Did Black Hole Radiation Shape the Universe?
- Saturday March 29, 2025
- Written by Gadgets 360 Staff
A study suggests that Hawking radiation, first proposed by Stephen Hawking, may have influenced the universe’s structure. According to reports, primordial black holes that existed in the early universe could have evaporated through Hawking radiation, impacting matter distribution. The research explores how these black holes might have shaped gala...

Smallest Galaxy Ever Found: Andromeda XXXV Defies Cosmic Evolution Models
- Thursday March 13, 2025
- Written by Gadgets 360 Staff
Astronomers have discovered Andromeda XXXV, the smallest and faintest known galaxy, located 3 million light-years away. It challenges existing models of galaxy formation, as similar small galaxies were thought to be destroyed in the early universe. Researchers are studying how it retained conditions for star formation despite harsh cosmic environme...

Black Hole Singularities May Not Exist, Say Scientists
- Friday March 7, 2025
- Written by Gadgets 360 Staff
A new study questions the existence of black hole singularities, suggesting refinements to Einstein’s equations using quantum gravity concepts. Researchers argue that infinite density points may not be real, replacing them with highly curved but finite regions of space-time. While direct observation remains difficult, gravitational waves and earl...

NASA Supercomputer Finds Spiral Structure in the Oort Cloud’s Inner Region
- Thursday February 27, 2025
- Written by Gadgets 360 Staff
A NASA supercomputer model suggests that the Oort Cloud’s inner structure forms a spiral, influenced by galactic tides. The Oort Cloud, a distant icy shell surrounding the solar system, has remained unobservable due to its vast distance. Researchers believe this finding could redefine understanding of how comets originate and interact with cosmic...

Astronomers Spot Galaxy NGC 3640 With a Past of Consuming Smaller Galaxies
- Tuesday February 25, 2025
- Written by Gadgets 360 Staff
Recent observations of NGC 3640 reveal a history of merging with smaller galaxies. Located 88 million light-years away, the elliptical galaxy is suspected to be on a collision course with NGC 3641. The Very Large Telescope captured structural distortions, hinting at previous mergers. Researchers have identified ancient stars acting as fossil marker...

Unusual X-ray Flash in Large Magellanic Cloud Puzzles Astronomers
- Tuesday February 25, 2025
- Written by Gadgets 360 Staff
A brief yet intense X-ray flash, XRT 200515, was detected in NASA's Chandra telescope data from 2000. The signal, originating from the Large Magellanic Cloud, has left scientists debating its cause. Possible explanations include a neutron star pulling in gas from a companion star or a powerful flare from a distant magnetar. Researchers also specula...

Weak Gravitational Lensing Examines Universe’s Structure: What You Need to Know
- Thursday February 13, 2025
- Written by Gadgets 360 Staff
The universe's large-scale uniformity is under scrutiny through weak gravitational lensing. Researchers are analysing data from the Euclid Space Telescope to detect potential anisotropies in cosmic expansion. If confirmed, these findings could challenge the fundamental Cosmological Principle, which assumes the universe has no preferred direction. T...

The NASA/ESA Hubble Space Telescope has captured a stunning image of SN 2022aajn, a Type Ia supernova in the constellation Gemini. Located 600 million light-years away, the explosion was first detected in November 2022. Type Ia supernovae serve as essential cosmic distance markers due to their predictable brightness.

JWST Detects Unexpectedly Massive Black Holes in the Early Universe
- Monday February 3, 2025
- Written by Gadgets 360 Staff
A new study led by Jorryt Matthee of ISTA reveals that black holes in early galaxies were significantly more massive than expected. Using JWST data, researchers found that some black holes accounted for nearly 10% of their galaxy's stellar mass—far exceeding the 0.01% ratio seen in modern galaxies. The findings challenge existing growth models, s...

Boson stars, invisible celestial objects theorised to form from axions, are now at the centre of dark matter research. Axions, light and wave-like bosons, may cluster under gravity, forming these mysterious entities. Unlike normal stars, boson stars neither emit light nor interact with regular matter in observable ways. With sizes ranging from smal...
