Our Sun is located 24-26,000 light years from the center of the Milky Way. It circles the galaxy every 225-250,000 years, at a speed of 220 kilometers per second. The sun is a medium size star, a Yellow Dwarf, G type main sequence. It’s about one million times the size of planet Earth.

Core temperature:15,000,000 °C. Surface temperature: 5,500 °C.

The sun emits a steady stream of charged particles, the solar wind, at 450 km per second. It increases in strength during active periods, every 11 years or so. Active periods are marked by an increase in sunspots. Sunspots are Earth-sized regions where intense magnetic fields prevent hot gas from reaching the surface, driving temperatures down to around 4,000°C. They often correspond to active regions.

Where magnetic activity drives the formation of coronal loops, or prominences. Solar flares. And Solar tsunamis, technically “fast-mode magnetohydrodynamical waves.” In February 2009, the Stereo spacecraft detected one that rose to 100,000 km high, and raced outward at 250 kilometers per second. It was associated with an eruption of gas and magnetic fields called a coronal mass ejection.

A CME can blast a billion tons of matter out at 10 to 12 million kilometers per hour. A CME sends a pulse of solar plasma to the limits of the solar system, where it can impact planets or spacecraft. We see its arrival in spectacular aurora. They form when solar particles rain down on Earth’s atmosphere, causing oxygen and nitrogen atoms to glow.

NASA | EUNIS Sees Evidence

for Nanoflare Coronal Heating

Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun’s outer atmosphere so much hotter than its surface. The new observations show temperatures in the atmosphere so hot that only one current theory explains them: something called nanoflares – a constant peppering of impulsive bursts of heating, none of which can be individually detected – provide the mysterious extra heat.

These new observations come from just six minutes worth of data from one of NASA’s least expensive type of missions, a sounding rocket. The EUNIS mission, short for Extreme Ultraviolet Normal Incidence Spectrograph, launched on April 23, 2013, gathering a new snapshot of data every 1.3 seconds to track the properties of material over a wide range of temperatures in the complex solar atmosphere

The unique capabilities of EUNIS enabled researchers to obtain these results. The spectrograph was able to clearly and unambiguously distinguish the observations representing the extremely hot material – emission lines showing light with a wavelength of 592.6 Angstrom, where an Angstrom is the size of an atom – from a very nearby light wavelength of 592.2 Angstroms.

Steaua Nordului (Polaris B) a devenit de 4 ori mai stralucitoare ca in Anitchitate – North Star is 4x brighter than in antiquity

Steaua Nordului (Polaris) la centru (Photo wikipedia)

Timp de secole, Steaua Nordului a fost un important punct de reper pentru călători, atunci când încă nu exista busola. Strălucirea ei era constantă, însă acum acest aspect începe să se schimbe şi astronomii nu înţeleg de ce.

Steaua Nordului devine tot mai strălucitoare, iar acest fenomen s-a intensificat acum aproximativ 200 de ani, scrie Fox News. „Este ceva neaşteptat”, spune Scott Engle, de la Universitatea Villanova din Pennsylvania. El a observat comportamentul ciudat al acestei stele, numită popular Steaua Nordului, dar oficial Polaris B.

În secolul al XIX-lea, oamenii de ştiinţă au bănuit că Polaris face parte dintr-o categorie de stele care pulsează, iar acest lucru a fost confirmat ulterior. Ea este inclusă acum în categoria variabilelor Cepheide, dar, spre deosebire de alte stele din această categorie, Polaris fluctua foarte puţin, de aceea la început nimeni nu şi-a dat seama de asta.

În jurul anului 2000, Engle şi colegii săi au remarcat o schimbare dramatică în strălucirea acestui astru. Comparând mai multe observaţii mai vechi ale acestei stele, ei au înţeles că fluctuaţiile au început în urmă cu câteva sute de ani. În prezent, ea este de peste 4 ori mai luminoasă ca în Antichitate.

What is the North Star?

The reason Polaris is so important is because the axis of Earth is pointed almost directly at it. During the course of the night, Polaris does not rise or set, but remains in very nearly the same spot above the northern horizon year-round while the other stars circle around it. So at any hour of the night, at any time of the year you can readily find Polaris and it is always found in a due northerly direction. If you were at the North Pole, the North Star would be directly overhead.

The North Star has remained an eternal reassurance for northern travelers over the centuries. But recent and historical research reveals that the ever-constant star is actually changing.

After dimming for the last few decades, the North Star is beginning to shine brightly again. And over the last two centuries, the brightening has become rather dramatic.

„It was unexpected to find,” Scott Engle of Villanova University in Pennsylvania told SPACE.com. Engle investigated the fluctuations of the star over the course of several years, combing through historical records and even turning the gaze of the famed Hubble Space Telescope onto the star.

(In)constant as the North Star
Scientists have known since the early 20th century that the familiar star was part of a pulsating class known as Cepheid variables; its variations were suspected as early as the mid-1800s. But unlike most Cepheid variables, the pulses of Polaris are very small.

„If it had not been so popular as the North Star, we likely wouldn’t have known it was a Cepheid until modern times,” Engle said.

In the early 1990s, scientists realized that the oft-lauded brightness of Polaris was beginning to decline. Engle and his group began to research the star around the beginning of 2000, when they found that the dropping brightness was on the rise again.

„It started increasing rather rapidly,” Engle said.

Curious, the team began to search historical records to see what other measurements they could find. Combing through data from the past century, they compared the information on Polaris with observations of other celestial bodies from the same telescopes and details about the instruments to compare the relative brightness of Polaris over the years. They found that the star had grown brighter over the past hundred years.

The next step was to determine just how far back the increasing brightness went. Engle pursued observations by Danish astronomer Tycho Brahe in the 16th century and Persian astronomer Abd al-Rahaman al-Sufi in the 10th century, using information from historical texts to determine just how bright the star was in the ancient sky.

According to Engle, if we take the measurements of al Sufi and Ptolemy at face value, the North Star has brightened by about two and a half times over the last two centuries. Modern interpretations of the historical data indicate that it could be as much as 4.6 times brighter than it was in ancient times.

Too bright to handle
As they pursued the historical documents, Engle and his team continued to monitor the increasing brightness of Polaris. But they were stymied when a modern CCD device —essentially a very sensitive digital camera—replaced the older imaging device on their telescope. The newer technology was too sensitive to image the bright North Star.

The team relied on observations from amateur astronomer Richard Wasatonic, whose backyard telescope still utilized the less-sensitive imaging equipment. They also obtained observations from astronomers in Croatia and the Czech Republic who still utilized older equipment.

„We have to beg, borrow and steal to find people who use older photoelectric equipment,” Engle said, acknowledging the irony of wanting to use older equipment.

The team ran into similar difficulties when they sought to image Polaris with the Hubble Space Telescope. Even after receiving approval, he said that the HST team was very hesitant to let Engle and his colleagues image the bright star, concerned that the sensitive Cosmic Origins Spectrograph (COS) might suffer.

„They basically said, we know you’ve been approved, but you really have to convince us you aren’t going to damage our instrument,” Engle said.

The HST observations provided insights into the atmosphere of Polaris, which is changing along with its brightness.

Engle presented the results of his ongoing research in a poster session at the American Astronomical Society meeting in Washington, D.C., earlier this month.

Cometa Ison a supravietuit apropierea de soare – Comet Ison’s full swing around the sun – Coplesit de Creatia lui Dumnezeu

Photo credit http://earthsky.org Fa click pe poza sa o maresti.

Cometa ISON a supravieţuit trecerii sale pe lângă Soare, joi, şi a fost denumită „cometa zombie” de către astronomii americani, care consideră că acest corp ceresc neobişnuit „s-a întors dintre morţi”.

Trecerea cometei ISON pe lângă Soare s-a produs cu o viteză uluitoare, care a atins 1,4 milioane de kilometri pe oră. Concluziile iniţiale ale experţilor indicau faptul că ISON, un bulgăr uriaş de gheaţă şi praf stelar, venit de la marginea Sistemului Solar, nu a supravieţuit temperaturilor de câteva mii de grade Celsius în timpul apropierii de Soare şi că acest corp ceresc s-a dezintegrat.

Vineri, însă, spre surpriza specialiştilor, o pată strălucitoare şi-a făcut apariţia pe imaginile captate de sonda Soho, exact în locul în care era aşteptată traiectoria cometei ISON.

„Nu ştim deocamdată dacă este vorba de resturi rămase din cometă sau dacă o parte din nucleul cometei a supravieţuit”, afirmă NASA. Analizele preliminare sugerează faptul că cel puţin o parte din nucleul cometei ISON este intact. Deocamdată este prea devreme pentru ca astronomii să poată spune dacă ISON a rămas intactă sau a fost fragmentată şi să indice procentul din masa iniţială care a fost conservat, dar, în orice caz, masa rămasă este suficientă pentru a forma un nucleu cu o activitate vizibilă.

ENGLISH:

After several days of continued observations, scientists continue to work to determine and to understand the fate of Comet ISON: There’s no doubt that the comet shrank in size considerably as it rounded the sun and there’s no doubt that something made it out on the other side to shoot back into space. The question remains as to whether the bright spot seen moving away from the sun was simply debris, or whether a small nucleus of the original ball of ice was still there. Regardless, it is likely that it is now only dust.

Comet ISON, which began its journey from the Oort Cloud some 3 million years ago, made its closest approach to the sun on Nov. 28, 2013. The comet was visible in instruments on NASA’s Solar Terrestrial Relations Observatory, or STEREO, and the joint European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO, via images called coronagraphs. Coronagraphs block out the sun and a considerable distance around it, in order to better observe the dim structures in the sun’s atmosphere, the corona. As such, there was a period of several hours when the comet was obscured in these images, blocked from view along with the sun. During this period of time, NASA’s Solar Dynamics Observatory could not see the comet, leading many scientists to surmise that the comet had disintegrated completely. However, something did reappear in SOHO and STEREO coronagraphs some time later – though it was significantly less bright.
.
Whether that spot of light was merely a cloud of dust that once was a comet, or if it still had a nucleus – a small ball of its original, icy material – intact, is still unclear. It seems likely that as of Dec. 1, there was no nucleus left. By monitoring its changes in brightness over time, scientists can estimate whether there’s a nucleus or not, but our best chance at knowing for sure will be if the Hubble Space Telescope makes observations later in December 2013.
.
Regardless of its fate, Comet ISON did not disappoint researchers. Over the last year, observatories around the world and in space gathered one of the largest sets of comet observations of all time, which should provide fodder for study for years to come. The number of space-based, ground-based, and amateur observations were unprecedented, with twelve NASA space-based assets observing over the past year.

In awe of God’s creation – Joshua Tree National Park – California – Pomii Yucca din Parcul National – Coplesit de Creatia lui Dumnezeu

Joshua trees in Joshua National Park,  California.

Romaneste – Joshua Tree National Park – acest parc national din sud-estul statului California este declarat un parc national din 1994 cand Congresul SUA a declarat cei 3,199.59 km2   ca pamant/desert protejat. Parcul este numit pentru padurile cu pomii bastinasi Joshua (Yucca brevifolia) care acopera cei peste 3 mii de km patrati. Aces pamant este putin mai mare decat statul din estul Americii- Rhode Island. Parcul include doua deserte- cel elevat, Deserul Mojave si cel plat, Desertul Colorado. Muntii mici San Bernardino fac parte din sut-westul Parcului.

Joshua Tree National Park is located in southeastern California. Declared a U.S. National Park in 1994 when the U.S. Congress passed the California Desert Protection Act (Public Law 103-433), it had previously been a U.S. National Monument since 1936. It is named for the Joshua tree (Yucca brevifolia) forests native to the park. It covers a land area of 790,636 acres (1,235.37 sq mi; 3,199.59 km2)– an area slightly larger than the state of Rhode Island. A large part of the park, some 429,690 acres (173,890 ha), is a designated wilderness area. Straddling the San Bernardino County/Riverside County border, the park includes parts of two deserts, each an ecosystem whose characteristics are determined primarily by elevation: the higher Mojave Desert and lower Colorado Desert. The Little San Bernardino Mountains run through the southwest edge of the park.

Romanian – Pomii Joshua ( Yucca brevifolia), pentru care este numit acest parc national, se gasesc in Desertul elevat Mojave. Pomii se afla si in paduri si singuri la distanta unii de altii.

The higher and slightly cooler Mojave Desert is the special habitat of Yucca brevifolia, the Joshua tree for which the park is named. It occurs in patterns from dense forests to distantly spaced specimens.


The Joshua tree, Yucca brevifolia, is a member of the Agave family. (Until recently, it was considered a giant member of the Lily family, but DNA studies led to the division of that formerly huge family into 40 distinct plant families.) Like the California fan palm, Washingtonia filifera, the Joshua tree is a monocot, in the subgroup of flowering plants that also includes grasses and orchids. Don’t confuse the Joshua tree with the Mojave yucca, Yucca schidigera. This close relative can be distinguished by its longer, wider leaves and fibrous threads curling along leaf margins. Both types of yuccas can be seen growing together in the park. The Joshua tree provides a good indicator that you are in the Mojave Desert, but you may also find it growing next to a saguaro cactus in the Sonoran Desert in western Arizona or mixed with pines in the San Bernardino Mountains.

In awe of God’s creation – Danielson Crater on planet Mars

Mars is the fourth planet from the Sun in the Solar System. Named after the Roman god of war, Mars, it is often described as the „Red Planet” as the iron oxide prevalent on its surface gives it a reddish appearance.Mars is a terrestrial planet with a thinatmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, andpolar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature.

Until the first successful flyby of Mars occurred in 1965, by Mariner 4, many speculated about the presence of liquid water on the planet’s surface. This was based on observed periodic variations in light and dark patches, particularly in the polar latitudes, which appeared to be seas and continents; long, dark striations were interpreted by some as irrigation channels for liquid water. These straight line features were later explained as optical illusions, though geological evidence gathered by unmanned missions suggest that Mars once had large-scale water coverage on its surface.[16] In 2005, radar data revealed the presence of large quantities of water ice at the poles, and at mid-latitudes.The Mars rover Spirit sampled chemical compounds containing water molecules in March 2007. The Phoenix lander directly sampled water ice in shallow Martian soil on July 31, 2008. You can read more fascinating facts about the planet Mars here- http://en.wikipedia.org/wiki/Mars

via All That is Interesting

The geographic features of other planets are often captivating and enigmatic, and Mars’ Danielson crater is no exception to the rule. According to NASA, its wave-like layering is the result of periodic changes in climate related to changes in tilt of the planet.
