Rosetta stone eruption on the sun could help explain solar explosions
Tuesday, 08 June 2021 11:45
In a dramatic, multi-staged eruption, the sun has revealed new clues that could help scientists solve the long-standing mystery of what causes the sun's powerful and unpredictable eruptions. Uncovering this fundamental physics could help scientists better predict the eruptions that cause dangerous space weather conditions at Earth.
This explosion contained components of three different types of solar eruptions that usually occur separately—making it the first time such an event has been reported. Having all three eruption types together in one event provides scientists with something of a solar Rosetta Stone, allowing them to translate what they know about each type of solar eruption to understand other types and uncover an underlying mechanism that could explain all types of solar eruptions.
"This event is a missing link, where we can see all of these aspects of different types of eruptions in one neat little package," said Emily Mason, lead author on the new study and solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It drives home the point that these eruptions are caused by the same mechanism, just at different scales.
Blue Canyon Technologies names new CEO

WASHINGTON — The U.S. government is poised to make large investments in environmental monitoring satellites but these efforts are not well coordinated across agencies that acquire these systems and the users of data collected by weather satellites, says a new report by the Aerospace Corp.
China releases new Mars image taken by Tianwen 1 probe
Tuesday, 08 June 2021 06:09
The China National Space Administration (CNSA) Monday released a new image taken by the Tianwen 1 probe, showing the country's first Mars rover and its landing platform on the red planet's surface.
In the image, taken by a high-resolution camera installed on the orbiter of Tianwen 1 at 6 pm on June 2 (Beijing Time), two bright spots are visible in the upper right corner. The larger one is Amazon's Jeff Bezos to go to space on Blue Origin rocket

Amazon founder Jeff Bezos announced plans on Monday to fly into space next month on a rocket built by his company Blue Origin, fulfilling what he said was a lifelong dream.
The 57-year-old billionaire said he and his brother Mark will blast off from Earth on July 20 on the first crewed flight of the company's New Shepard launch vehicle.

Going to the bathroom at the International Space Station is about to get easier and cleaner with a new toilet system that cost NASA $23 million to develop.
Astronauts are connecting and checking out the toilet, which actually is a high-tech improvement to the space station's water recycling system.

Tuesday, 08 June 2021 06:09
China tested a new rocket-booster parachute system during a recent launch from the southwest of the country, the China Aerospace Science and Technology Corporation said on Monday.
The system was tested on June 3 when the meteorological satellite Fengyun-4B was sent into a geostationary orbit via a Long March-3B carrier rocket from the Xichang Satellite Launch Center in Sichuan province. SpaceX's night-time launch sends SiriusXM satellite into orbit

Elon Musk's SpaceX launched a communications satellite for SiriusXM early Sunday from Florida in the first such mission since one of the broadcast company's spacecraft failed after launch in December.
The satellite, known as SXM-8, was lifted aboard a Falcon 9 rocket at 12:26 a.m. from Space Launch Complex 40 at Cape Canaveral Space Force Station. The launch, which occurred at the start of Axions could be the fossil of the universe researchers have been waiting for

Finding the hypothetical particle axion could mean finding out for the first time what happened in the Universe a second after the Big Bang, suggests a new study published in Physical Review D on June 7.

According to new research, Bdelloid rotifers, a class of microscopic invertebrates, can remain frozen for thousands of years and survive.

A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of galaxies 9 billion years ago, in the young universe.

Scientists from the University of Graz (Austria), Skoltech and their colleagues from the US and Germany have developed a new neural network that can reliably detect coronal holes from space-based observations. This application paves the way for more reliable space weather predictions and provides valuable information for the study of the solar activity cycle.

The aurora borealis, or northern lights, that fill the sky in high-latitude regions have fascinated people for thousands of years. But how they're created, while theorized, had not been conclusively proven.
In a new study, a team of physicists led by University of Iowa reports definitive evidence that the most brilliant auroras are produced by powerful electromagnetic waves during geomagne
