Could Earth Have Sent Life To Venus? New Study Explores 'Panspermia' As A Possible Explanation
Recent models suggest asteroid impacts could have transferred surface materials and potentially microbes from Earth to Venus, where they may have adapted to the clouds.

NASA’s Parker Solar Probe Observes Solar Wind Making ‘U-Turn’, Shedding Light on Space Weather
NASA’s Parker Solar Probe captured solar wind reversing toward the sun, revealing how magnetic fields recycle coronal material. This process, seen during a close flyby, helps refine models of space weather and may allow scientists to better predict solar storms that can impact satellites, communications, and power systems across the solar system.

Study Traces Moon-Forming Impact to an Inner Solar System Neighbour Named Theia
A new isotopic study reveals that Theia—the Mars-sized body that struck Earth 4.5 billion years ago to form the Moon—likely originated in the inner Solar System, close to Earth’s birthplace. By comparing heavy-element isotope ratios in lunar rocks, Earth samples, and meteorites, researchers found identical signatures, showing both worlds form...

Uranus and Neptune May Be More Rock Than Ice, New Research Suggests
A new pre-print study proposes that Uranus and Neptune might not be “ice giants” after all. Using assumption-free models, scientists found their interiors could range from mostly icy to mostly rocky, suggesting we know far less about these distant worlds and that new missions are essential to solve the mystery.

Astronomers Capture Sharpest-Ever Solar Flare Images with NSF’s DKIST Telescope
Astronomers have achieved a major breakthrough by capturing the sharpest images of a solar flare ever recorded, using the National Science Foundation’s Daniel K. Inouye Solar Telescope (DKIST). Observed at the hydrogen-alpha wavelength during the decay of an X1.3-class solar flare, the images unveiled hundreds of ultra-fine coronal loops averagin...

NASA Launches AI Model To Understand Solar Eruptions, Predict Space Weather
NASA is raising the bar in solar science with the debut of the Surya Heliophysics Foundational Model, an artificial intelligence system built to decode the Sun's complex behavior.

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.

Meteorite From Outer Solar System Challenges Planet Formation Timeline in Early Solar System
A meteorite from the outer solar system may upend long-held beliefs about planetary formation. New research shows rocky planets like Earth may have formed at the same time as those beyond Jupiter. The findings challenge previous models and suggest a more synchronised origin for rocky worlds across the solar system, with major implications for plane...

Parker Solar Probe Witnesses Unprecedented Sunward Plasma Jet Driven by Magnetic Reconnection
NASA's Parker Solar Probe has made a groundbreaking discovery, observing an unprecedented plasma explosion in the Sun's corona. This rare event produced a sunward jet of particles, with protons accelerated to nearly 1,000 times the expected energy. Scientists traced this phenomenon back to a magnetic reconnection site, where twisted solar magnetic ...

Jupiter Was Once Twice as Big With 50x Stronger Magnetism, Says New Study
A 2025 study reveals Jupiter was once twice its current size with 50x stronger magnetism. Using moon orbits for data, researchers show how early Jupiter shaped the solar system’s structure.
