The storied career of the Delta family of rockets had to wait a little longer than planned to turn the page on its final chapter, but the last of its kind lifted off on the Space Coast on April 9.
For the northern hemisphere observers, November is fireball season. This month, keep an eye out for two sure-fire annual meteor showers, and—just maybe—a wild card outburst from the obscure Alpha Monocerotids worth watching ...
Comets are known to have a temper. As they swoop in from the outer edges of our solar system, these icy bodies begin spewing gas and dust as they venture closer to the sun. Their luminous outbursts can result in spectacular ...
Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan's Hayabusa2 spacecraft dropped a copper projectile at very high ...
ESA's planet-defending Hera mission will set a new record in space. The asteroid investigator will not only be the first spacecraft to explore a binary asteroid system – the Didymos pair – but the smaller of these two ...
The entire history of human existence is a tiny blip in our solar system's 4.5-billion-year history. No one was around to see planets forming and undergoing dramatic changes before settling in their present configuration. ...
NASA's Spitzer Space Telescope has spent 15 years in space. In honor of this anniversary, 15 of Spitzer's greatest discoveries are featured in a gallery.
Initially scheduled for a minimum 2.5-year primary mission, NASA's Spitzer Space Telescope has gone far beyond its expected lifetime—and is still going strong after 15 years.
Solid-state batteries contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling, and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion ...
Iron-air batteries promise a higher energy density than present-day lithium-ion batteries. Their main constituent, iron, is an abundant and cheap material. Scientists from Forschungszentrum Jülich are pursuing research into ...
