Chapter 1: The Journey of the James Webb Space Telescope

The astronomical community has invested an astounding amount in the James Webb Space Telescope. But will this hefty investment yield significant results?

Initially, the proposal for this project was intended to be both swift and cost-effective. NASA aimed to create a telescope for around $500 million, which was expected to unveil the mysteries of the early universe within just eleven years. However, it took a staggering twenty-five years to complete.

Now, with costs soaring past $10 billion, the James Webb Space Telescope is finally poised for launch. This summer, it will be transported by ship to Kourou, South America. If all goes according to plan, an Ariane rocket will elevate the telescope into orbit this October. By November, it will reach its final orbit, located one million miles from Earth, with the first images expected early next year, providing an unprecedented view of the infrared universe.

From its inception, the telescope was seen as a successor to the aging Hubble Space Telescope. However, this comparison, while appealing, is somewhat misleading. Hubble is a highly versatile instrument, offering astronomers a range of tools to explore the cosmos. In contrast, the James Webb is specifically designed for infrared observation.

Infrared light, often associated with heat, is not easily visible. Telescopes that focus on this wavelength act somewhat like thermometers, detecting faint heat sources from the distant universe. Constructing such telescopes on Earth presents challenges since infrared light is readily absorbed by the atmosphere, rendering ground-based observations ineffective.

To bypass these limitations, infrared telescopes are often deployed at high altitudes using specialized aircraft or, like the James Webb, are placed in space where they can operate away from Earth's thermal interference. To ensure optimal performance, the telescope must be maintained at a frigid temperature of -220°C (-370°F) to prevent the instruments from emitting heat that could distort the data collected.

These formidable challenges contribute to the mission's steep expenses. Although NASA initially anticipated developing new technologies, they significantly underestimated the associated costs. The engineering demands have been immense, including a massive sunshield to protect the telescope from solar heat and a vast gold-plated mirror that relies on a hundred individual motors for precise operation.

What is the significance of an infrared telescope for astronomers? Its ability to look across vast distances, nearly to the very edge of the observable universe, is unparalleled. Hubble, which operates in the optical spectrum visible to the human eye, cannot reach these distant realms. Consequently, it cannot look back to the moments when the first stars and galaxies ignited.

When we observe deep space, we are effectively looking back in time due to the finite speed of light. As the universe expands, the wavelengths of light traveling from its early moments stretch. Over billions of years, light that once fell within the optical range has shifted to the infrared spectrum, which Hubble cannot detect.

The James Webb telescope is set to provide an unmatched view into this epoch, allowing astronomers to identify the first stars and witness the primordial fluctuations from the Big Bang that eventually formed galaxies and shaped the modern universe. In doing so, it will reveal an era previously shrouded in mystery.

Closer to home, this powerful telescope can also uncover objects that are currently difficult to observe, such as brown dwarfs—dim stars that emit minimal light—and exoplanets, which are typically overwhelmed by the brightness of their host stars. Remarkably, the telescope might even capture direct images of these distant worlds, offering insights into their atmospheric conditions.

However, not all astronomers have welcomed the telescope's escalating costs. The increasing budget has diverted funds from other projects, leading to the James Webb dominating the astronomical landscape—an outcome that many hope will prove fruitful.

Yet, success is not guaranteed. The telescope's complexity and its remote location pose significant risks. After Hubble's launch in 1990, astronomers were dismayed to discover a flaw in its mirror that compromised observations. Fortunately, Hubble was designed for astronaut repairs, allowing for a replacement.

In contrast, the James Webb is too far for astronauts to reach, and it has not been engineered for manual repairs. This mission is a one-time endeavor—if it fails to function properly, it will not yield any results.

A recent high-energy physics experiment has uncovered issues with the standard model. Conducted at Fermilab in Chicago, the study examined the magnetic moment of muons—subatomic particles similar yet heavier than electrons. The findings confirmed earlier suspicions that the observed value deviates from standard model predictions. If verified, this could indicate unexpected phenomena, potentially leading physicists to revise existing theories.

However, these results are preliminary. Researchers must gather and analyze additional data to affirm their conclusions. Moreover, the findings will undergo rigorous scrutiny for errors, and calculations will be meticulously validated. Should confirmation occur, it would rejuvenate a field that has appeared stagnant.

In a prior article, I suggested that astronomers play a limited role in advising contemporary governments, a claim I now realize is incorrect. In Bhutan, a small Himalayan nation, astronomers were consulted on the optimal strategy for rolling out COVID-19 vaccinations.

After assessing the celestial configurations, the astronomers (or possibly astrologers) recommended a two-month delay until conditions improved. Remarkably, this approach did not lead to negative outcomes. The country has reported only one COVID-related death, and nearly the entire population received their first vaccination within a week after the two-month period.

Much of the reporting surrounding health, science, and space exploration tends to be exaggerated, unrealistic, and misleading. These topics are intricate and often lack straightforward answers. Hence, there is a pressing need for thorough analysis, thoughtful discussion, and exploration of potential pathways forward.
