Its biggest weakness might be the assumption that the chemical composition of dwarf stars is the same in elliptical galaxies as in the Milky Way.
Their strange shapes are a far cry from the majestic spiral and elliptical galaxies we see today.
The brightest of the group are Spiral Galaxy M61 and Elliptical Galaxies M49 and M60 and these are very easy to spot at the front of Virgo between the stars Vindemiatrix and Rho.
At first glance, the M87 galaxy appears to be one of many elliptical galaxies in the constellation of Virgo.
There were the familiar spiral and elliptical galaxies and some irregular shapes previously recognized.
The long-standing theory has been that spiral galaxies merge with each other forming most of the elliptical galaxies in the Universe.
It's not entirely clear what quenches star formation in elliptical galaxies," admits Kenney.
The image showed the galaxy exhibiting traits seen both in spiral as well as elliptical galaxies - an unusual combination that scientists believe was caused by gravitational interactions between NGC 4388 and other galaxies in the Virgo Cluster, which is estimated to contain over 1,300 members.
In addition, S0 galaxies do not have spiral arms that are as defined as the ones found in spiral galaxies, making them easily confused with elliptical galaxies when observed from the same angle that IC 335 is observed from.
