In a recent paper, Harvard University researchers described a new, lower size limit for planets to maintain surface liquid water for long periods of time, extending the so-called Habitable or "Goldilocks’’ Zone for small, low-gravity planets.

Data recorded by NASA's Chandra X-ray Observatory of a neutron star as it passed through a dense patch of stellar wind emanating from its massive companion star provide valuable insight about the structure and composition of stellar winds and about the environment of the neutron

One of the major issues when studying ore deposits formed in surficial or near-surface environments is the relationship between ore-forming processes and bacteria.

For the first time ever, astronomers have detected a 1.3 km radius body at the edge of the Solar System.

Engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, have begun transmitting a new set of commands to the Opportunity rover in an attempt to compel the 15-year-old Martian explorer to contact Earth.

Data captured by ESA’s galaxy-mapping spacecraft Gaia has revealed for the first time how white dwarfs, the dead remnants of stars like our Sun, turn into solid spheres as the hot gas inside them cools down. This process of solidification, or crystallisation, of the material

The strange orbits of some objects in the farthest reaches of our solar system can instead be explained by the combined gravitational force of small objects orbiting the Sun beyond Neptune, say researchers.

Microbes that thrive in some of the most extreme places on Earth have discovered another cozy place to live -- inside homes across the United States.

Two new species of fungi have made an appearance in a rapidly melting glacier on Ellesmere Island in the Canadian Arctic, just west of Greenland.
