This Image Might Show Exomoons Forming! | SciShow News

Thanks to CuriosityStream for supporting this episode of SciShow Space! Go to to learn more. [♪ INTRO] Every now and then, astronomers give us an image of space that just sort of makes our jaws drop. And another one of those images was published last week in the Astrophysical Journal Letters. This is an image of a […]

Something Is Creating and Removing Oxygen on Mars | SciShow News

{♫Intro♫} The Curiosity rover has been hard at work on Mars—both finding mysteries and trying to solve them. This is a detective story! Last year it discovered that levels of methane in the atmosphere were mysteriously changing. And now our trusty rover has thrown us for a loop again: changing levels of oxygen gas. Scientists published their results […]

We’ve Never Seen a Pulsar Explode Like This | SciShow News

[♪ INTRO] Human space exploration is all the rage these days, with NASA and other organizations racing to get astronauts on the Moon and beyond. But one UK-based startup is dreaming of something a little different. They want to populate the Moon with robots. And instead of building a traditional, multi-wheeled rover, they’re designing ones with legs. The […]

Voyager 2’s Notes from Interstellar Space | SciShow News

[♪ INTRO] Sending a spacecraft to explore far-off places in the solar system is cool. But you know what’s even cooler? Sending spacecraft to explore outside the solar system. It’s new terrain for human-made objects, and we’ve only done it twice. But in a series of papers published this week in the journal Nature Astronomy, scientists shared the […]

Giant Stars Don’t Follow the Rules | SciShow News

[♪ INTRO] At first glance, the universe can seem pretty straightforward, like when it comes to dying stars. According to the standard story, which matches most of what we see around us, small stars die relatively quietly, while big ones explode as supernovas. But while that sounds neat and tidy and all, the reality is, big stars are […]

Why Physics Can’t Totally Explain the Universe’s Expansion | SciShow News

{ ♪ INTRO ♪ } Since the moment it began, the universe has been expanding. It took humanity a while to figure that out, but over the last century, astronomers have gotten pretty good at calculating how fast it’s happening and how that speed has changed over the past 14 billion years. Right now, there are two main […]

Does Dark Matter BREAK Physics? | Space Time | PBS Digital Studios

[MUSIC PLAYING] Dark matter literally binds the galaxy together. But there’s a problem. Nobody knows what dark matter is. My name is Matt and this is “SpaceTime.” Physics has a problem. The Milky Way galaxy is spinning so fast that it should be scattering its stars into the void. Based on the amount of binding gravity that we […]

Radio Saturn Wobbles and Sirens

Cassini has been in orbit around Saturn for more than six years. And new data tells scientists that the sixth planet from the sun is weirder than we’ve even imagined. Ever since we arrived, Cassini has been measuring radio waves called ‘Saturn kilometric radiation.’ Cassini’s radio and plasma wave instrument recently determined that the variation in radio waves […]

Planet 9 Could Be a Black Hole?! | SciShow News

[♩INTRO] In 2016, two Caltech astronomers proposed that our solar system is home to nine planets. And no, they didn’t reclassify Pluto. Instead, they found evidence for a hypothetical Neptune-sized planet at least forty billion kilometers from the Sun far enough that it would take fifteen thousand years for it to complete one orbit. In the last three […]
