Physicists' simulations show that collisions between hypothetical wormholes could produce short and powerful gravitational waves, different from those produced by black hole collisions. The research has not yet been peer-reviewed. Space-time is constantly rippled by gravitational waves that travel through…
The cool white dwarf WDJ1330+6435 has accreted sodium-rich rocky material from its planetary system into its atmosphere. The immense atmospheric density causes the sodium to absorb light over broad range of yellow, orange, and red wavelengths, giving the WDJ1330+6435 a ghostly green…
Home - Science - Around Antarctica, 1,712 zircon crystals drilled from the seafloor point to Himalayan-style mountains now buried under the ice, and two geologists say their erosion may have helped set the stage for the Cambrian explosion “Analyses of detrital zircons from…
India scientists have discovered geological locations in Tamil Nadu and Chile that are similar to Mars’s environment, which could allow scientists to learn about water processing on Mars and evaluate conditions that may have previously supported life. A team of…
During the cold season, the bright green and purple drapes that are called the aurora can be seen in the sky when looking up into the night. These drapes are a result of the Earth’s magnetic field reacting with the…
Home - Architecture News - Living Bacteria Create Stunning Sand Structures at ETH Zurich Bacteria have been binding sand into rock for millions of years. At ETH Zurich, an architect has taught them to do it on command, turning microscopic life into…
A world-record hard-X-ray pulse could open new ways to examine how matter responds to extreme light intensity. Electrons move so quickly inside atoms and molecules that studying their behavior requires flashes of light lasting just a fraction of a billionth…
When we look across the Universe, we might come to the conclusion that intelligent life is really a very rare thing indeed For as long as humanity has looked up at the stars, we have wondered whether someone, somewhere, might…
Scientists have discovered a powerful new way to decode the weather on distant worlds, revealing surprisingly organized patterns hidden within the turbulent atmosphere of a mysterious object 20 light-years from Earth. Researchers at Trinity College Dublin used observations from NASA's James…
RNZ / News / World Astronomers analyzing white dwarf stars have for the first time found a star that would appear green to human eyes, according to a new study. While for most stars, colour is temperature-dependent and limited to a few…
