Simulations reveal galaxy clusters details

Inspired by the science fiction of the spacefaring Romulans of Star Trek, astrophysicists have used XSEDE-allocated supercomputers to develop cosmological computer simulations called RomulusC, where the 'C' stands for galaxy ...

Black hole or newborn stars? SOFIA finds galactic puzzle

Universities Space Research Association (USRA) today announced that scientists on NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) found a strange black hole that is changing its galactic surroundings in a ...

What ionized the universe?

The sparsely distributed hot gas that exists in the space between galaxies, the intergalactic medium, is ionized. The question is, how? Astronomers know that once the early universe expanded and cooled enough, hydrogen (its ...

Giant ionized gas nebula found by astronomers

(Phys.org)—A group of astronomers has discovered a giant nebula of ionized gas extending over 300,000 light years. This nebula turns out to be associated with the quasar dubbed the "Teacup." The finding was presented November ...

Image: Hubble gazes at long-dead star

This NASA/ESA Hubble Space Telescope image captures the remnants of a long-dead star. These rippling wisps of ionized gas, named DEM L316A, are located some 160,000 light-years away within one of the Milky Way's closest galactic ...

Extreme turbulence roiling 'most luminous galaxy' in the universe

The most luminous galaxy in the Universe - a so-called obscured quasar 12.4 billion light-years away - is so violently turbulent that it may eventually jettison its entire supply of star-forming gas, according to new observations ...

Rosetta's comet sings strange, seductive song

Scientists can't figure exactly why yet, but Comet 67P/Churyumov-Gerasimenko has been singing since at least August. Listen to the video – what do you think? I hear a patter that sounds like frogs, purring and ping-pong ...
