Neptune has come almost full circle since it was first discovered in 1846, and on Aug. 20, it will be in a straight line with the sun and the Earth.
The newfound failed star, known as a brown dwarf, has been dubbed PZ Tel B. It is separated from its sun-like companion star, PZ Tel A, by a distance similar to that between Uranus and the sun in our solar system.
This infrared composite image of the two hemispheres of Uranus was obtained with Keck adaptive optics. The images were obtained on July 11 and 12, 2004. The representative balance of these infrared images which were selected to display the vertical structure of atmospheric features gives a reddish tint to the rings, an artifact of the process. The North pole is at 4 o'clock.
This infrared image from NASA's Spitzer Space Telescope shows what astronomers are referring to as a 'snake' (upper left) and its surrounding stormy environment. The sinuous object is actually the core of a thick, sooty cloud large enough to swallow dozens of solar systems. In fact, astronomers say the 'snake's belly' may be harboring beastly stars in the process of forming.
With a clear sky and a good pair of binoculars, you should have no trouble getting a glimpse of Uranus.
For the first few weeks of June, Mars and the star Regulus will appear to move closer together, offering a rare sky show.
This week, the huge asteroid Pallas reaches opposition, being opposite to the sun in Earth's sky, making it a prime target for avid skywatchers with telescopes.
Meteor shower tonight? Yep, peak viewing times for the Orionid meteor shower begins tonight (er... tomorrow) at 1 am.
