NASA’s Chandra X-ray Observatory has unveiled the underperformance of a black hole, contrary to astronomers’ expectations. Dubbed H1821+643, this quasar, a rapidly growing supermassive black hole located approximately 3.4 billion light-years away from Earth, exhibits characteristics that challenge conventional understanding. Quasars, distinguished by their vigorous material consumption and consequent radiation emissions, typically wield significant influence […]

Why brown dwarfs—objects smaller than stars—live lonely lives as they age?
Brown dwarfs, enigmatic objects residing in the Twilight Zone between stars and planets, have captured the attention of astronomers yet again. Despite their name, which seems to suggest a dull hue, these celestial beings are anything but ordinary. Unlike stars, they lack the mass needed to sustain hydrogen fusion, marking them as failed stars or […]
Hubble Observes Galaxy LEDA 42160 Battling intergalactic gas Pressure in Virgo Cluster.
This Hubble image shows dwarf galaxy, LEDA 42160. NASA/ESA’s Hubble Space Telescope recently captured a striking image of LEDA 42160, a diminutive galaxy situated approximately 52 million light-years away in the Virgo constellation. Despite its small stature, this galaxy finds itself in the midst of a cosmic struggle within the dense environment of the […]
Space Butterfly Nursery: Where Hundreds of Baby Stars Take Flight.
W40, the cosmic “Space Butterfly,” is a nebula—a colossal cloud of gas and dust—with its “wings” formed by massive stars expelling gas outward. In a mesmerizing display of cosmic artistry, NASA’s Spitzer Space Telescope unveils the celestial spectacle of Westerhout 40 (W40), affectionately dubbed the “Space Butterfly.” This infrared image captures the essence of […]
Unveiling the Cosmic Tendrils: NASA’s Webb Explores NGC 604 in Detail
The study of star formation and the dynamic environments they inhabit is a complex yet captivating realm in cosmic exploration. NASA’s James Webb Space Telescope has brought unprecedented clarity to this field, unraveling the intricacies of the processes involved. Recent images captured by Webb’s NIRCam and MIRI instruments offer a detailed glimpse into the star-forming […]
Fresh eRosita’s X-Ray Revelations Validate Cosmological Predictions.
Clusters of galaxies, comprising hundreds or even thousands of individual galaxies, reside at the crossroads of immense, interwoven filaments of cosmic matter. These filaments weave the intricate fabric of the universe. Within each galaxy cluster, gravitational forces draw everything toward its center, causing the intergalactic gas to compress and heat up, emitting X-rays that reveal […]
In 1997, Hubble captured the celestial Maternity Ward N81 in the Small Magellanic Cloud.
In a cosmic spectacle captured by the NASA Hubble Space Telescope, the celestial maternity ward known as N81 unveils a breathtaking “family portrait” of youthful, ultra-bright stars nestled within their embryonic cloud of radiant gases. Situated 200,000 light-years away in the Small Magellanic Cloud (SMC), a small irregular satellite galaxy of our Milky Way, […]
Red giant and white dwarf: Nova explosion in the northern crown witnesses the emergence of a ‘new’ star.
In this animation of a nova, a red giant star and a white dwarf engage in a mesmerizing cosmic dance. The red giant, a vast sphere adorned in shades of red, orange, and white, orbits the white dwarf. The side facing the white dwarf exhibits the lightest shades. Meanwhile, the white dwarf remains concealed […]
NASA’s planetary radar took some pictures of the slowly rotating asteroid 2008 OS7 for the purpose of observation.
In the lead-up to its close encounter with Earth on Feb. 2, asteroid 2008 OS7 was meticulously observed through a series of images taken by the formidable 230-foot Goldstone Solar System Radar antenna near Barstow, California. As asteroid 2008 OS7 approached Earth on Feb. 2, NASA’s Deep Space Network planetary radar provided unprecedented detailed […]
POLIX Onboard XPoSat Initiates Scientific Observations.
The Indian X-ray Polarimeter (POLIX) has initiated its scientific observations as part of India’s X-ray polarimetry mission XPoSat. During the period from January 15-18, 2024, POLIX conducted observations leading to the generation of a pulse profile of the Crab pulsar. This pulsating star, located near the center of the Crab Nebula, exhibits a rapid […]
