Asteroid 1998 WT24 Passes Near Earth
24.12.2001

Last week, an asteroid approached unusually close to the Earth. Passing well outside the orbit of our Moon, Asteroid 1998 WT24 posed no danger, but became bright enough to see with binoculars and to track with radar. Pictured above, the kilometer-sized asteroid was imaged crossing the sky on December 14, two days before closest approach.

Nova Cygni 1992
27.12.1995

In 1992 a tremendous explosion occurred in the constellation of Cygnus. Dubbed Nova Cygni 1992, this event most probably occurred in an accretion disk binary system. Astronomers hypothesize that this system's white dwarf had so much gas dumped onto it's surface that conditions became ripe for nuclear fusion.

Quasar in an Elliptical Galaxy
9.04.1998

Where do quasars live? Quasars are the brightest objects in the universe, so bright they can be seen from across the universe. Observations continue to show that most quasars are surrounded by a relatively faint nebulous patch. Astronomers are trying to identify the nature of these patches.

Venus Unveiled

The surface of Venus is perpetually covered by a veil of thick clouds and remains hidden from even the powerful telescopic eyes of earth-bound astronomers. But in the early 1990s, using imaging radar...

Kalamalka Lake Eclipse
1.09.2007

Recorded on August 28th, this serene total lunar eclipse sequence looks southwest down Kalamalka Lake toward the lights of Coldstream, British Columbia. An exposure every 4 minutes captured the Moon's position and eclipse phase, until the Moon set behind the town lights and a hill on the horizon.

Space Station in the Sun

Still bathed in sunlight, the International Space Station tracked through night skies above Hombressen, Germany on May 12. From a range of at least 360 kilometers, astronomer Dirk Ewers was able to record...

Contemplating the Sun

Have you contemplated your home star recently? Featured here, a Sun partially eclipsed on the top left by the Moon is also seen eclipsed by earthlings contemplating the eclipse below. The spectacular menagerie...

Counting Falling Stardust
23.11.2001

In the clear, dark and moonless predawn hours of November 18, Greenbelt, Maryland's local baseball field was packed. The crowd stared skyward and occasionally conversed in hushed and reverent tones. "How many did you count?" a man asked.

Shuttle Engine Blast
26.01.2002

The Space Shuttle Discovery's orbital maneuvering system (OMS) engine firing produced this dramatic flare as it cruised "upside down" in low Earth orbit. Discovery was named for a ship commanded by Captain James Cook RN, the 18th Century English astronomer and navigator.

The Reflecting Dust Clouds of Orion
21.01.2003

In the vast Orion Molecular Cloud complex, several bright blue nebula are particularly apparent. Pictured above are two of the most prominent reflection nebulas -- dust clouds lit by the reflecting light of bright-embedded stars. The more famous nebula is M78, on the upper right, cataloged over 200 years ago.
