Researchers discuss why alien life in our solar system looks likelier than ever.
Ewine van Dishoeck, the 2018 Kavli Prize laureate, discusses her personal and professional journey into the field of astrochemistry.
Jacqueline Hewitt discusses how NASA's TESS exoplanet mission has already changed the institute she directs and will bring about further evolution in the years to come.
The just-launched Transiting Exoplanet Survey Satellite (TESS) could soon provide the breakthrough identification of dozens of potentially habitable exoplanets right in our cosmic backyard.
A newfound star in a nearby galaxy appears to have cheated death by blowing up at least twice as a supernova. It could be a throwback to the first stars that ever formed.
The prevailing view of the universe has just passed a rigorous new test, but the mysteries of dark matter and dark energy remain frustratingly unsolved.
Earth's pale blue color contains some unique signatures of life, a new study shows. This finding could help scientists identify life on distant planets.
New telescopes and techniques are helping scientists probe exoplanets in their earliest stages of development.
The hunt for gravitational waves took decades — what's it like to see the target of your life's work finally revealed?
Learn the latest about Pluto in a live Google Hangout with NASA New Horizons co-lead Richard Benzel, team member Cathy Olkin, and Pluto expert Michael Brown.
Huge "super-Jupiter" exoplanets could sport water-rich, potentially habitable moons up to a few times more massive than Mars, a new study suggests.
A massive new telescope under construction in Chile, the LSST, will be one of the largest eyes on the sky — and it's getting scientists excited about what they might find.
Although DNA and RNA would not function in environments like that of Saturn's moon Titan, ethers could fulfill this key role.
A new study sheds light on how exoplanets in tightly-packed solar systems interact with each other gravitationally by affecting one another's climates and their abilities to support alien life.
Our young sun may have routinely blasted Earth with gobs of energy more powerful than any similar bombardments recorded in human history.
