Could Alien Microbes Live Off Products of Radioactive Decay?
Microbes living beneath the seafloor feed largely on the products of radioactive decay, aided by sediment of the seafloor, a new study reveals. This finding radically changes how we look at life processes in one of the largest ecosystems on our planet. It could also alter our views of how life may have evolved on Mars or other alien worlds.

Stunning New Images of Venus from the Parker Solar Probe
The Parker Solar Probe, designed for detailed study of the Sun, has another advantage - it is able to examine planets as it passes their orbits. As it refines its orbit around our Sun, Parker will pass Venus a total of seven times over its seven-year mission. The Parker probe uses the gravitational pull of planets to bend its path through the Solar System.
