Our Galaxys Magnetic Field from Planck

What does the magnetic field of our Galaxy look like? It has long been known that a modest magnetic field pervades our Milky Way Galaxy because it is seen to align small dust grains that scatter background light. Only recently, however, has the Sun-orbiting Planck satellite made a high-resolution map of this field. Color coded, the 30-degree wide map confirms, among other things, that the Galaxy's interstellar magnetism is strongest in the central disk. The revolution of charged gas around the Galactic center creates this magnetism, and it is hypothesized that viewed from the top, the Milky Way's magnetic field would appear as a spiral swirling out from the center. What caused many of the details in this and similar Planck maps -- and how magnetism in general affected our Galaxy's evolution -- will likely remain topics of research for years to come.

CDC Gov Doc: January is Birth Defects Prevention Month

Did you know that every 4 ½ minutes a baby in the United States is born with a major birth defect? January is National Birth Defects Prevention Month, a time to raise awareness about birth defects and of the steps that can be taken to prevent them. While not all birth defects can be prevented, there are things you can do to get ready for a healthy pregnancy.

  • In addition to eating a healthy diet, be sure to consume 400 micrograms of folic acid every day before and during early pregnancy.

  • See a health care professional regularly. Talk to them about taking any medicine, including prescription and over-the counter medicines and dietary or herbal supplements, and take only what is needed. Talk to your health care provider before starting or stopping any medication.

  • Work to get health conditions, like diabetes, in control before becoming pregnant, and keep them in good control during pregnancy.

  • Try to reach and maintain a healthy weight before becoming pregnant.

  • Avoid alcohol and tobacco during pregnancy.

Sounding Rockets Launch Into an Aurora

The interaction of solar winds and Earth’s atmosphere produces northern lights, or auroras, that dance across the night sky and mesmerize the casual observer. However, to scientists this interaction is more than a light display. It produces many questions about the role it plays in Earth’s meteorological processes and the impact on the planet’s atmosphere. To help answer some of these questions, NASA suborbital sounding rockets carrying university-developed experiments -- the Mesosphere-Lower Thermosphere Turbulence Experiment (M-TeX) and Mesospheric Inversion-layer Stratified Turbulence (MIST) -- were launched into auroras from the Poker Flat Research Range in Alaska. The experiments explore the Earth’s atmosphere’s response to auroral, radiation belt and solar energetic particles and associated effects on nitric oxide and ozone. This composite shot of all four sounding rockets for the M-TeX and MIST experiments is made up of 30 second exposures. The rocket salvo began at 4:13 a.m. EST, Jan. 26, 2015. A fifth rocket carrying the Auroral Spatial Structures Probe remains ready on the launch pad. The launch window for this experiment runs through Jan. 27.

Turnabout Is Fair Play

At Chancellorsville in 1863, a Confederate sniper was having fun taking down any Union soldiers who got too close. That is, until a Union sniper got a bright idea.

First he took off his cap, and shoved it over the earthwork. Of course, Johnnie Reb let go at it, thinking to kill the careless man under it. His bullet struck into the bank, and instantly our sharpshooter ran his ramrod down the hole made by the Johnnie’s ball, then lay down on his back and sighted along the ramrod. He accordingly perceived from the direction that his game was in the top of a thick bushy elm tree about one hundred yards in the front. It was then the work of less than a second to aim his long telescopic rifle at that tree and crack she went. Down tumbled Mr. Johnnie like a great crow out of his nest, and we had no more trouble from that source.

January 27th 1973: Paris Peace Accords

On this day in 1973, the Paris Peace Accords were signed in the French capital, ending U.S. involvement in the Vietnam War. American involvement in the country went back to the 1950s, with Cold War fears of the region falling to communism leading a series of Presidents to steadily increase the presence of American advisers in Vietnam. Vietnam successfully achieved independence from the colonial French in 1954, which also resulted in the division of the country between the communist North under Ho Chi Minh, and the South under U.S.-backed Ngo Dinh Diem. The two sections soon broke out in fighting, and in August 1964 the United States fully committed to the war after the Gulf of Tonkin incident. This was when the North Vietnamese allegedly fired on American ships in the gulf, which resulted in Congress passing a resolution allowing the President to intervene in the war to counter the communists. The high casualty rates of American soldiers, and tales of horrific acts of violence like the My Lai massacre in 1968, prompted mass protests against the war in the United States. This increased opposition to the presidency of Lyndon Johnson, who declined to run for another term in 1968 and was succeeded by Richard Nixon. Nixon initially expanded the war into neighboring Laos and Cambodia, but then began to gradually withdraw troops from the war that had reached an unwinnable and bloody stalemate. The 1973 settlement, known as ‘An Agreement Ending the War and Restoring Peace in Vietnam’, included a cease-fire throughout Vietnam, as well as the withdrawal of U.S. forces. U.S. Representative Henry Kissinger and North Vietnamese Le Duc Tho were awarded the Nobel Peace Prize for their efforts in Paris, though the latter refused the award. However the fighting in Vietnam continued until 1975, when Saigon fell to the North Vietnamese Army, and the nation was united under communist rule.
