A simple view of gravity does not fully explain the distribution of stars in crowded clusters

(Phys.org)—Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the pull of gravity.

Tropical Cyclone Haruna (16S) in South Indian Ocean, is forecast to increase in intensity in the next 24 hours to a peak of 100 knots, gusting up to 125 knots. Increasing vertical wind shear and land interaction will begin to weaken the system in the next 24 hours.

According to latest report by Joint Typhoon Warning Center (JTWC), Tropical Cyclone Haruna is located approximately 380 nm southwest of Antananarivo, Madagascar, has tracked southeastward at speed of 03 knots, generating 7.6 meter-high (25-foot-high) waves. Animated infrared satellite imagery shows the system continued to deepen as it maintained a large and symmetrical 30-nm eye. Upper level analysis indicates the system is just to the west of an anticyclone in an area of low (05-10 knot) vertical wind shear and excellent radial outflow.

The second tropical depression of the northwestern Pacific Ocean season formed on February 19, 2013 and the system is soaking the central and southern Philippines. Early on February 19, 2013, the low pressure area designated as System 98W organized into a tropical depression and was renamed “02W.” Tropical Depression 02W formed south of Mindanao, the Philippines. TD02W is referred to locally in the Philippines as “Tropical Depression Crising.” TD02W is currently experiencing moderate vertical wind shear, as high as 20 knots (23 mph/37 km/h) which is keeping the depression from getting better organized. That is expected to change, however, once TD02W moves west...

PHOENIX (CBS5) - A 150-foot section of U.S. 89 south of Page that buckled and sunk four feet Wednesday might have been caused by a "geologic event," according to the Arizona Department of Transportation.

The road collapsed at mile post 526 just 2.5 miles north of the intersection with U.S. 89A, about 25 miles south of page, according to an ADOT spokesman. He said the incident was not related to the weather.

NASA has revealed the first radar video of an asteroid flyby that sent a space rock half the size of a football field buzzing by Earth last week.

 

The new asteroid flyby video, released today (Feb. 19), shows the asteroid 2012 DA14 as it headed away from Earth over the weekend. The asteroid zipped close by Earth on Friday (Feb. 15), when it approached closer to the planet than many communications satellites.

Heaven Letters Published on: February 21, 2013

 

God said:

Well, dear Children of Mine, what are you thinking of today? Where is your heart, and where is your mind? What are your thoughts on? What myriad of things are you thinking about?

Your heart and your mind are often in tandem. When you think of bills, for example, your heart may sink. And when you think of Me, your heart may rise. In Heaven, nothing is known as heart-sinking. In Heaven, only heart-singing is known.

In the same vein, in Heaven, in this Eternity of Heaven, death is not even thought of, and yet it is said that angels greet you when you leave your body and you come here, heart and soul. Angels do greet you, yet it is more like this: An angel sees you and says: “Happy to see you! Where have you been?”

A giant sunspot that's at least six times the diameter of Earth has formed on the sun in less than 48 hours, according to NASA.Sunspots form when the sun's magnetic fields rearrange and realign. They tend to be unstable and can lead to solar flares.

 


According to a news release, scientists from NASA's Solar Dynamics Observatory watched the sunspot rapidly grow on February 19 and 20. The agency says it could even be larger than six times the diameter of Earth "since the spot lies on a sphere not a flat disk."

MARQUETTE — A strong winter storm has dumped more than 20 inches of snow in parts of northern Michigan, forcing officials to close some roads and many schools in the Upper Peninsula.

State police say snowdrifts of up to 8 feet and 40-mph wind gusts led to the closing of a stretch of M-28 between Marquette and Munising, and it remained closed indefinitely Wednesday night.

A 4th paroxysm from the New SE crater just ended. It followed the previous one with only about 18 hours interval. It will be interesting to see how long Etna will keep up this busy pace.
