In 1619, German astronomer Johannes Kepler published his Harmonices Mundi (Harmony of the World), a text that investigated how mathematics could help the planets of the solar system create celestial music based on their orbital resonances.

We might need to rethink our understanding of water, both on Earth and other planets. New experiments with water ice at high pressures has revealed unexpected behaviour, which could upend our assumptions about the makeup of icy exoplanets.

Jason Steffen, an associate professor of physics and astronomy at the University of Nevada at Las Vegas, has more than 7,000 Twitch followers and uses the platform to practice future lectures.

The star around which astronomers got their first-ever sighting of a fledgling planet has been shown to have another world and possibly even a giant moon-forming disc.

Astronomers have spent decades, if not centuries, hoping to see embryonic planets. As of a year ago, the closest they had come was the discovery of gaps, thought to be caused by budding planets, in the spinning disks of gas and dust that surround young stars. But they weren’t sure how to interpret these indirect clues.

A global helium shortage is impacting businesses large and small. Local businesses that rely on the non-renewable gas are making due without any idea of when or if helium will be readily available again.

After 30 years of searching, the helium hydride ion, the first chemical bond that was formed in the Universe, has finally been detected outside the laboratory, in the interstellar medium.

A major helium shortage could deflate your next party or celebration.

After more than three years of talks and repeated threats of federal intervention, water officials in seven Western states still haven’t quite finished an emergency drought plan for the Colorado River.

Neon has proven to be a very important and a storied part of Nevada's history -- in particular, in Las Vegas.
