NASA's Wide-field Infrared Survey Explorer has found the brightest galaxy in the known universe. This galaxy, fondly named WISE J224607.57-052635.0, emits over 300 trillion times more light than our sun.
WASHINGTON, May 21, 2015 /PRNewswire-USNewswire/ -- A remote galaxy shining with the light of more than 300 trillion suns has been discovered using data from NASA's Wide-field Infrared Survey
Braaaaaains. A mysterious high-energy X-ray signal detected by NuSTAR could be the sounds of “zombie” stars feeding on the “brains” of nearby stellar companions, according to research published recently in the journal Nature.
A new survey by the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory studied 72 galactic cluster collisions from all different angles and times, revealing that the 85 percent of the universe’s total matter is way weirder than we could ever imagine.
Observational evidence supports a functional link predicted by theory College Park, MD (PRWEB) March 25, 2015 Many nearby galaxies blast huge, wide-angled
What is dark matter? And what is dark energy? These questions are what keep physicists awake late at night.
WASHINGTON, March 4, 2015 /PRNewswire-USNewswire/ -- Using NASA's Chandra X-ray Observatory, astronomers have found that the growth of galaxies containing supermassive black holes can be slowed
Every massive galaxy has a black hole at its center, and the heftier the galaxy, the bigger its black hole. But why are the two related? After all, the black hole is millions of times smaller and less massive than its home galaxy.
Someone dimmed the lights in space. Scientists observe a dimming quasar for the first time ever, and this could lead to a understanding of the mysterious black holes and their lifespans.
X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...
Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
Cygnus X-1 -- Cygnus X-1 (often abbreviated to Cyg X-1) is an X-ray source in the Cygnus constellation considered to be one of the most likely black hole candidates. The optical counterpart (HDE 226868) is a variable 8.9 magnitude star (visible with good binoculars in good observing conditions.) at right ascension 19 h 56.5 min and declination of 35 deg 4 min (for 1950 epoch). Cyg X-1 is a binary star that contains a O9-B0 supergiant (with a surface temperature of 31000 Kelvin) and a...
