NASAs Transiting Exoplanet Survey Satellite (TESS) has found its first Earth-size planet, Space.com reports. The planet, called HD 21749c, orbits a star about 53 light-years from Earth, researchers write this week in The Astrophysical Journal Letters. The rocky HD 21749c circles its star at close range, completing a full orbit every 7.8 Earth days, suggesting to astronomers that it is probably too hot to sustain life. TESS also discovered another planet orbiting the same star that astronomers are calling a sub-Neptune after its closest analog in own solar system.

Packed my bags and leaving in the morning.
Last minute folks welcome.
So if you put a 7 year old in a spaceship, they arrive at the new planet at age 60, having spent their whole life in boring outer space?
I’ll pass.
But, all that scorched rock is free!
Send all the libs and moslems there....never to return.

I think we should start a page on TripAdvisor !
In just over twenty seven years, the technology and techniques used to spot exoplanets has improved to this point -- very impressive.
LOL
Sooo, this is supposed to give me hope?
“...completing a full orbit every 7.8 Earth days...”
I’m glad I don’t live there; I’d be almost 3000 years old.
Actually, assuming near speed of light, he would still be about 8-10 years old due to time slowing down for him. 60 years would have passed for us and another 60 for us when the child had returned at about age 11-12.

If one could instantly accelerate to the speed of light and instantly decelerate to zero, a person could visit the entire universe, aging only when they are not travelling. Of course, they would have to say goodbye forever to everyone at any site they visited.
Assuming the theory of relativity is correct, time doesn’t pass when you are travelling at the speed of light, so from your perspective, you would arrive at each destination at the same moment you left the last one.
It seems like just yesterday there was no proof of any planets outside the solar system, Mars had canals, and Jupiter only four moons. Plus, the jigsaw puzzle fit of the continents was just a coincidence. We’re come a long way, baby.
Another Earth? Don't think so. It's only a new Earth to Demonrats from hell.

It looks to be the Romulan home world.
Not to worry as in 2387 a supernova will destroy it and it’s 4.2 billion inhabitants.
