New images from the Smithsonian's Submillimeter Array (SMA) telescope provide the most detailed view yet of stellar nurseries within the Snake nebula. These images offer new insights into how cosmic seeds can grow into massive stars.
JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet.
This is a Hubble Space Telescope composite image of a supernova explosion designated SN 2014J in the galaxy M82. At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades.
In order to study what happened in the seconds immediately following the Big Bang, John Carlstrom went to Antarctica. It just so happens that one of the most inhospitable places on Earth provides some of the best conditions for pointing a telescope to the stars and glimpsing the remnants of "fossil light" emitted when the universe was born almost 14 billion years ago.
Galaxies grow by attracting and ingesting smaller galaxies, or by merging with other galaxies of comparable size. Now, a team of astronomers, including Glenn van de Ven from the Max Planck Institute of Astronomy, have identified the smallest example of a remnant of such a galactic merger: the dwarf spheroidal galaxy Andromeda II (AndII), a satellite of the well-known Andromeda galaxy.
Rodney J. Bartlett, University of Florida graduate research professor in chemistry and physics, has received the Humboldt Research Award recognizing lifetime achievements in research.
How do you build a universal quantum computer? Turns out, this question was addressed by theoretical physicists about 15 years ago. The answer was laid out in a research paper and has become known as the DiVincenzo criteria. The prescription is pretty clear at a glance; yet in practice the physical implementation of a full-scale universal quantum computer remains an extraordinary challenge.
Professor Mikhail Shifman, recent Pomeranchuk prize winner, says that particle physicists are experiencing a crucial time. And he ought to know. Shifman has written several books on the history of elementary particle physics. "We are at a crossroads, we will go to the left or to the right or nowhere" Shifman says, referring to the fact that supersymmetry, the theory that states that there are superpartners for every known particle, has not yet been discovered at the Large Hadron Collider.
As the next step in advancing NASA’s asteroid initiative, the agency will host an Opportunities Forum March 26 at NASA Headquarters in Washington.
Scientists on the CDF and DZero experiments at the U.S. Department of Energy's Fermi National Accelerator Laboratory have announced that they have found the final predicted way of creating a top quark, completing a picture of this particle nearly 20 years in the making.
The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers from the Niels Bohr Institute, among others, have detected a stream of stars in one of the Andromeda Galaxy's outer satellite galaxies, a dwarf galaxy called Andromeda II.
RIKEN, the University of Tokyo, and NIMS succeeded for the first time in generating and visualizing electron spin vortex state "skyrmion molecules" with topological charge 2 within a thin film of "La1+2xSr2-2xMn2O7," a layered manganese oxide which is a ferromagnetic material with uniaxial anisotropy.
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.
A physicist who studies the origin and makeup of the universe is the next speaker for Indiana State University's 203-14 University Speakers Series.
Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they're bigger than the entire planet and they can happen multiple times a day.
