The gaseous atmospheres of giant planets may evaporate and accrete onto the dense surfaces of white dwarfs, providing astronomers a new way to detect hidden exoplanets.

An Exoplanet with Evolving Clouds of Salts
Clouds form and dissipate on a gas giant orbiting a Sun-like star.
Set to Music, Exoplanets Reveal Insights on Their Formation
Sonification hints at how some Kepler planets may have been configured in the late stages of their development.
Water Found in Small, Habitable Zone Planet’s Atmosphere
K2-18b is warm, has an atmosphere, and has water vapor. But it’s no Earth 2.0.
Nearest Star System May Have a Second Planet
The exoplanet candidate, tentatively named Proxima c, would be a frozen snowball.
Ultrahot Exoplanet Bleeds Heavy Metals into Space
The planet is also shaped like a football (the American kind).
Giant Planets and Brown Dwarfs Form in Different Ways
Once thought to be part of the same population, planets larger than Jupiter and “failed stars” likely grow via different mechanisms, the Gemini Planet Imager Exoplanet Survey has shown.
Chemical Patterns May Predict Stars That Host Giant Planets
Stars with giant planets tend to have a few key elements in abundance. A new algorithm used these patterns to predict hundreds of stars that will likely have exoplanets if we go looking for them.
Modeling the Climates of Worlds Beyond Earth
Scientists are applying climate models to distant planets to determine their habitability.
NASA Space Telescope Spots Its Third Planet
A planet 3 times as large as the Earth was detected by the Transiting Exoplanet Survey Satellite in a relatively leisurely orbit—the longest yet detected by this telescope—of 36 days.
