Led by Chang-Beom Eom, a UW-Madison professor of materials science and engineering and physics, the multi-institutional team published its results in the Nov….
An electrical spark in a drop of water creates a bubble of hot vapor. As the bubble rapidly expands and cools, pressure from the surrounding liquid pushes…
This ongoing recycling keeps galaxies from emptying their “fuel tanks” and therefore stretches out their star-forming epoch to over 10 billion years. However,…
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…
Their results suggest that such magnetic fields play a key role in channeling matter to form denser clouds, and thus in setting the stage for the birth of new…
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…
Why the temperatures in the solar wind are almost the same in certain directions, and why different energy densities are practically identical, was until now…
Charged particles flow through, moving energy around, creating electric currents, and producing the aurora. Many of these particles stream in from the solar…
Müller and his students wrote a paper on their work that is appearing this week in Physical Review Letters, a prestigious peer-reviewed journal of the American…
