Put two grapes close together in a microwave and you’ll get an electrifying result, all because of the physics of plasmas.
Without a little help from Einstein, we couldn’t have made this discovery. NASA’s Hubble Space Telescope, currently celebrating its 30th anniversary, still churns out novel discoveries. The Hubble eXtreme Deep […]
Map shows oldest buildings for each U.S. state – but also hints at what’s missing.
Artifacts uncovered in southeast Asia offer clues on early complex human cultures.
Telescopes from the ground are bigger, but have to fight the atmosphere. Here’s how to win. In astronomy, seeing farther and fainter than ever before requires three simultaneous approaches. First light, […]
No matter how accurately you place two Plinko chips, you cannot count on the same outcome twice. Of all the pricing games on the iconic television show The Price Is Right, […]
No matter how your year went, Hubble’s views of the Universe never disappoint. Year after year, Hubble’s telescopic views are unparalleled. Saturn, its rings, and 5 of its moons are […]
Passion makes challenges enjoyable, but it may have little use in schools.
Even physicists sometimes fall for these. For centuries, the laws of physics seemed completely deterministic. If you knew where every particle was, how fast it was moving, and what the forces […]
For the cosmos, it’s all too easy being green. Stars come in a wide variety of colors, but never green. Stars form in a wide variety of sizes, colors and masses, […]
Affordable and useful items that will make any trip go more smoothly.
You’re always in control of your breath.
By the end of the decade, we may discover one million black holes. A large enough mass in a compact volume inevitably forms a black hole. Both inside and outside the […]
What can the beauty of autumn’s colors teach us about mortality?
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever. The ultimate goal of physics is to accurately describe, as precisely […]
It comes from a supernova seen just 33 years ago, and it doesn’t pulse. 33 years ago, a supernova occurred just 168,000 light-years from Earth. This new image of the supernova […]
The dream of zero resistance is closer than you may think. One of the biggest physical problems in modern society is resistance. Not political or social resistance, mind you, but electrical […]
‘Fast Optical Bursts’ will confound ground-based astronomy. As of 2021, planet Earth is currently experiencing the least pristine night sky in recorded history. Prior to the development of artificial lighting, […]
From STEM kits to fashion dolls, these creations all came from the minds of female inventors and designers.
Maybe 100% of stars don’t have planets, after all. When stars form in the Universe, they’re created in giant bursts. A stellar nursery in the Large Magellanic Cloud, a satellite galaxy […]
A gift guide of the hottest educational toys for your budding scientist, engineer, or mathematician.
Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]
‘Critical Tourist Map of Oslo’ offers uniquely dark perspective on Norway’s capital.
A 71% wet Mars would have two major land masses and one giant ‘Medimartian Sea.’
We’ve come fantastically far in our understanding of the distant Universe. Here’s how we’ll go even farther. Sometime in 2021, NASA’s James Webb Space Telescope will launch, deploy, and begin science […]
Planets are either rocky, like Earth, or gas-rich, like Neptune, with no in-between. What are the different types of planets that exist in the Universe? If all you could see […]
