Dark matter is one of the most enigmatic components of our universe, constituting about 27% of its total energy density. Despite this significant presence, scientists have yet to identify what it is. The prevalent theories suggest it does not emit light or interact with baryonic matter via electromagnetic forces, making it practically invisible and detectable

In late December 2024, a significant cosmic discovery was unveiled when astronomers identified an asteroid designated as 2024 YR4. This designation stems from its discovery within the latter half of December, specifically being the 117th asteroid cataloged in that timeframe. The naming conventions in astronomy can often seem arbitrary, but they serve a vital purpose
On April 8, 2024, astronomers encountered a cosmic riddle that defied existing classifications of astronomical phenomena. Initially detected by the Einstein Probe—a sophisticated X-ray space telescope—this mystery event has since been designated as EP240408a. While at first it seemed to fit the profile of a conventional gamma-ray burst—a category of explosive celestial events known for
Asteroid 2024 YR4 has drawn the attention of the international cosmic community, as it races through our solar system with a concerning 1 in 83 chance of colliding with Earth by December 22, 2032. Discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in late December 2024 from a facility in Río Hurtado, Chile, this
In May 2024, Earth experienced an extraordinary solar storm that sent shockwaves through its magnetic field and affected environments far beyond the atmosphere. This solar event was not merely a collection of dazzling auroras dancing across the polar skies; it fundamentally altered the dynamics of Earth’s radiation belts — a development that took the scientific
The notion that human activities on Earth could affect temperatures on the Moon emerged during the unprecedented lockdowns of 2020, instigated by the COVID-19 pandemic. Researchers posited that the substantial reductions in carbon emissions during this period led to a noteworthy decline in the heat radiation that our planet emits – radiation that the Moon
While the thought of a massive asteroid colliding with Earth might seem like the plot of a sci-fi thriller, recent simulations indicate that such an event is not merely speculative fantasy. Humanity faces real threats from space, particularly from asteroids that roam the solar system. An example of this is asteroid Bennu, a hill-sized space
Astrophysics, at its core, seeks to decode the intricate machinations of the universe. To achieve this goal, understanding the massive structures that shape cosmological dynamics is paramount. One of the most significant discoveries affecting our comprehension of the cosmos is the Quipu superstructure. This behemoth, weighing in at an astonishing 200 quadrillion solar masses, has
In the sprawling universe, where billions of galaxies dance across the cosmic stage, the notion that no two are alike has become an essential tenet of modern astrophysics. The recent discovery of the Bullseye Galaxy, or LEDA 1313424, located an astounding 567 million light-years from Earth, serves as a testament to this principle. This galaxy
For centuries, the Grand Canyon has captivated explorers and scientists alike with its grandeur and geological history forged by the relentless force of the Colorado River over millions of years. However, Earth is not the only celestial body adorned with impressive geological formations. The Moon, our enigmatic neighbor in the Solar System, also harbors spectacular
The cosmos is a vast expanse filled with mysteries that challenge our understanding of the universe. Among its most fascinating yet elusive entities are supermassive black holes (SMBHs), titanic gravitational anchors lurking at the centers of galaxies. Despite their celestial prominence, our view of these cosmic giants is frequently obstructed, complicating efforts to fully grasp
At a glance, the Sun appears as an unchanging fixture in our sky, providing light and warmth to the Earth below. However, the reality is far more complex. The Sun is not a solid body but rather a chaotic, ever-evolving sphere of plasma—ionized gas held together by gravitational and electromagnetic forces. Its surface is in
