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, Apr 29: WhatsApp on Tuesday said it will now allow up to eight people to connect on a group video call as an increasing number of people turn to digital platforms to connect with friends and family amid the COVID-19 pandemic.

The Facebook-owned company said over the last month, people on average are spending over 15 billion minutes talking each day on WhatsApp calls, well above a typical day before the pandemic.

"...we see that people all over the world are turning to voice and video calling on WhatsApp more than ever before. Group calling has been particularly useful and our users have asked to connect with more people at once," WhatsApp said in a blogpost.

Starting Tuesday, the company is doubling the number of participants one can have on a WhatsApp video or voice call from 4 to 8 people at a time, it added.

WhatsApp emphasised that like written messages, all calls on its platform are protected with end-to-end encryption.

"We have built group calling in a way that makes it available for as many users as possible, including people on lower-end devices and slow network conditions," it added.

WhatsApp said that to access the new, higher participant limit on WhatsApp calls, all participants in a call need to update to the latest version of WhatsApp available on iPhone or Android.

Video calling tools like Google Meet, Microsoft Teams, Zoom and others have also seen a significant jump in userbase and traffic as people connect while maintaining social distancing amid the coronavirus outbreak.

Last week, Facebook had introduced Messenger Rooms that will soon hold up to 50 people with no time limit.

It had added that the company will also add ways to create rooms from Instagram Direct, WhatsApp and Portal.

Noting that between WhatsApp and Messenger, more than 700 million accounts participate in calls every day, Facebook had said, adding that video calling on Messenger and WhatsApp more than doubled in many countries.

Also, views of Facebook Live and Instagram Live videos have also increased significantly in March, it said.

Bengaluru, Jan 7: Karnataka Chief Minister BS Yediyurappa on Monday said the much-awaited cabinet expansion will take place in about a week to 10 days and that he wants to complete the exercise before his proposed visit to Davos to attend the World Economic Forum meet later this month.

"Cabinet expansion has to be done in a week or 8-10 days. There is also information that Amit Shah will be coming to Bengaluru on January 16 or 18. Before that I will go to Delhi and get things cleared and will expand the cabinet at the earliest," Mr Yediyurappa said.

Speaking to reporters in Bengaluru, he said he wanted to complete the exercise before his Davos visit.

"I will make all efforts to expand the cabinet before that," he said.

With Mr Yediyurappa making it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the December 5 bypolls on BJP tickets will be made ministers, lobbying has been on within the party for the remaining ministerial berths.

Currently, there are 18 ministers, including the Chief Minister, in the cabinet that has a sanctioned strength of 34.

Cabinet expansion will not be an easy task for the Chief Minister as he will have to strike a balance by accommodating the victorious disqualified legislators as promised and also make space for the old guards, upset at being "neglected" in the first round of the induction exercise.

He also has to give adequate representation to various castes and regions in his cabinet and also deal with the allocation of key portfolios.

The Chief Minister, who has indicated that the ministry expansion may take place any time after Sankranti, is likely to travel to Davos on January 20, according to sources.

BS Yediyurappa, along with Union ministers Piyush Goyal and Mansukh Mandaviya, as well as Chief Ministers Amarinder Singh, Kamal Nath, are expected to join over 100 Indian CEOs at Davos in Switzerland later this month for the WEF's 50th annual meeting, which will be attended by thousands from across the globe.
