ETs Sending Out Signals From Ceres?

Recently astronomers noticed that the lights on Ceres blinked at intervals of about every nine hours, raising the question, is this an artificial beacon transmitting coded signals?

Baffled astronomers made the announcement that deepened the mystery of the bright spots on the dwarf planet Ceres. They recently claimed that the famous spots blinked at intervals of around nine hours.

With the latest discovery, some UFO hunters suggested that it is a definitive evidence of the theory that bright spots on Ceres are artificial beacons transmitting coded signals. The signals would guide ET spaceships coming in to land at a base on the dwarf planet, the largest body being discovered in the asteroid belt between Mars and Jupiter.

The unexpected fluctuations in the brightness of the mystery spots were observed in the spectrograph of High Accuracy Radial velocity Planet Searcher (HARPS) at ESO’s La Silla Observatory in Chile. The widely known spots, called faculae, can be found in an 80-kilometer crater Occator.

Some UFO enthusiasts speculate that it is a signal. It could be a warning signal, a radar tower, or a greeting signal. It must be there for a purpose, according to UFO researchers. Does humanity need to signal back?

Scientists have a better explanation for the variations in brightness. They suspect the fluctuations could be due to the activity below the surface that involves churning out plumes of material that reflect light when the planet faces the Sun. The brightness decreases when the plumes evaporate. The process could repeat in the next rotation when the planet faces the Sun again.

However, scientists admit they don’t have enough data and observations to confirm the hypothesis.

Are the scientists correct, or are they trying to cover up evidence of life on other planets?
