The Orion Nebula , a celestial marvel, captivates stargazers worldwide with its ethereal beauty. Yet, amidst its grandeur lies a tale of cosmic tragedy unfolding for a young star and its dreams of planetary formation. In a recent revelation, data from the James Webb Space Telescope (JWST) and the Atacama Large Millimeter-submillimeter Array (ALMA) has uncovered a sobering reality - the protoplanetary disk, dubbed d203-506, orbiting a small red dwarf in the Orion Nebula, is facing a brutal fate. Initially destined for the birth of planets, this disk is being relentlessly vaporized by intense bursts of far-ultraviolet (FUV) radiation emitted by its massive neighboring stars. Olivier Berne, an astrophysicist leading the study, elucidates that the relentless FUV radiation fields excite the gas particles within the disk, propelling them to escape velocity and dispersing into the vastness of the interstellar medium. Each year, the disk loses an Earth-mass worth of material, jeopardizing its ...

 India's space exploration endeavors are poised to reach new heights with the imminent debut of ISRO 's groundbreaking reusable launch vehicle, Pushpak . This innovative project, which has been in development since 2012 under the code RLV (Reusable Launch Vehicle) , is set to redefine the nation's capabilities in accessing space. Pushpak represents a paradigm shift in space launch technology as a fully reusable, single-stage-to-orbit (SSTO) rocket. Unlike traditional launch vehicles, Pushpak is designed to launch vertically, with boosters aiding its ascent. Once in orbit, it will autonomously deploy satellites before returning to Earth, landing horizontally on an airstrip akin to an airplane. Significant milestones have marked the journey toward Pushpak's realization. In 2016, the "Hypersonic Flight Experiment (HEX)" showcased its potential, reaching a maximum altitude of 65 km and lasting 770 seconds. Subsequent tests, including the recent "Landing Exper...

Following India's Chandrayaan mission, all eyes are now set on the moon, with Russia and China joining forces. Despite setbacks, Russian and Chinese space agencies have announced plans to collaborate on building a shared nuclear reactor on the moon, set to be deployed by 2035 , without human intervention. Russia's space agency, Roscosmos, has revealed a collaborative effort with China to establish an automated nuclear reactor on the lunar surface by 2035. Both nations will operate This proposed reactor jointly to power a proposed lunar base. In 2021, Roscosmos and the China National Space Administration (CNSA) unveiled intentions to construct a shared moon base named the International Lunar Research Station (ILRS). However, due to strained relations with CNSA and Roscosmos exiting the International Space Station by 2025, NASA astronauts are unlikely to visit this base. On Tuesday (March 5), Roscosmos announced plans to develop a nuclear reactor in collaboration with CNSA to p...

ISRO (Indian Space Research Organisation) has set the stage for an epic chapter in India's space exploration journey by unveiling four valiant astronauts for the highly anticipated Gaganyaan mission ! 🌟 In a noteworthy collaboration with the Indian Air Force , ISRO proudly presents the elite team of astronauts who will embark on a groundbreaking mission to propel India into the cosmos. 🌌 Selected from the cream of the crop, these four astronauts, fondly known as Vyomnauts , are set to etch their names in history. Meet the fearless pioneers who will represent India in the vast expanse of space: Group Captain Prashanth Balakrishnan Nair , Group Captain Ajit Krishnan , Group Captain Angad Pratap , and Wing Commander Shubhanshu Shukla . 💫 Under the visionary leadership of Group Captain Prashanth Balakrishnan Nair, the Gaganyaan mission aims to catapult three Indian astronauts into orbit, where they will orbit at a staggering 400 km altitude for three days before safely returning ...
