Polar Mesospheric Clouds

NASA: A NASA satellite has captured the first occurrence this summer of mysterious shiny polar clouds that form 50 miles above Earth’s surface.
The first observations of these “night-shining” clouds by a satellite named “AIM” which means Aeronomy of Ice in the Mesosphere, occurred above 70 degrees north latitude on May 25. People on the ground began seeing the clouds on June 6 over Northern Europe. AIM is the first satellite mission dedicated to the study of these unusual clouds.
These mystifying clouds are called Polar Mesospheric Clouds, or PMCs, when they are viewed from space and referred to as “night-shining” clouds or Noctilucent Clouds, when viewed by observers on Earth. The clouds form in an upper layer of the Earth’s atmosphere called the mesosphere during the Northern Hemisphere’s summer season which began in mid-May and extends through the end of August and are being seen by AIM’s instruments more frequently as the season progresses. They are also seen in the high latitudes during the summer months in the Southern Hemisphere.
New Jupiter Impact Nearly Quarter of the Size of Earth

Sunspot 1024. First Sunspot of the New Solar Cycle.

Doomdaily: Sunspot 1024 is crackling with B- and C-class solar flares. The activity is so intense, astronomers can’t seem to take a picture of the sunspot without catching a flare in action.
Pete Lawrence sends this example from his backyard observatory in Selsey, UK:
“Active region 1024 is putting on a fantastic show,” says Lawrence. “The center of this region is incredibly bright and fluctuating.”
Solar observers haven’t seen an active region like this one in more than two years. It is big, complex, and rapidly growing: movie.
Asteroid Passes Within 41,000 Miles of Earth. Another Warning?
National Geographic: Sky-watchers in Asia, Australia, and the Pacific islands welcomed a surprise guest Monday: an asteroid that passed just 41,010 miles (66,000 kilometers) above Earth.
Discovered only days ago, asteroid 2009 DD45 zipped between our planet and the moon at 13:44 universal time (8:44 a.m. ET). The asteroid was moving at about 12 miles (20 kilometers) a second when it was closest to Earth.
“We get objects passing fairly close, or closer than this, every few months,” Timothy Spahr, director of the International Astronomical Union’s Minor Planet Center in Massachusetts, said in an email.
“Also, though, note these are only the ones that are discovered. Many more pass this close undetected”-as asteroid 2009 DD45 nearly did.
Astronomers didn’t notice the oncoming asteroid until February 28, when it showed up as a faint dot in pictures taken at the Siding Spring Observatory in Australia.
At that point the asteroid was already a mere 1.5 million miles (2.4 million kilometers) from Earth, and closing in fast.
Why do I get the feeling that this lastest close call is one of our final warnings to start looking out for these astroids and to have actionable plans for dealing with them. Finding an astroid like this one only days from potential impact is useless. Of course spending TRILLIONS on banks and wars makes much more sense then looking out for Extinction Level Events like an astroid impact such as this one could have been!
NASA’s Fermi Telescope Sees Most Extreme Gamma-Ray Blast Yet

NASA/FERMI: The first gamma-ray burst to be seen in high-resolution from NASA’s Fermi Gamma-ray Space Telescope is one for the record books. The blast had the greatest total energy, the fastest motions and the highest-energy initial emissions ever seen. (Center Image)
Gamma-ray emission from energies between 3,000
to more than 5 billion times that of visible light.
“We were waiting for this one,” said Peter Michelson, the principal investigator on Fermi’s Large Area Telescope at Stanford University. “Burst emissions at these energies are still poorly understood, and Fermi is giving us the tools to understand them.”
Gamma-ray bursts are the universe’s most luminous explosions. Astronomers believe most occur when exotic massive stars run out of nuclear fuel. As a star’s core collapses into a black hole, jets of material — powered by processes not yet fully understood — blast outward at nearly the speed of light. The jets bore all the way through the collapsing star and continue into space, where they interact with gas previously shed by the star and generate bright afterglows that fade with time.
Magnetic-Shield Cracks Found; Big Solar Storms in 2012

National Geographic: An unexpected, thick layer of solar particles inside Earth’s magnetic field suggests there are huge breaches in our planet’s solar defenses, scientists said.
These breaches indicate that during the next period of high solar activity, due to start in 2012, Earth will experience some of the worst solar storms seen in decades.
Data from NASA’s THEMIS satellite showed that a 4,000-mile-thick (6,437-kilometer-thick) layer of solar particles has gathered and is rapidly growing within the outermost part of the magnetosphere, a protective bubble created by Earth’s magnetic field.
Normally the magnetosphere blocks most of the solar wind, flowing outward from the sun at about a million miles (1.6 million kilometers) an hour.
