...two teams, called UNITE (UNISTELLAR Network Investigating TESS Exoplanets) and Exoplanet Watch, have combined forces to confirm a new planetary discovery—a toasty "warm Jupiter."
...Planets around other stars, called exoplanets, sometimes block the light from the stars they orbit. When this happens, it's called a "transit." Amateur astronomers can observe exoplanet transits with their own telescopes by watching for the light from a nearby star to dim.
NASA's Transiting Exoplanet Survey Satellite (TESS) sees these dimming events, too—many thousands of them. But just seeing a star dim once is not enough. You need to catch multiple dimming events (and perform various other checks) to know that you've found a new exoplanet.
That's where volunteers from the UNITE and Exoplanet Watch projects come in...
These two teams of amateur astronomers have collaborated with the SETI Institute to detect the transit of an object called TIC 393818343 b (aka TOI 6883 b)—proving to the world that this object does indeed contain a planet orbiting a star.
First, the UNISTELLAR and SETI Institute team saw a single transit signal detected by the TESS space telescope. They gathered data to predict when the planet would transit again. They then alerted the UNITE and Exoplanet Watch amateurs to help observe the host star for signs of a transiting planet during the predicted time. The observations from the two networks showed two new transit detections, confirming the predictions, and demonstrating that a planet indeed causes the signals.

So now the twinkling of a star is really a planet orbiting it?
Lol
My understanding is that the twinkling of stars that we can observe directly is due to atmospheric conditions here on earth. When observing the alternation of dimming and brightening of a particular star over the course of months or years, it could be due to a transiting exoplanet between the earth and the observed star it orbits.
No. Twinkling is an atmospheric effect that doesn’t food anyone. A transit last far more than a second, and is witnessed by every observer. These people aren’t stupid. When you write as if they are, you come off seeming stupid.
Great work, guys,
“These people aren’t stupid. When you write as if they are, you come off seeming stupid.”
Trepanation….
Blood letting….
Global warming….
Global cooling….
Safe and effective….
Suddenly there was this giant explosion…
Shall we continue?
How many light years away?
Hmm, dunno. orbital “period of P = 16.24921 days, a mass M P = 4.34 ± 0.15 M J, and semimajor axis a = 0.1291 au... less than 0.15 au from its host star”

Ah.
“about 300 light-years away”

So it’s a brother by another mother?
Maybe a step-brother by a step-mother. :^)
These are the ones that are easier to detect because they are so close. The closer they are, the more impact their transit has on the light reaching us from the parent star.
We will head right over after we colonize Jupiter first.
I called SETI the....
Search for Extraterrestrial Idiots.
Why?
Because any plantetary civilization identifying their location for potentially hostile species (using radio signals) is really really stupid.
Oh wait—I know a species that does that...
Lol.
Isn’t it amazing (/sarc) that all these planet orbits perfectly line up with earth.
Thanks.
My pleasure.
