![]() ![]() ![]() It’s a matter of stability, research by University of California, Riverside, physicist Nathaniel Gabor suggests. Other grasses can turn “blue” (really more like a dark green) because of drought.įor maximum efficiency, grass should be black so it absorbs all light. Jason Pick of the Alberta Turfgrass Research Foundation at Olds College said in an email that researchers describe blue fescue as “blue,” although it’s more of a silvery-green. Specific types of grass are “blue” if you’re a turfgrass scientist. This is because plants get the most energy from photosynthesis from blue light if they reflected blue, they would be at an evolutionary disadvantage. 'Blue' grass?īlue-leafed plants are extremely rare on Earth outside of tropical rainforests, writes University of Adelaide biologist Andrew Lowe. This “ airglow” results in a green sky, but it’s such a faint green that you’re not likely to notice it unless you’re in orbit or taking a long-exposure photo. “When oxygen is hit by one of these fast moving particles, it gives off a green light,” Rosolowsky said - the result of the boosted electrons shedding a specific quantum of energy as green photons as they return to stability.Ī similar phenomenon happens when oxygen atoms get ionized by ultraviolet (UV) light in the day and regain their electrons at night, emitting green light in the process, Rosolowsky noted. Auroras happen when high-energy particles from the sun smack into Earth’s atmosphere, boosting electrons in molecules to unstable energy levels. You can also get green skies from aurora, Rosolowsky said. Droplets during severe thunderstorms can also create green skies by scattering green light, retired Environment Canada meteorologist Dan Kulak said in an email. Under specific circumstances, light at sunrise and sunset can get scattered in just the right way to create a green flash, Florian said. At sunset, there’s so much air in the way that the blue is scattered too much for us to see, leaving only the longer-wavelength red light and a red sunset.Įarth’s sky does turn green sometimes. ![]() As you look away from the sun, the amount of air increases, and you get more scattering and blueness. The sky near the sun looks white because there’s not enough air between you and it to scatter the blue out of the light. ![]() Earth’s atmosphere is mostly nitrogen, which is just the right size to scatter the blue wavelengths of light. The sky looks blue during the day because of Rayleigh scattering, explained Frank Florian, senior manager of planetarium and space science at the Telus World of Science in Edmonton. When we look at grass and see green, we are seeing green light reflecting off it - the plant’s chlorophyll absorbs the rest of the colours to produce energy through photosynthesis. Sunlight is a mix of red, green, and blue light, explained Erik Rosolowsky, an astrophysicist at the University of Alberta who has previously pondered the question of green versus blue skies. Science says the answer to both her questions is, “Yes, sometimes.” 'Sometimes'? Albert, “I wonder if the sky is green and the grass is blue?” Įarth generally has green grass and blue skies, observation suggests.īut does it really? And what if it didn’t?Įmily Beaumont of Four Winds Public may have had these questions in mind when she asked Scientific St. The company has several projects in the pipeline, including more Funke adaptations and live-action features.The Gazette is using science to answer questions from students of all ages about the world around them. Gesa and Volker Engel will set up shop with Uncharted Territory in Nuremberg and run the German office with producer Scharbatke, formerly of Kaamos Film. The company has recently worked on such projects as Independence Day: Resurgence (2016) and White House Down (2012), as well as the Emmy-winning mini-series The Triangle (2005). The project will see Volker and Gesa Engel re-locate to Germany with their production company Uncharted Territory, which Engel and partner Marc Weigert set up in Los Angeles in 1999 after the success of Independence Day. When her brother accidentally magics their parents into pigs, and their castle is besieged by the knight Rowan Heartless and his master, Osmond the Greedy, it’s up to Igraine to save the family, even if it means confronting giants and three-headed dragons. Igraine The Brave is the story of the eponymous Igraine, a 12-year-old girl from a family of wizards who doesn’t care for magic, but wants to become a knight. Rise handled some of the 3D animation in the recent Funke adaptation Dragon Rider, which Constantin Film produced. Jane Ainscough has adapted Funke’s novel for the screen, with a score from Grammy-winner Alexander Geringas. Cineworld Now Expects to Emerge From Bankruptcy in JulyĪndreas Deja, a supervising animator on The Lion King, Aladdin, and Beauty and the Beast, will serve as animation consultant for the production. ![]()
