For many research scientists, idle time has long been an unwelcome feature of the discovery process. Advances in cellular biology have yielded popular and powerful tools to detect cellular proteins and DNA — largely by exploiting the unique and intricate interactions between these microscopic molecules. Scientists use these tools to advance research and diagnose diseases. But these come at a cost in time — from hours to days — before they yield accurate answers.(more…)
Washington, D.C.—The Solar System has a new most-distant member, bringing its outer frontier into focus.
New work from Carnegie’s Scott Sheppard and Chadwick Trujillo of the Gemini Observatory reports the discovery of a distant dwarf planet, called 2012 VP113, which was found beyond the known edge of the Solar System. This is likely one of thousands of distant objects that are thought to form the so-called inner Oort cloud. What’s more, their work indicates the potential presence of an enormous planet, perhaps up to 10 times the size of Earth, not yet seen, but possibly influencing the orbit of 2012 VP113, as well as other inner Oort cloud objects.
