Voyager 2 reported back from outside the solar system, voyager 2 has reached the interstellar space, interstellar space is called the outer part of tha solar system.voyager 2 is called the second ambassador of humanity, because like voyager 1 it was left to find another civilization.Voyager 2 reported back from the frontiers of the solar system, with the message that the boundary of the Sun's field is a complex and ever-changing place.

 Voyager 2 broke through heliopause last year, what is heliopause? The "bubble" of the heliosphere is continuously inflated" from the plasma arising from the Sun, known as the solar wind, it is a kind of bubble made of plasma.voyager 1 encountered heliopause on 25 August 2012, when voyager 1 measured an increase in plasma density nearly forty times.Heliopause was detected on 5 November 2018 by Voyager 2.Heliopause marks the boundary between matter arising from the Sun and matter arising from the rest of the galaxy.Voyager 2 has overtaken the heliosphere, and reached space.Voyager 1 and 2 These explorers are "taking mankind to new places amazingly, 60 years ago than we ever imagined, says Gary Zank,a space physicist at the University of Alabama at Huntsville.

 The view outside the window of Voyager 2 changed on November 5, 2018, when the craft was about 17.8 billion kilometers from the Sun, 119 times farther than Earth, and densified the surrounding plasma by about 20 times.voyager 2 is now in its extended mission to study the outer reach of the solar system, voyager 2 has a tenure of 42 years, 2 months and 25 days, on 14 November 2019, via voyager 2 from NASA Deep Space Network  Keeps in touch with  Researchers report that voyager 2 has released protective magnetic bubbles from the Sun.Voyager 1 had already reached heliopause, but one advantage of voyager 2 was that it had a working sensor that could measure the speed, and temperature density, of the surrounding plasma. The sensors in voyager 1 stopped long before reaching heliopause, so researchers had to detect many plasma properties from other measurements, which were not as accurate as direct measurements.Voyager 1 and 2 are doing both of these despite facing heliopause at different times and places.Voyager 1 sailed through the massively stable solar wind for two years before reaching Heliopause, while the stream of solar particles along the Voyager 2 was quick and steady to the limit.At the same time, voyager 1 encountered galactic material intruding into solar bubbles. While voyager 2 instead observed far-reaching solar particles in interstellar space.

 Five spacecraft have been sent so far, and it is still in space, but voyager 2 is the only one that sent back reports. Launched in 1972 and 1973, the voyager 2 is a spacecraft launched by NASA on 20 August 1977 to study outer planets. voyager 2 stopped working 10 years ago.  On January 19, 2006, New Horizons were launched by an Atlas V rocket directly from Cape Horevans Air Force Station at a speed of approximately 16.26 km / s (10.10 mi / s; 58,500 km / h) in Earth- and solar-escape trajectories.Which began its approach phase on Pluto, on 15 January 2015.  On 14 July 2015, it flew 12,500 km (7,800 mi) above the surface of Pluto, and it first detected the dwarf planet, New Horizons recently detected a possible glow of hydrogen gas at the edge of the solar system. But this craft may be out of power even before reaching Heliopause.By early 2030, NASA is considering launching a dedicated interstellar probe.

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

By Surendra Uikey
  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.

By Surendra Uikey
  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.

By Surendra Uikey
  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...
