Earth day may have been last week, but the lessons we learned about Earth from space are with us always. “We are not learning to view ourselves as an advanced, evolving […]

Comet-like tail, X-rays and more discovered at Solar System’s edge. “Maybe some people don’t feel scared when they think about comets and supernovas. Maybe they think it is wonderful.” –Lydia Netzer […]
The most distant world ever imaged by fly-by reveals a richer terrain than anyone ever expected. “The cosmic game changed forever in 1992. Before then, logic told us that there […]
There are strict scientific standards a new ‘claimed discovery’ needs to meet. Has cold fusion gotten there? “Between cold fusion and respectable science there is virtually no communication at all. …because the […]
There’s a small rock orbiting our planet more distant than the Moon we know. Does that mean we have two Moons? “You can be the Moon and still be jealous of […]
Looking into the great, dark unknown was a mystery for thousands of years. No longer! “Science cannot tell theology how to construct a doctrine of creation, but you can’t construct a […]
The search for Planet Nine is on. The problem is scientists don’t know where to start — it has an orbit of 10,000 to 20,000 years. However, a group of researchers from France may have narrowed the search area.
The periodic table offers up so many possibilities, but some things are off-limits in our Solar System. “There’s no god, it’s the elements that control this world and everything on it.” […]
The first of the three great NASA disasters — Apollo 1, Challenger and Columbia — happened 49 years ago. Look back. “If we die, we want people to accept it. We’re in a risky business, […]
By devising the first truly brilliant physics experiment, Galileo gave us the equations of motion we still use today. “All truths are easy to understand once they are discovered; the point […]
Star Wars’ Hoth has nothing on the real-life version! “My Lord, the fleet has moved out of lightspeed. Com Scan has detected an energy field protecting an area of the […]
Looks like the inner planets formed *after* the gas giants moved to their current position, and Jupiter ejected a fifth giant, too! “The stars look the same from night to […]
It took hundreds of years for Einstein to dethrone him, and even then, he was off by less than 1% of a spectacular prediction.
The most spectacular satellite system of any known planet, Saturn’s Rings are a sight like no other. “This then, I thought, as I looked round about me, is the representation […]
Hint: it doesn’t have anything to do with our blue skies. “Whenever I gaze up at the moon, I feel like I’m on a time machine. I am back to that […]
Planet Nine? More like “Planet maybe.” “Finding out that something you have just discovered is considered all but impossible is one of the joys of science.” –Mike Brown Last week, the […]
Once a complete mystery, the Cassini mission has solved them at last! “It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what […]
Dark matter may be cold and collisionless, but the strange behavior of planets just might lead to its detection. “Few enterprises of great labor or hazard would be undertaken if […]
While a “counter-Earth” may be impossible, there are three other ways it could actually work out. “We are not like the social insects. They have only the one way of doing […]
Are comets and asteroids periodic, and are we due? “Biological diversity is messy. It walks, it crawls, it swims, it swoops, it buzzes. But extinction is silent, and it has no […]
It’s said to be the majority of matter in the Universe, but how sure are we of that? “For the moment we might very well call them DUNNOS (for Dark Unknown […]
An incredible live-blog of an incredible event. “It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new […]
If energy is always conserved, then what “gains” the energy that photons lose as the Universe expands? “…in every kind of chemical change no loss of matter occurs […] in all […]
If you see a picture of a planet, can you identify which of the eight it is? “Don’t go around saying the world owes you a living. The world owes […]
And the method teaches us just how far Pluto is from actual planethood. “Some kind of celestial event. No — no words. No words to describe it. Poetry! They should have sent […]
Four billion years ago, the Universe was a different place. What would we have seen? “In such moments, offering up his heart at the hour when the flowers of night […]
Only 0.1% of all stars will die in a type II supernova. This one’s running away so fast, it’s literally a “shocking” sight. “The thing is, when you see your […]
And it couldn’t have done it without the heat from our world. “Cheap little rhymesA cheap little tuneAre sometimes as dangerousAs a sliver of the moon.” –Langston Hughes If you’ve ever […]
And is blue even a rare color for planets? “Whenever I gaze up at the moon, I feel like I’m on a time machine. I am back to that precious […]
