Sir Brian May is among a band of scientists and astronomers who are highlighting the threat to humanity by asteroids, and they have named June 30 as "Asteroid Day" to help raise funds for building orbiting space observatory Sentinel.
Queen rocker is helping scientists raise 160 million pounds to save the world from Earth-killing asteroid attacks, the Mirror has reported.
Supporters other than guitarist May include Martin Rees, the astronomer royal; biologist Richard Dawkins; Apollo 9 astronaut Rusty Schweickart; Nobel laureate Sir Harold Kroto; British astronaut Helen Sharman; and cosmonaut Alexey Leonov.
Their aim would be to highlight the dangers facing Earth and track deadly asteroids that may be lurking in near-Earth space.
