The search for exoplanets – planets orbiting other stars – has been one of the most exciting developments in astronomy and space science in recent years. The first couple exoplanets were found in 1992, and now over 3,400 have been confirmed, […]

Pluto, a tiny frigid world in the distant outskirts of the Solar System, has been full of surprises, as first revealed by the New Horizons spacecraft back […]

Artist’s conception of what Proxima b might look like. It is just slightly more massive than Earth and orbits in its star’s habitable zone. Temperatures might allow liquid water to exist on its surface. A potentially habitable world, it is also now the closest known exoplanet. Image Credit: ESO/M. Kornmesser
Astronomers today announced one […]

Over the past couple decades, astronomers have been discovering a seemingly endless variety of exoplanets orbiting other stars. Some are rather similar to planets in our own Solar System, while others are more like […]

For several years now the Kepler Space Telescope, as well as other telescopes, has been discovering an increasing number of exoplanets, with over 2,000 such confirmed worlds found so far (and nearly 5,000 candidates). Today, […]

Exoplanets are now being discovered by the thousands, but most are so far away that determining anything specific about their composition or atmosphere is currently very difficult. But technology keeps advancing, and scientists are now starting to be […]

Astronomers have discovered another Earth-sized exoplanet that is the closest one to our own Solar System found so far, but it might not be a nice […]

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 […]
By Leonidas Papadopoulos 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 […]
