10-Year-Old Writes To NASA To Restore Pluto's Planet Status, Agency Responds
In the letter, she apologised for any handwriting or spelling mistakes, making her letter even more emotional.

Rubin Observatory Discovers Over 11,000 Asteroids Within Weeks of Imaging
The Vera Rubin Observatory has discovered over 11,000 new asteroids within weeks of early observations. The findings highlight its ability to rapidly map the solar system and improve tracking of near-Earth objects for planetary defence.

Astronomers Find Planet Close To Solar System With Earth-Like Size And Orbit
Researchers estimate that the planet has about a 50% chance of being in its star's Hoble zone.

VLT’s GRAVITY Instrument Detects ‘Tug’ from Colossal Exomoon; Could Be Largest Natural Satellite Ever Found
Astronomers have spotted a subtle orbital wobble around the massive exoplanet HD 206893 B, hinting at the presence of a gigantic moon nearly half Jupiter’s mass. If confirmed, it would be unlike any moon known, potentially redefining how scientists distinguish between moons, planets, and brown dwarfs.

Earth To Make Its Closest Approach To The Sun This Week: Will It Affect The Seasons?
Perihelion is when a planet or celestial body reaches its closest point to the Sun in its orbit.

Why Venus Is the Brightest Morning Star Visible From Earth
Venus appears so bright in the sky due to reflective sulfuric acid clouds, its closeness to Earth, and sunlight scattering that creates optical effects like a glory.

Misaligned Exoplanet Is Challenging How We Think Solar Systems Form
Astronomers studying the dwarf-star system TOI-3884b have uncovered a striking anomaly: the planet’s orbit is sharply misaligned with its star’s rotation. Using multicolour transit observations, researchers detected repeated starspot-crossing events that revealed the planet passes over cooler regions on the stellar surface. Follow-up monitoring...

Mars Orbiters Take Rare Images of Interstellar Comet 3I/ATLAS Zooming Past Red Planet
ExoMars TGO captured a series of images with its Colour and Stereo Surface Imaging System (CaSSIS).

Mercury Has Shrunk by Several Kilometers Over Billions of Years, Scientists Report
Mercury’s surface reveals it has been shrinking for billions of years due to cooling and faulting. A new study estimates the planet’s radius has contracted by 2.7–5.6 kilometers, offering the most precise figures yet. The findings sharpen understanding of Mercury’s thermal evolution and could help scientists apply the same techniques to tec...

James Webb Telescope Detects Potential Gas Giant Exoplanet Just 4 Light-Years Away
Astronomers using JWST have spotted a possible gas giant orbiting Alpha Centauri A, only 4 light-years away. If confirmed, it would be the closest exoplanet to a Sun-like star ever imaged. The discovery could challenge current models of planetary formation in binary systems and open new opportunities for studying nearby worlds.

New Dwarf Planet Discovery Challenges Planet Nine Hypothesis
The discovery of a potential dwarf planet, 2017 OF201, in the farthest reaches of the solar system is reshaping our understanding of space. With a highly elongated orbit and large size, it contradicts the Planet Nine hypothesis, which predicted orbital clustering among distant objects. This finding not only questions the existence of a ninth planet...

Asteroid Vesta May Be a Fragment of a Lost Planet, Say Scientists
Vesta, once believed to be a stalled protoplanet, may be a fragment of a long-lost differentiated planet. Using refined gravity data from NASA’s Dawn mission, scientists found it lacks a dense core, suggesting it was ejected during a primordial impact. This revised view may apply to other asteroids and reshape planetary formation theories.

Primordial Helium-3 May Be Locked in Earth’s Core, Study Finds
Helium-3, an isotope formed during the solar system's birth, may be trapped in Earth's core, a study suggests. Researchers at the University of Tokyo found that helium can mix with iron at extreme heat and pressure, allowing it to remain in Earth's solid core. This discovery could help determine how quickly the planet formed, with a rapid formation...

Mysterious Interstellar Object Might Have Shifted Four Planets’ Paths, Study Finds
A mysterious interstellar object, estimated to be eight times the mass of Jupiter, may have significantly altered the orbits of Jupiter, Saturn, Uranus, and Neptune billions of years ago. A study suggests that this body passed remarkably close to the Sun, potentially influencing planetary trajectories. Simulations conducted by researchers indicate ...
