- Hubble's 100,000th Orbit
The Hubble Space Telescope has just recently completed its 100,000th orbit around Earth today, August 11, 2008. The telescope reached that milestone above the Pacific Ocean (Illustration above). It has been a long journey for this famous telescope, 18...
- The Pacman Nebula.
NGC 281 is an H II region, located about 9,200 light years from Earth in the constellation of Cassiopeia. It is also known as the Pacman Nebula for its resemblance to the video game character. It includes an open cluster IC 1590 and the...
- The Fox Nebula
Fox Fur Nebula is located in NGC 2264 Region and lies in the constellation of Monoceros.This interstellar beast is formed of cosmic dust and gas interacting with the energetic light and winds from hot young stars. The shape, visual texture,...
- The Heart Nebula
The Heart Nebula, IC 1805 lies 7500 light years away in the constellation Cassiopeia. Its an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons. It's intense red output...
- The Red Spider Nebula
Centred on a dying star, The Red Spider Nebula expels scorching stellar winds at 300 kilometres per second, generating waves 100 billion kilometres high. These supersonic shock waves, caused by the heating of compressed gas and expansion of the nebula,...

NGC 6280 Nebula
NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in the constellation Vulpecula.
Emission nebulae are clouds of high temperature gas. The atoms in the cloud are energized by ultraviolet light from a nearby star and emit radiation as they fall back into lower energy states (in much the same way as a neon light). These nebulae are usually red because the predominant emission line of hydrogen happens to be red .
Velpecula is a faint constellation in the northern sky.
