SUNSET: 
Invite Ross 128 Over This Thanksgiving
With exoplanet Ross 128b in the news, we pay a visit to the star that sustains this potentially habitable exoplanet.
Puffed-Up Hot Jupiter Is Surprisingly Dark
Researchers have found that a football-shaped, ultra-hot gas giant that’s being devoured by its host star is also one of the least reflective exoplanets ever found.
An Atmosphere of Heavy Metals
Researchers have found strong evidence of titanium oxide in the atmosphere of a hot giant planet, adding new insights to the complex motions of these planets’ extreme atmospheres.
Looking Ahead: Space Exploration in 2017
An exciting year lies ahead for spaceflight involving astronomy and planetary science — by NASA and by other spacefaring nations.
Exoplanet Found in Triple Star System
Astronomers have retracted the discovery of a giant planet with an exceptionally wide orbit in a young system of three suns.
New Star and Exoplanet Names OK'd by IAU
Following a wildly popular contest, the International Astronomical Union has named 14 stars and 31 planets that orbit them.
The Planet That is No More

Exoplanet Portraits: A Tale of New Instruments
Exoplanet missions are shifting their goals from counting to characterizing, with multiple instruments coming online to directly image these alien worlds.
Three Exoplanet Molds: Metals Matter
Data from NASA's Kepler space telescope point to three distinct molds of exoplanets — rocky worlds, gas dwarfs, and ice/gas giants — distinguishable based on the abundances of heavy elements in their host star’s atmosphere.
Exoplanet Out for a Quick Spin
Astronomers have used a new technique to measure — for the first time — the spin of an extrasolar planet.
Planets’ Wacky Orbits Solved
By combining nearly 1,500 observations with sophisticated computer models, astronomers have shed light on a nearby planetary system, proving that the planets' bizarre orbits will actually remain stable for the next 100 million years.
