In certain conditions, the image of the galaxy with its center will seem impressive resemble various forms. Such images shared NASA this time, looks like a sighting of the sky eye in outer space.
As quoted from the WIO News, Wednesday (6/10/2021) of galaxies have a supermassive black hole at its center. The core of the galaxy emits large amounts of electromagnetic radiation.
The galaxy was named Seyfert, or in scientific circles identified as NGC 5728. Galaxies Seyfert look like the galaxy in general, but have a core of active galaxy that has a high luminosity out of the ordinary.
Additional information mention, this galaxy belongs to a class of galaxies known as a source of electromagnetic radiation most radiant. As for the images shared by NASA is perpetuated by the Hubble Space telescope.
Luminosity galaxies Seyfert is 10^8 to 10^11 times the Sun’s luminosity. Image of the stunning galaxy captured by the Wide Field Camera 3 (WFC3) of the Hubble.
This is not the first time found a galaxy with forms such as eyes. The previous was already there ever was a similar form, even assortment. Nothing resembling the face of a ghost, pretty butterfly, cat eye, and much more.
Scientists Found a Hole in Space, It is not Yet Known
Scientists found a hole in between the stars that are in space. He lies about 700 light-years away in between the constellations Perseus and Taurus.
Scientists discovered the hole in between the stars that are in space. Located about 700 light-years, it is located between the constellations of Perseus and Taurus.
Astronomers have found a vacuum ball-shaped with diameter of more than 500 light-years. Around him there are molecular cloud Perseus and Taurus – a dense cloud of cold gas and dust where stars are formed.
This thing is called Per-Tau Shell, and apparently is the result from the supernova explosion of a giant millions of years ago. The possibility of this phenomenon pressing and trigger the formation of stars in the two molecular cloud.
“Hundreds of stars is being formed or existing on the surface of a giant bubble,” said astrophysicist theoretical Shmuel Bialy from the Harvard-Smithsonian Center for Astrophysics (CfA).
“We have two theories – one of the supernova exploded in the core of the bubble and push the gas out to form what we now call the ‘Super Skin Perseus-Taurus’, or a series of supernova that occurs over millions of years was the one that created it,” he continued.
To find the need to eat energy, but scientists still continue to wonder. Indeed as deep as what this empty space?
To explore the molecular cloud Perseus and Taurus, the researchers used data from the Gaia observatory, a satellite of the European Space Agency, which has been working since 2013 to map the Milky way in three dimensions with the most detail and the highest precision that can be achieved. This is one of the most cutting-edge that we have.
Data were analyzed using the visualization software called the glue, which allows scientists to make interactive 3D visualization. From here, astronomers can build a 3D map of the gas in molecular clouds and other.
“We have seen this cloud for a few decades, but we never know the shape, depth, or thickness of the truth. We are also not sure how the cloud,” said astronomer Catherine Zucker also of the Harvard-Smithsonian CfA.
According to the analysis team Bialy, a void that almost ball-shaped probability is the result of a supernova explosion that strong. This explosion sent shock waves in all directions into interstellar space. When the shock wave expands, it pushes and compresses the material in the interstellar medium, sweep to the top so as to form the shell of the round.
But there is another theory, that it is a process of formation of new stars. Star formation is expected to occur when the region that is dense in the molecular cloud collapse, spin, under its own gravity. When the shock wave from the supernova extends into the space around it, he can sweep gas in the interstellar medium to form a molecular cloud with solid areas and then start forming stars.
This is what according to the team going with Per-Tau Shell. Between 6 and 22 million years ago, from the reconstruction of the scientists show that the events of the supernova creates a cavity in the interstellar medium. This is also the one who creates the shell and the molecular cloud Perseus and Taurus. At this time, the bubble is also not seen widespread again, in other words still intangible the same.
“This shows that when a star dies, supernovanya produce the series of events that can ultimately lead to the birth of new stars,” said Bialy.
Interactive 3D models of shells Per-Tau can discover on the web site of Harvard. This paper has been published in ‘The Astrophysical Journal Letters’, as reported Science Alert.
