In ~7 billion years, our Sun will run out of fuel and die. So will every star, eventually. Here are the different fates they’ll encounter.

In the early stages of our Solar System, there were three life-friendly planets: Venus, Earth, and Mars. Only Earth thrived. Here’s why.

On June 20, 2024, the summer solstice occurs at its earliest moment since 1796: when George Washington was President of the USA. Here’s why.

Earth, the only rocky planet with a large, massive satellite, is greatly affected by the Moon. Destroying it would cause 7 major changes.

Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity.

The 5th brightest star in our night sky is young, blue, and apparently devoid of massive planets. New JWST observations deepen the mystery.

Total eclipses are a product of a strange and almost eerie cosmic coincidence — one that makes Earth an even rarer world in the galaxy and, by proxy, in the Universe.

The first stars took tens or even hundreds of millions of years to form, and then died in the cosmic blink of an eye. Here’s how.

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.

Leap day only comes once every four years, including in 2024. But the reason we have it, including when we do and don’t, may surprise you.

Mars and Earth were sister planets in many ways, with early similar conditions. Why did Mars die? The leading explanation isn’t universal.

Sun-like stars live for around 10 billion years, but our Universe is only 13.8 billion years old. So what’s the maximum lifetime for a star?

The Michelson-Morley experiment of 1887, despite expectations, revealed a null result: no effect. The implications were revolutionary.

In logic, ‘reductio ad absurdum’ shows how flawed arguments fall apart. Our absurd Universe, however, often defies our intuitive reasoning.

Though Sun Tzu’s “The Art of War” is a classic military treatise, its advice applies to all manner of conflict.

Some think the reason fundamental scientific revolutions are so rare is because of groupthink. It’s not; it’s hard to mess with success.

A deep dive into the chaotic journey of star formation.

Want to avoid getting “spaghettified” by a black hole? Steer clear of the smaller ones.

The race to find dark matter could grow more complex with high-energy neutrino interference.

Due to chaos, it was long thought that planets couldn’t stably orbit systems containing three stars. GW Orionis is the first counterexample.

Although we still don’t know the question, we know that the answer to life, the Universe, and everything is 42. Here are 5 possibilities.

Most of us have heard that the Sun is an ordinary, typical, unremarkable star. But science shows we’re actually anything but average.

Before Constantine received his history-defining vision, a pagan Sun god paved the way for Jesus Christ’s triumphal entry into the Eternal City.

Peaking on the night of August 11/12, up to 100 bright meteors per hour will be visible. Here’s how to make the most of it.

Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn’t instant.

Recasting the iconic Carrington Event as just one of many superstorms in Earth’s past, scientists reveal the potential for even more massive eruptions from the sun.

The closest known star that will soon undergo a core-collapse supernova is Betelgeuse, just 640 light-years away. Here’s what we’ll observe.

Massive objects like black holes, stars, and rogue planets routinely pass near our Solar System. An ensuing comet storm could destroy us.

Until the Apollo missions, we had no idea how the moon got here, just a series of educated guesses. They rewrote the story of the moon’s origins.

To know how to protect its astronauts, NASA needs to first understand the threat.
