NASA is releasing today a Hubble Space Telescope (HST) photograph of the most remarkable star forming region in the Local Group of Galaxies, 30 Doradus. The photograph shows about 60 stars within a central tight cluster in 30 Doradus. In contrast, earlier photographs with ground-based telescopes, supplemented by mathematical analysis, have shown only 27 stars in the tight cluster, which is called R136. Before the ground-based studies showed that so many stars are present in R136, some astronomers thought it was a single, supermassive object, with as much as 3,000 times the mass of the Sun. This recent HST photograph shows even more individual stars within R136. Furthermor…

The European Space Agency's Faint Object Camera aboard NASA's Hubble Space Telescope, has successfully taken its first engineering test pictures of the heavens. This "first light" picture for the Faint Object Camera (FOC) is the culmination of several weeks of intensive check-out and testing of the camera, following the launch of the Hubble Space Telescope (HST) last April 24.

The image on the right is a portion of the first image returned by the Wide Field/Planetary Camera on the Hubble Space Telescope (HST). On the left is a ground based image of the same area of the sky. The object shown in these images is a double star: the pair of stars is well separated in the HST image but blurred together in the ground based image. View the full article

On the right is part of the first image taken with NASA's Hubble Space Telescope's (HST) Wide Field/Planetary Camera. It is shown with a ground-based picture from a Las Campanas, Chile, observatory of the same region of the sky. The Las Campanas picture was taken with a 100-inch telescope and it is typical of high-quality pictures obtained from the ground. All objects seen are stars within the Milky Way galaxy..
