If space were really curved due to matter and energy, we should see light deflect. A solar eclipse provides the perfect opportunity. “Eddington had needed to make significant corrections to […]
Now we know, on every scale. “There is no such thing as perpetual tranquillity of mind while we live here; because life itself is but motion, and can never be without […]
How a telescope 100 times the size of Hubble is going to change everything. “For my confirmation, I didn’t get a watch and my first pair of long pants, like […]
Jupiter’s icy moon, Europa, may spout water vapor miles into space, says NASA, making it possible to better determine whether its vast underwater oceans support extraterrestrial life.
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 […]
Astrobiologist Lewis Dartnell explains why we shouldn’t be afraid of alien visitors.
It’s the longest feast we’ve ever seen, and it’s still going on! But why? “Put two ships in the open sea, without wind or tide, and, at last, they will come […]
Last week, Cassini plunged into Saturn’s atmosphere. Here are the top 6 things we learned from it while it was alive. “Being a scientist and staring immensity and eternity in the […]
Why are we so hung up on Pluto’s planetary status? Astrophysicist Neil deGrasse Tyson urges us to get over it already!
Could there be a massive, giant planet beyond Neptune? Here’s what the science says… for now. “Finding out that something you have just discovered is considered all but impossible is one […]
Life may not be a rarity after all, but the result of a certain set of conditions.
With off-the-shelf materials and a little dry ice, you can discover particles that wouldn’t exist unless relativity were real. “The experiments that we will do with the LHC [Large Hadron Collider] […]
Churchill displays a surprising amount of knowledge on a question that we are still wrestling with.
You’ve never seen a rogue planet like this. “Other galaxies like Andromeda are shooting these ‘spitballs’ at us all the time.” –James Guillochon, coauthor on the new study Black holes don’t […]
Have you heard that life is unlikely around low-mass, red dwarf stars? It might be time to rethink that flawed conclusion. “Laws of nature mixed with evolutionary/historical contingencies allow for […]
The red planet once wasn’t so different from Earth. Here’s what happened. “Mars’ atmosphere is so thin, you do not need a lot of streamlining. By the time the ship […]
I’ll meet you at the corner of Saruman and Aragorn
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?
A massive chart of humankind’s 113 spacecraft so far and where they’ve gone.
But that’s okay; the most likely world for life may not be like Earth, after all. “You can spend too much time wondering which of identical twins is the more alike.” […]
Astrophysicists have been looking for worlds like Proxima b since the 19th century. At last, they’re found! This article is contributed by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
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.
Three simple questions; an amazing story that goes way beyond Einstein! “Each ray of light moves in the coordinate system ‘at rest’ with the definite, constant velocity V independent of […]
That’s not how probability works. Or asteroids, for that matter. “Bringing an asteroid back to Earth? What’s that have to do with space exploration? If we were moving outward from there, […]
Peel off your tin-foil hat like a Hershey’s Kiss, because Bill Nye has a reality check for the alien conspiracy theorists out there.

And could what we see over there spell disaster for Earth? “An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered […]
If you gazed up at the Perseids, you’ll want to appreciate the fact that we’re still here. “Honestly, if you’re given the choice between Armageddon or tea, you don’t say ‘what […]
Think Saturn is the only ringed world? The story is far better than that! “The phenomena of nature, especially those that fall under the inspection of the astronomer, are to be […]
According to Elon Musk, it’ll only take between 40 and 100 years to achieve a fully self-sustaining civilization on Mars. Here’s how.
