Pluto at Last! NASA Spacecraft Arrives for Dwarf Planet Close-Up Tuesday

The long wait is almost over.

On Tuesday morning (July 14) — nine and a half years after launching, and a quarter-century after its mission began to take shape — NASA's New Horizons spacecraft will perform
history's first flyby of Pluto. Closest approach will occur at 7:49 a.m. EDT (1149 GMT) Tuesday, when New Horizons zooms within just 7,800 miles (12,500 kilometers) of the dwarf planet's frigid surface.

Just think, if mankind ever gets really technologically advanced someone will probably just reset the universe just like that @$$hat Kirk did in Star Trek or those boneheads in X-Men Days of Future Past so none of this really matters (or does it? (beware of Whig history)).

NASA's Cassini spacecraft has found something odd on the surface of Saturn's moon Tehtys.

The northern hemisphere is has been in summer for the last two years and the sun has been shining on the surface there in an area usually dark. This has allowed the Cassini probe to get some more detailed photo's of the surface which is normally not visible.

The photos have revealed the moon has an icy surface with red line stretching across it. NASA is not sure what the red lines are and at this point think they may be chemical impurities in the surface ice trapped by gasses coming from under the ice. They said the red lines run across impact craters which show geologically they are much newer than the rest of the surface

There's a famous argument between Leonard Susskin and Stephen Hawking about what went on with black holes. It was settled somewhat with Hawking being wrong but he got a consolation prize of naming the radiation that does escape through the poles being called Hawking radiation. Hawking claimed that information eaten by black holes disappear forever which goes against the first law of physics. Leonard showed that everything that is swallowed is actually all smeared in the horizon which lead to the holographic theory that everything is two dimensionsal. Looks like the argument may be back on. Interesting news for sure.

Could the light from stars be hiding evidence of extraterrestrial life? A giant “Starshade” could soon reveal answers.

Alien hunting isn’t just tabloid fodder anymore. Over the last few years, astronomers have discovered thousands of planets outside the Solar System, suggesting that the galaxy is teeming with worlds – at least as many as one planet per star, on average.

Exploding star shines brighter than any supernova seen

© Provided by AFP Superluminous supernova ASASSN-15lh was first glimpsed by twin telescopes with 14-centimeter diameter lenses in Cerro Tololo, Chile
The brightest exploding star ever detected has bewildered scientists with its incredible power, shining 570 billion times brighter than the Sun and twice as potent as any known supernova, scientists said Thursday.

Known as ASASSN-15lh, it is about 3.8 billion light years away from Earth, making it among the closest ever found in a class known as superluminous supernova, said the report in the journal Science.

"ASASSN-15lh is the most powerful supernova discovered in human history," said study lead author Subo Dong, an astronomer and research professor at the Kavli Institute for Astronomy and Astrophysics at Peking University.

At the heart of the supernova is an object that measures just 10 miles (16 kilometers) across.

But it is 200 times more powerful than the average supernova, and 20 times brighter than all the stars in our Milky Way Galaxy combined, leaving astronomers puzzled about how it generates such energy.

"We have to ask, how is that even possible?" said co-principal investigator Krzysztof Stanek of Ohio State University, which leads a project using a host of small telescopes around the world to detect bright objects in the universe, known as the All Sky Automated Survey for Supernovae, or ASAS-SN, pronounced "assassin."

ASAS-SN has discovered around 250 supernovae since 2014, including the latest one which began to flare up in June 2015.

It was first glimpsed by twin telescopes with 14-centimeter diameter lenses in Cerro Tololo, Chile.

Astronomers spread the word about the sighting of ASASSN-15lh, soon more observations poured in from larger, ground-based telescopes around the world and NASA's Swift satellite.

The 10-meter South African Large Telescope (SALT) observed the elemental signatures that verified ASASSN-15lh's distance and potency.

"Upon seeing the spectral signatures from SALT and realizing that we had discovered the most powerful supernova yet, I was too excited to sleep the rest of the night," said Dong, who learned of the SALT results at 2 AM in Beijing on July 1, 2015.

As to what could be powering the supernova, scientists remain stumped but hopeful that the Hubble Space Telescope will tell them more in the coming months about the supernova and the galaxy it calls home.

"The honest answer is at this point that we do not know what could be the power source for ASASSN-15lh," said Dong.

One theory is that the object at the center of the blast could be a very rare type of star called a magnetar, which spins rapidly and possesses an ultra strong magnetic field.

But if further research shows that the object lies in the center of a large galaxy, then it may not be a magnetar after all, or even a supernova.

Instead, it could be a sign of "unusual nuclear activity around a supermassive black hole," said a statement by Ohio University.

"It would be something never before seen in the center of a galaxy," it said.
