Descrizione Galaxy NGC 4214, pictured here in an image from the NASA/ESA Hubble Space Telescope’s newest camera, is an ideal location to study star formation and evolution. Dominating much of the galaxy is a huge glowing cloud of hydrogen gas in which new stars are being born. A heart-shaped hollow — possibly galaxy NGC 4214’s most eye-catching feature — can be seen at the center of this. Inside this cavity lies a large cluster of massive, young stars ranging in temperature from 10000 to 50000 degrees Celsius. Their strong stellar winds are responsible for the creation of this bubble. These features have the effect of stemming any further star formation due to the subsequent lack of gas.

È disponibile una miniatura di questa immagine in formato TIFF: File: NGC 4214.jpg.

The thumbnail version should be used when displaying the file from Commons, as the MediaWiki software is unable to create a thumbnail or preview of this file, because it is larger than 1000 megapixels.

Any edits to the image should be based on this TIFF version in order to prevent generational loss, and both versions should be updated.
