Animation captures the massive scale of what will be the world’s largest telescope

ESOcast 84: The New E-ELT Design Unveiled
The European Extremely Large Telescope is aptly named. The E-ELT will be the largest optical telescope on the Earth when it is completed in 2024. How big is big? A newly released concept animation video shows the massive scale of the telescope as it sits atop the summit of Cerro Armazones in Chile’s Atacama Desert.

The E-ELT is magnanimous both in hardware and finances. The telescope is several magnitudes larger than existing scopes that have primary mirrors measuring approximately 10 meters in diameter. In comparison, the E-ELT will have a primary reflecting mirror that is 39 meters wide and a protective outer dome that climbs 80 meters high. With all this extra hardware, the E-ELT reflecting telescope will be able to collect more light than all existing 10-meter telescopes combined, making it the most powerful ground telescope to date when it is finished. With its cutting-edge mirrors and adaptive optics technology, the E-ELT will produce outstanding images of our universe that are 15 times sharper than those recorded by the Hubble Telescope.

The telescope is being built through the efforts of the European Southern Observatory (ESO), a 16-nation intergovernmental research group focused on ground-based astronomy. The ESO currently operates some of the world’s largest and most advanced telescopes exploring the southern skies, including the Atacama Large Millimeter Array. The ALMA works in the millimeter and submillimeter wavelength ranges, providing crucial information about star and planet formations. The ALMA currently holds the title of the world’s largest ground-based astronomy project.

The ESO recently signed an agreement with Ace Consortium to build the E-ELT’s dome and structural framework, a $455 million dollar project that is the largest contract awarded by ESO and the largest ever in the history of ground-based astronomy. The mountaintop site for the telescope has been prepared, and ESO is now beginning the building and assembly stage, a process that will take up to eight years. The ESO expects to bring the E-ELT online sometime in 2024.

The Hubble Space Telescope is a beloved scientific institution, but at more than 20 years old it's getting rather long in the tooth. That's why NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) are joining forces to create the James Webb Space Telescope, a cutting-edge astronomy instrument that is set to launch later this year.

The Very Large Telescope spots a spooky skull nebula
Captured in astounding detail by ESO’s Very Large Telescope (VLT), the eerie Skull Nebula is showcased in this new image in beautiful pink and red tones. This planetary nebula, also known as NGC 246, is the first known to be associated with a pair of closely bound stars orbited by a third outer star.

Just in time for Halloween, the European Southern Observatory (ESO) has released an image of a spooky structure known as the Skull Nebula. This nebula, situated deep in the belly of The Whale constellation (Cetus), is located around 1,600 light-years from Earth. But the nebula is not only thematically appropriate for this weekend, but it is also notable for its unusual configuration of two closely bound stars being orbited by a third more distant star.

The Very Large Telescope captures a striking cosmic butterfly nebula
NGC 2899 planetary nebula

A beautiful image of an unusual planetary nebula has been captured by the European Southern Observatory (ESO)'s Very Large Telescope (VLT). The object, technically known as NGC 2899, is located between 3,000 and 6,500 light-years away in the constellation of Vela (the Sails) and has been imaged in detail for the first time, showing off its rare butterfly shape.

This highly detailed image of the fantastic NGC 2899 planetary nebula was captured using the FORS instrument on ESO’s Very Large Telescope in northern Chile. This object has never before been imaged in such striking detail, with even the faint outer edges of the planetary nebula glowing over the background stars. ESO
