The blackness and emptiness
Crossed only by thin bright fences

Having children plays a complicated role in the rate we age

New Scientist Space - Space Headlines - Fri, 11/07/2025 - 2:00pm
The effort of reproducing may divert energy away from repairing DNA or fighting illness, which could drive ageing, but a new study suggests that is only the case when environmental conditions are tough

Habitable Zone Planets Around Red Dwarfs Aren't Likely To Host Exomoons

Universe Today - Fri, 11/07/2025 - 12:38pm

The planets in our Solar System host hundreds of moons, so it seems likely that planets in other solar systems do, too. New research examines the likelihood of rocky planets around M dwarfs having exomoons, and it doesn't look good. They don't last long enough for them to give life a helping hand like Earth's moon has.

Copernicus Sentinel-1D journey to space

ESO Top News - Fri, 11/07/2025 - 11:30am
Video: 00:03:39

The Copernicus Sentinel-1D satellite has joined the Sentinel-1 mission in orbit. Launch took place on 4 November 2025 at 22:02 CET (18:02 local time) on board an Ariane 6 launcher from Europe’s Spaceport in French Guiana.

The Sentinel-1 mission delivers high-resolution radar images of Earth’s surface, performing in all weathers, day-and-night. This service is used by disaster response teams, environmental agencies, maritime authorities and climate scientists, who depend on frequent updates of critical data.

Sentinel-1D will work in tandem with Sentinel-1C, flying in the same orbit but 180° apart, to optimise global coverage and data delivery. Both satellites have a C-band synthetic aperture radar (SAR) instrument on board, which captures high-resolution imagery of Earth’s surface. They are also equipped with Automatic Identification System (AIS) instruments to improve detection and tracking of ships. When Sentinel-1D is fully operational, it will enable more frequent AIS observations, including data on vessel identity, location and direction of passage, enabling precise tracking.

Sentinel-1D was launched on Europe’s heavy-lift rocket Ariane 6 on flight designated VA265.
