This Hubble image might look like it got marked up with white pen, but it's actually a photobombing asteroid's trail as it moves through Hubble's field-of-view!

These sorts of observations help get a census of the asteroid population in our solar system: go.nasa.gov/3U5gkR7

Good news from our future telescope teammate Nancy Grace Roman Space Telescope – its mirrors passed vision testing!

Roman has a primary mirror the same size as Hubble’s primary mirror, but with a larger field-of-view to gather sweeping survey observations of our universe once it launches in 2027. ⬇️

Hello, Moon! 🌕

#OTD 25 years ago, this Hubble image of our Moon's Copernicus crater was released.

This crater stretches 58 miles wide (93 kilometers)! It was formed when an asteroid over a mile wide slammed into the Moon a billion years ago.

Meet NGC 2146.

At 70 million light-years away, the galaxy in this #HubbleClassic view has an odd feature seen at front-and-center.

One of its spiral arms looks looped in front of the galaxy's core, likely caused by a nearby galaxy's gravitational pull: go.nasa.gov/4d16jgn

Hubble helped show what humans are capable of in space. 🧑‍🚀

Astronauts went on five servicing missions to the telescope, completing complicated spacewalks to repair and upgrade Hubble.

A hundred million light-years away, billions of stars shine in the galaxy IC 4633.

This #HubbleFriday image shows a hub of activity and starbirth – but you might notice in the lower right regions, it's a little obscured by a nebula within our own galaxy: go.nasa.gov/49yFmha

Originally released in celebration of Hubble's 100,000th orbit in 2008, this #HubbleClassic image shows a spectacular scene of starbirth.

About 170,000 light-years away, this nebula is in the Large Magellanic Cloud, a satellite galaxy to our Milky Way: go.nasa.gov/4cMB0pM

The big day is here! ☀️🌕🌎

Say hi to the Hubble team and try our activities at NASA’s #eclipse events in Waco and Dallas, Texas today.

Galactic besties 🌀

The spiral galaxy in this week's #HubbleFriday image is NGC 5996. Beneath it to the left is a smaller companion galaxy called NGC 5994.

Together, this pair is known as Arp 72. They're both about 160 million light-years from Earth: go.nasa.gov/43HJhHn

Spring cleaning? 🧹

Your dust bunnies probably aren't this big.

The opaque, dark knot of gas and dust in this #HubbleClassic view is a Bok globule – a concentration of elements that are responsible for the formation of stars throughout the universe: go.nasa.gov/3vAShBr

Not one but *two* Hubble video series are nominated for #Webbys this year! 🥳

You can vote to choose the Webby People’s Voice Awards – check out all the Hubble and NASA nominations below ⬇️

Meet the 2024 NASA Hubble Fellowship class!

The 24 fellows will receive up to three years of support at a U.S. institution as they pursue independent research in any area of NASA astrophysics.

A field of stars ✨

This week's #HubbleFriday image features the globular star cluster NGC 1651. Globular clusters are roughly spherical groups of stars held together by their mutual gravity.

NGC 1651 is located about 162,000 light-years away: go.nasa.gov/3TYRy6x

Studying the stars 🤩

ULLYSES, the largest Hubble program ever executed, is entering a new era.

After collecting data on ~500 young stars over the span of 3 years, scientists are ready to dig in to learn more on how stars form and impact surroundings: go.nasa.gov/3ISGtNY
