25 years of exoplanet hunting hasn't revealed Earth 2.0 — but is that what we're looking for?

It's been a long ride for exoplanet science — and for Space.com itself.

I just came here to point out that i am pretty sure you got "Tess" wrong, in your article you state that it is 'Transiting Exoplanet Survey Telescope', when it actually stands for 'Transiting Exoplanet Survey Satellite'.

An interesting report. I note TESS info in it. "Though TESS has indeed identified some of those intriguing sort of Earth doppelgangers (again, depending on your definition), I would argue that its greatest discoveries are of the worlds that don't look like our home. The scary ones; the massive ones; ones similar to that diamond one that regrows its atmosphere like cockroaches grow heads and the one half-covered in lava like a parody of partial hell. To put TESS' own legacy into perspective, the exoplanet counter hit 4,000 in 2019, then hit 5,000 in 2020. One time, TESS data and Keck Observatory data caught 126 worlds in one go. Even citizen scientists have joined forces with TESS to unlock the next stage of what will one day be iconic exoplanet history and, every so often, TESS churns out a non-exoplanet discovery as well. See: Comet Burp."

The NASA archive sites shows all confirmed TESS, presently 491 today, https://exoplanetarchive.ipac.caltech.edu/index.html

MS descriptive stats show min a = 0.00622, max a = 1.152, TESS is finding exoplanets inside 1.2 au distance from the parent stars in the confirmed list. The mean size is near 5.8 earth radii (478 show earth radii size), so most are large exoplanets. This site is exploding now in exoplanet counts, https://exoplanet.eu/home/

I am still waiting to see confirmation in science that non-living matter evolved on exoplanets into life, eventually evolving into ET phoning home with abundant plant life too on ET home world

You are correct, that was certainly a blunder. Thank you for pointing this out.

This site shows 7020 confirmed exoplanets today, https://exoplanet.eu/home/

That is a bunch now for exoplanet studies. I note those listed with radii 1.1 or less earth size are 323 in the list. Min size 0.0000224 earth radii, max 1.098482 earth radii. Average size =0.88587 earth radii.

Average or mean mass = 16.117 earth masses. The min = 0.0603858 earth mass and max = 651.531 earth masses.
