Hubble Tuesdays: When Galaxies Collide

Despite the immensity of the universe, galaxies still collide or nearly collide with each other. When their sizes are disparate, as they approach, the larger one, due to its tremendous gravitational forces and larger mass will begin to distort the smaller, exerting immense tidal forces on its edges. In this image, the large galaxy on…

Hubble Tuesdays: Dust Bunnies

They are very difficult to clean up since they are so…

There are areas in some galaxies that have a large cluster of new stars forming, new suns being born. In this area of the Small Magellanic Cloud, a satellite galaxy to our Milky Way, a rash of infant stars is being born. This starburst region, the nebula NGC 346, alone contains more than 2,500 infant…

One of the beautiful things about the Hubble is its ability to capture images that show changes over time. Our universe is in constant motion and undergoing constant change. Some of those changes are revealing, much as pictures of an individual over time show how much or little they change in response to age and…

Hubble Tuesdays: Grand Design

Some Hubble pictures are almost like looking at clouds, they take their shape from your imagination and it is possible to see things like giant sombreros and the eye of God. But some pictures are different. They are like peeking at the design of the universe, or at least one small part of it. Galaxy…
