This is the farthest radio signal humans have ever picked up

Searching for the secrets of the universe adds a new hero.

a Article published in Monthly Notices of the Royal Astronomical Society warns us of a radio signals previously detected Astronomers from Montreal and India. Normally, it is the galaxies close to our location that send this kind of signal, but in this case it seems to be coming to us from position further than usualWhat really makes it special. This is the main factor so that radio signals can teach us more about the universe around us.

Knowing the universe through really distant radio signals

Recently, there are many space telescopes, such as James Webb, which proves extremely useful for unraveling cosmic mysteries. However, this time it was Giant VHF Radio Telescope in India Which helped researchers discover Farthest wireless signal ever captured, with a very specific wavelength, which is 21 cm. Arnab Chakraborty, Research Fellow at McGill University, says Scitechdaily Medium which – which:

The galaxy emits different types of radio signals. Until now, it was only possible to pick up this particular signal in a nearby galaxy, which limited our knowledge to the closest galaxies to Earth. But thanks to the help of a natural phenomenon called gravitational lensing, we can pick up a weak signal at a record distance. This will help us understand the formation of galaxies at very great distances from Earth.

the galaxy Where this radio signal is called SDSSJ0826+5630 is a star-forming region in space. The researchers were able to measure the composition of the gas there, noting that its atomic mass is about twice that of the stars we can see. the The captured signal returns from when it was being it was just 4.9 billion years, which is best to be able to form a picture of its early stages. It would be, says Rabbit, “like looking 8,800 million years into the past.”

What helped truly Discovery From this reference is the concept we referred to earlier gravitational lens, through which a signal from any object in the universe is amplified and allows us to pick it up more clearly. In this case, as stated by Nirupam Roy, co-author of the study, “the signal magnification reaches a factor of 30, allowing the telescope to pick it up.” the researchers Is also Enthusiastic Through the possibilities that this gravitational lens can serve us Look much further into space and timeIn the not too distant future.
