NGC 3115 Galaxy in Sextans

Also known as Caldwell 53,this lenticular (S0)-Galaxy in the constellaiton of Sextans normally is listed as NGC3115.

Its a huge galaxy with a mass several times that of our own milky-way.At a distance of about 22mio light-years its apparent size is 7,2′ × 3,2′ with a brightness of 9.3mag.

Because of its edged-on presentation,there hardly can be detected any spiral structure of this galaxy.

A huge billion-solar-mass black-hole inside was examined by the CHADRA X-ray Observatory.You can read more about this with help of link down at this page.

Very little star-formation happens inside NGC3115:there is nearly no dust and gas left over for triggering such events.

NGC3115 was first seen by William Herschel in 1787.
