Sharmila Kuthunur is a freelance science writer based in India. A computer engineer by profession, she found her love for astronomy in one of Carl Sagan's books - The Pale Blue Dot and has been hooked ever since. She has a fondness for old school astronomy and spends almost all of her free time either gazing up at the sky or reading about it. She is also the Contributor for Astronomy magazine since October 2017. She loves putting thoughts into words and talking about all things space.
Analysis of measurements via the Gaia space telescope – of star positions, brightnesses and distances – has let astronomers probe a merger 10 billion years ago between the primitive Milky Way and a dwarf galaxy called Gaia-Enceladus.
