NASA Scientists demonstrate Technique to Improve Particle Warnings that Protect Astronauts

Scientists from NASA and the National Center for Atmospheric Research have shown that data from a ground-based instrument called K-Cor can give scientists early warning of a certain type of incoming space weather that can impact astronauts. This composite image shows a coronal mass ejection, a type of space weather linked to solar energetic particles, as seen from two space-based solar observatories and one ground-based instrument. The image in gold is from NASA's Solar Dynamics Observatory, the image in blue is from the Manua Loa Solar Observatory's K-Cor coronagraph, and the image in red is from ESA and NASA's Solar and Heliospheric Observatory.

Radiation Blasts leave most Earth-like planet Uninhabitable

The planet Kepler-438b is shown here in front of its violent parent star. It is regularly irradiated by huge flares of radiation, which could render the planet uninhabitable. Here the planet's atmosphere is shown being stripped away. Credit: With credit to Mark A Garlick/University of Warwick

The most Earth-like planet could have been made uninhabitable by vast quantities of radiation.The atmosphere of the planet, Kepler-438b, is thought to have been stripped away as a result of radiation emitted from a superflaring red dwarf star, Kepler-438. Regularly occurring every few hundred days, the superflares are approximately 10X more powerful than those ever recorded on the sun and equivalent to the same energy as 100 billion megatons of TNT.

While superflares themselves are unlikely to have a ...
