The protostar is located 1,300 light-years away in a busy nebula in the constellation of Orion.
Dark galaxies are small, gas-rich objects from the early universe.
This Hubble Space Telescope composite image shows a ghostly "ring" of dark matter in the galaxy cluster Cl 0024+17 in this stunning space wallpaper.
In this space wallpaper, using ESO's Very Large Telescope, an international team of astronomers has discovered a stunning rare case of a triple merger of galaxies.
Resembling a Fourth of July skyrocket, Herbig-Haro 110 is a geyser of hot gas from a newborn star that splashes up against and ricochets off the dense core of a cloud of molecular hydrogen in this cool space wallpaper.
This very detailed space wallpaper from ESO’s Very Large Telescope shows the dramatic effects of very young stars on the dust and gas from which they were born in the star-forming region NGC 6729.
The galaxy cluster is located 10 billion light-years away.
The survey will accurately catalog many faint stars for the first time.
The very first stars would have behaved differently because of dark matter.
The spectacular scene was captured by the European Southern Observatory's Very Large Telescope.
Our home in space is a vast galaxy containing 400 billion suns, at least that many planets, and a 4-billion-solar-mass black hole at the center.
Astronomers have found the farthest galaxy yet.
This cool space wallpaper shows an artist conception of a newly formed star surrounded by a swirling protoplanetary disk of dust and gas, where debris coalesces to create rocky 'planetesimals' that collide and grow to eventually form planets.

Researchers made a melody out of star brightness data collected by NASA's Kepler space telescope.
Though built from the same star stuff as our Sun, these celestial runts aren't bulky enough to catch fire from nuclear fusion. NASA's Wide-field Infrared Survey Explorer (WISE) has discovered fewer of these 'almost stars' than earlier predicted.
Observations by NASA's Wide-field Infrared Survey Explorer (WISE) have revealed a surprise — there are fewer brown dwarfs in our cosmic backyard than previously believed.
A bridge of hydrogen gas has been detected between two neighboring galaxies.
