New Image Method Helps Astronomers See a Known Planet

No; it had already been discovered with other telescopes.. The first paragraph says other telescopes had already discovered the planet.

Clue: A team of researchers has used a new computer method to reveal a distant planet in existing observations from the James Webb Space Telescope. The planet, 51 Eridani b, had already been discovered with other telescopes.

A model of the star’s light. The second paragraph says the team modelled the starlight and removed it from the image.

Clue: Light from a star can hide the much fainter planets around it. The team created a model of the starlight and removed it from the telescope image. This revealed the planet in one observation where an earlier analysis had not detected it.

The approach needs further testing.. The final paragraph says further testing is still needed.

Clue: The study appeared in Nature on November 4. The researchers say the approach could help astronomers find and study more planets, although it still needs further testing.
