  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...

 The NASA/ESA Hubble Space Telescope has once again dazzled the world with its latest image, capturing the stunning transformation of a nebula by infant stars. This captivating image presents RCW 7, a nebula located just over 5,300 light-years away in the constellation Puppis. This striking NASA/ESA Hubble Space Telescope image features the nebula RCW 7. ESA/Hubble & NASA, J. Tan (Chalmers University & University of Virginia), R. Fedriani Nebulae, rich with the raw materials needed for star formation, are where the magic begins. Under gravity’s influence, parts of these molecular clouds collapse and coalesce into very young stars, known as protostars. These protostars, still enveloped in spinning discs of leftover gas and dust, are massive and emit strongly ionizing radiation and stellar winds. This powerful radiation transforms the nebula into an H II region, filled with hydrogen ions that emit a soft pinkish glow. The image, taken with Hubble’s Wide Field Camera 3 i...

 Auroras (the northern and southern lights) are visible from the ground after powerful solar storms, but these natural light shows look even more majestic from above. Here are 24 spectacular photos of auroras taken from space. 1. View of the Southern Lights from Challenger  A green aurora slices through the Southern Hemisphere between Antarctica and Australia. This vintage shot of the southern lights was captured in April 1985 by astronaut Robert F. Overmyer aboard the space shuttle Challenger. (Image credit: NASA / Robert F. Overmyer) 2. Aurora over Moscow The northern lights swoop beneath a full moon as Moscow glows like a golden spider on the left of the frame. This photo was taken in April 2014 by an Expedition 39 crewmember aboard the International Space Station (ISS). (Image credit: NASA / Rick Mastracchio) 3. A World-Eating Serpent A vivid-green, nearly round aurora curls over the Southern Hemisphere like an enormous serpent. This exquisite photo was taken with NASA's I...
