Merging Galaxies Bursting With Light - NGC 2207 and IC 2163

Just like our Milky Way galaxy, NGC 2207 and IC 2163 are sprinkled with many star systems known as X-ray binaries, which consist of a star in a tight orbit around either a neutron star or a stellar-mass black hole. The strong gravity of the neutron star or black hole pulls matter from the companion star. As this matter falls toward the neutron star or black hole, it is heated to millions of degrees and generates X-rays. These special objects are in a category of objects known as ultra-luminous X-ray sources (ULXs) and have been found using data from NASA’s Chandra X-ray Space Observatory. This Image is a mix of the optical and X-ray wavelength, with the optical showing the galaxies structure and the bursts of pink and purple representing concentrations of X-rays.

Subphylum Urochordata

Subphylum Urochordata (also called Tunicata) includes tunicates, salps, and larvaceans. This subphylum, along with subphylum Cephalochordata, is informally classified under protochordates. Protochordates are “primitive” chordates that are not vertebrates. Most adult tunicates are sessile and do not show chordate characteristics. However tunicates have a free-swimming larval stage that exhibits all chordate characteristics. Tunicates get their name from the outer covering, called a tunic, which cloaks their body.

The first two photos show pictures of tunicate larva. The next three photos show pictures of adult tunicates.
