Small icy moons in the outer reaches of our solar system may hide boiling oceans underneath their surfaces, a new study finds. Previous research found that some of the icy
This illustration shows a red dwarf star orbited by a hypothetical exoplanet. Red dwarfs tend to be magnetically active, displaying gigantic arcing prominences and a wealth of dark sunspots. Red
One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic
A decision tree strategy for characterizing Earth-like exoplanets (Young et al. 2024). This tree indicates which gasses to observe, and in which order, to detect the biosignatures of Earth through
SAN FRANCISCO – GHGSat announced plans Nov. 7 to send two additional satellites into its greenhouse-gas-monitoring constellation. Ahead of the 30th Conference of the Parties to the United Nations Framework
ORLANDO, Fla. — NASA is at a “crossroads” in deciding how to handle logistics for the lunar Gateway as it considers alternative approaches. NASA selected SpaceX in 2020 for the
NASA unveiled close-up pictures on Wednesday of the interstellar comet that’s making a quick one-and-done tour of the solar system.
The technologies pushing the boundaries of the space economy sound as if they came from a science fiction novel: reusable rockets, satellite assembly lines, lunar landers and octocopters. On Nov.
Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue
