Scientists and fans have debated for decades if the Humanity should or may not send messages in search of contact with aliens. After all, what if the recipients are hostile? But one New research suggests that this discussion is obsolete. This is due to the fact that in the last 75 years we have already published signs that reveal our presence on Earth.
Our Radar systems, both civil and military, already emit powerful signs that can be detected by possible foreign listeners,, a study presented by the Royal Astronomical Society.
The team, led by Ramiro Saide, of the University of Manchester, Simulated airport transmissions and military systems. And analyzed how these signs would be perceived from six stars nearby: Barnard Star, HD 48948, HD 40307, AU Microscopii, HD 216520 and LHS 475.
When it comes to high -power directional radar signs, the The Earth “shouts” from the first years of the Cold WarIn the 1950’s.
According to the study, the Signs of Civil Radar Combined on our planet add up to 2 × 10¹⁶ watts. And the Military systems add more focused and directional signs of about 1 × 10¹⁴ watts. All this generates a radio signature that denounces artificial technology.
With this intensity of emission, Any civilization located up to 200 light -light years and equipped with a radiotlenescope could detect us.
Previous studies, with more powerful telescopes, indicate that this Arriving can reach more than 60 thousand light years. That means that Our cosmic “visibility” is greater than you can imagine.
Research suggests that unintentional signs, such as those used in aviation and defense, function as universal markers of smart life.
Given that, the The real question now is if there is someone who receives our signs. And if it exists, how will this contact interpret: with curiosity, friendship or hostility?
The answer is still a mystery. But the Earth has definitely left its mark on the cosmos.

The video shows the interstellar visitor who goes through the solar system
One A new object interstellar, the Comet W/2025 N1 (Atlas) was detected, crossing the solar system. He is the The third visitor of this type already registeredTherefore, he also received designation 3i/Atlas.
The clearest images of the comet were made by a very large (VLT) telescope in Chile. According to the southern European Observatory (ESO), these Pictures represent the deepest record that has made an object that comes from outside the solar system.
The comet was discovered on July 1, 2025 by a Telescope of the Atlas project, also located in Chile and funded by NASA. It was then about 670 million km from the Sun.
Its highly elongated and open orbit has confirmed its interstellar origin. It is currently within the orbit of Jupiter. But in a position opposite to the Sun, far from the direct gravitational influence of the planet.
