... Aperture is the generic term used for any targetable area in an SI; a small slit, an occulting finger, different points on a CCD, a virtual aperture that encompasses a number of chips (e.g. WFALL), anything that can be specified in the APERTURE field of the proposal file, and a few more that can't. The scales, orientations, locations in the HST FOV, and a number of other properties of these targetable areas are calibrated and updated periodically. ...

At Arecibo we have a variety of optical instruments that we use to study terrestrial airglow emissions. ... As a complement to the airglow instrumentation we also maintain a set of optical instruments, called lidars, used for "active" remote sensing of the atmosphere. That is, we generate our own source signal using lasers and measure the characteristics of the light scattered back from the atmosphere. ... An operations manual for the Optical Laboratories is currently under major revision. ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...
