Nebulae, also known as "star smoke," are beautiful clouds of gas and dust in the universe.
Most nebulae are formed when gas and dust collect and gravitationally converge to form a nebula during the birth of a star.
The ‘Iris Nebula’ is a reflection nebula in the constellation Cepheus, a cold interstellar cloud of dust and gas that does not emit light itself but reflects light from nearby stars.
The Iris Nebula is about 6 light-years across.
It is named the ‘Iris Nebula’ because it looks like a flower blooming in space.
