Once every 12 years, Earth, Jupiter, Uranus, and Neptune all line up, opening a window for a joint mission. Our next chance arrives in 2034.
Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity.
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.
Gravitational waves are the last signatures that are emitted by merging black holes. What happens when these two phenomena meet in space?
Some think the reason fundamental scientific revolutions are so rare is because of groupthink. It’s not; it’s hard to mess with success.
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.
On Saturday, October 14, a solar eclipse crosses North and South America. Here are 4 quick, easy, low-tech activities for everyone to enjoy!
In logic, ‘reductio ad absurdum’ shows how flawed arguments fall apart. Our absurd Universe, however, often defies our intuitive reasoning.
Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.
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.
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.
A deep dive into the chaotic journey of star formation.
Time is relative, not absolute, as gravity and motion both cause time to dilate. Your head and feet, therefore, don’t age at the same rate.
Carl Sagan was far from the first to declare we are the children of ancient stars.
To know how to protect its astronauts, NASA needs to first understand the threat.
2023 is an exciting time for the study of quark-gluon plasmas.
Matter is made up largely of atoms, where atomic nuclei can contain up to 100 protons or more. But how were the heaviest elements made?
The long-elusive neutrino was shown to have a bizarre property no one expected: mass. New, tightest-ever limits have profound implications.
Want to avoid getting “spaghettified” by a black hole? Steer clear of the smaller ones.
There’s an old saying that “what you see is what you get.” When it comes to the Universe, however, there’s often more to the full story.
“We are all in orbit around the center of the Milky Way galaxy. How big is this collection of stars? Somewhere between 200 and 400 billion suns in the Milky Way galaxy, about 100,000 light years across.”

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.
A recent paper in the journal Physical Review Letters claims to prove that a “kugelblitz” is not possible.
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?
Life became a possibility in the Universe as soon as the raw ingredients were present. But living, inhabited worlds required a bit more.
Australia’s AAPowerLink boasts three global superlatives: largest solar farm, largest battery, and longest power cable.
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.
A look back at the rise of solar power in the US and what’s next.
Life might be more common across the Universe than the “Hard Steps Model” suggests.
