Astronomers Think a Meteor Came from Outside the Solar System

When ‘Oumuamua was first detected on October 19th, 2017, astronomers were understandably confused about the nature of this strange object.

Barfing Neutron Stars Reveal Their Inner Guts

We don’t really understand neutron stars. Oh, we know that they are – they’re the leftover remnants of some of the most massive stars in the universe – but revealing their inner workings is a little bit tricky, because the physics keeping them alive is only poorly understood. But every once in a while two …

What Will the James Webb Space Telescope See? A Whole Bunch of Dust, That’s What

When it comes to the first galaxies, the James Webb Space Telescope will attempt to understand the formation of those galaxies and their link to the underlying dark matter. In case you didn’t know, most of the matter in our universe is invisible (a.k.a. “dark”), but its gravity binds everything together, including galaxies. So by …

The First Molecule that was Possible in the Universe has been Seen in Space

It takes a rich and diverse set of complex molecules for things like stars, galaxies, planets and lifeforms like us to exist. But before humans and all the complex molecules we’re made of could exist, there had to be that first primordial molecule that started a long chain of chemical events that led to everything …
