NGC 4565. An edge-on spiral galaxy in the constellation Coma Berenices. Some 55 million light years away, this galaxy looks like a frosty needle in the depths of intergalactic space. Some also call it the "Flying Saucer" galaxy. Visible in a 6-8 inch (or larger) telescope.
The Double Cluster. A unique set of two rich open star clusters in the constellation Perseus. Visible as a fuzzy patch to the naked eye, this pair is stunningly beautiful in a telescope. Easy to see, not to be missed.
The Castaway Cluster. Set in the most star-rich section of the Milky Way and surrounded by dark nebulae that look like holes in space itself, the "Castaway Cluster" is an achingly beautiful sight. It's located just above the spout of the "
Teapot" of Sagittarius. Also known as NGC 6520, this cluster was named by astronomy writer Stephen J. O'Meara because it looks like a tiny island in a tempestuous sea of stars. It reminded him of the story of the castaway Robinson Crusoe.
The Veil Nebula. A system of three ethereal nebulae in the constellation Cygnus. They were formed by the supernova explosion of one (and possibly two) stars some 18,000 years ago. The Veil spans more than 3 degrees of sky, and is hard to fit into a single field of view of a telescope.
A stunning sight, just off the star epsilon Cygni. Can be seen in binoculars in very dark sky.The "
E.T. Cluster". In Cassiopeia, this small open cluster is also cataloged as NGC 457. Its name comes from a more-than-passing resemblance to the famed character in Steven Spielberg's "E.T.". Visible from northern skies only.
The Jewel Box Cluster. A dazzling open star cluster in the Crux (the Southern Cross), it appears as a fuzzy star just off the star Mimosa at one arm of the cross. Early astronomers actually catalogued this cluster as a star, kappa Crucis, before telescopes revealed its true nature. Binoculars or a small scope are all you need to see this young cluster full of new blue-white stars.
47 Tucanae. The second brightest globular cluster in the sky, but perhaps the most visually appealing. This cluster is as old as the Milky Way itself... some 12 billion years. You can see it in the deep-southern constellation Tucana with your unaided eye. It looks like a bundle of diamonds in even the smallest telescope.
M11. A large, old open star cluster in Scutum, M11 is sometimes called the "Wild Duck" cluster because of its resemblance to a flock of ducks or geese flying in a V-shaped formation. Observe it with low magnification and work your way higher. But take your time... see as much detail as you can.M22. A loosely-packed globular cluster in Sagittarius. Called by some the "Arkenstone of the Sky", M22 is a lovely sight on a warm northern summer night. One of the finest sights in a constellation packed with fine sights.
NGC 5128. A giant elliptical galaxy caught in the act of eating a dusty edge-on spiral galaxy, NGC 5128 in the southern constellation Centaurus is one of the most intriguing galaxies in the heavens.

New Findings on Hot Quark Soup Produced at RHIC
New Findings on Hot Quark Soup Produced at RHIC
Scientists to present latest findings from heavy ion collisions at APS meeting
Scientists to present latest findings from heavy ion collisions at APS meeting
EVENT: Scientists from the U.S. Department of Energy’s Brookhaven National Laboratory and the Relativistic Heavy Ion Collider (RHIC), the world’s largest particle accelerator dedicated to nuclear physics research, will present compelling new findings about the nature of the “perfect” liquid created in near-light-speed collisions of gold ions at RHIC.
WHEN: Monday, February 15, 2010, 9:30 a.m.
WHERE: The "April 2010" meeting of the American Physical Society (APS), Marriott Wardman Park Hotel, Washington, D.C., Press Room/Briefing Room, Park Tower 8222
DETAILS: The Relativistic Heavy Ion Collider (RHIC) is a 2.4-mile-circumference particle accelerator/collider that has been operating at Brookhaven Lab since 2000, delivering collisions of heavy ions, protons, and other particles to an international team of physicists investigating the basic structure and fundamental forces of matter. In 2005, RHIC physicists announced that the matter created in RHIC’s most energetic collisions behaves like a nearly “perfect” liquid in that it has extraordinarily low viscosity, or resistance to flow. Since then, the scientists have been taking a closer look at this remarkable form of matter, which last existed some 13 billion years ago, a mere fraction of a second after the Big Bang. At this press event, scientists will present new findings, including the first measurement of temperature very early in the collision events, and their implications for the nature of this early-universe matter.
