Einstein’s theory of special relativity gave us the speed limit of the Universe — that of light in a vacuum. But the absolute top speed of sound, through any medium, has been somewhat trickier to constrain.

It’s impossible to measure the speed of sound in every single material in existence, but scientists have now managed to pin down an upper limit based on fundamental constants, the universal parameters by which we understand the physics of the Universe.

That speed limit, according to the new calculations, is 36 kilometres per second (22 miles per second). That’s about twice the speed of sound travelling through diamond.

It looks like our food for the future will be bugs. A factory in France will grow bugs as a food source.

Enter the insects. Or, more appropriately in this case, enter Ÿnsect, the French company with big ambitions to help change the way the world eats. Ÿnsect raised $125 million in Series C funding in early 2019, and at the time already had $70 million worth of aggregated orders to fill. Now they’re building a bug-farming plant to churn out tiny critters in record numbers.

You’ve probably heard of vertical farms in the context of plants; most existing vertical farms use LED lights and a precise mixture of nutrients and water to grow leafy greens or other produce indoors. They maximize the surface area used for growing by stacking several layers of plants on top of one another; the method may not make for as much space as outdoor fields have, but can yield a lot more than you might think.

A team of astronomers at the University of Hawaiʻi at Mānoa Institute for Astronomy (IfA) has produced the world’s largest three-dimensional astronomical imaging catalog of stars, galaxies and quasars. The team used data from UH’s Panoramic Survey Telescope and Rapid Response System or Pan-STARRS1 (PS1) on Haleakalā. The PS1 3π survey is the world’s largest deep multi-color optical survey, spanning three-quarters of the sky. IfA astronomers applied novel computational tools to the catalog, to decipher which of the 3 billion objects are stars, galaxies or quasars. For the galaxies, the software also derived estimates of their distances.

The resulting 3D catalog is now available as a high-level science product through the Mikulski Archive for Space Telescopes. It is approximately 300 GB in size, and science users can query the catalog through the MAST CasJobs SQL interface, or download the entire collection as a computer-readable table.

Revelations from NASA’s OSIRIS-REx probe are building excitement for its sampling expedition, slated to happen in the coming weeks.

Chinese has selected a third group of astronauts for the nation’s coming space station, the China Manned Space Agency announced on Oct. 1.

Great new podcast episode on our strange planet Mercury with planetary geophysicist Catherine Johnson, who eloquently explains what’s known about our tiny, innermost planet’s many remaining mysteries. Please have a listen.

Guest Catherine Johnson, a planetary geophysicist at the University of British Columbia in Vancouver, discusses this bizarre little world; the innermost planet in our solar system. A planet that’s so close to our Sun that its surface temperatures can hit 800 F. But surprisingly, its poles harbor enough water ice to completely bury a major metropolis. Some have even argued that Mercury may have once been habitable. Where it formed still remains a mystery, but it does have a tiny magnetic field, a very oversized iron core, and one of the largest impact basins in the solar system. A European mission is currently en route to orbit the planet in 2025.

The $9.8 billion observatory is scheduled to launch in October 2031.

NASA’s $9.8 billion James Webb Space Telescope has passed “environmental testing,” a series of trials designed to simulate the considerable rigors of launch, agency officials announced today (Oct. 6).

NASAs Transiting Exoplanet Survey Satellite (TESS) spent nearly a year imaging the northern sky in its search for worlds beyond our solar system. Explore this panorama to see what TESS has found so far.

Familiar stars shine, nebulae glow, and nearby galaxies tantalize in a new panorama of the northern sky assembled from 208 images from NASA’s Transiting Exoplanet Survey Satellite (TESS).

WASHINGTON — The United Arab Emirates plans to send a small rover to the moon in 2024, the latest step in the country’s growing space ambitions.

Sheikh Mohammed bin Rashid, vice president and ruler of Dubai, formally announced the Emirates Lunar Mission Sept. 29. That mission will place a small rover on the moon carrying several instruments that officials with the country’s space agency say will complement lunar missions by other nations.

“Primarily, we would like to advance our capabilities and technologies,” said Hamad Al Marzooqi, project manager for the Emirates Lunar Mission at the Mohammed Bin Rashid Space Centre, in an Oct. 5 interview. “Since we’re going to the moon, it would be a shame if we don’t do interesting science there.”
