Our home Laniakea

Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space. Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means ‘immeasurable heaven’ in Hawaiian.

Everyone produces waste, and the Swedes are no different. It’s what they do with it that is unusual. Sweden recycles and sorts its waste so efficiently that less than 1 percent ends up in landfills. But perhaps even more interesting, and somewhat controversial, is that Sweden burns about as much household waste as it recycles, over 2 million tons, and converts this to energy. But even with this amount of domestic waste, the country’s 32 waste-to energy (WTE) incineration plants can handle even more. And when Sweden runs out of its own garbage, it offers a service to the rest of garbage-bloated Europe: importing excess waste from other countries.
