Astronomers find these five chapters to be a handy way of conceiving the universe’s incredibly long lifespan.

The discovery could throw a wrench in the conventional wisdom surrounding the formation of galaxies.

One small step…just kidding, no steps are required.

We’re just counting down the final few days before we arrive to the Red Planet.

With less than two weeks before the country’s first-ever interplanetary mission slips into orbit around Mars, United Arab Emirates scientists can’t wait for the Hope orbiter’s arrival.

A look back at the Mars Curiosity rover’s science legacy thus far.

Before the Apollo era, the moon was thought to be dry as a desert due to the extreme temperatures and harshness of the space environment. Many studies have since discovered lunar water: ice in shadowed polar craters, water bound in volcanic rocks, and unexpected rusty iron deposits in the lunar soil. Despite these findings, there is still no true confirmation of the extent or origin of lunar surface water.

Three sun-studying spacecraft captured stunning images of the planets Venus, Earth, Mars and even Uranus.

Astronomers have found the first Jupiter-like exoplanet with no clouds or haze. It’s an ideal object for further study with the James Webb Space Telescope.

Can you picture Jupiter without any observable clouds or haze? It isn’t easy since Jupiter’s latitudinal cloud bands and its Great Red Spot are iconic visual features in our Solar System. Those features are caused by upswelling and descending gas, mostly ammonia. After Saturn’s rings, Jupiter’s cloud forms are probably the most recognizable feature in the Solar System.

Now astronomers with the Center for Astrophysics | Harvard & Smithsonian (CfA) have found a planet similar in mass to Jupiter, but with a cloud-free atmosphere.
