Amateur Astronomer Captures 30-Day Collage of Venus and Jupiter's Conjunction Over Kolkata

A Month-Long Dance of Planets: Capturing Venus and Jupiter in the Night Sky

Amateur astronomer and avid photographer, Soumyadeep Mukherjee, has gifted everyone with a breathtaking 30-day photographic record of Venus and Jupiter's celestial dance. The captivating series of images, aptly named "Closer, Everyday", showcases the gentle movement of these two planets in the evening sky above Kolkata, India, leading up to a dramatic planetary conjunction.

Employing a high-quality digital camera coupled with a 50 mm lens, Mukherjee successfully captured the planets' movement within the Gemini constellation, shortly after sunset each day between mid-May and early June. The planets Venus and Jupiter were seen in close proximity in the western heaven.

Photography Challenges and Techniques

Mukherjee predominantly took the pictures during the civil twilight phase to highlight the fluctuating colors of the evening sky along with the planets. However, he had to adapt his shooting schedule on certain days due to cloudy weather, capturing images during the nautical and astronomical twilight instead.

Throughout the photography project, Mukherjee maintained a steady approach, adjusting only the shutter speed to accommodate the changing light conditions. This resulted in an enchanting portrayal of the planets' journey. "To capture the images, the camera was kept level to the horizon, and the planets were aligned at the center of the frame as much as possible," he explained. "The images were shot using the same camera and lens, with a consistent focal length."

The Planetary Progression

The sequential shots vividly tracked the persistent movement of Jupiter and Venus as they orbited the sun, while seeming to inch closer to each other in our earthly view. The graceful dance reached its top crescendo on the final day of the project — which can be seen in the far-right panel — as Jupiter and Venus appeared less than 2 degrees apart in the western sky, delivering a dramatic planetary conjunction spectacle for skywatchers everywhere.

In reality, this close approach of Jupiter and Venus is a fascinating illusion of perspective. Throughout the 30-day project, Venus was actually extending its distance from Jupiter, adding an additional 27 million miles (43 million kilometers) between them as it hastened towards Earth.

Join the Journey

For those inspired to embark on their own astrophotography journey, it's possible to capture stunning photos of the night sky. Key tips include investing in a good camera and lens suited for astrophotography, and learning about the ideal times and conditions for photographing the post-sunset sky.
