代寫論文價碼:為什麼要觀察太空
為什麼天文學家把望遠鏡放在太空?正是在所有的電磁光譜中,宇宙不斷地向我們發出光。然而,大部分的輻射或光並沒有到達地球表面。某些種類的輻射被我們的大氣層所阻擋,它只允許某些種類的射線。地球上人類賴以生存的大氣層阻擋了伽馬射線、x射線和大多數紫外線等高能量有害輻射。大部分紅外輻射被大氣吸收。然而,地球的大氣層對大多數無線電波、可見光和紅外區域的小窗都是透明的。這些地面天文台提供了對空間物體進行長期研究的寶貴資料。然而,穿過大氣層的光只能被這些天文台探測到。大多數時候,我們對宇宙的了解來自於空間中物體發出的光。通過利用從所有波長發送給我們的數據,對所有的光進行檢查,從而獲得神秘而神奇的宇宙的完整圖像是很重要的。因此,向太空發射天文台是非常必要的,這樣才能到達地球大氣層以上,而地球大氣層是不允許大部分數據到達地球的。

天文學家為了從沒有到達地球表面的光中收集數據,依靠了高空氣球、高空飛行的飛機、深空和地球軌道上的衛星以及安裝在航天飛機貨艙裡的望遠鏡。由於能夠在太空中發射望遠鏡和技術的迅速進步,多波長天文學的前景極為光明。在未來的時間裡,人們可能會聽到在這個光譜中觀察到的各種各樣的新發現。核光譜望遠鏡陣列允許天文學家在高能x射線中研究宇宙,是一項探索者任務。 2012年6月發射的NuSTAR是地球軌道上第一個聚焦硬x射線的望遠鏡(Chaisson 1995)。與已經觀測到這一電磁頻譜區域的最大的地面天文台相比,預計NuSTAR的性能將大大超過它們。天體物理學任務的重點是探索光譜中其他區域的宇宙;NuSTAR對他們來說是一個非常有用的設備。

Why astronomers put telescope in space?It is all across all the electromagnetic spectrum that the Universe keeps on sending us light. However, most of this radiation or light does not reach the surface of the Earth. Certain kinds of radiations are blocked by our atmosphere and it allows only certain kinds of rays. Our atmosphere for survival of beings on earth blocks out high-energy harmful radiation like gamma rays, X-rays and majority of UV rays. Most of the infrared radiations are absorbed by atmosphere. However, the atmosphere of the earth is transparent to most of the radio waves, visible lights and small windows in the infrared regions. Valuable information for long-term studies of objects in space is provided by these ground-based observatories. However, the light which passes through the atmosphere is only detected by these observatories. Most of the times, our leaning about the universe is from the light which is emitted by the objects in the space. It is essential to examine all of the lights so as to get the completed picture of the mysterious and amazing universe, by utilizing the data sent to us from all the wavelengths. Hence, it is essential to send observatories in the space in order to get above the atmosphere of the Earth which does not allow most of the data to reach us.

Astronomers, in order to gather data from the light which does not reach the surface of the earth, have relied on high-altitude balloons, airplanes flying at high altitudes, satellites in the deep space and orbit of the earth and on telescopes mounted in the cargo bay of the Space Shuttle. The future is extremely bright for the multi-wavelength astronomy because of the ability to send telescopes in the space and rapid advancements of technology. In the time to come, one might be able to hear about various kinds of new discoveries being observed in this spectrum.The Nuclear Spectroscopic Telescopic Array allows astronomers to research and study about the universe in the high energy X-rays and is an Explorer mission. NuSTAR which was launched in June 2012 is the first telescope in the orbit of the Earth which focuses hard X-ray (Chaisson 1995). As compared to the largest observatories based on ground which have seen this region of the electromagnetic spectrum, it is expected that NuSTAR would greatly exceed in terms of performance. The astrophysics missions focus on exploring the cosmos in the other regions of the spectrum; NuSTAR is a very useful device to them.
