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.

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.

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

In two weeks' time, the European Southern Observatory (ESO) is going to present the world with new information about our Milky Way.

In a strange corner of our solar system live two alien blobs. With sprawling, amorphous bodies the size of continents, these oddities are thought to spend their time lying in wait for their food to rain down upon them – then simply absorbing it.

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.

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

Out in the dark depths of space, our models of the Universe get messy. A new study looking at the ultra-diffuse dwarf galaxy AGC 114905 has revived a controversial theory (or more accurately a hypothesis) of gravity, and given us more questions than answers about what's making our galaxies tick.

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.

After nearly 13.8 billion years of nonstop expansion, the universe could soon grind to a standstill, then slowly start to contract, new research published in the journal Proceedings of the National Academy of Sciences suggests.

It's an amalgam of "hologram" and "teleportation," and though it may seem like it, it isn't just a niche Sci-Fi term buried somewhere in Isaac Asimov novels and Star Trek episodes. In October, NASA used this mind-boggling, futuristic mechanism to bring NASA flight surgeon Dr.

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

For the past couple of years, I’ve been working with researchers in northern Greece who are farming metal.

If you are going to look for evidence of technologically advanced civilizations in the Universe, you must start by considering what, exactly, you might be looking for. My colleagues and I in the NASA-sponsored Categorizing Atmospheric Technosignatures program spend a lot of time thinking about this.

Researchers of synthetic biology based at the Massachusetts Institute of Technology (MIT) in the US have devised a system to protect the gut microbiome from the effects of antibiotics.
