Strategies to cure various types of blindness are looking more plausible after a series of recent breakthroughs using gene editing and gene therapy.
The launch of Hubble Space Telescope on April 24, 1990. This photo captures the first time that there were shuttles on both pad 39a and 39b.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
Can you be sure which pill is which? It can be difficult to tell if you’ve picked the correct medication.
The technology to identify pills is getting cheaper and smaller. That means it could also be used to test the make-up of illegal pills at festivals and other events.

There could be thousands of black holes at the heart of the Milky Way.
The Small Magellanic Cloud galaxy here seen in infrared light, but it looks different when viewed at other wavelengths.
The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.
Latent fingermarks dusted with micronised Egyptian blue on a $20 note, viewed in the Near Infrared.
The ancient Egyptians knew a thing or two about how to produce a vibrant blue pigment for their tombs and coffins. Now it’s being used to help find fingerprints.
