Superflares may be less harmful to exoplanets than previously thought, study shows
Astronomers have long suspected that superflares, extreme radiation bursts from stars, can cause lasting damage to the atmospheres — and thus habitability — of exoplanets. A new study published in the Monthly Notices of the Royal Astronomical Society reports that they pose only a limited danger to planetary systems.

Astronomers document the rise and fall of a rarely observed stellar dance
Astronomers have catalogued 126 years of changes to a binary star system called HS Hydrae. Analyzing observations from astro-photographic plates in the late 1800s to TESS observations in 2019, they show that the two stars in HS Hydrae began to eclipse each other starting around a century ago, peaking in the 1960s. The degree of eclipsing then plummeted over the course of just a half century, and will cease around February 2021.
