The images and illustration reveal that the Andromeda Galaxy's (M31's) core is composed of a ring of old, red stars and a newly discovered disk of young, blue stars. The disk is trapped within a supermassive black hole's gravitational field.

2005年9月20日 · The images and illustration reveal that the Andromeda Galaxy's (M31's) core is composed of a ring of old, red stars and a newly discovered disk of young, blue stars. The disk is trapped within a supermassive black hole's gravitational field.

A Hubble WFPC2 image of the core of M31. Astronomers believe the two bright objects are a ring of red stars and a disk of blue stars.

2012年1月11日 · This zoom dives deep into the nucleus of the neighboring spiral galaxy M31, also known as the Andromeda galaxy. The new Hubble Space Telescope image centers on the 100-million-solar-mass black hole at the core of the galaxy and the young blue stars surrounding the black hole....

Andromeda, indexed as M31, is so close to our own Milky Way Galaxy that it gives a unique perspective into galaxy composition by allowing us to see into its core. Billions of stars swarm around a center that has two nuclei and likely houses a supermassive black hole over 5 million times the mass of our Sun .

1993年7月20日 · The smaller galaxy's core is the only surviving fossil relic of the galactic collision. A problem with the collision scenario is that the remnant core should be torn apart by the massive black hole hypothesized to dwell at the exact center of M31. The suspected black hole would be located in the middle of the dimmer peak uncovered by HST.

2018年7月23日 · This single event explains many observations that were previously considered separately: M31’s compact and metal-rich satellite M32 13 is likely to be the stripped core of the disrupted galaxy,...

Traditionally, images of this neighboring spiral galaxy reveal a luminous core enveloped by its serene, stellar rings. However, my venture was aimed at unmasking what lies within the heart of Andromed...

2024年11月28日 · A relatively short project, I imaged the core of M31 over three nights; SNR was naturally high due to high brightness. Minimal processing to obtain a natural view of this beauty with small details galore. One of the surprising elements in this picture is how many small galaxies I can count BEHIND M31.
