One of the best examples of this is the Crab Nebula, in Taurus. The supernova event was recorded in the year 1054 and is labeled SN 1054. The compact object that was created after the explosion lies in the center of the Crab Nebula and its core is now a neutron star. Still other nebulae form as planetary nebulae.
Lagoon Nebula is a large, low-density cloud of partially ionized gas. [1] Astrophysical plasma is plasma outside of the Solar System. It is studied as part of astrophysics and is commonly observed in space. [2] The accepted view of scientists is that much of the baryonic matter in the universe exists in this state. [3]
[1] [2] They are believed to be a common feature of the evolution of planetary nebulae, but can only be resolved in the nearest examples. [2] They are generally larger than the size of the Solar System (i.e. the orbit of Pluto ), with masses of around 0.00001 times the mass of the Sun , which is comparable to the mass of the Earth .
The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .
The Rosette Nebula is an example of an unusual shape that an elephant trunk can assume. It has a double helix structure instead of the normal straight column. [ 10 ] The double helix is caused by the presence of magnetic fields and electric currents lined up along the trunk axis of the trunks.
The nebula's color depends on its chemical composition and degree of ionization. Due to the prevalence of hydrogen in interstellar gas, and its relatively low energy of ionization, many emission nebulae appear red due to strong emissions of the Balmer series. If more energy is available, other elements will be ionized, and green and blue ...

The gas temperatures in outer space can vary widely. For example, the temperature in the Boomerang Nebula is 1 K (−458 °F), [43] while the solar corona reaches temperatures over 1,200,000–2,600,000 K (2,200,000–4,700,000 °F). [44] Magnetic fields have been detected in the space around just about every class of celestial object.
