Noted Princeton University physicist Philip Anderson celebrated his 90th birthday at a weekend workshop devoted to an illustrious career that included a Nobel Prize and contributions to understanding the fundamental nature of materials — from everyday items such as magnets to exotic superconductors and new forms of matter.
Indara Suarez didn't speak a word of English when she arrived to the U.S. from Mexico at age 12. The grades she made in high school weren't good enough to get her into a four-year university.
In the fable of the town and country mice, the country mouse visits his city-dwelling cousin to discover a world of opulence. In the early cosmos, billions of years ago, galaxies resided in the equivalent of urban or country environments. Those that dwelled in crowded areas called clusters also experienced a kind of opulence, with lots of cold gas, or fuel, for making stars.
Searching for periodic transits in hundred of thousand of stars was the primary goal of the Kepler space telescope. More than 3500 of such periodic transits were found during the 4 years of the mission. However, not all the planets located in the Kepler field-of-view are transiting their host star. Indeed, if their orbital plane is slightly misaligned (only a few degrees is enough) with the line of sight from the Earth, the planet is not transiting and thus, is “unseen” from the Kepler spacecraft.
The Centre for Quantum Technologies was yesterday honoured with a visit by the Prime Minister of Singapore, Lee Hsien Loong.
In contrast to its apparent simplicity (that brought Einstein his Nobel Prize), the photoelectric effect, when an electron is knocked out from its parent atom by a photon, is quite complicated to analyze in general, especially when the atom contains a large number of electrons.
The NASA/ESA Hubble Space Telescope has observed the variable star RS Puppis over a period of five weeks, showing the star growing brighter and dimmer as it pulsates. These pulsations have created a stunning example of a phenomenon known as a light echo, where light appears to reverberate through the murky environment around the star.
QD Vision, Inc. today announced the newest family of its award-winning Color IQ™ optical component compatible with LCD systems utilizing 3mm light guide plates. The new optic represents a 25% width reduction from QD Vision’s previous offerings, making it the thinnest and most cost-effective quantum dot, Full Gamut 100% NTSC color LCD solution available today.
This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than our sun and 200 times larger.
Some beauty is revealed only at a second glance. Such a case is the giant asteroid Vesta, which was the object of scrutiny by the Dawn spacecraft from 2011 to 2012. Scientists at the Max Planck Institute for Solar System Research in Katlenburg-Lindau have now re-analysed the images of this giant asteroid obtained by Dawn’s framing camera. The images reveal in unprecedented detail not only geological structures that are invisible to the naked eye, but also landscapes of incomparable beauty.
Astronomers affiliated with the Supernova Legacy Survey (SNLS) have discovered two of the brightest and most distant supernovae ever recorded, 10 billion light-years away and a hundred times more luminous than a normal supernova. Their findings appear in the Dec. 20 issue of the Astrophysical Journal.
A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms.
Photolithography uses light beams to design thin geometric patterns on the substrates of semiconductors used in microelectronic devices. This is achieved using a chemical reaction on a light-sensitive chemical, called photoresist.
‘Radio Galaxy Zoo’, launching today, is a new ‘citizen science’ project that lets anyone become a cosmic explorer.
Since 2010, about 50,000 volunteers have taken to their computers to help astronomers catalog star-blown bubbles captured in images from NASA's Spitzer Space Telescope. Their efforts resulted in several scientific papers, and a deeper understanding of our Milky Way galaxy and its frothy star-forming clouds.
