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…
Galaxies are the birthplaces of stars, each with a dense, visible central core and a huge envelope, or halo, around it containing extremely low-density gases….
Instead of focusing on the large-scale, ecological impact of this problem, researchers from the Massachusetts Institute of Technology (MIT) in Cambridge and…
This ongoing recycling keeps some galaxies from emptying their “fuel tanks” and stretches their star-forming epoch to over 10 billion years. This conclusion is…
“This milestone is important as it marks the transition to the integration and testing phase for the Webb telescope's optical telescope element,” said Lee…
Many more such lakes exist throughout the shallow regions of Europa’s shell, the researchers predict in an online article for the journal Nature. Further…
Over three decades ago, Stephen Hawking placed — and eventually lost – a bet against the existence of a black hole in Cygnus X-1. Today, astronomers are…
For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its…

SDSC researchers submitted an entry for Gordon using 218 teraflops per second (Tflop/s) and 12,608 cores – about 75 percent of the system. Built by SDSC…
At this wavelength, most of the light seen is the weak heat glow from cosmic dust grains. The image therefore reveals the clouds of dust and molecular gas —…
University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make…
