Saturns North Pole Hexagon.

Jupiter’s North Pole Unlike Anything Encountered in Solar System

NASA’s Juno spacecraft has sent back the first-ever images of Jupiter’s north pole, taken during the spacecraft’s first flyby of the planet with its instruments switched on. The images show storm systems and weather activity unlike anything previously seen on any of our solar system’s gas-giant planets.  “First glimpse of Jupiter’s north pole, and it looks like nothing we have seen or imagined before,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “It’s bluer in color up there than other parts of the planet, and there are a lot of storms. There is no sign of the latitudinal bands or zone and belts that we are used to – this image is hardly recognizable as Jupiter. We’re seeing signs that the clouds have shadows, possibly indicating that the clouds are at a higher altitude than other features.”

Annular Solar Eclipse over New Mexico 

What is this person doing? In 2012 an annular eclipse of the Sun was visible over a narrow path that crossed the northern Pacific Ocean and several western US states. In an annular solar eclipse, the Moon is too far from the Earth to block out the entire Sun, leaving the Sun peeking out over the Moon’s disk in a ring of fire. To capture this unusual solar event, an industrious photographer drove from Arizona to New Mexico to find just the right vista. After setting up and just as the eclipsed Sun was setting over a ridge about 0.5 kilometers away, a person unknowingly walked right into the shot. Although grateful for the unexpected human element, the photographer never learned the identity of the silhouetted interloper. It appears likely, though, that the person is holding a circular device that would enable them to get their own view of the eclipse. The shot was taken at sunset on 2012 May 20 at 7:36 pm local time from a park near Albuquerque, New Mexico, USA. Tomorrow another annular solar eclipse will become visible, this time along a path crossing Africa and Madagascar.

Messier 1 - The Crab Nebula

Potentially Humanity’s First Historically Observed Supernova

The Crab Nebula is the first astronomical object identified with a historical supernova explosion. Around in the year 1054, Chinese astronomers identified a large bright object that suddenly and mysteriously appeared in the sky. The explosion was so bright that it was even visible during the day time.

700 years later the super nova remnant faded in brightness as it expanded and was nearly forgotten. The Super Nova Remnant was rediscovered in 1758 ( officially re-recorded) by Charles Messier while he was creating a catalog of mysterious objects that looked like comets but were not.

We now know that the beautiful Crab Nebula is the magnificent result of the death of a star, which was unknown to Charles Messier and the Chinese Astronomers that discovered the Object. Now, thanks to space telescopes such as Hubble and Chandra, we can image the Nebula in great detail. The bottom left image is of a small region of the Crab Nebula. It shows “Rayleigh–Taylor instabilities in its intricate filamentary structure” and gives scientists a better understanding of the death of stars. The image to the bottom left shows combined visible light data from Hubble and x-ray data from Chandra.
