Srimad Bhagavatam Canto 02, Chapter 02, Text 26

SB 2.2.26

atho anantasya mukhanalena
dandahyamanam sa niriksya visvam
niryati siddhesvara-yusta-dhisnyam
yad dvai-parardhyam tad u paramesthyam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
At the time of the final devastation of the complete universe [the end of the duration of Brahma’s life], a flame of fire emanates from the mouth of Ananta [from the bottom of the universe]. The yogi sees all the planets of the universe burning to ashes, and thus he leaves for Satyaloka by airplanes used by the great purified souls. The duration of life in Satyaloka is calculated to be 15,480,000,000,000 years.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
It is indicated herein that the residents of Maharloka, where the purified living entities or demigods possess a duration of life calculated to be 4,300,000,000 solar years, have airships by which they reach Satyaloka, the topmost planet of the universe. In other words, the Srimad-Bhagavatam gives us many clues about other planets far, far away from us which modern planes and spacecraft cannot reach, even by imaginary speeds. The statements of Srimad-Bhagavatam are accepted by great acaryas like Sridhara Svami, Ramanujacarya and Vallabhacarya. Lord Sri Caitanya Mahaprabhu specifically accepts Srimad-Bhagavatam as the spotless Vedic authority, and as such no sane man can ignore the statements of Srimad-Bhagavatam when it is spoken by the self-realized soul Srila Sukadeva Gosvami, who follows in the footsteps of his great father, Srila Vyasadeva, the compiler of all Vedic literatures. In the creation of the Lord there are many wonderful things we can see with our own eyes every day and night, but we are unable to reach them equipped by modern materialistic science. We should not, therefore, depend on the fragmentary authority of materialistic science for knowing things beyond the range of scientific purview. For a common man, both modern science and Vedic wisdom are simply to be accepted because none of the statements either of modern science or of Vedic literature can be verified by him. The alternative for a common man is to believe either of them or both of them. The Vedic way of understanding, however, is more authentic because it has been accepted by the acaryas, who are not only faithful and learned men but also liberated souls without any of the flaws of conditioned souls. The modern scientists, however, are conditioned souls liable to so many errors and mistakes. Therefore the safe side is to accept the authentic version of Vedic literatures, like Srimad-Bhagavatam, which is accepted unanimously by the great acaryas.
