Astronomers used radio waves to study conditions in the vicinity of Proxima Centauri, the nearest star to our sun. The results suggest Proxima’s 2 known planets are likely bathed in intense radiation from this star, casting doubt on the planets’ potential for life.

New type of atomic clock could help scientists detect dark matter and study gravity’s effect on time
Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in sync. The best atomic clocks in the world keep time with such precision that, if they had been running since the beginning of the universe, they would only…
A surprising find of fast-moving gas from a young star
Fast-moving gas from a young star – located in a star-forming region 400 light-years away – is giving astronomers insight into how planets form. Source: https://earthsky.org/space/no-lup-surprising-find-outflowing-gas-young-star…
This Robot Can Rap
What if your digital assistant could battle rap? That may sound far-fetched, but Gil Weinberg, a music technologist at the Georgia Institute of Technology, has adapted a musical robot called Shimon to compose lyrics and perform in real time. From a report: That means it can engage in rap “conversations” with humans, and maybe even help them compose their own lyrics….

Searching for sub-eV sterile neutrinos using two highly sensitive detectors
The standard model of particle physics only accounts for 20% of matter in the universe. Physicists have theorized that the remaining 80% is made up by so-called dark matter, which consists of particles that do not emit, absorb or reflect light and thus cannot be directly observed using any existing instruments. …
Phew! Record-smashing 2020 Atlantic hurricane season is officially over
November 30 marked the official end of the record-breaking 2020 Atlantic hurricane season, although more storms are still possible. Why did 2020 have so many storms? And what does climate change have to do with it? Source: https://earthsky.org/earth/record-smashing-2020-atlantic-hurricane-season-official-end…
1% of Farms Operate 70% of World’s Farmland
One percent of the world’s farms operate 70% of crop fields, ranches and orchards, according to a report that highlights the impact of land inequality on the climate and nature crises. The Guardian reports: Since the 1980s, researchers found control over the land has become far more concentrated both directly through ownership and indirectly through contract farming, which results in more…
China Launches Ambitious Mission To Land On Moon and Return Samples To Earth
BeerFartMoron shares a report from CBS News: China launched its most ambitious moon mission yet Monday: a robotic spacecraft expected to land on the lunar surface by the end of the week. The spacecraft is expected to collect about four pounds of rock and soil samples, and return them to Earth next month for laboratory analysis. If successful, the Chang’e 5…
Does Jupiter’s moon Europa have geysers? If so, what’s their source?
If watery plumes do burst from Europa’s surface, they might originate not in the moon’s underground ocean, but instead in pockets of brine trapped in the moon’s crust. If that’s so, it could be a source of frustration for those who want to probe Europa’s ocean for possible life. Source: https://earthsky.org/space/jupiter-moon-europa-plumes-salty-water-in-crust…
