Multicolor infrared (red/green/blue=24/8/4 micro-meter, SPITZER Space Telescope, Wachter et al., 2007) and radio (VLA, Kim & Koo 2002) image of the environment of SGR 1806-20 / C1 1806-20 (located at the red spot with the black cross). Cyan contours represent radio emission. The dotted line indicates the radio nebula G10.0−0.3 as given by Kulkarni et al. (1994). The white contours illustrate the TeV gamma ray source shown in Fig. 3. (credit: H.E.S.S. collaboration)
The big band theory. - The big bang theory is a theory on how the universe was created.Before the big bang was nothing at all, it was just a very hot and dense expanse and then it all just exploded in a massive explosion, after that the universe cooled down and was able to convert energy into subatomic particles like protons, neutrons and electrons. While neutrons and protons combined to create the first atomic nuclei, just minutes after the Explosion, it took thousands of years for the…

Scientists compared the ultraviolet imagery from a Hubble camera (on the left) with UV spectra from a Hubble spectrograph (pseudo-image on the right) to identify and study specific stars within the cluster.
pictures-of-space: “ A Lopsided Lynx This galaxy, known as NGC resides 25 million light-years away in the constellation of Lynx. NGC 2337 is an irregular galaxy, meaning that it — along with a quarter of all galaxies in the Universe — lacks a.
