The universe is expanding at an accelerating rate, or is it?
more »
Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery that the universe is expanding at an accelerating pace. This led to the widespread acceptance of the idea that the universe is dominated by a mysterious substance named 'dark energy' that drives this accelerating expansion. Now, a team of scientists has cast doubt on this standard cosmological concept. The evidence for acceleration may be flimsier than previously thought, they say, with the data being consistent with a constant rate of expansion.

Tracking waves from sunspots gives new solar insight
more »
The sun is constantly changing. Material courses through not only the star itself, but throughout its expansive atmosphere. Understanding the dance of this charged gas is a key part of better understanding our sun. Now, for the first time, researchers have tracked a particular kind of solar wave as it swept upward from the sun's surface through its atmosphere, adding to our understanding of how solar material travels throughout the sun.
