As NASA's Perseverance rover begins its search for ancient life on the surface of Mars, a new study suggests that the Martian subsurface might be a good place to look for possible present-day life on the Red Planet. The study, published in the journal Astrobiology, looked at the chemical composition of Martian meteorites - rocks blasted off of the surface of Mars that eventually landed on

Rain is a common phenomenon on Earth. There is a similar phenomenon on the Sun, called coronal rain. It is related to the coronal heating and magnetic field, and plays a fundamental role in the mass cycle between the hot, tenuous corona and the cool, dense chromosphere. Coronal rain usually takes place in post-flare loops and the non-flaring active region coronal loops. It is generally cla

In the continuing search for dark matter in our universe, scientists believe they have found a unique and powerful detector: exoplanets. In a new paper, two astrophysicists suggest dark matter could be detected by measuring the effect it has on the temperature of exoplanets, which are planets outside our solar system. This could provide new insights into dark matter, the mysterious s

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 CME 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 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

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

The Crew-2 mission blasts off from pad 39A at the Kennedy Space Center in Florida at 5:49 am Eastern Time (0949 GMT) on April 23, 2021, after being delayed a day by adverse weather along the flight path 

SpaceX is set to launch its third crew to the International Space Station an hour before sunrise Friday, recycling a rocket and spacecraft for the first time.

The Crew-2 blasts off from pad 39A at the Kennedy Space Center in Florida at 5:49 am Eastern Time (0949 GMT), after being delayed a day by adverse weather along the flight path.

Around 2:30 am (0630 GMT), Thomas Pesquet of France—the first European on a SpaceX mission—along with Americans Shane Kimbrough and Megan McArthur and Japan's Akihiko Hoshide strode out in their suits to say goodbye to their families.
