NASA’s Hubble space telescope was launched on 24th April 1990. It was the first optical space telescope to be launched into orbit and has been one of the most productive scientific instruments ever built. It orbits the Earth every 95 minutes and has almost completed its 28th orbit of the Sun. So far in 2018 it has released a series of beautiful high resolution images and aided a number of scientific investigations which shall be reviewed.
Milky Way Bulge

The bulge of the Milky Way is a big, dense region of stars at the centre of our galaxy. Our Solar system is 26,000 light years away from the bulge in the disk of the Milky Way. The bright blue stars in the image are young hot stars in the disk between us and the bulge. The redder stars are the older more evolved giant stars with slow, scattered motions. The smaller white stars are younger and are more rapidly orbiting the galactic centre.
