Green Bank Observatory 11 Jan 2021, 17:30 UTC In data gathered and analyzed over 13 years, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has found an intriguing low-frequency signal that may be attributable to gravitational waves.
Cherenkov Telescope Array 8 Jan 2021, 12:40 UTC Microquasars are Galactic binary systems composed of a star and a compact object (a black hole or a neutron star) that eats up matter from its companion, usually via an accretion disk, giving rise to relativistic jets, i.e. beams of particles moving almost at the speed of light. These jets, which can be either intermittent or persistent structures depending on the specific state of the system, emanate from the vicinity of the compact object and can expand light years away from the binary system.

ESA Top News 5 Jan 2021, 15:31 UTC NASA astronaut Mike Hopkins performs the Grasp experiment in the Columbus module of the International Space Station ahead of the New Year. The experiment studies how the central nervous system, specifically hand-eye coordination, adapts to microgravity.
NASA Breaking News 29 Dec 2020, 16:27 UTC Northrop Grumman’s uncrewed Cygnus spacecraft is scheduled to depart the International Space Station on Wednesday, Jan. 6, more than three months after delivering nearly 8,000 pounds of supplies, scientific investigations, commercial products, hardware, and other cargo to the orbiting outpost.
Kavli Institute for the Physics and Mathematics of the Universe 24 Dec 2020, 05:04 UTC The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.
MIT 22 Dec 2020, 19:15 UTC Today, the moon lacks a global magnetic field, but this wasn’t always the case. Spacecraft measurements of the moon’s crust and lunar rocks retrieved by the Apollo missions contain remnant magnetization that formed 4 to 3.5 billion years ago in a magnetic field comparable in strength to that of the Earth. Scientists have argued that the source of this was a dynamo — a magnetic field generated by the moon’s churning, molten, metal core. However, research indicates that the moon’s suspected small core may not have been able to generate enough energy to sustain the ancient magnetic field that planetary scientists have inferred from in its rocks.
ESA Top News 21 Dec 2020, 13:00 UTC The optical and infrared instruments of Euclid, ESA’s mission to study dark energy and dark matter, have passed the qualification and acceptance review and are now fully integrated into the spacecraft’s payload module. This marks an important step forward in the assembly of the Euclid space telescope, which is scheduled for launch in 2022.
NASA's Goddard Space Flight Center 18 Dec 2020, 15:00 UTC The narrow galaxy elegantly curving around its spherical companion in this image is a fantastic example of a truly strange and very rare phenomenon. This image, taken with the NASA/ESA Hubble Space Telescope, depicts GAL-CLUS-022058s, located in the southern hemisphere constellation of Fornax (the Furnace). GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our universe. The object has been nicknamed by astronomers studying this Einstein ring as the "Molten Ring," which alludes to its appearance and host constellation.
