Messier 84 or M84, also known as NGC 4374, is an elliptical or lenticular galaxy in the constellation Virgo. Charles Messier discovered Messier 84 on 18 March 1781 in a systematic search for "nebulous objects" in the night sky. Messier 68 (also known as M68 or NGC 4590) is a globular cluster in the equatorial constellation Hydra. It was discovered by Charles Messier in 1780. William Herschel described it as "a beautiful cluster of stars, extremely rich, and so… Their population density decreases with increasing distance from the core. It has an active supermassive black hole at its core, which forms the primary component of an active galactic nucleus. zažil, můžete se těšit na jeho strašidelné historky s bubáky, strašáky, proradnými můrami a tajemnými povozy, při jejichž čtení se budete i trochu bát. 17×24 cm, pevná vazba, 64 stran, 198 Kč, 8,32 �, ISBN 978-80-271-0081-1 It is rotating rapidly with a projected rotational velocity of 19 km s−1.

With an apparent visual magnitude of 4.3, it is visible to the naked eye. However, it is the faintest of the five stars that form the "head" of the hydra. Based upon an annual parallax shift of 5.56 mas, it is located roughly 590 light years…
It is rotating rapidly with a projected rotational velocity of 19 km s−1. It has an X-ray luminosity of 2.8 × 1029 erg s−1. With an apparent visual magnitude of 4.3, it is visible to the naked eye. However, it is the faintest of the five stars that form the "head" of the hydra. Based upon an annual parallax shift of 5.56 mas, it is located roughly 590 light years… The inner layers of the nebula were formed some 1,500 years ago. The two ends of the nebula are marked by Fliers, lobes of fast moving gas often tinted red in false-color pictures. It is visible to the naked eye with an apparent visual magnitude of 4.48. The estimated distance to this star from the Sun, based upon an annual parallax shift of 8.75 mas, is around 370 light-years.
This is a double star with an angular separation of 2.6 ±0.1 arc second along a position angle of 265.1° ±1.0°, as of 2003. The brighter component is an A-type main sequence star with a stellar classification of A1 Vnn.
