An extremely rare collision of massive subatomic particles could reveal the nuts and bolts of how the subatomic particles called Higgs bosons impart mass to other particles.
The Higgs boson particle, which was detected for the first time in 2012, is essentially tossed around like a ball between two …
The biggest building boom in the history of astronomy is upon us. In Chile and Hawaii and in space, astronomers are getting powerful telescopes that …Astronomy
The future, it is often said, belongs to those who plan for it. And astronomers have been busy working the proverbial smoke-filled rooms (or whatever passes for them today) where the destiny of big science is often shaped and crisscrossing one another in airports on fund-raising trips. Now they are …Astronomy
For centuries people have found meaning — or thought they did — in what they could see in the sky, the shapes of the constellations echoing old myths, the sudden feathery intrusion of comets, the regular dances of the planets, the chains of galaxies, spanning unfathomable distances of time and …Universe

Europa is like a spherical ice cube that has partially melted. In fact, if you shook this small moon of Jupiter, you might hear a sloshing sound.
That’s because a deep, global ocean lies beneath the moon’s frozen, criss-crossed crust – an ocean that might be as much as 100 kilometers deep. In fact, …Cool Stuff
