Twinkle twinkle little star, how I wonder what u are......
沒有人知道要發現和命名一顆星需要多少觀察力和耐性；沒有人理解要守護和成就一個人要多少承擔、信任，和遭遇多少委屈，還經歷多少次被誤解，被多少人當傻瓜。旁人，仍覺得你沒有盡力。儘管你也許是第一個看見那些隱約發出微弱光芒的星體，極力不讓他們還未被命名就消失，努力向世界證明這些星體的存在。
最近，因為連踩一星期，左眼肌肉發炎，突然不能向左或向右看，#自嘲是最高尚的幽默，我告訴醫生，我只能「向前看」。
在糢糊視野中，向閃閃發亮的星體許願。
總有一天，別人要知道您們的名字。

Sparkling Stars: Some cosmic objects move a little further than others - take the subject of this NASA/ESA Hubble Space Telescope image, a globular cluster of stars known as Palomar 12. Although it currently lies on the outskirts of the Milky Way's halo, Palomar 12 was not born here. When astronomers first studied this cluster, they were puzzled by its strangely young age when compared to the other clusters in the galaxy. It appeared to be around 30 percent younger than other Milky Way globulars. Surely if it had been born within our galaxy, it would have sprung to life at a similar time to its cluster companions?
A bit more digging revealed that Palomar 12 was actually ripped from its initial home, the Sagittarius Dwarf Elliptical galaxy, around 1.7 billion years ago via tidal interactions between its former home and our galaxy. The dwarf galaxy that Palomar 12 once called home is a satellite galaxy to ours, and closely orbits around us - even occasionally passing through the plane of our galaxy. In fact, it is being slowly torn apart and consumed by the Milky Way.
