NASA's DART spacecraft slammed into asteroid Dimorphos at 22,530 km/h in 2022 and shifted its orbit by 33 minutes — proving planetary defense actually works.
A 13.8-billion-year timeline of the universe: from inflation and the first atoms to JWST's cosmic dawn images, galaxy formation, and the origins of life on Earth.
Astronomers have confirmed 5,700+ exoplanets since 1992 — how transit, radial velocity, direct imaging, microlensing, and astrometry each find worlds around distant stars.
K2-18b sits 124 light-years away and JWST found possible dimethyl sulfide — a molecule made mostly by life on Earth. Here's the biosignature debate in full.
How JWST actually works: 18 gold-coated mirrors, a tennis-court sunshield, 344 single points of failure, and the infrared tricks that revealed the early universe.
James Webb Space Telescope, बिना किसी अतिशयोक्ति के, अंतरिक्ष में तैनात किया गया अब तक का सबसे जटिल वैज्ञानिक उपकरण है। इसे विकसित करने में 25 वर्ष लगे, लागत लग…
