The team realized they'd overextended their analogies and revised their press release to be more accurate: they developed a software tool to correct electronic distortions due to charge bleed within an infrared detector. It's good work! And JWST is awesome. www.sydney.edu.au/news-opinion...
How two Sydney students are sharpening the view from the James Webb Space Telescope
Two Sydney PhD students have found a fix to sharpen the images coming from a key instrument on board the James Webb Space Telescope. Louis Desdoigts and Max Charles are so thrilled, they got a tattoo ...

JUICE and 3I/ATLAS: An Unexpected Encounter in Space
3I/ATLAS, the third known interstellar object to date, is currently traveling through the Solar System and reached its closest point to the Sun yesterday.
In the next days, 3I/ATLAS is barely visible ...

After passing superior conjunction last week, interstellar comet 3I/ATLAS is once again observable from the ground with optical telescopes, now in morning twilight. Here's a view from the Lowell Disco...

I've been riding local DC/Baltimore transit regularly in recent weeks, and it is so darn painful I am ALMOST ready to go back to my car and just accept the horrible traffic. Yesterday I had 1-hour delays on both my outbound and inbound journeys. 😞

Okay - NOW I understand - the "spiral" is unrelated to the comet! It is a chance superposition of a glowing trail left by a meteor in Earth's atmosphere that happened to cross the sky in the same area that the distant comet appears. This image makes this clearer. star.ucl.ac.uk/~apod/apod/a...

Waitaminute you mean I don’t need to do any formal estate planning? 🤔
