The data has been taken, collected, and analyzed. So where is the first image of an event horizon, already? Across multiple continents, including Antarctica, an array of radio telescopes observe the […]
The best books, calendar, accessories and more are all just one click away. Every year, there are no shortage of wonderful, exciting, informative gifts you could get for those who matter […]
The Big Bang happened everywhere at once, but stars are a different story. The Universe, back at its inception, was almost perfectly identical everywhere. It was the same high temperature […]
Mars will never look as big as the full Moon. But it isn’t even the biggest planet. From humanity’s perspective, the Sun and Moon always dominate Earth’s skies. The Moon and […]
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, […]
If we don’t invest in learning about the Universe, we aren’t going to learn very much. Every ten years, the field of astronomy and astrophysics undergoes a Decadal Survey. This charts […]
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 […]
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 […]
Japan looks to replace China as the primary source of critical metals
If we ever discover the true size of the universe, we’ll likely have galaxies to thank. The trillions of massive star clusters we’ve observed are sending light from the early universe back to us.

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 […]
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 […]
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: […]
Is it saying too much to say something doesn’t exist when you have no evidence either way?
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.
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. […]
Giving our solar system a “slap in the face.”
Policy advisor Simon Anholt believes the question we should ask is, which country is the “goodest”?
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.
Also known as the “Halloween Comet,” a 2,000-foot-wide asteroid is expected to pass Earth on November 11.
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 […]
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 […]
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 […]
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 […]
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.
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 […]
Everything you wanted to know about black holes, supernova, and quasars but were afraid to ask.
From the inflationary state that preceded the Big Bang to our cold, lonely, dark energy-dominated fate, the Universe goes through six different eras. We’re living in the last one already. The […]
