'Cold Spot' Anomaly Billions of Light Years Across --"Was Caused By a Collision With Another Universe"   

  "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 -

"Journey's End" --NASA's Cassini Spacecraft Heading Towards Its "End-of-Mission" Death Plunge Through Saturn's Rings (WATCH Today's 'Galaxy' Stream)  

    On April 21, the spacecraft made its final close approach to Saturn's moon Titan and will now begin its last set of 22 orbits around Saturn until it takes its death plunge into Saturn's atmosphere right on September 15. After the close approach that gave us Cassini's last image of Earth, the craft sent images and data back to earth for scientists to study the hydrocarbon seas and lakes on Titan's north polar region. The gravity from Titan set Cassini up for its Gra...

New NASA Discovery --"Our Sun and Planets Surrounded by a Gigantic Round Magnetic Field That Fills the Solar System"  

    New data from NASA's Cassini mission, combined with measurements from the two Voyager spacecraft and NASA's Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by a giant, rounded system of magnetic field from the sun—calling into question the alternate view of the solar magnetic fields trailing behind the sun in the shape of a long comet tail.

China's Climate-Change Scientists Find Links to Solar Winds  

  The solar flux is considered the fundamental energy source of earth's climate system on long time scales. In recent decades, some studies have noted that the tiny variations in solar activity could be amplified by the nonlinear process in climate system. But the astronomy factors, such as solar activity, presented intriguing and cutting-edge questions to better understand climate change.

Earth-Impacting Asteroids --For the 1st Time, Scientists Rank Seven Most Threatening Effects

If an asteroid struck Earth, which of its effects--scorching heat, flying debris, towering tsunamis--would claim the most lives? A new study has the answer: violent winds and shock waves are the most dangerous effects produced by Earth-impacting asteroids.

Ocean Jellies Now Recognized as Earth's Earliest Animal Species  

    For the last decade, zoologists have been battling over the question, "What was the oldest branch of the animal family tree?" Was it the sponges, as they had long thought, or was it a distinctly different set of creatures, the delicate marine predators called comb jellies? The answer to this question could have a major impact on scientists' thinking about how the nervous system, digestive tract and other basic organs in modern animals evolved. Now, a team of evolutionary bio

"Seeding the Cosmos for Life" --Violent and Explosive Star Birth Captured in the Orion Molecular Cloud  

    Star birth can be a violent and explosive event, as dramatically illustrated in new ALMA images.Around 500 years ago, a pair of adolescent protostars had a perilously close encounter that blasted their stellar nursery apart. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have examined the widely scattered debris from this explosive event, gaining new insights into the sometimes-fierce relationship among sibling stars. Shortly after starting to form

Volcanic Eruptions in Hawaii and Samoa --Yield "Fingerprints" of Conditions that Existed Shortly After Earth Formed  

  Earth's mantle is made of solid rock that nonetheless circulates slowly over millions of years. Some geologists assume that this slow circulation would have wiped away any geochemical traces of Earth's early history long ago. But a new study led by University of Maryland geologists has found new evidence that could date back more than 4.5 billion years. The authors of the research paper, published April 7 in the journal Science, studied volcanic rocks that recently erupted from vol

Hubble Zooms in on Giant Jupiter to Study Changes in Its Atmosphere --"Great Red Spot is Shrinking"

The NASA/ESA Hubble Space Telescope used this special configuration to capture an image of what is by far the largest planet in the Solar System. This image adds to many others made in the past, and together they allow astronomers to study changes in the atmosphere of the gas giant. On 7 April Jupiter will come into opposition, the point
