Stars spin faster than expected as they age according to a new study led by scientists at the University of Birmingham which uses asteroseismology to shed new light on this emerging theory.
All stars, like the Sun, are born spinning. As they grow older, their spin slows down due to magnetic winds in a process called 'magnetic braking'. Research published in 2016 by scientists at Carnegie O Mars-directed coronal mass ejection erupts from the sun

NASA's STEREO-A and ESA/NASA's SOHO spacecraft detected a coronal mass ejection, or CME, leaving the sun on April 17 at 12:36 p.m. EDT. This CME did not impact Earth but did move toward Mars, passing the planet in the late evening and early morning hours of April 21 and 22.
The CME reached Mars two days after NASA's Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. NASA tracks such solar eruptions because solar eruptions can trigger particle and radiation events that pose a risk to astronauts and sensitive spacecraft electronics.
Asteroid that hit Botswana in 2018 likely came from Vesta
Friday, 23 April 2021 11:07 Write a comment
An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018. Guided by SETI Institute meteor astronomer Peter Jenniskens, they found 23 meteorites deep inside the Central Kalahari Game Reserve and now have published their findings online in the journal Meteoritics and Planetary Science.
"Combining the observations of the small asteroid in space with information gleaned from the meteorites shows it likely came from Vesta, second largest asteroid in our solar system and target of NASA's DAWN mission," said Jenniskens.

Liftoff of the Falcon 9 rocket and Crew Dragon spacecraft with ESA astronaut Thomas Pesquet, NASA astronauts Megan McArthur and Shane Kimbrough, and Japanese astronaut Aki Hoshide. The Crew-2 spend around 24 hours travelling to the International Space Station. The rocket lifted off at 11:49 on 23 April 2021 from Launchpad 39A in Cape Canaveral at NASA’s Kennedy Space Center in Florida, USA.
Thomas is the first ESA astronaut to fly in space in a vehicle other than the Russian Soyuz or the US Space Shuttle, and the first ESA astronaut to leave Earth from Florida, USA, in

“Climate change” is changing. There has been a growing push by scientists, environmental advocates and others to refer to the Earth’s changing climate as a “climate crisis” or even “climate emergency” to better reflect the severity of the problem and the urgency to take action to mitigate the worst of its effects.
