On April 24, 2015 Hubble Space Telescope turned 25. It has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics. It’s one of the largest and most versatile telescope, and is well known as both a vital research tool and a public relations boom for astronomy. I asked our panel what impact did it make on modern astronomy and what’s theirs favourite Hubble picture.

The Hubble Space Telescope is one of the most important scientific instruments ever created, and its benefit to modern astronomy is hard to measure. It has helped us discover extrasolar planets, search for icy objects at the very edge of the Solar System, and observe the most distant galaxies ever seen.
My favorite Hubble photo has got to be the Hubble Deep Field, which is an image of a tiny piece of the sky that Hubble stared at for dozens of hours. Every where you look there are just more and more galaxies – we truly live in an immense Universe.

Hubble has brought astronomy to the public’s attention like no other telescope. It has revealed our gorgeous and glorious Universe, raising the bar of what a telescope can do.
My favorite Hubble image is the “original” Hubble Deep Field — the image taken of an “empty” area of the sky about the size of a grain of sand held at arms length, but this deep view shows nearly 3,000 distant galaxies, evidence that our universe is filled with galaxies and that it’s bigger and more complex that we ever thought.
