Opening the Infrared Treasure Chest with JWST free webinar

?On March 15, 2025, at 9:30 PM Eastern Daylight Time (EDT), the Astronomical League of the Philippines (ALP) will host a free webinar titled "Opening the Infrared Treasure Chest with JWST." The event features Dr. John C. Mather, a Nobel laureate in Physics (2006) and Senior Astrophysicist at NASA's Goddard Space Flight Center. Dr. Mather, who served as the Senior Project Scientist for the James Webb Space Telescope (JWST) from 1995 to 2023, will discuss the development, infrared capabilities, and recent discoveries of the JWST.

Opening the Infrared Treasure Chest with JWST free webinar

The James Webb Space Telescope, launched on December 25, 2021, and fully operational since July 2022, represents a monumental leap in space observation technology. With its 6.5-meter primary mirror and instruments sensitive to wavelengths from 0.6 to 28 micrometers, JWST enables astronomers to explore the universe in unprecedented detail. Its infrared capabilities allow it to peer through cosmic dust and observe phenomena that were previously obscured or undetectable by visible-light telescopes.?

One of the primary scientific objectives of JWST is to study the formation and evolution of galaxies. By observing galaxies at various stages of development, JWST provides insights into how these massive structures assemble and change over time. Notably, JWST has identified some of the earliest galaxies formed after the Big Bang, offering clues about the conditions of the early universe. These observations help scientists understand the processes that led to the large-scale structure of the cosmos we see today.?

In addition to galaxies, JWST has made significant contributions to our understanding of star formation. Its infrared instruments can penetrate dense clouds of gas and dust where stars are born, revealing the initial stages of stellar development. This capability allows astronomers to study the physical conditions and processes that lead to star formation, enhancing our knowledge of how stars like our Sun come into existence.?

JWST's ability to analyze the atmospheres of exoplanets marks a significant advancement in the search for habitable worlds. By observing the light that passes through an exoplanet's atmosphere during transit, JWST can detect the presence of molecules such as water vapor, carbon dioxide, and methane. These observations are crucial for assessing the potential habitability of exoplanets and searching for signs of life beyond our solar system.?

The telescope's contributions extend to our own solar system as well. JWST has observed planets, moons, and other celestial bodies, providing new data on their composition, atmospheres, and surface properties. For instance, its observations of the outer planets and their moons offer fresh insights into their formation and evolution, enriching our understanding of the solar system's history.?

Dr. Mather's involvement with JWST dates back to its inception. As the Senior Project Scientist, he played a pivotal role in defining the mission's scientific goals and overseeing its development. His leadership ensured that JWST would address some of the most pressing questions in astronomy and cosmology. Dr. Mather's previous work with the Cosmic Background Explorer (COBE) satellite, which measured the cosmic microwave background radiation with remarkable precision, earned him the Nobel Prize in Physics in 2006. ?
