Researchers suggest how to make space telescopes cheaper and better

Posted by in categories: futurism, space

The JWST is just the beginning of a new era of space astronomy.

The James Webb Space Telescope (JWST) has been a spectacular success so far, revealing new insights into the cosmos with its powerful vision. But the JWST also has a history of cost overruns, delays, and near-cancellations that have raised questions about the feasibility of future space telescopes.

Answering AI’s biggest questions requires an interdisciplinary approach

Posted by in categories: Elon Musk, robotics/AI, space

When Elon Musk announced the team behind his new artificial intelligence company xAI last month, whose mission is reportedly to “understand the true nature of the universe,” it underscored the criticality of answering existential concerns about AI’s promise and peril.

Whether the newly formed company can actually align its behavior to reduce the potential risks of the technology, or whether it’s solely aiming to gain an edge over OpenAI, its formation does elevate important questions about how companies should actually respond to concerns about AI. Specifically:

Webb telescope spots star spewing bright supersonic jets

Posted by in category: space

The space observatory has observed a dynamic environment around a young protostar as it accumulates mass on its path to becoming a Sun-like celestial body.

Since its launch, the advanced James Webb Space Telescope.

One example is star-forming regions, often challenging to observe due to their location within densely populated clouds of gas and dust.

Earth’s health is depleting on six of nine parameters

Posted by in categories: health, space

Human intervention right now holds the key.

How do we assess the health of our planet? In 2009, a group of 28 scientists wanted a definite answer to this question. So, they outlined nine planetary boundaries, which are critical for Earth’s stability.

A reassessment in 2023 says that six of these nine planetary boundaries have been transgressed, suggesting that Earth is “well outside of the safe operating space for humanity.”

James Webb telescope stumbles onto signs of possible life on Earth-like planet

Posted by in category: space

(WTAJ) — Astronomers using the James Webb Space Telescope say they have stumbled onto possible signs of life coming from a massive Earth-like exoplanet, NASA confirmed in a release.

K2-18 b is an exoplanet — a planet outside our solar system — that’s 8.6 times as massive as Earth. A new investigation with the JWST revealed the presence of “carbon-bearing molecules” that include methane and carbon dioxide. The findings add to recent studies that suggest that K2-18 b could be a Hycean exoplanet, meaning it has the potential to hold a hydrogen-rich atmosphere and a water-covered surface, NASA reported.

Astronomers first studied K2-18 b’s atmosphere with NASA’s Hubble Space Telescope in 2019. The results prompted further studies of the massive exoplanet that have changed experts understanding of the system.

A new image from the European Southern Observatory (ESO) captures a cosmic wildflower in space.

Using the ESO’s Very Large Telescope (VLT), astronomers photographed a distant galaxy surrounded by what appear to be four light-blue flower petals.

NASA-inspired airless bicycle tires are now available for purchase

Posted by in category: space

Two years ago, we heard how the Ohio-based Smart Tire Company was developing shape memory airless bicycle tires. Well, the resulting Metl tires can now be purchased via – you guessed it – a Kickstarter campaign.

The never-go-flat tires were created in partnership with NASA, which had already applied the same technology to tires for its planetary rover vehicles … after all, it would be pretty difficult to fix a flat on the surface of the Moon or Mars. And no, they’re not literally airless. They’re hollow – so they have air in them – that air just isn’t pressurized, nor is it required for the tire to hold its shape.

At the heart of each Metl tire is a Slinky-like spring that runs all the way around the tire. That spring is made of a shape memory nickel-titanium alloy known as NiTinol, which is described as being strong like titanium yet also stretchy like rubber.
