A rare freshwater reserve has been discovered underneath the sea off the coast of the South Island of New Zealand, which could help head off future droughts and mitigate the impact of climate change in the coming years.

The offshore freshened groundwater (OFG) was discovered through a combination of seismology and electromagnetic wave scanning techniques, which were used to build up a 3D map of the aquifer under the sea.

We think of spiral galaxies as being flat. You often hear the disk of our galaxy described as “flat as a pancake.” The large spiral galaxy next door – the Andromeda galaxy – looks flat through a telescope. But nature can be intricate, and, this week (February 4, 2019), astronomers made a surprising announcement. They said our home galaxy, the Milky Way, isn’t flat. Instead it’s warped and twisted.
