Curiously large dust grains may contribute to development of bodies in space. The Orion Nebula, courtesy of NASAInterstellar space can be a dusty place, filled with tiny flecks no bigger than a bacterial cell.But now astronomers have detected particles as big as pebbles, possibly a previously unknown type of dust that may kick-start the production of planets. The presence of these big particles may also suggest that star formation is more efficient than previously thought.Astronomers […]
Courtesy imgur user ScienceLlamaAt a glance, it’s easy to tell that something’s not right with the galaxies and clusters in these images from deep space, but it might sound silly when it’s put into words: they’re little! The photographic technique of miniature faking takes advantage of the way light is focused by a lens to trick your brain into perceiving something that’s thousands of light-years across as being small enough to fit into the palm of your […]
In the 1990's, the US Bureau of Land Management unintentionally became the worlds largest supplier of helium. Last year, the world faced a potential helium cliff, when the US government had to decide whether to keep selling helium or exit the market as they'd originally planned. Thankfully, the crisis was averted; this last July the US started auctioning off large chunks of its helium to other suppliers, in an effort to keep the helium market healthy. Today on the Phyiscs Central […]
Researchers have found out how orderly patterns of cracks form atop electronics.Originally published: Aug 29 2014 - 3:00pm, Inside Science News ServiceBy: Gabriel Popkin, Contributor(Inside Science) -- Repeating crescents, snail shell-like spirals and a jumble of shapes resembling a Keith Haring painting: These patterns and more can start to adorn old paintings, pottery glazes and even electronics under the right conditions. Now, a team of scientists from France and Chile has revealed the […]
If you spend much time browsing home-science channels on youtube, you’ve probably seen videos of what happens when you drop a magnet through a metal tube. If not, enjoy this mind-bending display of Eddy Current Braking. While it might be difficult to get your hands on such a large magnet and pipe, the phenomenon will occur with a tube of any size, as long as it’s made of a sufficiently conductive material and your magnet is powerful enough. While magnets will ordinarily only […]
