Learn how solar prominences form, what drives their magnetic structure, and why these glowing plasma arches can persist for days or weeks.

A spacecraft impact can alter an asteroid’s speed, spin, shape, and trajectory while revealing its composition and interior structure.

Planetary defense is a global security challenge, and no single nation can monitor, deflect, or respond to every asteroid threat alone.

A clear look at how governments prepare for asteroid threats through detection, coordination, mitigation, and emergency response.

Explore why space robots need autonomy, from communication delays to mission safety, and how onboard intelligence changes exploration.

Scientists test planetary defense through simulations, asteroid tracking, impact experiments, and spacecraft missions that measure how to detect, deflect, and assess threats.

Early asteroid detection improves impact odds, response time, and planetary defense decisions before a threat becomes urgent.

Learn how spacecraft can alter an asteroid’s path using gravity, impact, thrust, and surface interaction techniques.

Explore how an asteroid impact would affect Earth, from blast waves and tsunamis to climate disruption and planetary defense.
