We still don’t know if there is life elsewhere in the universe, but scientists are working on techniques to better understand how it may have originated anyway, in the event that such alien biology is […]

The Gemini Planet Imager, a new telescopic instrument designed to find, image, and study faint, young planets orbiting bright stars, has discovered its first exoplanet: a young Jupiter-like planet called 51 Eridani b which orbits […]

Kepler Update: Earth's 'Bigger and Older Cousin' Discovered Orbiting Distant Star

One of the primary goals in the search for exoplanets is to, hopefully, find an Earth analog or “Earth twin,” an alien world similar to our own. That search is still […]

Astronomers Determine Progenitors of Supernova Explosions More Varied Than Thought

Type Ia supernova explosions can be considered as some of the Universe’s most spectacular and inviting attractions, signifying the death of very massive stars. With peak luminosities […]

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.

One defining scientific revolution of […]

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 […]

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 […]

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

NASA’s NExSS collaboration will bring together scientists from diverse backgrounds to help search for evidence of life in other Solar Systems. Image Credit: NASA

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.


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