can get around it to make observations, and why it can be kinda useful.

How do astronomers make sense out of the vastness of space? How do they study things so far away? Today Phil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth, and from that the...

When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine...

Did you know the moon has a tail? No one did, until 1998, and we've been trying to figure it out ever since.

Pupil outcome: I can describe and apply the rules for voltage in a series circuit. Key learning points: - The voltage of a battery measures the strength with which it can ‘push’ current around a circuit. - The voltage of a component in...

Pupil outcome: I can investigate and explain how voltage affects the brightness of a bulb in a circuit. Key learning points: - Equipment such as a light sensor and data logger can be used to measure and record bulb brightness in lux. -...
