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.
Hunting for alien planets
Kepler has given us a stash of thousands of exoplanets. Now, researchers have pulled twenty from that stash that they say are the most likely to be habitable.
