European Southern Observatory
The European Southern Observatory (ESO) is an intergovernmental organization founded in 1962 and supported by 16 member states and host country Chile. ESO designs, builds, and operates some of the world's most advanced ground-based astronomical observatories—such as La Silla, Paranal (home to the Very Large Telescope and other survey instruments), and the Atacama Large Millimeter/submillimeter Array (ALMA)—and is currently constructing the Extremely Large Telescope (ELT).

Lunar Close-Up
12/02/1999
Late last month, NASA's Lunar Prospector spacecraft moved in for a closer look at the Moon. Now entering an extended mission phase, controllers have reduced the altitude of this polar lunar orbiter from 100 kilometers to about 30 kilometers (18 miles). Having mapped global properties and recorded evidence for water-ice at the lunar poles, the lower orbit allows Prospector's instruments to gather valuable confirming data at higher resolutions. The new orbit is not without some risk, though, and maneuvers are required every 28 days to maintain it. Should the maneuvers fail to be performed, the spacecraft would impact the surface only two days later. This lunar close-up was recorded by the European Southern Observatory's new WFI camera. It shows dramatic shadows and contrasting terrain near the prominent Gassendi crater at the northern edge of the Moon's Mare Humorum.
