Scientists may have found a way to tell if alien worlds have a climate that is suitable for life by analyzing the light from these worlds for special signatures that are characteristic of a life-friendly environment. This technique could reveal the inner edge of a star’s habitable zone, the region around a star where liquid […]

CARBON MONOXIDE DETECTORS COULD WARN OF EXTRATERRESTRIAL LIFE
Carbon monoxide detectors in our homes warn of a dangerous buildup of that colorless, odorless gas we normally associate with death. Astronomers, too, have generally assumed that a build-up of carbon monoxide in a planet’s atmosphere would be a sure sign of lifelessness. Now, a UC Riverside-led research team is arguing the opposite: celestial carbon […]
THANK EARTH’S MAGNETIC FIELD FOR WATER THAT GIVES YOU LIFE
A study by scientists at Australian National University (ANU) on the magnetic fields of planets has found that most planets discovered in other solar systems are unlikely to be as hospitable to life as Earth. Plants and animals would not survive without water on Earth. The sheer strength of Earth’s magnetic field helps to maintain […]
