Sharpless 101 (Sh2-101) is an emission nebula, a glowing cloud of interstellar gas and dust, located in the constellation Cygnus. It is also known as the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically.
It lies at a distance of about 8,000 light-years from Earth and measures 70 light years across. The nebula resides in the Orion Arm of our galaxy, in a rich Milky Way field full of interesting stars and deep sky objects.
