You can easily locate the North Star by using the Big Dipper. The Big Dipper contains stars known as "pointer stars," which can be used to locate the North Star.  To start, locate the Big Dipper. The Big Dipper is a constellation made up of seven stars. The constellation is found in the northern sky. In the spring and summer months, the Big Dipper will be somewhat high in the sky. In the autumn and winter months, it'll be lower in the sky.  The Big Dipper is given its name because it's shaped somewhat like a bowl with a handle. Four stars form a trapezoid-like shape, the bowl portion. Stemming off of these four stars are three more stars, forming the shape of a slightly bent handle.  Once you've located the Big Dipper, you can use it to find the North Star. To do so, look at the two bright stars that form the side of the bowl farthest away from the handle's tip. These are the "pointer stars." Draw an imaginary line connecting the pointer stars. Extend that line five times the distance between the pointer stars. You should eventually reach a somewhat bright star. This is the North Star. Note that you do not actually have to see the North Star with this method.  If clouds or trees or mountains are in the way, the North Star is still there near the end of the fifth pointer length.  That point is less than three degrees from the North Star and the North Celestial Pole. The Little Dipper is the constellation that contains the North Star. The tip of the Little Dipper's handle is the north star. If you're able to locate the Little Dipper, you can easily spot the north star.  You can use the Big Dipper to find the Little Dipper. Once you find the Big Dipper, look away from it as if water was coming out of the "open" part of the dipper. The Little Dipper will appear as a mirror image of the Big Dipper. It is also a constellation made up of seven stars. Four stars form a trapezoid base, and three extend out from this base to form a handle. The last star extending outward is the North Star.  If you live in an urban area, it can be difficult to locate the Little Dipper. It is also difficult to discern on bright moonlit or hazy nights.  You may be better off trying another method. Using the Big or Little Dipper are the most common means to locate the North Star. However, if the Big Dipper is low in the sky it can be difficult. Fortunately, you can use the constellation Cassiopeia to locate the North Star.  Cassiopeia is a constellation that consists of five stars. They form an "M" or "W" shape. Cassiopeia is located in the north sky. In earlier hours, the constellation looks more like an "M." Between midnight and dawn, the constellation looks more like a "W." In the months of February and March, Cassiopeia is especially likely to appear as a "W."  The three stars that form the middle portion of the "M" or "W" can be used to roughly locate the North Star. Look at this point as if it were an arrow. Follow the direction of the arrow forward. You should eventually land on a somewhat bright star. This is the North Star.  Note that you will have to actually see the North Star for this method to work.

One-sentence summary -- Use the pointer stars of the Big Dipper. Locate the tip of the Little Dipper's handle. Rely on the arrow in the Cassiopeia constellation.

Q: Make sure one of the oven racks in the center position so your tilapia can cook evenly. Turn your oven on and let it preheat completely before putting your fish in to cook. You can also use a toaster oven to make single portions if you want. Put a layer of non-stick cooking spray on a 13 in × 9 in (33 cm × 23 cm) baking pan so the tilapia doesn’t get stuck on the pan. Lay the filets down on the cooking pan so they have about 1 inch (2.5 cm) of space between them.   Thaw frozen tilapia completely before cooking with it, or else it may not get an even bake. Line your cooking pan with aluminum foil if you want an easy cleanup later. Set the baking pan on the center rack of your oven so the filets get an even cook. Leave the oven door closed while the fish cooks or else some of the heat will escape. Check your fish after 10 minutes to see if it’s white and flaky. Remove the tilapia from the oven once it’s finished. Make sure your tilapia cooks until it has an internal temperature of 145 °F (63 °C). Otherwise, you may get sick from foodborne bacteria. Immediately serve the tilapia after it comes out of your oven so you can enjoy it while it’s still warm. Eat your fish with sides of fresh vegetables to have a healthy meal. Squeeze a fresh lemon wedge over the fish if you want to add more citrus flavor to it. You can store leftovers in your fridge for up to 4 days or in the freezer for up to 3 months.
A: Preheat your oven to 425 °F (218 °C). Put your tilapia filets in an oiled cooking pan. Put the tilapia in your oven for 10-12 minutes. Serve the tilapia while it’s still hot.

Article: " While much less common, por nada is another way of saying “you're welcome” that roughly translates to “it's nothing.”  More literally, por nada means something along the lines of for nothing. In Spanish, por is a preposition usually used to mean “for” or “on account of.”  Note that this phrase is not used in every Spanish-speaking country. It is used in various Latin American countries, like Costa Rica and Puerto Rico, but it is not used in all Latin American countries or in Spain. This translates to "at your command/at the command" meaning that if there's anything else you can assist with, you will be very much willing to do it at the person's command. It is very polite and very common. Some countries use "tu" more prominently than "usted" (and vice versa) and this depends if you use 'a su orden' or 'a tu orden'. "A la orden" is neutral.
Question: What is a summary of what this article is about?
Switch to "por nada. Say "a la orden" o "a su/tu orden".
