Astronomers describe the star birth web of the cosmic Tarantula Nebula

This composite image of the star-forming region of Doradus 30 — also known as the Tarantula Nebula — reveals areas of cold gas that could collapse to form stars.

The newly released image of 30 Doradus, also known as the Tarantula Nebula, reveals thin, spiderweb-like strands of gas that reveal a dramatic battle between gravity and stellar energy that could give astronomers an idea of ​​how massive stars have shaped this star formation. regions and why they continue to be born in these molecular clouds. This high-resolution image of the Tarantula Nebula, located 170,000 light-years from Earth, consists of data collected by the Atacama Large Millimeter/submillimeter Array (ALMA). Located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, the Tarantula Nebula is one of the brightest star-forming regions in our galaxy’s backyard. It’s also one of the most active in term

Marine fertility: Researchers study how nutrients get to the bottom of the food web

Credit: Public Domain CC0 Almost all marine life—fish, turtles, sharks, whales, and more—depends on marine food webs for survival. However, the foundation of this enormous flow of energy lies on the shoulders of the microscopic but mighty phytoplankton. Without essential nutrients such as phosphorus, the growth of these tiny floating marine plants is limited, and the effects of such restrictions flow through the ecosystem, impacting the abundance and diversity of marine creatures. A team of Florida State University and New Hampshire University researchers have published a new study looking at how one important source of the nutrient, dissolved organic phosphorus, is distributed across the global ocean surface where it is consumed by phytoplankton. The work was published today in Natural Geoscience . All living organisms, including phytoplankton, need phosphorus to synthesize DNA, RNA and other important organic compounds. In addition
