One of the most photographed objects in space, the Horsehead Nebula is a cloud of gas and dust, dark and cold. It is only visible because it is behind a similar object that emits shinethe IC434 nebula.
Its distinctive shape was discovered in a photograph taken at the end of the 19th century, being cataloged as Barnard 33. It is located approximately 1,300 light years from Earth — in the constellation Orion — and has its shape due to a thick pillar of gas dense and dusty, giving the shape of a “horse’s head”.
Astronomers often use the Horsehead as a test of their observation skills, as this nebula is known as one of the most difficult objects to see visually in a standard-sized amateur telescope.
It is estimated that she will still have around five million years before disintegrating.
What is a nebula?
A nebula is a giant cloud of cosmic dust and gas that is located in space. It can be formed in an explosion of dying stars or a supernova — a powerful stellar detonation.
It may also be the name of a region of high star formation activity, a “nursery”, where new ones are born from the gravitational collapse of the material inside them. Nebulae play a crucial role in understanding stellar formation and evolution, as well as the chemistry of this environment.
