To Extrapolate Human Perception: Imaging the Solar System in 3-D With Hubble & Webb

A breathtaking Hubble image of Saturn in ultraviolet light, showing the planet’s southern hemisphere and the southern face of its rings. A new study has proposed utilising the observing capabilities of Hubble together with the upcoming James Webb Space Telescope, for capturing stereoscopic 3-D images of planets in the Solar System.

For a long time now, there have been theories and rumors regarding the possible existence of another planet in our Solar System, […]

Mystery Deepens: New Study Shows Comets Don't Explain Odd Dimming of Kepler's 'Weird Star'

The mystery surrounding KIC 8462852 may not involve comets after all, but it is still an enigma for astronomers. Image Credit: NASA/JPL-Caltech

As has been reported previously on AmericaSpace, and elsewhere, there is something weird going on around a star which is a little over 1,400 light-years away. Astronomers are still baffled as […]

Astronomers Identify New Substances on Europa of Possible Underground Origin

An image mosaic of Europa taken from NASA’s Galileo spacecraft, showing the moon’s famous “chaos terrain” of linear cracks and ridges that crisscross almost its entire surface. A new research by a team of U.S. astronomers has identified a previously unseen set of minerals along Europa’s chaos terrain, which are thought to have […]

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

Astronomers have begun a follow-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 […]

If there is one mantra that drives the development of space mission projects, it’s ‘test, test, test’. Before every successful manned or robotic mission has ever flown to space countless man-hours were devoted for extensive and rigorous testing on […]

NASA Seeks Public's Help Designing Ways for Astronauts to Live off the Land on Mars

As part of its research and development efforts on in-situ resource utilisation, NASA has recently announced the In-Situ Materials Challenge which seeks proposals from the public on converting in-situ extraterrestrial materials into structural elements that would be useful for human deep space missions.

In the much-advertised Hollywood sci-fi blockbuster movie […]

New Study Suggests Abundance of Nitrogen on Pluto May Be Due to Cryovolcanism

A spectacular image of Pluto’s atmosphere backlit by the Sun, taken during New Horizons’ closest approach to Pluto on July 14. The bright halo of Pluto’s atmosphere is caused by the scattering of sunlight from nitrogen, a compound that dominates the planet’s atmosphere. A new study suggests that the source of all this […]
