Will Earth-like planets be found to have Earth-like oceans?
For a planetary surface to boast extensive areas of both land and water, a delicate balance must be struck between the volume of water it retains and the capacity of its oceanic basins. Each of these two quantities may vary substantially across the full spectrum of water-bearing worlds. Why the Earth's values are so well balanced is an unresolved and long-standing conundrum.

Newly discovered exoplanet may be best candidate in search for signs of life
An exoplanet orbiting a red dwarf star 40 light-years from Earth may be the new holder of the title 'best place to look for signs of life beyond the solar system.' Using ESO's HARPS instrument, and other telescopes, astronomers discovered a 'super-Earth' orbiting in the habitable zone around the star LHS 1140. This world is larger and more massive than the Earth and has likely retained most of its atmosphere. This makes it one of the most exciting targets for atmospheric studies.

Hazardous asteroid effects ranked from least to most destructive

New method can model chemistry in extreme magnetic fields of white dwarfs
Approximately 10-20 percent of white dwarfs exhibit strong magnetic fields, which can reach up to 100,000 tesla. However, on Earth, the strongest magnetic fields that can be generated using nondestructive magnets are about 100 tesla. Therefore, studying the chemistry in such extreme conditions is only possible using theory and until now has not provided much insight to the spectra accompanying white dwarfs.

Mission control: Salty diet makes you hungry, not thirsty
We've all heard it: eating salty foods makes you thirstier. But what sounds like good nutritional advice turns out to be not true in the long run. In a study carried out during a simulated mission to Mars, an international group of scientists has found exactly the opposite to be true. 'Cosmonauts' who ate more salt retained more water, weren't as thirsty, and needed more energy.

Supermassive black holes found in two tiny galaxies
Astronomers have found two ultra-compact dwarf galaxies with supermassive black holes, the second and third such galaxies found to harbor the objects. Together, the three examples suggest that black holes lurk at the center of most ultra-compact dwarfs, potentially doubling the number of supermassive black holes known in the universe. The tiny galaxies were likely leftovers of larger galaxies stripped of their outer layers after colliding into other, larger galaxies.

Shadow of agas cloud detected in an ancient proto-supercluster
The Suprime-Cam on the Subaru Telescope has been used to create the most-extensive map of neutral hydrogen gas in the early universe. This cloud appears widely spread out across 160 million light-years in and around a structure called the proto-supercluster. It is the largest structure in the distant universe, and existed some 11.5 billion years ago. Such a huge gas cloud is extremely valuable for studying large-scale structure formation and the evolution of galaxies from gas in the early universe, and merits further investigation.

Reading between the lines of highly turbulent plasmas
Plasma, the ionised state of matter found in stars, is still not fully understood. Astrophysicists have long-since sought to develop models that can account for the turbulent motions inside plasma. Turbulences are typically detected through observation of broadened lines due to the Doppler Effect. In a new study, researchers have developed an iterative simulation model that accurately predicts changes to the line shape in the presence of strong plasma turbulence.
