Westerhout 50 (W50) or SNR G039.7-02.0, also referred to as the Manatee Nebula, [1] is a supernova remnant located in the constellation Aquila, about 18,000 light years away. In its centre lies the micro-quasar SS 433 , whose jets are distorting the remnant's shell.
The mass of the nebula is estimated at about 0.6 solar masses, while the progenitor star was likely about 2.3 times the mass of the Sun. [4] NGC 2818 presents a complex morphology, and overall has bipolar structure, making it a bipolar nebula. The two lobes are somewhat broken and irregular.
NGC 3576 is a bright emission nebula in the Sagittarius arm of the galaxy a few thousand light-years away from the Eta Carinae nebula. It is also approximately 100 light years across and 9000 light-years away from Earth. [3] It was discovered by John Frederick William Herschel on 16 March 1834. [4] This nebula has received six different ...
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...
NGC 2736 (also known as the Pencil Nebula) is a small part of the Vela Supernova Remnant, located near the Vela Pulsar in the constellation Vela. The nebula's linear appearance triggered its popular name. It resides about 815 light-years (250 parsecs) away from the Solar System. It is thought to be formed from part of the shock wave of the ...

The overall nebula with smaller hole shown in context. NGC 1999, also known as The Cosmic Keyhole, [1] [2] is a dust-filled bright nebula with a vast hole of empty space represented by a black patch of sky, as can be seen in the photograph. It is a reflection nebula, and shines from the light of the variable star V380 Orionis.
Astrophotography of the NGC6188 nebula in narrowband technique and Hubble palette (SHO). NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova.
