In discovering the existence of an intelligent life beyond the world, the first question we may ask is “How do we communicate?” As we approach the 50th anniversary of the 1974 Arecibo message — the first attempt by people to send a miss that can be understood by outside intelligence — the question is more urgent than any other. time. Advances in remote sensing technology have shown that many stars in our galaxy host planets and that many of these exoplanets appear to be able to host liquid water on their surfaces — a prerequisites for life as we know it. The complexity of at least one of these billions of planets having an intelligent life seems good enough to take a moment to think about how to say “hello.”
In early March, an international team of researchers led by Jonathan Jiang of NASA’s Jet Propulsion Laboratory posted a paper on the preprint server arXiv.org describing a new design for a message intended for foreign recipients. The 13-page book, dubbed “Beacon in the Galaxy,” is a keynote in mathematics, chemistry and biology that is strongly linked to Arecibo’s message design and other past efforts to connect strangers. The researchers included a detailed plan for the best time of the year to spread the message and revealed a thick ring of stars near the center of our galaxy as a successful outcome. Importantly, the ad also features a new return address to help any foreign audience locate our destination. position in the galaxy in order to — hopefully — start a visual conversation.
“The motivation for the design is to provide a high amount of information about our society and ethnicity with less message,” Jiang said. “With the advancement of technology, it could be much more efficient than the [Arecibo message] of 1974.”

Any visual message must answer two basic questions: what to say and how to do it. Almost every message spread by humans in space starts with the establishment of common sense and a basic lesson in science and math, two topics with which we are often familiar with strangers. If a nation beyond our planet could build a radio to receive our message, it might know a thing or two about physics. An even worse question is how to use these ideas in advertising. Human language is not questioned for obvious reasons, but so is our mathematical system. Although the concept of numbers is almost universal, the way we present them as numbers is very relevant. That’s why many businesses, including “Beacon in the Galaxy,” choose to design their books as a bitmap, a way to use binary code to create a pixelated image.
The philosophy of bitmap design for visual communication goes back to Arecibo’s message. An approximation — the on/off, present/less nature of a binary is likely to be recognized by any type of intelligence. But the plan always has its flaws. In the pioneering search for extraterrestrial intelligence (SETI) scientist Frank Drake designed a model of the Arecibo message, which he sent the binary message by mail to several partners, including several Nobel laureates. See the article : Quality RF Harmonic Balance Analyzes For Analog Analysis. None of them were able to understand what it was, and only one knew that the binary was meant to be a bitmap. If some of the most intelligent people struggle to understand this type of signaling as a message, it does not seem to be much more successful as a stranger. Also, it is not clear that outsiders will be able to see the images that contain the message when they receive it.
“One of the main ideas is that, since viewing has happened independently many times around the world, it means aliens will also be available,” Douglas Vakoch said. , president of METI (Messaging Extraterrestrial Intelligence) International, a non -profit organization dedicated to finding out how to do it. associated with other lifestyles. “But it’s a big ‘if,’ and even if they can see it, there’s a lot of culture that is embedded in the way we represent objects. Does that mean we have to put aside images? It’s really No. That means we shouldn’t foolishly assume that our information will be understood. ”
In 2017 Vakoch and his partners sent the first scientific data release message since 2003 to a nearby star. Also, it was labeled in binary, but it avoided bitmaps for a series of messages that analyzed the concepts of time and radio waves by means of returning to the radio wave carrying the message. Jiang and his friends chose another path. They based most of their designs on the 2003 Cosmic Call broadcast from the Yevpatoriaradio telescope in Ukraine. This message features a traditional “alphabet” created by physicians Yvan Dutil and Stéphane Dumas as a provincial language designed to be strong against mistakes.
After the initial pronunciation of a first number to mark the message as a specific object, Jiang’s message uses the external alphabet to identify our base-10 numbers and base numbers. With this basic principle, the message uses the spin-flip transition of a hydrogen atom to define the concept of time and mark the time when the radiation was sent from Earth, introducing common elements from the Earth. time table, and shows the structure and chemistry of DNA. . The final pages may be more interesting on the outside but even more confusing because they think the receiver is comparing things the same way people do. The following pages show a picture of a woman and a human being, a map of the world, a picture of our solar system, the radio that strangers should use to respond to the message. and coordination of our solar system to the galaxy in question. the location of globular clusters — the fixed and enduring parts of a thousand stars that seem to be familiar to a stranger anywhere in the galaxy.
“We know the location of more than 50 globular clusters,” Jiang said. “If there’s a progressive person, we say, if they know astrophysics, they also know where the globular cluster is, so we can use this as a coordinator to prove it. the place of our sun. “
To Send or Not?
Jiang and his friends say they send their messages from the Allen Telescope Array in northern California or the Five-Hundred-Meter Aperture Spherical Radio Telescope (FAST) in China. Since the recent demise of the Arecibo telescope in Puerto Rico, these two radios are the only ones in the world that are actively working on SETI researchers. Now, however, the two things can be heard in space, but not talked about. On the same subject : Organic semiconductors come to the 5G circuit. Jiang points out that wearing any vision and equipment needed to spread the message is not a trivial matter. But doing so is possible, and he said he is continuing discussions with researchers at FAST about implementation.
If Jiang and his colleagues get a chance to deliver their message, they thought it best to do so sometime in March or October, when the world is at a 90-degree angle between the sun and its focus on the center of the Milky. Road. This will increase the chances of missing the missile in the noise behind our host star. But it is a deeper question of whether we should send a message.
Foreign messages have always occupied a controversial position in the general public of SETI, which has largely focused on listening to broadcasts from out rather than throwing ourselves away. To the fans of the “strong SETI,” the system is a waste of time at best and a risky bet at worst. There are billions of goals to choose from, and the difficulty we have in sending a message to the right planet at the right time is extremely low. Also, we don’t know who might be listening. But what if we gave our address to an exotic animal that lives on a diet of bipedal hominins?
“I don’t live in fear of an attack of people, but other people do. And because I don’t share their fear it doesn’t matter what their concerns are,” Sheri Wells-Jensen said. , is an assistant professor of English at Bowling Green State University and is an expert in language and cultural subjects related to interpersonal communication. “Just because it’s going to be hard to reach a global agreement on what to throw or we should throw doesn’t mean we shouldn’t. It’s our responsibility to fight this and involve a lot. people who can. ”
Despite the setbacks, many argue that the potential rewards from a strong SETI outweigh the risks. The first contact is one of the most important moments in the history of our tribe, the debate goes on, and if we wait for someone to call us, it may never happen. As for the risk of an alien destroying the universe: We were blown away by our tragedy in the past. Any celestial being that can travel around the world will be more than able to detect evidence of life in the chemical signatures of our atmosphere or the electric heater that flowed. from our radio, television and radar systems for the last century. “This is an invitation to everyone in the world to join a conversation about sending this message,” Jiang said. “We hope, by publishing this paper, we can encourage people to think about this.”

Why do scientists need space telescopes?
The main reason we put telescopes in space is to move around the Earth’s atmosphere so that we can get a clear view of the planets, stars, and galaxies we are studying. Our environment acts like a protective blanket that only a little light passes through while others are obscured.
Of what use is the universe worth more than the things on earth *? Space has a greater chance of being exposed to the cloudy effects of the Earth’s atmosphere. In addition, many waves from the electromagnetic spectrum do not reach the Earth because they are absorbed or reflected by the Earth’s air.
What are three advantages to space telescopes?
Good condition. It is possible to make clear statements because they do not harm the air. There are no disturbances due to lightning, sunlight or the effects of light damage. Many waves of electromagnetic radiation such as infrared, ultraviolet, x-ray and gamma rays can be observed.
What are some advantages of space telescopes over telescopes on Earth?
Observations such as Hubble have a much clearer view of the universe than most of them on the ground. They can also study radio spectrum and wavelengths throughout the electricity spectrum.
What are two key advantages of space telescopes?
The Hubble telescope offers four main benefits over many other space -specific objects: modeling on a vast terrain, dramatic displays from near infrared to far ultraviolet, a vast dark sky, and stable images that enable accurate photometry.
What advantages do space telescopes have over Earth based telescopes quizlet?
What benefits do airplanes have over the world? Astronomy revolves above the Earth’s atmosphere and produces much clearer images than basic visions on Earth.
What is not an advantage of space telescopes over ground-based telescopes?
Which of the following is not a benefit of the Hubble Space Telescope rather than the use of the earth? It is close to the stars. Which of the following wavelengths cannot be studied visually on the ground? Telescopes operating on this long wave must be sufficient to monitor space.
What are the advantages of placing telescopes in space quizlet?
How good is it to put visuals in space? allows us to monitor the remaining part of the electric spectrum that does not reach the land/sea.
Can a satellite see a person?

Can satellites see your face?
Unless you look up at the sky, where the satellite is, you can’t see all your faces. Spy satellites have scanners and can see the information below by reading vehicle registration documents. So it’s easy to see your face because you’re not just looking straight down but looking around like a bus.
Can spy satellites take video?
The problem: a network of pre -rotated satellite spies can capture images with impressive results, but they cannot capture images. In order to get around the lows required for their eyes to take good pictures, they have to move fast — too fast to take pictures.
What can spy satellites see?
They have a sample size of 5-6 inches, which means they can see anything 5 inches or more above the ground. These satellites probably can’t read your house number, but they can see if there is a bike parked in your street.
