Astronomers have discovered thousands of exoplanets in our galaxy, the Milky Way, using the Kepler satellite and many of them have multiple planets orbiting the host star.

Habitability of Water Worlds

There are four different stable climate states for pure water atmospheres, as might exist on so-called "waterworlds".

As telescopes of ever-greater power scan the cosmos looking for life, knowing where to look and where not to waste time looking will be of great value.

NASA's Cassini spacecraft has provided scientists the first clear evidence that Saturn's moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth.

In the present study we explore the astrobiological significance of F-type stars of spectral type between F5 V and F9.5 V, which possess Jupiter-type planets within or close to their climatological habitable zones.

NASA will host a teleconference at 11 a.m. EDT on Thursday, March 12, to discuss Hubble Space Telescope's observations of Ganymede, Jupiter's largest moon. These results will help scientists in the search for habitable worlds beyond Earth.

The onset and nature of the earliest geomagnetic field is important for understanding the evolution of the core, atmosphere and
life on Earth.

Simulations by researchers at Tokyo Institute of Technology and Tsinghua University indicate that Earth-like planets are more likely to be found orbiting Sun-like stars rather than lower-mass stars that are currently targeted, in terms of water contents of planets.

In binary star systems, the winds from the two components impact each other, leading to strong shocks and regions of enhanced density and temperature.

As part of a national scientific network 'Pathways to Habitability' the formation of planets and the delivery of water onto these planets is a key question as water is essential for the development of life.
