A microwave radiometer onboard the Juno spacecraft orbiting Jupiter could soon reveal where and how the giant planet formed
Juno team member William Kurth offers an exclusive tour of the instruments the spacecraft will use to study Jupiter's intense magnetic waves. Produced with support from Explore Scientific
After a do-or-die engine burn the second spacecraft ever to orbit Jupiter is preparing to revolutionize our view of the giant planet
In this exclusive interview the project manager of one of Juno's instruments explains how the spacecraft will slow down prior to its insertion into Jupiter's orbit.
Poised to enter Jovian orbit on July 4, the NASA spacecraft is set to probe the gas giant’s deepest mysteries
Our sense of the universe as an orderly expanse where events happen in absolute locations is an illusion
Einstein's assertion that God does not play dice with the universe has been misinterpreted
High-resolution images of the icy worlds reveal towering mountains, yawning canyons and perhaps hints of a subsurface ocean
Though the dwarf planet is now behind it, the spacecraft’s science returns are only just beginning
Physicists can't seem to find the time—literally. Can philosophers help?
Could time end? Yes. And no. Recent work in physics suggests a resolution to the paradox
Theoretical physicist Carlo Rovelli, one of the creators of loop quantum gravity, and his collaborator Hal Haggard have just come out with a new paper on black holes.
Physicists Think They Can Solve the Mysteries of Quantum Mechanics, Cosmology, and Black Holes in One Go [Guest Post]
It’s lucky that debates over the meaning of quantum mechanics are so entertaining, because they seem to go on forever. The sundry proposed interpretations make the same experimental predictions, so many people fret that there’ll never be a way to decide among them.
In 1954 the renowned physicist Enrico Fermi did a simple but depressing calculation about future particle accelerators. To create particles with an energy of 3 teraelectron-volts, he estimated, you’d have to build a ring 8,000 kilometers in radius at a cost of $170 billion.
Last year I got talking to theoretical physicist Aron Wall about the thermodynamics of quantum gravity. Now that's a deceptively beautiful phrase: in four words, you get three of the deepest areas in modern science.
In our February issue, Scientific American had an article on the phenomenon of liquid-rope coiling--the way that viscous fluids curl as they fall onto a surface, forming what looks like a miniature basket.
Gravitational Waves Reveal the Universe before the Big Bang: An Interview with Physicist Gabriele Veneziano
It’s not usually put like this, but the discovery of primordial gravitational waves two weeks ago has given us our first direct glimpse of a period before the big bang.
The first sighting of the light spectacle on another planet reveals properties of the mysterious Venusian clouds
Last night I had the pleasure of going to Amanda Gefters book party, celebrating the release of Trespassing on Einsteins Lawn. I first got to know Gefter a decade ago when she audaciously contacted Sci Am to pitch her first-ever science story, and I followed her later career at New Scientist with admiration.
Two weeks ago, I blogged about David Bohm’s interpretation of quantum mechanics. Like Einstein and Louis de Broglie before him, Bohm argued that quantum randomness is not intrinsic to nature, but reflects our ignorance of a deeper level of reality.
