AI Thread Summary
To calculate the positions of stars and planets in the night sky, the Astropy library in Python is highly recommended, as it provides accurate positioning for astronomical objects based on time and location on Earth. Understanding celestial coordinate systems is essential, and resources like Wikipedia and specific educational websites can help with this foundational knowledge. Users can find download information for Astropy on its official website. The discussion emphasizes the importance of both mathematical formulas and programming skills for effective astronomical calculations. Utilizing these tools can enhance the accuracy of observing celestial bodies.

Hello to all of you,

my question is:how to calculate the star or planet position in night sky? give me a methemetical formula...

If you are able to program in python, there's an excellent library called astropy that can be used to give the position of an astronomical object at any time at any place on Earth, in all the common coordinate systems. If you're not familiar with how stars are located in the sky, I suggest you look at http://en.wikipedia.org/wiki/Celestial_coordinate_system and https://dept.astro.lsa.umich.edu/ugactivities/Labs/coords/index.html

thankx for giving information, i will read it,
 
you give me a link to download a astropy...
 
thank you
 

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...
