A Satellite Accidentally Captured This Extremely Cool Photo of the Moon https://petapixel.com/2025/08/28/a-satellite-accidentally-captured-this-extremely-cool-photo-of-the-moon/ #CoronalMassEjection #coronagraph #earthshine #satellite #corona #Space #earth #moon #noaa #cme

Had the opportunity to visit a most fascinating solar #observatory Thursday in #Switzerland near #Arosa, the Astrophysikalisches Observatorium #Tschuggen (AOT) which #MaxWaldmeier had built in 1939, which was abandoned in 1980 and which amateur astronomers are now bringing back to the state just at that time: Here are the original Kern #coronagraph and another one from #Zeiss (with a huge spectrograph) it's sitting on.

Two European satellites mimic a total solar eclipse as scientists aim to study its corona.

The satellites have created the first artificial solar eclipse by flying in precise formation, providing hours of on-demand totality for scientists.

Dubbed Proba-3, the €181 million mission has generated 10 successful solar eclipses so far.

ESA released the eclipse pictures at the Paris Air Show on Monday.

Yay, 'live' images from the new solar #coronagraph CCOR-1 are finally available on https://testbed.spaceweather.gov/products/ccor-1-coronagraph though it is still not operational! Can we have another bright small-elongation comet now, please? ;-)

#JWST #Coronagraph discovered and photographed a NEW, MATURE #exoplanet , about 6x the mass of Jupiter and ~5-10º C in famous, nearby Epsilon Indi system, 12 light-years away!

MIRI is so sensitive, almost unfair 😱, the planet was visible in the VLT/NEAR data but unclaimed in Pathak et al. 2021

Next up, we’ve got Jason Wang about the #Roman #coronagraph.

Fun fact: Nancy Grace Roman envisioned imaging reflect light planets and wrote a paper about it. Jason points out how fitting it is that this will be done with Roman.

The Roman coronagraph will provide a large increase in sensitivity and demonstrate some key technologies: dark hole digging, large deformable mirrors, …#ExSSV

Absolutely awesome to see the Roman #Coronagraph Instrument getting integrated and tested @NASAJPL. Demonstrating technologies like wavefront control in space, it will allow us to image directly exoplanets like ~Jupiter in reflected light, starting in ~2027. Look at those optics!

Stars you see may have planets around them, but the starlight is so bright we can't see them even with powerful telescopes. Roman's Coronagrap…
