Hawaii’s Supreme Court suspends construction of the world’s largest optical telescope

Add as a preferred source on Google

Hawaii’s highest court has officially suspended construction of the world’s largest optical telescope atop the state’s sacred Mauna Kea volcano — a project that has been met with much opposition since it was first announced in 2009. Citing an improper issuing of the construction permit, the court halted the build to allow opponents of the telescope an opportunity to formally present their disputes. Though thirteen other telescopes call Mauna Kea home, native Hawaiians were reportedly unhappy about yet another telescope intruding on what’s considered holy.

Described in 2013 as “another important step forward for the future of astronomical discovery and economic opportunity” for Hawaii, the Thirty Meter Telescope (TMT) was poised to become the most advanced telescope in the world. Once built, the $1 billion TMT would not only have nine times the collecting area of typical optical telescopes, but would also boast the ability to observe objects and light from 13 billion years ago. Basically, this thing was going to be able to peer into our universe’s early years “finding answers to many of the grand challenges of science.”

For the TMT and its supporters (aka scientists), those days were about as good as it got. From the get go, activists and local groups frequently spoke out about the potentially negative impact construction of such a telescope would have on the surrounding environment. Moreover, many were uneasy at the prospect of damaging centuries of Hawaiian culture despite reassurances the project would exercise “responsible development and environmental stewardship of Mauna Kea.”

In the face of protest, construction of the telescope still managed to move forward. However, just this past April scores of protesters took to the build site and successfully halted its construction while activists took the fight to Hawaii’s high courts. After much deliberation, the courts ruled the permits awarded to the construction team were improperly issued, and called for an immediate production delay of the TMT.

“The Board of Land and Natural Resources issued the University of Hawai’i at Hilo a permit to construct a 180-foot astronomical observatory within a conservation district on Mauna Kea over objections of Native Hawaiians and others, who sought a contested case hearing to fully assess the effects of the project prior to making a decision of whether to issue the permit,” said Justice Richard Pollack in his concurring opinion. “The Board’s procedure of holding a contested case hearing after the permit has already been issued does not comply with our case of law…nor with due process under the Hawai’i Constitution.”

Though the project could still move forward after going through the required hearing processes, this is no doubt a massive win for TMT’s opponents. Contested cases could take years to sift through, and there’s also no guarantee construction permits will be reissued once the cases conclude. Despite tasting temporary defeat, TMT’s chair of the board Henry Yang gave his thanks for the court’s ruling, saying he respected the decision it made.

“We thank the Hawaii Supreme Court for the timely ruling and we respect their decision,” said Yang. “We are assessing our next steps on the way forward. We appreciate and thank the people of Hawaii and our supporters from these last eight-plus years.”

As of now, it’s unknown when Hawaiian courts plan on hearing contested cases, though the halt in construction almost certainly pushes the TMT’s operation date past the original estimation of 2024.

Space is becoming Bezos and Musk’s next data center site, and we have every reason to worry
The AI boom is coming for the night sky
How Vast's space station will look in orbit.

AI data centers already consume vast amounts of electricity and water on Earth, so Silicon Valley has begun looking somewhere considerably more spacious... literally.

Elon Musk's SpaceX and Jeff Bezos' Blue Origin, along with several other companies, have proposed enormous constellations of satellites designed to operate as orbital data centers. However, environmental groups and former space officials are now warning that putting them into orbit at the proposed scale could have severe consequences for Earth's atmosphere and the night sky.

The first possible exomoon is here, and it makes our Moon look hilariously tiny
Scientists may have found the first exomoon, except this one is the size of Jupiter
This artist’s concept depicts a potential volcanic moon between the exoplanet WASP-49 b, left, and its parent star. New evidence indicating that a massive sodium cloud observed near WASP-49 b is produced by neither the planet nor the star has prompted researchers to ask if its origin could be an exomoon.

We have already discovered more than 6,000 planets outside of our immediate neighborhood. Yet, finding a moon orbiting one of those distant worlds has proved considerably harder. Astronomers may finally have something close to the real deal, but this particular object stretches the word “moon” almost beyond recognition.

Using the European Southern Observatory’s Very Large Telescope in Chile, researchers detected strong evidence for a moon-like object in the CD-35 2722 system. Further observations are still necessary to confirm the discovery, but it could become the first confidently detected natural satellite outside our solar system. There is still one tiny complication though. This moon is apparently massive.

China’s answer to SpaceX’s reusable rockets literally catches boosters in a net
SpaceX catches boosters on legs. China just used a net.

SpaceX's playbook for recovering a rocket booster generally involves legs, a precisely controlled vertical landing, and either a concrete pad or a drone ship. 

China just managed to pull off something similar, but in a slightly different way, and on July 10, it tested the method as well.
