(Phys.org)—A team of undergraduates from the Indian Institute of Science Education and Research (IISER) at the College of Engineering in Trivandrum, India, has designed and constructed a portable college-level radio telescope for amateur radio astronomers. The students have developed a radio telescope and also data analysis tools that are affordable for schools and colleges, combining low cost and ubiquitous accessibility of resources needed to build these instruments. The team described…

Using images from the NASA/ESA Hubble Space Telescope and ESO's Very Large Telescope, astronomers have discovered never-before-seen structures within a dusty disc surrounding a nearby star. The fast-moving wave-like features in the disc of the star AU Microscopii are unlike anything ever observed, or even predicted, before now. The origin and nature of these features present a new mystery for astronomers to explore. The results are published in the journal Nature on 8 October 2015.

There’s a region in the distant Universe where a handful of supermassive black holes have mysteriously aligned, and as a result, they’re spewing out incredibly powerful radio jets in the same direction. This is the first time astronomers have seen...

Researchers from the University of Liverpool are using strategic game theory to analyse the accumulation of space debris, and to assess removal efforts and mitigation measures to limit its growth.

(Phys.org)—Although in theory it may seem possible to divide time up into infinitely tiny intervals, the smallest physically meaningful interval of time is widely considered to be the Planck time, which is approximately 10-43 seconds. This ultimate limit means that it is not possible for two events to be separated by a time smaller than this.

(Phys.org)—Many quantum technologies rely on quantum states that violate local realism, which means that they either violate locality (such as when entangled particles influence each other from far away) or realism (the assumption that quantum states have well-defined properties, independent of measurement), or possibly both. Violation of local realism is one of the many counterintuitive, yet experimentally supported, characteristics of the quantum world.

Space exploration is pretty amazing right now. Just yesterday, we launched the ExoMars 2016 spacecraft , which will hunt for signs of life on Mars, and by now, the Voyager 1 spaccraft is likely way out in interstellar space . NASA recently...
