We may not be alone, after all. Sightings of UFOs (unidentified flying objects) and encounters with aliens have long been a hot topic. Just recently there was a flood of reports of a UFO over Hong Kong, and on the mainland, an airport shut down when officials were unable to identify a craft that was hovering nearby.
To date, however, nobody has come up with credible proof that aliens do exist. But now we have Gliese 581g.
The planet is far away, but it might be able to support life, scientists say. We don't know if intelligent beings like us live there, much less if they have the technology to visit us. But someone does seem to be visiting earth, if we're to believe frequent reports of UFO sightings. Early last month, many people in Hong Kong claimed to have seen UFOs.
The Hong Kong Observatory said it received eight reports of UFO sightings on September 8 in the two days after.
Among the reported cases, says Woo Wang-chun, a scientific officer at the observatory, 'three involved a ring of light hovering at a bus stop near Tai Lam Tunnel'. The simple explanation, Woo says, is the heavy rain that night caused witnesses to mistake the refracted light of a street lamp for a UFO.
September 8 was the night when a record number of lightning strikes hit Hong Kong during a storm. The observatory reported that in the hour after midnight more than 13,000 bolts of lightning hit the ground.
