Enormous X-ray bubbles balloon from the center of the Milky Way
Newly found X-ray bubbles are even bigger than the previously known gamma-ray bubbles. Both sets of bubbles extend above and below the plane of the galaxy.
Citizen Astronomers Across the Globe Partner for World-Record Research on a Near-Earth Asteroid
Twenty-six citizen astronomers recently detected and modeled a near-Earth asteroid (NEA), making them the first planetary defense team of citizen astronomers.
Spiders in space: without gravity, light becomes key to orientation
In a 2011 spiders-in-space experiment, researchers studied webs the spiders spun both with and without light, and watched how the spiders oriented themselves.
Airless Exoplanet’s Mantle Could Flow in Halves
At AGU’s Fall Meeting, researchers explained how they used extreme surface temperatures to find that exoplanet LHS 3844b’s mantle could flow in a half-and-half pattern.
A technique to sift out the universe’s first gravitational waves
In a new paper, researchers have developed a potential technique for separating out sounds of nearby gravitational wave sources and sort through the background noise to detect those gravitational waves that originated in the early universe.
SpaceX launches twenty-first Commercial Resupply Services mission
Our last launch of the week was a SpaceX Falcon 9. On December sixth at 16:17 UTC, CRS-21 started its journey to the International Space Station from historic LC-39A at Kennedy Space Center, Florida.
China launches Gaofen-14, another Earth-observation satellite
On December fifth at 03:58 UTC, China launched a Long March 3B from LC-3 at the Xichang Satellite Launch Center in southwestern China. Onboard was Gaofen-14, the next in China’s series of high-resolution optical imaging satellites.
Second successful launch of Soyuz-2 rocket in 24 hours
At 01:14 UTC on December 3rd, a Russian Military Soyuz-2.1b was launched from LC-43/3 at the Plesetsk Cosmodrome in northern Russia.
Key building block for organic molecules discovered in meteorites
A cooperative Japanese-US team of scientists has found an important building block for organic molecules, hexamethylenetetramine (HMT), in three different carbon-rich meteorites.
A Better Understanding of How the Sun Bends Light
We are about five days away from a total solar eclipse that will be passing over South America. We expect there to be images from scientists who are looking to recreate Eddington’s amazing images of stars appearing in distorted locations thanks to the light bending actions of the Sun’s gravity.
