Watch: BRIAN MAY, SERJ TANKIAN And JEFF SCOTT SOTO Perform QUEEN's 'The Show Must Go On' At STARMUS Festival

Earlier today (Wednesday, September 7),QUEEN guitarist Brian May teamed up with SYSTEM OF A DOWN frontman Serj Tankian, SONS OF APOLLO vocalist Jeff Scott Soto, Graham Gouldman and opera singer Montserrat Martí to perform the QUEEN classic "The Show Must Go On" with the Armenian National Orchestra at the sixth edition of the Starmus festival in Yerevan, Armenia. Video of the performance can be seen below (courtesy of Victims Of A Down).

Starmus festival features presentations by legendary astronauts, Nobel Prize winners, prominent figures of science, technology, culture and arts.

Every edition of the festival is organized around a particular theme related to space exploration, and this year's topic is "50 Years On Mars".

May, who is an astrophysicist and Starmus co-founder, has performed at virtually all previous editions of the festival.

"Starmus VI: 50 Years On Mars" is dedicated to the 50th anniversary of the first soft landing on Mars by "Mars 3" and the first orbiter "Mariner 9". "Mariner 9" took the first high-quality images of Mars while "Mars 3" brought the first rover, Prop-M, to the surface of Mars.

The Starmus advisory board includes Dr. Brian May, Emmanuelle Charpentier, Jill Tarter, Peter Gabriel, Richard Dawkins and Tony Fadell.

Speakers at Starmus VI include world-renowned astronauts, including social media-sensation Chris Hadfield; Charlie Duke (Apollo 16),the youngest man to walk on the moon; Jim Bagian, a former astronaut of Armenian descent; and Charles Bolden Jr., the former head of NASA. In addition, Starmus features a wide selection of Nobel Laureate scientists such as Kip Thorne, Emmanuelle Charpentier, Donna Strickland, iPod creator Tony Fadell and physicist and science communicator Brian Greene. Other musicians include rock band SONS OF APOLLO, legendary keyboardist Rick Wakeman, revered jazz pianist Tigran Hamasyan and Andrey Makarevich, founder of Russia's oldest active rock band, amongst other celebrities and renowned scientists.

Stephen Hawking, one of the most influential scientists of the 20th and early 21st centuries, was a Starmus advisory board member and became the inspiration for an ambitious award in 2016 that recognizes the merit of popular science at an international level. The Stephen Hawking Science Medal awarding ceremony is one of the key events of the festival, aimed at promoting science to everyone. Previous winners of the medal have included Hans Zimmer, Neil deGrasse Tyson, Buzz Aldrin and Brian Eno.

Armenia was selected for its contribution to astronomy, astrophysics and space exploration. For much of the 20th century, it was home to the Soviet space program, and to this day it remains a key location for the international community, housing The Byurakan Astrophysical Observatory and the Aragatz Station.

Starmus co-founder Garik Israelian says: "Armenia has played an extraordinary role in the past, present and future of how we understand and explore our universe, and I'm looking forward to welcome this extraordinary range of thinkers and creatives to encounter this special place and share ideas."
