RT @NASAEarth: As @NASAHubble captured new images of storms on Jupiter, @NASA satellites are keeping an eye on an active Atlantic hurricane season. Hurricane #Sally, seen here, dropped up to 16 inches of rain in some areas as it made landfall.

#HubbleFriday The twisting patterns created by the spiral arms of the galaxy NGC 2835 create the illusion of an eye. This is a fitting description, since it’s located near the head of the constellation Hydra, the water snake.

Hubble's new images of Jupiter capture the giant planet’s stormy atmosphere.

The Great Red Spot, a storm big enough to swallow Earth, is still shrinking. Beneath it, “Red Spot Jr.” continues to rage and change color, while a new storm brews in the north: https://t.co/Zg6i8mv61S https://t.co/ySyVuemtcb

How about some #HubbleTrivia? Think about this one:

How many times does Hubble orbit Earth in one day?

Watch the video in the thread to find out if your guess is correct.

#HubbleClassic Normal spiral galaxies appear flat when viewed from the side. But the disk of this unusual edge-on galaxy, called ESO 510-G13, is warped. The distortion is likely caused by the gravitational pull of another galaxy: https://t.co/n4Aq23VEdN https://t.co/eXubxaHRnX

#HubbleFriday Colorful stars pack together in this Hubble image of globular cluster NGC 1805.

This tight grouping of thousands of stars is located near the edge of the Large Magellanic Cloud, a satellite galaxy of our own Milky Way: https://t.co/0DVn92ZWna https://t.co/0Kgp8DOpWG

Everything that makes up stars and planets (and humans!) is only a tiny percentage of the universe’s contents.

Dark matter is the invisible scaffolding of our universe, and a new Hubble study shows we still have much to learn about this strange substance: https://t.co/7A5mQYWUKC https://t.co/Bfcrg0qUj2

RT @NASAGoddard: The blue and orange stars of the faint galaxy named NGC 2188 sparkle in this image taken with @NASAHubble. 

NGC 2188 is estimated to be just half the size of our Milky Way, at 50,000 light-years across, and it is situated in the constellation of Columba. https://t.co/S0aVwc6kWR https://t.co/CotT5JI6ym

Pop quiz! Can you answer this #HubbleTrivia question?

What has Hubble helped to reveal about the expansion of the universe?

Watch the video in the thread to find out if your guess is correct!

#HubbleClassic Galaxies clash & stars form in Stephan's Quintet.

At the center, two galaxies collide as stars burst to life around them. Gravitational tugs on the top-right galaxy spark star formation there. Star birth lights up the top-left galaxy, too: https://t.co/a69eelyqAo https://t.co/DVT2QJzg5A

It's #ReadABookDay!  Hubble’s digital library is full of free, downloadable e-books about our mission and discoveries.

#HubbleFriday From Earth, this galaxy looks like a narrow band of stars.

Like staring at the edge of a plate, we only see the side of the spiral galaxy NGC 2188. Its true shape was identified by studying the distribution and colors of its stars: https://t.co/qjqwzJdRqr https://t.co/CXa5Atjrxf

Who’s up for some #HubbleTrivia? Quiz time!

What does Hubble use to turn itself and point at a target?

Check out the video in the thread to see if your guess is correct.

#HubbleClassic The Southern Pinwheel Galaxy is ablaze with star formation. 

New stars are born in glowing, pink clouds of gas along the edges of the galaxy's dark, spiraling dust lanes. Also called M83, the galaxy is one of the brightest in our night sky: https://t.co/YxjugEc8jr https://t.co/RzisLFxoQc

Since 1990, Hubble’s observations have shaped the way we understand our universe.

#HubbleFriday This Hubble image shows a small section of the Cygnus supernova blast wave.

Between 10,000 and 20,000 years ago, a star about 20 times larger than our Sun went supernova, and its shockwave is still expanding at around 220 miles per second: https://t.co/A0cT2NbsCV https://t.co/PihWeOr7XG

Hubble recently mapped out the halo of gas around the Andromeda Galaxy. It’s too faint to see, but at some points it extends almost halfway to our Milky Way Galaxy!

This illustration shows what we’d see from Earth if the halo was visible to the naked eye: https://t.co/8TbcIhI0lO https://t.co/yoTwNoVFiQ
