This is a bummer. A coronagraph blocks the light from a bright object like a star to see fainter stuff (like material it's forming from) around it. STIS was the last camera on Hubble that could do this, and I helped calibrate that coronagraph.

Recent images from our SPIDERS pathfinder instrument demonstrating the self-coherent camera--next generation tech for direct imaging of exoplanets!
We use a special coronagraph to interfere the starlight with itself, like a classic double slit experiment... [1/3]

Roman's second instrument is the coronagraph, which will allow direct imaging of exoplanets at angular distances of 0.15 to 1.5 arcseconds from their host star; the glare of the host star's light will be blocked by the coronagraph.

While I was at AAS I missed that the two ESA PROBA-3 spacecraft (coronagraph and occulter) separated from each other at 2300 UTC Jan 14. The occulter has now been cataloged as object 62258, as expected, while the coronagraph is 62256. Congrats to the ESA teams

What a beauty! This is comet C/2024 G3 (ATLAS) passing through the field of view of the LASCO C3 coronagraph.
It wasn't for certain whether it would survive it's closest approach to the sun on January 13th, but it did and delivered us a spectacular show!

Who doesn’t like a bit of stargazing? ✨ The coronagraph aboard ESA’s eclipse maker Proba-3 took its first image, capturing several stars in the Serpent Bearer constellation. @orb-ksb.bsky.social took care of the star field analysis 🔭

Wow! The latest STEREO-A COR2 coronagraph image shows an impressive CME leaving the Sun. ST-A is off to the west looking at the Sun, so Earth would actually be located to the left in this coronagraph. You can see a good portion of this CME is coming straight at us, with most of it going north...
