Impact On Life From The Temporary Breakdown Of Earth's Magnetic Field 42,000 Years Ago
The temporary breakdown of Earth’s magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study co-led by UNSW […]

Statistical Properties Of Superflares On Solar-type Stars: Results Using All Of The Kepler Primary Mission Data
We report the latest statistical analyses of superflares on solar-type (G-type main-sequence; effective temperature is 5100 — 6000 K) stars using all of the Kepler primary mission data, and Gaia-DR2 […]

EvryFlare III: Temperature Evolution and Habitability Impacts of Dozens of Superflares Observed Simultaneously by Evryscope and TESS
Superflares may provide the dominant source of biologically relevant UV radiation to rocky habitable zone M-dwarf planets (M-Earths), altering planetary atmospheres and conditions for surface life. The combined line and […]

Stellar Flares Versus Luminosity: XUV-induced Atmospheric Escape And Planetary Habitability
Space weather plays an important role in the evolution of planetary atmospheres. Observations have shown that stellar flares emit energy in a wide energy range (10^30-10^38 ergs), a fraction of […]

Recently Discovered Planets Not As Safe From Stellar Flares As First Thought
A nearby star, the host of two (and possibly three) planets, was initially thought to be quiet and boring. These attributes are sought-after as they create a safe environment for […]
