ESA / Hubble & NASA, G. Piotto et al.
The term "globular cluster" alone does not create a vision of beauty, but real-life objects in space are among the most amazing Hubble space telescopes ever seen.
The European Space Agency described the globular cluster Messier 3, the subject of the recently released view of Hubble, as "one of the most beautiful of all." It is 8 billion years old and contains half a million stars.
The globular clusters are spherical collections of stars. However, Monsieur 3 is somewhat unusual. It is packed with a whole group of variable stars that change in brightness over time. Scientists have discovered 274 such hunters in Messier 3.
While we are casting around a cool cosmic term, here's another: "the blue is backward." These stars are more bluish and lighter than their brothers. They look younger than their neighbors, but they are really more like vampires.
ESA reported in 2009 that blue retarded can be formed by pumping fresh hydrogen from more massive stars.
"The new fuel supply allows the smaller star to heat up, becomes more bluish and hot ̵
1; behaves like a star at an earlier stage in its evolution," said ESA. In the Messier 3 Hubble image, you can see a bunch of these glowing blue whores.
Hubble was in a roll with space clusters. View the look of the telescope on an "open cluster", which is called the wild duck cluster . This is a completely different look from Messier 3, but also beautiful in its own right.
