Hubble Space Telescope was launched on April 24, 1990, and entered service on May 20, 1990. Since then, it has observed all the planets in our Solar System, apart from Earth and Mercury. Earth is far better studied by geologists on the ground and specialized probes in orbit. Hubble can’t observe Mercury as it is […]

In January 2015, NASA released the largest image ever of the Andromeda galaxy, called the Panchromatic Hubble Andromeda Treasury (PHAT), taken by the Hubble telescope. This composite image involved thousands of observations, hundreds of fields, spanned about a third of the galaxy, and resolved over 100 million stars. Totaling 1.5 billion pixels and requiring 4.3 […]
The Giant Magellan Telescope (GMT) is a ground-based extremely large telescope under construction, planned for completion in 2025. When completed, it will be the world’s largest telescope and one member of the next class of giant ground-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed in the […]
