PIX4618577: Hubble Nebula (NGC 2261) in Unicorn - NGC 2261, Hubble's variable nebula - The Hubble Nebula is a weak nebulosite that surrounds the star R Monocerotis (R Mon), the bright star at the bottom of the nebula. The mass of the star R Mon is about 10 times that of the sun. It is approximately 2600 light years away and is only 300,000 years old. Image obtained by Siding Spring's 3.9m telescope. Hubble's variable nebula is in Monoceros and was the first object to be photographed with the famous 200 inch Hale Telescope at Palomar in 1948. This curious object is a reflection nebula in which is embedded the star R Monocerotis. Variations in the appearance of the nebula were noted by the American astronomer Edwin Hubble in 1916. They are probably caused by opaque clouds of dust passing between the hidden star and the outskirts of the nebula we see, the moving shadows changing the apparent form of the glowing dust in an irregular way. This picture was made from three AAT plates taken over several years and subtle colour changes around the edge of the nebula are indications of the variability / Bridgeman Images

PIX4618887: Nebula NGC 3372 in the Carene - The Carina nebula, NGC 3372 - The Carene nebula is located about 7000 years from the Earth. It is home to many hot stars, including the star Eta Carinae in the centre of the nebula. Image obtained by Siding Spring's 3.9m telescope. The brightest part of the Milky Way, as seen by the unaided eye, lies in the southern constellation Carina. Here there are an unusually large number of young, hot stars. Their radiation is rich in energetic ultraviolet light. Many of these stars were born within the spectacular Carinae nebula, seen here. The nebula is a cloud of glowing gas composed mostly of hydrogen. It excited by ultrviolet light from the embedded stars. This dostictive emission radiation is responsible for the red colour. About a quarter of the nebula is made of helium gas, the second most abundant element in the universe after hydrogen, and all the other chemical elements account for only a few percent of the total mass. The brightest star in the nebula is known as eta Carinae. This remarkable object is one of the most luminous and most massive stars known / Bridgeman Images

PIX4581507: The Pleiades cluster with zodiacal light - The Pleiades cluster with zodiacal light - The zodiacal light that extends here from the bottom right of the image to the Pleiades and the Taurus, comes from the reflection of the light of the Sun on the countless interplanetary dust; it draws the plane of the Solar System. The faint cone of light extending from the horizon along the ecliptic is known as zodiacal light. It comes from the reflexion of the sun's light off tiny interplanetary dust particles in the plane of the solar system. One can see it here from the bottom right of the image to beyond the Pleiades cluster in the center of the image / Bridgeman Images
