We are about to reach a milestone that was thought to be impossible. After years of wrangling, cost overruns, threats of cancellation, and lobbying by the science community, the james wbb space telescope is only weeks away from its first images

Scientists began to think about the telescope that would come after the Hubble Space Telescope. The initial launch date for the JWST was set in the early 1990's. The budget was half a billion dollars at that time.

There was a significant re-design by 2005. The project was threatened to be canceled by the Senate because of the poor financial performance. The project continued despite the lobbying effort. It was too tempting to let the project fail.

We are halfway through the year and about to get our first images. Astronomers have been waiting for the launch of the JWST for a long time. The whole world has a stake in the telescope's success, as evidenced by the fact that the project is a cooperative effort.

We are on the verge of a new era of discovery after a long period of testing and calibrating.

We are on the verge of an exciting period of discovery about our universe as we near the end of preparing the observatory. Eric Smith, a program scientist at NASA Headquarters in Washington, said that the release of the first full-colour images will offer a unique moment for us all to stop and marvel. The images will be the culmination of decades of dedication, talent, and dreams.

An international committee of scientists has come up with a list of initial targets for the JWST. The telescope is shown in the first images. The in-depth science will be whetted by them.

The goal for the first images and data is to show the telescope's powerful instruments and to preview the science mission to come. It is certain that they will deliver a long-awaited "WOW" for astronomy and the public.

Even the people who are operating are uncertain about what to expect. They know the images will be amazing, but they can't give us an idea of how great it will be. "Of course, there are things we are expecting and hoping to see, but with a new telescope and this new high-resolution infrared data, we just won't know until we see it."

The mission's science themes will be highlighted in the first images. The themes are the early universe, the evolution of galaxies, and the lifecycle of stars. You will find something to marvel at no matter what your jam is.

Kepler 62f could have liquid water, but only if its atmosphere is rich in carbon dioxide. The James Webb should be able to find out. Artist's Illustration: NASA Ames/JPL-Caltech/T. Pyle

The results of a competitive process will determine what happens next. Expect a steady stream of images and papers from the telescope. If not answered completely, some of the biggest questions in astronomy, cosmology and astrophysics will be pried open a bit further.

We can expect the unexpected as well. The JWST will be a new mission that will surprise us.

There are only a few weeks left to wait. July 12th could be the start of a new era in space science.
