A Bridge of Dark Matter Detected

  Direct measurement of a dark-matter ‘filament’ confirms its existence in a galaxy supercluster.   A ‘finger’ of the Universe’s dark-matter skeleton, which ultimately dictates where galaxies form, has been observed for the first time. Researchers have directly detected a slim bridge of dark matter joining two clusters of galaxies, using a technique that could [continue reading]

'Impossible' Binary Stars Discovered

  A team of astronomers have used the United Kingdom Infrared Telescope (UKIRT) on Hawaii to discover four pairs of stars that orbit each other in less than 4 hours. Until now it was thought that such close-in binary stars could not exist. The new discoveries come from the telescope’s Wide Field Camera (WFCAM) Transit [continue reading]

Newly Found Primitive Mineral in the Allende Meteorite

  In 1969, an exploding fireball tore through the sky over Mexico, scattering thousands of pieces of meteorite across the state of Chihuahua. More than 40 years later, the Allende meteorite is still serving the scientific community as a rich source of information about the early stages of our Solar System’s evolution. Recently, scientists from [continue reading]

Extensive Water in Mars Interior

  Until now, Earth was the only planet known to have vast reservoirs of water in its interior. Scientists analyzed the water content of two Martian meteorites originating from inside the Red Planet. They found that the amount of water in places of the Martian mantle is vastly larger than previous estimates and is similar [continue reading]

How the Universe Escaped its 'Dark Ages'

  An international team of astronomers have uncovered an important clue about how the Universe emerged from its ‘dark ages’ some 13 billion years ago. By looking at nearby galaxies, they can infer what may have happened to the first galaxies of our Universe. The large elliptical galaxy NGC1407 is located at the centre of [continue reading]

Globular Star Clusters: The Survivors of a Massacre

  Our Milky Way galaxy is surrounded by some 200 compact groups of stars, containing up to a million stars each. At 13 billion years of age, these globular clusters are almost as old as the universe itself and were born when the first generations of stars and galaxies formed. A team of astronomers from [continue reading]
