Theoretical study suggests huge lava tubes could exist on moon


Lava tubes large enough to house cities could be structurally stable on the moon, according to a theoretical study. The volcanic features are an important target for future human space exploration because they could provide shelter from cosmic radiation, meteorite impacts and temperature extremes. Lava tubes are tunnels formed from the lava flow of volcanic

NASA’s Hubble Observations Suggest Underground Ocean on Jupiter’s Largest Moon

In this artist’s concept, the moon Ganymede orbits the giant planet Jupiter. NASA’s Hubble Space Telescope observed aurorae on the moon generated by Ganymede’s magnetic fields. A saline ocean under the moon’s icy crust best explains shifting in the auroral belts measured by Hubble.

NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water on Earth’s surface.  Identifying liquid water is crucial in the search for habitable worlds beyond Earth and for the search of life as

Is there organic matter on Mars?

Organic matter recently detected by NASA’s robotic rover Curiosity is probably not due to contamination brought from Earth as researchers originally thought. A team of German and British scientists led by geoscientist Prof. Dr. Frank Keppler from Heidelberg University now suggests that the gaseous chlorinated organic compound- chloromethane — recently found on the Red Planet

There are some 100 million other places in the Milky Way galaxy that could support complex life, according to new research by astronomers. They have developed a new computation method to examine data from planets orbiting other stars in the universe. Their study provides the first quantitative estimate of the number of worlds in our

Coldest star in space discovered

Coldest star in space

A ‘brown dwarf’ star that appears to be the coldest of its kind — as frosty as Earth’s North Pole — has been discovered by astronomers. The object’s distance at 7.2 light-years away, making it the fourth closest system to our Sun. “It is very exciting to discover a new neighbor of our solar system
