What is gravitational force ?

Gravitationl force is an attraction force between any two substances, objects, particles present. Gravitational force is not only the force of attraction between Earth and Object, but it exists between the objects present in the universe.The higher the mass of any object, its gravitational force will also be higher.The mass of the lost Earth is greater than the human, hence the force of the Earth's gravitational force is much more than the human gravitational force, when we jump in the air then we come back to the Earth . Theory of gravity , Isaac Newton on the basis of his fundamental findings pointed out that not only the earth, but every particle in the world keeps attracting other particles. The attraction force working between the two particles is inversely proportional to the product of the mass of the particles and the inverse sequence of the square of the distance between them. The gravitational force is called the gravitational force of the mutual attraction acting between the particles and the force generated from it. Newton's law of gravitation is the law of gravity. This rule is also called inverse square law of the inverse square rule of gravity.Newton had told in his theory (Theory of Gravity), the gravitational force of the Sun is more than all Planets of the Solar System.Due to the Sun's gravitational force, all Planets circled the Sun. In 1915 , it is described by Albert Einstein, who describes as a result of the spacetime cascade due to the uneven distribution of the mass, not as a force of gravity. The most extreme example of this curvature of spacetime is a black hole, none of which - not even light - the event of the black hole can survive once before the horizon. For most applications, gravity has been well-guessed by Newton's universal gravitational rule, which describes gravity as a force, due to which any two objects are attracted to each other, with force In proportion to their mass and inversion. The distance between them is proportional to the class. The first example of gravitation in the Universe, probably in the form of quantum gravity, supergravity or a gravitational singularity, with simple space and time, during the Planck era (10 seconds 43 seconds after the birth of the universe), possibly in an unknown situation, From a prevailing condition, such as a false vacuum, quantum vacuum or virtual particle.

NASA/ESA Hubble Space Telescope Reveals New Details of the Orion Nebula’s Star Formation.

This NASA/ESA Hubble Space Telescope image captures the Orion Nebula (Messier 42, M42), the nearest star-forming region to Earth, located about 1,500 light-years away. A captivating new image captured by the NASA/ESA Hubble Space Telescope offers an extraordinary look into the Orion Nebula, the nearest massive star-forming region to Earth. Located just 1,500 light-years away, this nebula is visible to the naked eye below the three stars forming Orion's "belt." The region is home to hundreds of newborn stars, including two protostars featured in the image: HOPS 150 and HOPS 153. Named after the Herschel Orion Protostar Survey, conducted with ESA’s Herschel Space Observatory, the protostars HOPS 150 and HOPS 153 provide key insights into the early stages of star formation. HOPS 150, visible in the upper-right corner of the image, is a binary star system, with two young stars orbiting one another. These protostars are surrounded by small dusty disks, where material from th...

New Method Detects Small Asteroids in Main Belt, Offering Insight for Planetary Defense.

An international team of physicists, led by MIT researchers, has developed a groundbreaking method to detect small asteroids, as small as 10 meters in diameter, within the main asteroid belt. These space rocks, ranging from the size of a bus to several stadiums wide, were previously undetectable using traditional methods. The team's discovery, detailed in a paper published in Nature, could significantly improve tracking of potential asteroid impactors, aiding planetary defense efforts. The main asteroid belt, located between Mars and Jupiter, is home to millions of asteroids, but until now, scientists could only detect objects roughly a kilometer in diameter. The new detection technique, which utilizes the "shift and stack" method, is able to identify much smaller asteroids, even those far from Earth, enabling more precise orbital tracking. This breakthrough is crucial for planetary defense, allowing scientists to spot near-Earth objects that may pose a threat in the fu...

XSPECT Payload Successfully Validates Performance through Cas A Observation.

The XSPECT instrument captures a detailed spectrum of the supernova remnant Cassiopeia A (Cas A), encompassing both the Galactic Cosmic Ray (GCR) background and the Cosmic X-ray Background (CXB). The flux observed above 8 keV predominantly results from the combined contributions of CXB and GCR. The presented spectrum, depicted in the figure, is derived from a cumulative integration time of 20 ksec, collected across multiple orbits, providing valuable insights into the X-ray emissions associated with Cas A. XPoSat, India's inaugural X-ray polarimetric mission, has achieved a significant as the XSPECT instrument captures its initial observations from the Cassiopeia A (Cas A) supernova remnant. Launched on January 1, 2024, XPoSat is equipped with two co-aligned instruments, namely the POLarimeter Instrument in X-rays (POLIX) and X-ray SPECtroscopy and Timing (XSPECT). This mission is designed to unravel the mysteries of cosmic X-ray sources. While POLIX focuses on examining X-ray po...
