Question: What system of two galaxies had its discovery announced on a television program presented by Brian Cox and others?
Context: 9Spitch, officially designated ASW0009io9, is a gravitationally lensed system of two galaxies.  The nearer galaxy is approximately 2 e9ly from Earth, while the lensed galaxy is 10 e9ly distant.  It was discovered in January 2014 by Zbigniew "Zbish" Chetnik, an amateur astronomer from Northamptonshire, England, while classifying images on the website Spacewarps.org.  The discovery was announced on the BBC television programme "Stargazing Live". NGC 2685 (also known as the Helix Galaxy) is a lenticular and polar ring Seyfert Type 2 galaxy in the constellation Ursa Major.  It is about 50,000 light-years across and about 42 million light-years away from Earth.  It is receding from Earth at 883 kilometers per second.  It is an object of great scientific interest, because polar-ring galaxies are very rare galaxies.  They are thought to form when two galaxies gravitationally interact with each other.  "The bizarre configuration could be caused by the chance capture of material from another galaxy by a disk galaxy, with the captured debris strung out in a rotating ring.  Still, observed properties of NGC 2685 suggest that the rotating ring structure is remarkably old and stable." NGC 3226 is a dwarf elliptical galaxy that is interacting with the spiral galaxy NGC 3227.  The two galaxies are one of several examples of a spiral with a dwarf elliptical companion that are listed in the "Atlas of Peculiar Galaxies".  Both galaxies may be found in the constellation Leo. NGC 6090 is a merging pair of spiral galaxies, 400 million light years from the Earth, in the constellation of Draco.  The cores of the two galaxies are around 10,000 light years apart from each other, meaning that the merger is likely at its intermediate stage.  Two large "tails", made of galactic material gravitationally ejected during the merger, have formed outside the main galaxies.  Newly formed stars can be seen in the overlapping area. Arp 104, also known as Keenan's system, is entry 104 in Halton Arp's Atlas of Peculiar Galaxies catalog for spiral galaxy NGC 5216 and globular galaxy NGC 5218.  The two galaxies are joined by a bridge of galactic material spanning 22 000 light years. Mayall's Object (also classified under the Atlas of Peculiar Galaxies as Arp 148) is the result of two colliding galaxies located 500 million light years away within the constellation of Ursa Major.  It was discovered by American astronomer Nicholas U. Mayall of the Lick Observatory on 13 March 1940, using the Crossley reflector.  When first discovered, Mayall's Object was described as a peculiar nebula, shaped like a question mark.  Originally theorized to represent a galaxy reacting with the intergalactic medium, it is now thought to represent the collision of two galaxies, resulting in a new object consisting of a ring-shaped galaxy with a tail emerging from it.  It is thought that the collision between the two galaxies created a shockwave that initially drew matter into the center which then formed the ring. NGC 3227 is an intermediate spiral galaxy that is interacting with the dwarf elliptical galaxy NGC 3226.  The two galaxies are one of several examples of a spiral with a dwarf elliptical companion that are listed in the "Atlas of Peculiar Galaxies".  Both galaxies may be found in the constellation Leo. Arp 240 is a pair of interacting spiral galaxy located in the constellation Virgo.  The two galaxies are listed together as "Arp 240" in the Atlas of Peculiar Galaxies.  The galaxy on the right is known as NGC 5257, while the galaxy on the left is known as NGC 5258.  Both galaxies are distorted by the gravitational interaction, and both are connected by a tidal bridge, as can be seen in images of these galaxies. NGC 2536 is a barred spiral galaxy with a prominent inner ring structure encircling the bar in the constellation Cancer that is interacting with NGC 2535.  The two galaxies are listed together in the Atlas of Peculiar Galaxies as an example of a spiral galaxy with a high surface brightness companion. Stargazing Live is a British live television programme on astronomy that has been broadcast yearly since its first broadcast on BBC Two in January 2011.  The series is primarily presented by scientist Brian Cox and comedian and amateur astronomer Dara Ó Briain with support from TV presenter and biochemist Liz Bonnin and astronomer Mark Thompson.  It is broadcast from Jodrell Bank Observatory and has featured live links from scientific facilities in Hawaii, South Africa, Norway and NASA.
