The 1572 Tycho supernova, as seen by Chandra
Cool image time! The Chandra science team has released a beautiful X-ray image of the remnant from the 1572 supernova first discovered by astronomer Tycho Brahe.
As with many supernova remnants, the Tycho supernova remnant, as it’s known today (or “Tycho,” for short), glows brightly in X-ray light because shock waves — similar to sonic booms from supersonic aircraft — generated by the stellar explosion heat the stellar debris up to millions of degrees. In its two decades of operation, NASA’s Chandra X-ray Observatory has captured unparalleled X-ray images of many supernova remnants.
Chandra reveals an intriguing pattern of bright clumps and fainter areas in Tycho. What caused this thicket of knots in the aftermath of this explosion? Did the explosion itself cause this clumpiness?
The image to the right, reduced to post here, is a composite of both X-ray (the remnant) and optical light (the background stars).
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I thought I was looking at a electron microscope shot of a virus !
Bob,
The Harvard site has the image in time-lapse that looks amazing: https://chandra.harvard.edu/photo/2016/tycho/
You can see the entire mass bulging towards the camera in relation to the background stars. I’m going back in and rummage around for some high-res shots. It’s an amazing universe that we’re spinning through!
Tom
Tom: Incredible. As much as I try, it is impossible to keep up with all the grand stuff now being discovered in space and astronomy. Thank you.
Amazing.
And the heavens proclaim !
Was it not Albert Einstein who encouraged us “to look to the heavens and learn from them” ?
