There may be multitudes of Earth-like planets sprinkled throughout the Milky Way galaxy, but they are not so easy to find. To date, only around a third of the over 4,000 exoplanets found and confirmed are rocky -- and most of those are within a few thousand light-years of Earth... So the announcement of a new rocky exoplanet is always exciting -- but this particular newly discovered rocky exoplanet is even more exciting yet... it's a whopping 24,722.65 light-years away from us -- which could make it the most distant Milky Way exoplanet discovered yet.
It's so distant, it's close to -- and might even be in -- the galactic bulge, the densely populated region in the centre of the galaxy...
Most of the exoplanets we know of have been detected using one of two methods. There's the transit method, which detects planets based in the regular, minuscule dips in starlight when an exoplanet passes in front of it; and there's the wobble method, which detects minuscule wobbling exerted on a star by the gravitational influence of an exoplanet.
But there's a third method, based on the predictions of general relativity: gravitational microlensing. Imagine two stars, one behind the other, and an observer (us) at some distance again. Rays of light from the rear star (the source) are slightly bent by the gravity of the closer star (the lens) as they pass by. This distorts and magnifies that source light -- hence, gravitational microlens...

Must be funding time at NASA. People who laugh at folks who believe in God, are breathless in their belief in aliens.
It’s only 25,000 light years away. We’ll just set spaceball 1 for ludicrous speed, and be there by supper.
Time to pack my bags, this is just the place I’ve been looking for to burn up that 4 weeks of vacation time. Do I need sunscreen?
The 2nd post takes 25,000 light years to scroll through.
Send Bernie Sanders...
You can do that in two parsecs!
I AM F****** IMPRESSED!
Yet another unimaginably uninhabitable exoplanet.
The sixth article is about the planet that shall not be named.
Democrats scramble to send them ballots...
Of course all kinks will nopt be available now, I suppose. I’ll try a couple.
I can remember some of our school books had quotations from scientists who said that there were canals on Mars, they seen them in their telescopes, obvious proof of civilization. And when man can build a space ship that can travel that far he might find life forms similar to us.
And now that they have gotten there, the are silent as an oyster about the complete absence of any life forms. Not a word about the face that what they thought were canals was but the planet’s topography.
Here we go again, the atheists are at it again, this time they are seeing “planets just like earth.” At least they haven’t claimed seeing canals there...yet.
Atheists grasp at anything they think will disprove God and the Bible.
“It’s so distant, it’s close to — and might even be in — the galactic bulge, the densely populated region in the centre of the galaxy...”
Not a very nice neighborhood, outside the Galactic Habitable Zone.
“set by high energy events such as supernova and gamma ray bursts, higher metallicity leading to orbital decay of planets, and gravitational perturbations of Oort cloud comets sufficient to cause frequent comet impacts... These events cause mass extinctions and perturb complex life.”

I prefer it here, thank you very much.
Great book filled with lots of hard science for those interested in this subject. I'm always open to recommendations.
correction:
Not a word about the fact that what they thought were canals was but the planet’s topography.
