Mercury and Earth chorus waves reveal shared magnetospheric plasma behavior
A surprising link between two magnetospheres In a finding that bridges the gap between our planet and its innermost planetary neighbor, researchers have demonstrated that natural electromagnetic chorus waves—long studied in Earth’s magnetosphere—also emerge in Mercury’s much weaker magnetic environment. The study, led by an international team and reported by Riko Seibo, shows strikingly similar…

Mercury and Earth Chorus Waves Show Shared Plasma Behavior Across Magnetospheres
Groundbreaking Discovery: Chorus Waves Beyond Earth Chorus waves—natural electromagnetic vibrations well known within Earth’s magnetosphere—have now been observed in Mercury as well, according to a team of international researchers led by an expert group from Tokyo. The finding shows that Mercury’s relatively weak magnetosphere hosts chorus wave activity with frequency patterns strikingly similar to those…

What Lies Beneath Earth: Exploring Its Hidden Interior
Introduction: Space Is All Around, But What About Below? When we think of space, we often picture the cosmos stretching in every direction. Yet just beneath our feet lies a world just as dynamic and complex: the interior of Earth. While space is indeed a boundless backdrop to our planet, the slice of reality directly…

Perihelion 2026: Earth’s Closest Approach to the Sun Delivers Biggest Sunrise of the Year
What perihelion means for 2026 On January 3, 2026, Earth reaches a point in its orbit known as perihelion, the moment when our planet is closest to the Sun for the year. While the distance is not the sole factor behind seasonal temperatures, perihelion can influence the intensity of sunlight and the apparent size of…

Earth Gets a New Quasi Moon: NASA Confirms 2025 PN7 Has a Stable Distant Path
Introduction: A Tiny Companion in Earth’s Cosmic Neighborhood Earth may have gained a temporary, yet stable, celestial partner. NASA has confirmed the discovery of asteroid 2025 PN7, a small body that doesn’t orbit Earth as a true moon but follows a quirky, long-lasting path that keeps it in a near-Earth neighborhood for roughly five decades.…

Aging Stars Dine on Their Planets: What Earth Can Learn from Red Giants
What the new findings reveal about aging stars Using NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have sharpened our understanding of how red giant stars—aged stars in a late evolutionary stage—interact with their planetary systems. The new results suggest these stellar elders are more destructive to nearby planets than previously believed. As a star exhausts…

Moon Drifting Away From Earth: The Tidal Tug Revealed
Moon drifting away from Earth: the tidal reason The Moon is slowly moving away from Earth, at about 1.5 inches (3.8 centimeters) per year. This measured drift comes from precise lunar laser ranging, where lasers are bounced off corner-cube retroreflectors left on the Moon by Apollo missions and later spacecraft. Over decades of measurements, scientists…

Earth’s New Quasi-Moon: The Discovery of an Asteroid
Introduction to the Discovery In an intriguing turn of events, scientists have uncovered what may be Earth’s newest quasi-moon, an asteroid that remained hidden for decades before being detected by a telescope in Hawaii earlier this year. Initially mistaken for a natural satellite, this discovery sheds light on the complexities of near-Earth objects and their…
