An international team of astronomers has detected the most distant radio galaxy ever observed. By measuring the redshift of its light, the researchers determined that the object is about 12 billion light-years away, which dates it back to when the universe itself was just a kid.

Discoveries that back up Einstein’s theory of general relativity are still being made. The latest comes from the Max Planck Institute, where astronomers have watched how the supermassive black hole at the center of the Milky Way pulls and stretches the light from a star as it makes its closest pass.

According to a newly-released paper, the Andromeda galaxy may have committed fratricide on a cosmic scale some 2 billion years ago, by ripping apart an enormous galaxy, and cannibalizing much of the body.

The MeerKAT radio telescope array is finally up and running in South Africa. To show off what the facility can do, astronomers have pointed all 64 antennas towards the center of the Milky Way galaxy, and snapped one of the clearest shots ever taken of the mysterious region.

About 3.7 billion years ago, a neutrino was thrown out of a blazar and launched towards Earth. The ghostly particle was detected by the IceCube Neutrino Observatory in Antarctica and traced back to its point of origin, helping to confirm the most distant neutrino source ever identified.

An international team of astronomers has now found evidence of a celestial smash-up between the Milky Way and an unknown dwarf galaxy that took place around eight to 10 billion years ago, and forever changed the face of our home galaxy.

Astronomers have detected some strange objects at the center of the Milky Way. They look like ordinary clouds of gas, but seem to have a solid core that keeps them together. The truth may lie somewhere in-between. These G-objects, as they’re known, seem to be stars hiding under puffy shrouds of dust

An international team of astronomers has completed the most comprehensive ultraviolet survey of the local universe to date, with the help of the Hubble Space Telescope. The survey could help scientists better understand how stars come to form, and how galaxies like our own evolve over time.

Elements like oxygen, carbon and nitrogen weren’t very common until the first stars had fired up, burnt out and exploded. Now, astronomers using ALMA have detected the most distant – and hence, earliest – signature of oxygen, in a galaxy 13.28 billion light-years away.

ESA has taken a “galactic census” of the Milky Way, unveiling the second major data release from the Gaia mission. The data release provides the most detailed map of our home galaxy, which includes data of nearly 1.7 billion stars, plus the orbits and positions of thousands of asteroids.
