The recent James Webb Space Telescope(JWST) guide camera’s test image looks really similar to Hubble’s deep fields, which are my favorite. I decided to take a long exposure to the same target to see what my telescope can see and compare it to JWST’s image. I found one really faint galaxy 26–32 million light-years away, and a cute planetary nebula called Abell 39, pause and see if you can find it in my image.

Signs are positive after an explosion during tests this week, but SpaceX still ‘need to inspect all the engines’ of their Starship first-stage booster.

Quite the inspirational week this one with the complete set of JWST First Images. Loads of Starship and Starbase news. Last week I mentioned that it was fire time for Starbase, and…WOW… I was not wrong there. SpaceX’s Starship Booster 7 has gone for repair after explosion. Falcon 9 launches for both Starlink and finally CRS-25. We also had the very first launch of Vega C. Rocket Lab firing off another Electron, and more. So enough of this intro. Let’s crack on with it!

A new language model similar in scale to GPT-3 is being made freely available and could help to democratise access to AI.

BLOOM (which stands for BigScience Large Open-science Open-access Multilingual Language Model) has been developed by 1,000 volunteer researchers from over 70 countries and 250 institutions, supported by ethicists, philosophers, and legal experts, in a collaboration called BigScience. The project, coordinated by New York-based startup Hugging Face, used funding from the French government.

The new AI took more than a year of planning and training, which included a final run of 117 days (11th March – 6th July) using the Jean Zay, one of Europe’s most powerful supercomputers, located in the south of Paris, France.

It’s one of NASA’s most expensive science projects. A combination of difficult engineering and mismanagement led to cost overruns and delays. Now it’s nearly a million miles from Earth, preparing to capture images of the first stars that formed over 13 billion years ago.

An international team of physicists has developed a new technique that allows researchers to study the interactions between neutrons inside of an atom. In their paper published in the journal Nature, the group describe their laser spectroscopy measurement technique and how it can be used.

It has been nearly 100 years since scientists discovered that inside of every atom are protons —which give atoms their atomic number —as well as neutrons. And despite much study of subatomic particles, scientists still do not know what sorts of interactions go on inside of an atom. In this new effort, the researchers modified laser spectroscopy measurement techniques to study such interactions.

In this new work, the researchers began by looking at elements with a magic number —those that have highly stable protons and neutrons—and wound up using indium-131, which has a magic number of neutrons, and also a proton hole, in which a nuclide has one fewer proton than a traditional magic number element. Indium-131 is, unfortunately, also notoriously unstable, which means that it only exists for a short time before breaking down—it tends to last for just 0.28 seconds.

Should the Fed make a 1-percentage-point hike at the July meeting, it would be the largest move since Paul Volcker was Fed chairman in the 1980s.

Lasers normally use mirrors to create laser light, but a new kind uses clumps of moving particles. The result is a laser that is more programmable and could generate extra-sharp visual displays.
