The Hubble Telescope studies a star-studded skyfield.

In 1784 astronomer William Herschel discovered the globular cluster NGC 6638 by an 18.7-inch telescope and later in the New General Catalog, NGC 6638 is a globular cluster located in the constellation Sagittarius, Hubble's image showing the heart of this globular cluster NGC 6638. shows. The stars are scattered throughout this globular cluster, and for observation, researchers shed light on the star density at the center of NGC 6638, where the stars are stable and tightly bound, a cluster of thousands to millions of stars.

To capture the image of NGC 6638, researchers used two of Hubble's state-of-the-art astronomical instruments, the Wide Field Camera 3 and the Advanced Camera for Surveys, Hubble has been instrumental in helping scientists understand the globular cluster. It is impossible for ground-based telescopes to clearly distinguish the stars in the core of the globular cluster NGC 6638, as distortions caused by Earth's atmosphere are not possible to see clearly.

It is not possible to clearly see globular clusters with any ground-based telescopes, so researchers enlisted the help of Hubble, because Hubble can study any objects orbiting the Earth about 340 miles (550 km) above, The Hubble Telescope has the property that it can reveal what types of stars form globular clusters, how they develop. After the Hubble Telescope, the James Webb Space Telescope will study globular clusters, webb can see star-studded interiors, which are not possible to see by Hubble, because the Webb telescope observes any object at infrared wavelengths.

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...
