最靚嘅行星？
相信大家都可能聽過早前有位年僅17歲嘅NASA暑期實習生發現咗一顆名為TOI 1338 b嘅「少女色星球」??依粒行星顏色好夢幻，吸引咗唔少人關注，網上亦廣泛流傳佢嘅「相」。噉其實依粒行星有咩咁特別呢？佢嘅外貌係咪真係咁少女、夢幻呢??♀??♀
好遺憾，其實網上流傳嘅「相」並非真係一張相??因為依粒行星距離地球1300光年，而大細亦只係地球嘅6.9倍，以現時科技根本無法幫佢影相❌❌其中一張流傳嘅相，其實係透過Squids-among-stars生成出嚟??佢係一個喺內華達大學（University of Nevada）修讀計算機科學與工程嘅學生創建嘅bot??
張相其實喺TOI 1338 b被發現前嘅幾個月就已經生成咗出嚟，而NASA網頁入面TOI 1338 b嘅動畫亦只係透過電腦軟件摸擬氣體行星出嚟嘅效果??所以粒行星到底係唔係少女粉紅色，實在要等科技更加成熟，試下探測佢嘅成分、大氣活動，先有機會模擬得更準確??????
噉既然唔知佢靚唔靚，呢個行星有咩特別之處呢??TOI 1338 b，由Wolf Cukier發現。佢透過分析TESS（Transiting Exoplanet Survey Satellite凌日系外行星巡天衛星）依個太空望遠鏡所傳送畀地球嘅數據??留意到TOI 1338系統入面，唔單只有2粒恆星彼此兜圈??仲有TOI 1338 b依粒行星圍住佢哋公轉??
即係話，如果我哋住喺上面，就會好似星球大戰入面嘅天行者故鄉噉，每日睇到2個日落??依種行星就叫做環聯星運轉行星（circumbinary planet）。
噉啫係咩呢？我哋身處嘅太陽系裏面，太陽係恆星??而水星、火星、地球等八大行星就圍住太陽公轉。當2粒恆星圍住同一點（質心）轉，依個恆星系統就叫做聯星系統（binary star）。如果有行星圍住依對聯星轉??粒行星就叫環聯星運轉行星。
已被確認嘅環聯星運轉行星得非常之少????只有不足30粒。而TOI 1338b係第一個透過TESS發現嘅環聯星運轉行星??即使未必係夢幻少女色，我哋都不得不佩服嗰位實習生對數據嘅觀察力呀??♂??♀亦都期待假以時日，科技更成熟之時，可以更進一步分析TOI 1338b上面嘅成分，睇下佢係咪真係夢幻少女色??

The Most Beautiful Planet?
As everyone might have heard of through internet recently, there was a 17 years old intern in NASA who discovered the ‘TOI 1338 b’ exoplanet. The stunning appearance of the planet has attracted many people’s attention, ?? and its photos are spread virally around the world. So, what is so special about this planet? Does it actually look that fascinating? ??♀??♀
Unfortunately, with the current technology, it is essentially impossible to take photos of this planet using cameras due to its distance from Earth. ❌❌ TOI 1338 b is 1300 light years away from us, and its size is only 6.9 times the size of Earth. That photo on internet was actually made by a computer science engineer from the University of Nevada via ‘squids-among-stars’, ?? a bot that generates photos of distant planets. ??
The photo was in fact generated three months prior to the exoplanet’s discovery. Moreover, the animation of the TOI 1338 b on NASA website was only the virtual effect from the gas-planet-modelling-software. ??
Therefore, the physical appearance of the exoplanet is still yet to be known. We need to have a more advanced technology to explore on the characteristics of the planet, in order to obtain a more accurate virtual model of this TOI 1338 b exoplanet. ??????
Now that we know the planet does not look like this, what is so special about it then? ??
In fact, this so called TOI 1338 b exoplanet was discovered by Wolf Cukier, a teenage intern from the Scarsdale High School who was analysing the space telescope TESS (Transiting Exoplanet Survey Satellite). ?? He noticed that not only is there 2 stars in the TOI 1338 system, but also the exoplanet TOI 1338 b, which orbits around the binary stars. ??
