ICESat-2's instrument, ATLAS, is designed to measure heights on Earth. ATLAS has three main tasks: transmitting a pattern of six laser beams, collecting the laser photons that return to the satellite after reflecting off Earth, and...

In celebration of the 31st anniversary of the launching of NASA’s Hubble Space Telescope on April 24, 1990, astronomers aimed the renowned observatory at a brilliant “celebrity star,” one of the brightest...

The Hubble Space Telescope has been revealing the secrets of the universe for over 30 years, but it turns out Hubble has some secrets of its own!



The question is: Hubble observed what...

Dubbed Ariel, the spacecraft is expected to launch in 2029 on ESA’s new Ariane 6 rocket.

On schedule to launch in the mid-2020s, NASA’s Wide Field Infrared Survey Telescope (WFIRST) mission will help uncover some of the biggest mysteries in the cosmos. The state-of-the-art telescope on the...

The James Webb Space Telescope is one the most ambitious, and technically complex missions NASA has ever set its focus on. Building an infrared observatory of this magnitude, power and complexity has never been attempted...

Humans have always looked up at the sky. They used astronomy to track time, orient their cities, decide when to plant their crops, and even based their religious practices on their celestial world. But there was much more to learn.<br/>

International Observe the Moon Night 2020 welcomed participants from all 7 continents, 103 countries, all 50 U. S. states, Guam, Puerto Rico, the U. S. Virgin Islands, and Washington, D.C. Hear from...

Understanding the Sun’s behavior is an important part of life in our solar system. The Sun’s powerful outbursts can disturb the satellites and communications signals traveling around Earth, or one day, Artemis...
