Solar Eclipse Of April 29, 1976
An annular solar eclipse occurred at the Moon's descending node of the orbit on Thursday, April 29, 1976. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible from North Africa, Greece, Turkey, Middle East, central Asia, India, China. 5 of the 14 eight-thousanders in Pakistan and China—Nanga Parbat, K2, Broad Peak, Gasherbrum II and Gasherbrum I, lie in the path of annularity. Observation The Institute of Physics and Institute of Mathematics of the Chinese Academy of Sciences and the Xinjiang Earthquake Team conducted observations of gravitational effects using gravimeters, inclino ...

Solar Eclipse
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, totally or partially. Such an alignment occurs during an eclipse season, approximately every six months, during the new moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the Moon ...

Gasherbrum I
Gasherbrum I ( ur, ; ), surveyed as K5 and also known as Hidden Peak, is the 11th highest mountain in the world at above sea level. It is located in Shigar District in the Gilgit–Baltistan region of Pakistan. Gasherbrum I is part of the Gasherbrum Massif, located in the Karakoram region of the Himalaya. Gasherbrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gasherbrum IV; but in fact, it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain." Gasherbrum I was designated K5 (meaning the 5th peak of the Karakoram) by T.G. Montgomerie in 1856 when he first spotted the peaks of the Karakoram from more than 200 km away during the Great Trigonometric Survey of India. In 1892, William Martin Conway provided the alternate name, Hidden Peak, in reference to its extreme remoteness. Gasherbrum I was first climbed on July 5, 1958, by Pete Schoening and And ...

November 1976 Lunar Eclipse
A penumbral lunar eclipse took place on Saturday, November 6, 1976, the second of two lunar eclipses in 1976, the first being on May 13. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 83.827% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 4 hours, 25 minutes and 52.1 seconds. Occurring only 0.3 days after apogee (Apogee on Saturday, November 6, 1976), the Moon's apparent diameter was 6.5% smaller than average. Saros series This is the 9th member of Lunar Saros 145. The previous event was the October 1958 lunar eclipse. The next event is the November 1994 lunar eclipse. Solar Saros 152 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Solar Eclipse Of October 23, 1976
A total solar eclipse occurred at the Moon's ascending node of the orbit on Saturday, October 23, 1976. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. This total solar eclipse began at sunrise in Tanzania near the border with Burundi, with the path of totality passing just north of the large Tanzanian city of Dar es Salaam. It then crossed the Indian Ocean, passing St. Pierre Island, Providence Atoll and Farquhar Atoll of Seychelles before making landfall in southeastern Australia. The largest city that saw totality was Melbourne. After leaving the Australian mainland, the path of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
May 1976 Lunar Eclipse
A partial lunar eclipse took place on Thursday, May 13, 1976, the first of two lunar eclipses in 1976, the second being a penumbral lunar eclipse on November 6, 1976. At maximum eclipse, a small bite out of the Moon should have been visible. The eclipse lasted for 1 hour, 15 minutes and 23.8 seconds, with just 12.17% of the Moon in shadow at maximum. Occurring only 1.1 days after perigee (Perigee on Wednesday, May 12, 1976), the Moon's apparent diameter 5.4% larger than average. Eclipse season This is the second eclipse this season.

Gravitational Acceleration
In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag). This is the steady gain in speed caused exclusively by the force of gravitational attraction. All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the bodies; the measurement and analysis of these rates is known as gravimetry. At a fixed point on the surface, the magnitude of Earth's gravity results from combined effect of gravitation and the centrifugal force from Earth's rotation. At different points on Earth's surface, the free fall acceleration ranges from , depending on altitude, latitude, and longitude. A conventional standard value is defined exactly as . Locations of significant variation from this value are known as gravity anomalies. This does not take into account other effects, such as buoyancy or drag. Relation to the Universal Law Newton's law of universal gravitation states that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karakoram Pass
The Karakoram Pass () is a mountain pass between India and China in the Karakoram Range. It is the highest pass on the ancient caravan route between Leh in Ladakh and Yarkand in the Tarim Basin. 'Karakoram' literally means 'Black Gravel' in Mongolic. Historically, the high altitude of the pass and the lack of fodder were responsible for the deaths of countless pack animals while the route was notorious for the trail of bones strewn along the way. There is an almost total absence of vegetation on the approaches to the pass. Travelling south from the pass involved three days' march across the barren Depsang Plains at about . To the north, the country was somewhat less desolate and involved travellers crossing the relatively easy and lower Suget Dawan (or Suget Pass) before reaching the lush grazing grounds around Shahidullah or Xaidulla in the upper valley of the Karakash River. The pass is in a saddle between two mountains and about wide. There is no vegetation or icecap a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xinjiang
Xinjiang, SASM/GNC: ''Xinjang''; zh, c=, p=Xīnjiāng; formerly romanized as Sinkiang (, ), officially the Xinjiang Uygur Autonomous Region (XUAR), is an autonomous region of the People's Republic of China (PRC), located in the northwest of the country at the crossroads of Central Asia and East Asia.
