AURORAS UNDERFOOT:
Earth orbit is a great place to watch geomagnetic storms. On July 14th, astronauts onboard the International Space Station (ISS) witnessed a broad curtain of green auroras over the southern hemisphere. This is what aurora australis looks like from space:
The display was caused by a solar wind stream which hit Earth's magnetic field on July 12th. Note to astronauts: Another solar wind stream is heading for Earth, due to arrive on July 19th-20th. The crew of Atlantis should remain alert for auroras.

MAN-MADE COMET CRATER:
In July 2005, NASA's Deep Impact spacecraft dropped an 820-lb copper projectile onto the surface of Comet Tempel 1. Almost six years later, NASA finally saw the impact crater. On Valentine's Day 2011, long after the dust had cleared, Stardust-NExT flew past Tempel 1 and photographed the impact site:

RETURN OF JUPITER'S MISSING STRIPE:
The revival of Jupiter's South Equatorial Belt (SEB), missing for nearly a year, is now well underway. The roiling, turbulent disturbance that heralds the brown stripe's full return stretches almost halfway around the giant planet. "Here is a projection map showing the revival on Nov. 29th," says amateur astronomer Wayne Jaeschke of West Chester, Pennsylvania. Note the region bracketed by arrows:

LIGHT BRIDGE:
The primary core of sunspot 1236 is divided by a brilliant canyon of light--also known as a "light bridge"--measuring some 20,000 km from end to end. Amateur astronomer Howard Eskildsen photographed the phenomenon from his backyard observatory in Ocala, Florida. Follow the arrow:
The nature of light bridges is not fully understood. They often herald the break-up of a sunspot. Some research suggests that magnetic fields at the base of a light bridge are busy cross-crossing and reconnecting--the same explosive process that sparks solar flares. Does this mean the primary core of sunspot 1236 will explode? Or quietly fall apart? No one can say. Readers with solar telescopes are encouraged to monitor developments.

LAST PICTURE OF ATLANTIS IN SPACE:
On Thursday, July 21st, space shuttle Atlantis landed at NASA's Kennedy Space Center, wrapping up the final mission of NASA's space shuttle program. At 08:27:48 UT, just 21 minutes before the deorbit burn, astrophotographer Thierry Legault captured what might be the last picture of Atlantis in space--and it was a solar transit:
The crew of the International Space Station photographed Atlantis even closer to landing, but the orbiter was no longer technically in space. It was reentering Earth's atmosphere:

WHAT LIES INSIDE JUPITER?
Jupiter's swirling clouds can be seen through any department store telescope. With no more effort than it takes to bend over an eyepiece, you can witness storm systems bigger than Earth navigating ruddy belts that stretch hundreds of thousands of kilometers around Jupiter's vast equator. It's fascinating.
It's also vexing. According to many researchers, the really interesting things--from the roots of monster storms to stores of exotic matter--are located at depth. The clouds themselves hide the greatest mysteries from view.
NASA's Juno probe, scheduled to launch on August 5th, could change all that. The goal of the mission is to answer the question, What lies inside Jupiter?
"Our knowledge of Jupiter is truly skin deep," says Juno's principal investigator, Scott Bolton of the SouthWest Research Institute in San Antonio, TX. "Even the Galileo probe, which dived into the clouds in 1995, penetrated no more than about 0.2% of Jupiter??s radius."
There are many basic things researchers would like to know—like how far down does the Great Red Spot go? How much water does Jupiter hold? And what is the exotic material near the planet's core?
Juno will lift the veil without actually diving through the clouds. Bolton explains how: "Swooping as low as 5000 km above the cloudtops, Juno will spend a full year orbiting nearer to Jupiter than any previous spacecraft. The probe's flight path will cover all latitudes and longitudes, allowing us to fully map Jupiter's gravitational field and thus figure out how the interior is layered."
Jupiter is made primarily of hydrogen, but only the outer layers may be in gaseous form. Deep inside Jupiter, researchers believe, high temperatures and crushing pressures transform the gas into an exotic form of matter known as liquid metallic hydrogen--a liquid form of hydrogen akin to the slippery mercury in an old-fashioned thermometer. Jupiter's powerful magnetic field almost certainly springs from dynamo action inside this vast realm of electrically conducting fluid.

"Juno's magnetometers will precisely map Jupiter's magnetic field," says Bolton. "This will tell us a great deal about the planet's inner magnetic dynamo [and the role liquid metallic hydrogen plays in it]."
Juno will also probe Jupiter's atmosphere using a set of microwave radiometers.
"Our sensors can measure the temperature and water content at depths where the pressure is 50 times greater than what the Galileo probe experienced," says Bolton.
Jupiter's water content is of particular interest. There are two leading theories of Jupiter's origin: One holds that Jupiter formed more or less where it is today, while the other suggests Jupiter formed at greater distances from the sun, later migrating to its current location. (Imagine the havoc a giant planet migrating through the solar system could cause.) The two theories predict different amounts of water in Jupiter's interior, so Juno should be able to distinguish between them—or rule out both.
Finally, Juno will get a grand view of the most powerful Northern Lights in the Solar System.
"Juno's polar orbit is ideal for studying Jupiter's auroras," explains Bolton. "They are really strong, and we don't fully understand how they are created."
Unlike Earth, which lights up in response to solar activity, Jupiter makes its own auroras. The power source is the giant planet's own rotation. Although Jupiter is ten times wider than Earth, it manages to spin around 2.5 times as fast as our little planet. As any freshman engineering student knows, if you spin a magnet—and Jupiter is a very big magnet—you've got an electric generator. Induced electric fields accelerate particles toward Jupiter's poles where the aurora action takes place. Remarkably, many of the particles that rain down on Jupiter's poles appear to be ejecta from volcanoes on Io. How this complicated system actually works is a puzzle.
It's a puzzle that members of the public will witness at close range thanks to JunoCam—a public outreach instrument modeled on the descent camera for Mars rover Curiosity. When Juno swoops low over the cloudtops, JunoCam will go to work, snapping pictures better than the best Hubble images of Jupiter.
"JunoCam will show us what you would see if you were an astronaut orbiting Jupiter," says Bolton. "I am looking forward to that in 2016."

That is very cool. What else do you remember? Were you scared? Indifferent?
Had you been reading or watching science related stuff?

Don't laugh at me, because I can't control the dreams I'm in lol. So they might not make a lot of sense to you. To me it made perfect sense while in the dream.
I remember there being a huge crater on what would be the north pole, except it was pushed outwards instead of sunk inwards. I remember some older guy telling me how the core of the Earth was just missing. I walked outside and I said that I could feel that the Earth wasn't rotating anymore. I don't remember who I was talking to, but I told someone they need to lay some type of explosive(s) around the rim of that huge crater. To blow it up and make it sink to the core of the Earth, in order to fix it. I don't remember what happened after that though :/, quite strange dream in my opinion. Yes I was a little scared but I still remained calm.click to expand
Hey man thats awesome. It was like you were some Geological-Engineer with a PHD in some real smart shit and knew what to do.....blow yourself up. hahahaha.
But seriously, you just came up with a short sci-fi story all thanks to your brain. its a truly magnificent organ. Real cool man, thanks for sharing.

AUGUST 4th, 2011
STRONG SOLAR ACTIVITY:
For the third day in a row, active sunspot 1261 has unleashed a significant M-class solar flare. The latest blast at 0357 UT on August 4th registered M9.3 on the Richter Scale of Flares, almost crossing the threshold into X-territory (X-flares are the most powerful kind). The number of energetic protons around Earth has jumped nearly 100-fold as a result of this event.
The eruption propelled a bright coronal mass ejection (CME)toward Earth recorded by the Solar and Heliospheric Observatory:

SUBSIDING STORM:
Earth's magnetic field is still reverberating from a CME strike on August 5th that sparked one of the strongest geomagnetic storms in years. Registering 8 on the 0 to 9 "K-index" scale of magnetic disturbances, the storm at maximum sparked auroras across Europe and in many northern-tier US states. Travis Novitsky sends this picture from Grand Portage, Minnesota:
The storm is subsiding now, but it could flare up again as gusty solar wind continues to buffet Earth's magnetic field. High-latitude sky watchers should remain alert for auroras.

Is Salty Water Flowing Seasonally On Mars?
There might be a lot of water in the upper three feet of Martian soil. That means there could be microbes with that water and those microbes might be releasing methane - at least one hypothesis for the methane replenishment mystery in the Martian atmosphere.

VENUS AND THE SOLAR STORM:
(Note: No planets were harmed in the production of this photo.)
Yesterday, the Solar and Heliospheric Observatory
a spectacular explosion on the sun that seemed to pass perilously close to Venus.
Did the cloudy planet survive?
Although Venus seems to be near the sun, the planet is actually more than 100 million kilometers away.
The two bodies are "in conjunction" this week as Venus moves almost directly behind the sun.
Because of this arrangement, more CME-Venus conjunctions are possible in the days ahead.

Cool pic wg.
It'd be nice to live somewhere close to an area without any light pollution.
Only seen the night sky a few times like that (both Hemispheres though😛), it's nuts what you can see in those conditions.
Pretty cool....i was wondering what the other stuff in the pic were and they are answered in this vid.
Just brilliant.
