Giant meteorite crater found beneath Greenland’s ice sheet
A giant crater left over from the catastrophic impact of a meteorite crashing into Earth has been uncovered deep below the ice sheets in Greenland. The 31 km-wide crater, which is bigger than Paris, has been discovered by an international team of scientists who believe it to have been caused by a meteorite impact on Earth between 3 million and 12,000 years ago.

Newly discovered planet sets Barnard’s Star in motion
International team unveils Super Earth at second closest star to the Earth. Scientists have discovered a planet in the orbit of Barnard's Star, which is about six light years from us. They assume that the planet, which has about 3.2 times as much mass as Earth, orbits the star. This was discovered by an international team involving the University of Göttingen.

Once-In-A-Lifetime Observations by Veritas Astronomers Reveal High Energy Gamma-Rays from a Binary Star System
Once-In-A-Lifetime Observations by Veritas Astronomers Reveal High Energy Gamma-Rays from a Binary Star System
A new discovery reported in the Astrophysical Journal Letters might lay claim to title of the most unusual extreme class of astronomical object: very high energy (VHE) gamma-ray emitting, neutron star-massive star binary pairs. Of the one-hundred billion stars in our galaxy, fewer than ten are in known to be in gamma-ray binary systems, with this discovery being only the second with an identified neutron star.

Gaia spots a 'ghost' galaxy next door
Gaia spots a ’ghost’ galaxy next door
The Gaia satellite has spotted an enormous 'ghost' galaxy lurking on the outskirts of the Milky Way. When we looked closer, it turned out we found something new Vasily Belokurov An international team of astronomers, including from the University of Cambridge, discovered the massive object when trawling through data from the European Space Agency's Gaia satellite.

Enormous 'ghost' galaxy spotted hiding next to the Milky Way
Enormous ’ghost’ galaxy spotted hiding next to the Milky Way
A galaxy a third the size of our own, but extremely faint, has been observed orbiting around the Milky Way. An international team, including an astronomer from Imperial College London, discovered the massive galaxy when trawling through data from the European Space Agency's Gaia satellite. Despite its size, the galaxy has very few stars, challenging conventional theories of galaxy formation.

Astronomers witness David-vs-Goliath fight between galaxies
Astronomers witness David-vs-Goliath fight between galaxies
Astronomers have witnessed, in the finest detail yet, a brutal David-vs-Goliath fight between two nearby galaxies that are tearing chunks from each other and flinging them into the gaseous Magellanic Stream, a cosmic river of blood encircling our Milky Way. The new study led by ANU investigated the violent stoush between the Large and Small Magellanic Clouds - dwarf galaxies on the Milky Way's periphery that are visible at night with the naked eye from the southern hemisphere.

ESA's gravity-mapper reveals relics of ancient continents under Antarctic ice
ESA’s gravity-mapper reveals relics of ancient continents under Antarctic ice
ESA Observing the Earth GOCE It was five years ago this month that ESA's GOCE gravity-mapping satellite finally gave way to gravity, but its results are still yielding buried treasure - giving a new view of the remnants of lost continents hidden deep under the ice sheet of Antarctica. A research team from Germany's Kiel University and the British Antarctic Survey published their latest GOCE-based findings this week in the journal Scientific Reports .

Cosmic fountain offers clues to how galaxies evolve
Cosmic fountain offers clues to how galaxies evolve
Galaxy evolution can be chaotic and messy, but it seems that streams of cold gas spraying out from the region around supermassive black holes may act to calm the storm. This is according to an international team of scientists who have provided the first clear and compelling evidence of this process in action.

E.T., we're home
E.T., we’re home
Existing laser technology could be fashioned into Earth's "porch light" to attract alien astronomers, study finds. If extraterrestrial intelligence exists somewhere in our galaxy, a new MIT study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light - a beacon strong enough to attract attention from as far as 20,000 light years away.

Comet tails: charged dust blowing in the solar wind
Comet tails: charged dust blowing in the solar wind
How a comet's dust tail forms bands stretching millions of kilometres across the sky has been observed for the first time by UCL scientists. The study, published today in Icarus, reveals the charged nature of the dust particles and the important role of the Sun in forming the characteristic patterns.

Galactic ghosts: Gaia uncovers major event in the formation of the Milky Way
Galactic ghosts: Gaia uncovers major event in the formation of the Milky Way
ESA ESA Science Gaia 31 October 2018 ESA's Gaia mission has made a major breakthrough in unravelling the formation history of the Milky Way. Instead of forming alone, our Galaxy merged with another large galaxy early in its life, around 10 billion years ago. The evidence is littered across the sky all around us, but it has taken Gaia and its extraordinary precision to show us what has been hiding in plain sight all along.

Scientist wins prestigious award for gravitational wave detection
A scientist involved in creating the ultra-sensitive detectors needed to glimpse gravitational waves for the very first time has been awarded a prestigious Philip Leverhulme Prize. Dr Katherine Dooley, from Cardiff University's School of Physics and Astronomy, has picked up the £100,000 prize for scientific work 'that has had a significant international impact'.

Missing gamma-ray blobs shed new light on dark matter, cosmic magnetism
Astrophysicists use a catalog of extended gamma-ray sources spotted by Fermi spacecraft to home in on mysterious properties of deep space. When astrophysicists look at the gamma-ray glow from a galaxy outside our own, all they typically see is a small spot because the galaxy is extremely far away. So, when a galaxy appears as an extended blob, something extraordinary must be going on that could help researchers better understand the properties of deep space.

Astronomers witness slow death of nearby galaxy
Astronomers from ANU and CSIRO have witnessed, in the finest detail ever, the slow death of a neighbouring dwarf galaxy, which is gradually losing its power to form stars. The new peer-reviewed study of the Small Magellanic Cloud (SMC), which is a tiny fraction of the size and mass of the Milky Way galaxy, uses images taken with CSIRO's powerful Australian SKA Pathfinder (ASKAP) radio telescope.

Model Describing Conditions Under Which Oxygenated Water Could Exist on Mars Challenges Traditional Beliefs About Planet’s Habitability
Given the right circumstances, water on Mars could hold more oxygen than previously believed, theoretically enough to support aerobic respiration A team led by scientists at Caltech and the Jet Propulsion Laboratory (JPL), which Caltech manages for NASA, has calculated that if liquid water exists on Mars, it could-under specific conditions-contain more oxygen than previously thought possible.

Gravitational waves could soon provide measure of universe’s expansion
Twenty years ago, scientists were shocked to realize that our universe is not only expanding, but that it's expanding faster over time. Pinning down the exact rate of expansion, called the Hubble constant after famed astronomer and UChicago alumnus Edwin Hubble, has been surprisingly difficult. Since then scientists have used two methods to calculate the value, and they spit out distressingly different results.

Journey to Mercury with Involvement from Bern
Journey to Mercury with Involvement from Bern
On Saturday 20 October 2018, at 03:45 a.m. CET, the BepiColombo space probe is to set off on its journey to Mercury from the European spaceport in Kourou, French Guiana. On board the European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA)'s joint space probe are instruments which were designed and built at the Physics Institute of the University of Bern: the laser altimeter BELA-the largest and most sensitive instrument of the mission-and the innovative mass spectrometer STROFIO.
