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…
New Chandra images of Sagittarius A* (Sgr A*), which is located about 26,000 light-years from Earth, indicate that less than 1 percent of the gas initially…
The culprits are 65 of the hottest, brightest known stars, classified as O-type stars, located 15 light-years away from the knot, towards the right edge of the…
An international team of researchers presents fresh evidence that confirms the existence of the superheavy chemical element 115. The experiment was conducted…
Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot…
Operating a hard disk drive is as complex as keeping a superfast car on the road. Read/write heads within the hard disk must process a huge amount of data at…
The results, which could be of importance for a variety of applications, have been published in the current issue of Science Magazine. Titanium dioxide is an…

“This is the first time an experiment like this has simulated the evolution of structure in the early universe,” said Cheng Chin, professor in physics. Chin…
Disrupting the symmetrical structure of a solid-state topological crystalline insulator creates mass in previously mass-less electrons and imparts an…
“The goal of the LLCD experiment is to validate and build confidence in this technology so that future missions will consider using it,” said Don Cornwell,…
Using SDO, scientists see a performance of explosions and fountains on the solar surface. Shots of solar material leap into the air. Dark blemishes called…
Such events were predicted as early as 1970, but the first evidence for one now has come from the National Science Foundation's Very Long Baseline Array…
The best explanation for the findings, the authors said, is that Titan's ice shell is rigid and that relatively small topographic features on the surface are…
A modified law of gravity correctly predicted, in advance of the observations, the velocity dispersion — the average speed of stars within a galaxy relative…
A combination of metal and carbon layers enables to combine the two main characteristics “high expansion sensitivity” and “temperature-independence of the…
