A discovery of life beyond the earth

Stephen Ornes Jun 27, — Seth Shostak If aliens ever sent us a message, scientists hope to pick it up in a remote part of northern California. There, in a clearing nestled amid the volcanoes of the Cascade Range, 42 radio dishes point together at the sky. The dishes, each 20 feet across, form a single, giant scientific instrument called the Allen Telescope Array.

A discovery of life beyond the earth

NASA: Nearby ocean worlds could be best bet for life beyond Earth - CNN A huddle of seven worlds, all close in size to Earth, and perhaps warm enough for water and the life it can sustain, has been spotted around a small, faint star in the constellation of Aquarius. This discovery is a lottery win for astronomers looking for life beyond Earth Read more The discovery, which has thrilled astronomers, has raised hopes that the hunt for alien life beyond the solar system could start much sooner than previously thought, with the next generation of telescopes that are due to switch on in the next decade.
Signs of Alien Life Will Be Found by , NASA's Chief Scientist Predicts Religious faith remains strong in much of the world despite scientific advances showing that Earth is not the center of the universe, and that our planet's organisms were not created in their present form but rather evolved over billions of years.

Using Spitzer, Gillon and his colleagues watched Trappist-1 nonstop for 20 days or 34 transits. In combination with ground observations, the scientists have now concluded that a total of seven planets orbit the dwarf star.

They published their findings yesterday in the journal Nature. Hurt IPAC Though the planets in the Trappist-1 system are all about the same size as Earth, they orbit in extremely tight circles around their star, compared to the planets in our solar system.

New Super-Earths May Support Life

In this way, the system is more similar to the moons of Jupiter than to a larger planetary system like our solar system. The orbital resonance suggests that the planets formed farther out from Trappist-1 and then moved inward.

This makes it more likely that they could contain some form of water, as volatile compounds molecules that easily turn to gas like water are usually concentrated further out in star systems. The system is also within the range of the James Webb Telescope, scheduled for launch next year, which will be able to detect both atmospheric components and thermal emissions from the planets.

This means one side of each planet always faces the star, while the other is always in darkness.

This would cause far more dramatic weather patterns than we see on Earth, including big temperature swings and strong winds. But even if no life is found on any of the seven Trappist-1 exoplanets, the system will still be hugely exciting for scientists to investigate. Now, for the first time ever, the search for the conditions in which life can or cannot exist on planets outside our solar system is not just a matter of speculation, but of observation.Scientists develop new strategies to discover life beyond earth June 28, , Tokyo Institute of Technology An overview of the past, present, and future of research on remotely detectable.

— The discovery of life beyond Earth would shake up our view of humanity's place in the universe, but it probably wouldn't seriously threaten organized religion, experts say. The discovery, which has thrilled astronomers, has raised hopes that the hunt for alien life beyond the solar system could start much sooner than previously thought, with the next generation of.
