A Radio Telescope Displays the Milky Way’s Center and Dead Stars


A Radio Telescope Displays the Milky Way’s Center and Dead Stars.

A perfect view of the center of the Milky Way was captured with a radio telescope in the west of Australia. If the human eye could read the radio waves, the telescope would capture the image of the Milky Way.

Muchison Wide Field Sequence (MWA) telescope, located in the west of Australia, has captured an important image of the center of the Milky Way. The astrophysicist Dr. Natasha Hurley-Walker of the Curtin University created the telescope’s radio waves using the Pawsey Supercomputing Center. Dr. Hurley-Walker said, yeni This new view provided low-frequency radio transmission from our galaxy, both in detail and looking at larger structures. Images, right from the center of the Milky Way, astronomers call the center of the galaxy from a region, “she said.

GLEAM published the data of the research on the images captured by the telescope. The telescope maps the space using radio waves at frequencies between 72 and 231MHz with a resolution of two arc minutes.

Ücü The power of this wide range of frequencies makes it possible to unravel objects covered when we look at the complexity of the galactic center, Hur says Hurley-Walker. Basically objects have different “radio colors.. That’s why we use these “radio colors bulmak to find out what kind of appearance it is.”

Using images captured by the MWA telescope, the researchers discovered the remains of 27 major stars. These stars were eight times larger than the Sun before they died.

Scientists say that it is easy to identify supernovae that have recently died, whose residues are nearby, or in a very dense environment. So far, 295 supernovae have been identified in this way. Unlike other telescopes, MWA can also find supernovas that are not in this way, in older, distant or dense environments.

The last supernova remnant MWA finds is thus located in a very young and very empty space far from the plane of the galaxy. Researchers said that the star died 9,000 years ago, and that this could be observed in Australia at the time.

Dr. Natasha Hurley-Walker explained that two of the discovered supernova remains were extraordinary. The two supernova remains were found in a space region without large stars. The two supernova remains discovered in the research are also quite old supernovae. Scientists say finding such ancient supernova remains is important evidence to look at the Milky Way’s past.

In Australia, the MWA telescope foreshadows the world’s largest radio telescope to be built in Australia and South Africa in 2021. With the Square Kilometer Array radio telescope to be built in 2021, the remnants of supernovas that have taken place in the last 100,000 years can be viewed with better resolution.
