The Andromeda Galaxy also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 2.5 million light-years from Earth, and the nearest major galaxy to the Milky Way. It’s name stems from the area of the sky in which it appears, the constellation of Andromeda.

How do Earth’s Northern Lights form?⠀
Aurora Borealis, also known as the Northern Lights, are caused by electrically charged particles from the sun, which enter the Earth’s atmosphere and collide with gases such as oxygen and nitrogen. When the charged particles are blown towards the Earth by the solar wind, they are largely deflected by the Earth’s magnetic field. However, the Earth’s magnetic field is weaker at the poles and therefore some particles enter the Earth’s atmosphere and collide with gas particles. It has been found that in most instances northern and southern auroras are mirror-like images that occur at the same time, with similar shapes and colours.⠀
Auroras can appear in many vivid colours, although green is the most common. Auroras can also appear in many forms, from small patches of light that appear out of nowhere to streamers, arcs, rippling curtains or shooting rays that light up the sky with an incredible glow. Ny Ålesund, Svalbard constitutes an ideal platform for observing and investigating Aurora Borealis thanks to the scarcity of anthropogenic light sources and the dark polar night sky.⠀

River to Infinity
This astro shot is from maruia springs,
A nice little place near Lewis pass which has great mountain scenery, plenty of pure New Zealand forest and is only a few hours drive from Christchurch, its awesome.
There is a huge river nearby, which on a dark night, at the right time of the year, stretches onto the ornate galactic light of the milky way.

Whenever we are looking up at the night sky 🌌, we are seeing light 🌠🔭from galaxies from various distances and therefore different eras in our Universe's history ✨(unless you live in a city 😅). The Hubble Ultra Deep Field (HUDF) 🛰🚀contains as many as 10,000 galaxies 💫of all shapes, sizes, colors🌈, and ages. The nearest, larger, brighter, well-defined spiral 🌀and elliptical galaxies are about a billion light-years away😱🤯. The farthest, smallest, reddest galaxies, numbering about 100, are 13 BILLION‼️ light-years away🤭😮 and may be among the most distant known🤩👽. #galaxies@nasahubble#NASA#universe#astronomy
