A massive dust storm on Mars that covered one-fourth of planet just a week ago has grown into a global weather event, NASA officials said Wednesday (June 20).

During the 1930s, astronomers came to realize that the Universe is in a state of expansion. By the 1990s, they realized that the rate at which it is expansion is accelerating, giving rise to the theory of "Dark Energy".

The first spacecraft to demonstrate active space debris-removal technologies — such as a harpoon, a net and a drag sail — in orbit has been released from the International Space Station to commence its mission.

Scientists have struggled for millennia to understand human consciousness - the awareness of one's existence. Despite advances in neuroscience, we still don't really know where it comes from, and how it arises.

The Fermi Paradox remains a stumbling block when it comes to the search for extra-terrestrial intelligence (SETI).

By making a strange kind of particle that is its own antiparticle out of a time crystal, physicists aim to develop a quantum computer that's not only more reliable, but far more lightweight than anything currently in the pipeline.

The launch of NASA's troubled James Webb Space Telescope has been pushed back another year, to no earlier than March 2021, as the agency grapples with construction issues.

Quirks in ‘Oumuamua’s path through the Solar System helped researchers solve a case of mistaken identity.

Jeff Bezos' aerospace company Blue Origin has just announced plans to open the ticket booth next year for commercial flights to the edge of space.

Boeing has dreams of a hypersonic passenger plane, and it looks like something straight out of science fiction.

Two exoplanets thought to be similar to Earth apparently are, at least when it comes to climate, researc†Kepler-186f is the first identified Earth-sized planet outside the solar system orbiting a star in the habitable zone. This means it's the pr

Congratulations, it's a gas giant!

All the planets in the Solar System are more or less oriented the same as the Sun, with North and South pointed in the same direction. Not Uranus though. The blue planet's north-south axis is tilted 98 degrees from the Sun's orbital plane - it's pr

Researchers from Montreal's National Institute of Scientific Research (INRS) just published a study in Optica detailing a new approach to invisibility cloaking.

Scientists have identified a key molecule exploited by HIV when the virus infects human cells, and the discovery could represent a major step forward in defeating the deadly disease.

NASA's iconic Kepler space telescope — which has discovered 70 percent of the 3,750 exoplanets known to date — is running so low on fuel that the agency has put it into a hibernation-like state, agency officials announced today (July 6).

In June 2017, physicists achieved 'liquid light' at room temperature for the first time ever, making this strange form of matter more accessible than ever.

For years, scientists at the Smithsonian Tropical Research Institute in Panama had whispered about the remote island where monkeys used stone tools. A botanist had witnessed the phenomenon during a long-ago survey — but, being more interested in flora than…
