A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond Neptune, from a class known as trans-Neptunian objects, that is moving in rhythm with the giant planet. This image shows the orbits of all of the objects discovered in the Outer Solar System Origins Survey. The orbit of 2020 VN40 is the thickest one, tilted up and to the left from the orbits of most of the objects. The orbits of the giant planets Jupiter, Saturn, Uranus, and Neptune are the white circles. Credit: Rosemary Pike, CfA
This object, called 2020 VN40, is the first confirmed body that orbits the sun once for every ten orbits Neptune completes.

Scientists have developed a technology that may help humans survive on the moon. In a study published in the journal Joule, researchers extracted water from lunar soil and used it to convert carbon dioxide into oxygen and chemicals for fuel—potentially opening new doors for future deep space exploration by mitigating the need to transport essential resources like water and fuel all the way from Earth.
“We never fully imagined the ‘magic’ that the lunar soil possessed,” said Lu Wang of the Chinese University of Hong Kong, Shenzhen.
“The biggest surprise for us was the tangible success of this integrated approach...

Researchers at MIT and other institutions have identified compounds that can fight off viral infection by activating a defense pathway inside host cells. These compounds, they believe, could be used as antiviral drugs that work against not just one but any kind of virus.
The researchers identified these compounds, which activate a host cell defense system known as the integrated stress response pathway, in a screen of nearly 400,000 molecules...

The hunt for potentially habitable rocky planets in our galaxy has been the holy grail of exoplanet studies for decades. While the discovery of more than 5,900 exoplanets in more than 4,400 planetary systems has been a remarkable achievement, only a small fraction (217) have been confirmed as terrestrial—aka rocky or “Earth-like.” Furthermore, obtaining accurate information on a rocky exoplanet’s atmosphere is very difficult, since potentially habitable rocky planets are much smaller and tend to orbit closer to their stars.
Thanks to next-generation instruments like the James Webb Space Telescope (JWST), exoplanet studies are transitioning from discovery to characterization...
