POV: Inside the firing room in 1990 during the launch of Space Shuttle Discovery.

Discovery launched #OTD as part of the STS-31 mission. With five astronauts onboard, its primary goal was to deploy Hubble. The rocket launch itself can be seen through window on the top left.

One of NASA's greatest photographers was launched on this day in 1990!

Space Shuttle Discovery launched with the Hubble Space Telescope, one of the world's largest and most versatile space telescopes, as part of STS-31. Learn about Hubble's origins: go.nasa.gov/4baiTZa

It's been a busy year!

As we mark our launch anniversary today, catch up with Hubble's latest and greatest observations from its past year in orbit.

Take a tour through Hubble's 34th anniversary image with our senior project scientist, Dr. Jennifer Wiseman!

The Little Dumbbell Nebula is an expanding shell of glowing gases around a dying star, located about 3,400 light-years away.

Hubble's bubble! 🫧

This blue 'bubble' surrounding a massive, late-stage star is called a Wolf-Rayet nebula. It was created when speedy stellar winds interacted with the outer layers of hydrogen ejected from the star!

So close, yet so far...

The galaxy and bright star in this #HubbleFriday image might look close together, but they're over 129 million light-years apart! This is a trick of perspective from Hubble's vantage point in low-Earth orbit: go.nasa.gov/4aHgs0a

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.
