Though the james webb telescope East making headlines in Spain for the impressive images that it throwswe must not forget that there are other space telescopes, like the mythical Hubble, which is still active. Now, Hubble has achieved a spectacular new image of two galaxies in full interaction.
This is how he exposes it NASA on their website, showing the image of the one known as Arp-Madore 608-333. This photo shows a phenomenon involving two galaxies, which are enveloped in a gravitational interaction. According to NASA, these two galaxies they are “subtly warping” due to said interaction, interrupting and distorting them both.
The photograph was taken with the Advanced Camera for Surveys of the telescope or what is the same, the camera that it uses to carry out surveys. The idea, according to the agency, is to “create an archive of interesting targets for more detailed future study with Hubble” as well as other “ground-based telescopes.” There is no lack, either, the James Webb.
Two galaxies interacting
But how was this photo taken? Astronomers were forced to review the company’s astronomical catalogs for “a list of targets scattered throughout the night sky” to include objects already identified as interesting. Thus, they would be “easy for Hubble to observe no matter which way it was pointed.”
The problem lies in the time that Hubble has to observe these objects. “It is a long, competitive and difficult process,” they lament from NASA, revealing that these are assigned to get the most out of it, “down to the last second of Hubble’s available time,” so no easy task.
NASA details how there is a “small but persistent fraction of time” around 2 to 3% that becomes unusable when Hubble points to new targets. Snapshot programs like those captured by Arp-Madore 608-333 are designed precisely to fill that time gap, taking advantage of longer moments between observations.
This is where the image of the two galaxies interacting comes from. “Snapshot programs not only produce beautiful images, they allow astronomers to collect as much data as possible with Hubble,” the agency says.
