The Weekend Image : Andromeda Galaxy's Supermassive Black Hole

The Hubble Space Telescope image below centers on the 100-million-solar-mass black hole at the hub of the neighboring spiral galaxy M31, or the Andromeda galaxy, the only galaxy outside the Milky Way visible to the naked eye and the only other giant galaxy in the local group. This is the sharpest visible-light image ever made of the nucleus of an external galaxy. The event horizon, the closest region around the black hole where light can still escape, is too small to be seen, but it lies near the middle of a compact cluster of blue stars at the center of the image.

The compact cluster of blue stars is surrounded by the larger "double nucleus" of M31, discovered with the Hubble Space Telescope in 1992. The double nucleus is actually an elliptical ring of old reddish stars in orbit around the black hole but more distant than the blue stars. When the stars are at the farthest point in their orbit they move slower, like cars on a crowded freeway. This gives the illusion of a second nucleus.

The blue stars surrounding the black hole are no more than 200 million years old, and therefore must have formed near the black hole in an abrupt burst of star formation. Massive blue stars are so short-lived that they would not have enough time to migrate to the black hole if they were formed elsewhere.
Astronomers are trying to understand how apparently young stars were formed so deep inside the black hole's gravitational grip and how they survive in an extreme environment.

The fact that young stars are also closely bound to the central black hole in our Milky Way galaxy suggests this may be a common phenomenon in spiral galaxies.

Tod R. Lauer of the National Optical Astronomy Observatory in Tucson, Ariz., assembled the image below of the nuclear region by taking several blue and ultraviolet light exposures of the nucleus with Hubble's Advanced Camera for Surveys high-resolution channel, each time slightly moving the telescope to change how the camera sampled the region. By combining these pictures, he was able to construct an ultra-sharp view of the galaxy's core.

Comments

The fact that young stars are also closely bound to the central black hole in our Milky Way galaxy suggests this may be a common phenomenon in spiral galaxies.

The Magellanic Clouds are visible to the naked eye, too.

With reference to the book ‘Science Of Time And The Theory Of Everything’ (Galactic-egg) by Bhausaheb Bhosle based on space time energy mass constants (Dynamic dimensional) of oscillating systems of non-dual mind, matter and time.

This ancient theory (Surya-Siddhanta) – The theory of harmonics has been completely solved and the details of the theory (constants) in terms of time (continuity of moments) has been linked as a whole as one time of manifestation determined by frequencies per second and their phase changes to determine the final oscillating centre as the final space time energy mass oscillating constant before the remanifestation retaining the continuity of moments (time).

This is the mysterious book encompassing all the sciences as one science of time including mathematics, geometry, trigonometry even in nano space time energy mass scale (genetic) to determine the genetic drive (developmental dynamics of the fetus – The Golden Egg (Hiranya garbha) in galactic space time energy mass scale as non- dual memory energy time) retaining the same word and the same meaning.

We wish to publish it together with our original book. Can you please help us so that this knowledge is made public for all those interested in it.

This is our only goal (aim). Let a hundred flowers bloom is our wish before the start of the New Age.

This book has been already referred to the astronomical research centres in Asia and Europe

I had got one of my manuscript published in IJERD journal in August 2013. Now i had got my

book 'Science of Time ans The Theory of Everything' by author Bhausaheb Bhosle published by

publisher PublishAmerica.
