Could this be the first direct image of an exoplanet?

This is an older article from 2016, but I've never seen this image before and its significance, if confirmed, is amazing.

This could be one for the history books, the first ever direct image of a planet not in our solar system.

European Southern Observatory (ESO) officials say this could be the first star system discovered to have both a close-in exoplanet and another one that is far-out. “If it is confirmed that CVSO 30c orbits CVSO 30, this would be the first star system to host both a close-in exoplanet detected by the transit method and a far-out exoplanet detected by direct imaging,” ESO officials.

...or a streetlight.

How many generations would it take to get there?
1,200 light-years away

This is absolutely amazing.

It's making me kind of dizzy/lightheaded to attempt to comprehend how far away that is. We are so tiny & insignificant. Very cool.

Since a generation is the average amount of time a group of people are born and grow up, say about 30 years, and a light year is a measurement for distance, your joke makes no sense.

That's a led light

No, not the first ever. In fact not even close. The article states it is the first to be imaged that is both a) far away from its host star and also b) that host star has a second but closer planet that was detected by the transit method.
Here's a list of other directly imaged planets. The earliest on that list was imaged in 2004 ( article with picture).

I assumed "Direct imaging" in this instance was with no infrared filters, and just using visible light.
I could be wrong though.

Depends on how you travel. 1200 light years is extremely close compared with many other stars but extremely far away for us.
If you could get a ship going up to near light speed then time slows down for the travelers. Go fast enough and they could arrive within their own lifetimes. Hell they could go there and come back within their own lifetimes. But over 2400 years would have passed here on Earth.
It's the same effect as was shown in the movie "Interstellar" although there the effect was triggered by being deep in a powerful gravity well. Time dilation is experimentally verified to be real though.
Edit: One of several ways that it's been verified is to take a bunch of radioactive nuclei with a known and very short half-life. Use a particle accelerator to get them going very very fast. Measure their half life, which turns out to be much longer. The difference is as Einstein predicted.

Insane to think about.
Would not want to come back to earth 2000+years later. Probably not even 100 years later. No telling what kind of freaky shite would be going on by then.

It can actually be traveled instantly.

That's the star, the exoplanet is the small dot to the upper left of it.

What is an exoplanet

It's just a term to describe planets around stars other than our own.

The first such was Fomalhaut B in 2004.
