Editor’s Note, Jan. 11, 2026: NASA’s Pandora and the NASA-sponsored BlackCAT and SPARCS missions lifted off at 8:44 a.m. EST (5:44 a.m. PST) Sunday, Jan. 11. A new NASA spacecraft called Pandora is awaiting launch ahead of its journey to study the atmospheres of exoplanets, or worlds beyond our solar system, and their stars. Along […]

Lee esta nota de prensa en español aqui. A team of researchers has confirmed stars ring loud and clear in a “key” that will harmonize well with the science goals and capabilities of NASA’s upcoming Nancy Grace Roman Space Telescope. Stars’ turbulent natures produce waves that cause fluctuations in their overall brightness. By studying these […]

The milestone highlights the accelerating rate of discoveries, just over three decades since the first exoplanets were found. The official number of exoplanets — planets outside our solar system — tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no […]

Kepler / K2
The Kepler mission enabled the discovery of thousands of exoplanets, revealing a deep truth about our place in the cosmos: there are more planets than stars in the Milky Way galaxy. The road to this fundamental change in our understanding of the universe, however, required almost 20 years of persistence before the mission became a […]

A new study could explain the ‘missing’ exoplanets between super-Earths and sub-Neptunes. Some exoplanets seem to be losing their atmospheres and shrinking. In a new study using NASA’s retired Kepler Space Telescope, astronomers find evidence of a possible cause: The cores of these planets are pushing away their atmospheres from the inside out.

A system of seven sweltering planets has been revealed by continued study of data from NASA’s retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system. Also unlike any of our immediate neighbors, all seven planets in this system, named […]

NASA’s Nancy Grace Roman Space Telescope will provide one of the deepest-ever views into the heart of our Milky Way galaxy. The mission will monitor hundreds of millions of stars in search of tell-tale flickers that betray the presence of planets, distant stars, small icy objects that haunt the outskirts of our solar system, isolated […]
