How to find data on Earth, planets, motions

AI Thread Summary
To find modern, official data on Earth's motion through space, resources like the JPL's Solar System Dynamics website are recommended. The data includes essential parameters such as eccentricity variations and other orbital characteristics necessary for studying ice ages and planetary perturbations. Researchers can access detailed datasets that cover various periods and celestial mechanics. Utilizing these resources will provide a comprehensive understanding of Earth's movements within the solar system. This information is crucial for analyzing historical climate changes and ice age phenomena.

I am studying the problem of ice ages and I wonder how do I find, in what form the most modern, "official" data about motion of Earth through space? Presumably this includes data about whole solar system for calculating perturbations.

As I understand that set of data should give all different periods such as variation in eccentricity and others.

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
