The Halley's comet is expected to make its presence felt when Earth will move through the particles shed by the Halley's comet in 1986.
As the particles hit the Earth’s atmosphere they glow for a short period of time to form a meteoroid shower known as 'Orionid meteor shower'.
Halley's Comet was discovered by Edmund Halley in 1705 but is believed to have been recognized for millennia. The comet returns about every 75 years and was last seen from Earth in 1986. It will next be seen in 2061.
The Cornell University’s Ornithology Lab, has launched a massive bird count survey across the globe to identify and record large number of indigenous and rare birds.
The institute has allowed common citizens to participate in the survey by launching an app known as eBird and Merlin bird app, which contains large databases of rare birds, which will make their identification easy.
