NGC 3115 (also Spindle Galaxy, Caldwell 53, MCG -1-26-18, UGCA 199 and PGC 29265) is a magnitude +9.1 lenticular galaxy located 30 million light-years away in the constellation Sextans.

The galaxy was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflector at Windsor Road, Slough,on the 22nd February 1787.

Right Ascension 10h 05m 13.8s, Declination Dec Dec -07 43' 07"

NGC 3115



This is NGC 3115, a galaxy located about 32 million light years from Earth. This composite image contains X-rays from Chandra as well as optical data from the Very Large Telescope. Using the new Chandra image, astronomers have imaged the flow of hot gas as it falls toward the supermassive black hole in the center of NGC 3115. This is the first time such a flow has been clearly imaged in any black hole. The Chandra data also provide evidence that the black hole in NGC 3115 has a mass of about two billion times that of the Sun. This would make NGC 3115 the host of the nearest billion-solar-mass black hole to Earth.

NGC 3115: Chandra Images Gas Flowing Toward Black Hole

n3115_w1.jpg

The galaxy NGC 3115 is shown here in a composite image of data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope (VLT). Using the Chandra image, the flow of hot gas toward the supermassive black hole in the center of this galaxy has been imaged. This is the first time that clear evidence for such a flow has been observed in any black hole.

NASA's Chandra Observatory Images Gas Flowing Toward Black Hole

The flow of hot gas toward a black hole has been clearly imaged for the first time in X-rays. The observations from NASA's Chandra X-ray Observatory will help tackle two of the most fundamental problems in modern astrophysics: understanding how black holes grow and how matter behaves in their intense gravity.
The black hole is at the center of a large galaxy known as NGC 3115, which is located about 32 million light years from Earth. A large amount of previous data has shown material falling toward and onto black holes, but none with this clear a signature of hot gas.
