Moving across a background of stars, the six red dots in this composite picture indicate the location of six sequential detections of the first near-Earth object discovered by NEOWISE after the spacecraft came out of hibernation in 2013: the asteroid 2013 YP139. The inset shows a zoomed-in view of one of the detections.Observed by NASA’s WISE mission, this image shows the entire sky seen in infrared light.
The infrared telescope is going out of commission having exceeded scientific objectives for not one, but two missions, beginning as Comet NEOWISE was discovered by its namesake mission on March 27, 2020, and became a dazzling celestial object visible in the Northern Hemisphere for several weeks that year. It was one of 25 comets discovered by the mission.Invisible to the naked eye, infrared wavelengths are emitted by warm objects. To keep the heat generated by WISE itself from interfering with its infrared observations, the spacecraft relied on cryogenic coolant.

Team creates custom-made molecules designed to be invisible while absorbing near-infrared lightGetting a molecule to do what you want it to do is not always easy. An organic molecule will absorb only certain wavelengths of light based on its arrangement of electrons, which can be difficult to fine tune. Even so, the ability to make substances that respond to only specific ranges of the spectrum could lead to important new applications.
