Scientists want to intercept any communication from aliens in a remote location in northern California. Unbelievable Facts about Life Beyond Earth. In a meadow situated among the volcanoes of the Cascade Range, 42 radio dishes point to the sky. The Allen Telescope Array, a gigantic scientific instrument, is made up of dishes, each of which is 20 feet wide. Scientists built the array to detect radio messages, which might answer a crucial question: Are we the only intelligent creature in this vast universe?
“It’s a question that humans have been asking for ages,” observes astronomer Jill Tarter. Until recently, she was the director of the SETI (Search for Extra-Terrestrial Intelligence) Institute in Mountain View, California. “We discovered that the ancient Greeks, Romans, and Chinese were all wondering how we humans fit into the cosmos when we examined this old literature.” The SETI Institute aided in the creation of the Allen Telescope Array in order to find answers.
While the question is not new, our understanding of the universe has developed throughout time. Stars, we now know, do not cling to the sky like fruit on a tree. We also know that the Earth circles the Sun rather than the other way around. But we still don’t know if there is life on other planets. And, if alien life exists, does it have the technology to communicate with us?
Here are 5 Unbelievable Facts about Life Beyond Earth;
1. Kepler Space Telescope Observation
Kepler Space Telescope Observation is one of the Unbelievable Facts about Life Beyond Earth .Kepler has radically revolutionized our understanding of exoplanets since its inception in 2009, detecting the great majority of the more than 5,000 potential exoplanets, of which over 1700 have been confirmed.
The Kepler probes yielded estimates of billions of planets in our galaxy, as well as the observation that the majority of planets within one astronomical unit are less than three times the diameter of Earth. Kepler also identified the first Earth-size planet to orbit a star in its “habitable zone,” which is the region where liquid water may form on the star’s surface.
2. Mars holds the most chance to support life
Mars holds the most chance to support life is one of the Unbelievable Facts about Life Beyond Earth, like Earth, may have once harbored life. NASA’s rover Curiosity has landed on Mars and is searching for habitats where life may have once existed. Curiosity led him to Yellowknife Bay, which had formerly been home to ancient lakes, and the lake water was neither too salty nor acidic, according to remnant minerals. Yellowknife Bay also included carbon, nitrogen, sulfur, phosphorus, and other essential elements for life. More crucially, Curiosity uncovered potential energy sources for tiny life there.Unbelievable Facts about Life Beyond Earth
3. When you look into the night sky, you are looking back in time is one of the Unbelievable Facts about Life Beyond Earth
The stars we see in the night sky are extraordinarily far away from us, and their light has traveled a huge journey across space to reach our eyes. This means that when we stare out into the night at the stars, we are witnessing how they appeared in the past. The dazzling star Vega, for example, is just 25 light-years away from us, thus the light we see left the star 25 years ago;
Unbelievable Facts about Life Beyond Earth yet, Betelgeuse (pictured) in the constellation Orion is 640 light-years away, so the light left the star about 1370, during the Hundred Years’ War between England and France. Other stars we see are considerably more away, so we are looking back in time.
4. The Voyager 1 spacecraft is the most distant human-made object from Earth
The Voyager 1 spacecraft is the most distant human-made object from Earth is one of the Unbelievable Facts about Life Beyond Earth Program launched two spacecraft, Voyager 1 and Voyager 2, in 1977. Over several decades, the probes explored our Solar System’s planets and moons, and they are now continuing their mission to travel beyond our Solar System’s heliosphere and into interstellar space.
On March 20, 2013, Voyager 1 became the first human-made object to leave the Solar System and is now the farthest human-made object from Earth, 124.34 Astronomical Units away. This equates to around 1.155812511010 miles. To put it mildly, you’re far from home.
5. It takes 225 million years for our Sun to travel around the galaxy
While the Earth and other planets in our solar system circle the Sun, the Sun itself revolves around the Milky Way, the galactic center. It takes the Sun 225 million years to complete a full circuit of the galaxy. When the Sun was at its current position in the galaxy, the supercontinent Pangaea was just breaking up, and the first dinosaurs appeared. It takes 225 million years for our Sun to travel around the galaxy is one of the Unbelievable Facts about Life Beyond Earth
No signs of genuine life have been discovered, however, there have been relics of prior life and possible life-sustaining environments, notably on Mars. So far, we have only been able to thoroughly study the few worlds that we have visited. Scientists believe that when technology advances on Earth, they will be able to explore and comprehend more about the cosmos that surrounds us.
