NASA’s James Webb Space Telescope Telescope Challenges Old Theories on Mini-Neptune Worlds

New models suggest mini-Neptunes—planets smaller than Neptune with thick gas envelopes—may have solid rocky surfaces instead of molten magma. Data from NASA’s JWST revealed high-pressure atmospheres capable of compressing molten rock into solid crusts. This discovery challenges earlier assumptions and offers key insights into exoplanet composition and planetary …

Is the Universe Slowing Down? Astronomers Detect Signs of Fading Dark Energy

Astronomers from Yonsei University and DESI data analyses indicate dark energy, long believed constant, may be weakening. Corrected supernova results hint that cosmic acceleration is slowing—a possible “cosmic slowdown.” If true, this could help resolve the Hubble tension and redefine how the universe’s expansion and ultimate fate are understood.

Mystery Deepens as Interstellar Comet 3I/ATLAS Brightens Unexpectedly Near the Sun

Interstellar comet 3I/ATLAS defied expectations during its 2025 solar flyby, brightening far faster than predicted. Observatories worldwide recorded a blue coma rich in exotic gases, suggesting unique chemistry from another star system. Scientists are investigating whether its unusual composition or speed caused the outburst, marking a new interstellar mystery.
