Sometimes lost in the discussion of exoplanets and habitability is where the potential building blocks of life might come from and how they got there. Yes, hydrogen and water and methane and carbon and nitrogen have been found in abundance around the cosmos, but how about the larger and more esoteric compounds needed for life …
A Solar System Found Crowded With Seven Earth-Sized Exoplanets
Seven planets orbiting one star. All of them roughly the size of Earth. A record three in what is considered the habitable zone, the distance from the host star where liquid water could exist on the surface. The system a mere 40 light-years away. The latest impressive additions to the world of exoplanets orbit the …

Found: Our Nearest Exoplanet Neighbor
No exoplanet can possibly be closer to us than the one just detected around our nearest stellar neighbor, Proxima Centauri. The long-sought and long-imagined planet is larger than Earth, but small enough to be rocky as opposed to a gas or ice giant. Making things even more exciting, the planet was detected inside the habitable …
Three Star Ballet, With Exoplanet
It hardly seems possible, but researchers have detected a planet in apparently stable orbit within a three star system -- a configuration now known as a trinary. The ubiquity of binary stars has been understood for some time, and the presence of exoplanets orbiting around and within them is no longer a surprise. But this …

The Pale Red Dot Campaign
Astronomers have been trying for decades to find a planet orbiting Proxima Centauri, the star closest to our sun and so a natural and tempting target. Claims of an exoplanet discovery have been made before, but so far none have held up. Now, in a novel and very public way, a group of European astronomers …
