"Very Strange Stars" --A Big Clue to the Source of Life in the Cosmos?


 
 
“Without phosphorus there would be no thought,” observed Jacob Moleschott a 19th-century physiologist and philosopher. Phosphorus is one of the six main elements that make up the human body and an essential element for life as we know it for the creation of DNA, cell membranes, bones and teeth in humans, and even the microbiome of ocean-dwelling plankton–as a possible signature in the search for life in the cosmos.
Unlike hydrogen, oxygen, carbon, nitrogen and calcium, phosphorus is rare. And it is even more scarce elsewhere in the Solar System. The source of its arrival on early Earth remains a mystery. ....

Most distant cosmic jet providing clues about early universe


 E-Mail
Astronomers using the National Science Foundation s Karl G. Jansky Very Large Array (VLA) and Very Long Baseline Array (VLBA) have found and studied the most distant cosmic jet discovered so far a jet of material propelled to nearly the speed of light by the supermassive black hole in a quasar some 13 billion light-years from Earth. The quasar is seen as it was when the universe was only 780 million years old, and is providing scientists with valuable information about how galaxies evolved and supermassive black holes grew when the universe was that young.
The studies indicate that the quasar a galaxy harboring a black hole 300 million times more massive than the Sun has a jet of fast-moving particles only about 1,000 years old. While other quasars have been found at its distance and beyond, it is the first found at such a distance with the strong radio emission indicating an active jet. Only a small fraction of quasars have such jets. ....
