Titanic Death of a Massive Star --"Brightest Explosion in the Universe Morphs Into a Black Hole"  

In June 2016, an international team of 31 astronomers caught a massive star as it died in a titanic explosion deep in space. The blast of the dying star released in about 40 seconds as much energy as the Sun releases over its entire lifetime, all focused into a tight beam of gamma rays aimed by chance toward Earth. The gamma-ray blast on June 25, 2016, was detected by two NASA satellites that monitor the sky for such events, the Fermi Gamma-ray Space Telescope and the Swift Gamma-Ray

NASA Science Team to Track 2017 Total Solar Eclipse --"Will Chase Shadow of the Moon from Two Research Jets" (WATCH Today's 'Galaxy' Stream)  

"These could well turn out to be the best ever observations of high frequency phenomena in the corona," says Dan Seaton, co-investigator of the project and researcher at the University of Colorado in Boulder, Colorado. "Extending the observing time and going to very high altitude might allow us to see a few events or track waves that would be essentially invisible in just two minutes of observations from the ground." The total solar eclipse provides a rare opportunity for scie...

Modern Human Mental Disorders --"Shaped By Ancient Echo of Our Neanderthal DNA"  

    Researchers at the National Institute of Mental Health (NIMH) have produced the first direct evidence that parts of our brains implicated in mental disorders may be shaped by a "residual echo" from our ancient past. The more a person's genome carries genetic vestiges of Neanderthals, the more certain parts of his or her brain and skull resemble those of humans' evolutionary cousins that went extinct 40,000 years ago, says NIMH's Karen Berman, M.D. NIMH is part of the National

"Is the Monster Awakening?" Threat Level Raised for Europe's Supervolcano, Campi Flegrei Last Erupted in 1538  

    Campi Flegrei, "burning fields", is a supervolcano that consists of a vast and complex network of underground chambers that formed hundreds of thousands of years ago, stretching from the outskirts of Naples to underneath the Mediterranean Sea and last erupted in 1538. According o the BBC, about half a million people live in its seven-mile-long caldera, which was formed by vast eruptions 200,000, 39,000, 35,000 and 12,000 years ago.

    Dark matter is the aptly named unseen material that makes up the bulk of matter in our universe. But what dark matter is made of is a matter of debate. Scientists have never directly detected dark matter. But over decades, they have proposed a variety of theories about what type of material -- from new particles to primordial black holes -- could comprise dark matter and explain its many effects on normal matter.

Superluminous Supernova Discovered --"Most Distant Ever, Exploded at Cosmic High Noon"

The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after the big bang at a period known as "cosmic high noon," when the rate of star formation in the universe reached its peak.

Penrose proposes that the apparent noise is actually a real signal of gravitational waves generated by the decay of hypothetical dark-matter particles predicted by CCC.

New Research Reveals Early "Ghost Species" That Interbred With Humans  

In saliva, scientists have found hints that a "ghost" species of archaic humans may have contributed genetic material to ancestors of people living in Sub-Saharan Africa today. The research adds to a growing body of evidence suggesting that sexual rendezvous between different archaic human species may not have been unusual. Past studies have concluded that the forebears of modern humans in Asia and Europe interbred with other early hominin species, including Neanderthals and Denisovans.

NASA's Solar Observatory Films Rapidly-Growing Black Spot as It Rotates to Face Earth --"Dark Core is Larger Than Our Planet" (VIEW)   

  An active region on the sun — an area of intense and complex magnetic fields — has rotated into view on the sun and seems to be growing rather quickly in this video captured by NASA's Solar Dynamics Observatory between July 5-11, 2017. Such sunspots are a common occurrence on the sun, but are less frequent as we head toward solar minimum, which is the period of low solar activity during its regular approximately 11-year cycle. This sunspot is the first to appear after the sun...

NASA's Juno Spacecraft "Great Red Spot Diary" --Amazing New Images of the Oldest Storm in the Solar System  

  "For hundreds of years scientists have been observing, wondering and theorizing about Jupiter's Great Red Spot," said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. "Now we have the best pictures ever of this iconic storm. It will take us some time to analyze all the data from not only JunoCam, but Juno's eight science instruments, to shed some new light on the past, present and future of the Great Red Spot."

Inhabited 'Ocean Worlds' Beyond Our Solar System (VIDEO)  

    Recent research has found that the Earth's finely balanced oceans may be a consequence of the anthropic principle - more often used in a cosmological context - which accounts for how our observations of the Universe are influenced by the requirement for the formation of sentient life.  When it comes to exploring exoplanets, it may be wise to take a snorkel along.

Smallest Known Star in the Universe Discovered --"About the Size of Saturn"  

    The smallest star yet measured has been discovered by a team of astronomers led by the University of Cambridge. With a size just a sliver larger than that of Saturn, the gravitational pull at its stellar surface is about 300 times stronger than what humans feel on Earth. The star is likely as small as stars can possibly become, as it has just enough mass to enable the fusion of hydrogen nuclei into helium. If it were any smaller, the pressure at the centre of the star would
