Ultraviolet Light Archives

A three-dimensional map of stars near the Sun that are close enough to Earth for planets in their habitable zones to be directly imaged using future telescopes, along with an artist’s illustration of such a system. Planets in their stars’ habitable zones likely have liquid water on their surfaces. A study with Chandra and XMM-Newton of some of these stars (shown in blue haloes) indicates those that would most likely have habitable exoplanets around them based on a second condition — whether they receive lethal radiation from the stars they orbit. -- HSCfA

Chandra X-ray Observatory Checks The Habitability Of Exoplanets

by Keith CowingJune 12, 2024June 12, 2024

Using NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton, astronomers are exploring whether nearby stars could host habitable exoplanets, based on whether they emit radiation that could destroy […]

Ultraviolet Light May Be Ultra Important In Search For Life

by Keith CowingAugust 31, 2017

In everyday life, ultraviolet, or UV, light earns a bad reputation for being responsible for sunburns and other harmful effects on humans. However, research suggests that UV light may have […]
