NASA’s DART spacecraft hits target asteroid in first planetary defense test

September 26 (Reuters) – NASA’s DART spacecraft successfully slammed into a distant asteroid at hypersonic speed on Monday in the world’s first test of a planetary defense system, designed to prevent a possible apocalyptic meteorite collision with the Earth. Humanity’s first attempt to alter the motion of an asteroid or any celestial body took place …

NASA is preparing to deflect the asteroid, in a key test of planetary defense

A man sits at his workstation within the Mission Operations Center for the Double Asteroid Redirection Test (DART) spacecraft, which is rapidly approaching its target. I bet the dinosaurs would have liked to think of that. On Monday, NASA will attempt a feat humanity has never accomplished before: deliberately ramming a spacecraft into an asteroid …

NASA's Webb Space Telescope is so good we might need improved planetary models

NASA’s Webb Space Telescope is so good we might need improved planetary models

It has become overwhelmingly clear over the past few months that NASA’s James Webb Space Telescope is doing exactly what it set out to do. As its creators had hoped, the multibillion-dollar machine ‘unfolds the universe’ perfectly, revealing cosmic light we can’t see with our own eyes – and its excellent results have even astronomers …

MIT warns astronomers risk misinterpreting planetary signals in Webb Space Telescope data

MIT warns astronomers risk misinterpreting planetary signals in Webb Space Telescope data

Astronomers risk misinterpreting planetary signals in data from the James Webb Space Telescope if models for interpreting the data don’t improve, an MIT study finds. In this concept image, the James Webb Telescope captures light around a newly discovered planet (left). However, when scientists analyze this data, the limitations of opacity models could produce planetary …
