Air passengers will soon be able to cut their carbon footprint when travelling on flights that are routed using satellites.
Like a witness to a violent death, NASA's Hubble Space Telescope recently gave astronomers an unprecedented, comprehensive view of the first moments of a star's cataclysmic demise. Hubble's data, combined with other observations of the doomed star from space- and ground-based telescopes, may give astronomers an early warning system for other stars on the verge of blowing up. "We used to ta
New images have revealed detailed clues about how the first stars and structures were formed in the Universe and suggest the formation of the Galaxy got off to a fitful start. An international team of astronomers from the University of Nottingham and Centro de Astrobiologia (CAB, CSIC-INTA) used data from the Hubble Space Telescope (HST) and the Gran Telescopio Canarias (GTC), the so-called Fron
Collectively clocking in at nearly 60 trillion particles, a newly released set of cosmological simulations is by far the biggest ever produced. The simulation suite, dubbed AbacusSummit, will be instrumental in extracting secrets of the universe from upcoming surveys of the cosmos, its creators predict. They present AbacusSummit in several papers published October 25 in Monthly Notices of the Ro
A dam deformation monitoring system based on BeiDou Navigation Satellite System has been put into operation in Usoi Dam in Tajikistan, according to China's National Time Service Center (NTSC) under the Chinese Academy of Sciences (CAS). Sarez Lake, located in the Pamir region in eastern Tajikistan, has an altitude of 3,263 meters above sea level. It was naturally created in 1911 when an ea
Astronomers searching for Earth-like planets in other solar systems have made a breakthrough by taking a closer look at the surface of stars.
A new technique developed by an international team of researchers—led by Yale astronomers Rachael Roettenbacher, Sam Cabot, and Debra Fischer—uses a combination of data from ground-based and orbiting telescopes to distinguish between light signals coming from stars and signals coming from planets orbiting those stars.
A study detailing the discovery has been accepted by The Astronomical Journal.
"Our techniques pull together three different types of contemporaneous observations to focus on understanding the star and what its surface looks like," said Roettenbacher, a 51 Pegasi b postdoctoral fellow at Yale and lead author of the paper.
After a successful test run in May, a NASA campaign is deploying aircraft, a research vessel and several kinds of autonomous ocean robots to study small ocean whirlpools, eddies and currents. Using instruments at sea and in the sky, the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) team aims to understand the role these ocean processes play in vertical transport, the movement of heat, nutrien
Verizon announced on Tuesday that it will use a satellite communications system that's being put together by Amazon to expand broadband Internet access to rural areas of the United States. In announcing the partnership, the companies said the plan is intended to bring access to unserved and underserved U.S. communities. Amazon is planning to send more than 3,200 satellites into orbit
Much of the space junk orbiting Earth won't clean up itself - or tell you how it got there. Purdue University's Carolin Frueh and her team are investigating what causes spacecraft to become space junk. Their findings are revealing ways to prevent spacecraft from breaking apart into thousands of pieces of debris that pose a threat to space stations and satellites. Since 1957, there have bee
From developing our space tracking capabilities and promoting international efforts in space sustainability, to finding novel ways of removing space debris - the UK is leading the way to ensure the Earth's orbit can continue to be used now and in the future. Orbital congestion and space debris remains one of the biggest global challenges facing the space sector. There are currently an esti
