NASA’s Lucy Spacecraft Will Zoom In on Ancient Trojan Asteroids –Goal to Unveil Origin of the Solar System (and Possibly Life on Earth)

 

 

“Understanding the causes of the differences between the Trojans will provide unique and critical knowledge of planetary origins, the source of volatiles and organics on the terrestrial planets, and the evolution of the planetary system as a whole,” said Dr. Catherine Olkin, Lucy mission’s deputy principal investigator.

“The Last Word” –Clashing Conclusions on the Oumuamua Interstellar Mystery from SETI’s Seth Shostak and Harvard’s Avi Loeb

 

You would have though it was 1938 again following Orson Welles’ radio broadcast of the War of the Worlds the way the way Twitter lit up last week when the chairman of Harvard’s astronomy department, Israel-born theoretical physicist Avi Loeb, suggested that an alien spaceship was possibly on its way to Earth to study humankind, and probably had Stephen Hawking spinning in his grave.

Alien Water Worlds –“Astronomers Ask Could Complex Life Evolve There?”

 

Think of beautiful blue planets with endless oceans orbiting many of the Milky Way’s one trillion stars. Could they support life? Perhaps even intelligent life? “There may be life there,” says Lisa Kaltenegger of the Max Planck Institute for Astronomy and the Harvard-Smithsonian Center for Astrophysics. “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. Maybe life’s inventiveness to get to a technology stage will surprise us.”

“Sentinel Species of the 6th Mass Extinction” –Marine Mammals May Not Survive the Anthropocene

 

 

“Marine mammals, such as manatees or bottlenose dolphins, are sentinel species—the canary in the coal mine,” says Nathan Clark,  associate professor in Pitt’s Department of Computational and Systems Biology, and the Pittsburgh Center for Evolutionary Biology and Medicine. “If you follow their health, it will tell you a lot about potential environmental issues that could eventually affect humans.”

The Oumuamua Spacecraft Hypothesis –Harvard’s Avi Loeb Responds to the World’s Media

“Only a fraction of the interstellar objects might be technological debris of alien civilizations. But we should examine anything that enters the Solar System from interstellar space in order to infer the true nature of `Oumuamua or other objects of its mysterious population.”
