The OVRO 40 meter Telescope, part of the Owens Valley Radio Observatory located near Big Pine, California, USA. The telescope is used to conduct interferometric observations along with the other telescopes in the observatory, as a Very Long Baseline Interferometry (VLBI) station and as a single dish instrument. Its main focus today is on the monitoring of blazars

Radio telescope antenna, part of the Very Long Baseline Array (VLBA). The Very Long Baseline Array (VLBA) is a system of ten radio telescopes which are operated remotely from their Array Operations Center located in Socorro, New Mexico, as a part of the National Radio Astronomy Observatory (NRAO). These ten radio antennas work together as an array that forms the longest system in the world that uses very long baseline interferometry, Big Pine, California

Punta Norte, the northern point of Guadalupe Island, viewed from the north.  Punta Desfiladero (Blunt Point) and Roca Elefante are just visible at far right, and Roca Piloto (Pilot Rock) is see to the left of the island against the distant sweep of the cliffs that comprise the northeastern bight of the island, actually the rim of an enormous caldera, Guadalupe Island (Isla Guadalupe)

Great white shark, research identification photograph.  A great white shark is countershaded, with a dark gray dorsal color and light gray to white underside, making it more difficult for the shark's prey to see it as approaches from above or below in the water column. The particular undulations of the countershading line along its side, where gray meets white, is unique to each shark and helps researchers to identify individual sharks in capture-recapture studies. Guadalupe Island is host to a relatively large population of great white sharks who, through a history of video and photographs showing their countershading lines, are the subject of an ongoing study of shark behaviour, migration and population size, Carcharodon carcharias, Guadalupe Island (Isla Guadalupe)
