A NASA satellite is giving us our first full view of a brand new landmass.

Constant eruptions from an underwater volcano in the South Pacific Ocean starting in December created a new island, but ash obstructed aerial photography at first.

Months later, the Operational Land Imager on the Landsat 8 satellite was finally able to get a clear picture of the island, and the results are incredible.

Before the eruptions, the nearby islands of Hunga Tonga and Hunga Ha'apai were separated by over a mile of open ocean. But as of April 28, 2015, the two are almost fully connected, save for a few hundred meters. It's too far away to tell with the naked eye in the image above, but there's a gap between the new island and Hunga Tonga (in the upper right).

Unfortunately, the freshly-made island won't last for too long, scientists say.

Matt Watson, a professor at the University of Bristol, says the new land is unstable and vulnerable to waves and ocean currents.

"It's formed by fragmentation of magma, so it's basically small pieces of rock on top of each other that have formed an island," Watson told the BBC.

Despite the land's instability at the time that it first formed, Tonga resident GP Orbassano took a trip out to capture the photos below.

Orbassano walked around the island and saw its crater, and told NBC News that the earth was still hot weeks after solidifying in March.
