Latest Horsehead Nebula Stories
The Hubble Space Telescope is celebrating its 23rd year in orbit, and to commemorate the veteran observatory, NASA and the European Space Agency (ESA) have released an amazing image of the Horsehead Nebula.
A new image of the Pipe Nebula has been taken using the Wide Field Imager at the European Space Observatory's La Silla Observatory.
The cosmos is full of outstanding imagery, and a new image from NASA's Wide-field Infrared Survey Explorer, or WISE, has shot back another outstanding image back to Earth.
By popular demand, Hubble observes the horsehead nebulaHubble Space Telescope -- Rising from a sea of dust and gas like a giant seahorse, the Horsehead nebula is one of the most photographed objects in the sky.
Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...
Horsehead Nebula -- The Horsehead Nebula, a part of the optical nebula IC434 and also known as Barnard 33, was first recorded in 1888 on a photographic plate taken at the Harvard College Observatory. Its coincidental appearance as the profile of a horse's head and neck has led to its becoming one of the most familiar astronomical objects. It is, in fact, an extremely dense cloud projecting in front of the ionized gas that provides the pink glow so nicely revealed in this picture. We...
