Magnetic fields and supergranule velocity fields on the quiet sun I have carried out detailed study on the quiet sun magnetic fields and super-granule velocity fields. This thesis consists of 6 themes. 1.I studied the statistical properties of quiet sun magnetic fields, including size distribution, evolution, flux budget of magnetic flux elements, and the magnetic diffusion constant.From the observations, I derived that the magnetic diffusion constant is ±150 km[superscript 2]/sec in the quiet region.I found that cancelling features and Ephemeral Regions are major sources of magnetic flux disappearance and replenishment. 2.rom the observations, I derived that the magnetic diffusion constant is ±150 km[superscript 2]/sec in the quiet region.

Astronomy for Kids Sunspots Sunspots are dark areas that appear on the surface of the Sun. They are caused by strong magnetic activity within the Sun. Sunspots are not permanent and they can move slowly across the surface of Sun changing size as they move. The appearance of sunspots follows the solar cycle of eleven years. Every eleven years there will be a period of increased sunspot activity.

The Starry Night The artist wrote of his experience to his brother Theo: This morning I saw the country from my window a long time before sunrise, with nothing but the morning star, which looked very big.. This morning star, or Venus, may be the large white star just left of center in The Starry Night. The hamlet, on the other hand, is invented, and the church spire evokes van Gogh's native land, the Netherlands. The painting, like its daytime companion, The Olive Trees, is rooted in imagination and memory.

- Neptune's Great Dark Spot: Gone But Not Forgotten Credit: Voyager Project, JPL, and NASA Explanation: When NASA's Voyager 2 spacecraft flew by distant Neptune in August of 1989, astronomers were shocked. Since Neptune receives only 3 percent the sunlight Jupiter does, they expected to find a dormant, dark, frigid planet. Instead, the Voyager images revealed evidence of a dynamic and turbulent world. One of the most spectacular discoveries was of the Great Dark Spot, shown here in close-up. Surprisingly, it was comparable in size and at the same relative southern latitude as Jupiter's Great Red Spot, appearing to be a similar rotating storm system. Winds near the spot were measured up to 1500 miles per hour, the strongest recorded on any planet.

Sun The Sun, the star at the center of our solar system, is an average-sized, middle-aged star. It is a gas ball made mostly of hydrogen and helium, with a small amount of carbon, nitrogen, oxygen, and trace amounts of heavy metals. The Sun is roughly 865,000 miles (1,392,000 kilometers) in diameter, about 109 times the diameter of Earth.

The life of Aldebaran The main Characteristics of Aldebaran. The main distinction of Aldebaran is that it is located in the Taurus constellation as the eye of Taurus. Aldebaran gets its name from Arabic as the follower which describes the way in which Aldebaran rises after the Pleiades.he life of Aldebaran. Before Aldebaran was anything it started off as a large/ relatively cool mass of gas, part of a nebula. As gravity causes the gas to contract, its temperature rises, eventually becoming high enough to trigger a nuclear reaction in its atoms.

- WHAT IS THE SEA OF TRANQUILITY? The Sea of Tranquility is a dark spot located in the northern hemisphere of the Moon. The sea is not a body of water but a lower-altitude plain. As a result of earlier periods of lunar volcanism, it is filled with dark, solidified lava. Cite this article. Pick a style below, and copy the text for your bibliography.

Deepsky Top-100 (11): Y cnv (La Superba) Deepsky Top-100 (11): Y cnv (La Superba). In Canes Venatici, the hunting dogs, you can find a beautiful red star, Y Canum Venaticorum, or La Superba. Y CVn is a carbon star. Most of these class C stars are evolved cooling giants with a large abundance of carbon dust in their outer shells.ccording to James Kaler, Y CVn is one of the coolest naked eye stars, with a temperature of 2200 Kelvin. If you cannot detect using your naked eyes, don't worry. La Superba is easy to locate. Start at 12 Alpha Canum Venaticorum, also knows as Cor Caroli, a double star of magnitude 2.89.

Earthâs Sun: Facts About the Sunâs Age, Size and History The photosphere is the lowest layer of the sun's atmosphere, and emits the light we see. It is about 300 miles (500 km) thick, although most of the light comes from its lowest third. Temperatures in the photosphere range from 11,000 F (6,125 C) at bottom to 7,460 F (4,125 C) at top.he solar atmosphere above that consists of the photosphere, chromosphere, a transition region and the corona. Beyond that is the solar wind, an outflow of gas from the corona. The core extends from the sun's center to about a quarter of the way to its surface.

The abiotic factors that influence life forms vary with location within ocean systems. Oceanographers divide the ocean into five broad vertical zones as seen in the chart above. Compare the characteristics of the five zones. Where would you expect to find the kelp forest, a type of algae, pictured here and why? A) Algae live in the top two zones in the ocean because light penetrates both zones. B) Algae can live in the three top zones. The abyss is too dark for the algae to survive. C) Algae live only in the epipelagic zone because it is the only zone with enough light for photosynthesis. D) Algae live throughout the five oceans zones because they are the producers that are the base of all food webs.

What Are Some Special Features of Uranus? Special features of Uranus include its 27 moons, faint rings and construction, which is mostly ice. Uranus consists of water, methane and ammonia above a small, rocky inner core. Methane gas gives Uranus its blue tint. Uranus, along with Venus, rotates in the direction opposite to that of most other planets.

The Rise of Industrial America, 1877-1900 The railroads powered the industrial economy. They consumed the majority of iron and steel produced in the United States before 1890. As late as 1882, steel rails accounted for 90 percent of the steel production in the United States. They were the nation’s largest consumer of lumber and a major consumer of coal.

The Sun Profile The surface of the Sun, called the photosphere, is at a temperature of about 5800 K. Sunspots are cool regions, only 3800 K (they look dark only by comparison with the surrounding regions). Sunspots can be very large, as much as 50,000 km in diameter.

What Are Sunspots? Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them. Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun's magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption.

The Sun Profile But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun. The Sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol.

Son of Poseidon Features of Triton. Triton is the coldest known object in the Solar System. Its surface temperature averages only -391° F (-235° C). This is caused by the moon's high albedo. Very little sunlight is absorbed by the surface. Triton's axis of rotation is tilted 157 degrees with respect to Neptune's axis.
