 3M TMA Among the instruments aboard Lazuli is a camera with 23 CMOS detectors, each of which will be outfitted with fixed filters (both broadband and narrowband) covering wavelengths spanning the visible to near-infrared range (400 to 1,700 nanometers). The observatory will also have an integral field spectrograph, which takes spectra across an entire image as well as a coronagraph, a mask that blocks bright sources to enable detection of fainter ones. Supriya Chakrabarti (University of Massachusetts, Lowell), whose team has contributed to Lazuli, is excited to use that capability to directly image exoplanets around nearby stars. Lazuli is not a Hubble replacement. But it does offer competitive advantages, drawing on technology that is 20 years more advanced than what is onboard the iconic observatory. The announcement of the ambitious Schmidt Observatory System, one of the biggest releases to come out of last week’s American Astronomical Society meeting in Phoenix, Arizona, comes...
