Welcome to today's Science Letters
In a report published on NASA's website in July 2023, a new study uses the Webb telescope to embark on a magical 3D visualization journey, revealing 5,000 galaxies in the universe.
The Webb Telescope, known as the successor to Hubble, is able to see into corners of the universe that we could not reach before because of its larger mirror surface and more powerful observation capabilities. The use of 3D visualization technology has brought our understanding of the universe to a higher level.
So how did the researchers use the Webb telescope and 3D visualization techniques to reveal these galaxies?
The researchers first conducted a deep exploration of the starry sky through the Webb telescope. The telescope interprets the collected optical and infrared signals and converts them into digital information that can be processed. It's like when we take a picture with a camera, and the sensors inside the camera convert light into data that can be stored.
Next, this digital information is entered into a special computer program that is used to generate a 3D model. This step is like post-processing the photos we take, using special techniques to transform the two-dimensional image into a three-dimensional scene that can be viewed on the screen.
In this way, researchers have been able to reveal galaxies hidden in endless darkness, allowing us to understand the universe from a whole new perspective. The process is full of challenges, but it is also full of the magical power of technology. And this power is the embodiment of our passion and curiosity for the unknown.
Have you ever wondered why our eyes can't see these galaxies? This is because dust and gas in the universe block the light they emit, making it impossible for our naked eyes to see directly. But Webb's infrared observations can penetrate this dust and gas to help us "see" seemingly invisible galaxies.
Seeing this, do you begin to imagine what it would be like if we could explore this mysterious universe for ourselves? Perhaps in the not-too-distant future, the power of technology will bring us closer and closer to this dream.
At the end of the article, let's think about a question together: when we see these galaxies, does it mean that we see the past? Because light takes time to travel, the galaxies we see now are actually what they were a long, long time ago. For us, every time we watch the starry sky, it is actually a journey through time.
The power of technology is helping us push the boundaries of our understanding of the universe and give us a deeper understanding of the amazing world in which we live. There are more unknowns waiting for us to explore in the future, let's look forward to it together and see where technology will take us.
