New Study Reassesses Habitability of Exoplanets Around Multiple Star Systems

An artist’s concept of Kepler-47, which was the first-ever planetary system to be discovered orbiting a binary star. A new research that was based on data taken with NASA’s Hubble Space Telescope provides stringest limits to the potential habitablity of exoplanets in several such systems.

Cloudy With a Chance of Sunshine: Astronomers Study Weather on Distant Exoplanets

An artist’s rendering of the possible weather and atmospheric circulation patterns on hot Jupiters. A new research by a team of astronomers that was based on data taken with NASA’s Kepler space telescope, studied the phase variations that occur as different portions of these planets are illuminated by their host stars as seen from […]

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. […]

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.

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 […]

Two Earth-Sized Exoplanets May Exist in Closest Star System, Hubble Observations Reveal

The closest star system to our own Sun may have two Earth-sized exoplanets orbiting it, a new study has shown based on observations by the […]

Jupiter Might Be Responsible for Our Unusual Solar System, Study Suggests

A montage of Jupiter and its volcanic moon Io, as seen by NASA’s New Horizons spacecraft on its way to Pluto. The results of a new study indicate that the massive gas giant fundamentally altered the evolution of the early Solar System, by destroying any “Super-Earth”-type planets that may have formed, while opening the […]

Under the Light of a Quadruple Sun: Astronomers Discover Additional Stellar Companions in Nearby Exoplanetary Systems

Artist’s conception of the quadruple star system 30 Arietis. The primary star, called 30 Arietis B, has a companion (the small “red dwarf” star shown at upper left). This pair of stars is itself locked in a long-distance orbit with another pair of stars (upper right), known as 30 Arietis A. A team of […]

Astronomers Discover Ancient Terrestrial Exoplanets Around Neighboring Star

Artist’s concept of the recently discovered, tightly packed, and ancient exoplanetary system named Kepler-444. Astroseismic studies of the star’s oscillations, allowed astronomers to determine that it is the oldest planetary system discovered to date, with an age of approximately 11 billion years.
