Enceladus' Water Geysers May Be 'Curtain Eruptions' According to New Study

The water vapor jets on Enceladus are now thought to mostly be more like diffuse “curtains” rather than separate plumes. Image Credit: NASA/JPL-Caltech/SSI/PSI

The water vapor geysers on Saturn’s moon Enceladus are one of the most fascinating phenomena in the Solar System; the jets spray far out into space in a dazzling display unseen […]

Astronomers Find First Evidence of Possible Volcanic Activity On a Super-Earth Exoplanet

Discovering new exoplanets has become rather routine in the last few years, but determining just what conditions exist on any of them is naturally more difficult, since […]

Worlds Beyond Our Own: Celebrating 25 Years of Hubble Science (Part 3)

A stunning image of a giant cluster of about 3,000 stars, called Westerlund 2, which lies approximately 20,000 light-years away from Earth. This image was officially selected by NASA to commemorate the 25th anniversary since the launch of the Hubble Space Telescope, on April 24, 1990.

Scientists have discovered a vast network of salty aquifers beneath the surface of Antarctica, thanks to an airborne imaging system used there for the first time. The finding may have interesting implications for the […]

New NASA NExSS Coalition to Lead Search for Life on Distant Exoplanets

The search for, and discovery of, exoplanets orbiting other stars has become a full-fledged endeavour in recent years, with thousands found so far and more being discovered practically every week. […]

Just Add Water: Scientists Explain Saturn's Powerful Thunderstorms

Thunderstorms are a powerful force of nature, but the ones we experience on Earth are dwarfed by the ones on the gas giant planet Saturn. They are huge and can be larger […]

Orbiting Rainbows: Using 'Glitter Clouds' to Search For and Image Exoplanets

The search for exoplanets may one day get a lot more glittery. It sounds a bit like science fiction, but a new NASA proposal called Orbiting Rainbows would use glitter-like materials to help image some of those far-away worlds, which could enable high-resolution imaging at a fraction of the cost.

[…]

'Old Earths': The Search for Ancient and Habitable (But Dying) Exoplanets

Researchers at Cornell University are taking a new approach to the search for alien life: looking for habitable planets older than Earth, […]

Spitzer Space Telescope Discovers Distant Exoplanet Across the Milky Way

Utilising NASA’s Spitzer Space Telescope, astronomers have discovered a distant exoplanet located 13,000 light-years away, through gravitational microlensing. The red cone in the map above our Solar System, depicts the extend in the galaxy of the thousands of known exoplanets that have been discovered by NASA’s Kepler space telescope, while the red circle represents […]

Astronomers Detect Complex Organics Around Nearby Young Star; Produce Them in Simulated Conditions in the Lab

Artist’s impression of the protoplanetary disk surrounding the young star MWC 480. Astronomers using the Atacama Large Millimeter/submillimeter Array, or ALMA, have detected the complex organic molecule methyl cyanide in the outer reaches of the star’s protoplanetary disk, where comets are believed to form. This discovery suggests that complex organic chemistry and potentially the […]
