NASA Reveals "Hubble Bubble" for Space Telescope's 26th Anniversary
Hubble has been orbiting in space for 26 years today, capturing beautiful and often iconic imagery from all over our Solar System. Space imaging technology has come a long way in the last few decades, so for Hubble's birthday, NASA released comparison images of a celestial feature they describe as a "gigantic cosmic soap bubble."

Here's what the Bubble Nebula, which is located 8,000 light years from Earth in the Cassiopeia constellation, looked like to Hubble in 1998:

And here's the most recent picture of the nebula, which is not only presented in stunning detail, but also allows us to see the whole feature in a single image for the first time:

A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases, which often yields some of the best space imagery from the Hubble telescope. The nearly symmetrical "shell" surrounding the nebula is the result of stellar wind, a flow of gas ejected from the upper atmosphere of a star, which can be seen in the left of center of the image. The stellar wind from this star, which is twenty to thirty times the mass of the Sun, forces interstellar material outwards to form the bubble shape seen in the image.
