NASA’s Hubble Space Telescope Shed New Light on How Dead Galaxies Evolve

NASA’s Hubble Space Telescope, which operates in low Earth orbit since 1990, added a new pen to its cap by detecting the first dead galaxy of its nature that could change the way it understands the concept of how dead galaxies evolve.

Topics such as galaxy formation, composition, and especially “dead” galaxies remain an enigmatic source for astronomers, and despite advances in space technology, the full disclosure of these mysteries has not been possible.

But the latest discovery by NASA and the ESA Hubble Space Telescope seems to change the scenario.
The latest article, published in the journal Nature, an international team of astronomers from the University of Copenhagen, Denmark found a single galaxy and is compressed, but supermassive, rotating rapidly in disk form whose ability to make stars left a few billion Years after the Big Bang event.

According to astronomers, detecting a galaxy such that it belongs to the first period of the universe can challenge the current concept of galaxy size and its configured evolution.

The team of scientists led by Sune Toft by the University of Copenhagen has drawn the discovery of the galaxy by analyzing the reports and information captured by a NASA space telescopes of the most powerful Hubble.

Gradually, as scientists point out, astronomers were supposed to find the first dead galaxy photographed as a disorganized sphere of stars, configured galaxies blending together. But instead, they came across a reliable indication that showed how the stars were motionless in a disk-shaped cake.

The discovery, made by the Hubble Space Telescope, is the first evidence of direct observation that revealed certain galaxies called “dead” more primitive, where the formation of the star stopped.
As researchers point out, these dead galaxies are the Milky Way region similar to the giant egg-shaped galaxies we see used today.

As highlighted in the new study paper, remote galaxy is still three times larger than the Galaxy military, Earth, but it is only half the size.

Speed measurements using the European Southern Observatory’s Very Large Telescope (VLT) revealed that the galaxy’s disk is changing more than twice as fast as our Milky Way.

Toft and his team used archive data collected from the survey, Lensing Cluster and Supernova together with Hubble (CLASH), to determine planetary mass, star formation rate and star age.

So far, the reason that forced the galaxy to stop star formation is not identified. However, researchers believe that this may be the dynamic galactic nucleus, in the push pushes forward of a super massive black hole caused this galaxy to stop the formation of dead tar.
