We Might Finally Know What Smacked Uranus Sideways

  We Might Finally Know What Smacked Uranus Sideways A planet twice the size of Earth gave our most unfortunately named planet its odd tilt.New research published today in the Astrophysical Journal suggests that Uranus got hit by a planet twice the size of Earth long ago. This collision could have radically changed the planet, resulting in its telltale tilt and making it relatively frigid compared to farther-out Neptune.

This plasma-spewing quasar is spurting out brighter radio emissions than anything else ever observed in the early universe . Three main components of the object are seen , with two of them showing further substructure.

Brightness is relative to the distance between the observer and the object , and this fact is what Although brighter than the brightest stars, these still aren’t the heavyweights of the universe . They are actually remnants of the early universe , when things were more chaotic, for lack of a better word.

This plasma-spewing quasar is spurting out brighter radio emissions than anything else ever observed in the early universe.

The brilliant celestial object could help scientists unlock the secrets of the universe's very first galaxies. Astronomers tracked the mysterious quasar using the National Science Foundation's Very Long Baseline Array. They detailed their findings in two papers published Monday in The Astrophysical Journal and The Astrophysical Journal Letters.

'If you don't want to see it, don’t watch it!' Miss Universe Australia Francesca Hung hits back at haters of the swimsuit section a as other pageants cancel the bikini show

  'If you don't want to see it, don’t watch it!' Miss Universe Australia Francesca Hung hits back at haters of the swimsuit section a as other pageants cancel the bikini show Eurasian model Francesca Hung, from Sydney, took out the prestigious Miss Universe Australia title for 2018 last week. And after claiming to have felt underestimated by her critics for years, the fierce 24-year-old has taken aim at the pageant's haters.Speaking to the Daily Telegraph on Thursday about the potential of axing the bikini segment of the competition, Francesca didn't hold back.'With a beauty pageant, if you don't agree with it or you don't want to see girls strutting around in bikinis, then you don't have to watch it,' she said.

No, this is not the brightest object in the universe ! It is not even a particularly bright star. It became the most distant object ever seen with binoculars ( see here) and even though it is too early to give an exact value for peak brightness , it appears that it has reached a bolometric magnitude in

As the black hole gobbles stuff up, it spews radio waves and light which can be seen from great distances. This newly-discovered quasar is incredibly far away — approximately 13 billion light That’s what makes it so hard to crown a king when we’re talking about “ the brightest object in the universe .”

"There is a dearth of known strong radio emitters from the universe's youth," study author Eduardo Bañados from the Carnegie Institute for Science said in a statement. This quasar, he added, was brighter than any other object spotted in the early universe "by a factor of 10."

This incredible brightness allowed astronomers to get a great look at the quasar, which is called PSO J352.4034-15.3373, or P352-15 for short. "This is the most-detailed image yet of such a bright galaxy at this great distance," study author Emmanuel Momjian from the National Radio Astronomy Observatory (NRAO) added in the statement.

Although astronomers are sure they've spotted a quasar, they don't know exactly which elements they've picked up in their image. Three components jump out of the shot (below) and scientists think these correspond to one of two options.

Einstein’s Theory Of General Relativity Tested In Extreme Gravity

  Einstein’s Theory Of General Relativity Tested In Extreme Gravity Scientists demonstrated the rules of gravity apply to even some of the most massive and densest objects in the known universe.Proposed more than a century ago, the famous theory from the physicist states all objects fall at the same rate, be it a feather or a cannonball.

The super- bright galaxy ULAS J1120+0641 is also the most distant quasar ever seen . It is by far the brightest object discovered from the early universe , giving off 60 trillion times as much light as our sun.

Astronomers have spotted the most distant supermassive black hole ever seen in our Universe — a “Already we can learn a lot about the early Universe with this one, but of course you want more Given the sheer amount of bright objects in the Universe , it makes the search long and tedious: the

A patch of light might on one side of the image might be the heart, with the other two smudges revealing a shooting plasma jet. Or, the bright patch in the middle is the quasar core and the other lights indicate jets bursting out from either side. Researchers think the first option—a one-sided jet—is more likely.

If they've spotted a one-sided jet, astronomers can track the object over several years to work out how fast it's expanding. If the middle object is the core, on the other hand, it could be very young, or shrouded in gas that's suffocating jet expansion.

The astronomers will have to make more observations before they'll be able to say exactly what's happening. This task, the NRAO's Chris Carilli said in the statement, is an exciting prospect.

“This quasar’s brightness and its great distance make it a unique tool to study the conditions and processes that prevailed in the first galaxies in the universe,” he said. “We look forward to unraveling more of its mysteries,” he added.

The National Radio Astronomy Observatory did not immediately respond to a request for comment.

Cosmos yields another secret .
Greatest question ever: Why is there anything, rather than nothing? They might, though, help us learn not only about dark matter, neutrinos and the nature of the universe, or even multiverse, but the answer to another compelling unknown; are we alone? Either answer is amazing. Maybe sooner than later, we’ll find out.
