Astronomers confirmed that the comet identified as SWAN has reached its closest distance to the Sun. To observe the comet, an astronomy organization will host a live streaming event that will feature SWAN as it flies towards the massive star.

The comet, officially known as C/2020 F8, was first spotted on April 11 by the Solar Heliospheric Observatory (SOHO), a robotic satellite launched through a collaborative effort between NASA and the European Space Agency to study the Sun. The comet was spotted using the spacecraft's hydrogen-detecting instrument known as the Solar Wind ANisotropies, or SWAN.

The first color image of the comet C/2019 Q4 (Borisov), was captured by the Gemini North telescope at Hawaii's Mauna Kea. Gemini North acquired four 60-second exposures in two color bands (red and green). The blue and red lines are background stars moving in the background. Gemini Observatory/NSF/AURA/Travis Rector

Watching SWAN Approach The Sun

The comet has already reached its minimum distance from the Sun. The Virtual Telescope, an observatory based in Italy, will host a live streaming event that will show the comet during its flyby. According to the astronomy organization, the live stream will commence on May 28 at 7:00 p.m. UTC or at 3:00 p.m. EDT. It can be viewed through the video below or through Virtual Telescope's website. As noted by astrophysicist Gianluca Masi of the Virtual Telescope, watching a comet fly across space is an unforgettable experience. Through robotic telescopes, sky gazers will be able to watch as SWAN flies close to the Sun from the comfort of their homes.

"Comet C/2020 F8 Swan is now at its minimum distance from our Sun," he told Express. "We have been waiting for this opportunity for months, now the Virtual Telescope is ready to bring this superb view to you. We will observe comet C/2020 F8 Swan thanks to our robotic telescopes, sharing it live with the world, via the internet, making it possible for you to spot this cosmic snowball from your home."

Previous Observations On SWAN

As the comet flies close to the Sun, its magnitude or overall brightness will increase. Astronomers believe that the comet might become bright enough to be spotted from Earth using a pair of binoculars.

Previous observations on SWAN detected outbursts from its surface. According to experts, the outbursts do not necessarily mean that the comet is starting to break apart. Instead, the heat from the Sun is probably causing the comet's icy surface to vaporize.
