What satellites leave behind
Metals from reentering objects are accumulating in the stratosphere in what amounts to an uncontrolled geoengineering experiment.
Our increasingly cluttered skies
As Earth’s orbital space becomes ever more crowded, collisions and debris threaten not only commercial assets and astronauts’ lives, but also safety and property on the ground.
How Roman will unlock the universe
This next-generation space telescope will blow past its predecessors to answer questions about everything from stars and planets to dark matter and dark energy.
Our 16th annual Star Products
Each year, new astronomy equipment reflects advances in technology and the evolving ways observers engage with the night sky. Traditional designs such as Dobsonian reflectors and apochromatic refractors continue to deliver dependable performance, while smart telescopes and integrated imaging systems are expanding access to astrophotography.
Artemis 2 brings back Moon joy
After a long road to launch, Artemis 2 was a rousing success that captivated the world for 10 days.
Fueling our lunar return
