Photographer Captures Rare Atmospheric Phenomenon: Green Flash Emitted by Planet Venus Over Sweden

Photographer Captures Rare Green Flash from Venus in Sweden Sky

A photographer captured a unique scene of the planet Venus briefly emitting a green light in the skies of Sweden, in what is considered a rare atmospheric optical phenomenon.

Observing Venus’ Green Flash

While trying to capture images of Earth’s “evil twin” and the moon rising over Stockholm, Peter Rosen noticed the shimmering flash that had only been observed a few times.

What Causes Green Flashes?

Green flashes of light are caused by light reflecting off the Earth’s atmosphere like a prism (a transparent medium like glass), and only occur on cold, clear nights because fresh, clean air allows the light to escape.

How to View Venus’ Green Corona

For those who want to view Venus’ green corona, this could be possible using some settings, such as a high-speed camera with a very large sensor. By snapping photos in quick succession during a Venus sunset, it may be possible to capture this stunning view.

Factors Affecting Visibility

However, green lights are only visible on clear nights and when there are sharp gradients in air temperatures, such as extreme cold or extreme heat, which amplifies one color at the expense of another.

Venus’ Green Light Through the Atmosphere

Rosen said For Spaceweather.com He was able to catch the green flash “because of the extreme cold that persists over southern Sweden.” The green flash appeared when Venus tilted at an angle closer to Earth’s horizon, causing the Earth’s atmosphere to split white light into red, green, yellow, orange, and blue colors.

Implications of Pollutants on the Green Flash

If the atmosphere were entirely clean and free of pollution, the flash of color emanating from the planet Venus would be blue. However, since the air contains pollutants, the second color reflected is green.

Previous Sightings of Venus’ Green Flash

Venus’ green light has been captured a few times, including by Colin Legg in 2017. Another green flash on Venus was captured in Rome in 2018 by Paolo Palma, who used his smartphone in the lens of a 12-inch telescope and zoomed in 76 times. Although other green flashes have been observed, Rosen’s image of Venus “may be the best ever,” according to Spaceweather.com.

Conclusion

It is truly fascinating to witness such a rare and extraordinary phenomenon in our night sky, and the photographs captured by individuals like Peter Rosen contribute significantly to our understanding and appreciation of these beautiful natural occurrences.
