Bacteria From Earth Can Survive In Space and Could Endure the Trip To Mars, Says Study
AmiMoJo shares a report from CNN: A type of bacteria that is highly resistant to radiation and other environmental hazards survived outside of the International Space Station for three years, according to a new study. The Japanese Tanpopo mission involved including pellets of dried Deinococcus bacteria within aluminum plates that were placed in exposure panels outside of the space station. Deinococcus…
Bacteria could survive travel between Earth and Mars when forming aggregates
Imagine microscopic life-forms, such as bacteria, transported through space, and landing on another planet. The bacteria finding suitable conditions for its survival could then start multiplying again, sparking life at the other side of the universe. This theory, called “panspermia”, support the possibility that microbes may migrate between planets and distribute life in the universe. Long controversial, this theory implies that…
Is ‘Oumuamua a fragment of a shattered super-Earth?
Computer simulations confirm that ‘Oumuamua – an object from another star system that sped near our sun in 2017 – likely formed via a close encounter with its star. ‘Oumuamua may have originated in a debris disk, they said, or even a shattered super-Earth.

Did ancient Earth life escape our solar system?
You’ve heard of panspermia, the idea that life exists throughout space and was carried to Earth by comets? What if the reverse occurred, with microbes on Earth ejected into space by asteroid impacts, escaping into the solar system billions of years ago?

Plant seeding and panspermia
The first detection of an interstellar asteroid/comet-like object visiting the Solar system two years ago has sparked ideas about the possibility of interstellar travel. New research from the Technion–Israel Institute of Technology suggests that such objects also raise far reaching implications about the origins of planets across the galaxy, and possibly even the initial formation of the Solar system itself.
