That was originally assumed to be non-zero but very low. Modern planet hunting techniques have revised that number to be close to 100%. [1]

The Roman Coronagraph is designed to detect planets 100 million times fainter than their stars, which is 100 to 1,000 times better than existing space-based coronagraphs. The Roman Coronagraph will be capable of directly imaging reflected starlight from a planet akin to Jupiter in size, temperature, and distance from its parent star.

I appreciate that scientist are not always after the pretty pictures. They can be expensive, do not always give the data needed, and the experiments do not always produce data that has obvious pretty picture potential. Still, for the average non professional scientist (me) the pictures are about all I will ever get out of the science.

I always thought we would never be able to image something like that. The distances would be too small and the contrast too large to figure something at the resolution we can get on earth. I'll need to read up on how this was done.

The star in the middle of the animation, is approximately 20AU (Astronomical Units) in size looking at the scale line. 20AU is approximately 1.8b miles/3b kilometres or approximately the distance from the Sun to Uranus.
If Google's correct, if everyone on Earth lived on that star - each and every one of us could have a backyard larger than the surface area of Earth ;p

Their balanced position and simultaneous changes make them seem like an artifact of the imaging.

The creator of the GIF above used a data from a range of different telescopes and wavelengths, whereas I made this with using data only from same telescope (Keck), instrument, and wavelength (3.5 microns; near infrared).
