The horsehead nebula

The Horsehead Nebula (also known as Barnard 33 or IC 434) is a dark nebula in the Orion constellation. The nebula is located just below Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. It is approximately 1,500 light years from Earth, and is approximately 3.5 light years wide.
One of the most identifiable nebulae in the sky, it is part of a swirling cloud of dark dust and gases, shaped like a horse's head (hence its name). Also known as Barnard 33, the unusual shape was first discovered in 1888 on a photographic plate taken at the Harvard College Observatory.
The red glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming.

Boomerang nebula

The Boomerang Nebula (also called the Bowtie Nebula) is a nebula located 5,000 light-years away from Earth in the Centaurus constellation. The nebula is at 1 kelvin; the coldest place known outside a laboratory. The Boomerang Nebula is formed from the outflow of gas from a star at its core. The gas is moving outwards at a speed of about 600,000 km/h and expanding rapidly as it moves out into space. This expansion is the cause of the nebula's very low temperature.
The Boomerang Nebula was photographed in detail by the Hubble Space Telescope in 1998. It is believed that the nebula is a star or stellar system evolving toward the planetary nebula phase.
Keith Taylor and Mike Scarrott called it the Boomerang Nebula in 1980 after observing it with a large ground-based telescope in Australia. Unable to see the detail that only Hubble can reveal, the astronomers saw merely a slight asymmetry in the nebula's lobes suggesting a curved shape like a boomerang. The high-resolution Hubble images indicate that 'the Bow tie Nebula' would perhaps have been a better name.
To make it more interesting i made some boomerang UFOs in this painting.

Minkowski’s butterfly

Wings of a butterfly nebula
This is my oil on canvas painting of Minkowski’s butterfly(M2-9 or wings of a Butterfly Nebula), a bipolar planetary nebula in the constellation Ophiuchus.
