Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden... biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell University research.

Harsh ultraviolet radiation from red suns, once thought to destroy surface life on planets, might help... uncover hidden biospheres as they glow. That neon-like glimmer is a star-induced gleam called biofluorescence, which could turn distant exoplanets into the black-light posters of outer-space, according to new Cornell research, published Aug. 13 in Monthly Notices of the Royal Astronomical Society "Biofluorescent Worlds II: Biological Fluorescence Induced by Stellar UV Flares, a New Temporal Biosignature," Astronomers seeking life on distant planets may want to go for the glow. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover...

Although solar physics is one of the most mature branches of astrophysics, the sun confronts researchers with a large number of outstanding fundamental problems. These problems include the... determination of the structure and dynamics of the solar atmosphere, the magnetic field evolution in the chromosphere and corona, coronal heating, the physics of impulsive energy release, energetic particle acceleration and transport, the physics of coronal mass ejections (CMEs) and shocks, as well as the solar origin of space weather drivers.
Since NASA's Parker Solar Probe launched on Aug. 12, 2018, Earth has made a single trip around the sun--while the daring solar explorer is well into its third orbit around our star. With two close... passes by the sun already under its belt, Parker Solar Probe is speeding toward another close solar approach on Sept. 1, 2019.

Last week marked five years since ESA's Rosetta probe arrived at its target, a comet named 67P/Churyumov-Gerasimenko (or 67P/C-G). Tomorrow, 13 August, it will be four years since the comet, escorted... by Rosetta, reached its perihelion--the closest point to the sun along its orbit. This image, gathered by Rosetta a couple of months after perihelion, when the comet activity was still very intense, depicts the nucleus of the comet with an unusual companion: a chunk of orbiting debris (circled).
