Tea Behavior in Microgravity Tea behavior in microgravity was observed with sound in a recent experiment. Researchers studied how tea particles move when brewed in a weightless environment. The video captured the unique way the tea leaves dispersed and interacted with hot water without the influence of gravity. This experiment provides valuable insights into fluid dynamics and particle behavior in space, which can have implications for various industries, including food and beverage production. Understanding how liquids behave in microgravity is crucial for developing technologies for future space missions and improving processes on Earth.

Powerful X1.1 Solar Flare Detected Near Sun's Western Edge Around 8:00 a.m., a powerful X1.1 solar flare erupted near the western edge of the Sun's disk. This location indicates that any resulting ejection is unlikely to be directed towards Earth. The short and impulsive nature of the flare suggests that no ejection likely occurred. Earlier, weaker M-class flares from a different active region were observed, with ejections towards Earth, hinting at potential northern lights in the upcoming nights. Now, the next step is to locate areas with clear weather to witness this phenomenon.

Leonids Meteor Shower: Spectacular Celestial Event The Leonids meteor shower originates from a radiant point in the Leo constellation and takes place annually from November 14 to 21. These meteors are linked to the 33-year cycle of comet 55P/Tempel-Tuttle, known for producing the fastest meteors entering the atmosphere at a speed of 72 km/s. The shower's intensity varies each year based on Earth's passage through the density of the comet's trail. The Leonids are renowned for their periodic intense meteor storms, occurring roughly every 33 years. The significant meteor storm in November 1833, witnessed in the United States with an astonishing rate exceeding 200,000 meteors per hour, revolutionized the field of meteor astronomy. Prior to this event, meteors were perceived as atmospheric rather than astronomical occurrences. Another notable meteor storm took place in 1966 due to the comet's 1899 passage, with expectations of another powerful meteor storm in 2066.

30 years of solar activity observed by the SOHO mission 30 years of solar activity were recently celebrated by the SOHO mission, which captures images in the extreme ultraviolet range. The Sun's brightness indicates its activity level, with peak periods causing magnetic field line distortions, increased brightness in extreme ultraviolet, and the release of charged particles into space. SOHO, despite being overshadowed by the Hubble Space Telescope, is a vital space observatory. While Hubble has undergone multiple servicing missions, SOHO managed to survive a month-long communication loss with Earth and the failure of all its gyroscopes, with engineers devising innovative methods to sustain its operations. Surprisingly, SOHO also excelled as a comet hunter, discovering over 5000 comets, a feat unforeseen by its original designers and contributing significantly to comet research.

Three hundredth orbital launch worldwide in 2025 In total, there have been 301 orbital launches in 2025, including today's launches of the Falcon 9 and "Changzheng-12" rockets. Six of these launches were emergency missions. The high number of launches this year is primarily driven by the deployment of low Earth orbit satellite constellations. Approximately two dozen more launches are anticipated before the year concludes.

Jupiter's Aurora Shines in Ultraviolet Light ✨ Jupiter's aurora, visible in the ultraviolet range, outshines Earth's auroras by approximately 1000 times. The vibrant glow is the result of rapid-charged particles interacting with Jupiter's massive magnetic field. Due to the planet's robust magnetic shield and high energy levels, the aurora extends over vast regions near the poles, distinguishing it as one of the most brilliant phenomena in our Solar System.

Iss-73 Crew's Achievements During 245 Days in Orbit Sergey Ryzhikov, Alexey Zubritsky, and Jonathan Kim concluded their 245-day mission aboard the International Space Station by returning to Earth on December 9. In the course of the ISS-73 expedition, the crew executed a series of tasks including two spacewalks by Ryzhikov and Zubritsky as part of the Russian program, alongside another spacewalk undertaken by American astronauts in May. Additionally, the station's orbit was adjusted 11 times during their mission. The crew's responsibilities involved welcoming three manned and six cargo ships to the "space home." At its peak capacity on December 1, eight ships were simultaneously docked to the station for the first time. Throughout their stay, they dedicated time to conducting scientific experiments, maintaining onboard systems, and processing delivered samples.

Giant Squid Nebula Discovered in Bat Nebula The Giant Squid Nebula has been identified within the vast expanse of the Bat Nebula. This remarkable discovery sheds new light on the intricate beauty and complexity of our universe.

Study by Sechenov University: How Cartilage Tissue Changes in Zero Gravity The experiment with the bioreactor "MSK-2" concluded a six-year orbital program. 3D cell spheroids, forming cartilage, were placed in a special setup onboard the station for several weeks and returned to Earth on December 9th. Scientists are now analyzing how microgravity affects the structure of cartilage and its metabolism. Since 2019, 11 series of bio-samples have been sent into space—ranging from stem cells to three-dimensional tissues.
