The constant effort of installing optics equipment for near infrared devices on NASA’s Webb telescope has moved the commission’s attention to nice we are closely monitoring the temperature of the Mid-InfraRed Instrument (MIRI) to its final operating temperature below 7 kelvins (-447 degrees Fahrenheit, or -266 degrees Celsius). We’re continuing other activities this quiet break related to looking at near -infrared devices. As the MIRI dries, other important observer components, such as the rear axle and mirrors, continue to cool and approach their working temperatures.
Last week, the Webb team built a fire to keep Webb’s position in orbit around the Lagrange crater. This is the second burn since Webb arrived in his last orbit in January; these burns will continue from time to time throughout the life of the missionary.
In recent weeks, we’ve shared some of Webb’s proposed scientists, starting with studying the first stars and galaxies on the first Earth. Today, let’s see how Webb can see in our Milky Way wheel where the stars and constellations are formed. Klaus Pontoppidan, Space Telescope Science Institute project scientist for Webb, shares the cool Science devoted to the formation of the stars and the earth with Webb:
“In the first year of scientific work, we expect Webb to write the most recent chapters in the history of our universe – the formation of stars and constellations. Exblanets in their birthplace, and their We are a solar system in its own right.Webb’s infrared powers are useful for showing how stars and constellations form for three reasons: Infrared light is good at seeing through the hidden earth, it collects the hot signatures of young stars. and stars, and it shows the arrival of important chemical compounds, such as water and natural chemicals, “said Klaus Pontoppidan, Webb project scientist, Space Telescope Science Institute, Baltimore, Maryland.
“Let’s take a closer look at each factor. We often hear that infrared light travels through the hidden earth, revealing newborn stars and stars that have been embedded in their orbits. The parent planet travels between clouds 20 times thicker than visible light, because young stars (at cosmic levels, of course) are quickly formed — in a very small space. 100,000 years old – their birth worlds don’t have a chance to disperse, hiding those who are doing this.the critical stage from the naked eye.
“The second reason about young stars and giant stars is that the light is in the infrared more than the visible waves. That means Webb is better at seeing the stars. New young stars and stars and he can help us understand the physics of their early evolution.stellar constellations, but Webb will see new young stars in the middle of the galaxy, the Magellan Worlds, and outside.
“Finally, the infrared field (sometimes called the ‘molecular fingerprint region’) is useful for detecting the nature of chemicals, including water and matter. They are susceptible to molecular ice found in cold molecular clouds before the formation of stars, and NIRCam and NIRSpec, for the first time, will map in full. The wide distribution of ice helps us understand their chemistry.gas near young stars where rock stars are formed, can live.Webb’s earlier scientific research suggests that the way in which earth systems interact with molecules is crucial to the emergence of the way of life as we know it.
“We’ll be paying close attention to MIRI when it’s cold. Although it’s the only mid-infrared sensor on Webb, MIRI is important for understanding the origin of stars and constellations. “
The James Webb Space Telescope is the largest, most powerful, and complex space science ever built.
