"It's a cosmic miracle," said Volker Bromm of The University of Texas at Austin, referring to the precise set of conditions present half a billion years after the Big Bang that allowed these behemoths to emerge. "It's the only time in the history of the universe when conditions are just right" for them to form.

NASA Astronomers: "Pluto is a Planet, So is Jupiter's 'Ocean' Moon Europa"

 

Europa

 

Johns Hopkins University scientist Kirby Runyon wants to make one thing clear: Regardless of what one prestigious scientific organization says to the contrary, Pluto is a planet. So, he says, is Europa, commonly known as a moon of Jupiter, and so is the Earth's moon, and so are more than 100 other celestial bodies in our solar system that are denied this status under the prevailing definition of "planet."

China Takes Giant Step Toward Launching Its Space Station --"Will It Replace the ISS When Its Retired in 2024?"

 

Iss

 


In 2024, China's space station will become operational at the same time when the International Space Station (ISS)  shown above will retire, according to its current plans on development. The ISS is the most well-known artificial science laboratory on a worldwide scale, but China is currently working on taking its place with a space-based science lab. It's currently unknown if China is going to be the only country in the world to detain such a facility by that time.

ESO --"Dark Matter Halos of Early Galaxies Much Larger and Diffuse" --Dominated By Normal Matter (VIDEO)

New observations indicate that massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion years ago, were dominated by baryonic or 'normal' matter. This is in stark contrast to present-day galaxies, where the effects of mysterious dark matter seem to be much greater. This surprising result was obtained using ESO's Very Large Telescope and suggests that dark matter was less influential in the early universe than it is today.

"Andromeda Once Flew Past Our Milky Way Galaxy At Close Range" --New Discovery Upends Einstein's Theory of Gravity

Einstein's theory of gravity may have to be rewritten, after researchers at the University of St Andrews found a gigantic ring of galaxies darting away from us much faster than predicted. This 10 million light year-wide ring made up of small galaxies is expanding rapidly like a mini Big Bang. The team believe our neighboring galaxy, Andromeda, once flew past our own galaxy at close range, creating a sling-shot of several small galaxies.

Stellar Nursery Roars to Life --"An Intense, Dramatic Growth Spurt"

A massive protostar, deeply nestled in its dust-filled stellar nursery, recently roared to life, shining nearly 100 times brighter than before. This outburst, apparently triggered by an avalanche of star-forming gas crashing onto the surface of the star, supports the theory that young stars can undergo intense growth spurts that reshape their surroundings.

In the center of a distant galaxy, almost 300 million light years from Earth, scientists have discovered a supermassive black hole that is "choking" on a sudden influx of stellar debris.

NASA Probes the Unsolved Mysteries of Titan's Hydrocarbon Lakes (VIDEO)

NASA's Cassini spacecraft has found that the composition of Titan's lakes and seas varies from place to place, with some reservoirs being richer in ethane than methane. "Our experiments showed that when methane-rich liquids mix with ethane-rich ones -- for example from a heavy rain, or when runoff from a methane river mixes into an ethane-rich lake -- the nitrogen is less able to stay in solution," said Michael Malaska of JPL, who led the study. The result is bubbles. Lots of bubbles.

"Alpha Centauri Up Close!" --NASA Looks at Using the Sun as a Giant Gravity Lens to Study Alien Planets

 

Extreme-Ultraviolet-Sun

 

NASA says it could study distant exoplanets by using the sun as a giant gravity lens revealing (if it was Earth) islands, rivers, parks, Great Walls, freeways, cities, and so on. Imagine an alien spacecraft sitting at the gravitational focus of a distant star is revealing these details to a spellbound population.
