NASA: Possible Reason Some Exoplanets Are Shrinking
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,…

Decarbonizing Light-Duty Transportation in the US: Strategies to Achieve Goal
One of the goals outlined by the Biden administration’s National Climate Task Force in 2021 was to reduce U.S. greenhouse gas emissions to 50%-52% below 2005 levels by 2030. Transportation,…
US regulator greenlights Starship’s next launch on Friday
Starship, which stands 394 feet (120 meters) tall, produces 16.7 million pounds (74.3 Meganewtons) of thrust, more than double that of the Saturn V rockets used to send Apollo astronauts…
The universe is expanding faster than theory predicts—physicists are trying to explain the mismatch
The James Webb Space Telescope’s deep field image shows a universe full of sparkling galaxies. Credit: NASA/STScI Astronomers have known for decades that the universe is expanding. When they use…

NASA’s Lucy Surprises Again, Observes 1st-ever Contact Binary Orbiting Asteroid
There is more to the “marvelous” asteroid Dinkinesh and its newly discovered satellite than first meets the eye, as NASA’s Lucy mission revealed. As NASA’s Lucy spacecraft continued to return data…
