Study proves ground-based telescopes can search for planets with two suns.
Astronomers have used a new technique to confirm a real-life Tatooine, the fictional planet with two suns that was home to Luke Skywalker in “Star Wars.”
The planet, Kepler-16b, is about 245 light years from Earth, is a gas giant, and is roughly the size of Saturn. Scientists already knew that the planet existed, but in a recent study, an international team of astronomers explained how they successfully applied a technique that hadn’t been previously used to observe a planet orbiting two stars.
“It’s a confirmation that our method works,” said David Martin, co-author of the study and NASA Sagan Fellow in The Ohio State University’s Department of Astronomy. “And it creates an opportunity for us to apply this method now to identify other systems like this.”
The technique, called the radial velocity method, has long been used in astronomy. (The first planet ever found around a sun-like star was found using radial velocity – and was found using the same telescope astronomers used to find this one.)
The radial velocity method involves analyzing the spectra of light produced by the stars. Astronomers gather spectra data through telescopes on the ground – in this case, from a telescope based in France, the Observatoire de Haute Provence. That spectra data graphs into a line, but the line “wobbles” as the planet orbits around the two stars, producing a shaky line in the spectra of light. The wobble indicates a planet is there, and astronomers can use it to derive a number of other pieces of information about a planet, including its mass.
Measuring radial velocity is, Martin said, among the best tools astronomers have to identify exoplanets, or planets outside our solar system. But until this study, astronomers had not been able to use it to find planets outside our solar system that orbit two stars.
The study was published this week in the Monthly Notices of the Royal Astronomical Society.
In the past, such planets – known as circumbinary planets – were identified by monitoring when one star passed in front of the other. That method, known as the “transit method,” has identified 14 such planets, including Kepler-16b. The first confirmed circumbinary planet was described in a paper in 2011; others have followed. But until this paper, none had been found using radial velocity.
“What people had faced was that having two sets of spectra from two stars makes it really tricky, and people were struggling to get enough precision to see the wobble caused by the planet,” Martin said. “And we got around that by making a survey of systems with two stars that orbit each other where one star is big, and one is quite small.”
The survey, called Binaries Escorted by Orbiting Planets, or BEBOP, was established specifically to search for planets like this one.
One of Kepler-16b’s stars is about two-thirds the mass of Earth’s sun, and the other is about 20% the mass.
Astronomers had been watching this system since July 2016.
Proving that measuring radial velocities can identify planets that orbit two stars, Martin said, opens the door for the technique to be applied more broadly. That is important to astronomers for a number of reasons, but a big one is that planets that orbit two stars tend to exist at a distance that would make them good candidates for life.
“These planets are frequently found in the habitable zone, at a distance from the stars where you would expect to find liquid water,” Martin said.
Kepler-16b, which is made primarily of gas, is not likely to be a candidate where life could be found, Martin said. But using the radial-velocity method could help astronomers find other similar planets.

Ping!..................
Sorry,
But this is total B.S.
No one has seen a planet around another Star.
In fact, the best we can see are stars, and they look like dots.
All we can see are their color.
No one has seen any features of any star...
Like it says, artist rendition...
Maybe star was is a documentary lol
Actually, you can google several pictures of exoplanets that have been photographed by Hubble.
The survey, called Binaries Escorted by Orbiting Planets, or BEBOP, was established specifically to search for planets like this one.
The next gen of the survey should be named BEBOP Deluxe.
Thanks Red Badger.
Looks like more bad news for flat Earth nitwits and other jagoffs.

Artist's rendition of stars, INTEL inside:
PINTELE Yid -- essential Jewishness:
...The little spark, the little point of purity, the Holy of Holies.
The littlest letter in the Hebrew alphabet is the Yud. It is a little dot. A small point. The pintele Yid is the pintele Yud. The numerical value of Yud is ten. Ten always connotes completion. In the decimal system when you go beyond nine, you go back to "one." You have gone back to the beginning, but on a higher level. Ten is an entire level higher.
The first Jew:
Gen 15
5. And he brought him outside, and said, Look now toward heaven, and count the stars, if you are able to count them; and he said to him, So shall your seed be:
6. And he believed in the Lord; and he counted it to him for righteousness:
Count the stars, if you are able to count them.
Can you count to 5 at least? Because "the stars" is ha-kokavim [הכוכבים]. The letter hei [ה] is the definite article "the". It's the letter with the value of 5.
Ha- kokavim *is* Five Stars = the best of the best of the best.
Everyone alive (in the present) knows the meaning, and Abraham's God is not the god of the dead but the God of the living.
Furthermore, one of the meanings of the letter hei is "here is", sourced from when Joseph said, "Here is [hei] seed for you." (Gen 47:23)
"Hey" you. Even the Japanese got the INTEL, because over here in the land named for its being the origin of the sun, under numerical substitutions is the info for 10:
Number -- 10
Kun'yomi readings -- tō, to, ta
On'yomi readings -- ju, ji
Transliterations from English readings -- ten[a]
Notes
a. The reading ten is more commonly achieved by reading the decimal point as ten (点), meaning "point".
5 can be read as "go".
The first Jew is ID'd at Gen 12:1, because the Lord said to Abram, "Go!", and he went.
When his name was changed to Abraham in chapter 17, the letter hei (= 5) was added. (Hei is seed for you.)
In fact, the best we can see are stars, and they look like dots.
5 also reads as "ko", which is a play on kō, a prefix meaning high, higher. An example is kō-gashitsu, "high image quality."
Also from the second link in this post (re the letter hei), the highest soul level:
Five also signifies the five levels of the soul: nefesh, ruach, neshamah, chayah and yechidah.12 The fifth tier, yechidah, means union. People commonly refer to this level of the soul as the pintele Yid, the G-dly spark that every Jew possesses. The pintele Yid is the spark that can never become contaminated or extinguished, the spark that unites every Jew with G-d.
Easy bet: Double or nothing he makes it.
"Ten is an entire level higher. "The survey, called Binaries Escorted by Orbiting Planets, or BEBOP, was established specifically to search for planets like this one.
Double prizes! ;)
P.S. "Ten!" in Hebrew [!תן] means "Give!" (masc. sing imper.)
Reminds me of this old time classic song about being 'neath the stars up above:
Buck made his first recordings in his own right for the small Pep label in 1956. His first release was Down On The Corner Of Love which was well-received locally, but due to poor distribution failed to sell in vast numbers. LINK
"Forget what you knew -- We'll start life anew, down on the corner of lo♥e."
I wonder how KIC 9832227 is doing these days.
PUN ALERT!...............
What instrument?
"Betelgeuse is usually the tenth-brightest star in the night sky"
https://en.wikipedia.org/wiki/Betelgeuse
Pun alert:
Bethel-Jews
But of course. ;)
Of course it goes on because Betelgeuse [ביטלג'וז] = 67 = Lev Yehudi [לב יהודי], a Jewish Heart.
Been a while since I was on the topic but as for character traits of the Patriarchs, Abraham is known for his loving kindness:
>>>
Each of the sefirot also corresponds to an archetypal soul. Loving-kindness as we all know corresponds to Abraham. In the Bible, we find the phrase: “loving-kindness to Abraham.”5 We also find that Abraham is described as “Abraham who loves Me [God].”6 So both the inner and external aspects are found explicitly in reference to Abraham.
That wasn’t the pun I was referring to, but I’ll take it!
Here’s clue:
Hayseed...............
Ancient Jewish writers were fond of puns.............In Hebrew, of course!.............
I was just adding to the pile. :)
A fun subject is the creation of Jewish surnames that came out of Europe, such as
Hebrew acronyms masquerading as words/names in the local language written in Yiddish.
Talk about multilingual punnage.
“Goetz” is so fun it even adapts into English + Hebrew, go + etz, a “go” tree.
It’s like Jacob’s ladder, reaching to the gates of heaven.
The rest of the Tatooine keyword.
Piano.
I arranged it for his grade level and he is doing a medley of Binary Sunset/ Imperial March/ and the Main Title.
I had him work out the segues in between the songs.
Albireo, also known as Beta Cygni, is the second-brightest star in the constellation Cygnus the Swan. At first glance, it doesn’t particularly stand out. But viewing this star through a small telescope can take your breath away...
Convert Albireo into Hebrew and you get אֱלֹ בְּעִיר O!
Convert back into English and you get City of God! And not just any city, Ayin Yud Reish means ‘capitol city!’
Ben Yehuda’s Hebrew English dictionary.
Cygnus, the swan… Under His wings you take refuge… What I call ‘hidden in plain sight’.
And for more fun the two stars of Albireo, blue and yellow, look at a candle flame.
New evidence that all stars are born in pairs
Which brings us back to the soulmates...
English is a Germanic language, and as such shares a lot of common words with German. Yiddish is also a Germanic language
with Hebrew, Aramaic and a touch of Latin mixed in and so will also share some of the concatenations.
So the field for pun makers is wide open..............................
Convert back into English and you get City of God! And not just any city, Ayin Yud Reish means ‘capitol city!’ Ben Yehuda’s Hebrew English dictionary.
Thanks for drawing attention to the star name.
To be clear on the meaning of "convert", these are puns. I found that Albireo is spelled as אלביראו, e.g. HERE. There are a few misc. differences in the end letters floating about, but nothing involving an ayin of course, but I wouldn't put it past Yiddish.
אל בעיר is "El" (or "L" the Latin letter) in the city , בעיר , ba-iyr
And ba-iyr would be a pun on a capitol city, which is a bira, בירה , the stress being on the second syllable.
By switching the stress to the first syllable, a capitol city becomes "beer": בירה
The fuller expression of capital city is iyr bira עיר בירה.
As in English, a capital city is a city, but not every city is a capital.
Or not every beer is really beer. I'll Root for the home team, in any case!
Ironic, too, about the name Albireo. It reads like it involved some type of drinking party.
