It’s a problem that we still haven’t solved, and it spells doom for all of our low-Earth orbiting satellites, even today. On October 4th, 1957, the Soviet Union launched Sputnik 1, […]

A new set of images from NASA’s Chandra X-ray observatory shows us what we’ve never seen before. The Pillars of Creation, 7,000 light years away in the Eagle Nebula, represents one […]
When people learn the Universe is expanding, they want to know where the center is. The ‘answer’ isn’t what they expect. There are two things that people learn about the Universe […]
We aren’t lunarly exclusive. Earth has a few minimoons whizzing around us, including one that comes back into our orbit every 20 years or so.
Respected Oxford mathematician Roger Penrose sees swirls of radioactivity in a sky map as evidence that the Big Bang isn’t true. These “Hawking rings” suggest to him that the universe expands and collapses over and over.
Japan looks to replace China as the primary source of critical metals
Before we formed stars, atoms, elements, or even got rid of our antimatter, the Big Bang made neutrinos. And we found them. The idea of the Big Bang has captivated the […]
Also known as the “Halloween Comet,” a 2,000-foot-wide asteroid is expected to pass Earth on November 11.
A color you’ll never find in a star is responsible for the universal color of star-forming regions. If you look through a telescope’s eyepiece, distant galaxies always appears white. Spiral-shaped […]
We can’t help but wonder if it’s habitable, or even inhabited, but the evidence isn’t there for it. Every star that fills the night sky carries along with it one of […]
Giving our solar system a “slap in the face.”
Gazing upon the red, blood Moon during totality is only part of the wonders awaiting you. On July 27, 2018, the longest total lunar eclipse of the century took place. Totality […]
No, it won’t be as big as the moon, as some have claimed. Still, it will be a nice show for the next month or so.
Everything you wanted to know about black holes, supernova, and quasars but were afraid to ask.
If you think nothing can move faster than light, check out this clever way to defeat that limit. Nothing can move faster than the speed of light. When Einstein set forth […]
Is it saying too much to say something doesn’t exist when you have no evidence either way?
Any hypothesis, no matter how alluring, must be confronted with the full suite of data. Our Solar System may be the closest part of the Universe to us as we look […]
The summer solstice is the longest day of the year, but doesn’t have the earliest sunrise or the latest sunset. Here’s why. The length of a day on planet Earth might […]
13.8 billion years isn’t close to enough time, but if we wait long enough, even our Sun will become one. The Big Bang happened approximately 13.8 billion years ago, and it […]
Scientists just discovered 12 new moons orbiting the planet Jupiter, and they’re… interesting.
Policy advisor Simon Anholt believes the question we should ask is, which country is the “goodest”?
Not only can’t astronomers and planetary scientists agree, but the IAU made it worse for everyone. If you were alive in 2006, you likely remember a momentous event in astronomy: […]
It took more than 9 billion years for Earth to form: the only known planet housing life. But it could have happened much, much sooner. The cosmic story that unfolded following […]
With an assist from Einstein’s gravity and the power of the Hubble Space Telescope, it’s the brightest quasar we’ve ever discovered. In astronomy, there are two types of questions to […]
Our Universe cannot be described by normal matter alone. Vera Rubin’s work led the way. Ask an astrophysicist what our Universe is made of, and you’ll likely receive a shocking surprise. […]
Signals from rare black hole-neutron star pairs could pinpoint rate at which universe is growing, researchers say.
The quest to find another Earth may be in vain.
When two different techniques give two different results, either someone is wrong, or something incredible is happening. Imagine you were a scientist attempting to measure some property of the Universe. […]
