#proximab — Public Fediverse posts

Seven years ago, my group launched the Pale Red Dot observing campaign whose purpose was very simple: to confirm the existence of #Proximab, the nearest candidate habitable #exoplanet.

Evidence for its existence had been found three years earlier by myself, but such extraordinary discoveriy require stronger support than most scientific results.

And it gained support, as of today, from as many as three different telescopes and instruments.

Stellar and substellar companions from Gaia EDR3.

According to this new paper, #Gaia #astrometry sensitivity would be just enough to independently verify the existence of Proxima c.

Although the existence is in serious doubt, Gaia could help resolve the situation by providing a clear detection or by ruling out the existence of the planet.
