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

MACS 0647-JD could be the most distant galaxy viewed so far during the human journey to the beginning of space and time

Hubble Views Most Distant Galaxy Ever

The first galaxies

Astronomy news (November 28, 2013) – The Hubble Space Telescope, along with the light magnifying ability of the effect called gravitational lensing, has provided the first views of the most distant galaxy seen during the human journey to the beginning of space and time. The astronomers of the Cluster Lensing and Supernova Survey with Hubble (CLASH) recently discovered three gravity-lensed images of a galaxy that existed over 13.7 billions years ago taken using Hubble’s new panchromatic imaging capabilities. Designated MACS 0647-JD, this ancient star city is currently the most distant galaxy located to date using the Hubble Space Telescope and gravitational lensing.

The CLASH program

The astronomers of CLASH used the Hubble Space Telescope to look at 25 distant galaxy clusters during the period from November 2010 to July 2013. They were looking for light which had been magnified due to the effect known as gravitational lensing as predicted by Einstein’s General Theory of Relativity. They wanted to detect additional Type Ia supernovae, map the distribution of dark matter in galaxy clusters, detect the most distant galaxies ever and study the internal structure and evolution of the galaxies in and behind these clusters.

The three gravity-lensed images taken by Hubble are of a small galaxy, now designated MACS 0647-JD, which could have been one of the first galaxies to exist in the universe. Astronomers’ analysis of the images suggests this small galaxy was less than 600 light-years across, which may indicate it was in the first stages of galaxy formation. In fact, this smaller galaxy may have been just one building block in the construction of a larger galaxy, and during the past 13.7 billions years could have been part of dozens, hundreds and even thousands of merging events with other galaxies.

Astronomers look at other possibilities

The astronomers of the Cluster Lensing and Supernova Survey with Hubble recently used the ability of NASA’s Spitzer Space Telescope to help rule out other possible identities of the three images they found. Next, astronomers will use the Spitzer Space Telescope, and other telescopes, to confirm the existence of the galaxy and try to get a better estimate of its age.

Astronomers hope to use the data they obtain from the study of galaxies like MACS 0647-JD to learn more about the early universe
Astronomers hope to use the James Webb Space Telescope to look even further back in time and space

Hubble Finds the The Biggest Black Hole

The nature of the beast

Astronomy news (November 26, 2013) – Astronomers believe the size of a black hole should be related to the size of the galaxy in which it resides, so the smaller a galaxy, the less massive its black hole should be. The lenticular galaxy NGC 1277 appears to have a black hole near its center with a mass out of proportion to its size, which indicates this theory will have to be looked at again.

NASA astronomers conducting a study of black holes at the Max Planck Institute for Astronomy recently used the Hubble Space Telescope and Hobby-Eberly Telescope in Fort Davis, Texas to measure the velocities of stars in orbit around NGC 1277. The higher the velocity of these stars, the greater the mass of the central object. NGC 1277 is located at a distance of around 250 million light-years, toward the constellation Perseus.

Astronomers measured the mass of the object at the center of NGC 1277 to be around 17 billion times the mass of the Sun, which is over four thousand times more massive than the 4 million solar mass black hole at the center of the Milky Way. Until recently, the two most massive central bodies found in any galaxy measured by astronomers reside in galaxies NGC 3842 and NGC 4889. This would make the central object in NGC 1277 the most massive found to date during the current study of black holes by NASA astronomers at the Max Planck Institute for Astronomy.

Astronomers measured the central mass in NGC 1277 to be over 4 times as massive as the one in our own Milky Way

NASA astronomers estimate the central mass in NGC 1277 has about 14 percent of the total mass of this smaller galaxy, which when compared to the expected 0.1 percent of the mass of the stellar bulge of the galaxy, could mean astronomers will have to rethink current astrophysical theories on galaxy-black hole systems.

What now?

NASA astronomers at the Max Planck Institute for Astronomy are currently going over the data obtained during their study of NGC 1277, to see if they can come up with a new theory on how the central mass could be so massive as compared to other galaxy-black hole systems studied.

Current ideas include the possibility the black hole at the center of NGC 1277 could have been ejected from nearby galaxy NGC 1275 and then subsequently captured. We’ll keep you updated as more information and data comes in on theories concerning galaxy-black hole systems during the continuing human journey to the beginning of space and time.
