Is There Alien Life on Dwarf Planet, Ceres?

Is There Alien Life on Dwarf Planet, Ceres?

     SCIENTISTS have discovered an abundance of water ice on the dwarf planet Ceres, suggesting it could potentially be home to alien life.

The tiny sub-planet, which is found in the asteroid belt situated between Mars and Jupiter, has been found to have water ice on its crust, which points to more beneath the surface.

The study, published in the journal Nature Astronomy, shows that Ceres is 10 per cent water ice – which could point to the dwarf planet either currently being habitable, or was once habitable, experts say.

The discovery makes it one of many extraterrestrial bodies that has, or has had, water on it, including Mars, Saturn’s moons Europa and Enceladus, Jupiter’s moon Ganymede and another dwarf planet in Pluto.

Most scientists agree that the location of the water on the sub-planet massively increases the chances of finding life.

Ceres' Mysterious Bright Spots Mysteriously Change | VIDEO

Ceres' Mysterious Bright Spots Mysteriously Change

     When NASA’s Dawn mission witnessed Ceres’ weird bright spots up-close for the first time, planetary scientists were baffled. What material could produce such a bright feature on an otherwise grey surface? Now, a year since the probe arrived in orbit around the dwarf planet, scientists may be closing in on an answer.

However, it’s not Dawn that has found the latest clue as to what these bright patches could be; it was a powerful observatory on Earth that noticed very slight changes as Ceres’ surface is gently heated by the sun.

The bright spots in question are mainly clustered inside a large crater called Occator. Now that Dawn is in its lowest mapping orbit around the small world nestled in the Main Asteroid Belt (between the orbits of Mars and Jupiter), zipping across the cratered landscape at an altitude of only 240 miles, it has captured wonderfully detailed observations of the crater’s floor. The bright feature is actually a cluster of bright spots with diffuse, almost powder-like material surrounding the brightest patches.

The leading theory, so far, is that it’s an icy material such as water ice, but some kind of mineral deposit is also a possibility. Now, with the help of the HARPS spectrograph attached to the ESO 3.6-meter telescope at La Silla, Chile, it seems the ice theory has just become a whole lot stronger. [...]

Amazing Close-Up of Mars' Mysterious South Pole 2015
The icy south pole of Mars takes center stage in this amazing close up from a larger photo of the Martian south pole and cratered Hellas Basin region captured by the European Space Agency's Mars Express orbiter.

      A newly released photo provides a great look at Mars' seldom-seen South Pole.

The swirling white dot toward the bottom of the photo, which was taken by the European Space Agency's Mars Express spacecraft, is the Red Planet’s south polar ice cap. The cap is composed of both frozen water and frozen carbon dioxide, and it changes shape with Mars' seasons.

In 2004, Mars Express confirmed that the south polar cap contains water ice, according to the European Space Agency (ESA). [...]

Enormous Ice sheet Found on Mars | VIDEO

Massive Ice sheet Found on Mars

     Ali Bramson knew she was onto something when she spotted a "crazy looking crater" on the face of Mars.

Trying to explain the crater's strange shape, Bramson, a graduate student in the University of Arizona's Lunar and Planetary Laboratory (LPL), and her colleagues zeroed in on the fact it was terraced, rather than bowl-shaped like most craters of this size.

Terraces can form when there are layers of different materials in the planet's subsurface, such as dirt, ice or rock.

In this case, there was ice - and lots of it. Beneath the surface, they discovered an enormous slab of water ice, measuring 130 feet thick and covering an area equivalent to that of California and Texas combined. The ice was the result, the authors wrote, of snowfall "which can most easily explain the thickness and widespread nature of the excess ice observed."

To locate the ice, the researchers turned to the Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment operated out of LPL. [...]
