Using an independent sample of brightest galaxies in rich clusters in the southern galactic hemisphere, we confirm the Argyres et al. A small group of faint galaxies huddle around a 7th magnitude star to the southwest of NGC 5128. Here is a view of the night sky for December 2020. 100 Brightest Galaxies for Southern Observers Submitted: Friday, 13th January 2006 by Paul Mayo Common lists of Astronomical Objects have historically been compiled by Astronomy pioneers and more recently by institutes like the Space Science Telescope Institute (STScI) who compiled the first Guide Star Catalogue to meet the operational needs of the Hubble Space Telescope. Now a new Guide Star Catalogue, GSC-2, is in production and the catalogue already contains data for more than 450-Million Stars and Non-Stellar Objects. No need for a telescope — the galaxies are so close that they appear much bigger than anything else visible from Earth. 12" (300m) telescope = 15
With only 12 percent of the world’s population living south of the Equator, the jewels in the southern night sky can stay half-secret. Even though the Southern Cross is well known to people all over the world, not many know how to find it in the sky. The Magellanic Clouds (or Nubeculae Magellani) are two irregular dwarf galaxies visible in the Southern Celestial Hemisphere; they are members of the Local Group and are orbiting the Milky Way galaxy.Because both show signs of a bar structure, they are often reclassified as Magellanic spiral galaxies. Because they are on opposite sides of the southern circumpolar sky, when one is low near the horizon, the other is at its highest point. To find Achernar it is easiest to imagine a line extending through the long axis of the Southern Cross. Its stars decrease in brightness in a clockwise direction starting at its brightest star Acrux which is the bottom star in the long arm of the cross and lies at a distance of 360 light years. Counted amongst the riches that belong to the southern celestial sphere are an astonishing array of beautiful deep-sky objects, including the naked-eye galaxies known as the Small and Large Magellanic Clouds; the globular clusters 47 Tucanae and Omega Centauri; the Helix Nebula and Coalsack Nebula; and the Jewel Box open cluster; to name but a few. Or How many Galaxies, in the Southern Sky, are larger than 10 arc minutes and brighter than Magnitude 10 ? Though quite literally outshone by its neighbor, the bright star sitting just by Alpha … Galactic delights include Centaurus A (NGC 5128), the fifth-brightest galaxy crossed by a distinctive dust lane, and the Great Rift in the Milky Way, a dark lane that divides the Milky Way’s bright band lengthwise. Astronomers have mapped about a million previously undiscovered galaxies beyond the Milky Way, in the most detailed survey of the southern sky ever carried out using radio waves. Triangulum Galaxy with a diameter of 50,000 light years stands as the fourth brightest galaxy observed from the earth. The Southern Cross (Crux) is the smallest of the 88 constellations and probably the most recognized by Southern Hemisphere dwellers. In addition to permanent constellations, the southern hemisphere hosts rare astronomical events, such as total solar eclipses. The brightest star in Sculptor is Alpha Sculptoris and is located about 13.70 light years from the Sun. I have personally observed the 2 brightest northern hemisphere galaxies from a dark sky location (Bortle Scale class 2). Or which are the 50 Brightest Planetary Nebulae in Southern Skies? The second-brightest (Beta 1 Sco) is Graffias. It is the shiniest among the top ten brightest galaxies in universe as seen from the earth. The LEDA database, created by G. Paturel from the de Lyon Observatory in France, collates data from all other known Galaxy Catalogues into one single database, such that LEDA contains many well known constituent astronomical catalogues that include Messier, NGC, IC, ESO, MCG and more than thirty others. At a distance of 170,000 light years away from the earth, Large Magellanic is only a satellite galaxy of our own Milky Way at size of about one tenth of the our galaxy. It consists of four bright stars forming the well known cross shape and a fifth star which appears as a "misplaced central star". M31 (right) is the nearest major galaxy to the Milky Way; 2.5 million light years away, which makes it … Small telescope: faint, round, 30 arcseconds see two galaxies with your naked eye expressed arc.
