Space Dust Could Be Bringing Alien Life to Earth
Life never ceases to surprise, even when faced with the unforgiving environment of space.
Hollywood almost always portrays our first encounter with extraterrestrials as humans confronting a big, shiny spacecraft, piloted by organisms with technology far beyond our own. More likely, it’ll be alien microbes we first encounter. And it may not just be on other moons or planets. It could be right here on Earth. How? They may be hitching a ride on space dust.
Typically, 4,000 tons of micrometeorites fall to Earth every year, each about the width of a human hair. Amateur scientist Jon Larsen collaborated with a number of scientists earlier this year and wrote about the phenomenon in the journal Geology. He’s also authored a book entitled, In Search of Stardust: Amazing Micro-Meteorites and Their Terrestrial Imposters.
More recently, a researcher at the University of Edinburgh went a step further. Arjun Berera, a professor in the physics and astronomy department at the University of Edinburgh, discovered that space dust moves at such a high velocity that it could possibly bring alien microbes to our planet. His findings were published in the journal Astrobiology.
“It is observed that hypervelocity space dust, which is continuously bombarding the Earth, creates immense momentum flows in the atmosphere,” Berera writes. “Some of this fast space dust inevitably will interact with the atmospheric system, transferring energy and moving particles around, with various possible consequences.”

Berera continued, “Floating in the Earth's atmosphere are a variety of particles containing the telltale signs of Earth's organic story, including microbial life and life essential molecules.” What he found was that cosmic dust flows can travel up to 43 miles per second (70 km per second). These collide constantly with organic particles in the upper atmosphere, which might generate enough energy to send them careening into space. “The same mechanism could enable the exchange of atmospheric particles between distant planets,” according to a press release.
Such flows are thought to constantly move between planets. This would theoretically take bacteria and eventually distribute them elsewhere, perhaps even seeding life on other moons and planets in our solar system and beyond. Before this, it was thought that only large asteroid impacts could transmit life through space.
According to a press release, “Some bacteria, plants and small animals called tardigrades are known to be able to survive in space, so it is possible that such organisms – if present in Earth’s upper atmosphere – might collide with fast-moving space dust and withstand a journey to another planet.” Case in point, bacteria was recently found living on the outside hull of the International Space Station, which one cosmonaut claims is alien in origin—though no proof has yet surfaced.

This paper also strengthens the case for what’s been, up until now, considered a radical theory, panspermia. It states that life on our planet was seeded by space-faring molecules or microbes from elsewhere in the solar system, most likely Mars.
“The proposition that space dust collisions could propel organisms over enormous distances between planets raises some exciting prospects of how life and the atmospheres of planets originated,” Barera said. “The streaming of fast space dust is found throughout planetary systems and could be a common factor in proliferating life.”

The team caught a glimpse of a process that takes 18,000,000,000,000,000,000,000 years.
- In Italy, a team of scientists is using a highly sophisticated detector to hunt for dark matter.
- The team observed an ultra-rare particle interaction that reveals the half-life of a xenon-124 atom to be 18 sextillion years.
- The half-life of a process is how long it takes for half of the radioactive nuclei present in a sample to decay.
Humans are particularly prone to shiver when a group does or thinks the same thing at the same time.
A few years ago, I proposed that the feeling of cold in one's spine, while for example watching a film or listening to music, corresponds to an event when our vital need for cognition is satisfied.
Certain colors are globally linked to certain feelings, the study reveals.
- Color psychology is often used in marketing to alter your perception of products and services.
- Various studies and experiments across multiple years have given us more insight into the link between personality and color.
- The results of a new study spanning 6 continents (30 nations) shows universal correlations between colors and emotions around the globe.
