In Antarctica, the length of a day depends on the season. During the austral summer (October to February), there can be up to 24 hours of daylight due to the midnight sun. Conversely, during the austral winter (March to September), there can be up to 24 hours of darkness due to the polar night.
Helium makes up about 24% of the sun's mass.
As many as we might want if we ever start living there. Hours are made up by people.
the stellar mass was at least three times that of the Sun, a black hole
You may not realize that you have asked the question in an odd way. When you say northernmost, you are asking for the latitude that is farthest north where the sun can be above the horizon, or below the horizon, for 24 hours. That would be zero degrees north latitude, the north pole. The 'above which' idea may bring us to conclude the answer is any latitude arbitrarily close to but not equal to zero degrees. See what I mean? [Compensate for south as needed] You might have meant to ask for the lowest northern latitude where you can experience the sun above the horizon, or below the horizon, for 24 hours. That would be about 23.439 degrees north latitude.
The northpole :)
During the Antarctic summer, the sun can stay up for 24 hours a day for several months due to the phenomenon known as the midnight sun. Conversely, during the Antarctic winter, the sun may not rise above the horizon for several months, resulting in polar night.
It is up 24 hours a day and in winter it isn't up at all!
The time the sun stays in the sky varies depending on the time of year and your location. At the equator, day and night are roughly equal, while closer to the poles, the sun can stay in the sky for up to 24 hours during the summer months.
Garlic can stay in your system for up to 24 hours after consumption.
seriously? Like 8 hours?
Yes. Prepared formula can only stay out for 2 hours. If you make a batch of formula it will be good up to 48 hours.
It all depends on the time of year. If you're right exactly on the Arctic Circle, then: -- December 21: sun is down exactly 24 hours -- March 21: sun is up 12 hours, down 12 hours -- June 21: sun is up exactly 24 hours -- September 21: sun is up 12 hours, down 12 hours -- December 21: sun is down exactly 24 hours
Visitors to the north pole are presumably carrying the clocks they bring with them, so they'll count 24 hours on June 21, just as they would anywhere else. If you're asking about hours of 'daylight' or 'sun-up', then that answer is similar. If you're standing at the north pole on June 21, then the sun is above the horizon continuously, for the whole 24 hours. As a matter of fact, the sun has been up for the past 3 months, since March 21, and it'll stay up for another 3 months, until September 21.
it means to stay awake for 24 hours straight
Thawed breast milk can stay out at room temperature for up to 2 hours. After that, it should be refrigerated or used within 24 hours.
In 24 hours!
