Webb Telescope Reveals Massive Cosmic Dust in Sagittarius B2
- Here's a breakdown of the information provided about the Sagittarius B2 star-forming cloud,based on the text and image descriptions:
- This means it's a place in space where new stars are being born.
- * NIRCam (Near-Infrared Camera): The first image shows the region as seen by NIRCam.It reveals the stars within the cloud.
Here’s a breakdown of the information provided about the Sagittarius B2 star-forming cloud,based on the text and image descriptions:
What is Sagittarius B2?
* Its a star-forming region. This means it’s a place in space where new stars are being born.
* It’s a very dense cloud of gas and dust.
How has it been observed?
* NIRCam (Near-Infrared Camera): The first image shows the region as seen by NIRCam.It reveals the stars within the cloud.
* MIRI (Mid-Infrared Instrument): The second image shows the region as seen by MIRI. It reveals the dust clouds illuminated by the stars.
What do the images show?
* NIRCam image: Shows stars within the cloud.
* MIRI Image: Shows pink and purple dust clouds surrounding very dark regions. The dark regions are so dense that even infrared light can’t penetrate them. These dark areas are where the raw ingredients for stars are hidden.
Key takeaway:
The two different instruments (NIRCam and MIRI) on the James Webb space Telescope reveal different aspects of the Sagittarius B2 cloud. NIRCam sees the stars, while MIRI sees the dust and the areas where stars are forming but are still hidden from view.
