Take a look through this cosmic lens 

Gravitational lensing is like nature’s magnifying glass. It can warp or magnify the appearance of distant galaxies, seen as arcs of light in this #HubbleFriday image!

It takes a team!
 
Go behind the scenes to Hubble's control center, where the Hubble team completed a successful switch to backup hardware on the telescope last week.

Thanks to them, Hubble is back to work, furthering our understanding of the universe: https://t.co/9Sdtm28dGz https://t.co/PdQTFrEL51

This photo was taken by @NASAHubble #OTD in 2006 of Protostar IRAS 20324+4057 which is in the process of growing from the dust and gas around it. Surrounding stars are blasting it with UV radiation, pushing the gas and dust into a caterpillar-like shape. https://t.co/q1kiNho5qr

The aftermath of an intergalactic collision

This #HubbleClassic features a “bird’s eye view” of two interacting galaxies in NGC 6745, around 200 million light-years away.

Gas and dust clouds collide, with high velocities triggering star formation: https://t.co/0Pp3uUbWwS https://t.co/00ZMDCxedu

The universe at your fingertips. 

With Hubble’s SkyMap, you can explore the Milky Way to find a selection of galaxies, stars, nebulae, and more. Plus, find a stunning Hubble image of each object: https://t.co/vJJItOV8Od

“That’s one of the benefits of a program that’s been running for over 30 years: the incredible amount of experience and expertise.”

After Hubble ran into a payload computer issue on June 13, team members new and old worked to recover the telescope: https://t.co/QEUYEPhOio https://t.co/nS4nzxVlFF

Hubble's back! 

After the Hubble team successfully turned on backup hardware aboard the telescope, the observatory got back to work over the weekend and took these galaxy snapshots.

RT @Astro_Megan: It’s official: Between @Space_Station and @NASAHubble Servicing Mission-4, I have now spent 100 days of my life in Low Earth Orbit! Thanks to my outstanding family and ground support for making it possible, and to all my #SpaceBrothers for making it fun. https://t.co/rwpHHsZJPx

All instruments on the Hubble Space Telescope are now in operational status, and science data is once again being collected to further our understanding of the universe.  https://t.co/1pskum8dXY

Slight change of plans! We’re still excited to bring you Deep Field Week, but postponing for a bit. Watch this space for future updates! https://t.co/gbh128Kxk3

The star cluster in this #HubbleFriday image has been known by many names: Dun 538, H 3688, and Pismis 25.

Why? Different astronomers “rediscovered” it multiple times. But these days, it’s known reliably as simply NGC 6380 (NGC = New General Catalogue): https://t.co/nW9XLwZhkT https://t.co/66QVbZuurC

The Hubble Space Telescope backup payload computer was successfully brought online after a successful switch to backup hardware. Following a short checkout period, the science instruments will be brought back to operational status.

Today, NASA began a switch to backup spacecraft hardware on Hubble in response to an ongoing problem with its payload computer. This will be a multi-day event. If successful, the next step will be for science instruments to be brought back into operation. https://t.co/0QEMsatniP

NASA has identified the possible cause of the problem with the payload computer that suspended science operations on June 13 and has approved plans to switch to backup hardware. These activities will begin tomorrow, July 15.

Just in case you were feeling old today...

 This star cluster is about 12 billion years old! Named Caldwell 81, it’s roughly 20,000 light-years from Earth in the constellation Ara.

NASA completed a formal review to assess all operations related to Hubble’s possible switch to backup hardware, which may occur later this week. Investigation into the cause of the payload computer issue is ongoing.

Ever heard of a “flocculent” galaxy? You’re looking at one.

This #HubbleClassic view shows the galaxy NGC 3521, which is classified as a flocculent spiral galaxy because it doesn’t have clearly defined arms, leading to a soft, woolly appearance: https://t.co/yGr3xipnuh https://t.co/vpANXqStuN

RT @Dr_ThomasZ: Recently, @NASAHubble halted operations because of an issue with the payload computer. After many hours of work, Nzinga Tull and her team are more confident they have the resources to resolve the issue.
