  2. Orion Nebula - Wikipedia

    en.wikipedia.org/wiki/Orion_nebula

    The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion.

  3. Nebula - Wikipedia

    The term was coined by Steve Mandel who defined them as "high galactic latitude nebulae that are illuminated not by a single star (as most nebula in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way. As a result, these nebulae are incredibly faint, taking hours of exposure to capture.

    The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. [6] [7] [8] It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. [9]

    It was an object first noted of interest using the IRAS satellite by Fred Gillett and his associates in 1986, as a pointlike light source [d] [16] and its nature was found in 1989 by Gillett et al. [17] The planetary nebula's central star is a blue star. The nebula, designated GJJC1, is likely about only 6,000 years old. [3]

    The stars targeted were the ones detected from the HST/NICMOS Paschen-α survey of the Galactic Centre. V4998 Sagittarii was one of the stars observed and it was given another designation of DWC2011 92. [9] In 2014 a group decided to study the LBVs in the Quintuplet cluster. The mass of the star's nebula was measured at 6.2 M ☉.

  8. Messier 28 - Wikipedia

    en.wikipedia.org/wiki/Messier_28

    Messier 28 or M28, also known as NGC 6626, is a globular cluster of stars in the center-west of Sagittarius.It was discovered by French astronomer Charles Messier in 1764. [11] [a] He briefly described it as a "nebula containing no star... round, seen with difficulty in 3 1 ⁄ 2-foot telescope; Diam 2′."

  9. Messier 30 - Wikipedia

    en.wikipedia.org/wiki/Messier_30

    The cluster is following a retrograde orbit (against the general flow) through the inner galactic halo, suggesting that it was acquired from a satellite galaxy rather than forming within the Milky Way. [8] It is in this epoch 22.2 kly (6.8 kpc), from the center of the galaxy, compared to an estimated 26 kly (8.0 kpc) for the Sun. [12]
