The young star Eta Carinae –one of the most massive in the Milky Way – survived a titanic eruption 170 years ago. Although located relatively far away from Earth (about seven thousand light-years away, as compared with the average distance of naked-eye stars of about a thousand light-years), it can be seen easily by people in the southern hemisphere because it is extraordinarily bright—about five million times more luminous than our Sun.
The Universe has showered us with amazing, thought-provoking headlines this week, from why alien hunters have spent 60 years finding new solutions for the Drake Equation to the biggest “Oh No” moment in the Solar System to humanity’s unlikely gateway to space.
“We should plan ahead,” warned physicist Stephen Hawking who died March, 2018, and was buried next to Isaac Newton. “If a superior alien civilization sent us a text message saying, ‘We’ll arrive in a few decades,’ would we just reply, ‘OK, call us when you get here, we’ll leave the lights on’?

Black holes have been described as “the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time” by Nobel-Prize laureate Subrahmanyan Chandrasekhar.
“Oxygen flooded into the atmosphere as a pollutant, even a poison, until natural selection shaped living things to thrive on the stuff and, indeed, suffocate without it,” wrote evolutionary biologist, Richard Dawkins, in The Greatest Show on Earth: The Evidence for Evolution.
News from our Pale Blue Dot for the Thanksgiving Holiday weekend: from the “telescope that ate astronomy” to what “Impossible” meant to the legendary physicist, Richard Feynman to black-hole bubbles that could swallow to Universe to poaching triggers the evolution of tuskless elephants to tech companies ‘don’t get’ science-fiction.
“NASA’s ENIGMA (Evolution of Nanomachines In Geospheres and Microbial Ancestors) research team,” evolutionary biologist Paul Falkowski told The Daily Galaxy, “is focused on answering a single, compelling question in astrobiology: How did proteins evolve to become the predominant catalysts of life on Earth?
