A warp in the Milky Way linked to galactic collision

When most of us picture the shape of the Milky Way, the galaxy that contains our own sun and hundreds of billions of other stars, we think of a central mass surrounded by a flat disc of stars that spiral around it. However, astronomers know that rather than being symmetrical, the disc structure is warped, more like the brim of a fedora, and that the warped edges are constantly moving around the Student astronomer finds galactic missing matter

Astronomers have for the first time used distant galaxies as 'scintillating pins' to locate and identify a piece of the Milky Way's missing matter.
For decades, scientists have been puzzled as to why they couldn't account for all the matter in the universe as predicted by theory. While most of the universe's mass is thought to be mysterious dark matter and dark energy, 5 percent is 'normal An asteroid "double disaster" struck Germany in the Miocene

By analyzing sediments jostled by ground shaking, researchers have shown that two impact craters near Stuttgart were created by independent asteroid impacts rather than a binary asteroid strike.

China's space probe sends back its first image of Mars
Friday, 05 February 2021 18:20 Write a comment
China's Tianwen-1 probe has sent back its first image of Mars, the national space agency said, as the mission prepares to touch down on the Red Planet later this year.
The spacecraft, launched in July around the same time as a rival US mission, is expected to enter Mars orbit around February 10.
The black-and-white photo released late Friday by the China National Space Administration showed geological features including the Schiaparelli crater and the Valles Marineris, a vast stretch of canyons on the Martian surface.
The photo was taken about 2.2 million kilometres (1.4 million miles) from Mars, according to CNSA, which said the spacecraft was now 1.1 million kilometres from the planet.
Harvard astronomer argues that alien vessel paid us a visit
Friday, 05 February 2021 18:19 Write a comment
Discovering there's intelligent life beyond our planet could be the most transformative event in human history— but what if scientists decided to collectively ignore evidence suggesting it already happened?
That's the premise of a new book by a top astronomer, who argues that the simplest and best explanation for the highly unusual characteristics of an interstellar object that sped through our solar system in 2017 is that it was alien technology.
Sound kooky? Avi Loeb says the evidence holds otherwise, and is convinced his peers in the scientific community are so consumed by groupthink they're unwilling to wield Occam's razor.
Loeb's stellar credentials—he was the longest-serving chair of astronomy at Harvard, has published hundreds of pioneering papers, and has collaborated with greats like the late Stephen Hawking—make him difficult to dismiss outright.

SAN FRANCISCO – The National Oceanic and Atmospheric Administration awarded a $43.8 million space weather contract to L3 Harris Technologies.
Under the five-year, cost-plus contract, Melbourne, Florida-based L3Harris will develop, deploy and operate a command and control system for NOAA’s Space Weather Follow On-Lagrange 1 observatory, scheduled to launch in 2025 on NASA’s Interstellar Mapping and Acceleration Probe.
Op-ed | The FAA and SpaceX

Fifty years ago, Boeing was the gold standard for aviation and aerospace engineering excellence. And the FAA led the world in setting aircraft and airspace safety standards. No longer.
Today, the fate of the SpaceX Starship offers an example of how government oversight agencies can stifle innovation when they are unable to distinguish between innovation and execution and throw roadblocks in front of the single company that has transformed access to space.

Every challenge astronauts will face on a flight to Mars
Thursday, 04 February 2021 14:28 Write a comment
In 1972, the space race officially ended as NASA sent one last crew of astronauts to the surface of the moon (Apollo 17). This was the brass ring that both the US and the Soviets were reaching for, the "moonshot" that would determine who had supremacy in space. In the current age of renewed space exploration, the next great leap will clearly involve sending astronauts to Mars.
This will present many challenges that will need to be addressed in advance, many of which have to do with simply getting the astronauts there in one piece! These challenges were the subject of a presentation made by two Indian researchers at the SciTech Forum 2020, an annual event hosted by the International Academy of Astronautics (IAA), RUDN University, and the American Astronomical Society (AAS).
