Harnessing the power of AI to understand warm dense matter
Write a comment
Dresden, Germany (SPX) Jan 29, 2021
The study of warm dense matter helps us understand what is going on inside giant planets, brown dwarfs, and neutron stars. However, this state of matter, which exhibits properties of both solids and plasmas, does not occur naturally on Earth. It can be produced artificially in the lab using large X-ray experiments, albeit only at a small scale and for short periods of time.

Studying the creation and evolution of sulfur-containing compounds in outer space is essential for understanding interstellar chemistry. CS2 is believed to be the most important molecule in comet nuclei, interstellar dust, or ice cores. CS and S2 are the photodissociation fragments of CS2.

TESS discovers four exoplanets orbiting a nearby sun-like star

Boston MA (SPX) Jan 29, 2021
MIT researchers have discovered four new exoplanets orbiting a sun-like star just over 200 light-years from Earth. Because of the diversity of these planets and brightness of their star, this system could be an ideal target for atmospheric characterization with NASA's upcoming James Webb Space Telescope. Tansu Daylan, a postdoc at the MIT Kavli Institute for Astrophysics and Space Research, led

Heidelberg, Germany (SPX) Jan 29, 2021
Scientists have been finding ring-like structures indicating planet formation in the disks surrounding young Sun-like stars for several years. Astronomers led by Nicolas Kurtovic from the Max Planck Institute for Astronomy in Heidelberg, Germany, have now detected similar signals in disks of young very low-mass stars that are considerably smaller and less massive than their counterparts.

Toulouse, France (SPX) Jan 29, 2021
Airbus has been awarded a CLTV (Cis-Lunar Transfer Vehicle) study for a "Moon Cruiser" by the European Space Agency (ESA). According to the study concept (two parallel Phase A/B1), the CLTV is a versatile, autonomous logistics vehicle that could, for example, provide timely and efficient support to NASA and ESA in the implementation of the future Artemis Moon missions.

The year 1986 was shaping up to be the most ambitious one yet for NASA's Space Shuttle Program. The agency's plans called for up to 15 missions, including the first flight from the West Coast launch site at Vandenberg Air Force Base in California. Other important missions included the launch of two planetary spacecraft with very tight launch windows, an astronomy mission to study Halley's Comet,

America's first astronaut, Alan Shepard, took that first suborbital flight of 15 minutes on May 15, 1961. The expected flight time was so short that NASA assumed no toilet facilities would be needed. However, Shepard had to endure several hours in his Mercury capsule before lift-off due to launch delays. You can imagine the results, but it wasn't pretty.

Thick lithosphere casts doubt on plate tectonics in Venus's geologically recent past
Write a comment
At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers has used that ancient impact scar to explore the possibility that Venus once had Earth-like plate tectonics.
For a study published in Nature Astronomy, the researchers used computer models to recreate the impact that carved out Mead crater, Venus's largest impact basin. Mead is surrounded by two clifflike faults—rocky ripples frozen in time after the basin-forming impact. The models showed that for those rings to be where they are in relation to the central crater, Venus's lithosphere—its rocky outer shell—must have been quite thick, far thicker than that of Earth.
