A team of astrophysicists and astronomers, led by Dr Youjun Lu of the National Astronomical Observatories of China, has found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.
US space agency NASA said on Thursday that its Wide-field Infrared Survey Explorer (WISE) telescope has discovered a remote galaxy that shines with the light of more than 300 trillion suns, making it the most luminous galaxy ever found.
British astronomers have found out the answer to an astronomical mystery -- how do galaxies die? Evidence shows that they are "strangled to death", which occurs after galaxies are cut off from the raw materials needed to make new stars.
After searching 100,000 galaxies for signs of highly advanced extraterrestrial life, a team of scientists using observations from NASA's WISE orbiting observatory has found no evidence of advanced civilizations in them.
