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.
New NASA Technology --"One of Earth's Largest Volcanoes Helps Set the Stage for Human Exploration of Other Worlds" (VIDEO)
On the rust-colored north flank of one of Earth's largest volcanoes, a backpack-sized instrument monitors our atmosphere and, at the same time, helps set the stage for possible human exploration of other worlds. Designed and built at NASA's Goddard Space Flight Center, the instrument tracks levels of methane and carbon dioxide, two gases crucial for studying the chemistry of Earth's atmosphere. Portable and nearly self-contained, the unit could represent the start of a low-cost global network to provide atmospheric monitoring even in hard-to-reach locations.
NASA Alert: Cassini Takes 1st Dive Through Narrow Gap Between Saturn & its Rings Today --"A Region No Spacecraft has Ever Explored"
NASA's Cassini spacecraft is set to make its first dive through the narrow gap between Saturn and its rings on April 26, 2017. Because that gap is a region no spacecraft has ever explored, Cassini will use its dish-shaped high-gain antenna (13 feet or 4 meters across) as a protective shield while passing through the ring plane. No particles larger than smoke particles are expected, but the precautionary measure is being taken on the first dive.
NASA Out of Cassini Spacecraft Radio Contact Before Final Ring Dives and Death Plunge --"Will Gather Amazing New Data About This Huge World" (VIDEO)
Controllers and scientists must wait until Thursday to hear from the Cassini spacecraft that was due early on Wednesday to make the first of 22 dives in between Saturn's cloud tops and the inner edge of its spectacular rings designed to gather pictures and other science data of unprecedented resolution and science data that finally unlocks puzzles about the make-up and history of this huge world.
Researchers have discovered just that, identifying a new species of furry white bacteria covering a submerged volcano 130 meters (426 feet) below sea level in the Canary Islands that appeared to have started colonizing the volcano as soon as the temperature dropped.
"This means we can't entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard model. But if that isn't the answer, then there are more exotic explanations. Perhaps the most exciting of these is that the Cold Spot was caused by a collision between our universe and another bubble universe. If further, more detailed, analysis of CMB data proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse - and billions of other universes may exist like our own."
