Researchers are looking forward to a glimpse of colliding worlds in action from NASA's cutting-edge space observatory.
After the James Webb Space Telescope finishes its commissioning period and releases its first operational images on July 12, the observatory will dive into science in earnest. And one of the telescope's first-year investigations will include a close-up view of the strange neighborhood of Beta Pictoris.
The young star, just 63 light years away from us, is surrounded by a dusty disc full of debris left over from its formation. It's a crowded space, hosting "at least two planets [and] a jumble of smaller, rocky bodies," researchers said in a 2021 press release(opens in new tab) about the investigation.
While the research has numerous directions, one key aspect is watching a young planetary system evolving as planetesimals (the predecessors to planets) collide. Because Beta Pictoris is wreathed in dust, researchers will be using Webb's infrared light to peer through the debris and see what is happening in high definition.
Webb will have decades of past work to draw upon, including ground-based observatories and space observations from the Hubble Space Telescope. We know from such studies that Beta Pictoris hosts at least two gigantic planets, both much more massive than Jupiter. Researchers also glimpsed the first known exocomets, or comets beyond our solar system, whirling in the debris cloud. READ MORE...
