SpaceTime Series 27 Episode 126 *NASA's Parker Solar Probe Completes 21st Philip of the Sun NASA's Parker Solar Probe has achieved its 21st close encounter with the Sun, matching its previous distance and speed records. The spacecraft swooped to within 7.26 million kilometers of the solar surface at a record speed of 635,300 km/h. This flyby sets up the probe for its final closest approaches, with its orbit shaped by a Venus gravity assist. The mission, launched in 2018, aims to study the Sun's corona and the solar wind, unraveling the mysteries of solar phenomena that impact the solar system. *Webb Space Telescope Finds Potential Missing Link to First Stars Astronomers using NASA's Webb Space Telescope have identified a galaxy with an unusual light signature that could be a missing link in galactic evolution. The galaxy, found approximately a billion years after the Big Bang, features gas outshining its stars, possibly due to massive, hot stars. This discovery offers insights into the transition from the universe's first stars to more familiar galaxies, providing a glimpse into the early cosmic environment. *Perseverance Rover's Key Science Instrument Robert NASA's Perseverance rover on Mars has regained the use of its critical Sherlock instrument after a six-month effort. The spectroscope, crucial for detecting organics and assessing habitability, had malfunctioned in January. The successful repair allows the rover to continue its mission of analyzing Martian rocks and soil for signs of past life and understanding the planet's geological history. The Science Robert A new study suggests that caffeine consumption may improve heart health by aiding vascular growth. Another study reveals increasing plant cover in Antarctica, linked to climate change. Research highlights how people often form opinions without sufficient information, contributing to conflicts. Lastly, a study confirms that astrologers perform no better than chance in predicting character or future events. 00:00:00 - This is spacetime series 27, episode 126, for broadcast on 18 October 2024 00:00:30 - NASA's Parker solar probe completes 21st close encounter with the sun 00:03:08 - The Parker solar probe is touching the sun for the first time 00:08:32 - Galaxy with unusual light signature attributed to gas outshining stars 00:12:00 - NASA scientists have successfully brought a key science instrument back online on Mars 00:14:51 - A new study has shown that consuming more caffeine may improve your heart health 00:17:01 - New study shows people are biased to assume they know enough about situations www.spacetimewithstuartgary.com www.bitesz.com 🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn.

"In a new study published in The Astrophysical Journal, a researcher from The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, explores critical aspects of a phenomenon called kinetic Alfvén waves (KAWs) to provide fresh insights into an age-old heliophysics mystery.

Syed Ayaz, a graduate research assistant at the UAH Center for Space Plasma and Aeronomic Research (CSPAR), examined the potentially pivotal role of KAWs in heating the solar corona, moving science one step closer to solving the puzzle of why the corona is many times hotter than the surface of the sun itself.

"For decades, Alfvén waves have been proven to be the best candidates for transporting energy from one place to another," Ayaz says, noting the potential role of KAWs in driving coronal heat.

"This paper utilizes a novel approach to model energetic particles in space plasmas, as observed by satellites like Viking and Freja, to answer how the electromagnetic energy of the waves, interacting with particles, transforms into heat during the damping process as the waves move through space."

"The corona, or solar atmosphere, is an enigmatic region surrounding our home star that extends far beyond the visible disk of the sun, stretching some 8 million kilometers above the sun's surface. Yet, the corona is also characterized by extraordinarily high temperatures, a mystery that has captivated astrophysicists for nearly seventy years."

brightness not very indicative of what it was like irl until i kind of messed with it at the end

that was absolutely incredible. There are no words, really. Everything about today was perfect and exactly what I always dreamed of. seeing a total solar eclipse was a long time bucket list item for me and it was literally jaw-dropping. my hands were shaking filming here

also dont give me shit for not showing the sun i was too busy looking at it with my eyes & not through my camera (also it looks bad on camera)

the crowd was something to behold alone. i really wasnt sure what to expect when i went over to Old Port but wow, the turnout was insane

The famous Eiffel Tower in Paris, France is pictured on the left lit up in gold at night. A blue laser shines out from the top. Clouds dot the background sky. The Moon is also visible through the clouds, but is circled by colorful rings: a lunar corona.

Explanation: Why does a cloudy moon sometimes appear colorful? The effect, called a lunar corona, is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar coronae are one of the few quantum mechanical color effects that can be easily seen with the unaided eye. Solar coronae are also sometimes evident. The featured image was taken last month from Paris, France. The blue beacon emanating from the Eiffel Tower did not affect the colorful lunar corona.
