ESA Hubble - Dramatic Change Spotted on Faraway Planet



Published on Jun 28, 2012 by camillasdo

Dr. J (aka Dr. Joe Liske) presents the latest discovery about HD 189733b, an exoplanet that has been repeatedly studied by Hubble.

Observations taken in 2011 using Hubble and the Swift satellite showed a flare from the planet's parent star scorching the upper atmosphere and driving it off into space.

A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet to that of the sun.

....Er, NASA, why have you left out the MOONS ORBIT in this Video?

The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 60 in the Spring of 2013. We are currently over three years into Cycle 24. The current predicted size makes this the smallest sunspot cycle in about 100 years.


The prediction method has been slightly revised. The previous method found a fit for both the amplitude and the starting time of the cycle along with a weighted estimate of the amplitude from precursor predictions (polar fields and geomagnetic activity near cycle minimum). Recent work [see Hathaway Solar Physics; 273, 221 (2011)] indicates that the equatorward drift of the sunspot latitudes as seen in the Butterfly Diagram follows a standard path for all cycles provided the dates are taken relative to a starting time determined by fitting the full cycle. Using data for the current sunspot cycle indicates a starting date of May of 2008. Fixing this date and then finding the cycle amplitude that best fits the sunspot number data yields the current (revised) prediction.

The solar flare which erupted on March 7 was the most powerful eruption ever observed by Fermi's Large Area Telescope (LAT).

The flare, classified as X5.4, made the sun briefly the brightest object in the gamma-ray sky.

"For most of Fermi's four years in orbit, its LAT saw the sun as a faint, steady gamma-ray source thanks to the impacts of high-speed particles called cosmic rays," says Nicola Omodei, an astrophysicist at Stanford University in California. "Now we're beginning to see what the sun itself can do."

At the flare's peak, it was emitting gamma rays with two billion times the energy of visible light, or about four billion electron volts - easily setting a record for the highest-energy light ever detected during or immediately after a solar flare.

A flurry of solar activity in early March dumped enough heat in Earth's upper atmosphere to power every residence in New York City for two years. The heat has since dissipated, but there's more to come as the solar cycle intensifies.

NASA says it will hold a news conference at 1 p.m. EDT (6 p.m. GMT) on Thursday to reveal near-Earth asteroid findings and implications for future research. The briefing will take place at NASA Headquarters in Washington.

NASA’s Wide-field Infrared Survey Explorer (WISE) mission, launched in December 2009, captured millions of images of galaxies and objects in space. During the news conference, panelists will discuss results from an enhancement of WISE called Near-Earth Object WISE (NEOWISE) that hunted for asteroids.

The news conference panelists will include Lindley Johnson, Near-Earth Object program executive, NASA Headquarters, Washington; Amy Mainzer, NEOWISE principal investigator, NASA’s Jet Propulsion Laboratory, Pasadena, California; Tim Spahr, director, Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, Massachusetts; and Lucy McFadden, scientist, NASA’s Goddard Space Flight Center, Greenbelt, Maryland.

The conference takes place on the same week that a 13-metre-wide asteroid, named SE58, passed within 0.6 Lunar Distances of Planet Earth. SE58′s approach occured in the early hours of Tuesday 27 September 2011.

The NASA conference also coincides with an ESA (European Space Agency) seminar on Space Situational Awareness, which also be held on Thursday in Warsaw, Poland. Participants will include senior managers, policy-makers and scientists from ESA, ESA Member States, the EU, European institutions and international partner organisations.

For the first time, a spacecraft far from Earth has turned and watched a solar storm engulf our planet. The movie, released today during a NASA press conference, has galvanized solar physicists, who say it could lead to important advances in space weather forecasting.

“The movie sent chills down my spine,” says Craig DeForest of the Southwest Research Institute in Boulder, Colorado. "It shows a CME swelling into an enormous wall of plasma and then washing over the tiny blue speck of Earth where we live. I felt very small.”



A wide-angle movie recorded by NASA's STEREO-A spacecraft shows a solar storm traveling all the way from the sun to Earth and engulfing our planet.

CMEs are billion-ton clouds of solar plasma launched by the same explosions that spark solar flares. When they sweep past our planet, they can cause auroras, radiation storms, and in extreme cases power outages. Tracking these clouds and predicting their arrival is an important part of space weather forecasting.

“We have seen CMEs before, but never quite like this,” says Lika Guhathakurta, program scientist for the STEREO mission at NASA headquarters. “STEREO-A has given us a new view of solar storms.”

NASA will hold a press conference Thursday (Aug. 18) to discuss "new details about the structure of solar storms and the impact they have on Earth," space agency officials said in a statement.

The briefing this week will review new observations from several NASA spacecraft, including the Solar Terrestrial Relations Observatory (Stereo), that currently keep a close eye on the sun, agency officials said in the statement released today (Aug. 16).

Thursday's briefing will be held at NASA's headquarters in Washington and will include presentations from several space weather experts. They include:

The news briefing will begin at 2 p.m. EDT (1800 GMT) and will be broadcast live on the NASA TV cable channel, as well as webcast on the agency's NASA TV website.

The sun is currently in an active phase of its 11-year solar weather cycle (the current season is called Solar Cycle 24) and has erupted with several major flares in recent weeks. The solar cycle will peak in 2013, NASA scientists have said.

Dear All

Here is a new article based on revelations given to me this morning by an anonymous whistleblower showing NASA is rigging the data in sunspots.

Thanks,

John O'Sullivan

As Earth enters deepest solar minimum in centuries NASA caught hiding sunspot data to prop up dying global warming cult. Inconvenient new ice age imminent.

A solar scientist insider who wishes to remain anonymous gives us the scoop that government officials are falsifying solar data to suit a political agenda. Below is his damning indictment of how deeply entrenched and desperate is the climate fraud. We see how observational data is being deliberately faked to hide the decline in sunspot activity; an event which independent scientists say could trigger a new ice age if it is prolonged.



The source, who fears losing his position if identified reveals, “The fact is for years we have been watching the magnetic fields wane both here on Earth and on the Sun.”

But NASA has conspired with advocates of the man-made global warming cult to 'hide the decline' which would make a mockery of their trumped claims mankind has created a new and warmer Anthropocene Climatic period.

Continued Rate of Cooling to Cause New Ice Age

Our nameless expert explains that since the 1990's and into the 21st century magnetic fields have dropped by about 50 gauss per year. No one denies that in itself, this is not a remarkable drop if it were to be soon reversed. However, if such a trend continues for a decade or more then the fears of solar scientists that we are entering a new Ice Age will be realized with potentially devastating consequences for life of Earth.
