The Biggest Telescope in the World is Half Built

Posted by in categories: space, sustainability

The European Southern Observatory continues to build the largest telescope in the world, the Extremely Large Telescope (ELT). Construction of the telescope began in 2014 with flattening the top of a mountain named Cerro Armazones in Chile’s Atacama Desert.

ESO just announced that progress on construction has crossed the 50% mark. The remaining work should take another five years. When it finally comes online in 2028, the telescope will have a 39-meter (128 ft) primary mirror of 798 hexagonal segments, making it the largest telescope in the world for visible and infrared light. The new telescope should help to answer some of the outstanding questions about our Universe, such as how the first stars and galaxies formed, and perhaps even be able to take direct images of extrasolar planets.

NASA’s James Webb Space Telescope Unveils 3D Visualization of 5,000 Galaxies

Posted by in categories: evolution, space

NASA’s James Webb Space Telescope has unveiled a stunning 3D visualization of 5,000 galaxies, providing a glimpse into the vast cosmic expanse.

The visualization, part of the Cosmic Evolution Early Release Science (CEERS) Survey, takes viewers on a journey through nearby galaxies to those in the far reaches of the universe, including one that has never been seen before by the telescope.

The Future Of AI—And Everything Else—Is Hybrid

Posted by in categories: robotics/AI, space

Qualcomm recently released a white paper titled, “The Future of AI is Hybrid.” In the paper, they outline a clear case that for AI to develop to its maximum capabilities, it needs to be processed both on the cloud and the edge. Computing at the edge would improve issues like cost, energy use, reliability, latency issues, privacy—all of the things that make scaling and growing a technology difficult. And they’re right: for AI to optimize fully, it needs more than one partner, more than one solution. But the greater lesson here is: that’s true for all technology moving forward.

When we hear the term “hybrid,” many of us think of hybrid cars—cars that run on both gasoline and electricity. We in the tech space eventually grabbed that term to refer to things like hybrid cloud —a situation where companies may process some of their data on the public cloud, private cloud, or data center in some type of mix. The goal in creating these hybrid models in technology was the same as it was with hybrid cars—to reduce energy consumption, improve costs, enhance performance.

The hybrid cars grew in popularity because they allowed users the enjoy the best qualities of both types of cars—gas and electric. Gas engines allow the hybrid to refuel quickly and move longer distances before needing fuel. The electric side helps cut emissions and save money. A similar concept is true for AI. AI needs somewhere powerful and stable for model training and inference, which require huge amounts of space for processing complex workloads. That’s where the cloud comes in. At the same time, AI also needs to happen fast. For it to be useful, it needs to process closer to where the action actually happens—the edge of a mobile device.

NASA’s MESSENGER spacecraft data reveals presence of chromium in Mercury’s core

Posted by in category: space

“Our model, based on laboratory experiments, confirms that the majority of chromium in Mercury is concentrated within its core.”

Mercury is the closest planet to the Sun, yet it is also the least understood. Mercury.

This odd planet features some of the most enduring mysteries, for instance, scientists aren’t sure where Mercury came from. How did its metallic core get so dense and big? Or how does this small planet, so near to the Sun, sustain even a thin atmosphere?

Beware the Digital Whiteboard

Posted by in category: space

In 2003, the data visualization expert Edward Tufte traced that year’s Columbia disaster—in which seven astronauts died when their shuttle disintegrated—to a piece of software. It was PowerPoint, he argued, that prevented people at NASA from understanding the gravity of the risks facing the shuttle. PowerPoint all but forced “breaking up narratives and data into … minimal fragments,” “a preoccupation with format not content,” and “a smirky commercialism that turns information into a sales pitch.” Serious dangers got buried at the bottom of a multilevel hierarchy of bullet points under a bigger, sunnier title. If only the information had been delivered in a proper technical report, Tufte implied, the astronauts might still be alive.

Twenty years later, there’s a new office tool keeping us from fully expressing and processing important information: the digital whiteboard. These boards are vast canvases on which you can add and drag around virtually limitless quantities of text, images, tables, diagrams, emoji, and shapes. In their typical state, they are mostly covered with sticky notes on which people have written a word or three. What the words signify in context can quickly become hard to remember, but that’s OK. Like books used as decorations, they get their value from the fact that they signify something.

Mystery Unveiled: Massive Granite Deposits on the Moon May Give Clues to Ancient Lunar Volcanoes

Posted by in category: space

A recent discovery shows that the moon’s far side was volcanically active. A team of geologists found a large granite deposit beneath a long-extinct lunar volcano, supporting the theory that the moon’s surface glowed with lava billions of years ago.

The lunar find was under Compton-Belkovich, a rumored volcanic structure on the moon’s surface. The feature is thought to have developed from the lava that cooled after fueling the violent eruptions of lunar volcanoes some 3.5 billion years ago, according to Space.com.

Although the discovery of volcanic leftovers in this area was not predicted, the study team was taken aback by the extent of the cooled magma patch. Its breadth is around 31 miles (50 kilometers) wide. This large mass of granite in the Compton-Belkovich volcanic complex may shed light on how the lunar crust formed early in the moon’s history.

‘Like a mirror’: Astronomers identify most reflective exoplanet

Posted by in category: space

A scorching hot world where metal clouds rain drops of titanium is the most reflective planet ever observed outside of our Solar System, astronomers said on Monday.

This strange world, which is more than 260 from Earth, reflects 80 percent of the light from its , according to new observations from Europe’s exoplanet-probing Cheops space telescope.
