  "Celestial Spectacle: Comet '12P/Pons-Brooks' to Grace Mumbai Skies After 71 Y ears" Mumbai, a bustling metropolis that rarely pauses for a celestial spectacle, is set to witness the return of a long-lost visitor to our night skies. Named '12P/Pons-Brooks,' this periodical comet is creating ripples of excitement among the international scientific community as it hurtles toward Earth on its return journey after 71 years. The astronomical community in India has already been treated to early glimpses of this celestial wanderer, with amateur astronomers capturing its bright, tiny spot on camera. Dr. Bharat Adur, a prominent scientist and the founder-secretary of the Amateur Astronomers Association (Mumbai), shared the exhilarating news of the comet's imminent visit. Astronomers from various parts of India, including a passionate amateur from Jorhat, Assam, have managed to capture the comet's early appearance. A captivating photo of '12P/Pons-Brooks...

James Webb discovers black hole existence at start of the universe, study shows

  James Webb discovers black hole existence at start of the universe, study shows The mysterious origins of the universe have long posed a cosmic puzzle, akin to a chicken-and-egg dilemma. Did the celestial dance begin with the formation of stars and galaxies, gradually giving rise to black holes? Alternatively, did black holes exist before the inaugural galaxies made their cosmic debut? As the primordial matter cooled and coalesced after the Big Bang, it unfolded into the structures and entities that shaped the universe over its extensive 13.8 billion year history. These entities, observed today as stars within gravitational bound systems called galaxies, orbit a central supermassive black hole. According to conventional wisdom, stars and galaxies dominate this cosmic narrative. However, a recent review of early universe data collected by the James Webb Space Telescope suggests a paradigm shift. This suggests that black holes and galaxies did not follow a sequential order but emer...

Laser Instrument on NASA’s LRO Successfully ‘Pings’ Indian Moon Lander

Laser Instrument on NASA’s LRO Successfully ‘Pings’ Indian Moon Lander   In a significant breakthrough, NASA achieved the transmission and reflection of a laser beam between its Lunar Reconnaissance Orbiter (LRO) and a small retroreflector on ISRO's Vikram lander on the lunar surface. This successful experiment, conducted near the moon's south pole, introduces a new method for precisely locating targets on the lunar surface. On December 12, 2023, at 3 p.m. EST, the LRO pointed its laser altimeter instrument toward Vikram, which was approximately 62 miles away near the Manzinus crater. After LRO transmitted laser pulses toward Vikram, the orbiter registered light bouncing back from a tiny NASA retro reflector aboard Vikram, confirming the success of the experiment. While tracking Earth-orbiting satellites with laser beams from the ground is a common practice, the reverse technique—sending laser pulses from a moving spacecraft to a stationary one to determine its precise loca...

"World on Edge: NASA's Asteroid Alert Dominates Headlines A midst a Tapestry of Global Developments"

  "World on Edge: NASA's Asteroid Alert Dominates Headlines A midst a Tapestry of Global Developments"   On a day marked by a cascade of noteworthy developments, one event has captured the collective attention of the world – NASA's detection of an asteroid hurtling towards Earth. This celestial visitor, approximately the size of an aircraft, is barreling through space at a staggering speed of 30,606 kmph. The revelation stems from NASA's Asteroid Watch dashboard, a cutting-edge tool meticulously designed to track asteroids and comets with close approaches to our planet. The dashboard not only discloses the date of the asteroid's closest approach but also provides crucial details such as its approximate diameter, relative size, and distance from Earth during the encounter. It emphasizes that any object larger than 150 meters, capable of approaching within 4.6 million miles of Earth, is classified as a potentially hazardous object, underscoring the signi...

Moons scientifically important sites may be lost for ever in Mining Rush.

  Moons scientifically important sites may be lost for ever in Mining Rush. Researchers seek protection for pristine areas of moons far side and polar regions. The moon is becoming a potential battleground where scientific exploration collides with commercial interests, as NASA launches its first lunar mission in half a century. Scheduled for later this year, Peregrine Mission 1, created by the private company Astrobotic, ushers in a new era in lunar exploration. Many more missions, including those under NASA's Artemis program, are set to follow, sparking excitement among researchers about a potential golden age of exploration. However, there are concerns that the growth of private landers could trigger a "moon-rush", with companies looking to exploit valuable minerals and resources, potentially compromising scientifically significant lunar sites. Because private entities lack sufficient legal protection for these areas under current space laws, scientists are imm...
