Monster Infant Star Discovered in Milky Way --"Thirty Times the Size of Our Sun"

Astronomers have identified a young star, located almost 11,000 light years away, which could help us understand how the most massive stars in the Universe are formed. This young star, already more than 30 times the mass of our Sun, is still in the process of gathering material from its parent molecular cloud, and may be even more massive when it finally reaches adulthood.

NASA Scientists --"Vast Ocean of Saturn's Moon Enceladus Could Be the Site of a Second Genesis"

Chris McKay, an astrobiologist with NASA  says: "I've been interested in the search for life in the Solar System for decades and I'm still flabbergasted by what we're seeing on Enceladus. It's such a small world so far from Earth, putting out such a wealth of organics and water and indications of habitability - it's astounding, and the samples are right there, free for the taking."

Join StarTalk's Neil deGrasse Tyson to Explore Parallel Universes and the “Meta-Universe” (LISTEN)

 

  Star-talk

 

Join Neil deGrasse Tyson and theoretical physicist and cosmologist Paul Steinhardt as they explore concepts like cosmic inflation, quantum tunneling, and whether gravity is extra-dimensional. Neil and Paul discuss whether the perception of time would be consistent across the multiverse, and whether reality and gravity are granular. Find out about the difference between the Big Bang and the Big Bounce.

EcoAlert: Mass Extinction of Earth's Large Mammals Predicted --"Loss Would be a Tremendous Tragedy"

“The loss of these magnificent animals would be a tremendous tragedy,” said Blaire Van Valkenburgh, a UCLA professor of ecology and evolutionary biology, and article co-author. “They are all that is left of a once much more diverse megafauna that populated the planet only 12,000 years ago. And more importantly, we have only just begun to understand the important roles they play in maintaining healthy ecosystems.”

World's Astronomers --"Our 21st Century Technology Too Primitive to Detect an Advanced Alien Civilization"

 

TMT.0.0

 

Some of the world's leading astronomers -- including Great Britain's former astronomer royal, the Cambridge physicist Lord Martin Rees -- believe aliens, rather than using different radio waves or visible light to signal, may be using an entirely different communication medium such as neutrinos or gravitational waves (ripples in the fabric of space-time) or using communication mechanisms we cannot even begin to fathom.

"Cosmic Radio!" --Listen to the Frequencies of the Universe Captured by ESO's ALMA Observatory (Weekend Feature)

ALMA Sounds is a meeting point between radioastronomy captured by the Atacama Large Millimeter/submillimeter Array (ALMA) and musical creations made from observations taken from the most important radiotelescope in the world. It arose from the recurring curiosity of artists and astronomers to understand and transcend the Universe.

Phantoms of the Milky Way --"Galactic Quakes Reveal Invisible Starless Galaxies Orbiting Our Galaxy"

The outer edges of the Milky Way's appear to be orbited by innumerable invisible galaxies. Three bright pulsating stars on the outskirts of the Milky Way galaxy could be beacons from an invisible dwarf galaxy that astronomers predicted was there based on its effects of galactic quakes in our galaxy. These galactic quakes, ripples in gas at the outer disk of our galaxy, have puzzled astronomers since they were first revealed by radio observations a decade ago. Now, astronomers believe these stars mark the location of a dark matter-dominated dwarf galaxy far beyond the edge of the Milky Way disk, which terminates at 60,000 light-years.

"Mars' Mystery" --NASA Scientists Baffled About Mar's Evolution: "We're Missing Something Important"

"Aside from the shapes of the continents, geologists had paleontological evidence that fossil plants and animals in Africa and South America were closely related, as well as unique volcanic rocks suggestive of a common spatial origin. The problem was that the broad community of earth scientists could not come up with a physical mechanism to explain how the continents could plow their way through Earth's mantle and drift apart. It seemed impossible. The missing component was plate tectonics," he says. "In a possibly similar way, we are missing something important about Mars."

Nearby Venus-Like Exoplanet --"Oxygen, But Not Necessarily Life"

The distant planet GJ 1132b intrigued astronomers when it was discovered last year. Located just 39 light-years from Earth, it might have an atmosphere despite being baked to a temperature of around 450 degrees Fahrenheit. But would that atmosphere be thick and soupy or thin and wispy? New research suggests the latter is much more likely.

China's Scientists Propose the Human 'Quantum Brain' --"The Source of Our Dominance on the Planet: More Complex Than a Galaxy"

Chinese scientists have proposed a new theory that explains why humans are so much more intelligent than animals even though our brains are often much smaller than those of other species. Researchers at the Wuhan Institute of Neuroscience and Neuro-engineering have previously carried out studies backing the theory that the brain not only processes and passes on information not only through electrical and chemical signals, but also with photons of light.
