In Science News:
My postdoc, Luca Ighina, just published an analysis of a VERY FASCINATING high-redshift quasar. In short, not only is it radio-loud and ___the X-ray-brightest non-blazar at these redshifts___ it seems like it just might be super-Eddington!
Press release here: https://chandra.si.edu/photo/2025/red6/
And, of course, this is a #ChandraXRay result!

Discovery Awaits! Highlights of the upcoming #ChandraXRay Cycle 27 Science Program. From what makes Jupiter's aurorae glow to counting black holes at the dawn of time, there's lots of science to be excited about for #NASA's Flagship X-ray astrophysics mission!
20 MB PDF: https://cxc.cfa.harvard.edu/target_lists/cycle27/DiscoveryAwaits_Cyc27.pdf(And this is a thing that I, personally, have been working on for a spell, so I'm super excited to see the document released).

A blast from the past.
Check out this X-ray image of the Cassiopeia A supernova remnant, taken by NASA's Einstein Observatory in 1980.

Chandra and Webb, powerful space telescopes, captured a breathtaking image of NGC 602, a cosmic wreath. Webb’s data reveals the wreath’s ring-like outline, while Chandra’s X-ray images illuminate it with the light of young, massive stars.
NGC 602, located on the outskirts of the Small Magellanic Cloud, is about 200,000 light-years away.#SpaceTelescopes #NGC602 #ChandraXray #JamesWebbSpaceTelescope #SmallMagellanicCloud #MilkyWay #Astronomy #GoodNews

"The lowest note is a B-flat, just over 57 octaves below middle C; -- at that pitch, its frequency is 10 million years. The lowest note detectable by humans has a frequency of one-twentieth of a second."
"The sound waves were extracted radially outwards from the supermassive black hole at the center of the Perseus cluster, and played in an anti-clockwise direction from the center, so that we can hear the sounds in all directions from the supermassive black hole at pitches 144 quadrillion and 288 quadrillion times higher than their original frequency."

Let's talk about how We can increase funding for Science programs like:
#NASA, #NASAJPL, #chandraxray#NASAWebb was 7x oversubscribed by scientists in 2024.
Science needs more funding!
Let's make the USA like Star Trek Again.

Fantastic imagery from the various space telescopes. The latest to celebrate the Chandra X-ray telescope's 25th anniversary.
My favourite has always been M16 (the Eagle Nebula) - first was the image from the Hubble, but every iteration since then has still held fascination for me...

#OTD in 1999, the Space Shuttle Columbia lifted off with the heaviest payload ever sent to orbit on the STS -- the #ChandraXRay Observatory. Soon after, Chandra was deployed from the Cargo Bay and boosted to its final orbit via the final Shuttle-based launch of the Inertial Upper Stage (IUS).

At #AAS244 and looking for something to do? Come to our booth and learn about the ongoing science we're doing, our outreach initiatives, how to become an X-ray astronomer (or pretend to be one convincingly!), and grab some great swag!

I have a Love/Hate (mostly Hate) relationship with the Ars Technica comments section, particularly where space is concerned, but it's heartening to see this pro-#ChandraXRay comment sitting on 94 updoots to 0 downdoots on the Hubble Gyro article.
It has been a bit disheartening the past three months to worry about our healthy, productive, and unique mission being terminated abruptly, and so it's good to see the public is getting that message.

In November, we asked the community:
Are there major initiatives for which the capabilities of @ChandraScience are absolutely required to address fundamental questions about our current understanding of the Universe that would represent a crucial missed opportunity if they are not completed during Chandra's lifetime?
The community responded, and we are pleased to announce two Chandra Legacy Programs

That's No Moon!
Well, in this case it is. Back in 2003, #Saturn's moon Titan passed in front of the #CrabNebula. Chandra was on the spot, catching the transit as it happened. Astronomers were able to see the shadow cast by Titan, and used the size of that shadow to measure the extent of Titan's atmosphere.
A great result, demonstrating the power of the Dark Side!

We recently released version 2.1 of the #ChandraXRay Source Catalog!
In short, everything we observed that was released publicly prior to the end of 2021 has been reduced, processed, and made available for easy consumption. With over 400,000 individual sources and covering 730 square degrees, the CSC opens the X-ray sky to all astronomers -- even if you've never looked at an X-ray photon before.

Happy Earth Day! While the #ChandraXRay mission has observed sources near and far, we're one of a very limited set of astronomical observatories that has actively and intentionally observed Earth!
In the winter of 2003-2004, we observed the soft energy X-rays associated with the Northern Lights.

For over two decades, NASA's Chandra X-ray Observatory — humanity's most powerful telescope of its kind — has provided astronomers with a better understanding of the structure and evolution of the universe. But stringent spending caps could force NASA to shut it down. Futurism has more: https://flip.it/OaulLn
#Science #Space #NASA #ChandraXRay -
I just learned that there's a #SaveChandra movement because the Chandra X-ray Observatory might need saving from budget cutting.
-
I just signed the #SaveChandra petition on https://savechandra.org for the reasons below. IMHO: #Chandra is up and running and until a substitute does the same or Chandra dies in orbit, I wouldn't change it (read about the "death spiral" in the link!)
I am not part of any #xray collab, my view is from the outside. But based on my work on #galaxyclusters #ChandraXRay has always been super helpful in understanding odd-looking cases and gaining new insights!
