Cassini Collects Particles Accelerated by the Sun.

Dec 11, 2003 NASA's Saturn-bound spacecraft, Cassini, has made the first observation of interstellar pickup ions beyond the orbit of Jupiter. These are neutral particles in the solar system that get ionized when they get too close to the Sun, and then travel outwards with the solar wind. These ions have been seen near the Earth, but never out past the orbit of Jupiter. By measuring these particles, Astronomers will have a better understanding of the low-density gas and dust that exists between the stars.

Best Ultraviolet Image of Andromeda galaxy.

Dec 11, 2003 NASA's galaxy evolution Explorer (GALEX) has captured the most sensitive and comprehensive ultraviolet images ever taken of the Andromeda galaxy, M31. By studying the Galaxy in the ultraviolet spectrum, Astronomers can study some of the fundamental processes that lead the formation of new stars. A new collection of images included Andromeda, as well as the globular cluster M2, and the sky in the constellation of Bootes. GALEX was launched in April, 2003, and will map the sky in the ultraviolet spectrum, looking back to 10 billion years ago.
