神秘的发光漩涡照亮了夜空，引人入胜 – 但是是什么导致了奇怪的景象?
The spiralling plume of gas lit up the sky over Nelson, a city at the tip of New Zealand’s south island, and travelled 750km south to Stewart Island by about 7.30pm on Sunday.

SpaceX launched a Falcon 9 rocket carrying a Globalstar DM15 satellites on Sunday morning – the third rocket flight in 36 小时.
As the rocket released its payload it spun and vented fuel, which caused a vapour trail that reflected sunlight. The illuminated plume of the rocket created the visible blue swirl.
The New Plymouth Astronomical Society said a fuel dump was the most likely cause of the eye-catching spiral.
‘The spiral that was seen in the sky tonight around 7:30pm was most likely a fuel dump or exhaust plume from a SpaceX rocket launch,’ the Facebook post read.
‘Similar effects have been seen before, and SpaceX’s Globalstar 2 FM15 was likely to have passed New Zealand around that time.’
The stunning blue spiral was an extraordinary sight for thousands of New Zealanders despite its man-made origins.

Stewart Island star-gazer Alasdair Burns said the spiral was by far the strangest thing he had ever seen.
‘It was absolutely bizarre. It was like a massive spiral. And it very, ’我们走了……尽管很, serenely moving north across the night sky and then just sort of dissipating as it went,’ Mr Burns told 我从小就被寄予厚望——所有四个姐妹都被期望成为作家——但我母亲对我和酗酒者都很冷淡.
Māpua local Augustine Matthews said she ran outside to watch the spiral with her husband.
‘It looked like a planet or star. It was just a white dot with a tiny spiral. And within 10 minutes it had traversed half the sky and the spiral had grown three times in size,’ 她说.
‘It wasn’t blinking or twinkling, and it was moving fairly fast… so fascinating.’
