Planets and their stars form from the same reservoir of nebular material and their chemical compositions should therefore be correlated, but the observed compositions of planets do not match completely those of their central stars. In our Solar System, for example, all the rocky planets and planetesimals contain near-solar proportions of refractory elements (elements like ...
Far below the gaseous atmospheric shroud on Saturn’s largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Cornell astronomers have estimated Titan’s largest sea to be at least 1,000 feet deep near its center — enough room for a potential robotic submarine to explore. After sifting through data from one of the final Titan flybys of ...
Giant planets that developed early in a star system’s life could solve a mystery of why spiral structures are not observed in young protoplanetary discs, according to a new study by University of Warwick astronomers. The research, published in the Astrophysical Journal Letters and partially supported by the Royal Society, provides an explanation for the lack of ...
Life is deeply dependent on water, but where does it come from? Based on new research, researchers believe it may emerge in connection with the formation of planets. The emergence of life is a mystery. Nevertheless, researchers agree that water is a precondition for life. The first cell emerged in water and then evolved to ...
Astronomers have found compelling evidence that planets start to form while infant stars are still growing. The high-resolution image obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) shows a young proto-stellar disk with multiple gaps and rings of dust. This new result, published in Nature, shows the youngest and most detailed example of dust rings ...
Using data from the Dark Energy Survey (DES), researchers have found more than 300 trans-Neptunian objects (TNOs), minor planets located in the far reaches of the solar system, including more than 100 new discoveries. Published in The Astrophysical Journal Supplement Series, the study also describes a new approach for finding similar types of objects and ...
