The international LIGO-Virgo-KAGRA Collaboration reports the observations of two record-breaking events in gravitational wave observations. They were detected in October and November 2024, and they might be a crucial step forward in our understanding of the ripples in space-time and the events that create them.

A pair of once-in-a-lifetime comets are rocketing through our skies right now, and it's a rare treat because they won't be back for hundreds of years. The comets, C/2025 A6 (Lemmon) and C/2025 R2 (SWAN), look similar. Both comets have already had their brightest nights on Oct. 20 and Oct. 21. But if you're out and about this final week of October, you can still spot these green gaseous globes and their streaming tails.

Metallicity is a fundamental part of the Universe. The Big Bang created mostly hydrogen, the simplest and lightest element, and a tiny bit of helium, the second lightest element. Those elements gather together in large quantities to form stars. For rocky planets to form, stars had to form first.

A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy—and why the life and death of nearby stars are an important piece of the puzzle.

There are an estimated 23 active rocket launch facilities across the globe, but a massive increase in launch requests from the satellite industry is spurring demand for more capacity, especially when it comes to rockets.

On an episode of the popular podcast Good Hang with Amy Poehler, British actor Idris Elba and the host (the former star of Parks and Recreation) are bonding over the aches and pains that arise in your 50s. Elba mentions that he's a big fan of grounding as a way to reduce inflammation and stiffness. He notes that a lot of people are skeptical of the wellness ritual, "but it works."

Federal investment in science and engineering research plays a key role in growing our economy and driving innovation in Nevada. Cuts and disruptions to this funding threaten our students and our future workforce and economic base.

Astrophysics professor and Afternoon Shift fan favorite, Mike Pravica, drops by The Afternoon Shift to chat all things space and our weird and wonderful universe.

The average person likely uses only a fraction of their creative abilities at work, often due to workplace structures, routines and expectations that prioritize efficiency over innovation. Studies suggest that although everyone has creative potential, many business owners and employees operate within constraints that limit creative expression.

Using an ultra-powerful laser, researchers have successfully characterised liquid carbon in the lab for the first time. The experiments offer rare insight into one of the most abundant elements in the universe, which, despite its ubiquity, remains the least understood in its liquid form among stable elements.

Late in 2023, a video shared on Reddit that captured a passenger plane flying over San Francisco went viral because it appeared to be levitating mid-air. While some fighter jets can hover in place, there aren't any commercial planes with the technology to do so. What you see in the video is an optical illusion that has more to do with the concept of reference points and motion than any secret hover mode.

Up to now, humans have only been able to observe four dimensions in the universe – height, length, width and time. But beyond these dimensions, collectively known as 'spacetime', there may be more that we cannot perceive – including the fabled fifth dimension.
