A 'super-puff' planet like no other

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Universite de Montreal have found.
This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM's Institute for Research on Exoplanets (iREx) suggests that gas-giant planets form a lot more X-Rays surrounding 'Magnificent 7' may be traces of sought-after particle

A new study, led by a theoretical physicist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.
First theorized in the 1970s as part of a solution to a fundamental particle physics problem, axion China issues document to boost global cooperation on lunar samples

China published its Regulations on the Management of Lunar Samples on Monday morning, aiming to improve scientific research and international cooperation.
Developed by the China National Space Administration, the document has nine chapters and 37 clauses, governing the storage, management and use of lunar samples brought back by the country's Chang'e 5 mission.

English Astronaut vlog: space food and fitness
ESA astronaut Matthias Maurer is preparing for his mission to the International Space Station, scheduled for launch in late 2021. This mission is known as Cosmic Kiss.
In this video log from his current training base at NASA’s Johnson Space Center in Houston, Texas, USA, Matthias shows a space food tasting session and shares how astronauts maintain their fitness for a safe return to Earth.

The U.S. Postal Service to issue NASA sun science forever stamps
Write a comment
NASA's images of the sun's dynamic and dazzling beauty have captivated the attention of millions. In 2021, the US Postal Service is showcasing the sun's many faces with a series of sun Science forever stamps that show images of solar activity captured by NASA's Solar Dynamics Observatory, or SDO.
"I have been a stamp collector all my life and I can't wait to see NASA science highlighted in this way," said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate (SMD) in Washington. "I feel that the natural world around us is as beautiful as art, and it's inspiring to be able to share the import and excitement of studying the sun with people around the country.
Richard Branson's Virgin Orbit reaches space on 2nd try
Write a comment
Richard Branson's Virgin Orbit reached space on Sunday, eight months after the first demonstration flight of its air-launched rocket system failed, the company said.
A 70-foot-long (21.34-meter-long) LauncherOne rocket was released from beneath the wing of a Boeing 747 carrier aircraft off the coast of Southern California, ignited moments later and soared toward space.
The two-stage rocket carried a cluster of very small satellites known as CubeSats developed and built as part of a NASA educational program involving U.S.
Virgin Orbit rocket reaches orbit, satellites deployed

California-based Virgin Orbit made its first successful flight to orbit Sunday using a rocket launched from a plane over the Pacific Ocean, announcing later that the satellites aboard were released successfully.
The rocket soared into space at 2:40 p.m. EST after the company's Cosmic Girl aircraft, a modified Boeing 747-400, released it from beneath a wing.
"Payloads successfully NASA test of mega Moon rocket engines cut short
Write a comment
NASA conducted a test firing of the engines for its giant Space Launch System (SLS) lunar rocket on Saturday but they shut down earlier than planned, the space agency said.
The "hot-fire" test at the Stennis Space Center in Mississippi was supposed to last a little over eight minutes—the time the engines would burn in flight—but they shut down just over a minute into the burn.
"Teams are assessing the data to determine what caused the early shutdown, and will determine a path forward," NASA said in a statement.
The SLS rocket is intended to launch the Artemis missions that will take US astronauts back to the Moon.
Despite being cut short, NASA said the test of the RS-25 engines had provided valuable information for the planned missions.
