These dynamic regions are sources of solar flares and coronal mass ejections, powerful explosions that can affect spacecraft and disrupt power grids and communications here on Earth.

This spectacle will mark the first of four consecutive total lunar eclipses, a series known as a tetrad. A lunar eclipse occurs when the moon dips behind Earth’s shadow. Most eclipses are partial, meaning only portions of the moon are hidden from the sun. But sometimes the moon, Earth, and sun perfectly align so that the entire moon is shielded from the sun’s rays. When this happens, wayward beams of sunlight filter through Earth’s atmosphere, coloring the moon a fiery red, resulting in a total eclipse. While a tetrad itself isn’t rare, NASA scientists say that its visibility across the entire United States is unique.

The number practically doubles the list of planets known to humanity. Kepler spotted 3,600 potential planets within the first two years of operation by detecting slight dips in the brightness of more than 100,000 nearby stars. The challenge, however, is distinguishing the real planets from the fakes, a laborious process that involves sifting through the candidate planets, one by one. But by employing a new method that can verify multiple planets at once, researchers were able to speed up their search. About 95 percent of the newly discovered worlds are smaller than Neptune, with four orbiting within the habitable zones of their host stars. The findings suggest that small, Earth-like planets may be more abundant in our galaxy than previously thought.

Locked in a perpetual tug of war between the imposing gravity of Jupiter and the smaller, consistent pulls of its neighboring moons, Io’s distorted orbit causes it to flex as it swoops around the gas giant. The stretching causes friction and intense heat in Io’s interior, sparking massive eruptions across its surface.

Us too. But there’s one problem in particular that first needs to be solved: how to get rid of human waste during long-duration missions. Now, new technology being developed aboard the International Space Station by NASA and the French space agency may provide an answer. The key? Water. At a precise temperature and pressure, water reaches a supercritical state where it is neither a liquid nor gas, but something in between. When scientists add water to organic matter such as excrement and raise the slurry to this critical point, it's possible to burn the waste in a reaction which produces byproducts that are both useful and eco-friendly. Even better, after the water returns to its normal state it’s pure enough to drink.
