Astronomers spot ‘vampire’ star sucking life from victim

Astronomers have found a ‘vampire’ star in the midst of a feeding frenzy, with the help of an automated program that is sifting through archived data from the decommissioned Kepler Space Telescope. The research is published in the Monthly Notices of the Royal Astronomical Society. The new program acts like a detective to find clues of … Read more Astronomers spot ‘vampire’ star sucking life from victim

ESO telescope images stunning central region of Milky Way, finds ancient star burst

ESO’s Very Large Telescope (VLT) has observed the central part of the Milky Way with spectacular resolution and uncovered new details about the history of star birth in our galaxy. Thanks to the new observations, astronomers have found evidence for a dramatic event in the life of the Milky Way: a burst of star formation … Read more ESO telescope images stunning central region of Milky Way, finds ancient star burst

Hidden giant planet revealed around tiny white dwarf star

The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its evaporating atmosphere. The Neptune-like planet orbits a star a quarter of its size about once every ten days, leaving a comet-like tail of gas comprised of hydrogen, oxygen … Read more Hidden giant planet revealed around tiny white dwarf star

Milky Way’s big black hole hurls star to infinity and beyond

An international study has discovered a star travelling at more than six million km/h through the Milky Way after being flung from the centre of our galaxy by a supermassive black hole. The eviction occurred about five million years ago, around the time when our ancestors were just learning to walk upright. Emeritus Professor Gary … Read more Milky Way’s big black hole hurls star to infinity and beyond

Carbon grains around evolved stars

Stardust, an ultra-high vacuum machine built in the project Nanocosmos ERC, was specifically conceived to simulate, with a high level of control, the complex conditions of stardust formation and processing in the environment of evolved stars. In addition, the AROMA setup was built to analyse the molecular content of the samples synthesized by Stardust. In … Read more Carbon grains around evolved stars

Gas ‘waterfalls’ reveal infant planets around young star

The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of disks made with the Atacama Large Millimeter/submillimeter Array (ALMA) how distinct gaps and ring features in dust, which may be caused by infant planets. To get more … Read more Gas ‘waterfalls’ reveal infant planets around young star

Scientists watch a black hole shredding a star

A NASA satellite searching space for new planets gave astronomers an unexpected glimpse at a black hole ripping a star to shreds. It is one of the most detailed looks yet at the phenomenon, called a tidal disruption event (or TDE), and the first for NASA’s Transiting Exoplanet Survey Satellite (more commonly called TESS.) The … Read more Scientists watch a black hole shredding a star

Busy older stars outpace stellar youngsters, new study shows

The oldest stars in our Galaxy are also the busiest, moving more rapidly than their younger counterparts in and out of the disk of the Milky Way, according to new analysis carried out at the University of Birmingham. The findings provide fresh insights into the history of our Galaxy and increase our understanding of how … Read more Busy older stars outpace stellar youngsters, new study shows

Maximum mass of lightest neutrino revealed using astronomical big data

Neutrinos come in three flavours made up of a mix of three neutrino masses. While the differences between the masses are known, little information was available about the mass of the lightest species until now. It’s important to better understand neutrinos and the processes through which they obtain their mass as they could reveal secrets … Read more Maximum mass of lightest neutrino revealed using astronomical big data

A second planet in the Beta Pictoris system

A team of astronomers led by Anne-Marie Lagrange, a CNRS researcher at the Institut de Planétologie et d’Astrophysique de Grenoble (CNRS/Université Grenoble Alpes)1, has discovered a second giant planet in orbit around β Pictoris, a star that is relatively young (23 million years old) and close (63.4 light years), and surrounded by a disk of … Read more A second planet in the Beta Pictoris system
