The Cynon Valley could see ambitious plans for a planetarium come to life if enough funding is sourced.
Back last year the group behind the plans said they remain "very optimistic" about the project going ahead, even though £40m of funding is needed to bring the vision to life.
It was in 2015 that Dark Sky Wales announced proposals to develop Planetarium Wales in Maerdy, Rhondda Cynon Taf, but at the time the site was described as being inappropriate.

Then, as time went on, the focus moved to the former Tower Colliery site in Hirwaun. If it happens the project would see the building of a planetarium at the site of the former coal mine.
It would be the second big attraction to open in the area with Zip World also having more recently opened its doors to visitors.
Allan Trow, of Dark Sky Wales, said the plans remain in "early stages" but confirmed they are now looking at securing funding to make the project come to life.
Mr Trow said: "At the moment it is still very much in the early stages. We have conducted a feasibility study with the help of Pen Y Cymoedd Wind Farm community fund, and are now seeking to establish an advisory board with the aim of securing funding.
"But as I stated, this is very early in the development of the planetarium."
Last year he told the BBC that it was issues around the ownership of the land that impacted on the original proposal in Maerdy.
"Tower [Colliery] is a totally different kettle of fish," he said.
"We have got the infrastructure in place, there is no issue about the ownership of the land.
"We're a lot more dependent on the funding than Zip World, but still - it's very exciting times."
Rhondda Cynon Taf County Borough Council said Dark Sky Wales’ project remains in the early stages, and formal plans are yet to be submitted.
None the less it has shown its support for the project's potential.
A spokesperson for Rhondda Cynon Taf Council said: “The proposed planetarium is an exciting prospect with the potential to add to the local tourism offer, and the council will continue to work with Dark Sky Wales at the appropriate stages of their ambitious scheme.”
