With several new discoveries this week from space, we decided to take a gander at what exactly is going on in our solar system right now. Here’s a breakdown of the biggest discoveries for the last couple of weeks, according to Quartz and Space.com.

Ripples in Saturn’s rings

The mysterious innards of this Gas Giant are slowly being uncovered due to unusual ripples in Saturn’s rings. The rings, which are mostly made out of rock and ice, have all kinds of stuff going on including waves that ricochet outward due to the gravitational pull of Saturn’s 62 moons. This is all normal. The kicker here though is that for some reason, there is a set of waves moving inward. This set of waves moving inward insinuates that there is something moving inside of the rings. Researchers first noticed these ripples in the ‘90s but they still haven’t figured it out.

“The one thing that might produce this [series of waves] is that some sort of disturbance inside Saturn itself is spinning around with a period that’s less than seven hours,” Phillip Nicholson, a planetary scientist at Cornell University in New York, told Space.com.

Water on Mars — is it habitable?

The news went crazy after NASA announced that they have discovered water on Mars. The new discovery sparked the question of whether or not Mars would ever be habitable. NASA answered some popular questions in an interview with Quartz. While this has not been proven impossible, there are a few things about the new discovery that you should know. NASA has not seen liquid water on Mars. If there is, it’s not flowing. It isn’t clear where the water is coming from yet, but so far there are two options — the salts are soaking up water from the atmosphere, or it’s from below the surface. The rover can’t access the areas that water exists in because they are on steep slopes and the chance that Earth life could contaminate it is too great. NASA is hoping to have humans in the vicinity of Mars in the early 2030s and to the surface later that decade.

Solar Flare Issues

According to Space.com, an intense solar flare burst from a sun spot and took out low-frequency radio communications over South America and the Atlantic Ocean earlier last week. The explosion released extreme ultraviolet radiation that covered Earth and supercharged the atmosphere. There is a chance of more solar flares from that spot in the future as well as from another sun spot that is similar but will have greater effects.

New Images Show Enormous Canyon System on Pluto’s Big Moon Charon

During NASA’s New Horizons historic flyby in July, images of Pluto’s big moon Charon revealed a more than 1,000 mile wide chasm on the moon’s surface. The mission’s team members put the images together in a video which was released the past weekend. The chasm is at least four times longer than the Grand Canyon and twice as deep in some areas.

Dwarf Planet Ceres shows bright spots

NASA’s Dawn spacecraft has remapped Ceres and portrayed its pyramid-shaped mountain and bright spots in a new light. The mountain rises about four miles into space from Ceres’ surface. The new maps also show the 56-mile-wide Occator crater, which is home to the most luminescent of Ceres’ bright spots.
