Oldest Invisible Galaxy Discovered

We are all familiar with the galaxy images from Hubble or from James Webb. These images your light observed at different wavelengths and optical It consists of images of galaxies that can be perceived as Scientists have different tools to reveal the part that our eyes cannot see.

One of these tools is to study radio waves. It is even possible to position a galaxy according to the traces left around the fragments ejected by black holes. These galaxies are called radio galaxies. Known oldest radio galaxy was discovered recently.

Galaxy hidden among the ruins

located at the center of galaxies supermassive black holes it can explode from time to time and spread particles around. These thrown pieces continue on their way at very high speeds until they collide with something in space. It is possible to observe the traces they leave behind in the form of radio signals.

At the center of the Abell 980 galaxy cluster, scientists have discovered an extraordinary structure. in india Surajit Paul from Savitribai Phule Pune University Led by astronomers, they have unearthed the oldest radio galaxy ever discovered. Also located in India from Mumbai University astronomer Gopal Krishna and his team discovered two new radio galaxy clusters in the same region. In other words, the black hole in the center of the galaxy has performed large particle emission activities more than once.

The area covered by radio galaxies can reach millions of light years, from the galaxies in which they emerged They can reach much further. In fact, our galaxy, the Milky Way, has its own radio galaxy.

Because these radio signals fade over time, specimens older than 200 million years are not expected to be found. 2 billion light years This galaxy in the distance comes from 260 million years ago. Its distance is measured as 1.2 million light years. Scientists believe they can learn more about radio galaxies by studying this structure.
