Terror case: Mumbai police produce two youths in Mangaluru court

Mangaluru, Apr 23: An astronomical phenomenon, ‘Zero Shadow Day', will be observed in Mangaluru on April 24 and in Udupi on April 25. 

According to a press release from Poornaprajna Amateur Astronomers’ Club, the wonder will commence and people will see their shadows disappear for a few moments at 12:28 pm.

The phenomenon is called as Zero Shadow Day. If a person takes a candle in a dark room and use it to create a shadow of one’s palm on the wall, the hand will cast shadow on the wall as one moves the hand. But when one places the palm on the wall, there will be no shadow.

In the phenomenon, the sun at these times shines exactly above the heads on these days. In astronomy, this point is called as Zenith. The point in the sky directly above an observer at any given location. So it is quite clear now that on Zero Shadow Day, the sun passes through the Zenith as a result of which, all objects will have minimal or no shadow if they are on the ground.

The reason for this happens on some specific days is concerned with astronomy. The earth spins around on its own axis and causes days and nights. It also revolves around the sun causing a year. But the seasons are caused because the axis is tilted at an angle of 23.5 degrees. It is because of this tilt that the sun rises every day in the east gradually moving towards the north till June 21st and then slowly proceeding towards the south till December 21st every year. “We call these days solstice. This means the sun shines between the Tropic of Cancer and Tropic of Capricorn every day passing by the equator on the days we call equinox,” the release stated.

As the earth moves around the sun and revolves on its own axis, for all the people between Tropic of Cancer and Tropic of Capricorn, the Sun at noon moves father and closer to the zenith passing through zenith twice causing two Zero Shadow Days per year. People at Mangaluru will observe this on April 24 and August 18 every year and People in Udupi will observe this on April 25 and August 17 every year.

Places with same latitudes will observe the same days of Zero Shadow but the time would vary with longitude. For example, people of Bengaluru as they share the latitude with Mangaluru will also observe it on April 24. While the people of Mangaluru will observe their shadows disappear at 12.28pm, people of Bengaluru will observe this at 12:17pm. Places like Moodabidri, Bantwal, Sakleshpur and Hassan will also observe Zero Shadow on April 24.

Places like Brahmavar, Karkala, Sringeri, Kudremukha, Chikkamagaluru will observe the Zero Shadow Day on the same day as Udupi on April 25.

New Delhi, May 29: Opining that there is no harm in importing ideas from abroad Swadeshi Jagran Manch, an affiliate of Rashtriya Swayamsevak Sangh, has suggested that India should take a cue from Pakistan and turn the “locust threat” into “chicken feed.

In an interview, Ashwani Mahajan, national co-convener of Swadeshi Jagran Manch (SJM) said: “I saw an article which shows that Pakistan has turned the locust threat into an opportunity by converting it into chicken feed”

“If there is a good idea originating from anywhere, we should be open to exploring such ideas. We should adopt good ideas. There is no harm in that,” he added.

He also shared the article on Twitter and wrote: “Pakistan turns locust threat into chicken feed. Need to understand the idea and replicate it in India.”

The article stated “an innovative pilot project in Pakistan’s Okara district offers a sustainable solution in which farmers earn money by trapping locusts that are turned into high-protein chicken feed by animal feed mills”.

“It was the brainchild of Muhammad Khurshid, a civil servant in the Ministry of National Food Security and Research, and Johar Ali, a bio-technologist from the Pakistan Agricultural Research Council,” according to the article.

Both Pakistan and India have been hit by locust attacks. These are desert locusts, which is one of the 12 species of short-horned grasshoppers. Swarms can comprise billions and travel up to 130 km in a day.

India has been battling the locust attacks with moderate success since December. However, the onset of monsoon could bring more trouble.
