Demonstrating the Concept of Parallax with James Webb Space Telescope

TL;DR

This paper demonstrates the concept of parallax by measuring the James Webb Space Telescope's position using simultaneous observations from two ground-based telescopes separated by over 4000 km, illustrating a fundamental astronomy principle.

Contribution

It provides a practical demonstration of parallax measurement using the JWST and ground-based telescopes, bridging theoretical teaching and observational practice.

Findings

Successful parallax measurement of JWST

Ground-based telescopes effectively demonstrate parallax

Educational value for astronomy teaching

Abstract

We measured the parallax of the James Webb Space Telescope based on near simultaneous observations using the Lulin One-meter Telescope and the GROWTH India Telescope, separated at a distance of ~4214 km. This serves a great demonstration for the concept of parallax commonly taught in introductory astronomy courses.
