I have found a galaxy closest to ours the Milky Way, and similar only ten times bigger. It is called J0107a. If you look at the skies at night at 12 pm, it is a little left for the moon, "Cetus". It is 11 million light years away.

The closest galaxy to the Milky Way is much closer than 11 M yr away.
J0107a sounds like part of a galaxy designation.
If this is a real galaxy (which you did not discover) then you can provide a link to the information about this galaxy.

So I`m thinking, since modern humans are 300,000 years old, aliens then have never even started the journey towards us after they for example picked up on our radio-signals.. If that is even possible with the distances in mind!

I don't know if life can exist anywhere else than in a galaxy similar to our own, but I assume intelligent life must have something similar.

Why are you talking about conditions for life in other galaxies. We can't see planets in other galaxies. We do know things about planets in our own galaxy.

Helg said:

Since again, J0107a is ten times bigger than ours, I was thinking maybe it has 2-3 planets like ours, not just one.

Based on what?

If they knew where we were here 300,000 years ago, then it's nothing compared to the 11 million light years it takes to travel here

I'm sure you meant at 12 am.

There are way too many variables (unknowns) right now for us to be able to accurately calculate how common, or not common, life like us (or more advanced than us) is right now, but a lot of scientists are working on it though.

As for life more advanced than us, while probably possible, even in our own galaxy, a lot of other questions (unknowns) come up also, like why we've never seen them, or heard from them, or had any contact with them/from them, and whatnot, etc, only furthering the problems in calculating how common or not common life like us (or more advanced than us) is, etc, I hope they find out more in my lifetime though, as it's most certainly a subject I am greatly interested in, but right now though, there's too many unknowns right now though, etc.

Might want to look into the Drake Equation if you've never heard of it, etc.

Also, I think the closest galaxy to ours is Andromeda that is on a collision course with ours soon, unless I'm mistaken about that, and I'm not sure how big, or how far away it is right now (but it's very, very easy to find out/look up, etc) and about it being on a collision course with ours "soon", I think it's four or five billion years or so, or something like that, so we've got some time before that happens, and our sun might make the earth uninhabitable before then, etc, but either way, a lot of this is still a long ways off still, so we've got some time still, time to evolve more and spread out from here maybe before that happens, etc.

As for how old homo-sapiens are, I think they are probably just as much approximately old as science says they are, or is, etc, but that Adam and Eve, and their very first descendants before a local flood wiped out most of them around 6-7 thousand years ago, were specially created/made by YHWH around that time, and were of what I have termed the homo-divinus species, around 11 to 12 feet tall, and perhaps having some more advanced knowledge than the homo-sapiens of that time (agriculture, building construction, metallurgy, advanced pottery-making, etc), and that started running into geographically and interbreeding with some of homo-sapiens that existed at that time, which is why most of them were wiped out by a localized flood at that time, and turned the once very lush middle-east into a desert due to some salt water being introduced at that time, and other things like that, etc. We're all hybrids now basically, or most of us are basically, etc. Still have some of that DNA/blood left, although it's not very much, and has been greatly diminished since that time, etc.

Anyway, God Bless.

One theory I like to throw out there is that maybe beings more advanced than us evolved to inhabit another plane of existence, or type of existence, which could be some of the reasons for the apparent absence maybe, and that maybe that will be our fate too eventually, but of course, I have no proof of that though, but it is an interesting theory though, etc. Maybe all advanced beings eventually evolve past this kind of existence, or transfer to another kind of existence, etc.

Or, IOW's, maybe we don't find a way to go faster than light travel, or wormholes we can find or make in space, or find other habitable planets we can get to/survive on/terraform before this other thing happens instead, etc.

And since we're now in the age of AI, maybe it's something both humans and AI learns to do together at some point in our both evolving, etc. Maybe we learn how to digitize our essences, or something similar to that, and learn to transfer them to something else, or something similar to that, etc.

God Bless.

There is another plane of existence.

And it is inhabited by beings more advanced than us.

But they didn't get there via evolution.

The word "universe" means "one verse."

And it's that one verse that announced the arrival of the universe.

Genesis 1:1 In the beginning God created the heaven and the earth.

So you "found" a galaxy in Cetus; are you a co-discoverer?

Funny you don't come across as Japanese, what is even more perplexing Japanese astronomers like any other astronomer would use a coordinate system like right ascension and declination to define its position, not "If you look at the skies at night at 12 pm, it is a little left for the moon, "Cetus"".
This doesn't make any sense even if it was 12am instead 12pm, furthermore it is 11 billion light years distant not 11 million.

Since this is a science forum here is the data.

I noticed in the J0107a data table in my previous post this, "Found (J0107a) behind the nearby galaxy VV114 in ALMA observations"
Now astronomers are clever people and have used gravitational lensing of foreground galaxies to aid in the discovery of fainter background galaxies.

I asked ChatGPT-5.5 if this was the case for J0107a.

No — not originally.

J0107a was found serendipitously in ALMA observations of VV114, meaning ALMA was pointed at the nearby merging galaxy VV114, and J0107a happened to appear in the background field. The discovery paper describes it as a distant CO-emitting galaxy behind VV114, detected by a strong emission line at 99.75 GHz, and says ALMA was sensitive enough to find such a source “even by chance.” (arXiv)

However, later work suggested J0107a is probably gravitationally magnified, with a possible magnification factor of μ ≳ 10. That means gravitational lensing may have made it appear brighter than it really is, but the object was not discovered as a planned gravitational-lensing target in the way some high-redshift galaxies are found behind known galaxy clusters. (arXiv)

Question	Answer
Was J0107a found in the direction of VV114?	Yes
Was it behind VV114?	Yes
Was it discovered by deliberately using VV114 as a gravitational lens?	No
Was gravitational lensing later suggested?	Yes
Likely effect of lensing	It may have boosted the observed brightness, perhaps by μ ≳ 10

So the clean wording is: J0107a was serendipitously found behind VV114; later evidence suggests it may be gravitationally magnified, but its discovery was not primarily a gravitational-lensing search.

The published discovery paper (2014) is here:


The discovery image made with ALMA (my favorite ground observatory) while targeting the object(s) VV114 they found a big bright source next to it:




The initial paper uses a CO (carbon monoxide) line to measure the redshift, but they couldn't be sure which line had redshifted to the observed frequency, so they had to use other data to make their best choice. It turned out to be correct when they had more data (z=2.467) in this 2021 paper:



The "J0107" was screaming out that it was a coordinate, but it seems way to short.

[For everyone else: The "J" is usually used in front of coordinates used in the J2000 coordinate epoch including when coordinates are used as names. The "0107" is the "1 07" of the lower axis (RA). If the second angle was used it would be "-1730". (ALMA) J0107-1730(a) would be a lot better name, but even then the patch of sky that it refers to is 2x larger on the vertical scale and 20x larger on the horizontal than this image.]

The 2023 paper has a JWST image of this thing:



(The galaxy in the center. The two lower galaxies are closer to us and not associated with "J0107a".

Further on the subject of gravitational lensing what is the most distant galaxy discovered and was gravitational lensing used?

The most distant confirmed galaxy currently known is JADES-GS-z14-0, although there is also a newer candidate called MoM-z14 that may slightly exceed it in distance if future observations continue to confirm the measurements. (Wikipedia)

For the confirmed record-holder:

• Galaxy: JADES-GS-z14-0
• Redshift: about (z \approx 14.18)–14.32
• Seen as it was: roughly 290–300 million years after the Big Bang
• Light travel time: about 13.4 billion years (Wikipedia)

The discovery was made mainly with the James Webb Space Telescope using its NIRCam and NIRSpec instruments. (Wikipedia)

As for gravitational lensing: no, JADES-GS-z14-0 was not discovered with the aid of strong gravitational lensing. It was found directly in a very deep JWST survey field (the JADES survey). In fact, one reason the discovery surprised astronomers is that the galaxy is intrinsically bright enough for JWST to detect without lensing magnification. (Wikipedia)

However, many earlier extremely distant galaxy discoveries did rely on gravitational lensing. Massive foreground galaxy clusters can act like natural cosmic telescopes, magnifying faint background galaxies. Examples include galaxies found in the Hubble Frontier Fields surveys. JWST’s sensitivity has reduced the need for lensing in some of the newest record-breaking discoveries.

It's possible we could colonize another planet in our solar system as another jumping off point for the future, probably Mars, but it of course doesn't naturally support life, so a lot of it might depend upon our technology in the future (we could also start treating this planet a whole lot better probably) (I know, novel idea, right?) Anyway, newer technologies could possibly save us as well maybe (as well as humanity becoming more mature maybe, etc) (again, I know, novel idea, right?) but what's also possible is that even if faster than light travel isn't possible, is that we could still make it to some different planets in other solar systems maybe, if we can find more hospitable planets there maybe, etc, they wouldn't have to be perfect, but just survivable, and our technology would probably be helping us probably, etc, but it would take a very long time for both the people and the crafts going there at sub-light travel, and would also come with a lot of risks every step of the way there probably, and after we do get there finally, but it is still possible maybe, etc. Right now there are still way, way too many unknowns with all of this really, especially when talking about some stuff (technology) that hasn't even been fully invented yet/thought of yet really, etc. Right now, our current level of technology probably isn't enough to do it right now probably, but the technology might not be that far off maybe, and might be right around the corner maybe, etc. So, for the future, I guess we'll have to see I guess really, etc.
