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 ...

Scientists Uncover 'Sunken Worlds' Deep in Earth’s Mantle, Defying Geological Expectations
A new study has uncovered unusual anomalies deep within Earth's mantle, resembling sunken crustal slabs in unexpected locations. Using advanced full-waveform inversion, scientists were able to map these structures, revealing hidden patterns that challenge current geological understanding. These anomalies were discovered far from tectonic activity z...

NASA's TESS Discovers Fastest Disintegrating Planet Ever Seen: What You Need to Know
NASA’s TESS has observed the closest and fastest disintegrating planet, BD+05 4868 Ab, located 141 light-years away. The planet loses a moon’s mass every million years as it is bombarded by its host star. Scientists are examining its massive dust trails, offering rare insights into the composition of terrestrial exoplanets. Researchers from MIT...

Ancient Ice Core from Antarctica May Reveal Climate Mysteries from 1.2 Million Years Ago
A team of scientists in Antarctica has extracted a 2.8-kilometre-long ice core from Little Dome C, believed to be 1.2 million years old. The ice core contains trapped air bubbles and volcanic ash, offering valuable data on climate shifts and the Mid-Pleistocene Transition. The research aims to uncover the cause behind significant climatic changes a...

NASA's LEXI Mission Will Explore Earth’s Magnetic Shield from the Moon
NASA is preparing for the launch of the Lunar Environment Heliospheric X-ray Imager (LEXI) aboard Firefly Aerospace's Blue Ghost lander, scheduled for January 15. The mission will observe Earth’s magnetosphere, capturing X-ray images that reveal how the planet's magnetic shield reacts to solar wind. This project could improve predictions of geoma...

Amateur Astronomer Discovers Unexpected Composition of Jupiter’s Clouds
Recent observations by an amateur astronomer reveal that Jupiter’s clouds may not consist of ammonia ice as previously assumed. Using a technique called band-depth analysis, Steve Hill mapped ammonia concentrations in the planet’s atmosphere, finding reflective layers deeper than expected. These findings suggest the clouds may be composed of am...

Ammonium Hydrosulfide Identified as Primary Component of Jupiter’s Clouds, Not Ammonia
Jupiter’s clouds, long believed to be made of ammonia ice, are now confirmed to consist primarily of ammonium hydrosulfide combined with photochemical materials. This groundbreaking discovery, achieved through collaboration between amateur and professional astronomers, has redefined our understanding of the planet's atmosphere. Using innovative m...

Newly Discovered Oxygen Reaction Existed in Primitive Atmosphere, Sheds Light on Origin of Life
Scientists have uncovered a new way oxygen could form in carbon dioxide-rich atmospheres without the involvement of life. The discovery, led by researchers from the University of Science and Technology of China, shows that a reaction between helium ions and CO2 can produce molecular oxygen. This process challenges traditional methods of life detect...

Underground Hydrogen Reserves Could Power Earth for 200 Years, Study Finds
Trillions of tons of hydrogen have been discovered beneath Earth's surface, offering a potential clean energy solution. A recent study estimates 6.2 trillion tons of hydrogen in rocks and reservoirs, capable of powering the planet for 200 years. While access and economic viability remain challenges, scientists see immense promise in these natural r...

New Study Challenges Planet Formation Models with PDS 70b’s Chemical Mystery
A new study on PDS 70b, a forming exoplanet located 400 light-years away, reveals a significant mismatch between its atmospheric composition and the surrounding protoplanetary disk. This discovery casts doubt on existing planet formation models, suggesting that more research is needed to understand how planets gather materials and elements during t...

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals
A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

Webb Telescope Confirms Planet-Forming Disks Last Longer in Early Universe
The James Webb Space Telescope has revealed that planet-forming disks around stars in the early universe lasted far longer than previously believed. By studying NGC 346, a star cluster in the Small Magellanic Cloud, Webb observed disks surviving for 20–30 million years, challenging current models. This discovery suggests that low-metal environmen...

JWST Discovers Jupiter-Mass Binary Objects in Orion Nebula, Offering New Clues
The James Webb Space Telescope has identified dozens of Jupiter-mass binary objects (JuMBOs) in the Orion Nebula. These enigmatic rogue gas giant pairs orbit each other at distances of 25 to 400 AU. Researchers propose they could be failed stars formed under extreme radiation conditions, ejected planetary systems, or a mix of both. Simulations repl...

Venus Never Had Oceans or Conditions to Support Life, New Study Finds
Scientists from the University of Cambridge have concluded that Venus likely never had oceans or conditions to support life. Their study, published in Nature Astronomy, analysed atmospheric chemistry and volcanic activity. They found that volcanic gases lacked significant steam, indicating the planet's interior has always been dry. This research ha...
