A recent General Electric commercial about scientists being treated as celebrities has been getting a lot of attention. In case you've never heard of the scientist in the commercial, her name is Millie Dresselhaus, a trailblazing physicist and mentor. Unfortunately Dresselhaus died on February 20, just weeks after the commercial was released. Millie was so important to so many people that...

In December 1968 Apollo 8 became the first vehicle to circle the Moon with humans onboard. The famous 'Earthrise' picture was taken from that mission. A few moments ago the private company SpaceX announced that they are planning a similar trip nearly 50 years after Apollo 8.

The mission however, is a request from two individuals who are privately paying to be launched on a Falcon heavy lift...

Here is a clever way to think about the detection of the seven Earth-sized planets around the nearby star TRAPPIST-1. A team at Caltech looked at the data collected by NASA's Spitzer Space Telescope and assigned each planet a musical note. Each time a particular planet "transits," or crosses in front of the face of the star, that planet's note is played on a xylophone.

On February 22, 2017, NASA's Spitzer Space Telescope revealed seven Earth-sized planets orbiting a small star just under 40 light-years away. Spitzer was abl...

Back in the 1960s, physicist Geoffrey Chew proposed the bootstrap philosophy: "Chew’s vision of a self-determining universe required that all particles be equally composite and fundamental," Natalie Wolchover writes. "He conjectured that each particle is composed of other particles, and those others are held together by exchanging the first particle in a process that conveys a force. Thus,...

Happy 70th birthday Alan Guth! Born in New Brunswick, New Jersey, Guth studied physics at Princeton and Columbia universities. He originally set out to become a particle theorist, but a lecture by Robert Dicke on the so-called flatness problem in cosmology inspired him to seek a solution. Invoking physics from grand unification theories, Guth proposed in 1981 a way to solve both the flatness...

Winston Churchill is known as a shrewd politician, but he was also a science enthusiast. In a recently recovered 1939 essay, he analyzed the possibility of extraterrestrial life. And Churchill knew his stuff when it came to physics. One profile of Churchill describes a Sunday in April 1926 when "he set aside his papers for the morning and dictated a summary of quantum theory."

Images of the day: Supernova 1987A, 30 years ago and today. The photo on the left was taken by the ESO Schmidt Telescope shortly after the supernova was spotted in February 1987; the bright white light is clearly visible. The photo on the right was taken last month by the Hubble Space Telescope. The supernova remnant is near the center of the image, with a main ring and two auxiliary rings....

A new material may have the cooling effect of an air conditioner without the energy bills. Researchers created a polymer film that absorbs very little sunlight and then radiates heat away at a wavelength that can flow right through the atmosphere as if it weren't there.

On this day 30 years ago, light and neutrinos arrived on Earth from a cataclysmic stellar explosion that took place about 170,000 light-years away. The event, called Supernova 1987A, was the first supernova visible to the naked eye in nearly 400 years. Although the bright light (middle right in the picture) tipped off astronomers to the event, tiny particles called neutrinos actually arrived...

Noticed a lot of stories about a major NASA discovery popping into your news feed? Here's what you need to know: Researchers have discovered that a nearby star is orbited by seven planets, at least six of which are similar in size and mass to Earth. It's the most Earth-sized worlds ever found around a single star. At least some of the planets are probably rocky, and they may be able to support...

Today is the birthday of Friedrich (Fritz) Strassmann, a German physical chemist who, along with Otto Hahn and Lise Meitner, discovered nuclear fission. Together, the three bombarded uranium with neutrons to study the radioactive products that formed. In 1938 Meitner was forced to flee to Sweden because of the anti-Jewish laws being enacted in Nazi Germany. However, she continued to...

On this day in 1947, the founder of Polaroid, Edwin Land (pictured), demonstrated instant photography at a meeting of the Optical Society of America in New York City. The camera contained film for creating negatives and sheets for printing the final picture; in between were chemical reagents that transferred images from film to photograph. Polaroid’s Model 95 camera went on sale the following...
