He added: "We saw two orange dots rise into the sky and disappear".
The sounding rockets, launched two minutes apart and reaching an altitude of 320 kilometres (198 miles) took measurements of the atmospheric density and temperature.
The April 8 launch is the first of eight sounding rocket missions set to be launched in aid of NASA's AZURE mission.
The display was part of a NASA-funded mission called the AZURE (Auroral Zone Upwelling Rocket Experiment), to learn about the flow of particles in the ionosphere and to find out more about the contribution that an aurora makes to the amount of energy leaving and entering Earth's geospace system.
New Zealand privacy watchdog calls Facebook ’morally bankrupt’
Australia hopes its law will be implemented by other countries, and Edwards suggested that New Zealand follow the example. Facebook co-founder and CEO Mark Zuckerberg testifies before the House Energy and Commerce Committee on April 11, 2018.
The eye-catching lights were created by releasing two harmless gases into the atmosphere - trimethylaluminum as well as a mixture of barium and strontium - so researchers can study the paths of particles in the Earth's ionosphere, NASA says. The vapors were released over the Norwegian Sea at 71 through 150 miles altitude. According to the USA space agency, the movement of the colorful clouds and their dispersion allowed scientists to observe the flow of particles in two key regions of the atmosphere. Those colorful undulating sheets of the aurora borealis are the heavenly product of collisions between Earth's atmosphere and particles from the Sun. Glowing Lights In The Sky The mission posed no harm to the residents of northern Norway, but the launches caused a bit of a panic among people who were not expecting to witness the artificial light show this weekend.
"It looked like an alien attack", said Michael Theusner, who captured the freakish sight while filming the Northern Lights.
Skygazers in Norway and Sweden were surprised when they saw unusual blue lights in the sky in the wee hours of Saturday morning.
This visually striking experiment allowed scientists to observe the behaviour of upper-level winds and the movement of particles in this unfamiliar part of our atmosphere. NASA is planning another seven rocket launches in Norway over the next two years, so more alien panic could be expected.
