Ivy League Scientist Says NASA May Have Accidentally Spread Life to Mars

By Adam Barnes via The Hill Headline Image Credit: JPL/NASA Amid the latest exploration and search for life on Mars, a Cornell scientist wonders what kind of microbe humans could have accidentally “carried into space and survived the trip to make its new home on Mars.” Cornell University geneticist Christopher Mason wrote in an May 10 piece for the BBC … Continue reading

Scientists Discover Chemicals Needed for Life on Venus

By ADAM BARNHARDT via Headline image credit: Danielle Futselaar Scientists have discovered the potential for biological activity within the atmosphere of Venus. While researchers didn’t spot little alien guys flying around the planet in their spaceships, one recent journal study reveals the existence of phosphine in the planet’s atmosphere. Not only that, but Rakesh Mogul and other researchers from … Continue reading

Impact of Meteorites Led to Life-Giving Amino Acids on Earth, Study

Tetsuya Ishikura The Asahi Shimbun A simulation of how substances essential for living creatures were formed on Earth reinforces the theory that life started after meteorites rained down on the planet. Living organisms are said to have emerged on Earth 4 billion years ago. A large number of meteorites are believed to have bombarded the planet 200 million years before … Continue reading

Planetary Collision With Earth Created Moon, Left Elements Essential for Life

During it’s humble beginnings our planet was involved in some major collisions! via Unexplained-Mysteries: The carbon and nitrogen that make up our bodies likely came from a planet that once smacked in to the Earth. The early solar system was a particularly violent place, with cataclysmic collisions between protoplanets being a relatively common occurrence. One such collision, which saw the … Continue reading

ESA Spacecraft Looking for Proof of Life on Mars, We Could Know Within Months

ESA’s Trace Gas Orbiter has started its mission to seek out traces of biologically-produced methane on Mars. The spacecraft, which achieved a stable orbit earlier this month, is now actively seeking out traces of methane in an attempt to determine whether or not there is life on Mars. According to scientists, an answer to the mystery may come within the … Continue reading

Asteroids May be Crucial in the Search for the Chemical Origins of Life

Asteroids are often thought to be a threat to life, but could they be the key finding out how the Earth evolved into the thriving planet which we know today? Nicholas Hud, director of the Center for Chemical Evolution at the Georgia Institute of Technology, thinks so and has been studying space rocks in an effort to pinpoint the chemical … Continue reading

‘Life’ in the Universe is Common Based on Ancient Fossil Microorganisms

A new analysis of the oldest known fossil microorganisms provides strong evidence to support an increasingly widespread understanding that life in the universe is common. The microorganisms, from Western Australia, are 3.465 billion years old. Scientists from UCLA and the University of Wisconsin–Madison report today in the journal Proceedings of the National Academy of Sciences that two of the species … Continue reading

Life That Exists on Earth May Already Exist on Alien Planets – Scientists

Life forms on Earth may also exist on other planets, according to a theory on micro-organisms from our solar system. Scientists studying interplanetary dust have posited that the powdery matter is capable of transporting tiny organisms across the cosmos. Edinburgh-based scientists claim bacteria and micro-animals called tardigrades can survive the hazardous journey, suggesting that alien bugs may have arrived on … Continue reading

Potential ‘Missing Link’ Chemical that Led to Life on Earth Found by Scientist

Chemists at The Scripps Research Institute (TSRI) have found a compound that may have been a crucial factor in the origins of life on Earth. Origins-of-life researchers have hypothesized that a chemical reaction called phosphorylation may have been crucial for the assembly of three key ingredients in early life forms: short strands of nucleotides to store genetic information, short chains … Continue reading

Life May Have Started Even Sooner than Once Thought

Earth was once bombarded by comets and asteroids. Scientists have made a discovery that could push back the emergence of life further than ever before. The controversial findings are based on a recent analysis by researchers in Japan of graphite particles found in rocks from the Saglek region of northern Labrador, Canada. The results of the study indicate that the … Continue reading
