Space Algae Claims Scoffed By Science Community
2013-03-12 10:23:24

Brett Smith for redOrbit.com - Your Universe Online Instead of being hailed as the definitive proof of extraterrestrial life in the form of space algae, a new report from the Journal of Cosmology claiming drawing howls and catcalls from around the scientific community. The report is based on supposed meteorite fragments taken from a fireball that appeared in the evening sky over northern Sri Lanka on Dec. 29, 2012. An analysis of the fragments was performed by Chandra Wickramasinghe,...

Missing Mass: Lone Wolf Planets Outnumber Milky Way Stars

Researchers say life-bearing planets may exist in vast numbers in the space between stars in the Milky Way A few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way. So argues an international team of scientists led by Professor Chandra Wickramasinghe, Director of the Buckingham Centre for Astrobiology at the University of Buckingham, UK. Their findings are published online in the Springer journal Astrophysics and...

Comets held a vast ocean of water in their interiors during the first million years after their formation, a study by a Welsh university says. The liquid environment of early comets, along with the large quantity of organic matter already discovered, would have provided great culture for primitive bacteria to grow and multiply, researchers at Cardiff University said Thursday in a release. The team calculated the thermal history of comets after they were formed from interstellar and...

Comets contained vast oceans of liquid water in their interiors during the first million years of their formation, a new study claims. The watery environment of early comets, together with the vast quantity of organics already discovered in comets, would have provided ideal conditions for primitive bacteria to grow and multiply. So argue Professor Chandra Wickramasinghe and his colleagues at the Cardiff Centre for Astrobiology in a paper published in the International Journal of...

Cardiff study suggests link between comet bombardment and movement through the galaxyThe sun's movement through the Milky Way regularly sends comets hurtling into the inner solar system "“ coinciding with mass life extinctions on earth, a new study claims.Scientists at the Cardiff Centre for Astrobiology built a computer model of our solar system's movement and found that it "bounces" up and down through the plane of the galaxy. As we pass through the densest part of the plane,...

Researchers at Cardiff University believe that recent probes inside comets show it is overwhelmingly likely that life began in space. Professor Chandra Wickramasinghe and colleagues at the University's Centre for Astrobiology have long argued the case for panspermia - the theory that life began inside comets and then spread to habitable planets across the galaxy. It is a controversial topic, but highly relevant for astrobiologists trying to understand the origin of life and potential for...

Cardiff (UK) scientists are playing a major role in a NASA mission, which they believe could reveal living matter in the icy layers beneath the surface of a comet. NASA's Deep Impact spacecraft will make a historic encounter with Comet Tempel-1 on 4th July, when a metre-long projectile will crash into the comet and tunnel through its outer layers, producing a crater and a plume of gas and dust. UK astronomers involved in monitoring the comet before, during and after the impact and...

'Micro-organisms could also prompt rainfall' Micro-organisms in clouds could play a crucial role in the spread of disease and in the formation of rain drops, scientists have claimed. The radical theories about nanobacteria "“ micro-organisms considerably smaller than ordinary bacteria - in clouds are published in two recent articles in the Journal of Proteome Research by Dr Andrei P. Sommer of the University of Ulm, Germany, and Professor Chandra Wickramasinghe of Cardiff University,...
