#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.
This provides observational evidence that the disk has a big donut hole encircling the central black hole.
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,
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 lower-mass black hole is the remnant of a smaller galaxy that merged with Mrk 231.
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.
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:

#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 rover has measured also radiation levels with a view to assessing the feasibility of humans spending time on the planet.
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,
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,
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

#Signs of liquid water found on surface of Mars, scientists say Despite its reputation as a forebodingly dusty, desolate and lifeless place,
Mars seems to be a little bit wet even today. Scientists reported on Monday definitive signs of liquid water on the surface of present-day Mars,
a finding that will fuel speculation that life, if it ever arose there, could persist to now."
"said Alfred S Mcewen, a professor of planetary geology at the University of Arizona and the principal investigator of images from a high-resolution camera on Nasa's Mars Reconnaissance Orbiter.
"Although young Mars was inundated by rivers, lakes and maybe even an ocean a few billion years ago,
In 2011, Mcewen and colleagues discovered in photographs from the Mars Reconnaissance Orbiter dark streaks descending along slopes of craters, canyons and mountains.
The average temperature of Mars is about minus 70 degrees Fahrenheit, but summer days near the Equator can reach an almost balmy 70.

#Ancient Mars had long-lasting lakes, rivers: Nasa Mars harboured long-lasting lakes and water streams about 3. 8 to 3. 3 billion years ago,
boosting the odds that life may have existed once on the Red planet, scientists, including one of Indian-origin,
have found. Using data from the Curiosity rover, Nasa's Mars science laboratory/Curiosity team has determined that, long ago,
water helped deposit sediment into Gale crater, where the rover landed more than three years ago. The sediment deposited as layers that formed the foundation for Mount Sharp,
The findings build upon previous work that suggested there were ancient lakes on Mars, and add to the unfolding story of a wet Mars, both past and present.
Last month, Nasa scientists confirmed current water flows on Mars."It's clear that the Mars of billions of years ago more closely resembled Earth than it does today.
Our challenge is to figure out how this more clement Mars was even possible, and what happened to that wetter Mars,
"said Michael Meyer, lead scientist for Nasa's Mars Exploration Program at Nasa Headquarters in Washington.
Before Curiosity landed on Mars in 2012, scientists proposed that Gale crater had filled with layers of sediments.
Some hypotheses were"dry, "suggesting that sediment accumulated from windblown dust and sand. Others focused on the possibility that sediment layers were deposited in ancient lakes.
The latest results indicate that these wetter scenarios were correct for the lower portions of Mount Sharp.
Based on the new analysis, the filling of at least the bottom layers of the mountain occurred mostly by ancient rivers and lakes over a period of less than 500 million years."
