On July 9, 2025, Earth spun faster than usual, enough to make the day 1.6 milliseconds shorter than the standard 24 hours. Add a leap day every 4 years, except: Years divisible by 100, unless they’re also divisible by 400, giving 365.2425 days/year, which is very close to the real 365.2422.

Evidence for a sub-Jovian planet in the young TWA 7 diskΒ  - Nature Using the James Webb Space Telescope's Mid-Infrared Instrument, a study reports evidence for a direct detection of a cold, sub-Jupiter-mass planet in the disk of the star TWA 7. 

For the first time ever, MIRI on JWST discovered an exoplanet by directl imaging. www.nature.com/articles/s41...

JWST’s Advanced Deep Extragalactic Survey (JADES) analyzed 263 galaxies from the early universe and revealed a significant asymmetry: roughly 66% spin clockwise, while only about 33% rotate counterclockwise. Does this mean the universe is in a spinning black hole? academic.oup.com/mnras/articl...

The Veil Nebula is the remnant of a star roughly 20 times as massive as the Sun that exploded 10,000 years ago, situated about 2400 light-years away in the constellation Cygnus. This view combines three filters of Hubble’s Wide Field Camera 3.

Wall of ice the size of Rhode Island heading toward penguin-packed island off Antarctica A wall of ice the size of Rhode Island is lumbering toward a remote island off Antarctica that’s home to millions of penguins and seals.

A trillion-ton megaberg heads toward South Georgia Island. Calving icebergs are happening more frequently as the climate warms and more fresh water flows into the ocean. apnews.com/article/gian...
