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...

New Research Reveals Mars’ Red Colour Linked to Ancient Water Presence
A recent study suggests that Mars’ red hue originates from ferrihydrite, an iron oxide that forms in water-rich environments. Scientists recreated Martian dust in labs and found that the mineral remained stable despite the planet’s dry conditions. Data from orbiting spacecraft and rovers confirm this discovery, reshaping theories about Mars’ ...

Ancient Martian Ocean Shoreline Discovered Beneath Surface by Zhurong Rover
China's Zhurong rover has uncovered evidence of an ancient ocean on Mars, with ground-penetrating radar detecting a buried shoreline beneath the Utopia Basin. The rover’s scans revealed sloping sand layers similar to those found on Earth’s beaches, reinforcing theories of long-term water presence. Experts highlight that these formations are not...

Scientists Observe Rare Plastic Ice, A Hybrid Form of Ice and Water, Under Extreme Pressure and Heat
Researchers have observed plastic ice, a phase where water molecules rotate while staying in a solid structure. The discovery, made under extreme pressure and heat, could provide new insights into the composition of icy exoplanets and moons. The findings suggest plastic ice VII may have existed in Europa and Titan's interiors and could influence nu...

Curiosity Rover Finds Evidence of Liquid Water on Mars, Expanding Habitability Timeline
Reports from NASA’s Curiosity rover reveal evidence of ancient liquid water on Mars, challenging previous models. Images from Gale Crater show wave-like ripples, similar to Earth’s lakebeds. Scientists suggest the findings indicate Mars once had a denser atmosphere, which allowed liquid water to exist longer than previously believed. This disco...

A Neptune-Like Exoplanet Is Racing Through Space at Record Speed
Scientists have detected an exoplanet racing through space at 1.2 million mph, making it the fastest known planet. The Neptune-sized world orbits a hypervelocity star, first hinted at in 2011 via gravitational microlensing. Astronomers, using Keck Observatory and Gaia data, have confirmed the system’s extreme speed, suggesting it may even leave t...

Astronomers Spot a High-Speed Star That May Carry a Planet With It
Astronomers have identified a celestial object moving through the Milky Way at over 1.2 million mph. Believed to be a small star with a possible massive exoplanet, the discovery could mark the fastest-known planetary system. If its speed exceeds 1.3 million mph, it may eventually escape the galaxy. Scientists are still verifying whether it is the s...

A Star With a Planet May Be Racing Through the Galaxy at Record Speed
Astronomers have identified a potential record-breaking exoplanet system moving at 1.2 million mph. Detected through microlensing, the discovery suggests a low-mass star with an orbiting planet is racing through the Milky Way. Data from the Keck Observatory and ESA’s Gaia satellite indicate a high-speed celestial body that may eventually escape t...

Newly Confirmed Super-Earth HD 20794 d May Support Life in Habitable Zone
A super-Earth, HD 20794 d, has been confirmed within a habitable zone 20 light years from Earth. The planet, first detected in 2022, has a mass six times that of Earth and orbits a sun-like star. Although its elliptical orbit affects temperature stability, its potential to sustain liquid water makes it a key target for upcoming space missions. Scie...

JWST Unveils HH 30’s Protoplanetary Disk, Showing Dust Grains and Jets
The James Webb Space Telescope has captured an extraordinary image of HH 30, a protoplanetary disk in the Taurus constellation. The dense dust disk conceals the central star, while bright jets extend outward, interacting with surrounding gas. Microscopic dust grains within the disk have been identified, playing a crucial role in planetary formation...

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...

Astronomers Discover Water and Carbon Dioxide in WASP-166 b's Atmosphere
Astronomers have detected water and carbon dioxide in the atmosphere of WASP-166 b, a hot super-Neptune exoplanet. Using data from the James Webb Space Telescope (JWST), the findings also noted ammonia in smaller quantities. WASP-166 b, located 368 light-years away, is a massive planet that orbits its star every 5.44 days, with a temperature of 1,2...

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...
