Even if the star has already collapsed and is now a stellar corpse that merged with a different galaxy, it's still was created when the observable universe was less than a billion years old.

If they were to use the same method (Event Horizon Telescope) of imaging, then the object would have to be a strong radio source. The region around the central black hole in our galaxy is about the size of our solar system and it had a radio signal strong enough to have been detected by equipment 90 years ago.

Then it could be a new star that has just begun fusion and making light, or it could be an old star that has run out of material and exploded as a superpower nova.

@josephfrank6815 You'd have to specify which galaxy and the dark matter content to know whether the expansion would be relevant. Spiral galaxies like our own and Andromeda didn't merge into the spiral form until a later time in the universe. There still could be spiral or irregular galaxies that formed earlier than the Milky Way and Andromeda and are still consistent with the expansion theory. The questions regarding the early creation of supermassive black holes, primordial black holes, and the first generation of massive stars are a bigger mystery. I'm not taking the position that the Big Bang Theory shouldn't be questioned. You should question all theories, but there hasn't been a noticable observation that contradicts the Big Bang.

There's a massive galaxy cluster and dark matter halo causing the gravitational lensing that's distorting the light. I would give a crude estimate of millions to billions years before we even notice something that large moves across our line of sight. It won't making a noticable position change within human lifespans. The interstellar asteroid that passed near the sun and now leaving our solar system is an example of the tens of thousands of years it would take something nearby to move.

No he didn't. Einstein was a theoretical physicist, Tesla wasn't.

It's the same in all directions. They locate a faint (deep field) galaxy in any direction to check to light spectrum, chemical composition, and red shift to estimate distance and age of the star. The star in this video had extra magnification from gravitational lensing that bends and distorts the light before JWST detects it. They use the red shift and survey of regional stars to calculate the effects of regular Hubble expansion and the accelerated expansion caused by dark energy.

I thought I was the only one who noticed the filthy title.

@josephfrank6815 Are you sure that you fully grasp the Big Bang Theory? It's not really relevant to new stars appearing to come from empty space.

@josephfrank6815 The reason why it's difficult to find observations inconsistent with General Relativity and the Big Bang Theory is because they're both well-tested theories of classical physics. There might be new particles we haven't identified, e.g., dark matter or the cause of accelerated expansion, but gravity, mechanics, thermodynamics, and conservations laws have been around for centuries and have changed little since Newton's laws of motion were introduced.

@josephfrank6815 Is your alternative explanation a static universe? That seemed like a reasonable explanation until the beginning of the 20th century. There were too many observations disproving a universe without expansion. The biggest evidence being Hubble's discovery of red-shifted light spectrum and the fact that Milky Way is only one of the billions of galaxies in the observable universe.

Hope the temperature and radiation inactivate all of those stowaway Covid-19 particles, but glad the telescope arrived at its new home.

No one asked.

I don't think Voyager probes emits enough thermal energy to be detected by JWTS. The telescope was designed to observe astronomical infrared sources. I'm not not sure whether or not the Voyager probes are still transmitting data as they leave the solar system.

The fifth grader that came up with this title should be grounded ASAP.

Image if we had an Isaac Newton who would dedicated his live to mathematic and physics.
