A few weeks after making Sun's nearest Sun, Nasa's Parker Solar Probe sends its data back.

After inclusion in the observations, there is an extremely active image of the active gas, or the plasma that flows out of the star.

In fact, the bright dot in Jupiter is far away. The black dots are simple repeats because of the way the photo has been built.

The WISPR Parker tool won the 27.2 million kilometer view of the surface of the Sun on November 8.

The identifier looked out side behind the thick crew heat shield.

Artwork: Parker must always keep his heat wire in touch with the Sun

Nasa's mission was launched back in August to study the mysteries of the external atmosphere of the Sun, or corona.

This region is extremely hot than the "face" of the star, or photo drawings. Although this can be 6,000 degrees, the external atmosphere can reach a temperature of just a million degrees.

Mechanisms that produce this heating are not fully understood.

Parker aims to solve the puzzle by passing the external atmosphere and sampling its particle, magnetic and electric particles directly.

"We need to go into this region in order to sample the new plasma, the new material, to see what processes, which physics is there," explained Nicola Fox , director of the Heliofysics Division at Nasa Headquarters in Washington DC.

"We want to understand why this temperature collision is, as it is – you walk away from a hot star and the atmosphere is tighter or cooler as you would you and her expect. "

Parker cutting records are not just about being close to the Sun, it also sets new speed records for a spacecraft. On the recent flight, he managed to achieve 375,000km / h. The quicker was any previous inspector managed around 250,000km / h.

Parker will go faster again on the Sun's legs in the future.

The latest science of the mission appears here at the Fall Fall Meeting of the American Geophysical Union – the largest annual collection of Earth scientists and space.
