People gathered across the UK to see the biggest and brightest moon of the year. It was a rare chance to gaze at what is known as a blue supermoon, with the last such phenomenon occurring in 2009. The blue moon refers to the second full moon in one calendar month, which happens approximately once every two or three years. This one is also a supermoon when the Earth's natural satellite appears about 14% bigger and 30% brighter in the sky as it reaches its closest point to Earth.

The James Webb Space Telescope has revealed the secrets of Earendel, the farthest star ever discovered in the universe, lying at the edge of time. Earendel is so far away that its light has taken 13 billion years to reach us through a cosmic coincidence of line of sight. But this doesn't mean that it's 13 billion light-years away. The proper distance of this star, which also considers the universe's expansion, is about 28 billion light years. Also, if the Big Bang theory is correct, this means that we are actually looking at a star that existed within the first billion years of the universe. Hence, it could belong to the elusive first generation of stars that astronomers have been hunting for decades. But Earendel is so far away that it's impossible to study its properties in detail with Earth-based telescopes or even the Hubble Space Telescope. And this is where the James Webb Space Telescope comes into the picture. So, how did astronomers discover Earendel, a lone star so far away in the cosmos? How is it different from the stars we observe in the local universe? Finally, and most importantly, why were astronomers surprised by the James Webb Space Telescope observations of Earendel?

When you think of ringed planets, you probably assume there's only one of them in our Solar System, Saturn. But what if I told you that there are three other planets similar to Saturn? It's true. Jupiter, Uranus, and Neptune all have their own sets of rings.

On Oct. 14, 2023, a “ring of fire,” or annular, solar eclipse will travel from Oregon coast to the Gulf of Mexico. Weather permitting, most of the Americas will be able to view at least a partial solar eclipse. Click here to see the NASA 2023 and 2024 Solar Eclipse Map: https://go.nasa.gov/USEclipseMaps An annular solar eclipse occurs when the Moon passes between the Sun and the Earth, but is just far away enough in its orbit that the Sun is not completely covered—creating a large, bright ring in the sky. WARNING: During an annular eclipse, it is never safe to look directly at the Sun without specialized eye protection designed for solar viewing. How to safely view an eclipse: https://solarsystem.nasa.gov/eclipses... Not in the path of the eclipse? Watch with us from anywhere in the world. We will provide live broadcast coverage on Oct. 14 from 11:30 a.m. to 1:15 p.m. EDT (1530-1715 UTC) on NASA TV, NASA.gov, the NASA app, and right here on YouTube: https://youtube.com/live/LlY79zjud-Q Learn more about the upcoming annular solar eclipse: https://solarsystem.nasa.gov/eclipses...

The story of Apollo 13, showcases the remarkable human resilience and determination to survive against overwhelming odds. The mission began in Florida, USA, as three astronauts embarked on an audacious journey to the moon, driven by the success of previous lunar missions. However, their aspirations of moonwalking were abruptly shattered just two days later when a sudden and powerful explosion rocked their spacecraft 210,000 miles away from Earth. The ship's alarms blared, lights flashed, and the astronauts found themselves in a dire situation. Stranded far from home with limited oxygen, they were faced with an unprecedented crisis that demanded their utmost courage and resourcefulness. Did they manage to get back to earth? What was their fate? Find out in this gripping video

Apollo, the project conducted by the U.S. National Aeronautics and Space Administration (NASA) in the 1960s and ’70s landed the first humans on the Moon. All told, 24 Apollo astronauts visited the Moon and 12 of them walked on its surface. Additional NASA astronauts are scheduled to return to the Moon by 2025 as part of the Artemis space program. In May 1961 Pres. John F. Kennedy committed America to landing astronauts on the Moon by 1970. The choice among competing techniques for achieving a Moon landing and return was not resolved until considerable further study. Three methods were considered. In direct ascent, one vehicle would lift off from Earth, land on the Moon, and return. However, the proposed Nova rocket would not be ready by 1970. In Earth orbit rendezvous, a spacecraft carrying the crew would dock in Earth orbit with the propulsion unit that would carry enough fuel to go to the Moon. However, this method required two separate launches... Read more: https://www.britannica.com/science/Apollo-space-program

In an incredible first, astronomers have discovered what lies at the core of Mars. It turns out, the Red Planet isn't as lifeless as we once thought. Mars wasn’t always a dusty, barren world. There’s plenty of evidence that the planet was warm, had lakes of liquid water, and was habitable for a short period in its history. Astronomers had always wanted to know the reason behind this transition, and for that, they had to know what lies at the core of Mars. When the InSight lander started studying the planet’s interior, it discovered that the planet is still rumbling with seismic activity. Now, following a rigorous half-decade mission, InSight has granted scientists a clear vision of the Martian core. So, how does Mars' core differ from Earth's? What methods did InSight employ to unveil the core of the Red Planet? Finally, and most importantly, what does it tell us about the future of our planet?

Recently, SpaceX conducted another static fire test for its Starship booster 9. This event was not just another test; it marked the second time they've tested this since its launch into orbit back in April. Their goal? To prepare for their next big step: a second orbital test flight. What's truly remarkable about this is the speed at which SpaceX is making these advancements. In less than three weeks, they've held two static fire tests. For those unfamiliar with the space industry's usual pace, this kind of rapid progress is quite astonishing. To provide some context, consider SpaceX's main competitor, Blue Origin. Both these companies have a lot in common. Both were founded by tech billionaires: SpaceX by Musk and Blue Origin by Bezos. Blue Origin has been working on its own rocket, the New Glenn, which many believed would rival or even surpass SpaceX's Starship. However, here's where the story takes a twist: despite the Starship being tested multiple times, undergoing numerous launches, and being visibly active, the New Glenn rocket hasn’t made any public test flights. And what's even more surprising? The idea and development of New Glenn started before Starship, showcasing the contrasting speeds at which the two companies operate. For those who've been following the recent developments at starbase facility, you might remember that the first test on august 6 presented unexpected complications. The ignition sequence for the 33 Raptor engines did not go according to plan. A malfunction led to four of these engines shutting down far sooner than anticipated. As a result, what was intended to be a 5-second demonstration was abruptly cut short, clocking in at a mere 2.74 seconds. These unexpected hiccups provided clear indications that SpaceX was grappling with the reliability of its Raptor engines. Fast forward to today, SpaceX's latest static fire test of Booster 9 showcased significant progress. The test achieved a near full duration firing of around 5 seconds before the engines shut down as intended. While SpaceX has not yet confirmed whether all 33 Raptor engines were operational during the test, Musk indicated the static fire's success, suggesting that the company has made strides in addressing previous concerns.

What does it *really* feel like to jump from space? In 2012 Felix Baumgartner took a helium balloon into the stratosphere and skydived back to earth in a specially made space suit. Whilst in freefall he broke the speed of sound and entered a spin which threatened the entire Red Bull Stratos mission... Felix reflects on his achievement and shares what it really felt like to jump from the edge of space.

Spacex Crew 7 Launch LIVE | SpaceX And NASA Launch International Crew On Space Station Mission The launch was scrubbed Friday because NASA says they wanted more time to make sure it is safe, even though everything is fine. Specifically, the team wants to do more analysis on the Dragon capsule's environmental control and life support system. That system provides clean air and water to the crew inside the spacecraft. At the Kennedy Space Center's launch complex 39A, the Dragon Crew Capsule 'Endurance' sits atop its powerful Falcon 9 rocket, ready for a 3:27 a.m. liftoff with the promise to reshape the future of space travel. The NASA SpaceX Crew-7 mission has four astronauts from four different space agencies, a first for the commercial crew program. Commanding is NASA's Jasmin Moghbeli, Danish astronaut Andreas Mogensen of the European Space Agency will serve as a pilot, and mission specialists from their countries’ respective agencies are Russian Konstantin Borisov and Satoshi Furukawa from Japan.

Where are the Moon rocks from the Apollo missions kept? When they’re not being studied by institutions or enjoyed by museumgoers, NASA has a specialized Lunar Sample Curation Laboratory at NASA’s Johnson Space Center to store and keep these otherworldly samples safe. Studying these samples helps us learn more about the origin of not only our moon but our planet. Deputy Apollo Sample Curator (Sept 2019 – Dec 2022) Dr Juliane Gross explains more about lunar sample curation.

Russia’s first moon mission in 47 years failed after its Luna-25 spacecraft smashed into moon on Aug 20. Roskosmos, Russia’s space corporation, said it had lost contact with the craft shortly after a problem occurred. This development came soon after the craft was shunted into pre-landing orbit on Aug 19. An incident occurred, while the spacecraft was trying to enter a pre-landing orbit according to Roscosmos. Interestingly, Russia had not attempted a moon mission since Luna-24 in 1976. Luna-25 was supposed to execute a soft landing on the south pole of the moon on Aug 21, as per Russian space officials. Luna-25 took off from the Vostochny launch facility in Russia’s Far East, the Russia-based TASS news agency reported. Meanwhile, India’s third lunar mission Chandrayaan-3 is on track. Chandrayaan-3 is set to land on the moon on August 23, 2023 (Wednesday). The spacecraft is now just three-day away from its final destination, the moon’s south pole.

The Chandrayaan Landing phase of Decent can be Divided into several stages Stage 1 The Vikram Lander starts its descent from 30 Kilometers Stage 2 At 7.4 km the Thrusters fires up making a rough braking process Stage 2 At this stage, Vikram Lander uses Attitude Hold, This Is the autopilot setting that will hold the pitch of the aircraft constant when set to this mode, at this angle. Stage 3 It is here thrusters initiate the Fine Braking Process, Stage 4 This is the Terminal Descent Phase, it is at this stage it uses all it thrusters to land on the surface of the moon. Stage 5 If the lasers and Cameras detect, an unsuitable landing site it’s programmed to be moved to150 m in search for a planned B Landing Site.
