ASTROPHYSICS IN 1994

1994 was the year in which we saw the first images from the repaired H ubble Space Telescope; the probable detection of a diffuse intergalact ic medium, a black hole in M87, and an enormous primordial deuterium a bundance; the discovery of the first (and second) superluminal objects within our own galaxy; not to mention the demise of the Jovian dinosa urs. But, as always, most astronomers continued to work away on the pr ojects that have interested them for years or decades, and we attempt also to report some progress in broader areas, including cooling flows , extragalactic globular cluster populations, disk instabilities, phas es of the interstellar medium, and brown dwarfs among microlenses and other populations. Several sections of short items range from the obvi ous to the remarkable to the unbelievable. As in previous years, the o rdering of the topics attempts to preserve the near-to-far custom of e lementary astronomy textbooks.
