Within the next five years, global warming is set to breach the 1.5°C threshold at the heart of the 2015 Paris Agreement. This will have dire consequences, from rapidly melting ice sheets to ghostly white coral reefs.
Choosing an orbit for a satellite always comes with trade-offs. Very low Earth orbit (VLEO), between 100–450 km (62–280 miles), has distinct advantages. Remote-sensing cameras can take better pictures, communications and ...
Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a chemical journey that could eventually deliver ...
The James Webb Space Telescope (JWST) has opened many wonders of the cosmos to scientists since it began science operations a few years ago. But one thing it hasn't done is find an "exomoon." These still-theoretical moons ...
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitational waves (i.e., ripples in spacetime) that ...
An eye surgeon with a passion for space since childhood predicts that as astronauts start to make journeys to the moon and Mars in the near future, eye surgery in space will eventually become a necessity.
We've found more than 5,500 exoplanets so far. Dozens of them are in the habitable zones of their parent stars, where, at least in theory, they could host an ocean. But we've never definitively found a liquid ocean on another ...
Scientists have discovered that there is ice deep inside planets like Neptune and Uranus and want to find out what form it takes and how it behaves. They cannot dig for it and transport it all the way back to Earth, so they ...
NASA is bringing artificial intelligence to the study of the moon, helping researchers transform how they analyze its surface. In an ongoing collaboration with IBM Research and several academic institutions, NASA has launched ...
The sun is capable of great things. In massive eruptions, it repeatedly hurls particles and radiation into space. This solar bombardment can be dangerous for technical infrastructure on Earth: For example, satellites and ...
