Denver CO (SPX) Jun 18, 2021
The fifth Global Positioning System III (GPS III) satellite designed and built by Lockheed Martin is now headed to its orbit 12,550 miles above earth. This marks another step in supporting the U.S. Space Force's GPS satellite constellation modernization efforts.
Launched earlier this week, GPS III Space Vehicle 05 (GPS III SV05) is the latest next-generation GPS III satellite, a warfightin

San Francisco CA (SPX) Jun 16, 2021
Orbital Sidekick (OSK) announced the upcoming launch of its newest and most powerful hyperspectral imaging satellite: "Aurora." Aurora leverages OSK's previous experience collecting and analyzing hyperspectral data to provide action-oriented insights on the world around us, with a core focus on sustainability.
The Aurora satellite will serve OSK's customers in the energy, mining, and defen

Computer problem takes Hubble offline
Saturday, 19 June 2021 13:05
WASHINGTON — Spacecraft controllers are continuing to work on a faulty computer memory system on NASA’s Hubble Space Telescope that has stopped telescope operations for nearly a week.
A payload computer on Hubble stopped working June 13, the agency said in a June 16 statement.
Turkey invites Russia to take part in construction of country's spaceport

St. Petersburg (Sputnik) Jun 18, 2021
Earlier this year, media reported that Ankara was planning to build a spaceport in Somalia as part of a $1 billion investment in the nation's nascent space programme. Turkish authorities did not confirm this information, but President Recep Tayyip Erdogan did announce in February that Turkey would make a hard landing on the Moon by the year 2023.
Russia is invited to participate in the dev

Orchids in orbit: Seeds tested in space

Beijing (XNA) Jun 18, 2021
Almost 30 grams of Nanjing orchid seeds were carried into space for breeding tests, accompanying three Chinese astronauts in China's Shenzhou XII manned spaceship, which was launched on Thursday. The seeds will be in space for three months.
A red orchid variety, Hongcao, features red buds and seedlings, a popular variant from Nanjing county of Fujian province.
It was selected and bre

Study of young chaotic star system reveals planet formation secrets

Charlottesville VA (SPX) Jun 18, 2021
A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation. The results of the research

Researchers discover orbital patterns of trans-Neptunian objects

Abu Dhabi, UAE (SPX) Jun 18, 2021
Trans-Neptunian Objects (TNOs), small objects that orbit the sun beyond Neptune, are fossils from the early days of the solar system which can tell us a lot about its formation and evolution.
A new study led by Mohamad Ali-Dib, a research scientist at the NYU Abu Dhabi Center for Astro, Particle, and Planetary Physics, reports the significant discovery that two groups of TNOs with differen

How a supermassive black hole originates
Saturday, 19 June 2021 09:26
Riverside CA (SPX) Jun 18, 2021
Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion solar mass black holes are found when the universe was just 6% of i

When testing Einstein's theory of general relativity, small modeling errors add up fast
Saturday, 19 June 2021 09:26
Washington DC (SPX) Jun 18, 2021
Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein's theory of general relativity, suggest researchers at the University of Birmingham in the United Kingdom.
The findings, published June 16 in the journal iScience, suggest that catalogs with as few as 10 to 3

A wrinkle to the origins of matter in the Milky Way
Saturday, 19 June 2021 09:26
Baltimore MD (SPX) Jun 18, 2021
New findings published this week in Physical Review Letters suggest that carbon, oxygen, and hydrogen cosmic rays travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. Learning more about how cosmic rays move through the galaxy helps address a fundamental, lingering question in astrophysics: How is matter generated and distributed acr

Space scientists solve a decades-long gamma-ray burst puzzle

Bath UK (SPX) Jun 18, 2021
An international team of scientists, led by astrophysicists from the University of Bath in the UK, has measured the magnetic field in a far-off Gamma-Ray Burst, confirming for the first time a decades-long theoretical prediction - that the magnetic field in these blast waves becomes scrambled after the ejected material crashes into, and shocks, the surrounding medium.
Black holes are forme

Detector measures cosmic radiation on the Zugspitze

Bremen, Germany (SPX) Jun 18, 2021
Timepix3 was developed to detect elementary particles at the European Organization for Nuclear Research (CERN). It was then carried up to the International Space Station (ISS), where it measures the radiation dose to which astronauts and equipment are exposed. Most recently, Timepix3 has been used on the Zugspitze.
Its task is to simultaneously detect the secondary cosmic rays and radon de

Mystery of galaxy's missing dark matter deepens
Saturday, 19 June 2021 09:26
Baltimore MD (SPX) Jun 18, 2021
When astronomers using NASA's Hubble Space Telescope uncovered an oddball galaxy that looked like it didn't have much dark matter, some thought the finding was hard to believe and looked for a simpler explanation.
Dark matter, after all, is the invisible glue that makes up the bulk of the universe's matter. All galaxies appear to be dominated by it; in fact, galaxies are thought to form in

Mystery of Betelgeuse's dip in brightness solved
Saturday, 19 June 2021 09:26
Boston MA (SPX) Jun 18, 2021
When Betelgeuse, a bright orange star in the constellation of Orion, lost more than two-thirds of its brightness in late 2019 and early 2020, astronomers were puzzled.
What could cause such an abrupt dimming?
Now, in a new paper published Wednesday in Nature, an international team of astronomers reveal two never-before-seen images of the mysterious darkening --and an explanation. The
