The Sun has undergone a \\\"complete field reversal,\\\" with its north and south poles changing places as it marks the midpoint of Solar Cycle 24. Experts say that the reversal of the Sun\\\'s magnetic field is, literally, a big event and it is a regular part of the solar cycle. While it may seem like the event could have catastrophic repercussions for the galaxy, its effects are actually more subtle, mostly interfering with space exploration. Some researchers say cosmic rays are a danger to astronauts and space probes and might affect the cloudiness and climate of Earth. NASA has released a visualization of how the switch occurs. Beginning in 1997 and ending in 2013, it shows the green positive polarity switching with the purple negative polarity. Solar Cycle 24 has been viewed as quite unpredictable. First, it came late by about a year, with extremely low activity recorded throughout 2009. This prompted astronomers to shift a predicted 2012 peak to 2013.

Representative of the International Committee of the Red Cross Peter Stoeker visited Iranian diplomat Jalal Sharafi in a hospital in Tehran on Tuesday and witnessed in person the traces of severe physical tortures on his body from head to toe. Sharafi - the second secretary of the Iranian embassy in Baghdad - was abducted in southeastern Baghdad on February 4 by a group connected to the Iraqi Defense Ministry which operates under the supervision of the U.S. forces in Iraq. He was released on April 3. In the hospital where Sharafi was also visited by Iraq ambassador to Tehran -Mohamed Majid Al-Sheikh- Stoeker observed holes drilled in Sharafis feet fractures of the nose and neck - some deep bruises on his back - and evidence of a tear to his ear drum and bleeding in the alimentary canal. Sharafi told the Red Cross representative that he had undergone horrific torturing during the first 15 days of his arrest. He was later transferred by an ambulance on a wheelchair to the Foreign Ministry building to attend a news conference with the domestic and foreign reporters and photographers.He told the reporters that during his captivity - he was repeatedly tortured and interrogated about Irans role in Iraq. He said his kidnappers - who spoke in English and Arabic - were in constant contact with their chiefs through walkie-talkies while abducted him in southeastern Baghdad. In the first four or five days an eight-person group regularly beat me up day and night with a wire. He said he was asked - why Iran helps Islamic groups in Iraq and what those groups are. Why Iran supports the Maliki government and the Iraqi people. Are there any secret relations between them... Why do you help the Sunni scholars - and asked some questions about the detained Iranian diplomats in Arbil -northern Iraq- the relations between Iraqi Kurdish leader Masoud Barzani and Iraqi president Jalal Talabani with Iran and in Iran which persons purchase uranium.... He added -At the last stage of my interrogation somebody who introduced himself as an American and a mediator between the U.S. embassy and the person in charge of my case came to me and since I could not understand English the words were translated into Arabic.Mr. Stoeker said his organization had been unable to find him in Iraq.

The Islamic Republic of Iran successfully launches its second satellite christened Rassad (Observation) into the earth's orbit. The satellite, which is the country's first such imaging device, was launched by the Safir-e-Rassad satellite carrier on Wednesday thanks to Iranian aerospace scientists and experts' endeavor, IRNA reported. Despite its 15.3-kilogram weight, which puts it under the category of the micro-satellites, Rassad has all features of a big satellite. It has undergone all the stages required for its designing, manufacturing, assembly, test and preparation for launch inside the country. It will orbit the earth at an altitude of 260 kilometers 15 times every 24 hours. Its mission is to take images of the earth's surface and relay them to the earth-based stations together with telemetric information. The satellite is equipped with solar panels and uses solar energy to work. Iran launched its first domestically-produced satellite Omid (Hope) in 2009, which made it the ninth country to develop satellite launch capability. Tehran also plans to launch the country's first manned mission to space by 2019.
