... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

During the course of ten nights of observing (UT 27 April - 6 May 1996), the KPNO Mayall 4m Telescope was used to image the Hubble Deep Field in the near infrared. The IRIM camera employs a 256 x 256 Rockwell NICMOS-3 HgCdTe array, with a scale of approximately 0".6/pixel at the 4m f/15 Cassegrain focus. ... A paper on the HDF/IRIM data (observations, reductions, catalogs and basic analysis) is in preparation, titled "Near Infrared Properties of the Hubble Deep Field" by Dickinson et al. ...

This image, which is a composite of images taken in several colors by the New Horizons Multispectral Visible Imaging Camera (MVIC), illustrates the remarkable diversity of structures in Jupiter's atmosphere. The image, whose colors are similar to what a voyager on New Horizons would see, is taken near the terminator, the boundary between day and night, and shows relatively small-scale turbulent polar structures as well as deep holes in the clouds and extended zonal structures at other latitudes. ...
