Hubble, our greatest space-based observatory today, is just the beginning. The Hubble Space Telescope has been astronomy’s most revolutionary observatory in history. The stars and galaxies we see today didn’t […]
When it comes to predicting the energy of empty space, the two leading theories disagree by a factor of 100 googol quintillion.
No matter how you define the end, including the demise of humanity, all life, or even the planet itself, our ultimate destruction awaits.
In revolutionary Russia, a group of forward-thinking philosophers offered an alternative to both futurism and communism.
How do physicists solve a problem like entropy?
From physics and alchemy to theology and eschatology, Isaac Newton’s research was rooted in a personal pursuit of the Divine.
All of the matter and radiation we measure today originated in a hot Big Bang long ago. The Universe was never empty, not even before that.
Earth wasn't created until more than 9 billion years after the Big Bang. In some lucky places, life could have arisen almost right away.
It may be time for a cosmological paradigm shift.
A new study says the reason cave paintings are in such remote caverns was the artists' search for transcendence.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
From ancient Greek cosmology to today's mysteries of dark matter and dark energy, explore the relentless quest to understand the Universe's invisible forces.
The ancient Greeks were obsessed with geometry, which may have formed the basis of their philosophical cosmology.
Dr. Tyson explains where we might find aliens, why "dark matter" is a misleading term, and why you can blame physics for your favorite team's loss.
Shortly after planet Earth formed, life took a permanent hold on our surface. But just how common is such an outcome?
When the Universe was first born, the ingredients necessary for life were nowhere to be found. Only our "lucky stars" enabled our existence.
If your computer crashes, it might be due to a star that exploded somewhere in the Universe millions of years ago.
Thanks to a couple of rovers, we know Mars was once blue.
There are plenty of life-friendly stellar systems in the Universe today. But at some point in the far future, life's final extinction will occur.
This short story is a fictional account of two very real people — Anaximander and Anaximenes, two ancient Greeks who tried to make sense of the universe.
From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.
Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity.
Explanations for the cosmic speed limit often conflate mass with inertia.
Hubble showed us what our modern day Universe looks like. JWST's big goal was to teach us how the Universe grew up. Here's where we are now.
The "first cause" problem may forever remain unsolved, as it doesn’t fit with the way we do science.
From Taoism to hedonism, philosophers have devised all sorts of ways to live your best life.
In the infant Universe, particle physics reigned supreme.
We have become the greatest threat to ourselves and to life on this planet. We need a set of agreed-upon safeguards to preserve our future.
Finding out how the Universe grew up was the biggest science goal of JWST. This ultra-early proto-galaxy cluster is one amazing discovery.
