"Something Incredible Is Out There" --Scientists on Hunt for Signs of Extraterrestrial Intelligence Detect 15 New Cosmic Radio Bursts From Deep Space

As Carl Sagan was fond of saying: “Somewhere, something incredible is waiting to be known." Astronomers on the hunt for signs of extraterrestrial intelligence have detected 15 Fast Radio Bursts from a dwarf galaxy located three billion light-years away. These exotic pulses have confounded scientists since they were first discovered a decade ago by astronomers using the Parkes radio dish in Australia.

NASA: "Weirdest Habitable Worlds" --Hubble Hints at 1st Signs of Water on TRAPPIST-1 Dwarf Star-System Planets (WATCH Today's 'Galaxy' Stream)

On 22 February 2017 astronomers announced the discovery of seven Earth-sized planets orbiting the ultracool dwarf star TRAPPIST-1, 40 light-years away. This makes TRAPPIST-1 the planetary system with the largest number of Earth-sized planets discovered so far. An international team of astronomers used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1. The results suggest that the outer planets of the system might still harbour substantial amounts of water. This includes the three planets within the habitable zone of the star, lending further weight to the possibility that they may indeed be habitable.

ALMA Observatory Detects Huge Hidden Reservoirs of Fuel That Feed Starburst Galaxies

A team led by Edith Falgarone (Ecole Normale Supérieure and Observatoire de Paris, France) has used the Atacama Large Millimeter/submillimeter Array to detect signatures of the carbon hydride CH+ in distant starburst galaxies, known for a much higher rate of star formation compared to sedate Milky Way-like galaxies, making these structures ideal to study galaxy growth and the interplay between gas, dust, stars, and the black holes at the centers of galaxies.

"The Black Hole Paradox" --New Theory Says Soon After Big Bang, Black Holes Lit Up the Universe

 

Maxresdefault

 

Soon after the Big Bang, the universe went completely dark. The intense, seminal event that created the cosmos churned up so much hot, thick gas that light was completely trapped. Much later—perhaps as many as one billion years after the Big Bang—the universe expanded, became more transparent, and eventually filled up with galaxies, planets, stars, and other objects that give off visible light. That's the universe we know today.

Space Travel "Transforms Astronauts' Bodies at the Molecular Level"

The effects of spaceflight on the human body have been studied actively since the mid-20th century. It is widely known that space conditions influence metabolism, thermoregulation, heart biorhythms, muscle tonus, the respiration system and other physiological aspects of the human body function. However, the molecular mechanisms which drive the physiological changes caused by space flights remain unknown.

NASA's Official Calendar of the First-of-Its-Kind Event at Saturn --"Fiery Death Plunge Nears for Cassini Spacecraft"

"The Cassini mission has been packed full of scientific firsts, and our unique planetary revelations will continue to the very end of the mission as Cassini becomes Saturn's first planetary probe, sampling Saturn's atmosphere up until the last second," said Linda Spilker, Cassini project scientist from NASA's Jet Propulsion Laboratory in Pasadena, California. "We'll be sending data in near real time as we rush headlong into the atmosphere -- it's truly a first-of-its-kind event at Saturn."

"Beyond Biology" --MIT's Max Tegmark on Life 3.0: Being Human in the Age of Artificial Intelligence" (VIDEO)

Despite the most powerful technologies we have today, all life forms we know of remain fundamentally limited by their biological hardware. None can live for a million years, memorize all of Wikipedia, understand all known science or enjoy spaceflight without a spacecraft. None can transform our largely lifeless cosmos into a diverse biosphere that will flourish for billions or trillions of years, enabling our universe to finally fulfill its potential and wake up fully. All this requires life to undergo a final upgrade, to Life 3.0, which can design not only its software but also its hardware. In other words, Life 3.0 is the master of its own destiny, finally fully free from its evolutionary shackles.

Isolated in a giant thermal vacuum chamber, NASA’s $8.6 billion next-generation observatory is riding out the worst of Hurricane Harvey, sitting inside a massive, sealed cryogenic chamber at the Johnson Space Center, home of the nation’s astronaut corps and the control center for the International Space Station, JSC is the heart of NASA’s human spaceflight program, a sprawling NASA facility in southeast Houston surrounded by rising floodwaters that some estimates put at 20 trillion gallons.

Models showing what happens to matter just before it is sucked into a black hole may need to be revised after laboratory experiments using the world’s most powerful X-ray machine contradicted one of our best theories performed at Sandia National Laboratories' Z machine, the most energetic laboratory X-ray source on Earth, can that can duplicate the X-rays surrounding black holes that otherwise can be watched only from a great distance and then theorized about.
