Astronomers have discovered two new alien worlds a bit larger than Earth circling a nearby star.
Hubble’s scientific bounty has benefited a wide range of astronomical and astrophysical fields, including the study of planets, moons and small icy bodies in the outer solar system and the cosmological history of the universe. Here’s a look at a few of Hubble’s greatest hits.
Astronomers have detected an exoplanet's visible-light spectrum directly for the first time ever, a milestone that could help bring many other alien worlds into clearer focus down the road.
Does it exist or not? Astronomers are claiming that the potentially habitable exoplanet is just noisy data, while others say it's too early to discount the existence of Gliese 581d.
For only the second time, an exoplanet living with an expansive family of four stars has been revealed.
A new study has taken a look at the gas giant from a whole different perspective -- as an alien, living far beyond the solar system, would see it.
By watching how an exoplanet orbiting the star Beta Pictoris interacts with circumstellar dust, astronomers are beginning to understand how to look for the dusty fingerprints of hidden alien worlds. Continue reading →
New research suggests that the frozen cores of 'mini-Neptunes' could be transformed into habitable worlds with a little help from their red dwarf hosts.
