James Webb's Impact on Exoplanetary Science

Scientists continue to research bodies and systems in space and are regularly making new discoveries that allow us to better understand the universe and develop increasingly advanced technologies. Exoplanetary research is not simply a matter of satisfying human curiosity, but also a means by which we can better understand the laws of physics, discover new materials and resources, and develop technologies to improve life on Earth.

A notable tool that scientists have created to aid humankind in these endeavors is the James Webb Space Telescope (JWST), which uses infrared technology to create high-resolution images. Widely considered the most powerful telescope in existence, the James Webb was launched into space by NASA in December 2021. NASA’s James Webb is many times more powerful than the Hubble telescope, its predecessor as the most powerful telescope in the world. The James Webb can see things much older and farther away than the Hubble and provides images that are much higher quality.

A key improvement in the design of the James Webb is the array of hexagonal lightweight beryllium mirrors. Eighteen of these mirrors are arranged together at a total length of 6.5 meters across, and only 46 pounds per segment. It was imperative that the mirrors were lightweight, as it otherwise could be too heavy to launch. These segments are each able to be minutely adjusted down to increments of 10 nanometers. The mirrors are also coated with gold, which helps increase the reflection of light — the primary purpose of the mirrors.

James Webb Exoplanet Atmosphere Discovery

One of the most important things the James Webb will allow scientists to do is study the atmospheres of exoplanets in greater detail. Largely, this will entail studying the composition and abundance of various particles in exoplanetary atmospheres. NASA can potentially glean a lot of valuable information from this research, from understanding different atmospheric dynamics to finding possible markers of life.

The James Webb Space Telescope can not only allow NASA to observe planets that are farther away but can allow observers to more clearly see through the atmosphere as infrared light can more easily pierce particles than other imaging methods. High-quality imaging methods are particularly beneficial for planets that have particularly harsh atmospheric and environmental conditions, such as Venus. Robotic probes are less feasible, due to the fact that they can be quickly destroyed by the conditions. Imaging technologies such as those used by James Webb can benefit researchers by allowing them to gain more understanding of our closest planetary neighbors, not just far-distant celestial bodies.

Finding New Potentially Habitable Worlds

While terraforming a new planet and creating an off-world colony seems like the stuff of science fiction, it is possible it could become a reality in the future — possibly a necessary one. Another habitable planet could solve many potential problems for the human race, from overpopulation to resource drain to dangers such as climate change, nuclear war, or asteroid strike.

It is unlikely that we will find a habitable planet in the near future — let alone develop the means to travel to it and transport the necessary goods. However, many believe it is in our best interest to think about such contingencies as soon as possible.

The James Webb can benefit humankind in our search for habitable worlds by allowing us to find smaller planets and planets that are farther away. The first step is to discover and identify planets in so-called “Goldilocks zones,” but even the few that do reside in these potentially life-nurturing sweet spots are by no means necessarily habitable.

Scientists also need to examine the atmosphere, environment, resources, trajectory, and proximity to other cosmic bodies — all information that James Webb can also help glean. It could possibly even help find extraterrestrial life that may exist elsewhere in the cosmos.

James Webb Telescope Exoplanets Formation

The James Webb Space Telescope’s infrared imaging technology can help people understand more about the current state of planets, as well as how they were formed in the first place. As previously mentioned, Webb can facilitate a better understanding of the composition of atmospheric matter and identify anomalies. These could provide valuable clues as to how planets and various cosmic structures form.

Furthermore, Webb could help scientists find young planets and cosmic bodies, allowing us to see what these structures look like and behave like in their infancy. We may then be able to use this information to better understand our own solar system.

Impact on Future Space Missions

Scientists are constantly trying to improve the safety and capabilities of space missions. We want to avoid tragedies such as the Challenger explosion and prevent various other issues that may negatively impact outcomes. Further, scientists will need to continually develop technology and strategies if we are going to make real strides in the realm of space exploration and exoplanetary exploration.

The James Webb Space Telescope can benefit these developments by demonstrating the fact that valuable assets exist off-planet and raising public interest in space exploration and research. It can also help scientists better understand how various cosmic structures function, allowing them to more effectively develop technologies and procedures to account for any previously unknown variables.
