Astronomers have used two Australian radio telescopes and several optical telescopes to study complex mechanisms that are fuelling jets of material blasting away from a black hole 55 million times more massive than the Sun.

Observations of two galaxies made with the National Science Foundation-funded Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope suggest that large galaxies formed faster than scientists had previously thought.

Cartography of the Cosmos

There are hundreds of billions of stars in our own Milky Way galaxy.

There are too many high-energy positrons in the cosmic rays reaching the Earth.

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.

A Chalmers-led team of astronomers has for the first time observed details on the surface of an aging star with the same mass as the Sun.

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.

The NASA/ESA Hubble Space Telescope has observed for the first time the source of a gravitational wave, created by the merger of two neutron stars.

Astronomers have shed fresh light on the importance of hydrogen atoms in the birth of new stars.

Astronomers have identified a white dwarf star in our galaxy that may be the leftover remains of a recently discovered type of supernova.

In 1887, American astronomer Lewis Swift discovered a glowing cloud, or nebula, that turned out to be a small galaxy about 2.2 million light years from Earth.

Hidden from our sight, the Westerhout 43 star-forming region is revealed in full glory in this far-infrared image from ESA's Herschel space observatory.

Australian scientists have discovered why heavyweight galaxies living in a dense crowd of galaxies tend to spin more slowly than their lighter neighbours.

Understanding the history of star formation in the Universe is a central theme in modern astronomy.

In June 2016, an international team of 31 astronomers, led by the University of Maryland's Eleanora Troja and including Arizona State University's Nathaniel Butler, caught a massive star as it died in a titanic explosion deep in space.

Chandra Samples Galactic Goulash

What would happen if you took two galaxies and mixed them together over millions of years? A new image including data from NASA's Chandra X-ray Observatory reveals the cosmic culinary outcome.

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have found new evidence suggesting that a jet of fast-moving material ejected from one young star may have triggered the formation of another, younger protostar.

For decades, scientists thought that the magnetic field lines coursing around newly forming stars were both powerful and unyielding, working like jail bars to corral star-forming material.

Stars form from gas and dust floating in interstellar space. But, astronomers do not yet fully understand how it is possible to form the massive stars seen in space.

The Balloon Experimental Twin Telescope for Infrared Interferometry (BETTII) payload, an astronomy experiment, launched from NASA's Columbia Scientific Balloon Facility (CSBF) in Palestine, Texas, Thursday, June 8, flying through the evening.
