NASA's James Webb Space Telescope provides a mesmerizing view of the Milky Way's dense core with its Near-Infrared Camera (NIRCam) instrument. Capturing a portion of the Sagittarius C (Sgr C) region, approximately 300 light-years from the central supermassive black hole Sagittarius A*, the image reveals about 500,000 stars along with intriguing, yet-to-be-explained features.


The cyan-colored section showcases a vast region of ionized hydrogen, unveiling needle-like structures without a consistent orientation. This unprecedented level of resolution and sensitivity from Webb enables astronomers to explore star formation in the challenging environment of the galactic center, pushing the boundaries of current theories in stellar birth.


The observation team, led by undergraduate student Samuel Crowe at the University of Virginia, expresses excitement about the wealth of details unveiled by Webb, marking a significant advancement in our understanding of the extreme conditions within the Milky Way.


There is a group of protostars among the stars, where stars are still forming.


The James Webb Space Telescope reveals a captivating cluster of protostars. These stellar infants, still in the throes of formation and mass accumulation, generate luminous outflows reminiscent of a celestial bonfire amidst an infrared-dark cloud. At the core of this youthful cluster resides a previously identified massive protostar, surpassing 30 times the mass of our Sun. The density of the cloud enveloping these protostars is so profound that it obstructs the light from background stars, creating a deceptive sense of spaciousness in an area teeming with stellar life.


Scattered throughout the image, smaller infrared-dark clouds punctuate the cosmic canvas, resembling voids within the starfield—precisely where the seeds of future stars take root and embark on their luminous journeys. The unprecedented clarity and detail offered by Webb's infrared gaze shed light on the intricate dynamics of stellar birth, unravelling mysteries within one of the Milky Way's most densely populated realms.


The James Webb Space Telescope's Near-Infrared Camera (NIRCam) exposes the grandiose emission of ionized hydrogen enveloping the lower expanse of a dark cloud within the Sagittarius C (Sgr C) region. Bathed in a cyan hue, this large-scale emission typically results from the energetic radiance emitted by nascent massive stars. However, the expansive nature of the region, as unveiled by Webb's meticulous gaze, introduces an element of surprise, prompting further investigation into its intricate dynamics.


Among the captivating features awaiting scrutiny are the chaotic needle-like structures embedded within the ionized hydrogen. Displaying a seemingly haphazard orientation across various directions, these structures beckon scientists like Samuel Crowe, the project's principal investigator, to delve deeper into the cosmic turbulence of the galactic center. As Crowe embarks on unraveling the enigmas encapsulated within this bustling stellar crucible, the data amassed by Webb promises a wealth of insights into the interplay of turbulent, magnetized gas clouds, star formation, and the dynamic interactions sculpting the tumultuous heart of our Milky Way galaxy.


Rubén Fedriani, a co-investigator from the Instituto Astrofísica de Andalucía in Spain, reflects on the treasure trove of data Webb has unveiled, underscoring the commencement of a scientific journey into the extreme environmental intricacies of the galactic center.


Webb's Gaze into the Galactic Heart.




The intricate outlines etched against the cosmic canvas within the Sagittarius C (Sgr C) region have become focal points for astronomers peering through the lens of NASA's James Webb Space Telescope. Positioned approximately 25,000 light-years from Earth, the galactic center serves as an expansive laboratory for studying individual stars with unparalleled precision.


Webb's keen observations empower astronomers to decipher the nuanced relationships between features in this chaotic galaxy center, unraveling cosmic intricacies that extend beyond the reaches of our immediate stellar neighborhood. As scientists delve into the data, probing the profound interplay of elements, they seek answers to fundamental questions—does star formation exhibit unique characteristics in the bustling heart of the Milky Way when compared to the tranquil fringes of its spiral arms?


The breathtaking image captured by Webb is not merely an aesthetic marvel; it heralds a scientific odyssey, promising profound insights into the birth of stars, the synthesis of heavy elements in their nuclear cores, and the cosmic narrative that unfolds within the galaxy's core. Principal investigator Samuel Crowe reflects on the immense scientific potential Webb holds, emphasizing the quest to unravel the origin story of a significant fraction of the universe through the lens of massive star factories nestled in the heart of our galactic home.

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...
