#Hubble Reveals That Markarian 231 Is powered by a Double Black hole Using NASA Hubble space telescope, a team of astronomers discovered that Markarian 231 is powered by two central black holes furiously whirling about each other.
Markarian 231 is the nearest galaxy to Earth that hosts a quasar, located 581 million light-years away.
The finding suggests that quasarshe brilliant cores of active galaxies may commonly host two central supermassive black holes,
which fall into orbit about one another as a result of the merger between two galaxies. Like a pair of whirling skaters, the black-hole duo generates tremendous amounts of energy that makes the core of the host galaxy outshine the glow of its population of billions of stars
which scientists then identify as quasars. Scientists looked at Hubble archival observations of ultraviolet radiation emitted from the center of Markarian 231 (Mrk 231) to discover what they describe as xtreme and surprising properties.
If only one black hole were present in the center of the quasar, the whole accretion disk made of surrounding hot gas would glow in ultraviolet rays.
Instead, the ultraviolet glow of the dusty disk abruptly drops off toward the center. This provides observational evidence that the disk has a big donut hole encircling the central black hole.
The best explanation for the donut hole in the disk based on dynamical models, is that the center of the disk is carved out by the action of two black holes orbiting each other.
The second, smaller black hole orbits in the inner edge of the accretion disk, and has its own mini-disk with an ultraviolet glow. e are excited extremely about this finding
because it not only shows the existence of a close binary black hole in Mrk 231, but also paves a new way to systematically search binary black holes via the nature of their ultraviolet light emission,
said Youjun Lu of the National Astronomical observatories of China, Chinese Academy of Sciences. he structure of our universe,
such as those giant galaxies and clusters of galaxies, grows by merging smaller systems into larger ones,
and binary black holes are natural consequences of these mergers of galaxies, added co-investigator Xinyu Dai of the University of Oklahoma.
The central black hole is estimated to be 150 million times the mass of our sun, and the companion weighs in at 4 million solar masses.
The dynamic duo completes an orbit around each other every 1. 2 years. The lower-mass black hole is the remnant of a smaller galaxy that merged with Mrk 231.
Evidence of a recent merger comes from the host galaxy asymmetry and the long tidal tails of young blue stars.
The result of the merger has been to make Mrk 231 an energetic starburst galaxy with a star formation rate 100 times greater than that of our Milky way galaxy.
The infalling gas fuels the black holesngine triggering outflows and gas turbulence that incites a firestorm of star birth.
The binary black holes are predicted to spiral together and collide within a few hundred thousand years. Mrk 231 is located 600 million light-years away.
The results were published in the August 14, 2015 edition of The Astrophysical Journal. PDF Copy of the Study:

#Physicists Observe and Control Quantum Motion For the first time, a team of physicists has discovered a way to observe
and control quantum motion of an object that is large enough to see. Consider the pendulum of a grandfather clock.
If you forget to wind it, you will eventually find the pendulum at rest, unmoving. However, this simple observation is only valid at the level of classical physicshe laws
and principles that appear to explain the physics of relatively large objects at human scale.
However, quantum mechanics, the underlying physical rules that govern the fundamental behavior of matter and light at the atomic scale,
state that nothing can quite be completely at rest. For the first time, a team of Caltech researchers and collaborators has found a way to observend controlhis quantum motion of an object that is large enough to see.

#Nasa Finds Liquid Water On Mars In a Mars-related press conference this morning NASA has announced that nder certain circumstancesliquid water has been found on Mars. ars is not the dry arid planet that we thought of in the past,
Previously it was known that H20 existed on Mars in the form of ice but scientists had thought the atmosphere of Mars was too thin for liquid water to be possible.
The scientists used a spectroscopy technique to analyze the chemical composition of dark streaks (which NASA refers to as Recurring Slope Lineae
or RSL) they had observed previously on the Martian surface. These streaks had been noticed to vary following temperature changes on the surface leading to a hypothesis that the substance was water.
Late last week the agency trailed a ajor science findingfrom its ongoing exploration of the red planet showing continued savvy at NASA social media mission to sustain public interest in space exploration.
NASA landed its Curiosity rover on Mars back in August 2012 and the bot has been exploring the surface
ever since with NASA extending what was slated originally as a two-year mission back at the end of 2012. Its Opportunity rover,
which landed on the Martian surface back in 2004, is also still active currently surveying a portion of the surface called Marathon valley.

The presence of perchlorate in the Martian soil improves the stability of liquid water on the surface of Mars,
NASA scientists said today enabling the liquid water to exist for longer before either freezing as the temperature on the planet drops,
or boiling away in its thin atmosphere. This means that Marswater is riny rather than ure The viability for life to exist in this water is ot clearat this stage,
NASA added although the presence of liquid water itself gives a huge boost to that search. y feeling
when you look at Earth, water is an essential ingredient for life This is tremendously exciting. We haven been able to answer the question oes life exist beyond Earth,
but finding water is critical to that. We now have, I think, great opportunities to be in the right locations on Mars to thoroughly investigate that,
said Jim Green, director of planetary science at NASA. Investigating the RSL sites themselves to probe for life is challenging, according to NASA,
because the streaks have so far only been observed on steep slopes. So it said directly probing
whether they contain life is likely to be he domain of future robotics spacecraft specifically designed to go therecraft
which are sterilized also rigorously to avoid contamination by Earth-based microbes. Exactly where the liquid that appears in the RSL comes from is unclear at this stage.
The presence of liquid water on Mars could also help any future human mission to the planet
NASA added. t took multiple spacecraft over several years to solve this mystery, and now we know there is liquid water on the surface of this cold, desert planet,
added Michael Meyer, lead scientist for NASA Mars Exploration Program at the agency headquarters in Washington. t seems that the more we study Mars,
the more we learn how life could be supported and where there are resources to support life in the future. r

In a paper published in the journal Nature Geoscience, Mcewen and other scientists identified waterlogged molecules salts of a type known as perchlorates in readings from orbit."

In 2011, Mcewen and colleagues discovered in photographs from the Mars Reconnaissance Orbiter dark streaks descending along slopes of craters, canyons and mountains.

and its presence raises the question of whether Mars, which appears so dry and barren, could possess niches of habitability for microbial Martians.
Christopher P Mckay, an astrobiologist at Nasa's Ames Research center in Mountain view, California, does not think the RSLS are a very promising place to Look for the water to be liquid
it must be so salty that nothing could live there, he said.""The short answer for habitability is it means nothing,
David E Stillman, a scientist at the Southwest Research Institute's space studies department in Boulder, Colorado, said water for the streaks might be different in different regions.
"Even though RSLS appear to be some of the most intriguing features on Mars, no one is likely to get a close up look any time soon.
RSLS are treated as special regions that Nasa's current robotic explorers are barred from because the rovers were sterilized not thoroughly,
and Nasa worries that they might be carrying microbial hitchhikers from Earth that could contaminate Mars. Of the spacecraft Nasa has sent to Mars,
only the two Viking landers in 1976 were baked to temperatures hot enough to kill Earth microbes.
Nasa's next Mars rover, scheduled to launch in 2020 will be no cleaner. Sterilizing spacecraft, which requires electronics
and systems that can withstand the heat of baking, adds to the cost and complicates the design.
the space agency is ruling out places that might be habitable, including those with RSLS. That prohibition may continue
even though two candidate RSLS have been identified on the mountain in Gale crater that Nasa's Curiosity rover is now exploring, not very far from its current planned path.
