If you’ve been following astronomy headlines, you might have noticed a curious new arrival to the neighborhood: Comet 3I/ATLAS. It’s not just another “regular” comet from the outer solar system–this one’s an interstellar visitor, meaning it was born around another star entirely.

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 ���ӽ紫ý 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.

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.

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.

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.
