  • Scientist suggests possible link between primordial black holes and dark matter
    25 May 2016, 3:20 am
    An intriguing alternative view is that dark matter is made of black holes formed during the first second of our universe's existence, known as primordial black holes. A scientist suggests that this interpretation aligns with our knowledge of cosmic infrared and X-ray background glows and may explain the unexpectedly high masses of merging black holes detected last year.
  • Hubble finds clues to the birth of supermassive black holes
    24 May 2016, 8:49 pm
    Astrophysicists have taken a major step forward in understanding how supermassive black holes formed. Using data from Hubble and two other space telescopes, researchers have found the best evidence yet for the seeds that ultimately grow into these cosmic giants.
  • Astrophysicists detect most luminous diffuse gamma-ray emission from Arp 220
    24 May 2016, 6:34 pm
    Astronomers have detected for the first time the most luminous gamma-ray emission from the merging galaxy Arp 220 -- the nearest ultraluminous infrared galaxy to Earth reveals the hidden extreme energetic processes in galaxies. Luminous infrared galaxies and ultraluminous infrared galaxies are the most luminous of all galaxies.
  • Astronomers confirm faintest early-universe galaxy ever seen
    23 May 2016, 10:07 pm
    Scientists have detected and confirmed the faintest early-universe galaxy ever, using the W. M. Keck Observatory on the summit on Mauna Kea in Hawaii. The team detected the galaxy as it was 13 billion years ago.
  • 'Fresh' lunar craters discovered
    23 May 2016, 8:12 pm
    Scientists have discovered two geologically young craters -- one 16 million, the other between 75 and 420 million, years old -- in the Moon's darkest regions.
  • Hubble takes Mars portrait near close approach
    19 May 2016, 8:06 pm
    On May 12, 2016, astronomers using NASA's Hubble Space Telescope captured this striking image of Mars, when the planet was 50 million miles from Earth. The photo reveals details as small as 20 miles to 30 miles across. This observation was made just a few days before Mars opposition on May 22, when the sun and Mars will be on exact opposite sides of Earth, and Mars will be 47 million miles from Earth.
  • Cosmic heavy metals help scientists trace the history of galaxies
    19 May 2016, 6:09 pm
    The origin of many of the most precious elements on the periodic table, such as gold, silver and platinum, has perplexed scientists for more than six decades. Recently, however, a team of astrophysicists has provided an answer.
  • Extraterrestrial oceans: Beneath the surface
    19 May 2016, 2:20 pm
    Icy objects in our solar system have large oceans under their surfaces and here life could evolve and flourish, according to recent research.
  • First evidence of icy comets orbiting a sun-like star
    19 May 2016, 4:06 am
    Astronomers have found the first evidence of comets around a star similar to the sun, providing an opportunity to study what our solar system was like as a 'baby.'
  • Photonics advances allow us to be seen across the universe, with major implications for search for extraterrestrial intelligence
    18 May 2016, 6:55 pm
    Looking up at the night sky -- expansive and seemingly endless, stars and constellations blinking and glimmering like jewels just out of reach -- it's impossible not to wonder: Are we alone? For many of us, the notion of intelligent life on other planets is as captivating as ideas come. Maybe in some other star system, maybe a billion light years away, there's a civilization like ours asking the exact same question. Imagine if we sent up a visible signal that could eventually be seen across the entire universe. Imagine if another civilization did the same.
