NASA Hubble Space Telescope Sees Stellar Glitter in a Cosmic void.

The parts of the Universe which are empty for some reason, there are either fewer galaxies at these places, or not. Cosmic voids of the Universe are vast spaces between filaments (the largest-scale structures in the universe), and voids typically have a diameter of 10 to 100 megapixes, which are specifically defined by the absence of large voids, rich superclusters. The researchers believe, they have less than one-tenth of the average density of mass, which is considered unique in the universe to observe.

The Universe is the part where galaxies are heavier than they seem to be, they are actually beyond this void, and instead form part of other galaxy clusters or clusters. Cosmic voids, such as the one in the Universe, are spaces within the web-like structure of the universe, and there is little or no galaxy present.

The NASA Hubble Space Telescope has detected locations in the Universe that are close to the local cluster, and this area of empty space is at least 150 million light years. Researchers believe that for this perspective, our own Milky Way galaxy is estimated at 150,000 light-years, which makes the void immense in its nothingness.

Unlike a spiral and elliptical galaxy in the Universe, a galaxy KK 246 looks like a black velvet sheet glowing. KK 246, known as ESO 461-036, and is a dwarf irregular galaxy, locally residing within the void, where there is a vast area of empty space. In the Universe, the KK246 galaxy is known to have a single vast mass of habitats, and to some, along with 15 others that have been temporarily identified by researchers.

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...
