NASA Confirms Evidence That Liquid Water Flows on Today’s Mars
Posted by Amnon H. Eden in category: space
New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.
Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times.
“Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”

NASA confirms that liquid water flows on Mars
Posted by Sean Brazell in categories: chemistry, humor, space
Liquid water exists on the surface of Mars during the planet’s warmer seasons, according to new research published in Nature Geosciences . This revelation comes from new spectral data gathered by NASA’s Mars Reconnaissance Orbiter (MRO), a spacecraft that studies the planet from orbit. The orbiter analyzed the chemistry of weird dark streaks that have been known to appear and disappear seasonally on the Martian surface. The analysis confirms that these streaks are formed by briny — or salty — water flowing downhill on Mars.
NASA has advertised these findings as the solution to a major Mars mystery: does the Red Planet truly have liquid water on its surface? Researchers have known that water exists in ice form on Mars, but it’s never been confirmed if water can remain in a liquid state. The space agency is claiming that we now have that answer.
This isn’t the first study to suggest liquid water is present in some form on Mars. Scientists have theorized for years that Mars was once home to a large ocean more than 4 billion years ago. And recent findings from the Mars Curiosity rover suggest that liquid water exists just underneath the Martian surface. The discovery of water on Mars has almost become a joke among planetary scientists. Alfred McEwen, a planetary geologist at Planetary Image Research Laboratory who also worked on this research, wrote in Scientific American that the studies have become extremely commonplace: “Congratulations — you’ve discovered water on Mars for the 1,000th time!” he joked.

Time Travel Could Become Reality Sooner Than You Think

According to scientists photons can travel through time. They already have simulated directing quantum light particles to the past for the first time in the history. University of Queensland scientists learned that a simulation of two wormhole-travelling photons might interrelate; signifying hopping through time is conceivable at smallest scales. Their study might help to comprehend how time-travel could be conceivable in the quantum realm. PhD student Martin Ringbauer spoke to The Speaker: “For the first, ‘photon one’ would travel through a wormhole into the past and interact with its older version. In the second, ‘photon two’ travels through normal space-time but interacts with a photon that is stuck in a time-travelling loop through a wormhole, known as a closed timelike curve (CTC).”
Tim Ralph, UQ Physics Professor, said: “We used single photons to do this, but the time-travel was simulated by using a second photon to play the part of the past incarnation of the time travelling photon.”

Stephen Hawking speaks with virtually no muscular movement

Next January Stephen Hawking will be 74 years old. He has lived much longer than most individuals with his debilitating condition. In addition to being an unquestionably gifted cosmologist, he has invited controversy by supporting the pro-Palestinian, Israel-BDS boycott and warning about the dangers of alien invaders who tap into our interstellar greetings
Antisemitism, notwithstanding, this man is a mental giant. He is Leonardo. He is Einstein. Like them, his discoveries and theories will echo for generations beyond his life on earth. He is that genius.
Forty years ago, when Stephen Hawking still had mobility, he delivered a paper on a mystery regarding information-loss for entities that cross the event boundary of a black hole.
In the mid 1970s, Astronomers were just discovering black holes and tossing about various theories about the event horizon and its effect on the surrounding space-time. Many individuals still considered black holes to be theoretical. Hawking’s analysis of the information paradox seemed extremely esoteric. Yet, last month (Aug 2015) , at Sweeden’s KTH Royal Institute of Technology, Hawking presented a possible solution to the paradox that he sparked.

A colorful and dazzling view of Pluto
Posted by Philip Raymond in categories: astronomy, science, space
[From Engadget]…
While NASA has already shown us Pluto’s best images yet, the administration is anything but done blowing our minds. What you see above is an enhanced high-resolution color view of Pluto, created with a combination of blue, red and infrared images. NASA says this photo, taken by New Horizons spacecraft, highlights Pluto’s diverse landforms and shows us its complex geological and climatological story — as much as scientists have been able to figure out, anyway. Over the past few months, NASA’s shared many things related to Pluto, including a closer look at its desolate surface and icy mountain range.
