2022 WJ1 was a tiny asteroid on a collision course with Earth. But astronomers saw it coming, and NASA’s Scout impact hazard assessment system calculated where it would hit. In the early hours of Saturday, Nov. 19, the skies over southern Ontario, Canada, lit up as a tiny asteroid harmlessly streaked across the sky …

An asteroid the size of a delivery truck will pass Earth in one of the closest such encounters ever recorded – coming within a tenth of the distance of most communication satellites’ orbit. NASA said the newly discovered asteroid would pass 2,200 miles (3,600km) above the southern tip of South America at 7.27pm US eastern time …

A case study involving Europe’s largest coal-fired power plant shows space-based observations can be used to track carbon dioxide emissions – and reductions – at the source. A duo of Earth-observing missions has enabled researchers to detect and track carbon dioxide (CO2) emission changes from a single facility, using the world’s fifth-largest coal-fired power …

With help from a cryocooler, the Mid-Infrared Instrument has dropped down to just a few degrees above the lowest temperature matter can reach and is ready for calibration. NASA’s James Webb Space Telescope will see the first galaxies to form after the big bang, but to do that its instruments first need to get …

Based partly on data from generations of NASA missions, including NASA’s Voyager and Cassini, the work could help scientists determine how to predict weather on Jupiter. Scientists have completed the longest-ever study tracking temperatures in Jupiter’s upper troposphere, the layer of the atmosphere where the giant planet’s weather occurs and where its signature colorful …
