These Two ‘Colliding’ Galaxies Make a Gorgeous Double Portrait

Just after we start to overlook in regards to the outdated Hubble Space Telescope, it comes again with one other wonderful have a look at the cosmos. It’s most up-to-date goal? Two spiral galaxies, greater than a billion light-years from Earth, that seem like colliding.

To be clear: They aren’t truly wherever close to one another, however from Hubble’s perspective, one is eclipsing the opposite. The galaxies are named SDSS J115331 and LEDA 2073461, and had been imaged by Hubble as a part of the Galaxy Zoo challenge, a citizen science challenge devoted to classifying the numerous galaxies within the observable universe.

A zoomable model of the picture might be seen here. Surrounding the galaxies you may see quite a few different gentle sources, primarily different galaxies.

The picture could not appear as crisp because the latest Webb Space Telescope pictures. Webb can see fainter gentle sources at higher resolutions than Hubble; one latest deep subject it took is made up of 690 particular person pictures that seize many extra galaxies than within the latest Hubble picture.

It’s not unusual for galaxies to overlap from our perspective. An early instance from Webb was its 150-million-pixel shot of Stephan’s Quintet, a bunch of 5 galaxies that seem to swirl collectively, although solely a few galaxies within the group are literally interacting with each other.

But Webb additionally sees completely different gentle than Hubble. Webb pictures principally within the infrared and near-infrared wavelengths—helpful for seeing historical, redshifted gentle. Hubble pictures principally in optical and ultraviolet wavelengths.

Hubble’s lengthy profession as an area observatory has hit a couple of stumbles these days. Several occasions in the previous few years, the telescope has been compelled into secure mode whereas engineers on Earth found out technical points with the spacecraft, which launched in 1991. But the telescope has staggered on.

Webb is extensively thought of Hubble’s successor, however because the veteran telescope reveals with this dazzling picture, it isn’t being changed. On the opposite, it has a singular manner of seeing our universe’s cosmic menagerie, and who’re we to show down such a feast for the eyes?
