The Arecibo message as sent 1974 from the Arecibo Observatory.
Astrobiology is a field that is rapidly gaining momentum–due to scientific achievements such as the Curiosity Rover. This image should remind us of what we’ve achieved; how far we’ve come, and how much is still left to discover. The following excerpt, taken from Wikipedia, briefly explains the meaning of this image, along with its importance:
The Arecibo message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope on 16 November 1974. It was aimed at the globular star cluster M13 some 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony. The message consisted of 1679 binary digits, approximately 210 bytes, transmitted at a frequency of 2380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 1000 kW. The “ones” and “zeros” were transmitted by frequency shifting at the rate of 10 bits per second. The total broadcast was less than three minutes.
The cardinality of 1679 was chosen because it is a semiprime (the product of two prime numbers), to be arranged rectangularly as 73 rows by 23 columns. The alternative arrangement, 23 rows by 73 columns, produces jumbled nonsense. The message forms the image shown on the right, or its inverse, when translated into graphics characters and spaces.
Dr. Frank Drake, then at Cornell University and creator of the Drake equation, wrote the message, with help from Carl Sagan, among others. The message consists of seven parts that encode the following (from the top down):
1. The numbers one (1) to ten (10)
2. The atomic numbers of the elements hydrogen, carbon, nitrogen, oxygen, and phosphorus, which make up deoxyribonucleic acid (DNA)
3. The formulas for the sugars and bases in the nucleotides of DNA
4. The number of nucleotides in DNA, and a graphic of the double helix structure of DNA
5. A graphic figure of a human, the dimension (physical height) of an average man, and the human population of Earth
6. A graphic of the Solar System
7. A graphic of the Arecibo radio telescope and the dimension (the physical diameter) of the transmitting antenna dish.

I think that we should solve all of our problems instead of looking for trouble. But it is interesting to know from our surroundings, even those from space. I read the website of national geographic and it explained he point of exploring space

Carl Sagan—the dude I’m always raving about in class, and the creator of the series Cosmos, which I’ve shown in class a couple of times—contributed to the development of SETI. If we find ET life in the next few years, we will owe this discovery, in many ways, to the work of scientists like Carl Sagan: the best science teacher ever.

I agree that we are not alone in the universe. The universe is too big for just us to be living in it. Maybe we are superior than extraterrestrial kinds but we could also be equal or they could be superior to us.

I also believe it is very unlikely that this is the only planet with living beings in it but it is just as unlikely that we are the only intelligent life or that we are intellectually superior. Although as I see it, if any civilization is advanced enough to receive that message, it could also be advanced enough to find us or even wage war on us! This simple message in sent just for curiosity’s sake might just bring about an intergalactic war, and if so might have just doomed us all. I know it sounds kind of far fetched but its not impossible!

That would be so awesome. I would volunteer for an intergalactic war, defending planet Earth. I love Battlestar Galactica.

A very tempting description of the book. I want it:
““In April 2010, fifty years to the month after the first experiment in the Search for Extraterrestrial Intelligence (SETI), scholars from a range of disciplines—including astronomy, mathematics, anthropology, history, and cognitive science—gathered at NASA’s biennial Astrobiology Science Conference (AbSciCon) for a series of sessions on the search for intelligent life. This book highlights the most recent developments in SETI discussed at that conference, emphasizing the ways that SETI has grown since its inception.”

The message was sent, basically, to make a point regarding the nature of science; which, in many ways, like art, entails the human condition. The main focus of this point is that curiosity, more than almost anything, fueles scientific achievements.

In my opinion, as many other of the people who commented here, I do think that there are other living beings in other planets. But my question is, is it that we try to communicate with them and they do not want to be seen and this is why we have still not communicated with them, or is it that because of media like movies of aliens taken over our planet that we do not search enough to find those other living beings in those other planets?

It’s amazing to think that since our universe is so enormous that we are the only living beings known to our race. I believe it is very possible that other living organisms do exist, and just as the way that we have evolved they can also do the same.

The observatory has made major contributions to our understanding of the chemistry and dynamics of the Earth’s upper atmosphere and ionosphere.

Astrobiology is the branch of biology that studies life on earth and in space. In Puerto Rico we have the Arecibo radio telescope which is used for astrobiology. Even though we haven’t found any sign of life in other plantes I can’t believe that we are the only living organisms in the universe. We will never know everything, there is always something new to learn and discover and mayebe life on other planets is just something our technology can’t detect. Below there is a link that shows us the posibility of life on other planets but they are too far away to study.

Carl Sagan has also contributed in another message towards space. It is known as the pioneer plaque. There were two copies of the plaque that were placed on the Pioneer 10 and Pioneer 11 space crafts which were the first to leave the Solar System in 1972 and 1973. It was basically a few drawings and pictures of humans and were we come from. I liked how the man waving can was not only placed to show movement but as a greeting to anyone or anything out in space. I obtained most of the information from Wikipedia but I remembered it from a selection in one of our elementary English books.
