This Is the Biggest Neutron Star Collision We’ve Ever Detected

Gravitational waves resulting from crashing neutron stars have rocked our universe once again. And while you may not have felt it, LIGO sure did. And these gravitational waves are the ripples from a collision of the most massive neutron star pair we have ever witnessed. As you may know, this isn’t LIGO’s first rodeo with […]

Solar Orbiter Will Take Mankind’s First Images of the Sun’s Poles | Countdown to Launch

For the last year, Parker Solar Probe has broken records in speed, collected unprecedented data, and achieved the closest approaches to the sun ever. But none of these insights were detailed images of the sun directly, I mean, if we’re heading to the only star in our planetary system, we want to see it, up […]

How Scientists Are Hunting for the Universe’s First Stars

Looking through a telescope is like looking back in time. Because light has a finite speed limit, the farther away you look, the deeper into the past you see. With radio telescopes we can even see the universe as it was just after the big bang, nearly 13.8 billion years ago. But after that early […]

Get Ready for a New Star in the Night Sky! | SciShow News

{♫Intro♫} Stars explode and die all the time, but they’re so faint and far away that on Earth, we rarely notice. Dying stars we can see with the naked eye are few and far between. Luckily for us, though, three astronomers announced at the American Astronomical Society meeting last week that in not too long, […]

What If We Nuked The Sun?

Imagine, if you will, a world without conflict. Peace reigns supreme across all continents, no more fighting, no more killing. Doesn’t that sound nice? Food and drink for everyone, a place to live for all. Utopian, sure, but it is nice to think about! But there’s one big problem with a world like that: all […]

How Large is the Universe?

The universe has long captivated us with its immense scales of distance and time. How far out does it stretch? Where does it end, and what lies beyond the star fields and the streams of galaxies that extend as far as telescopes can see? These questions are beginning to yield to a series of extraordinary […]

Living on a Generation Ship | Unveiled

Living on a Generation Ship Despite being among the fastest objects ever built by humanity, space shuttles are slow. They’re not nearly powerful enough to truly explore the universe, or even the solar system. The harsh reality is that we may never be able to build the machines needed to practically send people to explore […]

Scientists Just Fit Our Universe in a Box…Wait What

This is the universe in a box. Dark matter, supermassive black holes, galaxies, stars, magnetic fields—our universe, trapped in a cube. Well some of it, anyway. What this really is is our most advanced simulation of the universe and its evolution ever. This very impressive feat is the result of a project called Illustris—The Next […]
