| NASA taps the power of zombie stars in two-in-one instrument Posted: 08 Apr 2013 12:53 AM PDT Neutron stars have been called the zombies of the cosmos. They shine even though they're technically dead, occasionally feeding on neighboring stars if they venture too close. Interestingly, these unusual objects, born when a massive star extinguishes its fuel and collapses under its own gravity, also may help future space travelers navigate to Mars and other distant destinations. NASA recently selected a new mission called the Neutron-star Interior Composition Explorer (NICER) to not only reveal the physics that make neutron stars the densest objects in nature, but also to demonstrate a groundbreaking navigation technology that could revolutionize the agency's ability to travel to the far reaches of the solar system and beyond. |
