In some ways this has been a pretty bad year. but with a President Trump I expect the next few years to be worse. Therefore, let me put up some nice pictures of what the world under Trump might look like. First it’s NGC 6357 (Credit: X-ray: NASA/CXC/PSU/L. Townsley et al; Optical: UKIRT; Infrared: NASA/JPL-Caltech) :
Astronomers call NGC 6357 and other objects like it “HII” (pronounced “H-two”) regions. An HII region is created when the radiation from hot, young stars strips away the electrons from neutral hydrogen atoms in the surrounding gas to form clouds of ionized hydrogen, which is denoted scientifically as “HII”.
Donald Trump will certainly strip some pretty important things from our country. Anyway, it’s a pretty picture:
Next is megamaser (Credit: ESA/Hubble & NASA, Acknowledgement: Judy Schmidt (geckzilla)):
Megamasers are intensely bright, around 100 million times brighter than the masers found in galaxies like the Milky Way. The entire galaxy essentially acts as an astronomical laser that beams out microwave emission rather than visible light (hence the ‘m’ replacing the ‘l’).
Happy New Year.
