Happy 25th Birthday, Hubble Telescope!

by Melannie Svoboda SND on April 27, 2015

On April 24, 1990 the Hubble Telescope was launched into orbit by NASA aboard the space shuttle Discovery. Named after Edwin Hubble (a renowned American astronomer), this amazing telescope has transformed what we know about outer space. Since it began orbiting the earth, it has continuously sent back pictures of our universe that can only be described as awesome!

First a few facts. The Hubble Telescope is over 43 feet (13 m.) long, about the size of a large school bus. It weighs 24,500 pounds (11,110 kg.) or the weight of two full-grown elephants. Hubble is able to take such clear pictures because it orbits at an altitude of 343 miles which is beyond our atmosphere. Hubble is fast too, speeding along at 17,500 miles per hour. This means it orbits the earth every 97 minutes.

Hubble is powered by the sun using two 25 foot solar panels. It operates 24 hours a day, 7 days a week. Each week Hubble transmits 120 gigabytes of scientific data back to earth. That’s equivalent to 3,600 feet of books on a very long library shelf! When Hubble was first launched, its creators were dismayed to learn that its main mirror was defective. Hence, the images it was sending back were blurred. This problem was corrected in 1993 when astronauts from the space shuttle Endeavor successfully performed a service mission to the telescope. Since then four subsequent space shuttle missions have repaired or upgraded the telescope.

Hubble is not cheap. It cost 1.5 billion dollars to build and launch. The cost to maintain Hubble is 100 times greater than ground-based telescopes. But Hubble is in continuous use. Strictly speaking, anyone can apply for time to use Hubble, but most users are from the scientific community. Thousands of proposals to use Hubble are received each year from all over the world. A special board decides who gets to use the telescope. Only about 1/5th of the requests are able to be granted each year.

What has Hubble accomplished? It has helped us determine more accurately the age of the universe (between 13 and 14 billion years old.) It has also identified quasars and the existence of so-called black energy.  It has informed us that the universe is expanding faster than previously thought. It is bigger than we thought too. There are at least 50 billion other galaxies, each one containing between ten million and 1 trillion stars! Within our own galaxy, Hubble has confirmed the existence of exoplanets, or planets outside our solar system. And it has allowed us to see deeper into space and farther back in time than ever before. And in doing all of this, Hubble has beamed back to earth those magnificent pictures of our universe which (as someone remarked), “has united our planet in wonder.”

Hubble is expected to continue functioning until 2020. Meanwhile its successor, the James Webb Space Telescope, is

scheduled to be launched in 2018. This infrared telescope will be able to look even farther into space and time than Hubble.

For me personally, I am happy to be living at the time when we have access to this marvelous invention. I thank God for the Hubble Telescope and all the information and knowledge it is giving us. When I gaze at some of its pictures and scan some of its data, I find myself asking, “What must God be like?” Or “If this created universe is so vast and so spectacular, what must the Creator be like?” The Hubble Telescope has made me (and probably many others) realize that God is “bigger,” more incredible, more mysterious, more wondrous, more astounding, more amazing, more awe-inspiring than we ever knew or thought or could imagine.

I would like to conclude this reflection with a few more images taken by Hubble. But first, the song I have selected is “How Great Thou Art.” After you listen to the song (and perhaps sing and pray along with it), let me know your thoughts on Hubble, the images from Hubble, or the song. Thank you!

Here are a few more images from Hubble:

Dios mío, me espanta tu grandeza al ver tu creación del cosmos! Y me siento tan pequeño como un grano de arena en el espacio tiempo! Gracias Padre Yahve por amarnos así,, por habernos enviado a tu hijo Jesus el Cristo y por darnos al Espíritu Santo, gracias infinitas por tu gran amor al hombre y por tu creación.

Dear Readers,

On May 1 I will be giving a day for hospital chaplains, nurses, and care-givers at Holy Spirit Hospital in Camp Hill, PA. Once again I ask for your prayers for this day. Thank you very much! Sr. Melannie

What beautiful images from the Hubble telescope! They remind how vast the universe is and how big is our Creator. I sometimes keep God in a very small box.

Thanks for the reflection Sr. Melanie.

Dear Kathleen, I agree. Sometimes we make God too small….maybe so we can “manage him”…Thanks again for writing! Sr. Melannie

Awe inspiring! The words, the pictures and the music are beautifully put together. Thank you so much for your postings! I look forward to every Monday!
I was taught by the Sisters of Notre Dame in high school in Providence, RI, and am so happy to still have this connection with them.
Thank you again.

For me, the Hubble Telescope will always be a lesson in perseverance. It received much critical press when it was found to be flawed, but thank goodness the US government and scientific community had the fortitude to keep at it and commit the funding to fix it. It reminds me that in every endeavor, many things may go wrong and (even after huge expense), problems will show up. I congratulate the people who press on despite the nay-sayers and see it through. And I am thankful that our heavenly Father continues to invest in ME, despite all my flaws.

Thank you, Karen, for your take on this: the lesson in perseverance. And I like how you applied it to God, THE great “perseverer.” Sr. Melannie

I’ve always been a strong supporter of space travel and our ability to see beyond our own planet into more of God’s awesome universe. However, last night on 60 Minutes, they spoke about different countries sending various “instruments” into space. One has already smashed into something floating around up there and sent thousands of pieces into orbit. They also spoke about other countries wanting to shoot down U.S. satellites so we can’t “spy” on others. It was very disheartening that something so good and beautiful can be misused for not-so-good endeavors. Let us hold it all before our Good God in prayer so that we can continue to see the awesome kind of images Sr. Melannie showed us.

Dear Sr. Janet, I didn’t see the “60 Minutes” show, but thank you for bringing it to my (our) attention. Yes, we have so much to pray for. Your words are a good reminder for all of us. Thank you! Sr. Melannie

Hearing/singing How Great Thou Art always brings tears to my ears. We can be so focused on our small little lives that we forget the magnitude and magnificence of God’s creation.

Melannie Svoboda SND April 29, 2015 at 9:51 am

Yes, Cathy, the magnificence of God’s creation is something we need to contemplate regularly. It helps to put other things in perspective. Thank you for your response! Sr. Melannie

I was starting to “understand” from the beautiful world we live in, and the immense love of Jesus to redeem us, how great God is…but when I try to ponder that there are 50 billion galaxies out there, and how unfathomable and awesome God must be, I am humbled and struck with love and wonder.

Dear Diane, Yes the beauty and immensity of the universe certainly humbles us and fills us with love and wonder. Thank you for expressing this so well! Sr. Melannie

Shared this blog with my son who is an engineer with NASA in Virginia and an avid amateur astronomer. He enjoyed it and commented that your blog name reminded him of M63, aka. “The Sunflower Galaxy”
http://Wikipedia.org/wiki/sunflower galaxy. It is quite beautiful like the words we receive from Sunflower Seeds.

Dear Jan, This is so exciting. I went on line and saw pictures of this beautiful galaxy. Thank you and your son for bringing it to my attention! Sr. Melannie

Thank you sister for opening my eyes to appreciate this day, this minute, just how vast and incomprehensible God is. And, the amazing thing is, he still “makes time” to have a personal chat with me (and every one of his children) every day. I am humbled and so grateful for His presence in my life – Thanks for reminding me just “How Great Thou Art.”!
