Three New Pulsars Discovered in Ancient Galactic Dance🌌

 In a celestial discovery that's music to astronomers' ears, China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) has tuned into the rhythmic pulse of Messier 15, an old Galactic globular cluster residing 35,700 light years away. The cosmic symphony reveals three new pulsars, adding fascinating notes to the stellar composition.

  • Pulsars, those highly magnetized, rotating neutron stars emitting electromagnetic radiation, are no strangers to Messier 15. Yet, FAST has uncovered a trio that steals the spotlight this time. Two boast leisurely spins, earning the title of long-period pulsars, while the third dazzles as a millisecond pulsar, whirling with rapid intensity.
  • The standout, PSR J2129+1210J, commands attention as an isolated millisecond pulsar, showcasing a mesmerizing spin period of 11.84 milliseconds. Meanwhile, its companions, PSR J2129+1210K and PSR J2129+1210L reveal their distinctive long-period rhythms, marking an extraordinary celestial dance within the ancient confines of Messier 15.

  • Messier 15, a core-collapsed Galactic globular cluster, holds prestigious status as one of our galaxy's oldest and most metal-poor gems. Laden, with a mass of 560,000 solar masses and boasting an age of about 12 billion years, became the stage for this pulsar spectacle. Previous observations hinted at an affluent pulsar population, and FAST's latest performance confirms this hypothesis.

While the exact positions of PSR J2129+1210K and PSR J2129+1210L remain a mystery, astronomers anticipate that they swirl not too far from the heart of Messier 15. Further observations are on the cosmic agenda, aiming to pinpoint their location and unveil the secrets behind their celestial choreography. Are they the echoes of a stellar youth or the reincarnation of recycled pulsars? The answers lie in the next act of this cosmic saga.

"NASA's Artemis Mission Faces Delays, Prioritizing Safety Above All" 🛰🌕🌌

Image
"The Artemis 2 Lunar Fly-By Now Set for September 2025, Moon Landing Pushed to September 2026" NASA, a pioneer in space exploration, announced on Tuesday that its Artemis mission is experiencing delays due to safety concerns. Initially slated for November 2024, the Artemis 2 lunar fly-by is now scheduled for liftoff in September 2025, with the Artemis 3 Moon landing pushed to September 2026. NASA Administrator Bill Nelson underscored that prioritizing safety is paramount, and the choice to postpone launch dates was taken to guarantee a safe and successful mission. The setbacks are attributed to various factors, including spacesuit development and the need for SpaceX's Starship to be tested before its involvement in the mission. Amit Kshatriya, Deputy Associate Administrator for NASA's Moon to Mars Program, highlighted challenges such as unexpected issues with the Artemis 1 test flight's heat shield and identified flaws in the design of the Artemis 3 Orion craft

🌌 NASA on High Alert! Massive 500-ft Space Rock (Asteroid 2023 VD6) on Collision Course with Earth at Mind-Boggling Speed! 🚀💥

Image
  The cosmos is staging a celestial drama as NASA sounds the alarm bells, tracking a colossal asteroid hurtling towards Earth at an astonishing 55,680 km/h. Brace yourselves as we delve into the details of this humongous space rock, Asteroid 2023 VD6, and unravel the cosmic dance unfolding in the vast expanse of our solar system. Asteroid 2023 VD6: A Gargantuan Visitor 🌠 This mammoth, building-sized celestial body, part of the Apollo group, is making a close encounter with Earth today, December 23, 2023, at a mere 2.53 million miles away. Zooming through space at breakneck speed, it completes an orbit around the Sun in just 1,378 days. 🚀 Details about its trajectory reveal a gripping narrative—its aphelion at a staggering 610 million kilometers and perihelion at 115 million kilometers. According to experts at the-sky.org, please mark your calendars for another rendezvous on May 03, 2039, when it will come within 9.83 million kilometers of our planet.

Could there be a black hole inside the sun 🌞?

Image
 Imagine our sun, the source of life, collapsing into a black hole or devoured by a wandering cosmic wanderer. Brace yourselves – the end might be closer than we think! If a massive black hole swallowed our sun, we'd have a mere eight minutes before everything changed. But what if it's a small primordial black hole? Now, that's a twist worth exploring. Primordial black holes, born in the universe's infancy, are hypothetical entities, smaller than a baseball and as massive as an asteroid. They play a role in theoretical models explaining mysteries from dark matter to the enigmatic Planet X. Enter Hawking stars – stars with a black hole at their core. New research delves into the consequences of a sun-like star capturing a primordial black hole. Initially harmless due to its minuscule mass, it could reshape the star's fate and lead to its demise over time. The study emphasizes that the outcome depends on the primordial black hole's initial size. If it falls within
