The Carina Nebula is home to the Keyhole Nebula and the active, unstable supergiant star called Eta Carinae. Visible from the Southern Hemisphere, it is located at the northwest corner of the Carina Nebula (NGC 3372), which resides in the constellation Carina. Located roughly 7,600 light-years away, NGC 3324 was first catalogued by James Dunlop in 1826. This period of very early star formation is difficult to capture because, for an individual star, it lasts only about 50,000 to 100,000 years – but Webb’s extreme sensitivity and exquisite spatial resolution have chronicled this rare event. An unusual “arch” appears, looking like a bent-over cylinder.A “blow-out” erupts at the top-center of the ridge, spewing gas and dust into the interstellar medium.Protostellar jets and outflows, which appear in gold, shoot from dust-enshrouded, nascent stars.Bubbles and cavities are being blown by the intense radiation and stellar winds of newborn stars.

Dramatic pillars rise above the glowing wall of gas, resisting the blistering ultraviolet radiation from the young stars.

The “steam” that appears to rise from the celestial “mountains” is actually hot, ionized gas and hot dust streaming away from the nebula due to intense, ultraviolet radiation.

Several prominent features in this image are described below. NIRCam – with its crisp resolution and unparalleled sensitivity – unveils hundreds of previously hidden stars, and even numerous background galaxies. The high-energy radiation from these stars is sculpting the nebula’s wall by slowly eroding it away. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image. Captured in infrared light by the Near-Infrared Camera (NIRCam) on NASA’s James Webb Space Telescope, this image reveals previously obscured areas of star birth.Ĭalled the Cosmic Cliffs, the region is actually the edge of a gigantic, gaseous cavity within NGC 3324, roughly 7,600 light-years away. (3.45 + 0.2) x 2.8 = 10.What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region NGC 3324 in the Carina Nebula. The width of the wall is 3.40 m and height 2.80 m. And what is the total width of your wall? The number of rolls is now easy to calculate.

The calculation can then be checked as follows: If the height of your walls is between 2.70 and 2.80 m, you can be sure that the roll of wallpaper sized 10.05 x 0.53 cm will be enough for 3 strips. This interval must be respected and individual wallpaper strips fitted together for seamless continuation of the pattern. Round up Y to whole number and you have the required number of rolls.Īll operations must be calculated in the same units, ideally in meters.īy 'repeat' we mean a number that can be found on the label of wallpaper rolls as 'repeat' or 'rapport.' It indicates the length or the interval after which the wallpaper pattern repeats. Standard wallpaper rolls made n Europe have dimensions of 10.05 m x 0.53 m, which amounts to 5 m 2 (square meters).Ĭalculation still continues – dividing the surface area of the wall (X) by the surface of the wallpaper roll: X ÷ 5 = Y In that case, you will need a helper – the following formula: (width of the wall + repeat) x height wall = X m 2 But you want to be sure that you buy the correct amount also when shopping online. If you are purchasing it at the specialised store, the amount needed will be calculated for you by the professionals. Optional technologies make it possible to measure the audience of our website, to display personalized advertising on third-party sites based on your profile. The correct calculation of the amount of wallpaper you will need for your interior is a key issue.
