On June 21, ON the Arctic Circle, the sun descends lower and lower as if it were
about to set, but when it just touches the horizon, it begins to climb higher again,
never having actually 'set'.
Everywhere north of the Arctic Circle, the sun has already been up continuously,
since some time before the solstice, and it'll stay up for the same length of time
after it. The farther north you are, the more time has gone by since the last time
the sun set. In some places just north of the line, it may have been only a few
days. At the extreme, if you're at the north pole, then the sun has been up since
March 21, and it'll stay up until September 22.
The farther from the equator, the weaker the sunlight gets.
No part of Earth gets sunlight all year around, but some parts get sunlight (and dark) for more than 24 hours at a time. At any latitude less than 66.5 degrees from the equator ... north or south ... every point has a sunrise and a sunset every day of the year.
Yes, some part of the planet Jupiter is always in sunlight, although very little sunlight is able to penetrate past the upper cloud level. Jupiter has a day length of 9.84 hours. On the equator, 4.92 hours would be spent in light and 4.92 hours would be spent in darkness.
The Earth is a sphere and it's just the half sphere facing the Sun that can get sunlight. So, half the Earth is always getting sunlight. But it's not the same half all the time, because the Earth rotates. Any particular place gets more hours of daylight in the summer than in the winter. It averages out, over the full year, at 12 hours of daylight and 12 hours of night every 24 hours. So, it's any particular place on Earth that gets light for half the day, on average.
A day on the Moon is 28 days because the Moon keeps one half turned towards the Earth. You can see which part of the Moon has sunlight by looking at it, the bright part is the place where it's day.
Areas near the Equator
Bequerel left his crystals in the sunlight for several hours as part of his experiment.
your question doesnt make sense-that part of the earth has-what does that mean? and the earth rotates, that's what makes night and day, so every part of the earth faces the sun for half of the 24 hours in a day(with the exeption of the north and south poles which are always dark and always light at parts of the year)
We get day and light because the earth rotates on a tilted axis. That takes 24 hours for it. In that time, half of the earth's part is in sunlight and half is ind darkness (facing away from the sun). Half of the earth is in sunlight for 12 hours and the same for the part in darkness. The parts take turns so we have day and night.
Sunlight does not follow the Earth's axis. The Earth's seasons are determined, in part, by the Sun's position to the Earth's axis.
Sunlight touches every part of the earth as the sun's rays reach all corners of the globe.
The farther from the equator, the weaker the sunlight gets.

Well. June 21st or June 22nd every year is the longest day (most hours of sunlight), and December 21st or 22nd every year is the longest night (least hours of sunlight). So there is a 'shortening' of the period of light per day from June to December, and this reverses from December to June.
The part of the moon that is always in sunlight is the "near side" of the moon, which faces Earth and receives light from the sun. This is the side that we see from Earth, as the moon rotates at the same rate that it orbits Earth, keeping the same side facing us.
All of the earth south of 60 degrees South Latitude has at least one day -- 24 hours -- of no sunrise: around June 21. Farther south, the number of days increases until you measure the period of no sunrises at the South Pole, and the duration is about six months, which is the longest period.
The part of Earth that is consistently closest to the Sun is alongside the Equator of the earth. This is the widest part of the Earth's circumference between the North and South Poles.
