Three new space missions set to launch Tuesday morning. What they entail and why they are critical to future human space flights.

NASA is gearing up to launch the Interstellar Mapping and Acceleration Probe (IMAP), a mission aimed at exploring the farthest reaches of our solar system.

Scientists can say two things with certainty about Io. First, this moon of Jupiter is the most volcanic object in the known universe. Its surface is festooned with so many lava-spewing calderas that it resembles an oven-baked cheese pizza; its glowing ...

NASA’s IMAP mission, led by Princeton University’s David McComas, will study the heliosphere — the invisible electromagnetic shield that protects our solar system — to better understand this mysterious boundary and provide critical solar storm monitoring.

The Solar System is vast, made up of eight planets, countless moons, and millions of asteroids, all orbiting the Sun. But like any territory, it has a boundary. This boundary is invisible, yet it marks the end of the Sun’s influence.

Plus, catch Saturn and Neptune at their brightest; spy the "string of pearls" galaxy; and a close encounter of the moon and Jupiter.

Discover the powerful volcanic eruptions that have shaped worlds across our solar system. Around our solar system, violent eruptions are shaping distant worlds. Discover the explosive forces that helped create some of the most dynamic worlds in our cosmic ...

UB students huddled in the Hochstetter Hall volcanology lab, passing around a plexiglass disk. Inside was what at first glance appeared to be unremarkable pebbles and dust but was actually some of the oldest material in our solar system: moon rocks.
