Sun rising on improved processing

Monday dawned clear and bright so we set up the hydrogen-alpha (Ha) solar telescope and recorded some image sequences. Today was a dull and cloudy day so we spent some time learning new processing techniques for our solar imaging and were rewarded with our best shot yet. The processing of choice was Solar Toolbox — a script package developed for use in PixInsight software — just the set of tools we were looking for! We’ve a long way to go but we think this picture shows great progress!

Woah! Really cool new videos from the Goode Solar Telescope at Big Bear Solar Observatory show timelapse adaptive optics views of the Sun's corona. This one is of a solar prominence being shaped by the Sun’s magnetism.

I like the choice to color hydrogen-alpha light pink.

You should check out all of the videos (the Sun is so fluffy!):

The solar surface just now in white light and calcium-k. Two interesting active regions rotating around to face Earth.

This image, taken by the VLT, shows two galaxies that appear to be interacting: the larger one is called NGC 3640 and the smaller one is NGC 3641. This pair of galaxies lies 88 million light-years from the Milky Way and is located in the direction of the constellation Leo. The image reveals a collection of.....

JWST won’t find the very first stars, but a new telescope can Although it's broken many cosmic records, JWST has yet to find the first stars, and probably never will. Here's why, plus what it'll take to actually get there. bigthink.com/starts-with-... #space #astronomy #JWST #science #physics

Just come back from a week of teaching people how to analyze Chandra data with CIAO.

The hardest part was coming up with fun questions for the post-lunch kahoot quiz!

Time warp

At the MPIA in Heidelberg @mpi_astro today, Nienke van der Marel describing the reference science case for protoplanetary disks with the METIS mid-infrared instrument being built for the 39-m diameter European Extremely Large Telescope

The diagram she’s using to illustrate the stages of star & planet formation was made 30 years ago

By me, when I was a staff member here at the MPIA
