The background: Ceres, a dwarf planet located in the asteroid belt between Mars and Jupiter, was studied intensely by the Dawn orbiter from March 2015 to November 2018. In its final weeks, the orbiter came as close as 22 miles from Ceres’s surface and collected a tremendous amount of data about the dwarf planet’s chemical composition. Dawn found many sodium chloride deposits on the surface, which scientists thought likely came from liquid that had seeped up onto the surface and evaporated, leaving behind a salty crust.

What’s new: But there still remained a question of exactly how that liquid got there. In a new analysis of the high-resolution images Dawn collected during those last weeks, Italian researchers found that the liquid comes from an underground reservoir of briny water, 25 miles below the surface of the Occator Crater, that could measure hundreds of miles wide. The salts found on the surface are important in helping to maintain liquid water within an environment like Ceres.

Having dropped tantalising hints days ago about an "exciting new discovery about the Moon", the US space agency has revealed conclusive evidence of water on our only natural satellite.

This "unambiguous detection of molecular water" will boost Nasa's hopes of establishing a lunar base.

The aim is to sustain that base by tapping into the Moon's natural resources.

The findings have been published as two papers in the journal Nature Astronomy.

While there have previously been signs of water on the lunar surface, these new discoveries suggest it is more abundant than previously thought. "It gives us more options for potential water sources on the Moon," said Hannah Sargeant, a planetary scientist from the Open University in Milton Keynes, told BBC News.

We once thought of Mars as a dried up husk of a planet with no significant water resources on its surface. After further study, scientists have discovered the Red Planet has vast amounts of water ice, and there may even be some water flowing on its surface. Mars’ water reserves may even be more accessible than we believed. A new analysis of past NASA data points to water ice near the Martian equator where scientists thought it could not exist.

NASA didn’t have to send a new probe to Mars to figure this out. In fact, the instrument used to obtain this data has long since been retired. Scientists reevaluated data from the NASA Odyssey Spacecraft, which was in operation between 2002 and 2009. The goal of this mission was to map the surface of Mars while also looking for evidence of water. It was used to identify landing sites for surface missions, and to this day still acts as a data relay for the Curiosity rover.

Astronomen der US-Raumfahrtbehörde Nasa haben nach eigenen Angaben weitere Anzeichen für die Existenz von Wasserdampf-Geysiren auf der vereisten Oberfläche des Jupiter-Monds Europa entdeckt. Europa, einer der mehr als 50 Monde des Gasgiganten, gilt laut Nasa als einer der "Top-Kandidaten" für die Existenz von Leben außerhalb der Erde.


Europa ist etwas kleiner als der Erdmond und vollständig von Eis bedeckt. Unter dem Eispanzer vermuten Astronomen einen bis zu 100 Kilometer tiefen Ozean, der mehr Wasser enthält als alle irdischen Meere zusammen.
