Fried egg nebula: The European Southern Observatory's Very Large Telescope has spotted a massive yellow hypergiant star surrounded by a dusty double shell, prompting astronomers to think of breakfast.
Super-Earth: The newfound haul of alien planets includes 16 super-Earths, which are potentially rocky worlds that are more massive than our planet. One in particular has captured astronomers' attention because it orbits at the edge of its star's habitable zone, suggesting conditions could be ripe to support life.
For a planet to support life, it faces long odds: It has to be the right size, right composition, and right distance from its star. On Monday astronomers announced a trove of new planet 'candidates.'
Scientists seeking an astronomical first – discerning the atmospheric composition of a 'super Earth' exoplanet – have now learned enough to rule out one leading theory.
For the first time, scientists have found a solar system that was not formed in the Milky Way galaxy. What's more, the planet is in danger of being eaten by its host star.
Astronomers, aiming a ground-based telescope at a target spotted by the Hubble in space, confirm the find as the oldest galaxy so far. Its light was emitted at a time when hydrogen and helium fog still filled the universe.
Gliese 581g, a newly discovered, first-of-its-kind planet thought to exist in its star's habitable zone, might just be 'noise,' astronomers say.
