By combining the power of strong gravitational lensing with the capability of the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers from Japan... more
ESA to conduct BepiColombo flyby amid coronavirus crisis  PHYS.ORG · 3 days
Controllers at ESA's mission control center are preparing for a gravity-assist flyby of the European-Japanese Mercury explorer BepiColombo. The maneuver, which will see the mission adjust its trajectory by harnessing Earth's gravitational... more
Water pressure: Ancient aquatic crocs evolved, enlarged to avoid freezing  PHYS.ORG · 3 days
Taking the evolutionary plunge into water and abandoning land for good, as some crocodilian ancestors did nearly 200 million years ago, is often framed as choosing freedom: from... more

Controllers at ESA’s mission control centre are preparing for a gravity-assist flyby of the European-Japanese Mercury explorer BepiColombo. The manoeuvre,... more
Free-floating stars in the Milky Way's bulge  PHYS.ORG · 4 days
The path of a light beam is bent by the presence of mass, as explained by General Relativity. A massive body can therefore act like a lens—a so called "gravitational lens"—to distort the image... more
Dark matter and massive galaxies  PHYS.ORG · 2 weeks
About 85% of the matter in the universe is in the form of dark matter, whose nature remains a mystery, and the rest is of the kind found in atoms. Dark matter exhibits gravity but otherwise does not... more

A team of researchers have published new calculations that predict a striking and intricate substructure within black hole images from extreme gravitational light bending. more
Research team discovers path to razor-sharp black hole images  PHYS.ORG · 2 weeks
Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole. Today, a team of researchers have published new calculations that... more
Precision mirrors poised to improve sensitivity of gravitational wave detectors  PHYS.ORG · 2 weeks
Researchers have developed a new type of deformable mirror that could increase the sensitivity of ground-based gravitational wave detectors such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO).... more
Waves in thin air with broad effects  PHYS.ORG · 2 weeks
Mars has a very thin atmosphere, with nearly one hundredth the density of ours on Earth, and gravity pulls with little more than one third of the strength we feel on our planet. As... more
