Astronaut photography benefiting the planet
When astronauts take photographs of our planet while orbiting 400 km above our heads, they are doing much more than just taking pretty pictures. They are looking after the health of our planet and, ultimately, us too. Techniques used by astrophotographers looking at the stars and space exploration come together to measure the environmental impact of artificial lights at night.

Tidal Tails - The Beginning Of The End Of An Open Star Cluster
In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system.

"Better to dry a rocky planet before use"
Earth's solid surface and clement climate may be in part due to a massive star in the birth environment of the Sun. Without its radioactive elements injected into the early solar system, our home planet could be a hostile ocean world covered in global ice sheets. This is demonstrated by computer simulations in which the National Centre of Competence in Research PlanetS, based at the University of Bern, was involved.

Indonesia’s devastating 2018 earthquake was a rare ’supershear,’ according to UCLA-led study
The devastating 7.5 magnitude earthquake that struck the Indonesian island of Sulawesi last September was a rare “supershear” earthquake, according to a study led by UCLA researchers. Only a dozen supershear quakes have been identified in the past two decades, according to Lingsen Meng, UCLA's Leon and Joanne V.C. Knopoff Professor of Physics and Geophysics and one of the report's senior authors.

Gaia clocks new speeds for Milky Way-Andromeda collision
ESA's Gaia satellite has looked beyond our Galaxy and explored two nearby galaxies to reveal the stellar motions within them and how they will one day interact and collide with the Milky Way - with surprising results. Our Milky Way belongs to a large gathering of galaxies known as the Local Group and, along with the Andromeda and Triangulum galaxies - also referred to as M31 and M33, respectively - makes up the majority of the group's mass.

Giant impacts caused by interplanetary collisions
Astronomers have found fresh evidence for significant planetary diversity within a single exoplanet system, suggesting that giant high-speed collisions are partly responsible for planetary evolution. An international team of scientists led by Italy's National Institute for Astrophysics (INAF) and involving physicists from the University of Bristol spent three years observing the exoplanetary system Kepler-107 via the Telescopio Nazionale Galileo in La Palma.

Much of the surface ocean will shift in color by end of 21st century
Climate-driven changes in phytoplankton communities will intensify the blue and green regions of the world's oceans. Climate change is causing significant changes to phytoplankton in the world's oceans, and a new MIT study finds that over the coming decades these changes will affect the ocean's color, intensifying its blue regions and its green ones.

Active galaxies point to new physics of cosmic expansion
Investigating the history of our cosmos with a large sample of distant 'active' galaxies observed by ESA's XMM-Newton, a team of astronomers found there might be more to the early expansion of the Universe than predicted by the standard model of cosmology. According to the leading scenario, our Universe contains only a few percent of ordinary matter.

Black holes shed light on expanding Universe
Scientists are using supermassive black holes to measure the expansion of the early Universe. The researchers, including our astronomers here at Durham University, think that their measurements show the Universe might be growing more rapidly than previously thought. Supermassive black holes give off radiation as they feed and are some of the brightest points of light in space.

How to Escape a Black Hole: Simulations Provide New Clues to What’s Driving Powerful Plasma Jets
Black holes are known for their voracious appetites, binging on matter with such ferocity that not even light can escape once it's swallowed up. Less understood, though, is how black holes purge energy locked up in their rotation, jetting near-light-speed plasmas into space to opposite sides in one of the most powerful displays in the universe.

UofG astrophysicists welcome LIGO funding boost
University of Glasgow researchers are celebrating the announcement of tens of millions of dollars in new funding to advance the science of gravitational wave astrophysics. The US-based National Science Foundation announced today (Thursday 14 February) that Caltech and MIT will share in $20.4m (£15.9m) to upgrade the Laser Interferometer Gravitational-wave Observatory (LIGO), an NSF-funded international collaboration which made history in 2015 after making the first direct detection of gravitational waves.

Where is the Universe Hiding its Missing Mass?
Astronomers have spent decades looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. New results from NASA's Chandra X-ray Observatory may have helped them locate this elusive expanse of missing matter. From independent, well-established observations, scientists have confidently calculated how much normal matter - meaning hydrogen, helium and other elements - existed just after the Big Bang.

Colliding Exoplanets
There are currently about 2000 confirmed exoplanets with radii less than about three Earth-radii, and measurements of their densities reveal an astonishing diversity. Some have densities lower than Neptune which is made mostly of volatiles (materials less dense than metal and rock, but Neptune has almost four times the Earth's radius), while others appear to have rock-like densities, as high as the Earth's or higher.

Engineers program marine robots to take calculated risks
Algorithm could help autonomous underwater vehicles explore risky but scientifically-rewarding environments. We know far less about the Earth's oceans than we do about the surface of the moon or Mars. The sea floor is carved with expansive canyons, towering seamounts, deep trenches, and sheer cliffs, most of which are considered too dangerous or inaccessible for autonomous underwater vehicles (AUV) to navigate.
