One of the first constellations in the night sky to be perceived the human eyes, Aquarius the Water Bearer was first recorded by Babylonian astronomers as “the Great One” on stones and official seals as early as the year 2000 BCE.

Located in the fourth quadrant between latitude 65-90, Aquarius the Water Bearer is the 10th largest constellation covering 980 square degrees of the night sky.

Between the Great Square of Pegasus and the Bandanna of Capricornus lies the rather nondescript constellation of Aquarius the Water Bearer.

Found near Cetus (the whale), Pisces (the fish), Delphinus (the dolphin) and Eridanus (the river) on the Sea of the Southern sky, Aquarius the Water Bearer is best viewed in the evening sky in the Southern Hemisphere in spring and autumn in the Northern Hemisphere.

Look high in the Northern or Southern Hemisphere sky early in October around 10 p.m. local time (11 p.m. local daylight saving time), or early in November around 8 p.m. local time, to best see Aquarius the Water Bearer.

Astronomers View Rectangular Galaxy Never Seen Before

Astronomers studying galaxies have discovered something unusual

Astronomy news (November 29, 2013) – Astronomers have found galaxies of different shapes and sizes during the human journey to the beginning of space and time, but the rectangular-shaped galaxy astronomers recently located 68 million light-years away in Eridanus the River doesn’t fit any current theory of what a galaxy should look like. Leda 074886 is one of about 250 galaxies in the cluster of galaxies around the massive galaxy NGC 1407, which lies about 70 million light-years from Earth in the constellation Eridanus.

Astronomers wonder about this rectangular shape

Astronomers detected LEDA 074886 in a wide-field image taken with the Japanese Subaru Telescope. After analysis astronomers detected a stellar disk inside the rectangular-galaxy, aligned edge-on to our line of sight in the Milky Way. This disk is rotating at speeds up to 33 km/second, but at this point they’re not sure it has a spiral structure characteristic of a galaxy.

Astronomers classify galaxies according to their overall shape, using three general categories; elliptical, disk-like, and irregular. The unusual shape of the galaxy designated LEDA 074886 doesn’t fit into any of these three categories. The question astronomers are asking is how did this galaxy come to have this unusual shape?

Could this rectangular shaped galaxy be the result of a galactic collision?

Is the unusual shape of this galaxy due to a collision with another galaxy, perhaps between two spiral galaxies? Astronomers models indicate this scenario could possibly result in the stars of each galaxy flinging outward to form a rectangular shape. Astronomers also detected a disk of bluish, relatively young stars near the center of this galaxy, which they believe could indicate a recent collision with another small galaxy. This discovery should help astronomers model the formation and evolution of galaxies better and perhaps get a picture of the fated collision between the Milky Way and Andromeda 4 billion years from now.

Astronomers are wondering if LEDA 07886 is how our galaxy and Andromeda will look when they collide four billion years from now
