What's hovering above the Sun?

Europe's JUICE Jupiter probe lost contact with Earth for nearly a full day recently, but the problem was solved in time for its planned Aug. 31 Venus flyby.

Even if life never took hold on Ceres, the discovery could help broaden the range of environments that could potentially be habitable.

The rare sailback houndshark, which has an unusually large dorsal fin, was first described by scientists in 1973. That was the last record of its existence, until now

The dwarf planet is cold now, but new research paints a picture of Ceres hosting a deep, long-lived energy source that may have maintained habitable conditions in the past.

You know, if you think about it, and trust me we’re about to, the Moon is kind of weird.

How can thermoelectric generators (TEGs) help advance future lunar surface habitats? This is what a recent study published in Acta Astronautica hopes to address as a team of researchers from the Republic of Korea investigated a novel technique for improving power efficiency and reliability under the Moon’s harsh conditions. This study has the potential to help mission planners, engineers, and future astronauts develop technologies necessary for deep space human exploration to the Moon and beyond.

New analysis of human deep space communications suggests the most likely places to detect signals from an extraterrestrial intelligence.

How do you tell how old an astronomical object is? I mean, the next time the Moon is in the sky, take a look at it. How would you even begin to answer that question?

The 33rd SpaceX commercial resupply services mission for NASA, scheduled to lift off from the agency's Kennedy Space Center in Florida in late August, is heading to the International Space Station with an important investigation for the future of bone health.

Using stem cells from mice, researchers from Kyoto University tested the potential damage spaceflight can have on spermatazoa stem cells and the resulting offspring. After six months aboard the ISS, the stem cells were used to successfully produce healthy offspring.

A set of instruments shut off almost 50 years ago are still producing useful results. It’s the seismometers left by the Apollo missions to monitor moonquakes, which as the name suggests are earthquakes but on the Moon.

Comets are like the archeological sites of the solar system. They formed early on, and their composition helps us understand what the area around the early Sun was like, potentially even before any planets were formed. A new paper from researchers at a variety of US and European institutions used the Atacama Large Millimeter Array (ALMA) to capture detailed spatial spectral images of comet 12P/Pons-Brooks, which is very similar to the famous Halley’s comet, and might hold clues to where the water on the Earth came from.

In 2022, astronomers announced the discovery of GJ 3929b. It's a rocky planet, similar to Earth in both mass and size. Astronomers have examined the planet with the JWST and concluded that it's a barren world with no atmosphere.

Hulu's hit animated sci-fi show returns Sept. 15 with a 10-episode binge-worthy barrage.

Asteroid Ryugu is proving to be one of the most scientifically valuable time capsules in the solar system.

This quiz will challenge your knowledge of Mars' features, missions, and mysteries.

Stargazers will need a clear view of the western horizon to spot the moon near Spica as the sun sets on Aug. 27.

A new long-term study suggests that the more heat waves people are exposed to, the more their body’s aging process accelerates
