Observations suggest sun-like stars emit superflares once per century

A new study published in Science examines the frequency of solar superflares by analyzing data from 56,450 sun-like stars observed by NASA’s Kepler space telescope. These superflares, which release immense energy, were detected as sharp brightness peaks. By studying these stars, researchers estimate that a sun-like star experiences a superflare approximately once every century, Phys.org has reported. The study, which accounts for errors and non-sun-like stars, offers … Continue reading Observations suggest sun-like stars emit superflares once per century

NASA’s Ingenuity helicopter could live on as a weather station for 20 years

Atmospheric analysis shows Venus never had Earth-like life, scientists say

Scientists have debunked the theory that Venus ever hosted Earth-like life by analyzing the planet’s atmosphere. Research suggests Venus has always been dry, with volcanic eruptions emitting little water, indicating the planet never had oceans of liquid water. This challenges the idea that Venus was once habitable, as some previously thought. While Venus may still hold some potential for life in its acidic clouds, the … Continue reading Atmospheric analysis shows Venus never had Earth-like life, scientists say
