Astrophysicist Says We Should Find Extra Terrestrial Life Sometime In The Next 100 Years

The frontier for scientific knowledge is expanding at a phenomenal rate. It’s hard to believe that less than 20 years ago, there was no evidence of extra solar planets even existing and yet now we have confirmed the existence of 783 of them, with thousands more waiting on conclusive data. It’s this seemingly exponential growth of knowledge in the realm of astronomy that leads astrophysicist Jocelyn Bell Burnell to believe that we will find the answer to that all important question, “Are we alone?” some time this century.

At the 5th Euroscience Open Forum conference in Dublin, Dr. Burnell announced her expectations that we should be seeing evidence of alien life very soon. According to DailyMail, Dr. Burnell  isn’t just hopeful that we’ll find evidence of alien biospheres, but that we might even stand a chance at spotting intelligent extraterrestrial life.  Dr. Burnell  isn’t some crackpot wearing a tinfoil beanie though, she is the respected astrophysicist who was responsible for discovering the first pulsar. In her opinion, governments and world leaders should already be working on plans for what to do when we finally find hard evidence for the existence of extra terrestrials. According to Dr. Burnell…

 I do suspect we are going to get signs of life elsewhere, maybe even intelligent life, within the next century.

How well prepared are we? Have we thought of how we approach them? Should we put them in a zoo, eat them, send in GIs to bring them democracy?

This Martian Meteorite Suggests Extraterrestrial Life

MarsScientists and researchers believe that life on Earth may have come from Mars. We know that something needed to kick start life in the primordial soup that was the newly-formed planet Earth, and no one knows for certain where that initial boost came from. Most scientists, however, believe that that life arrived at Earth courtesy of a meteorite.

One of the possibilities is that such a meteorite came from Mars, as many meteorites do. Of course, suggesting that human life actually started on another planet is a controversial theory, but one that just received a boost due to newly released information gleaned from the analysis of a Martian meteorite.

Scientists Appeal To Congress To Support Technology To Search for Extraterrestrial Life

candidate planetsGiven how many candidate planets Kepler has identified, and the recently announced estimate that billions of habitable planets may exist in the Milky Way alone, scientists are understandably excited about the prospect of finding alien life. They’re so excited, in fact, that they made a plea to Congress this week to embark on the next phase of searching for life.

Sara Seager, MIT’s exoplanet expert who came up with her own equation to express the probability of finding extra-terrestrial life, spoke at the “Astrobiology: The Search for Biosignatures in our Solar System and Beyond” hearing of the House Committee on Science, Space and Technology and argued that while we have some technology capable of detecting candidate planets and other life forms, we need more. “This is the first time in human history we have the technological reach to find life on other planets,” she said. “People will look back at us as the ones who found Earth-like worlds.” NASA’s head of astrobiology seconded that, saying that humans finally have the means to gather data about other life forms in the universe, which means it’s incumbent upon us to do so.

We May Not Be Alone: British Scientists Claim To Have Proof Of Extraterrestrial Life

Alien LifeOne of the biggest questions that has plagued the human race since we crawled out of the primordial soup is are we alone? Some people look to the heavens for God, for some creator, while others search among the stars for life beyond our own world. If a team of British scientists is correct, then we may have a definitive answer, because they claim to have proof of alien life.

The scientists, who claim to be “95 per cent convinced” of their discovery, have gathered biological organisms from the very edge of our atmosphere, and claim that they could only have originated in space. A team sent a balloon 27 kilometers into the stratosphere to collect samples, and when it returned, they found something interesting.

NASA May Use A Probe Fleet To Search Mars For Extraterrestrial Life In 2018

MarsThe search for extraterrestrial life has been and always will be one of mankind’s greatest journeys. Into the depths of space we’ve sent many probes that have returned nothing but our own bleeps and bloops that have been lost in the ever-expanding cosmos. But maybe we’ve been looking too far away.

Mars is our closest celestial neighbor, after our moon of course, and we may not find Marvin the Martian puttering about on its surface, but Washington State Universtiy’s Dirk Schulze-Makuch thinks that with a small effort we may uncover early forms of life just beneath the red planet’s harsh surface. In an interview with Space.com, Schulze-Makuch outlined his idea to send six probes to the martian surface that once landed will dig four to eight inches into the soil and begin a series of tests that will reveal whether or not microscopic life exists.

These sorts of missions have largely been overlooked since the first hunt for life on Mars, 1975’s Viking mission, returned didley squat. However, Schulze-Makuch’s proposed mission will only cost an estimated $300 million, which sounds a lot to you and me, but in NASA’s world this is peanuts.

Curiosity Rover Discovers This Evidence For Past Life On Mars

fb share tweet share

curiosityOne of the goals of the Curiosity Rover is to try to find evidence indicating whether life ever existed on Mars. Thanks to its work so far, we know that Mars still retains water in its surface soil. Scientists also know that Mars used to be warmer and wetter than it is now. Examinations of meteorites of Martian origin reveal organic compounds, suggesting not only that conditions there were once favorable, but that the planet did indeed harbor life. Now, Curiosity has found additional evidence supporting both of those hypotheses.

In order to determine whether life has ever existed on Mars, scientists have been looking for evidence of three criteria: water, life-supporting elements (carbon, oxygen, hydrogen, nitrogen, phosphorus), and a long enough period of time in which those conditions were present. It’s that last part that has proven problematic, as previous estimates about the amount of time when those conditions existed was in the neighborhood of hundreds of thousands of years—not very long at all when it comes to creating life out of chemical soup.
