Published in the peer-reviewed The Astrophysical Journal, the research focuses on tidally locked planets, worlds that always ...

An international team of scientists, including researchers at Penn State, dubbed the exoplanet, named GJ 251 c, a “super-Earth” as data suggest it has a rocky composition similar to Earth and is ...

The discovery of a possible "super-Earth" less than 20 light-years from our own planet is offering scientists new hope in the hunt for other worlds that could harbor life, according to an ...

At the beginning of the exoplanet age, the goals were fairly simple. The first was to find as many of them as possible to ...

Could a recently discovered "super-Earth" have the potential temperature and conditions to sustain life? The new exoplanet is situated "fairly close to us" -- only 137 light-years away -- and orbits ...

A newly discovered planet sits in the habitable zone of its star, where temperatures are right for liquid water if the atmosphere is appropriate. Based on the available data, GJ 251c is thought most ...

Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that ...

WASHINGTON — An Earth-sized planet in its star's habitable zone has been discovered in data from NASA’s Kepler space telescope. NASA says the newly found exoplanet is the closest to Earth in size and ...

Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known ...

The Penn State-led Habitable Zone Planet Finder (HPF) provides the highest precision measurements to date of infrared signals from nearby stars. Pictured: The HPF instrument during installation in its ...
