A new interactive map of satellites and "space junk" has launched, showing hundreds of thousands of objects orbiting Earth. Along with many active satellites the map shows inactive tech, bodies of rockets used to launch the devices, and debris. ...
Space junk includes transfer stages from old Russian rockets, defunct satellites and scientific mission clutter. Several 100-pound-plus fragments have crashed to Earth. There are no regulations controlling the generation of junk, only recommendations to minimize it.Kleeman, Elise...
In recent decades, space missions have increasingly relied on the ability to change the course of a satellite’s path through space without using fuel. One way of doing this is to find ‘heteroclinic connections’ – the paths that allow spacecraft to transfer from one orbit to another without...
Long ago, before a host of satellites and space junk orbited the earth, before Uber and Google Maps, people actually used paper maps and a compass to navigate. If you plan to spend any time out in the great outdoors, then knowing how to use a map and compass is a key skill. Regardl...
ii. The process of transcribing weather information onto maps, diagrams, and so on; it usually refers specifically to decoding synoptic reports and entering those data in a conventional station-model form onto synoptic charts. Also known asmap spotting. Seesynoptic chart. ...
Scientists call on UN to help solve Earth's space junk problem 'Heavy' dark matter would rip our understanding of the universe apart, new research suggests 3D structure of iconic Ring Nebula gives 'a brand new view of an old astronomical friend' How President Trump could change NASA 'Silo'...
Certainly, Hubble's longevity in space is an advantage here, as is its powerful resolution from its vantage point high above Earth's turbulent atmosphere. The proper motion of the Draco dwarf's stars over the course of 18 years at a distance of a quarter of a million light years is tiny...

Athens is a sprawling city established among seven historic hills and surrounded by remarkable mountains. Inhabited for more than 3,000 years, Athens is widely known as the cradle of Western civilization and the birthplace of democracy. Consisting of a l
one of the most ambitious space projects yet. It aims to launch a space observatory to create the most detailed ever map of the sky. In the process, it will survey hundreds of millions of galaxies — some of which are so far away that their light takes 10 billion years to reach Earth...
