A number of holidays are nearly upon us, and you neighborhood is likely looking a lot brighter at night. Little did you know that up above, the Universe has brightened as well. That's because a pair of Galaxies about 130 million light years away just had a get-together, producing some of the most concentrated super-bright X-ray light emissions ever seen.
The "Eye of Sauron," scientifically known as the nearby NGC 4151 galaxy, is helping scientists to determine the distance to other galaxies tens of millions of light-years away, according to a new study.
That faint blue light that you see up in space isn't a trick of the eye, but the "ghostly glow" of stars from dead galaxies come back to haunt us after being torn to pieces in a sort of cosmic grinder, as captured by NASA's Hubble Space Telescope.
Scientists are focusing on large, star-forming galaxies, whose radiation leaks are shedding light on the beginnings of the Universe as the first stars came into existence, new research says.
Scientists have recently discovered "Laniakea," a massive supercluster of galaxies that is home to our own Milky Way galaxy, shedding light on the boundaries of our own cosmic neighborhood.
