Good morning, Rallypoint, and welcome to the August 14th edition of Astronomy PIcture of the Day (APOD): "4000 Exoplanets." How many exoplanets (planets outside of our Solar System) are there? According to the NASA website that tracks such data, that number now totals over 5,000.
Today's video clip (1:14) visually presents the history of exoplanet discovery since 1992. Researchers use four basic methods to detect an exoplanet: radial velocity (shown in pink), transit (shown in purple), microlensing (shown in green), and direct observation (shown in orange). The faster the calculated orbit of the exoplanet, the higher the tone. The area at the upper left highlight by the chord strike at 0:48 was the principle work of NASA's Kepler spacecraft, which was retired in 2018.

Incredible by any stretch of the imagination and these are only the ones we know about. So project that into infinity and the result has to be an ♾️ infantesmile incalculable amount.

One more thing on this Sir, thank you for a preview of infinity which you so remarkably bring forth in your infinite posts on what our journey on the way to Heaven might look like.

True, SSG Michael Noll. When I see things like today's APOD and then read John 10:16, I have to wonder if "we are alone" isn't a bit presumptive.

Maj William W. 'Bill' Price the shear number of KNOWN exoplanets by them selves tells me some, if not Many, may harbor life on them.... Maybe not as we know it, but life none the less.
