Preparing For Launch: An Update on JWST
Move over, Hubble! NASA's currently in the middle of building Hubble's successor as we speak. The James Webb Space Telescope (JWTS) will help astronomers understand the history of the universe using infrared technology and a mirror coated in 24-karat gold! To discover how these function, read on, and prepare to launch!
Heat Sensitive Security Systems
While much of the technology in movies seems like science fiction, a good number of the interesting devices we see in films actually exist and, in a simpler form, are used every day. For example, the movie Mission: Impossible featured a heat-sensitive security system designed to sense the slightest changes in temperature. In a simplified form, the same technology is already at work in passive infrared systems and more sophisticated heat-sensitive alarms.
Dark Asteroids Discovered, Possible Threat to Earth
Dark asteroids near Earth, hard to spot but potential threats. WISE infrared telescope helps detect them. What's the risk of asteroid impact?
