🏠 How's that for curb appeal?

On their way back to Earth last month, our Crew-2 astronauts made a loop around the ISS in their SpaceX Crew Dragon spacecraft, taking a number of pictures which we've now assembled into this new photo album of our orbiting laboratory.

Long-time spacewatchers may be excited to see the new ISS Roll-Out Solar Array on the right side of these photos, a flexible solar panel that could provide a compact source of energy for future space missions. We've been making our home on the International Space Station for more than 20 years, working with countries around the world to study how to live in space while making life better back on Earth.

Who’s ready for the NASA Webb Space Telescope? 🙋‍♀️

Like with Hubble, Webb's launch will usher in a new era of astronomy.

Webb will see beyond Hubble’s infrared vision to expand our perspective to the far reaches of the universe. Working with Webb, Hubble’s visible and ultraviolet vision will complement Webb’s infrared views.

This powerful duo will provide us with staggering cosmic vistas, the likes of which we have only imagined.
Now presenting… NGC 3568!

This HubbleFriday image shows a spectacular galaxy that’s about 57 million light-years from our Milky Way Galaxy in the constellation Centaurus.

Fun fact: In 2014, light from a supernova explosion within NGC 3568 reached Earth. It was discovered by amateur astronomers from the Backyard Observatory Supernova Search in New Zealand.

We can’t wait to explore the universe with NASAwebb!

Hubble has helped pave Webb’s scientific path by making preparatory observations. For example, Hubble surveyed the star cluster Westerlund 2, located about 20,000 light-years away.

One of Webb’s main goals is to observe the birth of stars and protoplanetary systems.

Using Hubble, astronomers looked for binary stars in their earliest stages of development, where they are likely to be surrounded by protoplanetary disks – disks of dense gas and dust that encircle newly formed stars and eventually form into planets.

Westerlund 2 contains many binary stars, and is a prime candidate for future Webb observations.

Webb will launch no earlier than December 24. With its powerful infrared vision, our view of the universe is about to change forever!

But don’t worry – we aren’t going anywhere! With their complementary abilities, Hubble and Webb will work together to give us a more complete understanding of our universe.

Servicing Mission 3A launched in 1999 to “wake up” Hubble after the telescope switched into safe mode following the failures of four of its six gyroscopes.

Hubble 🤝 Chandra

This image of the Jewel Bug Nebula contains both visible light data from Hubble and X-ray data from NASA ChandraXray, giving us a more complete (and stunning!) understanding of this cosmic object.

Ten years ago, Hubble showed us this “snow angel” 😇

Called S106, this star-forming region is about 2,000 light-years away and resides in a relatively isolated part of our Milky Way Galaxy.

This Hubble Classic view stretches several light-years across!

Journey to the center of the Milky Way!

Hubble helped detect evidence that our galaxy’s central black hole has a "mini-jet" that ejects superheated material. It periodically “hiccups” as stars and gas clouds fall into it!

This image of our galactic center features Hubble data. Find out more at the link in our bio!

🔴 Red Bubble 🔴

The nebula SNR 0509-67.5 (nicknamed the Red Bubble) is the result of a supernova explosion of a star!

This sphere of gas is the result of gas that’s being shocked by the expanding blast wave of the supernova. The Red Bubble is 23 light-years across and is expanding at a rate of about 11 million miles per hour (5,000 kilometers per second)!

Happy #InternationalMountainDay!

Hubble viewed its very own celestial "Mystic Mountain" in the Carina Nebula. This three-light-year-tall pillar of gas and dust is located about 7,500 light-years away from us.

This infrared view shows reveals stars behind the gaseous veil of the nebula's wall of hydrogen, laced with dust. The foreground pillar becomes semi-transparent because infrared light from background stars penetrates through much of the dust.

And if you haven't heard: The NASA Webb Space Telescope launches later this month, and with its powerful infrared capabilities, we’ll see spectacular infrared views of our universe!

🌌 Happy Hubble Friday!

This week’s image shows the spiral galaxy UGC 11537, which lies about 230 million light-years away.

The two foreground stars are making a cosmic photobomb, as they’re actually within our galaxy, the Milky Way. Because UGC 11537 lies close to the plane of the Milky Way, these two stars crept into the image.

Hubble captured this view in visible and infrared light using Wide Field Camera 3. Find out more at the link in our bio!

Celestial lightsaber? 👀

Not quite. This is a Herbig-Haro object, which forms when a newborn star shoots twin jets out into space – sort of like a birth announcement to the universe!

Called HH24, this object is located inside a turbulent starbirth region known as the Orion B molecular cloud complex, located 1,350 light-years away.

Why can you see the Moon during the day? 🌕

Easy, because it’s there! It may seem odd to look up at the daytime sky and see the Moon but it’s perfectly natural. Planetary geologist Sarah Noble breaks it down so you know when to look up.
Nestled atop an Arianespace Ariane 5 rocket, the James Webb Space Telescope rolled out to the launchpad on Dec. 23, 2021, at Europe’s Spaceport in Kourou, French Guiana. Webb will study every phase of the cosmos—from our own solar system to galaxies formed 13.5 billion years ago, just after the Big Bang. A colossal collaboration between NASA, the European Space Agency, and the Canadian Space Agency, Webb will revolutionize our understanding of the universe.

Liftoff is set for Dec. 25 at 7:20 a.m. EST (12:20 UTC)

"The vast loneliness is awe-inspiring, and it makes you realize just what you have back there on Earth." – Jim Lovell

On Dec. 24, 1968, Apollo 8 astronauts Frank Borman, Jim Lovell, and Bill Anders became the first humans to orbit the Moon and the first to witness the Earth rising above the Moon's barren surface. That evening they held a live broadcast from lunar orbit, in which they showed pictures of the Earth and Moon as seen from their spacecraft.

The mission is known for this iconic "Earthrise" image, snapped by Anders, which would give humankind a new perspective on our home planet. Anders has said that despite all the training and preparation for an exploration of the Moon, the astronauts ended up discovering Earth.

Fifty-three years later, we celebrate the moment by looking back on this image.
Goodnight Moon 🌙

A waxing crescent Moon is pictured from the International Space Station during an orbital sunset as it flew 268 miles (431 km) above the Pacific Ocean east of New Zealand.

Above the surface of the Earth, a brilliant sequence of colors roughly denotes several layers of the atmosphere.
Deep oranges and yellows appear in the troposphere, which contains over 80 percent of the mass of the atmosphere and almost all of the water vapor, clouds, and precipitation.

The pink to white region above the clouds appears to be the lower stratosphere; this atmospheric layer generally has few or no clouds. Above the stratosphere, blue layers likely mark the transition between the middle and upper atmosphere as it gradually fades into the blackness of outer space.
Jupiter & Io 🌕

Io is just one of Jupiter’s many moons, but it takes center stage in this Hubble Classic image taken 25 years ago. The black dot on Jupiter’s surface is Io’s shadow!

We hope this view of the Coalsack Nebula is the only coal you’ll get this year.

Also called Caldwell 99, this is a dark nebula – a dense cloud of interstellar dust that completely blocks out visible wavelengths of light from objects behind it.
