I'm obsessed with JWST's series of photos of spiral galaxies. These are helping scientists understand more about these galaxies' origins, evolution, and structure.

Mars Ingenuity was designed to make 5 short flights over 30 days. Instead it made 72 flights over three years on the red planet. Now it's time to say goodbye to the little helicopter that could.

See the swirls of gas and dust in this stellar nursery? JWST snapped this photo of the Large Magellanic Cloud, a galaxy visible from Earth with the unaided eye.

Reminder, if you don’t like video, you can get the text thanks to my *new* newsletter!

JWST took this STUNNING photo of the Crab Nebula, and it's helping scientists learn more about its origins.

At the bottom of the Earth's mantle are features that are thousands of kilometers long, and new research suggests they might be pieces of another planet from the collision that created the moon.

BlueWalker 3 is an extremely bright satellite that's outshining the stars in the night sky, and it's a big problem. Let's talk about why the satellite is so bright, and the bigger issue of satellite pollution for astronomy.

Hubble captured a mysterious bright light between galaxies. What does it mean?

An annular eclipse, or "ring of fire" eclipse, will be visible across parts of North America and South America on October 14, 2023. Here's how to see it.

What's at the center of our galaxy? Meet our friendly neighborhood supermassive black hole!

Hubble observed the globular cluster Terzan 12, returning a stunning photo -- but why are so many of the stars red? Let's dive into what we're seeing!

This JWST photo of Herbig Haro 211 shows us what a sunlike protostar, still in its infancy, looks like. 💫

NASA flew a spacecraft through an explosion on the sun (a coronal mass ejection), and there’s some pretty cool footage of the event.

No spacecraft were harmed in the making of this video!

Is one of the brightest stars in the sky about to explode?

The star Betelgeuse, located in the constellation Orion (and the 10th brightest star in our night sky) has been getting brighter. Is it about to go supernova? Let's dive into what's happening:

NASA announced the crew for Artemis II: Christina Koch, Jeremy Hansen, Victor Glover, and Reed Wiseman. The mission will probably launch in 2025 (it’s currently scheduled for no earlier than November 2024). Here’s a rundown of what the mission will do (and what it won’t, which is land on the moon).

We've known there are volcanoes on Venus for a long time. What we haven't known is whether there are active volcanoes...until now.

Scientists may have discovered volcanic activity on Venus in archival images from a 1990s NASA spacecraft.

Here's why so many people are seeing the Northern Lights

Notice a lot of people talking about the Northern Lights, or Aurora Borealis, today? This is why.

Let’s talk about GEOMAGNETIC STORMS and CORONAL MASS EJECTIONS

This galaxy has a surprising lack of dust. Here’s the deal.
