Galileo is considered one of the greatest astronomers of all time. His discovery of Jupiter’s major moons (Io, Europa, Ganymede and Callisto) revolutionized astronomy and helped speed the acceptance of the Copernican Model of the universe. However, Galileo is also known for the numerous scientific inventions he made…
Jupiter's icy moon Europa is perhaps the most tantalizing destination in our solar system. Scientists have been trying for years to kickstart a mission to Jupiter's most enigmatic moon, with very Earth-like concerns over costs keeping missions grounded until now.
Galileo Galilei has spent the last 300 years giving the finger to the universe via a glass case in a museum. And that's one of the less weird fates for his body parts.
Europa, Jupiter's sixth-closest moon, has long been a source of fascination and wonder for astronomers. Not only is it unique amongst its Jovian peers for having a smooth, ice-covered surface, but it is believed that warm, ocean waters exist beneath that crust – which also makes it a strong candidate for …
Our moon missions have served a variety of purposes ranging from technical ones to the satisfaction of our curiosity. But the moon has also served one very practical and immediate purpose: It's a laboratory. Here's a history of how we've used the moon as a scientific facility — and how we might do it in the future.
Here's a simple problem, illustrated simply, that will have you cocking your head and wondering how it's done. You won't be the first. Aristotle (reputedly) first took a whack at this, and Galileo gave it a try as well. See what you can make of it.
We know that the Catholic church has a troubled history with the idea of heliocentrism, but when did this history become history? What year would Galileo have gotten away with publishing his book?
We're loving this expertly animated history lesson in physics from the folks at BBC Science Club. Directed by Åsa Lucander and narrated by Dara O Briain, the short provides a tidy, witty and informative overview of scientists and scientific progress from Galileo right up through the Large Hadron Collider.
We've all heard stories about killers in the back seat and puppies that turn out to be rats, but hapless heroines aren't the only ones who spawn urban legends. There are a number of urban legends about famous scientists. Some are funny, some are mere inaccuracies, and some are about committing murder by accident.
We think it's obvious that the Earth goes around the sun, today, but back before Copernicus, detractors had the most obvious argument possible against heliocentrism. To combat this, in his argument in favor of a sun-centered universe, Galileo came up with a thought experiment about relativity now known as Galileo's…
In observance of India's National Science Day, graphic designer Kapil Bhagat created a series of simple typographical posters that creatively recognize scientists for their various inventions or discoveries.
Scientific discovery may require reason, rationality, and a firm handle on the facts, but science history has its share of myths, urban legends, and tall tales. Thought experiments are misinterpreted as real experiments; the scientist with the most interesting story gets the credit for a discovery; misunderstandings…
Not Saturn. Jupiter. Yes, Jupiter has rings. Did we just blow your mind?
Science is a dangerous business, full of risky propositions and strange experiments. And sometimes, scientists wind up going to jail for their pains. Some of them for the integrity of science, and some for far more sordid reasons.
Feast your eyes on the volcano-covered surface of Io, the innermost of Jupiter's four Galilean moons.
Remember when the Church got all up in Galileo's grill for challenging the geocentric interpretation of the Universe? Seeing this almost makes you wonder if the Universe is still a little sore about that.
The equivalence principle is one of the fundamental concepts behind gravitational theory and general relativity, and holds that gravity exerts the same force on objects of different mass.
A week ago, who among us would have guessed that light, the universe's ultimate speed demon, would be observed getting outpaced by a bunch of reckless neutrinos? Yes, these observations will obviously need to be checked and rechecked, but it just goes to show that you rarely know as much about something as you think…
Galileo was facing some stiff odds when he published his Dialogue Concerning the Two Chief Systems of the World. He'd already been officially warned against heliocentrism, and he had enemies. But it's possible, just possible, that he would have squeaked by if he hadn't been a jerk to the Pope.
