Recently, NASA’s Kepler space telescope discovered the most Earth-like planet yet! Is it really just like us, or should we maybe dial down our excitement?
Astronomers said Thursday they had found a planetary system with three super-Earths orbiting a bright, dwarf star -- one of them likely a volcanic world of molten rock.
Thursday was a red letter day for exoplanet astronomers -- it was the day that marked the announcement of the discovery of Kepler-452b, an alien world that possesses more Earth-like traits than any exoplanet discovered before it.
Although our solar system doesn't contain gas giants with thick atmospheres enriched with helium, observations by NASA's Spitzer Space Telescope suggests the galaxy may be strewn with these planetary oddities.
Earth is in what's called the habitable zone. It's far enough from the sun that it doesn't get fried, and close enough that it gets the best of its warmth. We like to think we're special for this, but it turns out we might be pretty run of the mill.
A study based on 151 multi-planetary systems found by NASA's Kepler space telescope shows that most have a planet -- or two or three.
Astronomers have found an ancient, more compact version of our solar system, which could have implications for the search of extraterrestrial life.
NASA's Kepler spacecraft has discovered its 1,000th alien planet, further cementing the prolific exoplanet-hunting mission's status as a space-science legend.
