Alien Ocean Worlds--“There May be Life There, but Could It be Technology-Based"

“These planets are unlike anything in our solar system. They have endless oceans,” says Lisa Kaltenegger of the Max Planck Institute for Astronomy and the Harvard-Smithsonian CfA. “There may be life there, but could it be technology-based like ours? Life on these worlds would be under water with no easy access to metals, to electricity, or fire for metallurgy. Nonetheless, these worlds will still be beautiful, blue planets circling an orange star — and maybe life’s inventiveness to get to a technology stage will surprise us.”

"Beyond Enigma" --Biology to Astrophysics: Scientists Apply Turing's Theory of Patterns in Nature

Alan Turing sought to explain how patterns in nature arise with his 1952 theory on morphogenesis. The stripes of a zebra, the arrangement of fingers, spirals of a galaxy and the radial whorls in the head of a sunflower, he proposed, are all determined through a unique interaction between molecules spreading out through space and chemically interacting with each other. Turing's famous theory can be applied to various fields, from biology to astrophysics.

The Alien Observatory --"The Mystery of Where Alien Life is Hiding Deepens"

"After searching the skies for Earthlike planets for centuries, cosmologists have, in the last two decades, broken open the cosmic piñata. Today they estimate as many as 500 billion billion sunlike stars, with 100 billion billion Earthlike planets. The more we learn about the universe, the more absurd it would seem if all but one of those bodies were bereft of life. To my mind, this is both the least likely answer to Fermi’s Paradox and the only one that fits all the evidence currently available to astrophysicists."

Ancient "Red Nuggets" Detected --Relics of the 1st Massive Galaxies in the Universe with Gigantic Supermassive Black Holes


Mrk1216

 

Red nuggets are relics of the first massive galaxies that formed within only one billion years after the Big Bang. While most red nuggets merged with other galaxies over billions of years, a small number remained solitary. These relatively pristine red nuggets allow astronomers to study how the galaxies — and the supermassive black hole at their centers — act over billions of years of isolation.

"Cosmic Sleuths" --Missing Baryons of the Universe Found Hidden Between an Ancient Quasar and Our Solar System

Ordinary, baryonic, matter exists in the vast spaces between galaxies as highly-ionized oxygen gas at temperatures of about 1 million degrees Celsius. To pin down the missing third, the researchers used the radiation emanating from a distant, ultra-bright black hole called a quasar. That lost matter exists as filaments of oxygen gas at temperatures of around 1 million degrees Celsius that lie in the space between galaxies, said CU Boulder’s Michael Shull, a co-author of the study.

China’s Land Grab Beyond the Blue Planet --"First the Moon, Then Mars" (Today's Top Space Headline)

“The universe is an ocean, the moon is the Diaoyu Islands, Mars is Huangyan Island, says Ye Peijian is a 73-year-old aerospace engineer and head of the Chinese lunar exploration program. "If we don't go there now even though we’re capable of doing so, then we will be blamed by our descendants. If others go there, then they will take over, and you won’t be able to go even if you want to. This is reason enough. It’s a move to wrest control of new lands from other nations, and to write the histories of those territories before others can.”

EcoAlert --27 New Viruses Discovered in Bees --"World Populations are Declining"

"Populations of bees around the world are declining, and viruses are known to contribute to these declines," said David Galbraith, research scientist at Bristol Myers Squibb and a recent Penn State graduate. "Despite the importance of bees as pollinators of flowering plants in agricultural and natural landscapes and the importance of viruses to bee health, our understanding of bee viruses is surprisingly limited."

Today's 'Planet Earth Report' --A Global Harbinger --"Climate Change Brought a Lobster Boom. Now It Could Cause a Bust"

"Warming waters in the Gulf of Maine have benefited lobsters and the lobstermen who trap them. But as temperatures rise further, will the industry reach a tipping point? The maximum water temperature that a lobster can tolerate is about 70 degrees Fahrenheit. Beyond that, “their system starts shutting down, one organ after another,” said Dr. Richard Wahle, director of the Wahle Lab and a leading expert on the America lobster. Consecutive days above this limit in Southern New England, he said, had lead to “mass mortality.”

"Alien Data" --Kepler "K2" Mission Yields Exciting New Planets Amid 50,000 Milky-Way Stars

"We found one of the most exciting planets that K2 has found in its entire mission, and we did it more rapidly than any effort has done before," says Ian Crossfield, an assistant professor of physics at MIT. "This is showing the path forward for how the TESS mission is going to do the same thing in spades, all over the entire sky, for the next several years."
