Astronomy Photographer of the Year 2021Winners of the Astronomy Photographer of the Year 2021 competition have just been announced. The annual astronomy photography competition, now in its 13th year, is hosted by the Royal Observatory Greenwich and drew more than 4,500 entries, including many featuring images of distant galaxies that require the use of powerful telescopes.The overall winner of the Astronomy Photographer of the Year 2021 was Shuchang Dong who took this deceptively simple photo of a solar eclipse titled "The Golden Ring" shown above. Dong took the photo in the Ali region of Tibet on June 21, 2020."This place has year-round sunny weather, but in front of the annular eclipse, I saw dark clouds all over the sky," Dong said, "We were waiting with anxious minds but we were lucky. Within a minute of the annular eclipse, the sunshine penetrated through the clouds and afterwards the Sun was sucked into the thick clouds.""This image demonstrates both the beauty and simplicity of an eclipse, but also the science behind this astronomical event," noted competition judge Emily Drabek-Maunder, "Our sun can still be seen as a ring circling the Moon as it passes in front of the Sun, and mountains on the lunar surface can be seen hiding some of this light on the lower righthand portion of the image. This is a stunning achievement!"View more of the fantastic photos of the Astronomy Photographer of the Year competition below.#astronomy #photography #AstronomyPhotographeroftheYear #ShuchangDong #sun #solareclipse

3D Printing an Entire RocketDerek Muller (AKA YouTuber Veritasium) visited a private aerospace startup company called Relativity Space that is 3D printing an entire orbital rocket, including fuel tanks and rocket engines, in just 60 days.To achieve this gargantuan task, Relativity Space built the world's largest metal 3D printer. But why use 3D printing in the first place?According to the company, 3D printed rockets have 100 times fewer parts, 10 times faster production time with no fixed tooling necessary.The 3D printing process sure looks awesome! Take a look at the full clip below:

SpaceX Starship Stacked to Become the World's Tallest RocketSpaceX's Starship is now the world's tallest rocket.Yesterday, on August 6, 2021, SpaceX stacked its Starship SN20 spacecraft on top of the Super Heavy rocket called Booster 4. At 120 m (395 feet) tall, the fully stacked rocket is the tallest in the world. It's actually even taller if you consider the launch pad (145 m or 475 feet).  Stacking the spacecraft is part of the preparation for an upcoming orbital test flight.The previous record was NASA's Saturn V rocket at 111 m (363 feet).To let the world know, SpaceX CEO Elon Musk tweeted "Starship Fully Stacked" along with four images of the stacking process.#Starship #StarshipSN20 #rocket #SpaceX #ElonMusk #SuperHeavyRocket

Elon Musk Shared Pics of The Super Heavy Rocket Being Moved to the Orbital Launch PadThat is a LOT of rocket engines!Earlier this week, Elon Musk shared some photo of the SpaceX Super Heavy rocket on its way to a launch pad in Texas. "Moving rocket to orbital launch pad," Musk tweeted, along with three photos of the massive rocket being hoisted by a crane.The Super Heavy Rocket features 29 Raptor engines, which are powered by liquid methane and liquid oxygen. Each engine is capable of delivering more than half a million pound of force.#ElonMusk #rocket #SpaceX #SuperHeavyRocket #RaptorEngine #rocketengine

Richard Branson Became the First Billionaire in SpaceVirgin Galactic founder Richard Branson has just become the first billionaire in space as his supersonic SpaceShipTwo, a winged airplane with a single rocket motor, flew into suborbital space."To all you kids out there — I was once a child with a dream, looking up to the stars. Now I'm an adult in a spaceship...If we can do this, just imagine what you can do," Branson said in a tweet.#space #VirginGalactic #RichardBranson #rocket #worldrecord #billionaire

Tank Kills a Tank Killer Missile With Its Own RocketWatch this Russian tank defeats an anti-tank rocket-propelled grenade with an active protection system (APS) called "Arena."Popular Mechanics explained how it works:A tank or other armored vehicle is ringed with several millimeter-wave radars, each pointed outward and assigned a different arc of sky. If the radars pick up an incoming rocket or missile, they track the target and determine if it’s on a collision course with the vehicle. If it is, the APS automatically launches an interceptor munition that pops out of an armored silo located on the tank and terminates the threat.So the tank kills anti-tank killer rocket with its own anti- anti-tank killer rocket, got it?Image: First Channel/YouTube#tank #missile #weapon #grenade #rocket

SpaceX Falcon 9 Rocket Blowing Smoke RingsHere's a pic of the SpaceX Falcon 9 rocket lifting off from Space Launch Complex 4 at Vandenberg Air Force Base in California on November 21, 2020. The rocket was carrying Sentinel-6 Michael Freilich spacecraft, which will monitor the Earth's oceans.Just look at those vortex rings!Image: SpaceX - via NASA#NASA #rocket #SpaceX #smokeringThe full image:

Doctor Strange-Style Spiral in the Sky Over the Pacific is Fuel Released by China's Long March RocketOn June 8, 2021, a strange spiral appeared in the skies over the south Pacific islands of New Caledonia and Vanuatu.The greenish spiral, which people noted looked straight out of Marvel's Doctor Strange movie, turned out to be fuel released by China's Long March rocket.From L'Association Calédonienne d'Astronomie Facebook page:Jonathan McDowell, an American astronomer who lists all maneuvers and orbital launches on the planet, has confirmed it was the second floor of a Chinese Long March 2 C rocket, which took off June 18 at 06 h25 UTC from Xichang launch center, with 4 satellites on board.Video: Niels Dumas de Tontouta#rocket #spiral #DoctorStrange #LongMarchRocket
