Teleskop Terbesar di Luar Angkasa: Hubble

Mengintip Luar Angkasa Melalui Lensa - Lensa Teleskop Hubble

Ahmad Dahlan.  Teleskop Hubel merupakan sebuah teleskop raksasa yang diletakkan di laur angkasa. Nama Huble sendiri terinspirasi dari seorang ilmuwa berdarah Amerika, Edwin Hubble yang banyak berjasa dalam bidang pengamatan luar angkasa dan lensa melalui hukum Hubble. Teleskop Huble telah membantu manusia memahami karakteristik dari alam semesta melalui gambar-gambar yang dikirimkan dari stasiun ruang angkasa ke Bumi.

Sejarah Pembuatan Teleskop Hubble

Pembangunan sebuah Teleskop yang diletakkan pertama kali diajukan oleh Akademi Sains Nasional Amerika Serikat pada tahun 1962. Tujuan dari pembangunan ini untuk melakukan pengamatan langsung dari luar angkasa agar terhindar dari polusi cahaya yang dibuat oleh manusia dan juga pembiasan yang terjadi di Atmosfer bumi. Manfaat dari pembangunan diharapkan mampu membantu manusia mendapatkan data yang sangat presisi dan panjang gelombang elektromagnetik yang dikelaurkan bintang-bintang dan objek-obejk lain di alam semesta. 

Pembangunan Teleskop Hubble kemudian mendapatkan respon dari kongres Fisika tahun 1977 untuk mendirikan sebuah teleskop raksasa diserta dengan stasiun luar angkasa sebagai tempat teleskop. Stasiun ini kemudian dijaga agar tetap bergerak pada orbit bumi. Pembangunan kemudian dilakukan pada tahun yang sama setelah dana awal terkumpul.

Kosntruksi lengkap dari telskop Hubble baru berhasil dilakukan pada tahun 1985 kemudian dikirim ke luar angkasa pada tanggal 24 April 1990. 4 Tahun lebih lama dari rencana awal pengorbitan Hubble yakni tahun 1986. Penundaan ini tidak lain disebabkan oleh kecelakaan pesawat Chalengger.

Beberapa tahun setelah dioperasikan, HUbble akhirnya berhasil mengirim gambar ke Bumi namun hasil yang ditunjukkan adalah gambar buram. Nasa kemudian menemukan penyebab buramnya gambar tersebut disebabkan oleh pergeseran Lensa Utama sejauh 1/50 ketebalan rambut atau sekitar 0,02 mm. NASA baru dapat mengirim Astronot untuk melakukan perbaikan dan menambahkan beberapa bagian untuk memperbaiki kesalahan tersebut pada bulan Desember 1993.

Teleskop terbesar di dunia unik untuk melihat sesuatu yang tidak terlihat

Ukuran Teleskop Hubble

Badan Teleskop: Hubble memiliki panjang sekitar 13,1 meter dengan diameter mencapai 4,27 meter. Total massa seluruh komponen dari Hubbel mencapai 11 Ton. Dengan ukuran ini Hubble memiliki ukuran hampir sama dengan Bus.

Lensa : Lensa utama pada Huble memiliki jari jari kelengkungan sebsar 1,2 meter dengan massa 826 kg. Bahan utama dari lensa adalah kaca silika dengan lapisan Aluminium murni. Aluminium akan berfungsi merefleksikan cahaya. Lapisan Maganesium Flourida diberikan pada lensa untuk mengurangi kerusakan lensa yang diakibatkan oleh sinar Ultraviolet dan proses oksidasi.

Cara Kerja Teleskop Hubbel

Teleskop Hubbel bekerja dengan cara menangkap gambar. Gambar kemudian disimpan dalam bentuk kode digital lalu dipancarkan ke bumi melalui sebuah antena dengan kecepatan mengirim 1 Juta bit per detik.  Kode digital yang diterima oleh stasiun bumi kemudian diubah menjadi foto dan spektograf yakni sebuah instrumen yang digunakan untuk mencatat spektrum astronomikal.

Hubble mengelilingi Bumi dengan kecepatan 5 mil per deti, dengan kecepatan ini, Hubble akan menempuh 150 juta mil dalam setahun atau setara dengan 241 juta kilometer. Hubble dikendalikan melalui bumi dari Goddard Space Fligth Center di Greenbelt.

Hasil pengematan Teleskop Hubble

Hubbel memiliki peran penting dalam perkembangan ilmu astronomi serta kaitannya dalam mengamati perkembangan tentang universe dan berbagai benda-benda yang ada diangkasa seperti bintang, galaksi dan juga black hole. Salah satu penemuan  penting dari Hubble adalah Eris yang merupakan sebuah planet katai dengan satu buah satelit Dysnomia. Penemuan ini menjadi dasar keluarnya Planet Pluto dalam sistem tata surya.

Selain dari benda-benda yang ada di dalam tata surya, Hubbel juga mengamati kejadian-kejadian luar angkasa yang tidak dapat diamati dari bumi seperti Supernova, proses lahirnya bintang dan tabrakan bintang. Penemuan memberikan dukungan kepada para ilmuwan bahwa Matahari yang kelihatannya memiliki sinaar abadi suatu saat akan mengalami sekarat dan mati.

  1. My knowledge about out of the space is increase by read this article, i never know that there is a big telescope that round this earth if i dont read this article. But i wonder how the result of this telescope take a picture of the space maybe the writer can put the result of katai planet and dysnomia satelit so i can know how the quality of the picture taken by this hubble telescope.

  2. I want to ask you sir. The complete construction of the hubble telescope was delayed due to a chalengger aircraft crash. Why this plane crashed? Was the plane carrying this telescope and then an accident?

  3. This article is very interesting in my opinion. And hubble telescope is also very remarkable. What caught my attention was that I could observe black holes. Hopefully later the black hole can be studied more deeply because some articles that I can still no one knows in detail about this black hole. That is my hope hehe

  8. After reading this article, In addition to the knowledge of telescopes added, this article also makes me imagine. I imagine how big and heavy the hubble telescope. I also became aware that the lens shift so far only 1/50th of hair thickness can be the cause of blurred images. You should re-read this article and correct the word (typo), sir. Hehehe 😂

  9. From this article I got more knowledge is about telescope, the hubble telescope have a characteristics, can observe space events that cannot be observed from the earth like a supernova, process of the birth of star and star collisions. The hubble telescope is also used a long time start from planning to operation, the hubble telescope also have a big size and speed fast enough.

  15. It was the best article that i ever read before, because the article tell us about Hubble's discoveries have transformed the way scientists look at the universe. Its ability to show the universe in unprecedented detail has turned astronomical conjectures into concrete certainties. It has winnowed down the collection of theories about the universe even as it sparked new ones, clarifying the path for future astronomers.

    That's an interesting article. So far, we only know about the normal telescope and how to apply formulas to get the magnification, diameter, focus lens, objective lens, etc. We would never know that there's largest telescope in the space: Hubble, if you don't share this information. I hope you could share more information and knowledge in the future.
