Primordial black holes (PBHs) have captured the interest of astronomers and cosmologists, presenting a tantalizing enigma since their theoretical inception in the 1960s. Hypothesized to have formed in the chaotic early moments of the universe, these black holes emerged from regions of space where matter was dense enough to provoke gravitational collapse. Unlike their stellar

Recent findings by a collaborative team of researchers from the NASA Goddard Space Flight Center and the University of Arizona are reshaping our understanding of the Moon’s internal structure. The study proposes the existence of a partially molten layer between the Moon’s rocky mantle and its solid metal core, a hypothesis that has long been
Supermassive black holes, with masses reaching up to a billion times that of the Sun, represent some of the cosmos’s most formidable and mysterious entities. Their presence at the centers of galaxies often concerns astronomers, as their growth and formation challenge our understanding of cosmic evolution. This article delves into the complexities of these astronomical
The Earth-Moon system stands out as an exception in a solar neighborhood filled with a variety of astronomical relationships. Unlike other planets that may boast multiple moons or none at all, Earth hosts a surprisingly large satellite—the Moon. This dynamic duo presents significant questions surrounding the Moon’s origins. What if the Moon wasn’t merely a
On October 3, 2024, an astonishing event unfolded on our solar neighbor, as the Sun released an X9.0 solar flare, marking the most potent eruption witnessed in the last seven years. This intense solar activity was not just a standalone event; it was coupled with a halo coronal mass ejection (CME) directed straight at Earth.
Launched in the late 1970s, the Voyager spacecraft—Voyager 1 and Voyager 2—have become symbols of humanity’s quest for knowledge beyond our planet. Over 45 years later, these spacecraft continue their journey through the cosmos, providing unparalleled insights into the deep solar system and the interstellar space that lies beyond. With each passing year, as they
As October unfolds, the Sun has kicked off the month with a powerful exhibition of solar activity, initiating a series of breathtaking events that have captivated scientists and skywatchers alike. On October 1, the Sun unleashed a massive solar flare measuring X7.1, marking it as the second most intense flare recorded during the current solar
Nestled in the frigid expanse of our Solar System, 5.7 billion kilometers from the Sun, lies Pluto, the renowned dwarf planet. Among its intriguing companions is Charon, Pluto’s largest moon, which bears striking resemblances to its parent body. Charon is not merely a satellite; it represents a fascinating binary system with Pluto, where both celestial
In a remarkable turn of astronomical events, January 2023 marked the discovery of a new comet, aptly designated as C/2023 A3 (Tsuchinshan-ATLAS). While the universe frequently reveals new comets, this particular one piqued the interest of astronomers due to its promising potential for brightness. Comet watchers are familiar with the unpredictability inherent in these celestial
The universe is a realm of enigmas, where black holes stand as some of the most perplexing entities. Among them, primordial black holes (PBHs) are particularly fascinating, as they are theorized to have emerged within moments of the Big Bang—distortions in spacetime birthed from exceedingly dense regions of matter. Recent research led by a team
The concept of timekeeping has always been fundamental to human civilization, influencing everything from daily routines to global communications. As humanity extends its reach beyond Earth, especially with plans for a sustained lunar presence, the importance of a standardized time measurement becomes not only beneficial but essential. NASA’s recent initiative to establish a Coordinated Lunar
In early May of this year, a remarkable aurora displayed the immense power of solar storms and radiation. However, beyond these spectacular displays, the Sun can unleash something far more destructive known as “solar particle events”. These events involve blasts of protons directly from the Sun’s surface shooting out into space, potentially causing severe damage
