It's been a long time that scientists across the globe have been working to establish the truth that there are some sorts of small life-forms on other habitable planets around the cosmos.
While researchers are working hard to communicate with those alien lives far beyond our solar system, someone or something from those neighbouring planet may also send a message back to our planet earth anytime soon.
Amidst these ongoing debates, sparked over the existence of aliens, the latest study led by Arjun Berera from the University of Edinburgh has shaken people all over the world.
The latest findings, published in the journal 'Astrobiology' suggests that life from Earth may already exist on alien planets after being carried by tiny specks of space dust, while some smaller life-forms might be able to travel across star systems using those speeding space dust as well.
The group of scientists also believes that the tiny organisms are even able to reach any planets in the solar system. Earlier researchers have proved that some bacteria, plants and even hardy micro-animals called tardigrades are able to survive in space.
Berera examined the travelling speed of those moving flows of space dust and further found that when incoming grit collides with our planet's atmosphere, the impact could knock small particles in our upper atmosphere beyond the pull of Earth's gravity, possibly sending it on a journey to other planets.
According to Berera the flows of space dust can travel at speeds up to 70 km per second.
"The streaming of fast space dust is found throughout planetary systems and could be a common factor in proliferating life," Berera was quoted while talking about his latest research in a news release on Monday.
"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," Berera added further.
If the report turns out to be true then it indicates that life could have been seeded on Earth and perhaps elsewhere from a dust cloud, rather than by comet and asteroid impacts as previously thought.
It seems like ancient astronauts have been visiting Earth and trying to communicate with us this whole time but we failed to spot them since we have been looking for them with telescopes instead of microscopes.
Earlier, METI scientists had sent an encoded radio message to a neighbouring star system namely GJ 273 or Luyten's star and are expecting that aliens will send a message back within 25 years.
Hence, the latest attempts have raised the ray of hope further and enthusiasts are waiting eagerly to get a significant response from those mysterious lives anytime soon.
