University Study Prompts Astronomers To Photograph Tailless Comet's Close Encounter With Earth

A comet without its tail is set to pass by Earth in the coming days, as per a recent report by the Daily Mail. Experts from the University of Reading in the UK have confirmed that the C/2021 S3 Pannstars comet will make its journey past Earth. Astronomers are being encouraged by university researchers to photograph this event using their cameras, as they believe that studying this tailless comet can provide valuable insights into solar wind conditions, shedding light on this crucial aspect of space weather.

Solar winds, composed of charged particles emitted by the Sun, pose potential risks to both satellites in space and Earth’s technology. The University of Reading likens comets to cosmic windsocks, capable of revealing the direction and strength of solar winds. Scientist Sarah Watson elaborates that comets with tails may not provide reliable indicators of solar wind, whereas tailless comets offer precise information about wind direction and intensity, unaffected by external factors. Gathering sufficient data will require multiple images and tracking of the comet’s trajectory, prompting amateur astronomers to utilise their telescopes to document this cosmic event.

Watson talks about the importance of taking numerous timed photos of the comet to accurately monitor its path through the solar system. This presents a significant opportunity for amateur astronomers to contribute to scientific research by capturing images of the comet and sharing them with researchers at the University of Reading.

Assuring the public, scientists confirm that the approach of the C/2021 S3 Pannstars comet poses no threat to Earth. Visible in the night sky since February 14th, it will remain observable until the end of March, becoming increasingly visible as it moves away from the Sun. However, viewing it without telescopes or binoculars is unlikely.

For those aiming to capture high-quality images of the comet, astronomers recommend using a camera with a large lens connected to a small telescope. Watson advises taking multiple timed photos to closely monitor the comet’s journey through the solar system. Individuals who successfully photograph the comet are encouraged to share their images with scientist Sarah Watson at the University of Reading.
