James Webb Telescope Maps Uranus in 3D for the First Time; Data Reveals Hidden Storms, Methane Clouds
The James Webb Space Telescope has produced the first 3D map of Uranus’s upper atmosphere, tracking temperatures and ion densities up to 5,000 kilometers above its clouds. The observations reveal bright auroras shaped by the planet’s tilted magnetic field and confirm that Uranus is still slowly cooling over long timescales.

Scientists Discover High-Density Rocky Planet in LHS 1903 System That Defies Conventional Formation Models
ESA’s CHEOPS mission has uncovered a surprising rocky planet at the outer edge of the LHS 1903 system. Located 116 light-years away, the discovery defies expectations that outer planets are gas giants. Scientists say the finding offers rare evidence that planets can form in gas-depleted environments, challenging current planetary formation models...

Astronomers Discover "Inside-Out" Planetary System With Rocky World Beyond Gas Planets, Challenging Formation Theories
Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

Unique Inside-Out Planetary System Reveals Unexpected Rocky World on the Outer Edge
Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galax...

AI Identifies More Than 1,300 Unusual Objects in Hubble Space Telescope Images
Artificial intelligence has combed through decades of Hubble Space Telescope data, revealing hundreds of unusual celestial objects that astronomers had missed. ESA’s AnomalyMatch neural network scanned around 100 million image cutouts in just days, flagging more than 1,300 anomalies. Among them are colliding galaxies, rare gravitational lenses, a...

ESA’s Solar Orbiter Reveals How Magnetic Avalanches Trigger Solar Flares
New observations from ESA’s Solar Orbiter show that solar flares can be triggered by cascading magnetic disturbances. During a close solar pass, the spacecraft captured fine details of twisted magnetic fields repeatedly breaking and reconnecting, creating a magnetic “avalanche” that amplified a small instability into a powerful flare. The fin...
