Art Works that Redefine Arts and Light at Noor Riyadh Festival

Noor Riyadh festival, which is held in 13 locations in the Saudi capital, aspires to send a message of hope and promote environmental sustainability to the people of Riyadh.

Twenty-six major artists from more than 20 countries across the globe- 40 percent of them Saudis- will participate in the lighting festival on Thursday, which is scheduled to run for 17 days.

Among the names taking part in the festival are the French conceptual artist Daniel Buren and the two Russian artists Ilya and Emilia Kabakov. Germany's Carsten Holler, as well as Yayoi Kusama and Dan Flavin will also be part of the festival.

Rashed Al-Shashai, Lulwah Al-Homoud, Ahmed Mater, Ayman Al-Zedani, Maha Malluh, Dana Awartani, Marwah Al-Mugait, Ali Al-Razza'a, Sultan bin Fahad and Talal Al-Zeid are among the Saudi names that will take part in the festival.

Additionally, the work of the late artist Muhammad Al-Salim, a pioneer in plastic art, will be on display in the exhibition.

Al-Shashai, whose artwork is known to highlight the human existence and the functions of society, told Asharq Al-Awsat about his artwork that will be on display at the festival.

"My work will be under the theme Searching for Darkness."

Al-Zedani pointed out to Asharq Al-Awsat that the festival will be a platform for global cultural exchange, making it a fertile environment for cooperation, learning and entertainment.

He explained that his work is a film under the theme "Earthseed," a three-channel installation video commissioned by the Royal Commission for Riyadh. The short film blends real science and futuristic science fiction to speak about the effects of climate change on the region.

Al-Homoud is proud of taking part in the festival alongside an array of artists from the Kingdom and the world. She indicated that working on her piece has been a new experience, as it is an interactive mobile piece that allows viewers to exist in a world of lines and abstract shapes whose movement resembles that of the universe. An animation displayed on a circular screen, the idea is based on language and the relationship between the finite and the infinite, as it starts from a single point and moves to meanings and ideas without limits.

Malluh submitted a series or group of photographs, "Capturing Light", and she tells Asharq Al-Awsat: "Since I started working with traditional black and white photography, and over the years, I became very interested in the relationship between light and shadow, and the lack of possibilities and places in my city. I built a darkroom for development in order to develop and print my own photos. For me, it was the only way to control both the quality and content, which are the most important qualities in the production of fine art. My fascination with photography grew and developed through my interest in combining collage and photography."

Astronomers have spotted orbiting around a young star a newborn planet that took only 3 million years to form - quite swift in cosmic terms - in a discovery that challenges the current understanding of the speed of planetary formation.
This infant world, estimated at around 10 to 20 times the mass of Earth, is one of the youngest planets beyond our solar system - called exoplanets - ever discovered. It resides alongside the remnants of the disk of dense gas and dust circling the host star - called a protoplanetary disk - that provided the ingredients for the planet to form.
The star it orbits is expected to become a stellar type called an orange dwarf, less hot and less massive than our sun. The star's mass is about 70% that of the sun and it is about half as luminous. It is located in our Milky Way galaxy about 520 light-years from Earth, Reuters reported. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).
"This discovery confirms that planets can be in a cohesive form within 3 million years, which was previously unclear as Earth took 10 to 20 million years to form," said Madyson Barber, a graduate student in the department of physics and astronomy at the University of North Carolina at Chapel Hill and lead author of the study published this week in the journal Nature.
"We don't really know how long it takes for planets to form," UNC astrophysicist and study co-author Andrew Mann added. "We know that giant planets must form faster than their disk dissipates because they need a lot of gas from the disk. But disks take 5 to 10 million years to dissipate. So do planets form in 1 million years? 5? 10?"
The planet, given the names IRAS 04125+2902 b and TIDYE-1b, orbits its star every 8.8 days at a distance about one-fifth that separating our solar system's innermost planet Mercury from the sun. Its mass is in between that of Earth, the largest of our solar system's rocky planets, and Neptune, the smallest of the gas planets. It is less dense than Earth and has a diameter about 11 times greater. Its chemical composition is not known.
The researchers suspect that the planet formed further away from its star and then migrated inward.
"Forming large planets close to the star is difficult because the protoplanetary disk dissipates away from closest to the star the fastest, meaning there's not enough material to form a large planet that close that quickly," Barber said.
The researchers detected it using what is called the "transit" method, observing a dip in the host star's brightness when the planet passes in front of it, from the perspective of a viewer on Earth. It was found by NASA's Transiting Exoplanet Survey Satellite, or TESS, space telescope.
"This is the youngest-known transiting planet. It is on par with the youngest planets known," Barber said.
Exoplanets not detected using this method sometimes are directly imaged using telescopes. But these typically are massive ones, around 10 times greater than our solar system's largest planet Jupiter.
Stars and planets form from clouds of interstellar gas and dust.
"To form a star-planet system, the cloud of gas and dust will collapse and spin into a flat environment, with the star at the center and the disk surrounding it. Planets will form in that disk. The disk will then dissipate starting from the inner region near the star," Barber said.
"It was previously thought that we wouldn't be able to find a transiting planet this young because the disk would be in the way. But for some reason that we aren't sure of, the outer disk is warped, leaving a perfect window to the star and allowing us to detect the transit," Barber added.
