Strong winds power electric fields in the upper atmosphere

Added: 30.11.2021 2:17 | 33 views | 0 comments

Using observations from NASA's ICON mission, scientists presented the first direct measurements of Earth's long-theorized dynamo on the edge of space: a wind-driven electrical generator that spans the globe 60-plus miles above our heads. The dynamo churns in the ionosphere, the electrically charged boundary between Earth and space. It's powered by tidal winds in the upper atmosphere that are faster than most hurricanes and rise from the lower atmosphere, creating an electrical environment that can affect satellites and technology on Earth.

Ultrahot Gas Giant Found Circling TOI-2109

Added: 29.11.2021 19:12 | 32 views | 0 comments

With an extremely short orbital period of 0.67 days (16 hours), the newly-discovered ultrahot Jupiter - named TOI-2109b - has the shortest orbital period among all known extrasolar gas giants. TOI-2109b was initially identified by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. Its planetary nature was then confirmed through radial-velocity measurements using several ground-based telescopes. [...]

Hubble Spots Herbig-Haro Object in NGC 1977

Added: 26.11.2021 18:18 | 91 views | 0 comments

Astronomers using the NASA/ESA Hubble Space Telescope have observed HH 45, a Herbig-Haro object embedded in the nebula NGC 1977. Herbig-Haro objects are small bright patches of nebulosity associated with newborn stars. They are formed when gas ejected by young stars collides with clouds of gas and dust nearby at high speeds. “Herbig-Haro objects occur [...]

New research provides clues to developing better intranasal vaccines for COVID-19 and flu

Added: 25.11.2021 17:53 | 6 views | 0 comments

While gut microbiota play a critical role in the induction of adaptive immune responses to influenza virus infection, the role of nasal bacteria in the induction of virus-specific adaptive immunity is less clear. New research explores the role of nasal bacteria and provides clues to developing better intranasal vaccines for flu and COVID-19.
