This Week’s Top Space & NASA Headlines –“From Saturn’s Mysteries to a Sign of Another Universe”





NASA’s Cassini Spacecraft Completes 1st Dive Through Gap Between Saturn and Rings –“Beams Back Images of a Colossal Swirling Storm” (WATCH Today’s ‘Galaxy’ Stream)




"No spacecraft has ever been this close to Saturn before," Earl Maize, Cassini project manager and a researcher at NASA's Jet Propulsion Laboratory in California, said. "We could only rely on predictions, based on our experience with Saturn's other rings, of what we thought this gap between the rings and Saturn would be like." The raw images, which began to stream back early this morning, indicating the probe had survived its journey, show intricate structures and a dark, swirling storm. which NASA called a "giant hurricane".


Bubble of Spacetime –“A ‘Time Machine’ That Moves Greater Than Speed of Light Allowing It to Travel Back and Forward in Time”



After some serious number crunching, a University of British Columbia researcher has come up with a mathematical model for a viable time machine –a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time. Ben Tippett, a mathematics and physics instructor, whose field of expertise is Einstein's theory of general relativity, studies black holes and science fiction when he's not teaching. Using math and physics, he has created a formula that describes a method for time travel.


Newly Discovered ‘Ice Planet’ –“Helps NASA Understand Distribution of Planets in Milky Way’s Disk vs Center”




Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists’ understanding of the types of planetary systems that exist beyond our own.


NASA’s New Unified Theory of Solar Eruptions –“From Small Bursts to Giant Clouds of Plasma Blown into Space” (WATCH Today’s ‘Galaxy’ Stream)



Large and small scale solar eruptions might all be triggered by a single process, according to new research that leads to better understanding of the Sun’s activity. Researchers at Durham University, UK, and NASA’s Goddard Space Flight Center, USA, used 3D computer simulations to show a theoretical link between large and small scale eruptions that were previously thought to be driven by different processes.
