Rocket Payload fairings and Aircraft fairings

Image
First of all: What is a payload fairing? a payload fairing is an object on a Rocket or Aircraft, Fairings can disconnect from an object, Payload fairings are used mostly on rockets to protect whatever is inside the fairing through the atmosphere, the atmosphere is mostly made out of Nitrogen gas, which is very cold & if the rocket is going too fast, the rocket will burn as it ascends through the atmosphere. so, a payload fairing can protect a Space Probe through Earth’s atmosphere and after its outside of the atmosphere, it will be disconnected, because it’s no longer needed. After that, the rocket reaches Low Earth Orbit or get into an orbit around the Sun. Payload fairings can be useful for rockets but what about aircrafts? Even though rocket fairings can disconnect, a fairing on an aircraft can also disconnect, but nobody, not even the pilot can disconnect it, why? Because the fairing on an aircraft is used as a structure, not as a fairing.

An Artful Sky over Lofoten Islands

Image
  Can the night sky be both art and science? If so, perhaps the featured image is an example. The digital panorama was composed of 10 landscape and 10 sky images all taken on the same night, from the same location, and with the same camera. Iconic features in the image have been artfully brightened, and the ground nearby was artfully illuminated. Visible in the foreground is the creative photographer anchoring an amazing view from the rugged Lofoten Islands of Norway, two months ago, by holding a lamp. Far in the distance are three prominent arches: our Milky Way Galaxy on the left, while a scientifically-unusual double-arced aurora is documented on the right. A meteor is highlighted between them. Other notable skylights include, left to right, the Andromeda Galaxy, the planet Jupiter, the star Vega, and the stars that compose the Big Dipper asterism.

25 Brightest Stars in the Night Sky

Image
  Do you know the names of some of the brightest stars? It's likely that you do, even though some bright stars have names so old they date back to near the beginning of written language. Many world cultures have their own names for the brightest stars, and it is culturally and historically important to remember them. In the interest of clear global communication, however, the International Astronomical Union (IAU) has begun to designate standardized star names. Featured here in true color are the 25 brightest stars in the night sky, currently as seen by humans, coupled with their IAU-recognized names. Some star names have interesting meanings, including Sirius ("the scorcher" in Latin), Vega ("falling" in Arabic), and Antares ("rival to Mars" in Greek). You are likely even familiar with the name of at least one star too dim to make this list: Polaris. Almost Hyperspace: Random APOD Generator
