No planet enters retrograde more frequently than Mercury, which does so 3-4 times each year. Here’s the scientific explanation for why.
And why, even at its faintest, it always outshines every other star and planet. If you’ve been looking to the west after sunset recently, you may have noticed that there’s one […]
The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we're woefully unprepared.
Based on the atoms that they're made out of, the innermost planet should always be the densest. Here's why Earth beats Mercury, hands down.
All across the Universe, planets come in a wide variety of sizes, masses, compositions, and temperatures. And most have rain and snow.
Astronomy's roots rest in the very origins of humanity. We have always looked to the skies for answers. We are starting to get them.
Do you think you know the Solar System? Here's a fact about each planet that might surprise you when you see it!
If there are human-sized creatures walking around on other planets, would we be able to view them directly?
From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
