young stars are surrounded by chaos: Clouds of gas, dust and ice swirl about in a so-called protoplanetary disk. And when gravity pulls this material together so that it binds, planets are born.카지노사이트 Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers developed a new technique to measure and date infant exoplanets forming in…

Since the 1990s, scientists have cataloged thousands of planets outside our solar system, called exoplanets. Some of these are massive and gaseous, while others are tiny and rocky like our home world. But a recent analysis suggests that some of these exoplanets might be more dense and have more water than previously thought, which has…
