Astronomers using NASA's James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in the Milky Way galaxy.
What does it take to catch up with a small, tumbling rock hundreds of thousands of kilometers from Earth? For China's Tianwen-2 mission, the answer was a 400-day chase covering roughly 1 billion kilometers (621 million miles) ...
Scientists have painted the most detailed portrait yet of the planetary system orbiting Barnard's Star—the sun's closest neighbor after Alpha Centauri, just under six light-years from Earth.
A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological ...
NASA's Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the "Broom Point member" ...
A new study by Caroline Ganglo and Stefan Karlowsky from the Leibniz Institute for Horticultural Sciences (IGZ) investigated whether human excreta-derived fertilizers are suitable for replacing mineral fertilizer in kohlrabi ...
Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet's ice. These features emit a glow when sunlight bounces off dust and water droplets. ...
There is a clear need to shift toward healthier and more sustainable food systems. According to the 2025 EAT-Lancet Commission Report, global adoption of a flexitarian Planetary Health Diet could prevent around 15 million ...
A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the ...
When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those concerns are real. But while working on our recent research, I found myself asking a different question: ...
