ASTRO is an eight member girl group produced by the label SL Entertainment.
The company is known for their popular soloist, BIU (Bang Yookyung) and 
boy group, AETHER. 

AETHER is a ten member boy group who made their debut in mid 2013. Their
debut song EXODUS placed #1 and had the largest album sale of the year.
And their popularity grew much more after the release of their 2014 comeback
SWING which they released in both Mandarin and Korean.
On January 5^th the group debuted their first sub unit, CAELUS which composed
of three members and debuted with My Answer. 

ASTRO will be making their debut this 2015. The girls will be divided into two 
groups. NYX and EOS.

NYX'll have a much more mature, darker and y concept. While EOS is more
of a versatile group — but will focus more on a more upbeat, fresh and "cute"
concept. They'll first release a mini album all together, Interstellar. And will soon after divide into two.
