與氧波段中的玫瑰星云，由Arno Rottal拍攝。
來源：https://apod.nasa.gov/apod/ap150225.html
玫瑰星云并非宇宙中唯一可以讓人聯想到花的氣體和塵埃的宇宙云，但它是最著名的。玫瑰星云位于麒麟座(Monoceros)大分子云團邊緣，距離我們約為5000光年。玫瑰星云中心區域編錄號為NGC 2237，直徑約50光年。朝著麒麟座方向，使用小型望遠鏡中就能看到這團星云。
玫瑰星云，上圖右側區域為NGC 2237。
天520，有些人在思考如何脫單，有些人在思考如何表白，有些人在思考如何秀恩愛，可今天還要上班怎么破？
其實很多時候禮物不一定就需要花錢買，今天我們就用代碼來一次表白吧，把你中意的代碼發給她，看她能不能看懂，哈哈哈！
一、入門級
print('\n'.join([''.join([('Love'[(x-y)%4]if((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3<=0 else' ')for x in range(-30,30)])for y in range(15,-15,-1)]))
