Imagine someone spent months researching new cities to call home using low-resolution images of unidentified skylines. The pictures were taken from several miles away with a camera intended for portraits, and at sunset. From these fuzzy snapshots, that person claims to know the city's air quality, the appearance of its buildings, and how often it rains.
Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars.
Galileo mused that in order to understand the universe, we must first understand the language that it is written in. That language? Mathematics. But, if we look to the universe first we can see the ways it has inspired new approaches to even the purest mathematics. Using ideas from quantum field theory, elementary particle physics and string theory we are able to solve deep problems in incredible ways.
NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles.
Until 1931, physicist Albert Einstein believed that the universe was static. An urban legend attributes this change of perspective to when American astronomer Edwin Hubble showed Einstein his observations of redshift in the light emitted by far away nebulae—today known as galaxies. But the reality is more complex.
Squinting close to the beginning of time, Dominik Riechers, Cornell assistant professor of astronomy, has discovered an association of gas-rich galaxies near the infancy of cosmic time. It’s an early epoch – some 12.7 billion years ago – telling a tale that revolves around an exceptionally dusty galaxy called AzTEC-3.
Larry Smarr, a physicist whose work at the University of Illinois at Urbana-Champaign on calculating black hole collisions led him to champion a federal commitment to dramatically enhance U.S. computing power – which in turn led to the development of NCSA Mosaic, the precursor to web browsers – was named today as the first 2014 recipient of the Golden Goose Award.
More than 99.9% of the mass of any atom is concentrated into a quadrillionth of its volume, the part occupied by the nucleus. Unimaginably small, dense and energetic, atomic nuclei are governed by laws quite distinct from those that regulate atomic electrons, which constitute the outer part of atoms and which are immediately responsible for light, chemistry and thus life.
Three physicists at the Université de Sherbrooke led an international team to first direct measurement of the critical magnetic field in cuprates, the most promising materials for superconductivity. This breakthrough resolves an enigma that has baffled researchers for 20 years and clears the way for major advances. The study is published in the prestigious journal Nature Communications.
Faced with a federal funding shortfall, the University of Wisconsin-Madison has decided to shut down its Synchrotron Radiation Center near Stoughton on March 7.
Scientists on NASA's Interstellar Boundary Explorer (IBEX) mission, including a team leader from the University of New Hampshire, report that recent, independent measurements have validated one of the mission's signature findings—a mysterious "ribbon" of energy and particles at the edge of our solar system that appears to be a directional "roadmap in the sky" of the local interstellar magnetic field.
Forschungszentrum Jülich will lead a consortium of European partners to design a measuring system for the fusion experiment ITER. The facility is currently under construction in Cadarache in the south of France as part of a major international cooperation.
Founding director of Barclays Development Capital Ltd has created a new PhD position at the University of Liverpool that will allow a student to work at one of the world’s largest particle accelerator facilities.
NASA will host a news teleconference at 10 a.m. PST (1 p.m. EST) Wednesday, Feb. 19, to announce new observations from its high-energy X-ray mission, the Nuclear Spectroscopic Telescope Array (NuSTAR).
Armed with just the right atomic arrangements, superconductors allow electricity to flow without loss and radically enhance energy generation, delivery, and storage. Scientists tweak these superconductor recipes by swapping out elements or manipulating the valence electrons in an atom’s outermost orbital shell to strike the perfect conductive balance.
