Finding life beyond Earth has been a major project for scientists across the world. But where exactly should researchers point these telescopes? Scientists are now comparing and ranking exoplanets to determine which ones most likely host life.
NASA has revealed its five science selections for refinement during the next year as a first step in choosing one or two missions for flight opportunities as early as 2020.
Earth-like plants may actually have magnetic fields, which may aid chances for life. Scientists have discovered that these planets orbiting close to small stars have magnetic fields that protect them from stellar radiation and help maintain safe surface conditions.
Hot Jupiters, which are gas giants that orbit close to their star, largely remain mysterious. Now, they've found that these planets may only take a few million years to migrate close to their newly formed star.
Nearby red dwarves could reveal a bit more about planet formation.
When it comes to finding habitable planets, it may depend on a rocky planet's "air conditioning system." Scientists have found that some exoplanets that permanently face their sun with the same side could, potentially, be habitable.
Astronomers are taking a closer look at the birth of a planetary system.
There may be a new tool to detect life on alien planets. Scientists have received fresh clues as to how nitrogen could be used to detect life on other planets.
Could aliens have started life on Earth? That's a good question and now, researchers are saying it's possible.
Could aliens be trying to contact Earth? Researchers have found bursts of radio waves flashing across the sky that seem to follow a mathematical pattern.
Scientists have discovered a Jupiter-like planet within a young solar system that may actually tell researchers a bit more about how planets formed around our own sun.
