The two newly-discovered pairs of quasars, J0749+2255 and J0841+4825, existed 10 billion years ago and resided in the cores of merging galaxies, according...
The source of the 160,000-light-year-long jet of particles is PSO J352.4034-15.3373 (PJ352-15 for short), a rapidly growing supermassive black hole, or...
Astronomers using several ground-based telescopes have spotted the most distant cosmic jet discovered so far. Its source is PSO J172.3556+18.7734, a radio-loud...
Recent measurements of the expansion rate of the Universe have plunged the standard model of cosmology, the ΛCDM model, into a crisis. In a new paper...
ALESS 073.1, a star-forming galaxy located 12.5 billion light-years away, has all of the features expected of a much more mature galaxy and has led astronomers...
The newly-discovered quasar is located approximately 13.03 billion light-years away from Earth. Designated J031343.84-180636.4 (J0313-1806 for short),...
In a new paper in the journal Physical Review Letters, an international team of theoretical physicists described a scenario for the formation of primordial...
GN-z11, a young but moderately massive galaxy located in the constellation of Ursa Major, is estimated to date from when the Universe was only 420 million...
Using the polarization data from ESA’s Planck satellite, a mission that have studied the Cosmic Microwave Background (CMB), the oldest light in the Universe,...
The mean temperature of gas across the Universe has increased more than 10 times over the last 10 billion years and reached about 2 million Kelvin today,...
SDSS J0901+1814, a giant galaxy cluster located 3.9 billion light-years away in the constellation of Cancer, is so massive that its gravity distorts and...
In a paper published this month in the journal Physical Review Letters, an international team of physicists described a new mechanism of dark matter production.

Astronomers using the High-Resolution Echelle Spectrometer (HIRES) on the Keck I telescope at W. M. Keck Observatory and the Canada-France-Hawaii Telescope...
Using the MUSE and FORS2 instruments on ESO’s Very Large Telescope (VLT), astronomers have spotted a group of six galaxies around SDSS J1030+0524, a...
A young starburst galaxy named BOSS-EUVLG1 is by far the most luminous, almost un-obscured star-forming galaxy known at any redshift.
An artist’s impression...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered an extremely distant galaxy that looks surprisingly like our...
The Phoenix stellar stream, a thin over-density of stars in the halo of our Milky Way Galaxy originally identified by the Dark Energy Survey, is composed...
Astrophysicists and cosmologists from the Sloan Digital Sky Survey (SDSS) have released the largest 3D map of the Universe ever created, filling in the...
An international of astronomers has observed an optical afterglow of a short gamma-ray burst, thought to be from the merger of two neutron stars, and localized...
