Scientists searching for gravitational waves have confirmed yet another detection from their fruitful observing run earlier this year.

Zwicky Transient Facility Sees First Light

Zwicky Transient Facility Sees First Light

A new robotic camera with the ability to capture hundreds of thousands of stars and galaxies in a single shot has taken its first image of the sky -- an event astronomers refer to as "first light."


Contracting White Dwarf Observed For The First Time

Contracting White Dwarf Observed For The First Time

Astrophysicists from MSU (Russia) and his colleagues from Italy and Russian Academy of Sciences have found the first observational evidence for a contracting white dwarf.


Two Galaxies In An Extreme Starbursting Merger

Two Galaxies In An Extreme Starbursting Merger

New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) have uncovered the never-before-seen close encounter between two astoundingly bright and spectacularly massive galaxies in the early universe.


Listening for Gravitational Waves Using Pulsars

Listening for Gravitational Waves Using Pulsars

One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space.


Hubble Spots Expanding Light Echo Around Supernova

Light from a supernova explosion in the nearby starburst galaxy M82 is reverberating off a huge dust cloud in interstellar space.


A Star That Would Not Die

A Star That Would Not Die

Supernovae, the explosions of stars, have been observed by the thousands. And in all cases, the transient astronomical events signaled the death of those stars.

The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri.


New Insight into Nature's Own Death Star Beams

New Insight into Nature's Own Death Star Beams

Scientists from the University of Sheffield have moved a step closer to understanding nature's own Star Wars Death Star beams -- ultra powerful jets of energy that shoot out from the vicinity of black holes.


Hubble Discovers Wobbling Galaxies

Hubble Discovers Wobbling Galaxies

Using the NASA/ESA Hubble Space Telescope, astronomers have discovered that the brightest galaxies within galaxy clusters "wobble" relative to the cluster's centre of mass.


Revealing Galactic Secrets

Revealing Galactic Secrets

Captured using the exceptional sky-surveying abilities of the VLT Survey Telescope (VST) at ESO's Paranal Observatory in Chile, this deep view reveals the secrets of the luminous members of the Fornax Cluster, one of the richest and closest galaxy clusters to the Milky Way.


Supergiant Star Spots Drive Stellar Wind Spirals

Supergiant Star Spots Drive Stellar Wind Spirals

A Canadian-led international team of astronomers recently discovered that spots on the surface of a supergiant star are driving huge spiral structures in its stellar wind.
