The legendary "Wow!" radio sign from area, recorded virtually 50 years in the past, turned out to be considerably stronger. A brand new evaluation of knowledge from the "Large Ear" telescope confirmed a peak sign density of over 250 Janskys and refined its frequency.
The legendary radio sign from deep area, recorded virtually 50 years in the past, turned out to be considerably stronger than beforehand thought. A brand new digital evaluation of 75,000 pages of archived information from the "Large Ear" telescope allowed scientists to recalculate the depth of the burst and refine its traits. That is reported by Indian Protection Overview, writes UNN.
Particulars
A analysis crew led by Abel Mendez from the College of Puerto Rico carried out monumental work to digitize the 1977 paper printouts. Due to trendy computational strategies, it was established that the height sign density exceeded 250 Jansky. This makes it one of the vital highly effective narrowband bursts ever recorded inside the hydrogen line (1420 MHz).

The up to date evaluation additionally refined the sign frequency to 1420.726 MHz. This virtually completely matches the hydrogen line, which astronomers have lengthy thought of the most definitely channel for interstellar communication on account of its universality within the Universe.
The origin of the sign stays a thriller
Regardless of narrowing down the possible coordinates of the supply within the constellation Sagittarius, scientists nonetheless can’t clarify the character of the sign. The research confirmed that "Wow!" had an ideal Gaussian profile, which is attribute of a sign from a distant cosmic supply, and never of random terrestrial noise or interference from satellites.

Scientists dominated out the potential of radio wave reflection from the Moon or unintentional {hardware} failures. The sign lasted 72 seconds and by no means recurred. The preservation of the unique printouts by volunteers for many years allowed science in 2026 to revisit the query: was this burst the primary recorded message from an extraterrestrial civilization.
