Leading Space Telescopes by Capability

Space telescopes like JWST, Hubble, and Chandra represent humanity's most powerful eyes on the universe, each excelling in different wavelengths and offering unique observational strengths.

The top 3

1. Most Powerful Space Telescopes: The James Webb Space Telescope (JWST) is the largest and most powerful, observing in infrared, while the Hubble Space Telescope remains crucial for optical and ultraviolet astronomy, and the Chandra X-ray Observatory is the most powerful for X-ray emissions.
2. Top 3 Space Telescope Discoveries: JWST has revealed early galaxies and supermassive black holes, Hubble measured the universe's expansion and provided deep field images, and Spitzer created the first exoplanet weather map and extensive Milky Way maps.
3. Most Expensive Space Telescopes: The James Webb Space Telescope is the costliest, with a lifecycle cost around $10 billion, followed by the Hubble Space Telescope at about $4.7 billion (inflation-adjusted), and the Nancy Grace Roman Space Telescope with a proposed cost of at least $3 billion.
