To study the boundary of interstellar space, scientists studied cosmic rays moving towards Earth from different parts of the galaxy.
Experts confirmed that the rocks were from a meteorite that fell recently, since samples show a half-life of some elements being only a few days.
The grains of sand is about 2.5 billion years before the Sun, Earth and rest of our solar system were formed.
Mobile phone cameras use technology similar to that in particle detectors and hence they are able to detect EAS.
Researchers have found that some ultra-high energy cosmic rays that occasionally hit Earth come from a distant source outside the Milky Way.

Astronauts travelling to Mars or on long-term missions could face much higher cancer risk than conventional risk models suggest.
The world's largest and most sensitive cosmic ray monitor, located in India, has recorded a burst of galactic cosmic rays that indicates a crack in the Earth's magnetic shield, according to scientists.
Cosmic rays have created radiation hazards in space that potentially threaten future deep-space astronaut missions to Mars, said researchers.
