New Galaxy Image Sets from ATEO-3

Insight Observatory's affiliate remote telescope, the 12.5" f/9 Ritchey Chretien (ATEO-3) located at Deep Sky Chile has been very busy as of late producing additional image sets for Starbase. The latest additions to Starbase from ATEO-3 are image sets of Messier 83, the "Southern Pinwheel Galaxy", and NGC 1313, also known as the "Topsy Turvy Galaxy".

Messier 83 - the Southern Pinwheel Galaxy imaged on ATEO-3 and processed by Franck Jobard from Deep Sky Chile, now available for download from Starbase.

Messier 83 or M83, also known as NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas Louis de Lacaille discovered M83 on February 23, 1752, at the Cape of Good. Charles Messier added it to his catalog of nebulous objects (now known as the Messier Catalogue) in March 1781. It is one of the closest and brightest barred spiral galaxies in the sky and is visible with binoculars. Its nickname the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy (M101) in the northern constellation Ursa Major.

Starbase image set "M83 - Lum (2021): Southern Pinwheel Galaxy" has over 10 hours of Luminance image data and set "M83 - RGB (2021): Southern Pinwheel Galaxy" consists of 3 hours each of Red, Green, and Blue image data. 

Image Set Rates:

• M83 - Lum (2021): Southern Pinwheel Galaxy is only $24.40 USD for Education and $30.50 USD for Standard. 


• M83 - RGB (2021): Southern Pinwheel Galaxy is only $21.60 USD for Education and $27.00 USD for Standard.

NGC 1313 - the Topsy Turvy Galaxy imaged on ATEO-3 by Franck Jobard and processed by Utkarsh Mishra from Deep Sky Chile is now available for download from Starbase.

NGC 1313 is a field galaxy and a barred spiral galaxy discovered by the Scottish astronomer James Dunlop on 27 September 1826. It has a diameter of about 50,000 light-years or about half the size of the Milky Way. NGC 1313 lies within the Virgo Supercluster. NGC 1313 has a strikingly uneven shape and its axis of rotation is not exactly in its center. The galaxy also shows strong starburst activity and associated super-shells. NGC 1313 is dominated by scattered patches of intense star formation, which gives the galaxy a rather ragged appearance. The uneven shape, the ragged appearance, and the strong starburst can all be explained by a galactic collision in the past. However, NGC 1313 seems to be an isolated galaxy and has no direct neighbors. Therefore, it is not clear whether it has swallowed a small companion in its past.

Vela Nebula Image Sets from ATEO-3

There are new image sets available in Starbase, Insight Observatory's image set repository. These sets consist of combinations of H-Alpha, Oxygen III, and Red, Green, and Blue filtered image data of a section of the Vela Nebula (supernova remnant) located in the southern constellation of Vela. These image sets were acquired by Franck Jobard on Insight Observatory's 12.5" f/9 Ritchey-Chretien affiliate remote telescope ATEO-3 hosted at Deep Sky Chile.

The Vela supernova remnant's source Type II supernova exploded approximately 11,000 to 12,300 years ago. The association of the Vela supernova remnant with the Vela pulsar, made by astronomers at the University of Sydney in 1968, was direct observational evidence that supernovae form neutron stars.

An HaRGB section of the Vela Nebula supernova remnant acquired and processed by Franck Jobard on Insight Observatory's 12.5" f/9 Ritchey-Chretien affiliate remote telescope located at Deep Sky Chile.

This supernova remnant includes NGC 2736. It also overlaps the Puppis A supernova remnant, which is four times more distant. Both the Puppis and Vela remnants are among the largest and brightest features in the X-ray sky.

The Vela supernova remnant (SNR) is one of the closest known to us. The Geminga pulsar is closer (and also resulted from a supernova), and in 1998 another near-Earth supernova remnant was discovered, RX J0852.0-4622, which from our point of view appears to be contained in the southeastern part of the Vela remnant. One estimate of its distance puts it only 200 parsecs away (about 650 ly), closer than the Vela remnant, and, surprisingly, it seems to have exploded much more recently, in the last thousand years, because it is still radiating gamma rays from the decay of titanium-44. This remnant was not seen earlier because, in most wavelengths, it is lost because of the presence of the Vela remnant.

The Moon is the biggest single object in the night sky that’s visible to the eye alone. But many objects that are too faint to see are much bigger. The nebula spans about 16 times the width of the Moon, almost the size of your fist held at arm’s length and it’s getting bigger all the time.

When the supergiant star exploded, blasting its outer layers into space, those layers rammed into surrounding clouds of gas and dust, causing them to glow. If you look across the entire spectrum - from radio waves to X-rays - the nebula looks like a mound of billowing clouds.

When the star exploded, the outer layers were expelled at up to a few percent of the speed of light. So over the millennia, the nebula has inflated to a diameter of more than a hundred light-years. And it’s still expanding - at more than two million miles per hour.
