NASA Image of the day, Mar 23rd ....[ 2210 ]
The latest NASA "Image of the Day" image.
.
This image taken by the Hubble Space Telescope in 2009 features Saturn with the rings edge-on and both poles in view, offering a stunning double view of its fluttering auroras.
-
Created by the interaction of the solar wind with the planet's magnetic field, Saturn's aurorae are analogous to the more familiar northern and southern lights on Earth.
.
At the time when Hubble snapped this picture, Saturn was approaching its equinox so both poles were equally illuminated by the sun's rays. At first glance the light show of Saturn's auroras appears symmetric at the two poles. However, astronomers discovered some subtle differences between the northern and southern auroras, which reveal important information about Saturn's magnetic field.
-
The northern auroral oval is slightly smaller and more intense than the southern one, implying that Saturn's magnetic field is not equally distributed across the planet; it is slightly uneven and stronger in the north than the south.

Libya Air-Strikes..[ 2209 ]
Air strikes silence Gaddafi guns at besieged city

TRIPOLI |
(Reuters) - Allied warplanes silenced Muammar Gaddafi's artillery and tanks besieging the rebel-held town of Misrata on Wednesday after an American admiral warned that the Libyan leader's armor was now in the cross-hairs.-
Breathing defiance, Gaddafi earlier said Western powers who carried out a fourth night of air strikes on Libya to protect civilians under a U.N. mandate were "a bunch of fascists who will end up in the dustbin of history."
-
Gaddafi's tanks had kept up the shelling of Misrata, killing dozens of people this week, and residents said a "massacre" was taking place with doctors treating the wounded in hospital corridors. Snipers killed five people on Wednesday, they said.
-
"The allied planes bombed twice so far. At 12:45 (2245 GMT Tuesday) this morning and then again less than two hours ago," a resident, Saadoun, told Reuters by telephone from Misrata.
-
"They (pro-Gaddafi forces) haven't fired a single artillery (round) since the air strike." Another resident said the strikes hit a base, south of Misrata, where Gaddafi forces were based.
Such precision bombing missions can be directed by long distance with electronic systems and sometimes use rebel agents in the target zone or special forces long-range reconnaissance patrols who guide the warplanes in.
-
At least two explosions were heard in the Libyan capital Tripoli before dawn on Wednesday on a fourth night of strikes, Reuters witnesses said. The roar of a warplane was heard above the city followed by a barrage of anti-aircraft gunfire.
Prior to the Misrata strikes, U.S. Rear Admiral Peg Klein said warplanes would be sent out to attack Gaddafi's tanks.
-
"Some of those cities still have tanks advancing on them to attack the Libyan people," said Klein, commander of the expeditionary strike group aboard the USS Kearsarge off Libya.
"We are authorized, and the president made the nexus between the Security Council resolution and what he considers our legal mandate to attack those tanks. So that is the type of target that our strike aircraft will go at."

ZINTAN RESIDENTS FEAR TANKS
Gaddafi forces resumed on Wednesday their bombardment of Zintan, another rebel-held town in west Libya, a resident said.
"Gaddafi's brigades started bombardment from the northern area half an hour ago. The bombardment is taking place now. The town is completely surrounded. The situation is very bad," the resident, Abdulrahman, told Reuters by telephone from the town.
-
"They are getting reinforcements. Troops backed with tanks and vehicles are coming. We appeal to the allied forces to come and protect civilians," he said.
While Western air power has grounded Gaddafi's warplanes and pushed back his forces from the brink of rebel stronghold Benghazi, his army has been besieging Libyan holdouts by rebels fighting to overthrow his 41-year rule.

The latest NASA "Image of the Day" image.
.
This swirling landscape of stars is known as the North America Nebula. In visible light, the region resembles North America, but in this new infrared view from NASA's Spitzer Space Telescope, the continent disappears. Where did the continent go?
.
The reason you don't see it in Spitzer's view is due, in part, to the fact that infrared light can penetrate dust whereas visible light cannot. Dusty, dark clouds in the visible image become transparent in Spitzer's view. In addition, Spitzer's infrared detectors pick up the glow of dusty cocoons enveloping baby stars.
.
Clusters of young stars (about one million years old) can be found throughout the image. Slightly older but still very young stars (about 3-5 million years) are also liberally scattered across the complex.
.
Some areas of this nebula are still very thick with dust and appear dark even in Spitzer's view and are likely to be the youngest stars in the complex (less than a million years old).

Russia's Heads disagree over Libya....[ 2208 ]
Medvedev rejects Putin 'crusade' remark over Libya
Dmitry Medvedev had been widely seen as being Mr Putin's man
,

Russia's President Dmitry Medvedev has said Prime Minister Vladimir Putin's description of the UN resolution on Libya is "unacceptable".
The rare rebuke came after Mr Putin said the resolution resembled "medieval calls for crusades".
-
Mr Medvedev said such comments could "lead to a clash of civilisations".
The UN resolution, which Russia abstained from voting on, authorised military action in Libya to protect civilians from pro-Gaddafi forces.
.
Mr Medvedev told Russian news agencies: "Under no circumstances is it acceptable to use expressions which essentially lead to a clash of civilisations, such as 'crusade' and so on.
"It is unacceptable. Otherwise, everything may end up much worse compared to what's going on now."
.
Mr Putin had said UN Security Council Resolution 1973, which was adopted on Thursday, was "defective and flawed" as it "allows for everything".
The resolution authorises "all necessary measures" to protect civilians in Libya, but Mr Putin said there was no logic in killing civilians to achieve that end.
,
He said he was worried at the ease with which decisions to use force in international affairs were being taken.
