NASA's Hubble Space Telescope has looked deep into the distant universe and detected the feeble glow of a star that exploded more than 9 billion years ago. The sighting is the first finding of an ambitious survey that will help astronomers place better constraints on the nature of dark energy, the mysterious repulsive force that is causing the universe to fly apart ever faster.
You may have heard by now about the 100 Year Starship project, a new research initiative to develop the technology required to send a manned mission to another star. The project is jointly sponsored by NASA and the Defense Advanced Research Projects Agency (DARPA). It will take that long just to make such a trip feasible, hence the name. So we’re a long ways off from naming any crew members or a starship captain, but the project itself does have a new leader, a former astronaut.
(PhysOrg.com) -- For the first time, astronomers have mapped dark matter on the largest scale ever observed. The results, presented by Dr Catherine Heymans of the University of Edinburgh, Scotland, and Associate Professor Ludovic Van Waerbeke of the University of British Columbia, Vancouver, Canada, are being presented today to the American Astronomical Society meeting in Austin, Texas. Their findings reveal a Universe comprised of an intricate cosmic web of dark matter and galaxies that spans more than one billion light years.

A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones.
A better understanding of the universe will be the outgrowth of the discovery of the Higgs boson, according to a team of researchers. The team predicts the discovery will lead to supersymmetry or SUSY -- an extension of the standard model of particle physics. SUSY predicts new matter states or super partners for each matter particle already accounted for in the standard model. SUSY theory provides an important new step to a better understanding of the universe we live in.
On Wednesday, Jan. 18, astronomers, physicists and scientists from related fields will convene in Tucson, Ariz. from across the world to discuss an endeavor that only a few years ago would have been regarded as nothing less than outrageous. The conference is organized by Dimitrios Psaltis, an associate professor of astrophysics at the University of Arizona
Astronomers have released the largest data set ever collected that documents the brightening and dimming of stars and other celestial objects -- two hundred million in total.
Scientists have developed a new method for optical manipulation of matter at the nanoscale. Using ‘plasmonic hotspots’ – regions with electric current that heat up very locally – gold nanostructures can be melted and made to produce the smallest nanojets ever observed. The tiny gold nanodroplets formed in the nanojets, are perfectly spherical, which makes them interesting for applications in medicine.
Astronomers have used visual data from nearly a million luminous galaxies for the most accurate calculation yet of how matter clumps together in the universe. By deriving cosmic rulers from an immense volume of sky, from a time when the universe was half its present age until now, the study establishes how much dark matter, dark energy, and even hard-to-detect neutrinos it contains.
NOTE: This is an excerpt from a 30-minute DVD. http://www.thinkingallowed.com/2nherbert.html The mysteries of sub-atomic physics offer us startling new perspectives on the human mind. Physicist Nick Herbert, Ph.D., author of Quantum Reality, points out that no matter how one interprets the equations of quantum physics the results lead to amazing and paradoxical concepts. Perhaps that time runs backwards as well as forward. Perhaps multiple independent universes are created each second.
