Nationalgeographic.co.id—Image telescope new revealed the presence of 1,000 strands of mysterious, hanging mysteriously in outer space. The findings are unprecedented from a turbulent galaxy Milky Way.
In the 1980s, Farhad Yusef-Zadeh of Northwestern University found the magnetic filaments very organized. Filament confusing, he found, consisting of the electron cosmic rays that rotates in a magnetic field close to the speed of light. But their origin remains an unsolved mystery since that time.
The filament is stretched up to 150 light years. Strands of one-dimensional (or filaments) are found in pairs and groups, often stacked with the same distance, side by side like the strings on a harp.
Now, new observations have revealed the presence of filaments 10 times more than that found previously. It allows Yusef-Zadeh and his team to conduct a statistical study on the whole population of the filament area for the first time.
This information could potentially help them to finally uncover the mystery of the old. Details of the study published in The Astrophysical Journal Letters not long ago with the title “Statistical Properties of the Population of the Galactic Center Filaments: the Spectral Index and Equipartition Magnetic Field“.
Yusef-Zadeh, lead author of the paper says it has learned each of the filament for a long time with imaging, which is not so good. Yusef-Zadeh is professor of physics and astronomy Northwestern’s Weinberg College of Arts and Sciences.
“Now, we finally see the big picture — panoramic views filled with filaments are abundant. Just check out some of the filament makes it difficult to draw real conclusions about what it is and where it came from. This is a turning point in advancing our understanding of this structure,” said Zadeh as reported by space.com.

The image is believed to be scientists may be a pulsar issued by the events of a supernova.

To get images with clarity and detail that is unprecedented, astronomers have spent three years to observe the sky and analyzing data in the South African Radio Astronomy Observatory (SARAO). With observations over 200 hours using a telescope MeerKAT SARAO, the researchers collected 20 of the mosaic observations apart from the different sky toward the center of the Milky way, the 25,000 light years from the Earth.
Image details will be published in the papers additional accompanying, led by astrophysicist, University of Oxford Ian Heywood and co-authored by Yusef-Zadeh in the upcoming edition of The Astrophysical Journal. Along with the filament, the image capturing radio emissions of various phenomena, including the explosion of a star, a stellar nursery and the rest-the rest of the supernova new.
