Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light-years from Earth. The planet was discovered in data from NASA’s Kepler Space Telescope. Continue reading Artificial Intelligence, NASA Data Used to Discover Eighth Planet Circling Distant Star
HAPPY NEW YEAR from the depths of outer space! While you were getting ready for your holiday vacation, NASA’s space probes were hard at work gathering awesome photos for you. Like Juno, the little spacecraft capturing the Earth-sized tempests while orbiting Jupiter.
Not to scare you, but you’re getting hit with radiation constantly. First, there’s just regular old light (yep, that’s a kind of radiation). Then there are low levels of higher energy radiation like the kind in nuclear reactors, including particles coming out of the soil and off of bananas. But the highest-energy radiation is the weirdest stuff. It’s literally out of this galaxy.
A star 5,000 light-years from Earth is the closest thing to a perfect sphere that has ever been observed in nature, a new study reports.
In recent months, there’s been growing evidence that Pluto is hiding a liquid water ocean beneath its frozen surface. New models by researchers at Brown University support this hypothesis, and take it one mind-boggling step further: Pluto’s ocean may be more than 100 kilometers (62 miles) deep.
Satellites such as the Kepler have been working overtime to uncover hundreds of new planets in our galaxy. But how did we first discover the planets in our local volume of space? Here are the stories of how astronomers living hundreds of years ago discovered each planet in our solar system.
