Actually, the group of bananas commonly referred to as a bunch at the store is actually a hand, or less commonly tier.
PSR B1509-58 - X-rays from Chandra are gold; Infrared from WISE in red, green and blue/max. A pulsar (from pulse and -ar as in quasar) is a highly magnetized, rotating neutron star or white dwarf, that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much like the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission.
LIDAR (Light Detection and Ranging) is a remote sensing technology that collects 3-dimensional point clouds of the Earthâs surface. This technology is being used for a wide range of applications including high-resolution topographic mapping and 3-dimensional surface modeling as well as infrastructure and biomass studies. Airborne LIDAR instrumentation uses a laser scanner with up to 400,000 pulses of light per second.
