“Milky Way Triage” –The Hubble and Kepler Space Telescopes In ER

 

“I don’t know how anyone can see the Hubble ‘Deep Field’ image and not feel like something else is going about its business out there,” writes Tracy K. Smith, U.S. poet laureate, whose father was an engineer on the Hubble Space Telescope.

Stephen Hawking’s Pre-UN Report: “Wake Up, Science Deniers! –“Earth is Morphing into Venus”

 

“Venus is like Earth in so many ways,” explains Stephen Hawking. “A sort of kissing cousin. She’s almost the same size as Earth, a touch closer to the Sun. And, she has an atmosphere that could crush a submarine.”

“A Prebiotic Earth” –Missing Link Found on Saturn’s Moon Titan

 

 

Saturn’s largest moon, Titan, may yield clues to the development of complex chemistry on other moons and planets, including Earth, explained Musahid Ahmed, a scientist in Berkeley Lab’s Chemical Sciences Division. “People use Titan to think about a ‘pre-biotic’ Earth—when nitrogen was more prevalent in the early Earth’s atmosphere.”

“Disequilibrium” –The Unmistakable Signal of Alien Biological Life

 

 

In spite of their differences, each period in Earth’s history –The Archean (4 billion to 2.5 billion years ago), the Proterozoic (2.5 billion to 541 million years ago) and the Phanerozoic (541 million years ago to the present)  –share at least one characteristic: chemical imbalances in their atmosphere. That’s because biological activity produces substances that otherwise have no business coexisting.

Cassini’s Final Saturn Orbits Yield Astounding Discoveries –Organic ‘Ring Rain’ to an Unknown Electric-Current System

 

Knowing Cassini’s days were numbered, its mission team went for gold. The spacecraft flew where it was never designed to fly. For the first time, it probed Saturn’s magnetized environment, flew through icy, rocky ring particles and sniffed the atmosphere in the 1,200-mile-wide (2,000-kilometer-wide) gap between the rings and the cloud tops. Not only did the flight path push the spacecraft to its limits, the new findings illustrate how powerful and agile the instruments were.
