In honor of SciAm’s 180th birthday, we’re spotlighting the biggest “wait, what?” moments in science history.

The European Space Agency’s Jupiter Icy Moons Explorer (Juice) is on track for its gravity-assist flyby at Venus on 31 August, following the successful resolution of a spacecraft communication anomaly that temporarily severed contact with Earth.

The issue, which emerged during a routine ground station pass on 16 July, temporarily disrupted Juice’s ability to transmit information about its health and status (telemetry).

Thanks to swift and coordinated action by the teams at ESA’s European Space Operations Centre (ESOC) in Darmstadt, Germany, and Juice’s manufacturer, Airbus, communication was restored in time to prepare for the upcoming planetary encounter.

NASA's Psyche spacecraft, which is headed toward a big and bizarre metal asteroid, has delivered a stunning perspective of our home planet from deep space.

SpaceX scrubbed the planned 10th test flight of its Starship megarocket today (Aug. 24), citing a problem with ground systems at its Starbase site in South Texas.

This galaxy is not only pretty -- it's useful.

A SpaceX cargo ship arrived at the International Space Station on Aug. 25 carrying about 5,000 pounds (2,270 kilograms) of food, supplies and scientific experiments.

From the semi-annoying antics of 'ALF' to 'Knight Rider's' awesome autonomous auto, the 1980s were a transitional time for stimulating small-screen science fiction!

A new wave of climate research is sounding a stark warning: Human activity may be driving drought more intensely — and more directly — than previously understood.

If black holes are actually droplets of dark energy that convert stellar matter into this mysterious and dominant force, many "cosmic hiccups" could soon be cured.

How do tidal forces determine a planet’s orbital evolution, specifically planets in the habitable zone? This is what a recently submitted study hopes to address as an international team of researchers investigated how tidal forces far more powerful than experienced on Earth could influence orbital evolution of habitable zone planets with highly eccentric orbits around low-mass stars. This study has the potential to help researchers better understand the formation and evolution of exoplanets, specifically regarding where we could find life beyond Earth.

Some scientists thought that the asteroids Ryugu and Bennu were from the same family. Now that they have samples and JWST spectra from both, the verdict is in: They're both from the Polana collisional family, a diverse and widespread family of asteroids.

Astronomers have discovered what may be a massive star exploding while trying to swallow a black hole companion, offering an explanation for one of the strangest stellar explosions ever seen.

NASA will announce its new astronaut class in September, as well as details about the Artemis 2 crewed mission around the moon.
