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...

Planetary Parade 2025: Rare Photo Captures Earth And 7 Planets For The First Time Ever
Experts have claimed it could be the first time all planets including Earth have been captured in a single image.

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 ...

Interstellar Object Could Have Shifted Trajectories of Four Planets, New Research Shows
A recent study suggests that an interstellar object, possibly as massive as eight times Jupiter, may have passed through the solar system billions of years ago, significantly altering the orbits of its outer planets—Jupiter, Saturn, Uranus, and Neptune. Using computer simulations, researchers found that in about 1% of the scenarios, such a close ...

Super-Earth In the Solar System Could Have Rendered Our Planet Uninhabitable, Says Study
A recent study explores a hypothetical super-Earth between Mars and Jupiter, revealing its severe impact on Earth's orbit and climate. Conducted by Florida Institute of Technology scientists Emily Simpson and Howard Chen, the simulation demonstrates how such a planet’s gravity could destabilise neighbouring planets, causing erratic orbits and ext...

Chinese Rover Discovers Evidence Of 3.42 Billion Years Old Ocean On Mars
Like Earth and our solar system's other planets, Mars formed about 4.5 billion years ago. At the time the ocean apparently existed, it might already have begun its transition away from being a hospitable planet.

Discovery of Hidden Ninth Planet in Solar System Could Reshape Astronomy, Claims New Study
Scientists are exploring the possibility of a hidden ninth planet in our solar system. The planet, dubbed Planet Nine, is believed to exist beyond Neptune in the Kuiper Belt. Researchers have noticed unusual gravitational effects on distant objects in this region, which may be influenced by the presence of a large, unseen planet. While it has not b...

New Research Investigates Whether TRAPPIST-1 Planets Are Sending Radio Signals
A team of astronomers from Penn State and the SETI Institute has conducted a significant study on the TRAPPIST-1 star system, aiming to detect possible radio signals between its planets. Over 28 hours, they explored for indications of communication similar to those we use on Earth. Although no signals were found, the research highlighted promising ...

Saturn's Rings To 'Disappear' In 2025. Will They Return? Read About It
This happens because the planet rotates on an axis tilted by 26.7 degrees, and the view of its rings from Earth changes with time.

Our Solar System Will Eventually Be "Crushed And Ground To Dust", Study Finds
Solar Eclipse 2024: The Sun gives energy to life on Earth, and without this star, we wouldn't be here. But even stars have limited lifetimes, and someday our Sun will die and our planet will be swallowed by it before it becomes a white dwarf.
