Stars like our Sun burn for about nine or 10 billion years . So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go.
The latest sunset always comes on or near June 27 at mid-northern latitudes every year. Bottom line: Why don’t the latest sunsets come on the longest day (the solstice)? In a nutshell, it’s a discrepancy between the sun and the clock.
The summer solstice occurred at 5:44 p.m. Saturday, and it marks the beginning of its namesake season. Saturday will also include 15 hours, 20 minutes, and 52 seconds of daylight for Buffalo, making it the longest day of the year. Sunrise on solstice Saturday will be at 5:36 a.m. with sunset at 8:57 p.m.
This year the official winter solstice, also known as the ‘hibernal solstice’, takes places on 21st December 2020. In the Northern Hemisphere, in London the sun will set at approximately 15:53, marking the shortest period of daylight and the longest night of the year.
For about a billion years, the sun will burn as a red giant. Then, the hydrogen in that outer core will deplete, leaving an abundance of helium. Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies.
Roughly speaking, the golden hour is the first hour of light after sunrise and the last hour of light before sunset. So, there are actually two golden hours every day. However, this is just an approximation. Depending on the season and your location the golden hour might be a lot shorter or longer.
As with twilight, there is civil dusk, nautical dusk, and astronomical dusk, occurring at the exact moment when the center of the sun’s disk is at 6°, 12°, and 18° below the horizon, respectively. Stages of dawn occur before sunrise, in the reverse order as described for dusk.
Winter solstice 2020, the shortest day of year and the official start of winter , is on Monday, December 21 .
The Northern Hemisphere, including India, will witness the longest daytime of the year on Sunday, June 21. The sun will reach its highest position in the sky, and the shadows will disappear at noon if you are in Ujjain, Gandhi Nagar or essentially any place along the tropic of cancer on this day .
Kolkata has the longest day in the month of June. Over the course of June in Kolkata, the length of the day is essentially constant. The shortest day of the month is June 1, with 13 hours, 25 minutes of daylight and the longest day is June 21, with 13 hours, 31 minutes of daylight.
The timing of the June solstice is not based on a specific calendar date or time; it all depends on when the Sun reaches its northernmost point from the equator. Therefore, the solstice won’t always occur on the same day. Currently, it shifts between June 20 , 21, and 22.
In January, each day gains between 90 seconds and two minutes of daylight. In February, about two and a half minutes of daylight are added each day. As the sun moves higher in the sky from March through June, there are about two more minutes of daylight per day.
