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.

Saturn’s moon Titan is one of the murkiest places in the Solar System; its thick smog-like hydrocarbon haze in the upper atmosphere shrouds the entire moon, much like Venus’ perpetual cloud [...]

Kepler Phase 2: Planet-Hunting Space Telescope's New Mission Proposal Approved

There is some good news for planet-hunters this week: The proposed K2 mission extension for the Kepler Space Telescope has been been approved by NASA. The approval, based on a recommendation from [...]

Searching for Our Birthplace in the Galaxy: Astronomers Discover Potential Solar 'Sibling'

A visible image of the star HD 162826 (at right) in the constellation of Hercules, taken from the Digitized Sky Survey (DSS). A new study has identified the star as a being a solar sibling, thought to have been formed inside the same interstellar gas cloud that also gave birth to the Sun. Image [...]

Between the Planet and the Star: A New Ultra-Cold, Sub-Stellar Object Discovered Close to Sun

Contrary to the human need for organising objects in well-defined and distinct categories, our Solar System seems to be replete with celestial objects that defy our tidy definitions [...]

Studying the Light of Alien Atmospheres With NESSI

A new multi-object, near-infrared spectrograph, installed on the Magdalena Ridge Observatory’s 2.4-m Telescope, will study the atmospheres of extrasolar planets located relatively close to Earth, allowing astronomers to probe their chemical composition. Image Credit: MRO

Exoplanetary astronomy has been one of the most productive scientific endeavors in recent years, with new discoveries of planets [...]

Big Discovery: First Earth-Sized Exoplanet in Habitable Zone of Another Star

Today was another big day for those interested in space exploration and in the search for other Earth-like, alien worlds in particular: The first Earth-sized exoplanet orbiting another star in the habitable zone has been discovered, it was [...]

First Direct Imaging of Exoplanet in Visible Light Obtained by Ground-Based Telescope

Image of the exoplanet Beta Pictoris b made with the Magellan Adaptive Optics (MagAO) VisAO camera. This image was made using a CCD camera, which is essentially the same technology as a cell phone camera. The planet is nearly 100,000 times fainter than its star and orbits its star at roughly the same distance [...]
