Hubble studies a sparkling galaxy pair NGC 5410 and UGC 8932/PGC 49896.




In this latest image captured by the NASA Hubble Space Telescope, a captivating duo of interacting galaxies, NGC 5410 and UGC 8932/PGC 49896, takes center stage.


The more prominent of the two, NGC 5410, was originally discovered by the renowned British astronomer William Herschel in 1787. Spanning an impressive 80,000 light-years, NGC 5410 features a luminous white bar of stars at its core, indicative of its spiral structure with a medium-sized nucleus and expansive arms. Notably, this spiral galaxy is adorned with numerous youthful, blue star clusters, particularly along its sprawling arms, contributing to the celestial tapestry captured in this stunning Hubble image.


The smaller galaxy in focus, known as UGC 8932 or PGC 49896, possesses a diameter of 60,000 light-years. Distinguished by a radiant blue bar of stars at its center, indicative of the presence of younger stars, its irregular shape suggests distortions likely caused by the gravitational influence of NGC 5410. Situated 180 million light-years away in the Canes Venatici constellation, this interacting pair is observable from the northern hemisphere.


Notably, a stellar stream, resembling a bridge, lies between the two galaxies, a consequence of their gravitational interaction. The Hubble Space Telescope captured this image in 2023, with a specific focus on examining whether interactions between dwarf galaxies contribute to the creation of particle reservoirs that fuel subsequent star formation processes.

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...
