   In a groundbreaking discovery, scientists have finally pinpointed the  origin of the asteroid  that wiped out the  dinosaurs 66 million years ago . This catastrophic event led to the mass extinction of  70% of Earth's species  and has long puzzled researchers. However, a new study published in  Science  reveals that this deadly asteroid was  not a comet , as previously speculated, but a  rare C-type asteroid  formed beyond  Jupiter's orbit . Credit:- AI Imagination Asteroid's Origin:  The study's lead author, Mario Fischer-Godde, a geochemist from the University of Cologne, used advanced techniques to analyze ruthenium isotopes in sediment samples. These isotopes, which match those in asteroids beyond Jupiter, indicate that the Chicxulub impactor originated from this distant region. Debunking the Comet Theory:  Previous theories suggested a comet might have caused the mass extinction. However, the new findings...

🚀 A Leap in Planetary Defense 🚀 Thirty years ago, the cosmic ballet of Shoemaker-Levy 9 colliding with Jupiter captivated astronomers and sparked a crucial question: "Can we prevent such a catastrophe from striking Earth?" Fast forward to today, and the European Space Agency (ESA) is taking monumental strides in planetary defense by announcing its 2029 mission to asteroid Apophis —aptly named Ramses . ESA's planned Ramses mission would arrive at the asteroid Apophis two months before the asteroid's April 2029 close flyby of Earth.  Credit:  ESA 🌌 Mission Ramses: Safeguarding Earth 🌌 The Rapid Apophis Mission for Space Safety (Ramses) is set to rendezvous with the 99942 Apophis asteroid, a celestial giant roughly the size of a cruise liner. As Apophis makes its exceptionally close approach to Earth on April 13, 2029, passing within 32,000 km, Ramses will monitor its every move. This mission aims to understand how Earth's gravity will alter the asteroid's...

  In a thrilling turn of events, the spacecraft formerly OSIRIS-REx was rebranded as OSIRIS-APEX and set on an unprecedented mission to explore the enigmatic asteroid Apophis . Name taken from the ancient Egyptian god of darkness , this asteroid's upcoming flyby of Earth in 2029 promises to be a monumental event unseen since recorded history began. OSIRIS-APEX: A New Mission Unfolds After a successful seven-year, four billion-mile journey collecting samples from asteroid Bennu, OSIRIS-REx's mission was extended . With its instruments in top condition and plenty of fuel left, NASA decided to repurpose the spacecraft for a new mission: exploring Apophis. This decision marks a significant progression in the spacecraft's journey as it transitions from Bennu's carbon-rich terrain to Apophis, an S-type asteroid composed of silicate materials and nickel-iron. Apophis: An Unprecedented Close Encounter Approximately 367 yards (340 meters) across Apophis will pass within 20,0...

  In a significant announcement, ISRO Chairman S. Somnath revealed that ISRO ( the Indian Space Research Organisation ) is gearing up for a groundbreaking study of the Apophis asteroid when it makes its closest approach to Earth in 2029 . This ambitious mission will see ISRO joining forces with leading space agencies such as NASA , JAXA , and ESA , highlighting India's growing prowess in space exploration. The Apophis Study: A Global Endeavor The 340-meter-wide Apophis asteroid, named after the ancient Egyptian god of chaos, will come alarmingly close to Earth in 2029. This rare event has spurred a global effort to study the asteroid and develop strategies for planetary defense. ISRO's collaboration with international partners underscores the importance of a united approach to tackle potential cosmic threats. A Dire Warning from ISRO Chief In a recent interview, S. Somnath discussed the real possibility of an asteroid impact on Earth. He emphasized the need for preparednes...
