Without quantum physics, the Sun wouldn’t shine at all. Earth, as we know it, is only teeming with life because of the influence of our Sun. Its light and heat provides […]
The Twin Jet nebula, shown here, is a stunning example of a bipolar preplanetary nebula. At the center, a dying star is in the final stages of life where it […]
Until recently, we were only able to view Venus’s surface with radar or by landing on the planet. It was believed that Venus’s surface was entirely obscured by clouds; NASA’s Parker Solar Probe proved otherwise.
Gamma-ray bursts are among the most energetic cosmic events of all. On October 9, 2022, a remarkable one occurred: the brightest ever seen.
Our temporal experience of the world is not divided into a series of neat segments, yet that’s how we talk about time.
Research from NASA reveals Mars’ spectacular volcanic past.
The mediocrity principle is often used to make claims about the abundance of life across the universe, but these claims are likely unfounded.
Measurements of the acceleration of the universe don’t agree, stumping physicists working to understand the cosmic past and future. A new proposal seeks to better align these estimates — and is likely testable.
Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?
A levitating vehicle might someday explore the moon, asteroids, and other airless planetary surfaces.
New technology is helping physicists move forward in the search for the Theory of Everything.
We still don’t know what dark matter is, but at least we now know what it’s not. When it comes to science, we often say that it only takes a single […]
The Earth is not flat. Here’s how you can prove it.
A new model addresses a longstanding problem: where do quasars get the fuel they need to outshine entire galaxies?
It’s the best-known transcendental number of all-time, and March 14 (3/14 in many countries) is the perfect time to celebrate Pi (π) Day!
The first Earth-sized planet without a parent star has just been discovered. For countless millennia, planets beyond our Solar System were mere speculation. Today, we know of over 4,000 confirmed […]
For the first time, light that comes from behind a black hole has been spotted.
And what can it teach us about our Solar System’s earliest days? In many ways, astronomy is unique among the sciences. In every other field, you have the ability to design […]
Bernini created art for 8 different popes. In the process, he helped reinforce and redefine Christianity’s visual culture.
We’re still not sure what the ultimate question is. Here are 5 excellent candidates. One of the most amusing stories in all of science fiction is Douglas Adams’ The Hitchhiker’s […]
Is the Universe the same everywhere? Or are there truly ‘special places’ around? For practically all of human history, one assumption about our place in the Universe had long gone unchallenged: […]
Shame is a powerful tool that must be used with care.
The study identified superhabitable planets outside of our solar system.
Water is vital for life. Luckily for spacefaring humans, the solar system is full of it.
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
Whether or not life exists elsewhere in the Universe, we can be assured of one thing: We are the only human beings in the cosmos.
You’re gonna die, cloud! All stars, even our Sun, will someday eventually die. After burning on the main sequence for billions of years, the Sun will expand into a red giant, […]
