“That is a highlight of this building that it’s very close to talent — people who are still in this area because they just graduated,” said Knight, The Engine Accelerator’s president and chief executive.

The Engine Accelerator is where companies solving hard problems get off the ground. It’s part coworking space, with open desks, office suites, and conference rooms for rent. It’s part startup accelerator, hosting a high-octane circle of young scientists and engineers who need help turning their ideas into full-fledged operations.

If WeWork and Y Combinator had a baby, and that baby wanted to bring breakthrough research out of the lab and into the real world, it’d look something like The Engine.

Whenever and wherever stars are born, which occurs whenever clouds of gas sufficiently collapse under their own gravity, they come in a wide variety of sizes, colors, temperatures, and masses. The largest, bluest, most massive stars contain the greatest amounts of nuclear fuel, but perhaps paradoxically, those stars are actually the shortest lived. The reason is straightforward: in any star’s core, where nuclear fusion occurs, it only occurs wherever temperatures exceed 4 million K, and the higher the temperature, the greater the rate of fusion.

So the most massive stars might have the most fuel available at the start, but that means they shine brightly as they burn through their fuel quickly. In particular, the hottest regions in the core will exhaust their fuel the fastest, leading the most massive stars to die the most quickly. The best method we have for measuring “How old is a collection of stars?” is to examine globular clusters, which form stars in isolation, often all at once, and then never again. By looking at the cooler, fainter stars that remain (and the lack of hotter, bluer, brighter, more massive stars), we can state with confidence that the Universe must be at least ~12.5–13.0 billion years old.

These could be incredibly valuable to future astronauts hoping to settle on the moon, acting as a convenient shelter for a lunar base.

The cave is accessible through a pit in the well-studied Mare Tranquillitatis (Sea of Tranquility). This is a large basin made mostly of basalt. Neil Armstrong and Buzz Aldrin touched down in this region on July 20 1969.

While Mare Tranquillitatis isn’t likely to be the first place humans try to settle on the moon, the existence of one cave makes the existence of others very likely, so scientists now expect there to be others in locations more suitable for human settlement.

A zigzag design can maximise how much heat walls radiate into space, while minimising heat absorption from the ground.

The moon’s glow meets a multicolored aurora in a new astronaut image from space.

International Space Station (ISS) and NASA astronaut Matthew Dominick, a veteran photographer of the Expedition 71 crew, captured the moon and auroras from his perch 250 miles (400 kilometers) above Earth.

A new study provides evidence that Mars contains a large ocean deep beneath its surface.

The finding is based on data collected by the InSight Lander, a robotic explorer operated by the American space agency NASA. InSight, which landed in 2018, was designed to capture data from within the planet’s interior. The lander ended its operations on Mars in late 2022.

For the current study, researchers used seismic data collected by InSight. The team examined the data to study Martian quake activity. Seismic activity on Mars happens in the form of “marsquakes.” NASA says InSight had recorded more than 1,300 marsquakes.

🎵🎶…Mars ain’t the kind of place to raise your kids…🎵🎶 Even then, since Mars has 38% of Earth’s gravity, it can only retain an atmosphere of about 0.38 bar.

These are some of the most compelling ideas on how to terraform Mars into a habitable, Earth-like world for future explorers.

A new theory suggests time travel might be possible without creating paradoxes.

TL;DR:

A physics student from the University of Queensland, Germain Tobar, has developed a groundbreaking theory that could make time travel possible without creating paradoxes. Tobar’s calculations suggest that space-time can adjust itself to avoid inconsistencies, meaning that even if a time traveler were to change the past, the universe would correct itself to prevent any disruptions to the timeline. This theory offers a new perspective on time loops and free will, aligning with Einstein’s predictions. While the math is sound, actual time travel remains a distant possibility.

Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.

Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.
