Despite being over twenty years old the Hubble Space Telescope still produces many of the finest astronomical images available.
This image of the magnificent NGC 2841 being no exception.

NGC 2841 is classed as a flocculent (fluffy) unbarred spiral and is located around 46 million light years from us here on Earth.
It is also a LINER – low-ionization nuclear emission-line region – a form of AGN typified by emission lines in ‘weakly (singly) ionised elements.
The galaxy was chosen by imaging as part of a new survey into star formation using Hubble’s Wide Field Camera 3. This is a new camera that was installed during the last servicing mission in May 2009.
The survey will look at a selection of galaxies and help to fill in the gaps in our knowledge of star formation across the universe.
NGC 2841 has been captured by an amateur astronomer in this beautiful image.
