지구를 방문할수 있는 Alien이 있다면 그들은 우리가 상상조차 할수 없는
고도의 Technology를 장비한 존재가 틀림없을 것입니다. 만나지 안는게 좋지 안을가요?
우리는 그들에 비하면 이제 겨우 발을 떼기 시작한 Infant에 지나지 안을 겁니다.
그들은 지구인들을 잡어서 Fry 해 먹거나 저이들 위성에 데려가 노예로 쓰지 않을지??

Michio Kaku in the text agrees with you, WM.
Although Kaku is Japanese American, early on I came to like him
and his writings and have read all the books he has written for the public.
Obviously this new telescope will open up new universe to mankind
just like when I had my cataract surgeries for both eyes two years ago.
I feel that it should be the wish of mankind that seeing and learning of
the newly discovered universe and finding new unifying theory of the universe
may bring about lasting peace on planet Earth.

The James Webb Space Telescope (JWST or "Webb") is a joint NASA-ESA-CSA space telescope that is planned to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission.[6][7] The JWST will provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies.

James Webb Space Telescope insignia
The primary mirror of the JWST, the Optical Telescope Element, is composed of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6.5 metres (21 ft) diameter mirror—considerably larger than Hubble's 2.4 metres (7 ft 10 in) mirror. Unlike the Hubble telescope, which observes in the near ultraviolet, visible, and near infrared (0.1 to 1 μm) spectra, the JWST will observe in a lower frequency range, from long-wavelength visible light through mid-infrared (0.6 to 28.3 μm), which will allow it to observe high redshift objects that are too old and too distant for Hubble to observe.[8][9] The telescope must be kept very cold in order to observe in the infrared without interference, so it will be deployed in space near the Earth–Sun L2 Lagrange point, and a large sunshieldmade of silicon-coated and aluminium-coated Kapton will keep its mirror and instruments below 50 K (−223.2 °C; −369.7 °F).[10]
The JWST is being developed by NASA, the European Space Agencyand the Canadian Space Agency. The NASA Goddard Space Flight Center is managing the development effort following operations after launch by Space Telescope Science Institute [11]—and is named for James E. Webb, who was the administrator of NASA from 1961 to 1968 and played an integral role in the Apollo program.[12][13] The prime contractor is Northrop Grumman.[14]
Development began in 1996 for a launch that was initially planned for 2007 and a 500-million-dollar budget,[15] but the project has had numerous delays and cost overruns, and underwent a major redesign in 2005. The JWST's construction was completed in late 2016, after which its extensive testing phase began.[16][17] In March 2018, NASA further delayed the launch after the telescope's sunshield ripped during a practice deployment.[18] Launch was delayed again in June 2018 following recommendations from an independent review board.[19][20][21] Work on integration and testing of the telescope was suspended in March 2020 due to the COVID-19 pandemic,[22] adding further delays. Work has resumed, but NASA announced that the launch date has once again been delayed to October 2021.[3][23] The cost of developing the telescope is over $10 billion.
