APOD: 21st Century M101 (2016 Jan 22)

Post by APOD Robot » Fri Jan 22, 2016 5:12 am

Image 21st Century M101

Explanation: One of the last entries in Charles Messier's famous catalog, big, beautiful spiral galaxy M101 is definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way Galaxy. M101 was also one of the original spiral nebulae observed with Lord Rosse's large 19th century telescope, the Leviathan of Parsontown. In contrast, this multiwavelength view of the large island universe is a composite of images recorded by space-based telescopes in the 21st century. Color coded from X-rays to infrared wavelengths (high to low energies), the image data was taken from the Chandra X-ray Observatory (purple), the Galaxy Evolution Explorer (blue), Hubble Space Telescope (yellow), and the Spitzer Space Telescope (red). While the X-ray data trace the location of multimillion degree gas around M101's exploded stars and neutron star and black hole binary star systems, the lower energy data follow the stars and dust that define M101's grand spiral arms. Also known as the Pinwheel Galaxy, M101 lies within the boundaries of the northern constellation Ursa Major, about 25 million light-years away.

(Editor's Note: Original APOD retracted on January 25.)

Know the quiet place within your heart and touch the rainbow of possibility; be
alive to the gentle breeze of communication, and please stop being such a jerk.

Just in case someone is looking for discussion on the original Post for this day, titled "International Space Station Transits Saturn", it's at http://asterisk.apod.com/viewtopic.php?f=9&t=35581

If this happens to APOD again, may we please have a clearer explanation of what is going on?
I have just wasted ten minutes of my life, trying to work it out. I first read it on my phone, not a good place for research, and had to return to it when I could sit down at the PC. I had to follow every link and read them, to no avail, until the last - thank you, aildoux!

AFAICT, the APOD for the 22nd Jan 2106 was contested as not genuine, and withdrawn. The picture of Messier 101 the Pinwheel, was put up in its place.

This may be obvious to those who spend a lot of time here, but the gnomic "editorial note" left a lot unsaid.
Even more interesting than that excellent galaxy pic would be a forensic account of how the original APOD's falsity was revealed.

You've got it right, and you also probably got off easy with the ten minutes of your life wasted. A lot of us spent a lot more time on it.

Does it mean there was originally an image of something different on this day?

There was originally an image of something diffident.

Thanks for the reply, it makes me so sad that this type of thing happens. I remember a few years ago some Brazilian guy faked images of Pluto.
