What was that blue flash?

What is the bright light in space?
National Aeronautics and Space Administration (NASA) was able to capture the glow within three days using the Hubble Space Telescope but the results were baffling. Astronomers came across a unique celestial event as they discovered the brightest infrared light from a short gamma-ray burst ever seen.
How long does the Green Flash last?
between one and three seconds
Although the green flash usually lasts between one and three seconds, it was observed on and off for a full 35 minutes on October 16, 1929 by Admiral Byrd’s expedition at the Little America base on Antarctica.
What can cause a blue light in the sky at night?
The Short Answer: Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves.
Why is there a blue spot in the sky at night?
The blue field entoptic phenomenon is an entoptic phenomenon characterized by the appearance of tiny bright dots (nicknamed blue-sky sprites) moving quickly along squiggly lines in the visual field, especially when looking into bright blue light such as the sky.

Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white. The sunlight reaching us from low in the sky has passed through even more air than the sunlight reaching us from overhead.

The sky is only blue because when the sunlight lenses through our atmospheric gases, the light refracts and deflects into ionized blankets of electromagnetic intensity, like how a rainbow is formed, charging the atomic molecules within your physic…
