NASA celestial observation
information I will post interesting information from the NASA website I see every day. Featured celestial show of the month "Leonids meteor shower" "Orionids meteor shower" you waiting it. And it is the season of "taurids meteor shower group (South group · North group)" and "Comet C / 2017 O1"! １．"Leonids meteor shower" Appearance period: November 6 - November 30 Maximum day: November 18 For details see the following site... Leonids meteor shower ２．A few years ago, "Orionids meteor shower" where I was able to observe "big fireball" came! It is past the emergence maximum time, but it is around the time that the Taurids meteor shower immediately appears, I think that you can observe a meteor if you are watching Orion. Appearance period: October 2 - November 7 Maximum day: October 21 For details see the following site... Orionids meteor shower ３．"Taurid-meteor shower group (south group · northern group)" is also long term, there is a possibility of appearing until the end of November. "Taurid meteor shower group (South group)" Appearance period: September 25 - November 25 Maximum day: November 6 "aurid meteor shower group (North group)" Appearance period: September 25 - November 25 Maximum day: November 13 For details see the following site... The Taurid Swarm is Upon Us! ４．Although it is also introduced in the movie "NASA Jet Propulsion Laboratory; What's Up for November 2017", it is a time when the comet "Comet C / 2017 O1" is easy to observe. The "Comet C / 2017 O1" was also on NASA's "Astronomy Picture of the Day" on September 23 below. Astronomy Picture of the Day For details see the following site... What's Up for November 2017 NASA"HubbleSite" celestial observation information from:Tonight's Sky on HubbleSite. Tonight's Sky: November 2017 youtube;Tonight's Sky: November 2017 NASA's Hubble Space Telescope has been providing us with a number of astronomical new findings. NASA's "James Webb Space Telescope" which has already been almost completed ... We expect to wait for his launch. He does not orbit around the earth orbit like a space telescope or artificial satellite so far but is launched to a position far away than the moon so that the astronomical observation by the infrared sensor is not hindered, In order to avoid the sun's heat rays according to the revolution orbit about the sun, NASA maintain a calculated orbital trajectory to enter the shadow of the earth. To be sure, we heard that we always observe with the shadow of the Earth in the first design philosophy, but it seems that in moving images it orbits regularly on its orbit. He has not left yet, but please watch a video depicting his journey.

It became an unmanned lander of the European Space Agency that fulfilled the world's first comet landing on Turimov Gerasimenco comet. Rosetta Mission: Philae has Landed!

Note) Cycle 24: = 24 th solar activity cycle The sun is almost a 11-year cycle, activities are activated, and many black dots and flares are observed. In Japan, the National Astronomical Observatory, and many national laboratories are observing solar activity. According to "Japan Institute of Information and Communications Technology Electromagnetic Wave Measurement Institute Space Weather Informatics Laboratory" "Solar wind" Please click on "Solar wind" above, please have a look. Sun Emits 3 X-class Flares in 2 Days ↑ Two consecutive sun active flares were observed twice on June 10 and once on 11th, depending on the satellite and ground observation facility on NASA's two orbital orbit. Note) X-ray generation intensity by solar flare = X-ray grade Flux (unit: Watts per square meter = W / m 2) of X-rays (X-ray lines) with a wavelength of 100 - 800 picometers outside the atmosphere A 10−8 - 10−7 B 10−7 - 10−6 C 10−6 - 10−5 M 10−5 - 10−4 X > 10−4 X2 2 x 10−4 X3 3 x 10−4 As you know, electromagnetic waves of various wavelengths including radiation such as light, heat, X-rays and γ (gamma) radiation are radiated from the sun. When X3 class solar flare like this time occurs, high dose radiation is radiated from the sun, and in space it is exposed to a lethal dose of radiation. It is thought that it will not happen on the scale of the solar flare this time, but when high energy charged particles at the time of flare arrive at the earth, it will be transferred to the satellite / ground radio equipment and broadcasting equipment, electricity related facilities, There is a possibility that the equipment etc will be destroyed. In this situation, if high concentration of high energy charged particles arrive, trouble may occur in the GPS satellite and the car navigation system may become unusable. I was conducting research on "Reliability Engineering" at the laboratory, but because the "radio wave propagation or radio wave propagation" is the original specialty, the solar activity cycle causing a magnetic storm etc. is a familiar astrophysical phenomenon. It was renewed from the traditional diffusion model previously thought to a new diffusion model. "NASA's Goddard Space Flight Center" was uploaded on October 17, 2016 Please watch the video of youtube.
