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.

A new wave of delusional thinking fueled by artificial intelligence has researchers investigating the dark side of AI companionship

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 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.
