Scientists suggest a more intelligent way to search for strange radio signals

The search for intelligence outside the planet (SETI) was not discovered after strange techniques such as radio waves, but the universe is vast, and there are many remaining places. New research indicates improvement of our search parameters using our broadcasting in the distant space as a useful guide.

research Published Earlier this week at Letters Astrophysical Journal Letters, we suggest that we look for strange signals by studying how we feel strong and directed during bilateral communication with our deep space duties.

The research team, which included scientists from the state of Pennsylvania and the NASA jet laboratory (JPL), has studied how foreign observers can discover deep space radio transfers. They highlighted that if they were engaged outside the planet in activities similar to space, their signs are likely to appear under the same circumstances, thus narrowing where and when we should look.

Seti has been inhaled radio signals outside the planet since the 1960s, but it has become empty so far. Part of the challenge is that we are not quite sure of what we are looking for, regardless of the original artificial thing.

This deliberate and focused sign may mean attracting our attention, or it may be unintended: the remaining transportation processes bleed from a civilization that revolves around its work. In fact, our private civilization was leaking radio signals for more than a century. We were not completely calm – our airports, for example, It is especially leaked When it comes to radio waves.

Finding patterns in our customs

In an attempt to improve our chances of discovering radio signals outside the planet, researchers, including the Penchen astronomer from Penchen, Pennsylvania, have investigated NASA’s deep space transfers as a way to predict how to use strange civilizations for the radio itself.

“Humans are mostly communicating with spacecraft and investigations that we sent to study other planets such as Mars,” Van explained in a statement. “But a planet like Mars does not prevent the entire transmission, and therefore the remote spacecraft or the planet placed along the path of these connections between the planets can discover anthropology; this may happen when the Earth and the planet of another solar system from its perspective.”

So we must focus on these types of the main moments, when external planets fall into the distant stars systems in alignment – this is when Seti should be looking for possible radio signals.

To study, the researchers analyzed the records from NASA Deep space network (DSN), a system of ground facilities that track and communicate with human things in space-from satellite in the orbit of low-Earth to remote missions such as Voyageer investigations and a new spacecraft. Joseph Lazio, the JPL project and the co -author of the study, explained that DSN “sends some of the most stable and stable radio signals in humanity to space.” By matching DSN radio broadcasting with data on spacecraft sites, the team enables the team to define both the timing and direction of deep -Earth space transfers.

“Using our deep connections to the basis area, we have estimated how future researchers can be improved for intelligence outside the planet by focusing on systems with specific directions and planet parallels,” said Jason Wright, a professor of astronomy and astronomical physics in Pennsylvania.

Look for alignment

The researchers have found that deep space radio signals are mostly aimed at Mars, but are also directed to other solar system planets and in telescopes placed in Lagrange Sun-Eart (James Web telescope is a good example). DSN data, which is worth two decades, has shown that if foreigners are in a position to monitor the alignment of the Earth’s wicked, there is an opportunity of 77 % that they will be in the way of our transport operations, compared to a 12 % opportunity to align the other planet. “When you don’t watch the alignment of the planet, however, these opportunities are minimal,” said Van.

The research team says we must apply these ideas to SETI, as it is likely to improve our chances of finding stray radio signals. Specifically, we must focus on the moments when external planets fall into compatibility with each other or with their host star, as it appears from our point of view on Earth.

Our solar system is relatively flat, as most planets revolve on the same plane, so most human transmission operations are transmitted along the same plane. Foreigners are likely to use similar communication strategies, so it makes sense for SETI to target the same types of alignment.

Given the strength of DSN and assuming that foreigners use similar communication technology, the authors participating in the study recommend research within 23 light years. More importantly, they say we must also focus on nearby tropical aircraft systems on the ground. They also notice that these patterns can help search for laser signals, which leak less than radio waves and may be preferred by strange civilizations; In fact, We are moving in this exact direction.

This new proposal makes a lot of meaning. We hope that SETI scientists take the observation of campaigns and take into account these ideas. The universe has the ability to be a very noisy place – we just have to know when and where to look.
