In results announced this week at the 237th Meeting of the American Astronomical Society, scientists from the Sloan Digital Sky survey present the most detailed look yet at the warp of our own Galaxy.
"Our usual picture of a spiral galaxy is as a flat disk, thinner than a pancake, peacefully rotating around its center," said Xinlun Cheng of the University of Virginia, the lead author of th Statement on Satellite Constellations by German Astronomical Society

The German Astronomical Society (AG), the German association of amateur astronomers (VdS) and the Society of German-Speaking Planetariums (GDP) comment on the rapid increase in the number of satellites in the night sky. Artificial satellites have significant impact on the perception of the natural starry sky and the exploration of our universe.

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
Sunday, 17 January 2021 12:22 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.
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.

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.

NASA test of mega Moon rocket engines cut short
Saturday, 16 January 2021 18:40 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.

NASA's plan to test its new moon rocket fell short of a scheduled eight-minute test-firing Saturday in Mississippi as the engines were shut down at just over a minute into the test.
The 212-foot-high core stage of the rocket roared to life at 5:27 p.m. at the John C. Stennis Space Center. The test created huge clouds of steam as 300 gallons of water per minute cooled the test stand to prev Virgin Orbit targets Sunday for LauncherOne mission from California

Virgin Orbit plans to try again Sunday to send 10 small science satellites for NASA and several universities into orbit using a rocket launched over the Pacific Ocean.
The mission is scheduled to begin at 10 a.m. PST when Virgin's Cosmic Girl aircraft, a modified Boeing 747, takes off from Mojave Air and Space Port 90 miles north of Los Angeles. The plane carries the LauncherOne rocket Earth Observation data could represent a billion-dollar opportunity for Africa

Earth Observation [EO] data provides a billion-dollar opportunity for economies on the African continent, one that could create jobs and build new resilience after COVID-19.
The newly released report Unlocking the Potential of Earth Observation to address Africa's critical challenges lays out the multiple economic benefits from EO data. The report was written in collaboration with Digital Could we harness energy from black holes

A remarkable prediction of Einstein's theory of general relativity - the theory that connects space, time, and gravity - is that rotating black holes have enormous amounts of energy available to be tapped.
For the last 50 years, scientists have tried to come up with methods to unleash this power. Nobel physicist Roger Penrose theorized that a particle disintegration could draw energy from
