The first close-up picture of a star outside our own galaxy (eso.org)
This is an image of the star WOH G64, taken by the GRAVITY instrument on the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI). This is the first close-up picture of a star outside our own galaxy, the Milky Way. The star is located in the Large Magellanic Cloud, over 160 000 light-years away. The bright oval at the centre of this image is a dusty cocoon that enshrouds the star.

Cecilia Payne-Gaposchkin discovered that stars are mostly made of hydrogen (aps.org)
Have you ever wondered why stars shine? When you gaze up at the night sky and observe the twinkling shapes, or bask in the warmth of the sun on a hot afternoon, have you pondered the source of that light and heat? To start figuring it out, your first instinct might be to explore what a star is made of. However, doing so is hard, because stars are really *really* far away. Even our nearest star, the sun, is still really far away. Also, in the event you were able to travel through space and get close enough to touch a star, your spaceship would melt from the extreme heat (note: this is not an ideal situation for doing science).
