Detecting life’s influence on planetary atmospheres

An artist’s impression of a habitable exoplanet. Seasonal changes and the presence of disequilibrium gases in such a planet’s atmosphere could indicate the existence of life there.

Biosignatures that vary in time and atmospheric gases that shouldn’t exist without life to replenish them could be two possible ways to detect life on exoplanets. Finding any life that might exist on other planets is extremely challenging. Even in our own Solar System, where we can send probes and orbiters to

Incredible Discovery of 44 Exoplanets After Technical Fault

Discovery Exoplanets

Scientists have found a mammoth 44 planets beyond our solar system in one go using data from the Kepler space telescope and others. These surveys usually find batches of fewer than a dozen planets.What’s more, Kepler only gathered this data after a technical problem reduced engineers’ control of the telescope back in

Exoplanets could easily survive in double- and triple-star systems

Exoplanets

Over 3,700 exoplanets have been found lurking around our universe, and although each has its own unique set of characteristics, the vast majority have one thing in common: they orbit a single star. Researchers once believed that it would be near impossible for planets to survive outside of single-star systems,
