    My first telescope experience was when I was 10. (1961). Our neighbor worked for the Lowell Observatory in Flagstaff, Arizona where we lived. He took us kids there to see the telescope. I got to look through the same telescope that Lowell himself used to make his famous observations of the planet Mars. That night Saturn was visible and I could clearly see its beautiful rings. Up to then I had only seen Saturn in a book. To see it with my own eyes through a telescope was an amazing experience for a ten year old kid! I was hooked on astronomy from that point forward. We looked at the Moon too. I was fascinated at the details clearly visible in the telescope but invisible to the naked eye. But Saturn was what I remember most. My childhood thrill was 'magnified' exponentially when I got to see the rings of Saturn close up during the Cassini mission. I followed that mission closely and thought often of how astronomy had grown and changed since I was a ten-year old boy looking at the rings through the Lowell telescope. Thrilling experiences both!

    :47 YES! When Halley's Comet last passed through. Out of curiosity I panned the sky for planets in our solar system. I will never forget seeing Saturn and its rings. Wow, it was the most beautiful thing I have ever seen. It was brilliant and glistened of angelic white light floating in space. Clearly the work of God's artwork.
    To date I have never seen anything like it. It was life changing. I witnessed it away from the Austin city lights at Reimer's Ranch swimming hole just due east of Milton Reimer Ranch Road starting at dusk. Spent the day at the hole, did some cave exploration, climbed to the top of Enchanted Rock finishing the day with my armature telescope. I could have spent a week there.

  • @justinesportsmedicine

    Not an Astronomer, Physicist, or Chemist but I have a question. Thank you Dr. Christian Ready and Dr. Fanson apologize for being tardy to this discussion. Dr. Ready I really appreciate the videos on JWST. But your question to Dr. Fanson and his answer was quite compelling on his decision to use a circular configuration and not the previously used hex shape due to blurring caused by the higher number of segments in the hex form.
    I understand that aluminum is frequently used because of its superior reflective properties I also looked up the melting requirement of "Al" and 1220 F is very hot but my question is would it not be more practical to use liquid "Al" layered on the mirror (direct or separated) to eliminate distortions and blurring I read that direct heating is not possible maybe liquefaction with strong acids or bases as this would eliminate the need for segmentation?

  • @leecowell8165
    @leecowell8165 11 месяцев назад

    How large is the primary mirror? 24.6 meters. Big a lot bigger than JWST. However ELT's is 39 meters (comprised of 798 individual segments). Its also currently being built in Atacama due to come online in 2028. Its currently about 50% complete and it too will have laser based atmospheric correction. Thus Magellan here is already obsolete compared to ELT. In fact there's a 30 meter scope attempting to be built in Hawaii (but its having difficulty due to native Indian protests that are ongoing). I cannot even imagine what these instruments are gonna discover regarding our universe.

    Totally unrelated to this video, but wanted to submit a request: Would you be interested in maybe doing a video about PSR J1719-1438b? I can’t find any online and I figured it’d be a great one to watch for others. Reading about it, it’s star (a millisecond pulsar) and how it came to be is so utterly fascinating (so extreme yet it also makes a lot of sense). Imagine: A “planet sized diamond”; or better: What would happen if you could *expose the core* of another star? 😳
    *EDIT:* I actually found _one_ video on this planet/pulsar, turns out it was uploaded by Swinburne University of Technology and features the astronomer who discovered it.

    I wonder and my question would be why telescopes are not build in polar regions? Lets say, Antarctica? It has most dry and thin layer of atmosphere and it rests in the dark half of a year? Also it has mountains high enough to be called really big.

    Someone should invent differential spectragraphic analysis to look for planets. Comppare the spectra of the star taken at several different periods of time to see if theres a planet pulling on the spectra. Might work with greater resolution than the radial velocity method for finding planets. I'd imagined that the GAIA data could be used in this way.

And unlike the Hubble, there is no way that it can be repaired, and it can't even be reached for a repair if it was possible! Besides, the ELT can do the job better and it's on the Earth!

    Didn't come for a conversation at a 6th grade level. Should be labeled appropriately,, age 9-13...

      Do the 9-13 year olds you know generally understand about diffraction limits, adaptive optics, spinning glass furnaces, and all the other details I could glean from this episode? Why don't you do graduate work in astronomy instead of looking for your information on YT if you don't like the level here?
