#TBT to this week in 1999 when our Chandra X-ray Observatory lifted off in space shuttle Columbia. Follow @chandraxray to learn about what the mission is observing and how the X-ray light it collects helps us learn about stars, galaxies, black holes, and more.

Hot DOGs in the early universe? Our WISE satellite spied hot dust-obscured galaxies (DOGs) located about 10 billion light-years away. While they are superbright, most of their light is absorbed by thick shrouds of dust.
Dr. Jane Rigby asks research questions of galactic proportions. Literally! 🌌 The@NASAWebbb operations project scientist studies galaxies, especially how they change over time. Learn more about her work and how she's helping

1,730 light-years away, a gas giant planet is so close to its sun that dayside temperatures hit 5,000 degrees F (2,760 C). It also happens to rain sunscreen (titanium oxide).

There are few times in history when we humans look at nature in an entirely new way, & @NASAWebb has already begun to write the next chapter in our cosmic story with its new images. Read more as I reflect on this monumental achievement in my latest blog:

.@JAXA_en’s XRISM spacecraft has completed major milestones! Major components were integrated onto the observatory, including the Resolve & Xtend instruments. These will measure X-rays to help us understand hot and energetic cosmic objects and events.
Today Chandra is studying massive stars in Sagittarius. Nearby in the sky is the Little Gem Nebula — a star shedding its outer layers to form an eye-catching planetary nebula. Roughly half a light-year across, the nebula is enormous compared to its itsy-bitsy central star.

Last week we saw the first exoplanet spectrum from @NASAWebb. Exoplanets are so far away that even our best images reveal little more than bright dots. Spectra (atmospheric data) like those captured by Webb tell us more & allow us to fill in the blanks.

5,060! That's how many planets beyond our solar system we've confirmed so far. Each is a world that may have no parallel in our own solar system, and is trillions of miles/km away ... yet we've found it. #MondayMotivation: What could possibly YOU?

Pulsar IGR J11014 is zooming away from a supernova remnant at over 4 million kilometers per hour — likely kicked to speed by a supernova explosion! The extraordinary jet trailing behind the pulsar stretches for more than 37 light-years.🌠0

In the time it takes you to read this tweet, the expansion of the universe will carry this beautiful spiral galaxy, called UGC 2885, another 49,000 miles away from us. That’s about six Earth diameters. #MondayMotivation

As @NASA missions explore deep space, they will need new @NASASCaN capabilities! Explore the technologies and infrastructure investments that will power mission support well into the future in a new episode of The Invisible Network podcast:
The first images from @NASAWebb are a taste of what's to come. We can't wait to see how new infrared views add to work by @NASAHubble, @chandraxray and other superhero space telescopes covering the cosmos!
Retweeted by NASA Universe
How did we get the data for our first images? Through @NASA’s Deep Space Network! At one million miles away, it takes about five seconds for data to get from Webb to Earth, where it's then sent to our operations center. Right, @NASASCaN? Learn more:

#TBT to this week in 2005 when @JAXA_en’s Suzaku satellite launched bearing X-ray technology developed at @NASA as part of an ongoing collaboration between the two space agencies. For 10 years it studied the universe's hot spots. Check out some highlights:
How is an exploding star like a tape measure? It’s no riddle! Astronomers measure distances to faraway galaxies using a kind of supernova called type Ia. We know how much light they emit, so we can infer their distance by how bright they appear! #NationalTapeMeasureDay
Kim Arcand, a visualization scientist for @chandraxray, geeks out about 3D printing! Kim makes 3D models of exploded stars, stellar nurseries, and black holes, as well as everyday objects like chess pieces, and translates them into 3D prints.
Courtney Lee, the social media lead for @NASARoman, geeks out about video games! From 8-bit classics to the newest VR worlds, Courtney immerses herself in the beautiful pixel universe. Her love for gaming inspired the Roman Space Observer game:
When Chelsea Gohd is not wrapped up in the cosmos at @NASAJPL, she geeks out about music! During her free time, Chelsea is a singer-songwriter and musician who performs and releases indie pop/rock music, often drawing inspiration from the universe.
Barb Mattson is an astrophysicist @NASAGoddard, and she geeks out about hobby board games! Barb enjoys having friends over to play and try new games. Her favorite themes for games include ones about zoos, amusement parks, and especially space!
Faith Vowler, an outreach coordinator for @NASAHubble, geeks out about books! She's continuously buying more shelves to accommodate her growing collection of books — like old and out-of-print mystery books. Faith especially enjoys reading science fiction series.
Marc D. Rayman is a lifelong space enthusiast at @NASAJPL — he geeks out about NASA! Marc has loved space since he was 4 years old. When he was 9, Marc knew he wanted to get a doctorate in physics and work for NASA (but it was a few more years before he did).
Brice Russ, a communications strategist for @NASA, has been a longtime fan of the winter sport curling. He began playing after Team USA won gold at the men’s curling event in 2018. Brice loves the combination of strategy and skill that it requires while playing.
Our colleagues in @NASA astrophysics embrace their geekiness in many different ways. Check out this thread to see some of the cool things they do when they aren’t geeking out about #NASAScience. #EmbraceYourGeeknessDay
