Just after the Big Bang: Galaxies created stars a hundred times faster now
A team of astronomers has discovered a new kind of galaxy which, although extremely old -- formed less than a billion years after the Big Bang -- creates stars more than a hundred times faster than our own Milky Way.

Origin of Milky Way's hypothetical dark matter signal may not be so dark
A mysterious gamma-ray glow at the center of the Milky Way is most likely caused by pulsars. The findings cast doubt on previous interpretations of the signal as a potential sign of dark matter.

New survey hints at exotic origin for the Cold Spot
A supervoid is unlikely to explain a 'Cold Spot' in the cosmic microwave background, according to the results of a new survey, leaving room for exotic explanations like a collision between universes.

Light rays from a supernova bent by the curvature of space-time around a galaxy
Astronomers have detected for the first time multiple images from a gravitationally lensed Type Ia supernova. The new observations suggest promising new avenues for the study of the accelerated expansion of the universe, gravity and distribution of dark matter in the universe.

Hubble celebrates 27 years with two close friends
This stunning cosmic pairing of the two very different looking spiral galaxies NGC 4302 and NGC 4298 was imaged by the NASA/ESA Hubble Space Telescope. The image brilliantly captures their warm stellar glow and brown, mottled patterns of dust.

Collisions generate gas in debris disks
By examining the atomic carbon line from two young star systems -- 49 Ceti and Beta Pictoris -- researchers had found atomic carbon in the disk, the first time this observation has been made at sub-millimeter wavelength, hinting that the gas in debris disks is not primordial, but rather is generated from some process of collisions taking place in the debris disk.

Long ago and far away, an average galaxy: 'Typical' galaxy helps astronomers study epoch of reionization
Using a giant galaxy cluster as a cosmic-scale lens, astronomers have discovered a galaxy from the early universe that they think is 'typical' of its time. This could help astronomers better understand the Epoch of Reionization when the first galaxies appeared.

Doubly accelerated electrons detected in collisions of galaxy clusters
A cosmic phenomenon resulting from the acceleration of a gas cloud by a black hole and its reacceleration by the shock waves from the merging of two galaxy clusters has been described by an international collaboration of astronomers. The study enriches scientists' understanding of the universe on the largest scale.
