Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) surveyed dozens of young stars -- some Sun-like and others approximately double that size -- and discovered that the larger variety have surprisingly rich reservoirs of carbon monoxide gas in their debris disks.
Astronomers studying distant galaxies powered by monster black holes have uncovered an unexpected link between two very different wavelengths of the light they emit, the mid-infrared and gamma rays.
Astronomers have identified a young star, located almost 11,000 light years away, which could help us understand how the most massive stars in the Universe are formed.
In April 2016 the NASA/ESA Hubble Space Telescope celebrated its 26th year in orbit. More than a quarter of a century of intriguing observations and remarkable discoveries. But what is there left for Hubble, and the forthcoming James Webb Space Telescope, to do?
A new look at the debris from an exploded star in our galaxy has astronomers re-examining when the supernova actually happened.
University of Adelaide research has for the first time statistically proven that the earliest standing stone monuments of Britain, the great circles, were constructed specifically in line with the movements of the Sun and Moon, 5000 years ago.
This dramatic burst of colour shows a cosmic object with an equally dramatic history. Enveloped within striking, billowing clouds of gas and dust that form a nebula known as M1-67, sits a bright star named Hen 2-427 (otherwise known as WR 124).
Brown dwarfs are smaller than stars, but more massive than giant planets. As such, they provide a natural link between astronomy and planetary science.
NASA's Hubble Space Telescope has uncovered two tiny dwarf galaxies that have wandered from a vast cosmic wilderness into a nearby "big city" packed with galaxies.
Messier 18 was discovered and catalogued in 1764 by Charles Messier -- for whom the Messier Objects are named -- during his search for comet-like objects.
In an effort to fill in the blanks of the Standard Model of particle physics, science has been conducting a diligent search for a hypothesized particle known as the "sterile neutrino."
UCLA astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy.
Astronomers using the NASA/ESA Hubble Space Telescope, along with other telescopes on the ground and in space, have discovered a new type of exotic binary star
This NASA/ESA Hubble Space Telescope image captures the remnants of a long-dead star.
