NASA sends rovers to Mars to photograph the landscape and operate scientific experiments to understand the habitat for humans or other kinds of life. One of those future rover missions may host the Martian Aqueous Habitat Reconnaissance Suite (MAHRS), a set of 5 instruments that can take surface measurements in the search for habitable environments.

Developed at NASA Glenn in partnership with the University of Michigan, MAHRS is specifically focused on searching for wet brine environments in the shallow subsurface of Mars. “Brine environments are where you would look for life,” says Project Manager Dan Vento...

The world’s largest radio telescope began searching for signals from stars and galaxies and, perhaps, extraterrestrial life Sunday in a project demonstrating China’s rising ambitions in space and its pursuit of international scientific prestige. Beijing has poured billions into such ambitious scientific projects as well as its military-backed space program, which saw the launch of China’s second space station earlier this month.

Ever since NASA’s New Horizons spacecraft flew by Pluto last year, evidence has been mounting that the dwarf planet may have a liquid ocean beneath its icy shell. Now, by modeling the impact dynamics that created a massive crater on Pluto’s surface, a team of researchers has made a new estimate of how thick that liquid layer might be. The study, led by Brown University geologist Brandon Johnson and published in Geophysical Research Letters, finds a high likelihood that there’s more than 100 km of water beneath Pluto’s surface...

This image by Hubble shows the colorful “last hurrah” of a star like our sun. The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star’s remaining core. Ultraviolet light from the dying star makes the material glow. The burned-out star ie white dwarf, is the white dot in the center. Our sun will eventually burn out and shroud itself with stellar debris, but not for another 5 billion years.

Our Milky Way Galaxy is littered with these stellar relics, ie planetary nebulae. The objects have nothing to do with planets...
