Technology and society: The “maker” movement could change how science is taught and boost innovation. It may even herald a new industrial revolution
Astronomers have spotted seven galaxies that existed just a few hundred million years after the universe’s birth, including one that may be the oldest found to date. The potential record-holding galaxy, known as UDFj-39546284, likely existed when the universe was just 380 million years old, researchers said, and may be the farthest galaxy ever seen….
Voyager will soon become the first man-made object to leave the solar system, scientists from NASA say. Voyager 1, which was launched in 1977, is expected to exit the solar system much sooner than previously thought. Voyager 1 and 2 are currently in what is known as the “Heliosheath” – the outermost layer of heliosphere…
Bending a black hole can juice it up. In extra dimensions, a black hole behaves like a fluid and a solid at the same time, and flexing the solid form may generate an electric field. Although these effects exist only in the theoretical realm, the underlying equations could help us puzzle out some of the…
With the successful landing and deployment of the Mars Curiosity Rover, humanity has been treated to a sneak peek at the Red Planet for the first time. The possibility of establishing space colonies has been a scientists’ dream for decades, but working out a way to keep humans alive on the outside Earth’s protective shell…
The Hubble Space Telescope is taking advantage of a naturally occurring lens in space to extend its range even more. Scientists report this week that Hubble has found several bright quasars — galaxies that are home to supermassive black holes — which are strategically positioned so that that are warping the light from even more…
Thank goodness for granite. If not for the formation and subsequent erosion of large quantities of metal-rich granite on a supercontinent that formed billions of years ago, the evolution of multicellular life—including us—could have been stifled or delayed, according to a new study. For much of its history, life on Earth existed as only single-celled…
