Astronomers Begin Woldwide Observations of 'Unusual' Star as SETI Listens for Alien Signals

Astronomers have begun a close-up study of the unusual star KIC 8462852 in the hopes of explaining Kepler's enigmatic observations. To that end, the American Association of Variable Star Observers recently issued a call to the astronomical community worldwide for more detailed observations, while the SETI Institute has began searching for possible radio signals of artificial origin in KIC 8462852's vicinity.

Planetary debris disks, or protoplanetary disks, are some of the most interesting phenomena in astronomy – these giant clouds of dust and gas surrounding young stars are the birthplaces of new planets. Now, astronomers […]

Planets Around Red Dwarf Stars Could Be More Life-Friendly Than Previously Thought, According to New Study

An artist’s concept of a hypothetical terrestrial exoplanet with two moons orbiting inside the habitable zone of a red dwarf star. New research has shown that such planets could under the right conditions generate their own magnetic field, which could render them potentially habitable. Image Credit: D.

Exactly two years from today, on Aug. 21, 2017, a rare total solar eclipse will be seen again in the skies of the […]

The Early Solar System Could Have Hosted a Fifth Giant Planet, According to New Study

Artist’s impression of a rogue gas giant planet, free-floating in interstellar space. According to a new study, the early Solar System hosted a fifth gas giant planet besides Jupiter, Saturn, Uranus, and Neptune, which was eventually ejected into interstellar space through the gravitational interactions with the rest of the Solar System’s giant planets. Image […]

The Coming of the Cosmic Old Age: New Survey Finds the Universe's Energy Output Is Decreasing With Time

A composite image of a galaxy as seen in different wavelengths by the GAMA survey. The results of the survey, which studied more than 200,000 galaxies in the local Universe, revealed that the latter’s total energy output has decreased by at least 50 percent during the last 2 billion years.

Artist’s conception of the Venus Landsailing Rover. It would use advanced circuits which could survive longer than previous landers in the extreme surface conditions. A “sail” on top would help to move the rover on the surface using wind, a technique known as landsailing. Image Credit: NASA GRC

In what may be a significant […]
