The detection of 30 comets in another solar system – exocomets – could shed light on the formation of our own system of planets.
Discovery Alert: 30 'Exocomets' Orbit a Familiar Star
An international team of astronomers confirms 60 new exoplanets, or planets orbiting other stars; a separate study finds tentative evidence of an “exomoon.”
Discovery Alert: A Flood of New Planets, Plus Hint of an ‘Exomoon'
The count of confirmed exoplanets just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes.
Cosmic Milestone: NASA Confirms 5,000 Exoplanets
Scientists will be able to measure a specific kind of space dust in nearby planetary systems’ habitable zones. Finding out how much of this material these systems contain would help astronomers learn more about how rocky planets form and guide the search for habitable worlds.
Studying Dust to Find New Worlds
NASA announced the discovery of seven Earth-size worlds orbiting the TRAPPIST-1 star five years ago. We've learned more in the years since, and we'll get an unprecedented look with the James Webb Space Telescope.
Day of Discovery: 7 Earth-Size Planets
The atmosphere of a "super Neptune" some 150 light-years distant contains water vapor, a new study shows.

NASA's James Webb Space Telescope is in space! How long will it take to fully deploy and get into configuration?
What's Next for the Webb Telescope?
A new catalog of planets around other stars includes hundreds of new discoveries, and could offer insight into planet formation and variety.
Discovery Alert: 172 Possible Planets? A New Roadmap to Distant Worlds
A new machine-learning method yields 301 new exoplanet discoveries from the retired Kepler Space Telescope.
New Deep Learning Method Adds 301 Planets to Kepler's Total Count
NASA scientists create a scale for evaluating possible signs of life beyond Earth.
Are We Alone in the Universe? NASA Calls for New Framework
A new study shows how the chemicals in an exoplanet’s atmosphere can, in some cases, reveal whether or not the temperature on its surface is too hot for liquid water.
How to Find Hidden Oceans on Mysterious Worlds? Chemistry
Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time. This intriguing result opens a new window to search for exoplanets at greater distances than ever before.
