While there is more to North Korean cinema than meets the eye, the country’s film industry ultimately amounts to little more than a mouthpiece for the ruling Kim dynasty.
This storm rained electrons, shifted energy from the sun's rays to the magnetosphere, and went unnoticed for a long time.
50% of stars are in Sun-like ‘singlet’ systems. The planetary nebulae we see just don’t line up. Around 7 billion years from now, our Sun’s life will end. As the Sun […]
Even with leap years and long-term planning, our calendar won't be good forever. Here's why, and how to fix it.
Please stop calling our Sun an "average star." It is philosophically dubious and astronomically incorrect.
The idea of "absolute time" was our default for millennia. But time is relative, as gravity and motion both cause time to dilate.
Even at its faintest, Venus always outshines every other star and planet that's visible from Earth, and then some!
If we’re migrating slowly away, is our speed changing, too? Every year, planet Earth completes one revolution around the Sun while spinning on its axis. On a year-to-year basis, our […]
Two aspects of memory – fast updating and long lasting – are typically considered incompatible, yet the insects combined them.
Migrating our planet to a safer orbit might be the only way to preserve Earth after all the ice melts.
It peaks the nights of August 11–13, but it’s no longer the year’s most reliable meteor shower. Every year, beginning in mid-July, planet Earth commences passing through an enormous debris […]
How can you "touch the Sun" if you've always been inside the solar corona, yet will never reach the Sun's photosphere?
The past ~4 billion years have been an incredibly successful, unbroken run for life on Earth. The future won't be nearly so bright.
Leap years will only get us through the next few thousand years before we have to fix it. With every year that passes, we assume that two separate things will both […]
Despite being the closest planet to the Sun, Mercury "only" reaches 800 °F at its hottest. Venus is always hotter, even at night.
Hubble’s still going strong after 31+ years. James Webb will never make it that long. Every decision that’s made — in both astronomy and in life — comes with its own set of pros and […]
The Sun produces a wide variety of particles and radiation throughout it, but all of its neutrinos are produced in the core: where nuclear reactions take place. The various reactions […]
No planet enters retrograde more frequently than Mercury, which does so 3-4 times each year. Here’s the scientific explanation for why.
The new book "Lost Cities, Ancient Tombs" documents 100 archaeological discoveries that changed the world.
