For the first time, astronomers have detected a signal from stars emerging in the early universe.

A research team has published a new study lead by Pat Roche, professor of astrophysics at The University of Oxford, and Chris Packham, associate professor of physics and astronomy at The University of Texas at San Antonio.

A Window Into The Cosmic Past

This image from the NASA/ESA Hubble Space Telescope shows the galaxy cluster PLCK G004.5-19.5.

Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago.

In an unprecedented deep survey for small, faint objects in the Orion Nebula, astronomers using NASA's Hubble Space Telescope have uncovered the largest known population of brown dwarfs sprinkled among newborn stars.

A new international study involving The Australian National University (ANU) has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that challenges a popular theory about how dwarf galaxies are spread around the Universe.

The study presents the discovery of one of the stars with the least content of "metals" (heavy elements) known.

Stars forming in galaxies appear to be influenced by the supermassive black hole at the center of the galaxy, but the mechanism of how that happens has not been clear to astronomers until now.

When scientists recorded a rippling in space-time, followed within two seconds by an associated burst of light observed by dozens of telescopes around the globe, they had witnessed, for the first time, the explosive collision and merger of two neutron stars.

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.
