Ring Nebula
Planetary Nebula M57 (also known as the Ring Nebula, NGC 6720 or Messier Object 57) is located in the constellation Lyra. It is among the most well known and recognizable examples of a planetary nebula.

RING NEBULA
A ring nebula is a huge cloud of dust and gas that is shaped like a ring. Pictured above is M-57, a ring nebula in Lyra which is 2,000 light-years from Earth and was generated by a dying star (this nebula was discovered by Ch. Messier).

Neighbouring nebula M17 is much more conspicuous, burning brightly with hot, massive class O stars. Such behemoths are absent from M17 SWex, but there is still time - such gigantic stars might need an extra boost to launch their formation.
This is the Ring Nebula which is a planetary nebula 5,000 light years away. Its central star is very dim. Planetary nebulae are much smaller than diffuse nebulae and therefore more difficult to observe.

After viewing the Ring Nebula, turn your telescope about 7-1/3 degrees to the south, and raise it by nearly 26 degrees. Here lies the Great Cluster in Hercules, also known as M13 and-NGC 6-205.

(a) The Ring Nebula in the constellation Lyra, a classic example of a planetary nebula, is about 1500 pc from us. It is about 0.
M57, the Ring Nebula, is probably the finest example of a planetary nebula anywhere in the sky. It was formed when a star about the size of the Sun neared the end of its life cycle and shed its outer shell of hydrogen gas.
On the other hand, there are certain Messier objects whose magnitude is low, but because they are tiny, they have a high surface brightness - a good example is the Ring Nebula, M57 in Lyra. This magnitude 9 planetary nebula is just 1.3 x 1.
The Ring nebula of the constellation Lyra, a typical planetary, has a rotational period of 132,900 years and a mass calculated to be about 14 times that of the earth's sun. Several thousand planetaries have been discovered in the Milky Way.
January's Hubble Heritage image is of NGC 6720, AKA M57, AKA the Ring Nebula, a planetary nebula. 2,300 light-years from us, the Ring Nebula lies in the constellation Lyra; this image covers approximately 2 arcminutes down (1.3 light-years).
M57 (NGC 6720) known as the Ring Nebula, is the finest planetary nebula in the skies. The ring itself should be clearly visible in medium scopes, while the fourteen magnitude central star may take a little longer.
The Eight-burst Nebula (NGC 3132), also known as the Southern Ring Nebula, is a bright planetary nebula approximately 2,000 light-years from Earth. It contains two faint stars lying close together.

The gas ejected will form a thin shell around the star. It is a planetary nebula. Here is the Ring nebula, M57, easily visible through a small telescope. Some others were taken by the Hubble Space Telescope.
The round soap bubbles you made as a child (or still do!) look like rings for the same reason. Indeed, many of the planetary nebulae first seen, like the Ring Nebula in Lyra and the Helix Nebula in Aquarius look like rings.
