This week the second planet from the sun will pass directly in front of the Pleiades star cluster. It's a rare sunset conjunction that's easy to find with the unaided eye, but best seen through binoculars or a small telescope.

New observations by University of Michigan astronomers add weight to the theory that the most massive stars in the universe could form essentially anywhere, including in near isolation; they don't need a large stellar cluster nursery.

Omega Centauri -- Discovered by Edmond Halley in 1677. About 10 million stars orbit the center of this globular cluster - named Omega Centauri - as this giant globular cluster orbits our Galactic center. Recent evidence indicates that Omega Centauri is by far the most massive of the about 150 known globular clusters in the Milky Way. Omega Centauri, cataloged as NGC 5139, spans about 150 light years across, lies about 15,000 light years away, and can be seen without visual aid...

The Hyades -- The Hyades are an open star cluster located in the constellation Taurus. The closest star cluster to Earth, it is centered some 151 light years away. The brightest star in this direction is Aldebaran, but it is not a member of the cluster, being located at just over 40% of the distance. Not counting Aldebaran, approximately 300 stars are known or suspected to be members of the cluster; most are not visible to the naked eye. The stars of the Hyades are associated with one...

pawl
  • A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
The word 'pawl' probably comes from a Latin word meaning 'stake'.
