The reports that our Solar System is missing the galaxy’s most common type of planet are greatly exaggerated. “To raise new questions, new possibilities, to regard old problems from a […]
Might Armageddon come not from an asteroid or a comet, but by something completely unseen altogether? “Honestly, if you’re given the choice between Armageddon or tea, you don’t say ‘what […]
We might have been spared the worst of Hurricane Matthew, but the underlying science is informative at any time! “She didn’t even know what she’d do when she got back to […]
The dark horsehead nebula isn’t dark at all, but only if you look at the invisible forms of light. “If you are fearful, a horse will back off. If you are […]
Scientists produce a value for the cosmic microwave background that will definitely prove or disprove that the speed of light used to be higher.
As great as Hubble is, it can only see a narrow range of light, which means it can only see a sliver of the Universe. Want more? “We conducted the first […]
Either momentum truly is conserved and this isn’t a reactionless drive… or else. “The law of the conservation of momentum is the basis of the static thrust equation, the law of […]
Scientists discover unusual galaxies that raise questions about Einstein’s theory of gravity and the existence of dark matter.
There’s useful science to be gotten out of it, but most science that mentions it is anything but. “There is a voice inside of youThat whispers all day long,‘I feel this […]
What narrow misses did NASA’s Juno probe face on the five-year journey to Jupiter, and it’s acrobatic slip into the orbit of our solar system’s largest planet?
https://players.brightcove.net/2097119709001/4kXWOFbfYx_default/index.html?videoId=5093427476001 In 1946, we made history by photographing the Earth from space for the first time. How far we’ve come! “You develop an instant global consciousness, a people orientation, an […]
After nearly 20 years in orbit around Saturn, Cassini prepares to say goodbye. “All the atoms of our bodies will be blown into space in the disintegration of the solar system, […]
But that doesn’t mean it actually works as advertised. “All of the books in the world contain no more information than is broadcast as video in a single large American […]
What kind of person could withstand a trip to Mars and back? NASA and Hi-SEAS is trying to find out.
Something isn’t right about the Universe without something extra. So why can’t scientists agree on what that “extra” thing is? “All we know so far is what doesn’t work.” –Richard Feynman […]
Why are we so hung up on Pluto’s planetary status? Astrophysicist Neil deGrasse Tyson urges us to get over it already!
How many galaxies are there in the observable Universe? For the first time, we don’t just have a ‘lower limit’ — we have an answer. “Our posturings, our imagined self-importance, the delusion that […]
With gift ideas from as little as $11, there might be something to tickle anyone’s fancy. “It is worthy of notice that in Table VI the brighter variables have the longer […]
An astronomer thinks he sees the next red nova about to happen, and when.
It seems inevitable that there will be a Mars colony, but the path there won’t be easy. There are two key challenges ahead that will push innovation.
How we know some galaxies have more than others. “Motions of the stars tell you how much matter there is. They don’t care what form the matter is, they just tell […]
Life may not be a rarity after all, but the result of a certain set of conditions.
And what are our prospects for observing its event horizon? “Never look down to test the ground before taking your next step; only he who keeps his eye fixed on the […]
The way to greatness requires us to look forwards, not backwards. “Whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, […]
They move at the speed of light, but not even light can escape. So how do gravitational waves? “I think there are a number of experiments that are thinking about […]
Our Moon might even be a rarer occurrence for a Solar System than an ‘Earth’ is. “The pressure to compete, the fear somebody else will make the splash first, creates a […]
Carl Sagan was one of the people who helped shape this recording that might just end up in the hands of some other beings, somewhere out there.
When the next big solar flare comes for Earth, will we be ready? “Concentrate all your thoughts upon the work at hand. The sun’s rays do not burn until brought to […]
