To celebrate the New Year - and to mark the formal debut of its online Image Gallery - the Gemini Observatory has released three striking new images.
Gemini North GMOS image of the “Fireworks Galaxy” NGC 6946 which straddles the boundries between the constellations of Cepheus and Cygnus.
The first, taken by the Gemini North telescope atop Mauna Kea on the big island of Hawaii, was made public on New Years Eve, 2004, and shows the face-on spiral galaxy NGC 6946 ablaze with galactic fireworks. Each explosion of pink is a region of active star formation, where the fierce light of newborn stars is exciting the surrounding hydrogen gas into incandescence. In addition, the fiercest and most massive of these stars have been burning themselves out and ending their lives in an even more spectacular fashion - by detonating in a string of cataclysmic, rapid-fire supernova explosions. Astronomers have observed eight supernovas in this one galaxy in the past 100 years, as opposed to just four in our own galaxy in the past 1000 years, and they suspect that the supernovas have been going off at that rate for tens of millions of years.
Indeed, for reasons that are still not clear, NGC 6946 is among the most prolific galaxies known for star birth and star death alike.

NASA keeps watch over space explosions

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
