Planet formation cannot be modelled or simulated from scratch, but theoretical studies rely on results from experiments, either as verification or as input parameters. Many experiments require microgravity conditions, as the mechanisms to be investigated are too subtle to be studied in normal laboratory...
We predict that transitions between these different states can happen in as little as a decade. Therefore, it is incorrect to assume that sudden changes in the orbits only happen near apse antialignment.doi:10.1016/j.icarus.2005.10.005Farmer, Alison J...
Level 2 is always present, but having different influences depending on timing. The 60 year cycle in Earth’s temperature is most likely controlled by the PDO index which over the last 100 years aligns with global temperature. The PDO index is often portrayed by the warmist crowd as an “...
At least 15 different basins of attraction (BOAs) are highlighted in the new map. (Image credit: Valade et al. 2024) The map shows dozens of objects spread out across billions of light-years around the Shapley Concentration, such as the S...
“tracking” measurements between the ground geodetic stations and satellites have been used to determine the satellite orbits from which models of the Earth’s gravity have been derived. This has revealed that the gravity field is much more complex than previously thought, reflecting the ...
The first life on Earth arose some 3.8 billion years ago, most likely in tidal pools or on the seabeds. It consisted of single-celled organisms. Over time, they evolved to become more complex plants and animals. Today the planet hosts millions of species of different life forms and more ...

These signals become more and more consistent between the different stations as the forthcoming activity is approaching. These signals may last some hours during the days preceding a large activity. Moreover, their distribution seems to depend on the location of the burst of activity (La Fournaise...
Image: Ganymede has an area dotted with craters brilliant. In this detailed mosaic taken by the Galileo spacecraft around Jupiter from 1995 to 2003, the colors of the moon were very different. Credit: Galileo Project, DLR, JPL, NASA
NB: The extrasolar planets often appear to have elliptical orbits, which vary enormously temperature, which is not ideal for the emergence of life. Image: Satellite photo: notice on the enlarged photo, frail membrane of the ground atmosphere which protects the life. ...
