Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, Parker Solar Probe hurtled through the solar atmosphere at 430,000 miles per hour.

2024 saw unprecedented global temperatures, following on from the remarkable warmth of 2023. It also became the first year with an average temperature clearly exceeding 1.5°C above the pre-industrial level – a threshold set by the Paris Agreement to significantly reduce the risks

JWST spectrum of K2-18b’s atmosphere. The detections of methane and carbon dioxide suggest the presence of an ocean underneath a hydrogen-rich atmosphere. There’s also a hint of DMS, which on Earth is tied to biological activity.

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/giant-…

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 instrument highlighting emissions

The International Astronomical Union (IAU) recognized 128 new moons in orbit around Saturn, discovered by astronomers from Taiwan, Canada, the United States and France. Saturn’s new grand total of 274 moons is almost twice as many as all the rest of the moons in our solar system

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?

Aerial view of the Thwaites Glacier, Antarctica. This glacier covers an area about the size of Florida. It has the largest ocean front of any glacier in the world.

The NSF Solar Telescope in Hawaii, the largest solar telescope globally, with the Visible Tunable Filtergraph (VTF), has taken its first images.The new VTF has an unparalleled combination of imaging, spectral, and polarimetric capabilities.

Scientists discover a new colour by laser stimulation of only M cones and not L or S, which in principle would send a colour signal to the brain that never occurs in natural vision. science.org/doi/10.1126/...

On July 9, 2025, Earth faster than usual, enough to make the day 1.6 milliseconds shorter than 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.
