Galaktikamizdan tashqarida aniqlangan ilk sayyora
Astronomers say they have found the first planet that came from out of our galaxy. The planet is similar to Jupiter and once belonged to a galaxy that was consumed by our Milky Way. Astronomers in Chile discovered the new planet with a powerful telescope. The new planet is revolving around a star, called HIP 13044. It is about 2.000 light year away from earth and once belonged to a neighboring galaxy, which was swallowed up by the Milky Way about 6 billion years ago. The planet, about the size of Jupiter, travels closely around its sun in an orbit that takes 16 days to complete. Up to now, astronomers have discovered 500 planets, all of which have their origin in Milky Way. The new discovery gives scientists proof that many more planets may exist outside our own galaxy. HIP 13044 is in its dying phase. The star has turned into a red giant, consumed all of its fuel and is getting larger and larger. It has eaten up all of its planets, but obviously only one survived. This discovery can be helpful to scientists in showing them what may happen in our own solar system when our sun is expected to become a red giant in about 5 billion years. Astronomlarning aytishiga ko'ra, ular galaktikamizdan tashqaridan kelib qolgan ilk sayyorani topishgan. Sayyora Yupiter sayyorasiga o'xshash bo'lib, ilgari Somon yo'li galaktikasi tufayli yo'q bo'lib ketgan qaysidir galaktikaga oid bo'lgan. Chili astronomlari ushbu yangi sayyorani yuqori quvvatli teleskop yordamida kashf qilishdi. Yangi sayyora HIP 13044 deb ataluvchi yulduz atrofida aylanib turibdi. U Yer sayyorasidan chamasi 2000 yorug'lik yili uzoqligida joylashgan bo'lib, qachonlardir taxminan 6 milliard yil avval Somon yo'li tomonidan tortib olingan qo'shni galaktikaga taalluqli bo'lgan. Taxminiy kattaligi Yupiterga teng bo'lib, o'z Quyoshiga yaqin masofada bir marta aylanib chiqish uchun 16 kun sarflanadigan orbita bo'ylab harakatda bo'ladi. Hozirgi kungacha astronomlar barchasining kelib chiqishi Somon yo'lidan bo'lgan 500 ta sayyorani kashf qilishgan. Yangi kashfiyot olimlarga o'z galaktikamizdan tashqarida boshqa ko'plab sayyoralar mavjud bo'lishi mumkinligini isbotlaydi. HIP 13044 so'nish pallasidadir. Ushbu yulduz "qizil gigant"ga aylanib qolgan, butun quvvatini sarflab bo'lgan va tobora yiriklashib bormoqda. U o'zining atrofida aylanuvchi sayyoralarini yo'q qilib bitirgan, biroq shunisi aniq bo'ldiki, ulardan biri saqlanib qolibdi. Ushbu kashfiyot olimlarga o'z quyosh sistemamizda ham taxminan 5 milliard yil ichida "qizil gigant"ga aylanishi kutilayotgan Quyoshimiz ham shu holatga tushganida nimalar sodir bo'lishi mumkinligini ko'rsatishda qo'l kelishi mumkin.
