Second strongest shock wave found in merging galaxy clusters

Astronomers have discovered the second-strongest merger shock in clusters of galaxies ever observed.

Discovered: ultra-elusive, super-energetic neutrinos from far-away galaxy

The capture of a burst of high-energy neutrinos from a far-off galaxy heralds a new era in astrophysics.

Size of monster black hole formed by trio of colliding galaxies stuns scientists

Three colliding spiral galaxies 1.8 billion light years from Earth have produced a monster black hole weighing in at 3 billion times the mass of the Sun

Dwarf Dark Galaxy Hidden in ALMA Gravitational Lens Image

Subtle distortions hidden in ALMA’s stunning image of the gravitational lens SDP.81 are telltale signs that a dwarf dark galaxy is lurking in the halo of a much larger galaxy nearly 4 billion light-years away. This discovery paves the way for ALMA to find many more such objects and could help astronomers address important questions on the nature of dark matter.In 2014, as part of ALMA’s Long Baseline Campaign, astronomers studied a variety of astronomical objects to test the telescope's new, high-resolution capabilities.

Monster black hole discovered in unlikely galaxy

Astronomers find a monster black hole 17 billion times more massive than the sun, raising suspicions supermassive black holes may be more common than first thought.

Astronomers report most 'outrageously' luminous galaxies ever observed

Astronomers report that they have observed the most luminous galaxies ever seen in the Universe, objects so bright that established descriptors such as 'ultra-' and 'hyper-luminous' used to describe previously brightest known galaxies don't even come close.

Quasars slowed star formation, new research shows: Study finding first observed evidence of galactic-wind phenomenon

Research has found new persuasive evidence that could help solve a longstanding mystery in astrophysics: why did the pace of star formation in the universe slow down some 11 billion years ago?

Mystery rays traced to giant black hole at galactic centre

Alien rays from outer space, which pass through our bodies every second of every day, have been traced to their source – a super-massive black hole that lies at the heart of our home galaxy, the Milky Way, German and Australian scientists have discovered.

ATLASGAL survey of Milky Way completed

A spectacular image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL).

Galaxy clusters are way more complicated than we thought

Galaxy clusters are groupings of hundreds to thousands of galaxies bound together by gravity, and are the most massive structures found in the universe.

Monstrous cloud boomerangs back to our galaxy

New Hubble telescope observations suggest that a high-velocity gas cloud was launched from the outer regions of our own galaxy around 70 million years ago. Now, the cloud is on a return collision course and is expected to plow into the Milky Way's disk in about 30 million years.

XXL Hunt for Galaxy Clusters

Observations from ESO telescopes provide crucial third dimension in probe of Universe's dark side. ESO telescopes have provided an international team of astronomers with the gift of the

Black holes have a size limit of 50 billion suns

Physicists have firmed up a theoretical limit on the mass of a black hole by figuring out when it will disrupt the disc that feeds it.

Astronomers capture most powerful explosion since big bang

Astronomers capture an image of the continuing eruption of the most powerful explosion since the big bang.
