First, the paper
suggests that there could be habitable
planets around white dwarfs — during the dead - end stage that comes after the inferno of the

suggests that habitable - zone super-Earth
planets (where liquid water could exist and making them possible candidates to support life) orbit around at least a quarter of the
red dwarfs in the Sun's own neighbourhood.

Red Planet, it must be very rare — or so an unexploited energy source in the atmosphere
suggests.
Now, new research in the journal Nature Geoscience
suggests that an ancient collision could have sent a ring of debris containing at least 100 small moons into orbit around the
Red Planet, which eventually coalesced into Phobos and Deimos — Mars's two current moons.
Further afield, she and Ballentine point out that the rocks from the Canadian mine are similar in chemistry and age to rocks in the subsurface of Mars —
suggesting fertile conditions could persist inside the
Red Planet for millions of years.
While not necessarily hard evidence of life on the

Stromatolites at El Tatio, Chile
suggest the structures found in the

NASA Mars rover drills into rock that
suggests some water in the
Red Planet's past was highly acidic.
Molten glass created in impacts on Mars could have captured and preserved signs of ancient life on the
Red Planet as it cooled, researchers

Evidence gathered by rovers and satellites such as Curiosity and the Mars Reconnaissance Orbiter
suggests that, billions of years ago, the
Red Planet was once covered in lakes and oceans, and that it had a thicker atmosphere.
But new research
suggests that life within these systems may be limited, due to the stiflingly hot atmospheres on Earth - sized
planets that orbit the
red dwarfs.
Discouragingly, a new study published in The Astrophysical Journal
suggests that
planets in orbit around
red dwarfs may be subject to tremendously powerful and frequent solar flares, making it difficult — if not impossible — for life to emerge in such systems.
From 1992 to 2003, the decadal ocean heat content changes (blue), along with the contributions from melting glaciers, ice sheets, and sea ice and small contributions from land and atmosphere warming,

PASADENA, Calif. — A new NASA study
suggests if life ever existed on Mars, the longest lasting habitats were most likely below the
Red Planet's surface.
Previous research
suggests that adiabatic quantum computers are especially good at optimization problems, which involve finding the best solution from all feasible solutions, such as the shortest route connecting multiple destinations, or the most stable form of molecules — the former problem could help Mars rovers better explore the
red planet, while the latter could lead to better drugs or catalysts.
