Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
A team of astronomers led by scientists at the California Institute of Technology (Caltech) has discovered the three smallest confirmed planets ever detected…
Since 2000, the three Sloan Digital Sky Surveys (SDSS I, II, III) have surveyed well over a quarter of the night sky and produced the biggest color map of the…
This is the sharpest visible-light image ever made of the nucleus of an external galaxy.The event horizon, the closest region around the black hole where light…
Blue is typically an indicator of hot, young stars. In this case, however, the stellar oddities are aging, sun-like stars that have prematurely cast off their…
The team predicts the discovery will lead to supersymmetry or SUSY—an extension of the standard model of particle physics. SUSY predicts new matter states or…
For years, astronomers have been developing a picture of galaxy evolution in which mergers between spiral galaxies could explain why nearby large elliptical…
The scientists, led by Assistant Professor of Physics and Astronomy Eric Mamajek of Rochester and the Cerro Tololo Inter-American Observatory, used data from…
Fermi's Large Area Telescope (LAT) scans the entire sky every three hours, continually deepening its portrait of the sky in gamma rays, the most energetic form…
In a random sky survey made in near-infrared light, Hubble found five tiny galaxies clustered together 13.1 billion light-years away. They are among the…
Racing outward at about one-quarter the speed of light, these “bullets” of ionized gas are thought to arise from a region located just outside the black hole's…
CMOS image sensors have long since been the solution of choice for digital photography. They are much cheaper to produce than existing sensors, and they are…
Members of the media are invited to visit the mirror lab on Jan. 14 between 9-11 a.m. MST to see the liquid glass as it is spun cast in a rotating oven at a…
No one has yet made a superlens, also known as a perfect lens, though people are trying. Optical lenses are limited by the nature of light, the so-called…
The answer to one of the most exciting questions in particle physics seems almost close enough to touch: Scientists at the Geneva research center CERN have…
Graphene is a sheet of carbon atoms arranged in a chicken wire structure. In its pristine state, it exhibits no signs of the conventional magnetism usually…
