Ancient Interstellar Comet 3I/Atlas
Astronomers have unveiled that the newly discovered interstellar object, 3I/Atlas, could be the oldest comet ever observed, potentially predating our solar system by over 3 billion years. This water-rich visitor, detected by NASA's ATLAS survey, is only the third known object from beyond our solar system to reach us. A study by Matthew Hopkins from Oxford University suggests that 3I/Atlas may be more than 7 billion years old, offering a glimpse into a part of the Milky Way previously unseen. As it approaches the sun, its activity is expected to increase, revealing more about its composition and the role ancient comets play in star and planetary formation.
Unraveling the Mysteries of a Rare Pulsar
In another exciting development, astronomers have made significant strides in understanding a unique pulsar system, PSRJ 1023 0038. This transitional millisecond pulsar, which interacts with a lower mass stellar companion, has been studied using data from NASA's Imaging X-Ray Polarimetry Explorer (IXPE). The findings suggest that the X-ray emissions originate from the pulsar wind rather than the accretion disk, challenging existing models and providing new insights into neutron star behavior and particle acceleration.
Axiom Space AX4 Crew Returns
The Axiom Space AX4 crew has successfully splashed down in the North Pacific Ocean after nearly three weeks aboard the International Space Station. This mission, part of NASA's efforts to promote commercial activities in space, included a diverse crew and numerous scientific experiments. With the return of the AX4 crew, preparations are underway for NASA's upcoming Crew 11 mission, further expanding humanity's presence in low Earth orbit.
