Water Vapor is Detected on a Tiny Exoplanet by Hubble!
Scientists using the Hubble Space Telescope have discovered water vapor in the atmosphere of GJ 9827d, the smallest exoplanet observed to date with such a finding. Measuring only about twice the size of Earth, this planet hints at the possibility of water-rich atmospheres on other worlds in our galaxy.
Exploring Ancient Stars as Potential Havens for Life
In a cosmic twist, recent observations challenge the long-held belief that stars endure an eternal magnetic slowdown. Scientists, armed with new insights, reveal that stars, especially those experiencing midlife crises, might be key locations for discovering alien neighbors. The findings mark a paradigm shift in our understanding of celestial dynamics.
Shrinking Exoplanets: NASA Data Offer a Possible Clue
A recent study may provide insights into the apparent absence of exoplanets between super-Earths and sub-Neptunes. Observations from NASA's retired Kepler Space Telescope suggest a potential explanation: the cores of these planets are internally displacing their atmospheres, leading to shrinkage. The findings are detailed in The Astronomical Journal.
