New Uranus-Like 'Ice Giant' Exoplanet Discovered

Many different kinds of exoplanets have been found by astronomers, from giant “hot Jupiters” and “super Earths” to smaller rocky worlds like Earth or Mars. Now, another type has been discovered, an “ice giant” similar to Uranus or Neptune in our [...]

Astronomers Create Most Detailed Weather Map Yet of an Exoplanet

Being able to find exoplanets orbiting distant stars is a major accomplishment in itself, and fine-tuning the data [...]

Clear Skies Above: Astronomers Detect Water Vapor on Cloud-Free Atmosphere of a Hot-Neptune

Sunny and hot all year-round, with no clouds on the horizon … That’s not a weather forecast only for the Maldive [...]

Astronomers Witness Asteroid Smash-Up Around Sun-Like Star

Solar systems, including ours, are thought to begin as massive clouds of dust and gas surrounding young stars; over billions of years, planets form from repeated impacts of [...]

ESA's 'Discovery Machine' Gets Ready for Science: Gaia Concludes Commissioning Phase, Begins Primary Five-Year Mission

Artist’s concept of the Gaia. Having recently completed a rigorous test and commissioning phase, the space observatory began its five-year primary science mission of mapping and cataloguing approximately 1 billion stars in the Milky Way galaxy. Image Credit: ESA–D. Ducros, 2013

Following the successful conclusion of a very demanding and extensive six-month commissioning period, [...]

No Water, Please: The Case of the Surprisingly Dry 'Hot Jupiters'

This is an artistic illustration of the gas giant planet HD 209458b in the constellation Pegasus. The planet was recently studied by astronomers alongside two other similar extrasolar worlds, for their abundance in water. To the surprise of astronomers, they have found much less water vapor in the planets’ atmospheres than standard planet-formation models [...]

Astronomers Discover First Ice Giant Exoplanet Candidate in Long-Period Orbit

This artist’s concept shows Kepler-421b, a Uranus-sized transiting exoplanet with the longest known year, circling its star once every 704 days. Kepler-421b orbits an orange, K-type star that is cooler and dimmer than our Sun and is located about 1,000 light-years from Earth in the constellation Lyra.

As the number of exoplanets discovered continues to grow exponentially, the number of potentially habitable worlds out there continues to increase as well. Astronomers have now reported finding another one of the nearest known of these kinds of planets so far, Gliese [...]

From a Galaxy Far, Far Away: Astronomers Discover Ancient Super-Earths in Our Galactic Neighborhood

Artistic representation of the recently discovered, potentially habitable world Kapteyn b, with the globular cluster Omega Centauri in the background. It is believed that the Omega Centauri is the remaining core of a dwarf galaxy that merged with our own galaxy billions of years ago, bringing Kapteyn’s star along.
