Space is full of hazards, from asteroids to black holes, but most threats are less immediate than they seem. The odds of asteroid Apophis hitting Earth in 2036 were once 1 in 625, but scientists now say the risk is extremely low. The sun has enough fuel to last billions of years, and the galaxy’s supermassive black hole is safely distant. Despite dramatic dangers, life on Earth remains far more vulnerable to everyday risks than to cosmic disasters.
