Life is all about perspective. Since the earliest days of the human species, space has always existed as an enigma. In modernity, it's still something of an enigma, but only less so. Instead of stars and the infinite void surrounding them serving as a curious backdrop to our evening affairs, we have a pretty decent comprehension of what's happening in space. However, in a couple of centuries—if our species makes it that far—our knowledge of the universe will seem as meager as our ancestors'.
Whether we like it or not, we're in the transitional era of human space exploration. We have the means to attain astounding data about the cosmos, but none of us will likely get to witness the vast wonders we're discovering. According to The Economic Times, a radio signal from 9 billion light years away has been captured for the first time in human history.
For the first time, a radio signal sent from a galaxy, which is almost 9 billion light-years away from the Earth, has been captured, media reports said on Friday.
What is special about this signal is that it has a unique wavelength, which is known as a "21-centimeter line" or the "hydrogen line." It is reportedly emitted by neutral hydrogen atoms.
The signal was emitted from a "star-forming galaxy", which is titled SDSSJ0826+5630. It was emitted when the 13.8 billion-year-old Milky Way, where Earth is located, was just 4.9 billion years old, it said citing the researchers.
