Why don't people use binoculars to gaze at the stars? Telescopes are not inherently better at looking into space than binoculars as both rely on the same optical principles to do the job. rocketstem.org/2026/10/06/wh…

50 years ago, NASA sent two spacecraft to search for life on Mars – scientists are still discussing today the results of these experiments in an attempt to answer the age-old question of whether there is life beyond the Earth. rocketstem.org/2026/09/28/50…

The Roman Space Telescope will use gravitational microlensing to detect planets around other stars without seeing the planets themselves. rocketstem.org/2026/09/24/ro…

The lunar surface fills the frame in sharp detail, as seen during the Artemis II lunar flyby, while a distant Earth sets in the background. This image was captured just three minutes before Orion went behind the Moon and lost contact with Earth for 40 minutes. Credit: NASA

Curious Kids: 12-year-old Phil asks what is space made of, and what does gravity actually bend? An astrophysics expert has the answers. rocketstem.org/2025/10/01/wh…

In this edition of Curious Kids, nine-year-old Clara asks if we can colonize Mars. rocketstem.org/2025/09/17/ca…

Curious Kids: 11-year-old Siah asks what is beyond outer space? Does the universe end? Or does it go on forever? That is a question for which scientists still don't have a definitive answer. rocketstem.org/2025/09/03/do…

In this edition of Curious Kids, Zayden asks why the Earth looks flat even though the planet is indeed a large sphere. A geomorphologist explains the 'flatness' is all a matter of perspective. rocketstem.org/2025/08/27/wh…

Nuclear rockets could travel to Mars in half the time − but designing the reactors that would power them isn’t going to be easy. rocketstem.org/2025/08/15/nu…
