Galaxy SDP.81 Forms Stars at Enormous Rate

With the help of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have been able to capture an image of a galaxy named SDP. 81. From the images, astronomers were able to know new details of the galaxy present near the end of the universe.

Astronomers said that the galaxy is forming stars at a rate that is hundreds to thousands times faster in comparison to Milky Way. The galaxy is present 11.7 billion light years away from earth and is located in Hydra constellation.

Also, researchers from University of Tokyo along with other researchers from National Astronomical Observatory of Japan (NAOJ) have created a gravitational lens. The model has found that the galaxy SDP. 81 has been forming stars at quite a fast rate than the Milky Way.

The researchers termed the new galaxy to be a case of an Einstein ring. They affirmed that it is one of the rarest cases in which a distant galaxy and earth lines up perfectly. The image looks like a circle of light known as Einstein ring.

As per Einstein's theory of General Relativity, a massive object bends time and space. Clouds have also been spotted in SDP. 81. Astronomers said the clouds spotted in the galaxy are of the same size as that of other galaxies.

It is the first time that researchers have been able to understand and reveal the inner structure of a galaxy. "The reconstructed ALMA image of the galaxy is spectacular. ALMA's huge collecting area, the large separation of its antennas, and the stable atmosphere above the Atacama Desert all lead to exquisite detail in both images and spectra", said Rob Ivison, European Southern Observatory's Director for Science.
