Beautiful astronomical photo last week by NASA

The nebula of Abell 39 looks at first glance like a ghost. It is 5 light-years wide and fits within the Milky Way and is 7000 light-years away from the constellation Hercules. Abell 39 is a planetary nebula formed after a Sun-sized star exploded thousands of years ago, while leaving it at the center of a white dwarf star. Its simple circular structure is a good clue for astronomers to understand the chemical composition and life cycle of stars. The sky behind the galaxy can see clearly through this fuzzy nebula.

The Simeis Ruins 147 of this supernova explosion is 3,000 light-years away, 150 light-years wide and spread by 6 full moons in the sky. On the left is the Elnath star of the constellation Taurus. The red color is raised to show the radiation of hydrogen gas. The explosion occurred about 50,000 years ago and left not only this cloud but also a neutron star or a pulsar in the center.

According to Greek Mythology, Atlas deities supports the sky on his shoulders, but in this picture, Nauset lighthouse lamp at Cape Cod, Masachusettes, America does that. Grafting from 30 1-minute exposure photos, these bright streaks of the northern star sky clearly indicate the rotation of the Earth around the axis with the North Pole being hidden behind the lighthouse light. Every day the star sky turns 360 degrees, ie 15 degrees per hour.

Looking from the Suomi-NPP satellite, we can easily recognize the North American continent at night with light from major cities like Chicago, Toronto, Montreal, Quebec, NewYork, Boston, Philadelphia . Part The top of the main image is the north aurora that surrounds the polar region and extends into lower latitudes, caused by geomagnetic storms, caused by the intense emission of the Sun at the beginning of the month. The curtain of light at a height of more than 100km, is created by electrically charged particles accelerated in the magnetosphere that stimulates the molecules of oxygen and nitrogen on the upper atmosphere.

This airspace of the constellation Archer spreads 3 degrees, ie 6 times the full moon in the sky. Below is the Nebula M8, on the right is the M20 nebula and the lower left is NGC 6559, located amidst numerous stars in the center of the Milky Way. Red is from dust reflecting light and blue is in fact red due to hydrogen-emitting nebulae. The 1.4 gigapixel sensor has been used to scan the sky, searching for meteors and comets that are at risk of colliding with the Earth and studying the sky.

The wide, cloudy clouds in this Scorpio are reflecting light from sparkling stars. This is the MBM 54 nebula, made up of molecular clouds, about 1,000 light-years away. The spiral galaxy NGC 7497 is 60 million light-years away, far behind the cloud in the center of the image.
