“If you think about it, that’s beyond what humanity has ever moved., Nelson said. „ŞNow we are beginning to understand what the web can and will do. It will explore objects in the Solar System and the atmospheres of exoplanets orbiting other stars, providing clues as to whether their atmospheres are similar to our own.
According to NASA Deputy Administrator Pam Melroy, the Webb mission, estimated to last 10 years, has enough extra fuel capacity to operate for 20 years.
Mission engineers said the observatory was performing better than expected. The team continues to work on developing strategies to avoid impacts by micrometeoroids like the one that hit Webb’s mirror in May.
What to expect
The space observatory, launched in December, will be able to peer into the atmospheres of exoplanets and observe some of the first galaxies created after the universe began, observing them through infrared light, which is invisible to the human eye.
Webb started making his first images a few weeks ago and is still capturing some images that will be shared on July 12. Those packet color images will be the result of 120 hours of observation, about five days of data.
The telescope’s original goal was to see the first stars and galaxies in the universe, to see “how the universe first lit up,” said Eric Smith, a Web program researcher and principal investigator in NASA’s Astrophysics Division.
The Webb Telescope’s clear views of the universe will revolutionize astronomy
The exact number and nature of the images has not been revealed, but “each of them will reveal a different aspect of the universe with unprecedented detail and sensitivity,” said Klaus Pontoppidan, a Webb project researcher at the Space Telescope Science Institute.
The first edition highlights Webb’s scientific abilities as well as the ability of his giant gold mirror and scientific equipment to produce amazing images.
The images will also show examples of the violent life cycle of stars, how galaxies interact and grow, and how collisions between galaxies cause stars to form. We can also expect to see how an exoplanet’s first spectrum, or wavelength of light and different colors, reveals the characteristics of other worlds.
The telescope’s near-infrared imager and slitless spectrograph instrument completed preparations this week. The instrument can use a special prism to scatter light collected from cosmic sources to create three distinct rainbows that reveal more than 2,000 shades of color in the infrared from a single observation.
It is particularly useful when observing exoplanets to determine whether they have atmospheres, and to pick out the atoms and molecules inside the atmosphere when starlight passes through it and determine its composition.
The best part is that the Webb team is only at the beginning of the mission, and the space observatory will make the data it collects public so that scientists around the world can “begin a common journey of discovery,” Pontoppidan said.
