At the age of 21 years, the Hubble Space Telescope is celebrating its birthday with a close up image of a pair of interacting galaxies that together are called Arp 273. The smaller galaxy has shown so much affection to the larger one that a rose shape has formed.


During the birthday party for Hubble, Charles Bolden, who is the NASA administrator, stated, "For 21 years, Hubble has profoundly changed our view of the universe, allowing us to see deep into the past while opening our eyes to the majesty and wonders around us.'

And, 'I was privileged to pilot space shuttle Discovery as it deployed Hubble. After all this time, new Hubble images still inspire awe and are a testament to the extraordinary work of the many people behind the world's most famous observatory." [NASA: 'NASA's Hubble Celebrates 21st Anniversary with 'Rose' of Galaxies.'

The image of UGC 1810 and UGC 1813 - together called Arp 273 -- show a large spiral galaxy -- the first galaxy, UGC 1810 -- with a disk that is distorted in the shape of a 'rose' because of the gravitational pull of the small companion galaxy -- the second one, UGC 1813.

Blue points that look like jewels are found dancing across the top of the image. These jewels are really a bunch of bright, hot, young blue stars that are sending out enormous amounts of ultraviolet light.

As a perspective, Arp 273 is considered to be within the constellation Andromeda, and is located about 300 million light-years from our Solar System, well within the reach of Hubble to catch a peek at the two galaxies interacting.

The larger galaxy, UGC 1810 is about five times as massive as its smaller companion UGC 1813.
