Hello all,

Dust disc around star mysteriously disappears, calling into question how our solar system was formed

Posted on July 28, 2012

I would normally post a pic but im STILL having probs with that issue.

July 28, 2012 – SPACE - A disc of planet-forming dust around a distant star has disappeared unexpectedly, leaving astronomers scratching their heads and questioning current theories of how planets are formed. “It’s like the classic magician’s trick: Now you see it, now you don’t,” said astronomer Carl Melis of UC San Diego, who led the team that discovered the phenomenon. “Only in this case, we’re talking about enough dust to fill an inner solar system and it is really gone.” The team has proposed several possible explanations for the disappearance, but “none are really compelling,” Melis said.

These will make you starry-eyed! Photographers look to the night sky for dazzling astronomical displays

The rich colours, dusting of stars, smattering of bright lights and ethereal patterns look almost like they are a work of fiction.

But the beautiful images are just photographs of the night sky.

Huge eruptions shooting from the Sun’s surface, the dazzling green and red lights of the aurora borealis, and spectacular clouds of colourful dust in which new stars are forming thousands of light years away; these are just some of the awe-inspiring sights captured by photographers.

The dazzling displays were photographed for the 2012 Astronomy Photographer of the Year competition - and the entries show just how spectacular the sky is.

Hubble's hidden treasures: Stunning pictures from the space telescope which only saw the light of day thanks to amateurs

These incredible images of deep space taken by the Hubble Space Telescope would have never been seen if it wasn't for the hard work of dedicated amateurs.

With over a million observations since the Hubble's launch 22 years ago, many of its most striking images have lain hidden in the Space Telescopes data vaults.

That was until the European Space Agency opened them up to the public, and invited skywatchers to delve into the archives and search for the hidden treasures the scientists missed - and offered prizes for the most striking images.

The Milky Way as you've never seen it before: New nine GIGAPIXEL image reveals our galaxy in unprecedented detail

Unique view is a monumental 108,200 by 81,500 pixel colour image containing nearly nine billion pixels

iIf printed with the resolution of a typical book, it would be 9 metres long and 7 metres tall

A new striking nine-gigapixel image has captured a catalogue of more than 84 million stars in the central parts of the Milky Way - ten times more than previously observed.

It has also found a large number of faint red dwarf stars which are prime candidates around which to search for small exoplanets - planets outside the solar system that may be Earth-like.

This treasure trove of information about the structure and content of the Milky Way is one of the biggest astronomical images ever produced and provides an incredible, zoomable view of the central part of our galaxy and is so large that, if printed with the resolution of a typical book, it would be 9 metres long and 7 metres tall.

Scroll down to watch this awesome video, its funny, we/they can send a probe and stuff into space and take real nice pictures of the Galaxy and Milky Way, and all sorts of wonderful phenomenon out there in the far reaches of space.

But when it comes to looking deep down into our own oceans/seas we/they are so limited in their technology that we have absolutely no clue as to how our world works. YEAH RIGHT !!!!!!!!!!!!!!!!!!!!!!

Enjoy

NASA'S CASSINI SEES LARGE BURP ON SATURN AFTER LARGE STORM

pia12829-640.jpg

These red, orange and green clouds (false color) in Saturn's northern hemisphere indicate the tail end of a massive storm that started in December 2010. Even after visible signs of the storm started to fade, infrared measurements continued to reveal powerful effects at work in Saturn's stratosphere. Image credit:NASA/JPL-Caltech/Space Science Institute

"October 25, 2012

PASADENA, Calif. -- NASA's Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet's upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought.

Data from Cassini's composite infrared spectrometer (CIRS) instrument revealed the storm's powerful discharge sent the temperature in Saturn's stratosphere soaring 150 degrees Fahrenheit (83 kelvins) above normal. At the same time, researchers at NASA's Goddard Spaceflight Center in Greenbelt, Md., detected a huge increase in the amount of ethylene gas, the origin of which is a mystery. Ethylene, an odorless, colorless gas, isn't typically observed on Saturn. On Earth, it is created by natural and man-made sources.

Goddard scientists describe the unprecedented belch of energy in a paper to be published in the Nov. 20 issue of the Astrophysical Journal.

"This temperature spike is so extreme it's almost unbelievable, especially in this part of Saturn's atmosphere, which typically is very stable," said Brigette Hesman, the study's lead author and a University of Maryland scientist who works at Goddard. "To get a temperature change of the same scale on Earth, you'd be going from the depths of winter in Fairbanks, Alaska, to the height of summer in the Mojave Desert."

First detected by Cassini in Saturn's northern hemisphere on Dec. 5, 2010, the storm grew so large that an equivalent storm on Earth would blanket most of North America from north to south and wrap around our planet many times. This type of giant disturbance on Saturn typically occurs every 30 Earth years, or once every Saturn year."

THE COX EFFECT AND THE HEALTH & SAFETY REGULATIONS

Professor Brian Cox formerly of the hit band D-Ream, was told by BBC bosses he couldn't listen to a newly discovered ?  planet, in case " Aliens " swore on live tv. " is this a joke script " !! " they just have to be kidding right " !!

Editorial Guidelines my arse.

The Planet : THREAPLETON HOLMES B was " discovered " by amateur stargazers during a project on the BBC 2 show.

He told BBC 6 Music: 'We decided that we’d point the [move]Jodrell Bank Telescope[/move] at the planet that had been discovered by these two viewers and listen because no one had ever pointed a radio telescope at it and you never know.

'The BBC actually said, ‘But you can’t do that because we need to go through the regulations and health and safety and everything in case we discover a signal from an alien civilisation’.'

He told Shaun Keaveny’s radio breakfast show: 'You mean we would discover the first hint that there is other intelligent life in the universe beyond Earth, live on air, and you’re worried about the health and safety of it?

'It was incredible. They did have guidelines. Compliance.'

A pair of amateur British stargazers discovered the new planet – for only the THIRD TIME  in history.

Chris Holmes and Lee Threapleton spotted the new world during a project to find planets beyond our solar system publicised by Cox in his Stargazing Live series.

They made the discovery after spotting changes in light patterns in an image from Nasa’s Kepler space telescope.

The unusual patterns suggested a planet appears to be orbiting a sun called SPH10066540, which lies between 600 and 3,000 light years away, is thought to be gaseous, and around the size of Neptune.

Best Meteor Shower of the Year Coming in December

Dec. 1, 2012

geminid_360_279.jpgThis year's Geminid meteor shower will peak on the night of December 13-14, and are the best meteor shower of the year for northern hemisphere viewers. Photo: Wally Pacholka/AstroPics.com via NASA

David Huestis, GoLocalProv Astronomy Contributor

"Mild comfortable nights of observing are now behind us. As we approach the Winter Solstice on December 21 at 6:12am (the earliest date and time for this astronomical event since 1896), our days grow shorter while the nights grow longer. Amateur astronomers like the early sunsets and the longer nighttime skies, but the cold temperatures can shorten one’s observing session quite effectively.

However, unless we get slammed with frequent and fast moving weather fronts during meteorological winter (December thru February), the skies can be very clear and transparent. For those of you who own telescopes of any size should take that opportunity to focus your instruments on the planet Jupiter. On December 1, this Jovian world will be at its closest distance to the Earth. Though still just over 378,000,000 miles away, Jupiter and his four Galilean moons reveal a lot of detail to even a casual observer using a telescope.

On that date this fifth planet from the Sun can be found to the left of the Hyades asterism in Taurus, and almost five degrees from Aldebaran, the red star that marks the eye of the bull.

Geminid Meteor Shower

While Jupiter will be observable for the next several months, the upcoming Geminid meteor shower will peak on the night of December 13-14 (Thursday night to Friday morning). The Geminids are currently the best meteor shower of the year for northern hemisphere viewers, and the New Moon will not be present to brighten the sky.

Therefore, from a dark sky location an observer should potentially observe 60+ meteors per hour at peak, which is predicted to occur sometime between midnight and 4:00am EST. But for those of you who don’t wish to observe into the wee hours of the morning, the Geminids do provide observers an opportunity to see a decent display during the pre-midnight hours."

NASA Voyager 1 Encounters New Region in Deep Space

Krimigis-1pia16483-43.gif

"Plasma Flow Near Voyager 1

This artist's concept shows plasma flows around NASA's Voyager 1 spacecraft as it approaches interstellar space. Voyager 1's low-energy charged particle instrument detects the speed of the wind of plasma, or hot ionized gas, streaming off the sun. It detected the slowing of this wind, also known as the solar wind, to zero outward velocity in a region called the stagnation region. Scientists had expected that the solar wind would turn the corner as it felt the pressure of the interstellar magnetic field and the interstellar wind flow. But that has not happened so far, so it is not clear what should be expected once the spacecraft reaches interstellar space.

Voyager 1 crossed a shockwave known as the termination shock in 2004. At the termination shock, the solar wind slows down abruptly from supersonic speeds. The heliopause is the boundary between the bubble of charged particles around our sun - known as the heliosphere - and interstellar space. Its location is still a mystery. "

NASA: Strange Object Debris Coming, Will Hit Earth December 13th and 14th

Dec. 2, 2012

The Geminid meteor shower peaks on Dec. 13th and 14th when Earth runs through a stream of debris from a strange object that some astronomers are calling a “rock comet  <<<a rock comet..ok then..

"The 2012 Geminid meteor shower peaks on the night of Dec. 13-14, The Geminids are a unique meteor shower in that their identified parent body is not a comet, but what seems to be an asteroid! Of the meteor showers with known parent bodies studied by meteor scientists, the Geminids are the only shower to have an asteroidal parent body; all others have a cometary origin. 3200 Phaethon measures 5.10 km in diameter which increases the ‘unique’ factor; considering the amount of debris we see, we would expect Phaethon to be a much larger body! "

snip

"In 2009 the NASA spacecraft STEREO-A observed 3200 Phaethon to brighten by a factor of two, quite unexpectedly. This brightening at perihelion was likely due to a release of dust from the object, possibly due to heating and cracking of the surface rocks as Phaethon came close to the Sun. That brings us to the fourth theory, that Phaethon is a rock comet. The problem with this theory is that it doesn’t account for the amount of dust in the Geminid stream.

So what it comes down to is that the Geminid parent object is a mystery"

Will our solar system cross the galactic plane on December 21, 2012?

Bruce McClure Dec 08, 2012

Will our solar system cross the plane of our Milky Way galaxy in 2012? No. The solar system will not cross the galactic plane on December 21, 2012 – or on any other date in 2012 – or anytime soon. Sure, our Milky Way galaxy is flat and round, like a pancake. And yes, the sun does weave in and out of the galaxy’s flat plane. However, astronomers have determined that we’re currently moving away from, not toward the galactic plane. By astronomers’ estimates, our solar system last crossed the plane of the Milky Way galaxy some 3 million years ago. We won’t do so again for another 30 million years.

This video is from Morehead Planetarium / Science360 in Chapel Hill, North Carolina. It’s one of a series of excellent videos by Morehead attempting to answer the many wild, crazy, improbable and false doomsday scenarios related to December 2012. Thank goodness this month is finally here. Soon it’ll be January. See you in 2013!

The Labor of Hercules A

DEC 10, 2012

By Phil Plait

"Black holes may be the most ironic objects in the Universe. They are objects with gravity so fierce that if you venture too close, literally no force in the Universe can prevent you from falling in. Not even light can escape, which is why we call them what we do.

Yet they also power the brightest objects in the Universe. As matter falls in, it forms a disk just outside the black hole that gets infernally hot, blasting out radiation bright enough that it can be seen across the Universe. Not only that, due to forces in the disk like friction and magnetism ramped up to mind-numbing intensities, this disk can focus and blast out two incredibly powerful beams of matter and energy which scream out into space, forming structures both vast and beautiful … like the ones seen in the galaxy Hercules A:"

Seriously, grab the embiggened version of that. It’s stunning. I’m using it as my computer’s desktop image, in fact. There’s also an incredible 5000 x 3500 pixel version.

In the heart of the galaxy Hercules A is a monster black hole: It’s about 600 times as massive as the black hole in the center of our Milky Way, making it about 2.5 billion times the Sun’s mass. It’s one of the largest known black holes in the Universe, so big we call it "supermassive."

alert massive breaking news of a black hole explosion

Dec. 17, 2012

http://www.youtube.com/watch?feature=player_embedded&v=i0XdPLi7x0M#!

Mr. McMaverick Star

Published on Dec 17, 2012

The light of the explosion was detected around July by NASA of a super novi caused by a black hole detected around the centre of our galaxy in the sagitarrius sagi A for short, it was a massive, massive explosion and the thing is this if the light was detected or received by NASA spacecraft around July, then it is likely six months on from then cosmic particles x rays are inbound any time now due to the slight variation in speed of particles and the lesser speed of cosmic rays with regard to the speed of light. I will show you the official 3 photos taken by NASA of the black hole gobbling up a star and showing you the explosion before it happens, as it happens, and after it has happened. You will have to call back within 8 hrs of this video due to the length of time it takes to upload them, this is ground breaking news and all too relevant to the time and predictions made by the mayans, i cannot emphasise to you guys how big this is. Best Gene

ps This event that NASA has seen and photographed happened thousands of yrs ago or even longer, i want you to think about how long it takes light to travel from the centre of our galaxy to the position where our solar system is in the spiral arm, thats why NASA knew what was coming next 4 yrs ago guys or probably longer.

Monster Outflows Pouring Out Of Milky Way’s Center

January 2, 2013

Mellinger (Central Michigan University); scientific imager, E. Bressert (CSIRO)

Lee Rannals for redOrbit.com – Your Universe Online

"Astronomers using CSIRO’s 210-feet Parkes radio telescope in eastern Australia have found monstrous outflows of charged particles coming from the center of our galaxy.

The researchers said that the outflows contain an extraordinary amount of energy, reaching about a million times the energy of an exploding star.

snip 

“They are not coming in our direction, but go up and down from the galactic plane,” said CSIRO’s Dr. Ettore Carretti. “We are 30,000 light-years away from the galactic center, in the plane. They are no danger to us.”

snip 

Astronomers said the outflows stretch about two-thirds across the sky from horizon to horizon, and correspond to a “haze” of microwave emission previously spotted by the WMAP and Planck space telescopes.

These telescopes did not provide enough evidence to indicate definitively the source of the radiation they detected, but the new Parkes observations do.

“The options were a quasar-like outburst from the black hole at the galactic center, or star-power — the hot winds from young stars, and exploding stars,” said team member Dr. Gianni Bernardi of the Harvard-Smithsonian Center for Astrophysics. “Our observations tell us it’s star-power.”

What's going on around Andromeda? Curious structure puzzles scientists.

Thirteen dwarf galaxies are playing a cosmic-scale game of Ring Around Andromeda, forming an enormous structure astronomers have never seen before and are hard-pressed to explain with current theories of how galaxies form and evolve.

0104-Andromeda-dwarf-galaxy.jpg_full_380.jpg

According to current theories, the small galaxies, which contain as many as a few tens of billions of stars each, should be randomly arranged around the Andromeda galaxy.

Instead, they orbit Andromeda within a plane more than 1 million light-years across and about 30,000 light-years thick.

"(Phys.org)—The surprising discovery of a massive outburst in a neighboring galaxy is giving astronomers a tantalizing look at what likely is a powerful belch by a gorging black hole at the galaxy's center. The scientists were conducting a long-term study of molecules in galaxies, when one of the galaxies showed a dramatic change.

"The discovery was entirely serendipitous. Our observations were spread over a few years, and when we looked at them, we found that one galaxy had changed over that time from being placid and quiescent, to undergoing a hugely energetic outburst at the end," said Robert Minchin, of Arecibo Observatory, who presented the research."

snip

"The astronomers used a network called the High Sensitivity Array (HSA), composed of the NSF's Very Long Baseline Array (VLBA), a continent-wide system of ten radio telescopes ranging from Hawaii to the Virgin islands; the Arecibo Telescope; the NSF's 100-meter Green Bank Telescope in West Virginia; and the 100-meter Effelsberg Radio Telescope of the Max Planck Institute for Radio Astronomy in Germany."

"Astronomers are carefully watching a gas cloud in our own Milky Way Galaxy that is expected to fall into our Galaxy's central black hole in the middle of this year."

On February 15, 2013, an asteroid will come close enough to Earth to knock satellites out of orbit

Near Earth Asteroid (NEA) 2012 DA14 has its annual flyby of the earth on February 15, 2013. Its projected orbit, according to NASA, will bring it well within the orbits of geosynchronous satellites currently orbiting our planet. NASA has indicated that there is no danger of this asteroid impacting our planet, however they have not ruled out our gravity changing the asteroids orbital pattern.  Changing the orbital pattern??

images?q=tbn:ANd9GcTb4sG7MpWL_C4wns3-RcoYHj0r8BtvaUzxS5sI8tmRqM-fRbOy

With Near Earth Asteroid 2012 DA 14?s flyby falling somewhere in between geosynchronous satellite orbit, and objects orbiting in a Medium Earth Orbit pattern, the potential for this NEO impacting other objects orbiting our planet appears to be almost guaranteed. Could one of these objects be impacted by the asteroid and then be propelled back into our atmosphere?

Asteroid Apophis to whiz past Earth tonight -- and return for more in 2036

By Tariq Malik

Published January 09, 2013

A European space telescope has captured new images of the huge asteroid Apophis, revealing that the potentially hazardous object is actually bigger than previously thought — and you have a chance to see the space rock yourself in two free webcasts tonight.

Asteroid Apophis has long been billed as a "doomsday asteroid" because of a 2004 study that predicted a 2.7 percent chance of the space rock hitting Earth when it passes within 22,364 miles of the planet in April 2029, European Space Agency officials said. Later studies proved, however, that the asteroid poses no threat to Earth during that flyby, but astronomers continue to track the object since it will make another pass near Earth in 2036."

Scientists have discovered that a barred spiral galaxy located 212 million light-years from the Earth is the largest-known spiral, measuring five times the size of our Milky Way galaxy.

Using archival data from NASA’s Galaxy Evolution Explorer (GALEX) mission, scientists found that measuring tip-to-tip across its two outsized spiral arms, NGC 6872 spans more than 522,000 light-years, making it more than five times the size of our Milky Way galaxy.
