This is a planet 8 times larger than Jupiter, but 11 times farther from its sun compared to the distance between Neptune and the sun.
Astronomers have revealed what appears to be the first image of a planet orbiting a sun similar to our own.
Astronomers from the University of Toronto using the Gemini North Telescope on Mount Mauna Kea in Hawaii imaged the young star 1RXS J160929.1-210524, found about 500 light-years from Earth and a body suspected to be a companion to that star. They were also able, through spectroscopic analysis, to confirm the nature of the companion, and it is a planet of eight Jupiter masses, and it is distant from its star at a distance 330 times the distance between the Earth and the Sun (the distance between the Earth and the Sun - about 150 million km, a single machine astronomical).
For comparison, the most distant planet in the Solar System, Neptune, orbits the Sun at a distance of about 30 AU. The parent star is similar in mass to the Sun, but is much younger. "This is the first time we have been able to directly see an object with the mass of a planet orbiting a star similar to our Sun" says David Lafrania, the lead researcher in the article detailing the discovery. "If we confirm that the object is indeed gravitationally bound to the star, it will be a big step forward."
Until now, the only planet-like bodies outside the solar system that have been directly imaged have been either floating alone in space and not orbiting a star, or orbiting brown dwarfs, which are dim stars that make it easier to detect companion objects with the mass of a planet.
The existence of a planet so far from the parent star also comes as a surprise, and poses a challenge to the theoretical models of stars and planet formation. "This discovery is another reminder of the great diversity of worlds in space, and suggests that nature may contain more than one mechanism that produces planets orbiting ordinary stars," says team member Ray Jayawardana.
The team is aided by Gemini's corrective optics that significantly reduce the interference caused by the Earth's atmosphere. The near-infrared images showing the new body as a planet indicate that this object is too cold to be a star and is not even large enough to be a brown dwarf.
Since there is always the possibility that this is a coincidental alignment of unrelated bodies, it will take another two years to confirm that the star and its companion are indeed moving in space together, but there are still enough clues for this, and of course this will require us to track the object, says Lafrania, who added that the group focused on the stars Young because most likely the planets surrounding them have not yet had time to cool and therefore will be easier to discover. The temperature on the surface of that planet is about 1,500 degrees Celsius, much higher than that of Jupiter (minus 110), while the parent star is a young star of type K7, which weighs about 85% of that of the Sun. "The discovery moves us forward to discover new surprises that nature holds," concludes Marten van Kerkoek, also a member of the group.

Separation fence, no entrance
to our Hogin
Why do you think I won't see you in the world? Is that why you made a separation fence without an opening?
If this is your goal, the riots in Ibilin will be nothing compared to the riots that the science responders will do to destroy your fences!
Besides, why do you think I don't know you??
Hugin - wife, two daughters, and age between twenty and sixty. Well, how many such women are there in our holy country, and even if you say that there are not a few, we have all the time in the world, after all, "this is the story of an eternity that will never end."
By the way, did I tell you that my little house is called... Eternity?
Shabbat Shalom and Blessed

A crow.. Uffffffffff...

Paternal affection - yes, without gain. And without any reservation - this is the love that does not have and has a name and a sunny heart and a real father
It really is true unconditional love, not that there is no judgment here and there, not that they don't say what is right
On the heart from time to time. But this is it. Simply this. Like my father who passed away not long ago and he is the head of the tribe of:
(Here above us, where he signed not long ago)
And he had a heart——like the sun that had just been born and more and more—the heart of an eternal emperor.
A staunch altruist without any conditions. You don't know me, and you don't really know me either. But for a while I will be, and we'll see how things will be completed. (even without you seeing me in the world).. You must not say such a thing...@@
Hugin on the website: This is the story of an eternity that never ends.
In any case, this is a historical picture. It's a shame they don't mention it in the media.
Dear Hugin
Happy
I told myself that the next response to you I will start with the title: "Dear Hugin",
Here is hope
Time 4:42, you felt the need to answer!
Well done!
Good day to the woman
Sabdarmish Yehuda
Yehuda
I am her
Hugin: In fairness
Night - good morning.
Dear Hugin'la Darlignati
Until a second ago I was focused on the words of our sages Michael and Magnivo.
It is not every day that we come across a debate in the "what did the poet mean" style.
But then I seized the market of my life, with strength and trembling I grasped your words that require a thorough analysis, an analysis that would put my "monsters" arguments in the shade.
Well....what did you mean by your words:- "Hugin: with the love of dear fathers"?
Fatherly love? Hugin?…you and I….fathers???
After all, everyone on the Internet knows that anyone can be whatever they want,
And I wonder if our Hugin is... maybe... Hog???,
Is she a single parent??
Not once but if one???.
Is Hugin the one and only that we loved to love so much, that we cried at her apologetic response, on whose shoulders we sobbed,...she...father...., not mother???
Is our Hugin Samson, not Delilah? Othello and not Desdemona?
Have dreams of female tassels faded and collapsed into the abyss of the dark mass?
And maybe we were wrong, maybe if we analyze the sentence differently, punctuate and add, here a period there a comma, we will reach a different, more optimistic understanding of your words?
For example,...perhaps...you meant "Hugin: with fondness for dear fathers."!!, Hugin likes fathers like me! A beautiful sentence, wonderful, happy, but...
But it can't be!, it requires two mistakes in one short sentence: adding B and adding L.
And not only that, when you wrote - "Hugin: in the love of dear fathers." You didn't leave any space between the word "hugin" and the word "lovingly", as if implying that you can't insert anything between them (except for two puny dots)
And maybe,... maybe I'm watching a historical moment, in which our Hugin, yes,,,, our Hugin comes out of the closet?... In your mind you're a mother, but you're a father!, is that the case?
And maybe it's a fluke that revealed to us that you are a mother who wants to be a father, who is jealous of Michael, Roy, me, Sabdarmish, and the rest of the stolen and cool commenters??
There are too many questions here and I have to reset myself.
In moments like these I miss my wife, real female tassels and not those of... maybe.
I will return alone to my cold bed
The moon has set
The brown dwarf from the article also cooled down and went out
Good night?
Sabdarmish Yehudit.
Judah
I'm looking for you in the sunshine, and you're hiding from me. Is everything okay??
Hugin: With the love of dear fathers.
Do you read the thoughts of the "monsters" that are so important, you too?? Darling.
for cool:
Not true.
If they wanted to talk about the planet, they would not have mentioned the sun. They would simply write "a planet similar to ours was discovered" and if they wanted to emphasize that it meant a star in a different solar system than ours they would write "a planet similar to ours was discovered in a different solar system" or something similar.
The title, as it is worded, clearly talks about the sun being similar to ours.
I am not an infidel by claiming that there will be people who will interpret it differently (if I did I would be an infidel in the existence of the reactions I referred to) but in that the interpretation according to which the planet is similar to ours is correct.
Thanks Yehuda, I meant according to 8 from Tzedek.
And Michael, according to the Hebrew syntax, the sentence "for the first time a planet orbiting a sun similar to ours was photographed" is ambiguous because we don't know if a punctuation mark was accidentally missing.
If they wanted to say that the planet is like ours, they should have added a comma: "For the first time, a planet orbiting the sun, similar to ours, was photographed"
And if they wanted to say that the sun is the one that is similar to ours, they should have added a verse of verse: "For the first time, a planet orbiting a sun similar to ours was photographed"
DA When will the Hubble telescope be replaced?
Michael and Svardamish Yehuda, convincing responses.
Some clarifications:
It says that a planet orbiting a sun similar to ours has been discovered.
The meaning here, according to the Hebrew syntax, is that the sun is similar to our sun - not a planet.
The novelty is that the star was photographed. Even in the past, much smaller planets were discovered, using other methods.
Astronomers look for any definable phenomenon in the sky and not just Earth-like planets.
It is written in the article that "a group focused on young stars because it is most likely that the planets surrounding them have not yet had time to cool" so why look for special explanations for the temperature?
to Nimrod and Ill
By no means am I disparaging astronomers!!!
Explain my words again.
When it comes to photographing a planet, it is one that reflects its sunlight. This light is about a millionth of the light of its sun and it is swallowed by the abundant light of its sun, so that from a distance of light years it is still impossible to photograph such a planet. To this day, the discovery of the planets in other stars is done by indirect means such as gravity, eclipse, spectrum, but not through actual photography and sight.
The title of the article: "For the first time a planet orbiting the sun similar to ours was photographed", made me understand that it was as if they had photographed one like this, and this is not the case. Photographed in SA a brown dwarf or brown dwarf-like orbiting (perhaps) its sun, a nice achievement in its own right, but not one to be taken for granted.
Is a brown dwarf orbiting a star a planet or a binary star system? It's a matter of definition, but that's really not what the astronomers meant in their search for a picture of a planet.
So I was disappointed and I'm sorry if my disappointment sounds like disrespect because that's not the case.
So have a good day on our planet.
Sabdarmish Yehuda.
What does it have to do with spacecraft flight speeds? Would you like to fly to a star?? Say, are you normal? Either you'll burn, or you'll crush, or you'll go into orbit around it, and that's not so pleasant...
Does anyone know what if any developments are being made in spacecraft propulsion technology?
Are such developments expected and what are the methods used today?
(And what about the speeds they are talking about)
Many thanks in advance!
Sabdarmish Yehuda,
A disparaging and even condescending tone emerges from your words towards the astronomers. why?
It is permissible to cast doubts and make counterclaims against the astronomers' interpretation of discoveries. But it is also desirable to do so in this regard.
And I will side with Nimrod's words: to my understanding, their interpretation stemmed from the fact that it was a young planet, so that a planet would be hotter to one degree or another, compared to the same system if it were the age of our solar system.
To respond
You apparently mean according to 8 of Tzedek.
Good night
Sabdarmish Yehuda
A planet with a mass 8 times that of the Sun has enough gravity to create nuclear fusion on a small scale in its core. And this is provided that there is hydrogen in the core
Of course, this refers to pressure conditions that do not create conditions for fusion yet...
The heat does not have to come from nuclear fusion. In a planet with such a large mass, various forces operate, such as great pressure conditions, which can "produce" a lot of energy.
Sabradmish Yehuda,
Why does a temperature of 1500 degrees at a distance of 330 AU from its sun contradict the fact that it is a planet? It is not possible that a planet after a very short period of time is formed will reach such temperatures?
BEN-JAMINI-KS-K7? Looks good, doesn't it? Data: 330-fold / 8 Tzedek essays?
Hogin: In fairness to a silversmith (for the tribe of Binyamin-Beninin-for the supreme grace).
Maybe there is an identical planet somewhere or a star that contains life but what is the probability out of the probability that it exists that we will even find it. negligible.
And besides, what they grab is not a sun similar to ours, of which there are many in the universe, what they grab is a planet similar to ours.
What they discovered here is far from being a planet similar to ours.
Good Day
Sabdarmish Yehuda
Sorry, but 1500 degrees is 330 times away from its sun, so it's clear that it's its internal energy, so it's not a planet, but if it's a star that has a nuclear pair, it's certainly close to a small brown dwarf. What they see in the image is the light source of the dwarf and not the light reflection of its sun (as in a real planet).
If it really revolved around the sun in question (this is also not certain) then at most they can be seen as a system of double stars.
Good Day
Sabdarmish Yehuda
It's not our solar system, it's another solar system, it's 330 times farther from its sun than we are from our sun
It's amazing to think that there could be life there in the solar system
1500 degrees? This planet is not interesting. Immediately abandon and look for others.
