The Hubble space telescope has been in orbit for 23 years. Within this long time, Hubble space telescope has captured many stunning images like Saturn’s Aurorae during Equinox, Messier’s ancient stars and many more. Recently, the Hubble space telescope has photographed the Horsehead Nebula, which is a dark nebula in the constellation Orion in infrared wavelengths against the backdrop of the Milky Way.
The Horsehead Nebula is also known as Barnard 33. It is located about 1,500 light-years from the Earth in the constellation Orion. The Horsehead is a huge interstellar cloud of gas and dust, like other nebulae, and the light from a nearby star gives it a beautiful glow. The pink cast is from hydrogen gas behind the nebula, which is being lit up by Sigma Orionis, a five-star system. In other words, the Horsehead’s dramatic pillar is made of sterner stuff than the clouds surrounding the nebula. Here’s a video related to Horsehead Nebula.
In the image above, the Hubble space telescope clearly shows the dark mushrooms of the Orion Molecular Cloud, an incubator for the formation of massive stars. Besides, you will find two stars at the top ridge of the nebula, and one is emitting “harsh ultraviolet glare.”
