Millions of young, blue stars shine brightly in the feather-like arms of the spiral galaxy NGC 2775. 

But at the galaxy’s center lies an unusually large galactic bulge, where almost no star formation occurs, as its gas was converted into stars long ago: https://t.co/w3CjO1RuUz https://t.co/rIqmkwGjst

By looking at light that's taken billions of years to reach us, Hubble is like a time machine. 

Hubble investigates our biggest questions about the cosmos by studying galaxy evolution, black holes, and the expansion of the universe. https://t.co/lGfXHEu7QY

With 30 years of observations, Hubble has taught us a lot about the Milky Way and what's inside.

Hubble has studied stars at every stage of their lives, and examined the atmospheres of other worlds to find out what they're made of. In this video, take a tour of our home galaxy! https://t.co/6tIDygX3zD

We’re thrilled that the Hubble Space Telescope will represent the state of Maryland for the 2020 American Innovation $1 Coin Program! Hubble is managed and operated by @NASAGoddard, located in Maryland. https://t.co/ecbn0ovnTu

Hubble can see deep into space, but it's also made amazing discoveries right here in our solar system! 

Check out what Hubble has seen in our cosmic neighborhood over the past 30 years. Follow along over the next two days for more videos about Hubble's fascinating universe. https://t.co/Dr4UUPAKqE

#HubbleClassic These pictures of Neptune, captured by Hubble 26 years ago, were the clearest views taken of the planet since Voyager 2's flyby in 1989. Hubble found bright clouds in Neptune's atmosphere, but the Great Dark Spot seen by Voyager 2 was gone: https://t.co/2HFOjKXrkn https://t.co/DOGZoKfcow

#HubbleFriday Just like our home galaxy, the Milky Way, the Knife Edge Galaxy is a spiral galaxy. However, its spiral arms aren’t visible in this Hubble image because the galaxy is pictured edge-on, like looking at the rim of a plate: https://t.co/Kco9XlUvav https://t.co/aAIr9sGnN5

In 2017, Hubble saw a huge, wing-shaped shadow being cast on a distant star-forming cloud by a young star’s planet-forming disk.

Now, after observing the shadow again, astronomers report that they see the giant shadow flapping its "wings"! Read more: https://t.co/O4c2lhBgiT https://t.co/J0s51J4o3x

Correction: This planetary nebula is NGC 7027 and was mistakenly referred to as NGC 7072 in the above tweet.

#ICYMI Hubble recently revealed new images of two planetary nebulae, including this colorful picture of the "jewel bug" nebula NGC 7072.

Planetary nebulae are created by dying stars as they shed outer layers of gas. Read and see more from this study: https://t.co/YH7UXFuQJK https://t.co/k6YxPAXFp0

#HubbleClassic In the heart of the Orion Nebula lie four huge, bright stars, known as the Trapezium.

In the 1990s, Hubble viewed the Trapezium in both visible (left) and infrared light (right). Its infrared view revealed hundreds of fainter stars nearby: https://t.co/gmqkVudahn https://t.co/FlHDQYxEli

At the end of their lives, Sun-like stars shed layers of hot gas. To investigate how these ethereal clouds develop, Hubble took new, colorful images of two nearby planetary nebulae, including this picture of the Butterfly Nebula. 🦋

This is gravitational lensing in action.
 
The light of a distant galaxy, seen as red dots near the image’s center, is bent by a galaxy cluster that is between it and Earth. The cluster’s massive gravity warps nearby space, which changes the light’s path: https://t.co/LxfPWxVx7Z https://t.co/3eqUIIUL6Q

Earth isn't the only planet with storms. 

This #HubbleClassic captures an arrowhead-shaped storm on Saturn, as wide as Earth itself, raging on the ringed planet in late 1994: https://t.co/nGBuwCwp2y https://t.co/IgWyyuy0Yr

#HubbleFriday The barred spiral galaxy NGC 2608 is one of many galaxies in this Hubble image.
 
Every faint point of light around NGC 2608 is another distant galaxy. The thousands of galaxies captured here demonstrate the vastness of our universe: https://t.co/sjKXGfDrik https://t.co/va6GdopEOF

#HubbleFriday Globular cluster NGC 6441 is a busy place to be.

About 13,000 light-years from the center of our Milky Way galaxy, this cluster is home to countless stars, along with a few pulsars and a planetary nebula, which form when stars die: https://t.co/2gyXD2iQiE https://t.co/cWelBDQBPv

The early days of our universe are still a mystery.  

Hubble used the light-bending power of a massive galaxy cluster to peer into the early universe, and found something surprising. The first stars and galaxies might've formed sooner than we thought: https://t.co/8kAAQ4qivp https://t.co/P7unpc3yk4

Hubble data from 25 years ago helped this astronomer prove the existence of a newfound planet. Read more from the McDonald Observatory: https://t.co/NwFp26BE3j

At the heart of our Milky Way galaxy is a supermassive black hole. 

About 3.5 million years ago, it unleashed a burst of energy that our very distant hominid ancestors likely saw as ghostly light overhead. Hubble is uncovering clues about this explosion: https://t.co/kSEB8wdbwH https://t.co/WQg7cKuu2B

The Hubble team congratulates @NASA and @SpaceX on a successful #LaunchAmerica! https://t.co/hCSQbgwiST
