Out there in the deep reaches of outer space, an incredible trio of stellar nurseries is booming with newborn stars. Astrophotographer Terry Hancock captured a dazzling image of this cosmic trio from Fremont Michigan. Each one of these nebulae are unique with their own awe-inspiring stories and intergalactic happenings. Let your mind take a journey into each nebula as we describe them below and imagine the incredible possibilites of unexplored worlds and stellar wonders. 


 Flaming Star, Tadpoles and Spider Nebulae IC405, IC410, IC417 

A nebula is a cloud of gas and dust in space. Some nebulae are regions where new stars are being formed, while others are the remains of dead or dying stars. Nebulae come in many different shapes and sizes. There are four main types of nebulae: planetary nebulae, reflection nebulae, emission nebulae, and absorption nebulae. Nebula can be as vast as in million light years across.

Right side on the image giant IC 405 also known as the Flaming Star Nebula, or Caldwell 31 is an emission/reflection nebula in the constellation Auriga. Nebula is surrounded blue star AE Aurigae, it is a runaway star in the constellation Auriga; it lights the Flaming Star Nebula. It is an irregular variable star and is located near the emission nebula IC 410, the open clusters M38 and M36, and the naked-eye K-class star Hassaleh. A runaway star is one that is moving through space with an abnormally high velocity relative to the surrounding interstellar medium. The nebula is about 5 light-years across, and lies about 1,500 light-years away from Earth.

Bottom middle of the image IC 410 also known as the Tadpole nebula because of its northeastern filaments, is an emission nebula large visible in the constellation of Auriga, it is linked to the open cluster NGC 1893 formed by young massive stars rather dispersed. Atoms of hydrogen and other elements in the nebula are made to emit their own light after being excited by this starlight, a sort of cosmic black-light effect. The nebula itself is home to a pair of intriguing structures popularly known as the "tadpoles." The cluster, consisting of the band of stars to the lower-left of center, is referred to as NGC 1893. The ultraviolet light produced by these stars powers the nebula. The tails of the tadpoles are caused by the radiation pressure and solar wind from the stars of NGC 1893. The nebula is about 100 light-years across and lies about 12,000 light-years away.

Left from the Flaming Star and Tadpole nebula, IC 417, sometimes known as Spider Nebula is a large emission nebula visible in the constellation of Auriga, it is linked to the 'open cluster Stock 8. A cluster of young stars called "Stock 8" can be seen at center right. IC 417 It is in the outer part of the Milky Way, almost exactly in the opposite direction from the galactic center. This region was chosen as the subject of a research project by a group of students, teachers and scientists as part of the NASA/IPAC Teacher Archive Research Program (NITARP) in 2015. Nebula lies about 10,000 light-years away from the Earth.
