A new analysis of data from the 1978 Pioneer Venus mission, by researchers at Cal Poly Pomona, finds evidence not only for phosphine, but also possible chemical disequilibrium in Venus’ atmosphere, an additional possible sign of biological activity.
NASA’s Juno spacecraft – whose mission in orbit around Jupiter was recently extended to 2025 – has been used to discover a rapidly expanding auroral ring at the very fringes of the Jovian magnetosphere.
An international team of astronomers has mapped a piece of the cosmic web without using bright quasars for the first time. They did it by turning a powerful instrument to a single region of the sky for hundreds of hours.
Data from ESA’s Gaia star-mapping satellite have revealed tantalizing evidence that the famous V-shaped Hyades – nearest star cluster to our sun – is being disrupted. The culprit may be a suspected population of dark matter sub-halos. Wow!
Comet 2I/Borisov is the 2nd known object to pass near our sun from outside our solar system. Its 2019 pass near our sun might have been its first-ever interaction with a star. If so, it’s among the most pristine, or unspoiled, objects yet known.
