Whenever tingling by rubbing my hand with the alcohol for disinfection under COVID19, and it recalls a warm mother and the plaster of the blue-black color even on a cold snowy night.

Now, it is November, also the ten days moon is approaching to the full moon, the sky is filled with moon light. In this, when I took an enhanced shot near Andromeda at the zenith against the moonlight, the pale round figure of the planetary nebula Blue Snowball (NGC 7662) emerged. Even if it looks small, the diameter is about 50,000 astronomical units (au,0.8 light-years). It is understandable that it was named Blue Snowball because this color is pale, but in fact the temperature is 75,000K, and the known It is a nebula with the highest temperature among stars.

Really everyone played in the snow well as mischievous baby. Once the snowballs of the snowballs of the snowballs melted and hardened like zarame, it was hardened and good to throw. The color became a little bluish, heavy, and it was easy to throw when water was included. It caused our limbs were itchy sorely with chilblains and chap, while we were playing, but we were forgot it. But gradually irked when we came home and warmed up.

Suddenly it hurts and hot. Bake the trowel with bright red charcoal in a brazier, pushed it to the blue-black plaster to soften, and my mother caulked it to the crack of limb. Strangely enough, this blue-black plaster was caulked, but unlike tattoos, there were no marks left. This plaster was expensive in our house, and my mother endured it without using much, even if her sardines were terrible.

Teacher N of social studies held the chalk diagonally so that it hung on the surface of the blackboard, pushed it from the right to the bottom left at a dash, and drew the dotted line immediately. "I surveyed later, she was surely a spy," I felt his words was covered his confession. About25 years after the defeat, Teacher N, who had been demobilized from the Chinese front, spoken about the tragic event that he had caused from behind a lady who had been doing laundry by the river.

Now that the half century has passed, as autumn deepens, Cassiopeia is showing its W shape at the center of tug-of-war tensions from the North Star and zenith. When to have been photographing h Persei of the Double Cluster on this line for about 100 seconds, it happened to have a satellite from west to east without incident, and a little trace of light was memorized by SONY's CMOS and left. It means this 100 second picture was coincidentally able to memorize two different dimensions of time, one is milli second incident and another is a scattered cluster of stars with a radius of about 14 million years since birth, a radius of 75 light years, and a distance of 7,500 light-years from the earth.

A bat man turned around and grinned, so for I cut his neck with the sword, but it was not bloody, and I woke up to see his red tongue and laugh.

In November, the moon became thinner, and it begins to see the club of the giant Orion. It is also quite luxurious to feel the season from autumn to winter from the starry sky.

This is enhanced view photo of Bow Tie Nebula NGC 40 (Caldwell 2) of Cascius between Cassiopeia and Dragon of the northern horizon.

Although it is the end of a star, the ambient gas temperature is 10,000 ℃, the diameter is about one light-year, and the huge and beautiful far ultraviolet halo showed. Bow Tie naming is not this nebula, it's a kind of category, but it doesn't seem like someone has given a bright name. Probably it was felt more frightening than beauty, I was also dominated by the nightmare.

Well, it is said that this new virus started with bats. Not only bats but also migratory birds are said to be reservoirs of the virus. It has been pointed out that bats are mammalian species and enormous number and kind, wide distribution and genetic traits etc.

Indeed, their live circumstance is an incubator-like environment with stable temperature and humidity in a dark cave, it has effectiveness. However, and additionally, it might be considered that aerosols containing of bat exhalation is evenly dispersed by ultrasonic power from their own body.

Airex uses ultrasonic energy for hydrogen peroxide decontamination. This is the world's first system and trade name is UltraDecon^®(world brand X'SONA^™)that aerosolizes hydrogen peroxide at room temperature and evaporates and diffuses under ultrasonic reflection fields.

Heating and air agitation as in the conventional flash evaporation method are not used, and stable decontamination can be performed in a small amount of hydrogen peroxide in a short time. It has already been applied to aseptic filling lines, aseptic tests, regenerative medicine product manufacturing processes, and incubators (GMP incubators^®).

But this ultrasonic decontamination UltraDecon^® may be a technology that has been surpassed by bat.

However, any virus will greet catastrophes with their own mutations. Certainly, and indeed, it is same that human should be self-disciplined. But when we look at it this way, this nebula shining at the end of the reincarnation of the stars, even it’s named as the bat man with a bow tie, it looks not frightening but lovely one.
