Messier 105 or M105, also known as NGC 3379, is an elliptical galaxy 36.6 [2] million light-years away in the equatorial constellation of Leo. It is the biggest elliptical galaxy in the Messier catalogue that is not in the Virgo cluster. [8]

2024年8月25日 · Hubble peered into the core of M105 (also known as NGC 3379) and measured the motions of stars swirling around its center. These observations proved that a supermassive black hole resides at the galaxy’s heart. According to recent estimates, this black hole could be up to 200 million times as massive as our Sun.

M105（也稱為NGC 3379）是一個位於獅子座的橢圓星系，由皮埃爾·梅香（Pierre Méchain）於1781年3月24日所發現。M105擁有一個超大質量黑洞。

1997年1月13日 · The three galaxies above are believed to contain central, supermassive black holes. The galaxy NGC 4486B (lower-left) shows a double nucleus (lower-right). The images of NGC 3377 and NGC 4486B are 2.7 arcseconds on a side, and for NGC 3379 the size is 5.4 arcseconds; the lower-right is a blow-up of the central 0.5 arcseconds of NGC 4486B.

The bright elliptical galaxy NGC 3379 (M105) in Leo, from a 5-minute blue-light exposure with a Tektronix 2048x2048 CCD at the 2.1-meter telescope of Kitt Peak National Observatory by Bill Keel and Lisa Frattare. North is at the top and east to the left, for direct comparison with a …

These observations proved that a supermassive black hole resides at the galaxy’s heart. According to recent estimates, this black hole could be up to 200 million times as massive as our Sun.

Messier 105 (NGC 3379) is an elliptical galaxy located in the constellation Leo in the Leo I Group of galaxies. M105 is 36600000 light years away from Earth. M105 is best viewed during early spring, is magnitude 10.2, and can be viewed with small telescope. M105 is 5.4' x …

2007年4月25日 · NGC 3379 (M-105) is a type E1 elliptical galaxy. M-105 appears visually in Kopernik Observatory's 20 inch telescope as a bright, round, smudge, with a very bright center. It forms a small triangle with NGC 3384, a bright lenticular galaxy, and …

We combine Hubble Space Telescope spectroscopy and ground-based integral-field data from the SAURON and OASIS instruments to study the central black hole in the nearby elliptical galaxy NGC 3379. From these data, we obtain kinematics of …

2008年7月29日 · We report the discovery of a faint (L_x ~ 4 10^37 erg/s, 0.5-2 keV), out-flowing gaseous hot interstellar medium (ISM) in NGC 3379. This represents the lowest X-ray luminosity ever measured from a hot phase of the ISM in a nearby early type galaxy.
