When a skyscraper-sized asteroid narrowly misses Earth in 2029, three spacecraft may be along for the ride.
What would happen if we nuked an asteroid?
Detonating a nuclear weapon on or near an asteroid is one of several options for defending the Earth from an impact. Here's what nuking an asteroid might actually do, and why it isn't always the best option.
Mars may host oceans’ worth of water deep underground
The tentative discovery hints at an habitat where life could potentially thrive.
Eureka? Scientists’ first hints of life on other planets may not be so obvious
Knowing that you've found signs of life beyond Earth may not be as clear-cut and simple as one might think.
