"Ser o Parecer" served as the album's lead single and was released on September 18, 2006, and had the support of a CGI-assisted music video.

The release contains a two-minute sample of tracks that RBD would include in their English language debut, Rebels, which was put on sale on December 19, 2006.

Another cover track on the album, "Bésame sin miedo", is the Spanish language version of the song "Kiss Me Like You Mean It", by singer and actress Sara Paxton.

[8] For the cover artwork of the fan edition of the album, a picture from the previous photoshoot was used, which showed the group in front of a blue background with fuchsia-color details.

[14] On March 11, 2007, the album's second single, the title track "Celestial", was released in Mexico and the rest of Latin America.

On June 22, 2007, as a result of their successful performances in Spain, as part of the band's tour, in a unique concert in the Vicente Calderón Stadium in Madrid in front of 40,000 people, they recorded their third live album and live concert video, Hecho en España, where the group displayed their unique material and their command of the stage.

The reason given through RBD's website was that the group wanted to give their public a better show by performing songs from their then upcoming album Empezar Desde Cero, which would be released on November 20, 2007.

Jason Birchmeier from AllMusic gave the album a 3.5 out of 5 stars rating, and commented in his review that "producers Carlos Lara and Armando Ávila [...] stick with their winning formula and wind up with a few standout songs: "Tal Vez Después", "Ser O Parecer," and "Dame," which are front-loaded for a catchy kickoff to the album."

He added: "In the end, such a factory-line approach undoubtedly amounts to generic music, and indeed, Celestial isn't all that different from Nuestro Amor (however, the departure of songwriter Max di Carlo, who had written [the group's] initial hits, including their theme song "Rebelde", does differentiate this from their superior debut album).

But as with any heavily invested mass-marketed product, it generally pays off to give customers what they want and expect, and Celestial should indeed please the teen pop group's hemisphere-spanning fan base as well as the suits at EMI[...].

"[32] Joey Guerra from Amazon.com debated in his review: "It would be nice to compliment the group's maturity, but there's almost none on this plastic collection of pop pastries.

Catia Dechen, from the Terra Networks-affiliated Territorio da Música website, highlighted the group's success, and reviewed: "Celestial without a doubt reached the success in sales as [the band's] previous albums, as the group resulted in being all the rage with the teenage public of various countries as well as with the media, is charismatic and keeps in the new album their proven formula for conquest: Beautiful youths and a pop repertoire easy to digest.

In 2008, Keith Caulfield of Billboard magazine revealed that Celestial had sold a total of 498,000 copies in the United States since its release, according to Nielsen SoundScan.
