The results of a comprehensive search for a background of ultra-low frequency gravitational waves has been announced by an international team of astronomers including scientists from the Institute for Gravitational Wave Astronomy at the University of Birmingham. These light-year-scale ripples, a consequence of Einstein's theory of general relativity, permeate all of spacetime and could ori

Planet Labs PBC reports announced that the launch of their Flock 4x, consisting of 44 SuperDove satellites, will take place on Thursday, January 13th on SpaceX's Falcon 9 Transporter-3 SSO. This marks the first satellite launch under Planet's new multi-year, multi-launch rideshare agreement with SpaceX. Planet operates the world's largest constellation of Earth observation satellites; and

On Thursday 13 January the Cape Peninsula University of Technology is set to launch its third satellite mission into space from the Cape Canaveral launch site in the USA. The MDASat (Marine Domain Awareness) constellation has two main priorities namely ocean economy and healthcare and has been mandated by the Department of Science and Innovation to enhance South Africa's ocean's sovereignt

A solar eclipse over the Arctic created changes in auroras in both of Earth's hemispheres due to connections through the planet's magnetic field, according to a new study. The new work could help scientists predict changes in the near-Earth environment that can interfere with satellite communication. On 10 June 2021, the moon's shadow darkened much of the Earth's northern polar region, pro

EK Draconis illuminates an unimagined picture of how superflares may affect interplanetary space through coronal mass ejections Welcome to the New Year! While Earth celebrated 2022's arrival with displays of fireworks, the greatest "fireworks show" in our solar system often occurs on the Sun. Its atmosphere is a venue for dynamic sunspots, solar flares, and dramatic encores of released magnetic

The Earth sits in a 1,000-light-year-wide void surrounded by thousands of young stars - but how did those stars form? In a paper appearing in Nature, astronomers at the Center for Astrophysics | Harvard and Smithsonian (CfA) and the Space Telescope Science Institute (STScI) reconstruct the evolutionary history of our galactic neighborhood, showing how a chain of events beginning 14 million

Webb has begun the detailed process of fine-tuning its individual optics into one huge, precise telescope. Engineers first commanded actuators - 126 devices that will move and shape the primary mirror segments, and six devices that will position the secondary mirror - to verify that all are working as expected after launch. The team also commanded actuators that guide Webb's fine steering

Green Bank WV (SPX) Jan 13, 2022
An international team of astronomers has discovered what could be the early sign of a background signal arising from supermassive black holes, observed through low-frequency gravitational waves. These scientists are comparing data collected from several instruments, including the National Science Foundation's Green Bank Telescope (GBT.) Gravitational Waves ripple through spacetime at a lig

Scientists have witnessed for the first time exactly what happens to the most massive stars at the end of their lives. Most very large stars explode in a fiery supernova explosion that leaves behind a neutron star in a process frequently witnessed by Earth's most powerful telescopes. But some - the most massive, 30 times the size of the Sun or more - are believed to undergo a less vi
