"A SPIRAL GALAXY IN FORNAX"
- Deepsky 2857mm LRGB
- Area Constellation Fornax

NGC 1365 is a barred spiral galaxy of Hubble type SBb in the constellation Fornax in the southern starry sky. The shape of the bars is striking and it is one of the best-known barred spiral galaxies. The galaxy is around 68 million light years away and has a diameter of over 200,000 light years. NGC 1365 is a type 2 Seyfert galaxy and belongs to the Fornax galaxy cluster. Seen from Earth, it rotates clockwise; a complete rotation takes around 350 million years.
Astronomers are particularly interested in the complex movement of interstellar matter in the galaxy and how it influences the gas supplies from which new stars are formed. The enormous bar causes disturbances in the gravitational field of the galaxy, which compress gas in certain areas and thus stimulate star formation. Countless young star clusters can be seen in the spiral arms, each containing hundreds or thousands of young and bright stars, all of which have formed within the last ten million years.
As is common with spiral galaxies, the center of NGC 1365 is a supermassive black hole (SMBH). By a lucky coincidence (a gas cloud slipped into the line of sight between the Earth and the center of the galaxy), the gas disk emitting X-rays around the black hole was recently measured using the Chandra X-ray telescope stationed in space. According to the measurement, the gas disk has a diameter of 7 AU, which corresponds to only ten times the calculated event horizon. Four supernovae have been observed in NGC 1365 so far: SN 1957C (type unknown), SN 1983V (type Ic), SN 2001du (type II-P) and SN 2012fr (type Ia).
The object was discovered on November 24, 1826 by the Scottish astronomer James Dunlop.
