A new study of data from NASA’s bountiful Cassini mission shows that Titan’s largest methane sea, Kraken Mare, is at least 1,000 feet – 300 meters – deep near its center. That’s plenty of room for a future robotic submarine to explore. Source: https://earthsky.org/space/titans-largest-sea-kraken-mare-is-1000-feet-deep…

Precision measurements of intracluster light suggest possible link to dark matter
A combination of observational data and sophisticated computer simulations have yielded advances in a field of astrophysics that has languished for half a century. The Dark Energy Survey, which is hosted by the U.S. Department of Energy’s Fermi National Accelerator Laboratory, has published a burst of new results on what’s called intracluster light, or ICL, a faint type of light found…
Update on the 7 Earth-sized planets orbiting nearby TRAPPIST-1
A new study of the seven Earth-sized exoplanets around TRAPPIST-1 indicate that all 7 planets are extremely similar to each other in makeup, but potentially quite different from Earth. Source: https://earthsky.org/space/7-trappist-1-planets-similar-composition-unlike-earth…
What do redshifts tell astronomers?
A redshift reveals how an object is moving in space and enables astronomers to discover otherwise-invisible planets and the movements of galaxies, and to uncover the beginnings of our universe. Source: https://earthsky.org/astronomy-essentials/what-is-a-redshift…
NASA “mole’s” attempts to dig into Mars failed. What’s next?
The mission team for NASA’s InSight lander called off its attempts to try to dig deeper into Mars with the heat probe known as “the mole.” Meanwhile, the rest of the mission gained an extension to December 2022.

Oldest carbonates in the solar system
A meteorite that fell in northern Germany in 2019 contains carbonates which are among the oldest in the solar system; it also evidences the earliest presence of liquid water on a minor planet. The high-resolution Ion Probe—a research instrument at the Institute of Earth Sciences at Heidelberg University—provided the measurements. The investigation by the Cosmochemistry Research Group led by Prof. Dr….
Striped brown dwarf looks a lot like Jupiter
The surface features of brown dwarfs – objects midway in mass between planets and stars – can’t be seen. But researchers have found a way to reveal Jupiter-like stripes and bands in the atmosphere of the closest brown dwarf, Luhman 16B.

Google Employees Try Baking Recipes Created by AI
“Behold the cakie: It has the crispiness of a cookie and the, well, ‘cakiness’ of a cake.” So says a triumphant blog post by Google Cloud’s developer advocate and an applied AI Engineer for Google’s Cloud AI. “We also made breakies, which were more like fluffy cookies, almost the consistency of a muffin” (or bread). Food and Wine explains the project…
2020 Was Second-Hottest Year On Record, NOAA Says
An anonymous reader quotes a report from NBC News: Data released Thursday by the National Oceanic and Atmospheric Administration, or NOAA, showed that 2020 now ranks as the second-hottest year, with average temperatures hitting 58.77 degrees Fahrenheit — a mere 0.04 degrees cooler than 2016, which holds the record. The Northern Hemisphere experienced its hottest year on record, surpassing the 20th…
2020 tied for warmest year on record
2020 was Earth’s hottest year in the 140-year record, effectively tying 2016, the previous record-holder. Source: https://earthsky.org/earth/2020-tied-for-warmest-global-year-on-record…
