Some Sun-like stars are known for their ability to ingest large amounts of the rocky material from which "terrestrial" planets like Earth, Mars and Venus are made. New research on these "Earth-eater" stars may provide scientists with clues about the formation of planets as well as assist in the ongoing search for Earth-like exoplanets, according to astronomers.
A NASA spacecraft recently spotted a square-shaped "hole" formed by solar wind on the surface of the Sun.
Earth's mantle under Antarctica is moving at such a rapid rate it is changing the shape of the land, a new study published in the journal Earth and Planetary Science Letters explained.
The Moon was once rocked by a violent collision that eventually led to the tilt in its present orientation, according to new research published in the journal Nature Geoscience.
NASA scientists have successfully replicated, here on Earth, the processes that form interstellar dust in the atmosphere of a red giant star.
The newly discovered "hypervelocity star" may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious dark matter surrounding the galaxy, astronomers report.
Scientists are worried about Mars invaders of a different kind. These newly feared foes come in the form of microorganisms from Earth, and new research shows that they could potentially contaminate the Red Planet should we ever successfully make the trek there.
Volcanic eruptions that have been spewing over the last 14 years may be partially responsible for the cooling of planet Earth and slowing down the effects of global warming, a new study published in Nature Geoscience suggests.
A small, bus-sized asteroid passed within 186,000 miles (300,000 kilometers) of Earth - closer than the Moon - on Saturday morning, but posed no threat to our planet, Space.com reported.
Incoming asteroids slam into the Earth's atmosphere surprisingly often, some of them as powerful as nuclear bombs, a new time-lapse video illustrates.
Astronomers stumbled upon an "upside-down planet" that offers a new method for studying binary star systems.
Scientists have uncovered evidences that suggest that snow and precipitation may have been a common occurrence in Mars at some point in the past.
Salmon use the Earth's magnetic field to navigate in open water as they locate their river of origin to breed.
A small near-Earth asteroid called 2012 DA14 will pass very close to Earth Feb. 15, NASA officials said.
