<p>NASA has released stunning dark images which show the movement of the trillion-tonne iceberg - one of the largest ever recorded - that recently broke off from Antarctica.<br /><br />As Antarctica remains shrouded in darkness during the Southern Hemisphere winter, NASA's Thermal Infrared Sensor (TIRS) on Landsat 8 satellite captured a new snap of the 5,800 square kilometre iceberg that split off from the Antarctic Peninsula's Larsen C ice shelf on July 10-12.<br /><br />The satellite imagery is a composite of Landsat 8 as it passed on July 14 and July 21 and shows that the main berg, A-68, has already lost several smaller pieces.<br /><br />The A-68 iceberg is being carried by currents northward out of its embayment on the Larsen C ice shelf.<br />The latest imagery also details a group of three small, not yet released icebergs at the north end of the embayment.<br /><br />The calving of the iceberg left the Larsen C Ice Shelf reduced in area by more than 12 per cent, and the landscape of the Antarctic Peninsula changed forever.<br /><br />Icebergs calve from Antarctica all the time, but because this one is particularly large, its path across the ocean needs to be monitored as it could pose a hazard to maritime traffic.</p>
