The United State announces a stop to testing Anti-Satellite Weapons

The United States Government has declared that it will no longer be performing tests of Anti-Satellite (ASAT) weapons. In a public statement during a visit to the Vandenberg Space Force Base, Vice President Kamala Harris confirmed that this policy has the primary purpose of setting an example to other countries. It represents an important step in the...

Mystery Rocket Crash Site, ISS Independence, Space Nuclear Power

NASA teases JWST images, Rocket Lab launches CAPSTONE, mystery rocket’s crash site found on the Moon, how magnetars are created, ISS gets more independent from Russia and more. If you prefer the news being videoed at you instead of reading them, we’ve got you covered! Here’s a video version of this week’s most important space and astronomy...

The Solar System is Stable for at Least the Next 100,000 Years

It’s nice to have a feel-good story every once in a while, so here’s one to hold off the existential dread: the Earth isn’t likely to get flung off into deep space for at least 100,000 years. In fact, all of the Solar System’s planets are safe for that time frame, so there is good news all around, for you and your favorite planetary body. ...

Most Black Holes Spin Rapidly. This one… Doesn’t

They used to be theoretical, up until the first one was found and confirmed back in the late 20th Century. Now, astronomers find them all over the place. We even have direct...

Tidal Heating Could Make Exomoons Much More Habitable (and Detectable)

Within the Solar System, most of our astrobiological research is aimed at Mars, which is considered to be the next-most habitable body beyond Earth. However, future efforts are aimed at exploring icy satellites in the outer Solar System that could also be habitable (like Europa, Enceladus, Titan, and more). This dichotomy between terrestrial (rocky)...

Red Supergiant Stars Bubble and Froth so Much That Their Position in the Sky Seems to Dance Around

Making a 3D map of our galaxy would be easier if some stars behaved long enough to get good distances to them. However, red supergiants are the frisky kids on the block when it comes to pinning down their exact locations. That’s because they appear to dance around, which makes pinpointing their place in space difficult. That wobble is a feature, not...

This is How You Get Multiple Star Systems

Stars form inside massive clouds of gas and dust called molecular clouds. The Nebular Hypothesis explains how that happens. According to that hypothesis, dense cores inside those clouds of hydrogen collapse due to instability and form stars. The Nebular Hypothesis is much more detailed than that short version, but that’s the basic idea. The problem...

The Case is Building That Colliding Neutron Stars Create Magnetars

Magnetars are some of the most fascinating astronomical objects. One teaspoon of the stuff they are made out of would weigh almost one billion tons, and they have magnetic fields that are hundreds of millions of times more powerful than any magnetic that exists today on Earth. But we don’t know much about how they form. A new paper points to one possible...

A Dying Star’s Last Act was to Destroy all Its Planets

When white dwarfs go wild, their planets suffer through the resulting chaos. The evidence shows up later in and around the dying star’s atmosphere after it gobbles up planetary and cometary debris. That’s the conclusion a team of UCLA astronomers came to after studying the nearby white dwarf G238-44 in great detail. They found a case of cosmic cannibalism...

The Rings of Uranus and Neptune Could Help map Their Interiors

Mapping the interior of the ice giants is difficult, to say the least. Not only are they far away and therefore harder to observe, but their constant ice cover makes it extremely hard to detect what lies underneath. So scientists must devise more ingenious ways to see what’s inside them. A team from the University of Idaho, Cal Tech, Reed College, and...
