AI Thread Summary
The American Ephemeris Nautical Almanac is the correct title for the 1955 Nautical Almanac. A user is seeking solar position and velocity vectors for three days around October 20, 1955. They provided a link to purchase the almanac on Amazon. The user received the necessary information from the USNO. The discussion highlights the importance of accessing historical astronomical data.

Actually, I believe (Subject) is called the American Ephemeris Nautical Almanac.

If someone has access to it, I'd like the get the solar (heliocentric) position and velocity vectors for 3 days on either side of CE 1955 October 20 07:53:32.6 UT. That corresponds to a JD of 2435400.82884.

As it turns out, the USNO finally contacted me and gave me the page I needed.

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. In case of failure to detect...

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
