A new study suggests that the exoplanet orbiting the star Formalhaut that was supposedly imaged and then later theorized to be nothing more than a dust cloud might be a planet after all.

The ring and planets of Formalhaut

New observations from the new ground-based submillimeter ALMA telescope in Chile have given astronomers a clearer picture of the ring/disk of debris orbiting the nearby star Formalhaut. Moreover, the data suggests that two planets that are shepherding that ring are smaller than previously thought, no larger than a few times the size of the Earth.

In a preprint paper published today on the Los Alamos astro-ph website, astronomers have concluded that the exoplanet orbiting the star Formalhaut might not exist. This planet, the first exoplanet ever thought to be directly imaged in visible light, was first described in a paper published in 2008, and was actually tracked in its orbit over several years, as shown in the image on the right.

The new research used the Spitzer Space Telescope to see if the planet’s heat could be detected in infrared wavelengths. Unfortunately, the scientists found nothing.
