IC 1396: Emission Nebula in Cepheus

Stunning emission nebula IC 1396 mixes glowing cosmic gas and dark dust clouds in the high and far off constellation of Cepheus. Energized by the bright central star seen here, this star forming region sprawls across hundreds of light-years, spanning over three degrees on the sky while nearly 3,000 light-years from planet Earth. Among the intriguing dark shapes within IC 1396, the winding Elephant's Trunk nebula lies just below center. Stars could still be forming inside the dark shapes by gravitational collapse. But as the denser clouds are eroded away by powerful stellar winds and radiation, any forming stars will ultimately be cutoff from the reservoir of star stuff. The gorgeous color view is a composition of image data from narrowband filters, mapping emission from the nebula's atomic oxygen, hydrogen, and sulfur into blue, green, and red hues.

Tem quem goste de seios grandes, mas a grande maioria se sente constrangida com osseios grandes demais. Nem sempre é possível fazer uma plástica, pois a condição financeira não ajuda.

Biologists believe that whales (and modern hoofed animals) evolved from a group of extinct land mammals called mesonychid condylarths. The mesonychids resembled a slim wart hog without the tusks and hoofs.

This country (the Roman Empire) has more than four hundred smaller cities and towns. It extends several thousand li in all directions. The king has his capital (that is, the city of Rome) close to the mouth of a river (the Tiber). The outer walls of the city are made of stone.

…The ruler of this country is not permanent. When disasters result from unusual phenomena, they unceremoniously replace him, installing a virtuous man as king, and release the old king, who does not dare show resentment.

The common people are tall and virtuous like the Chinese, but wear hu (‘Western’) clothes. They say they originally came from China, but left it.

They have always wanted to communicate with China but, Anxi (Parthia), jealous of their profits, would not allow them to pass (through to China).

- from the the Weilüe, an account from the 200s CE of the interactions between the Romans and the Chinese. It was written by Yu Huan, a state historian for Cao Wei during the Three Kingdoms Period.

July 14 Solar Flare and a Coronal Mass Ejection

A medium-sized (M2) solar flare and a coronal mass ejection erupted from the same, large active region of the sun on July 14, 2017. The flare lasted almost two hours, quite a long duration. The coils arcing over this active region are particles spiraling along magnetic field lines.
