Ulysses cracks a cosmic peanut
Article Abstract:
Measurements taken by the Ulysses spacecraft indicates that the sun's heliosphere is shaped more like a peanut than a sphere. The heliosphere may balloon out at the solar poles because the solar wind is stronger there than at the sun's ecliptic, the plane through which the planets orbit.

Casting a wide net for cosmic rays
Article Abstract:
A group calling itself the Pierre Auger collaboration plans a series of water-tank detectors to detect high-energy cosmic rays. The as-yet unfunded detectors would gather rays of at least 10-to-the-20th electron volts, to provide clues to the mysterious source of such violent energies.

Radio galaxies: born in cosmic crackups?
Article Abstract:
Astronomers Andrew Wilson and Edward Colbert have proposed that radio galaxies result from the collision of two active galactic nuclei (AGNs). When the black holes at the center of AGNs collide, they coalesce into one, fast-spinning black hole, which emits radio waves.
