Hints of Life on Exoplanet K2-18b Recede Even Further
New observations fail to confirm signs of life in the atmosphere of the distant planet K2-18b. They also raise questions about what it will take to detect biology light-years away.
New Studies Dismiss Signs of Life on Distant Planet
In April, astronomers said they had detected a possible signature of life on the exoplanet K2-18b. Now, three independent analyses discount the evidence.
Astronomers Detect a Signature of Life on a Distant Planet
Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even habitable.
A Parade of Planets Is Marching Through the Night Sky
With Mercury joining the show, all seven of Earth’s celestial neighbors will be present at dusk this week.
Barnard’s Star Finally Has a Planet, and Possibly More
For a century, exoplanet hunters have “discovered” planets around a nearby star, only to retract the claims. But the latest find is for real.
NASA Sends a Missy Elliott Song to Space
NASA sent the song “The Rain (Supa Dupa Fly)” from a radio dish in California last week. It took 14 minutes to travel the 158 million miles.
As Stellar Observations Improve, Earth’s History and Future Get Fuzzier
Astronomers have gotten better at tracking the motions of stars just beyond the solar system. But that’s made it harder to predict Earth’s future and reconstruct its past.
