Voyager 1 is nearly 14.5 billion miles from Earth and continues to hurtle out of the solar system at about 38,000 miles per hour.

And the adventures scientists go on to better understand our enigmatic seas. The Earth is mainly a water world — more than 70 percent of its surface is covered by oceans — and yet we know so little about what resides beneath the waves.

As a physicist working at the Large Hadron Collider (LHC) at CERN, one of the most frequent questions I am asked is, “When are you going to find something?” Resisting the temptation to sarcastically reply, “Aside from the Higgs boson, which won the Nobel Prize, and a whole slew of new composit

Sometimes it takes an animation on Twitter to truly comprehend – or at least begin to comprehend – the amazing diversity of worlds making up our Solar System. Enter planetary astronomer James O'Donoghue from the Japan Aerospace Exploration Agency (JAXA).

We’ve been capturing space-based images of Earth for nearly three-quarters of a century, but these eight views of Earth are each profound in their own way.

Could our universe have been created in a petri dish? Avi Loeb seems to think so. The Harvard astronomer posits that a higher “class” of civilization may have conjured up our universe in a laboratory far, far away.

Since the discovery of gigantic, ancient dinosaurs, scientists have struggled with the question: what made them go away? The prevailing theory is that they were wiped out by asteroid impact, though there are alternative theories that a string of volcanic eruptions suffocated the planet, making it un

The crystal structure of a layer of graphyne. Credit: Yiming Hu For over a decade, scientists have attempted to synthesize a new form of carbon called graphyne with limited success. That endeavor is now at an end, though, thanks to new research from the University of Colorado Boulder.

The achievement of powered flight on another world is one of the great spaceflight feats of the last decade.

As plastic waste proliferates around the world, an essential question remains unanswered: What harm, if any, does it cause to human health? A few years ago, as microplastics began turning up in the guts of fish and shellfish, the concern was focused on the safety of seafood.

By resolving a paradox about light in a box, researchers hope to clarify the concept of energy in quantum theory. The quantum physicists Sandu Popescu, Yakir Aharonov and Daniel Rohrlich have been troubled by the same scenario for three decades.

Our species faces a pivotal moment in human history. Either we develop the technology to safely harness the energy needed to escape our planet, or we kill ourselves in some great cataclysm, a stark new study claims.

China's Zhurong rover has found evidence suggesting that water persisted on Mars for much longer than expected.

Does time exist? The answer to this question may seem obvious: of course it does! Just look at a calendar or a clock. But developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously.

The Universe is so huge, and the worlds within it so numerous, that it seems like anything is possible. But the laws of physics and chemistry are the same everywhere.
