The Hubble Space Telescope is back at work after NASA fixed it last Friday. Now, the first photos of the Hubble telescope begin to arrive after the stoppage. Between his first goals they were “globular star clusters in other galaxies and auroras on the giant planet Jupiter,” NASA says in a press release. But they also had a look at some “strange” galaxies pending. And now that they have finally been observed, it can be said that Hubble has left us some incredible images.
“I confess I had some nervous moments during the Hubble shutdown, but I also had faith in the amazing engineers and technicians at NASA. Everyone is incredibly grateful, and we are excited to get back to science!” release Julianne Dalcanton, the researcher at the University of Washington in Seattle (United States) who wanted to study these two galaxies.

The galaxies photographed are the pair ARP-MADORE2115-273, can be seen from the southern hemisphere of our planet and are 297 million light years away. “Astronomers had previously thought that it was a ‘collision ring’ system due to the frontal merger of two galaxies,” explains NASA. But the new observations tell a different story. The Hubble photos “show that the ongoing interaction between galaxies is much more complex, leaving behind a rich web of stars and dusty gas, “they add.
On the other hand, ARP-MADORE0002-503 it is “a large spiral galaxy with unusual long spiral arms.” In addition, it is located about 490 million light years away. And its arms “extend to a radius of 163,000 light-years.” In fact, it is three times as large as the Milky Way. But it’s also curious because most disk galaxies have an even number of spiral arms, while this one does not. Has three.
NASA hopes that Hubble can continue working after the launch of the James Webb Space Telescope
The Hubble Telescope has been sending us photos for more than three decades and continues to do so despite the various fixes it has required. In addition, it has made more than 1.5 million observations of the universe and more than 18,000 scientific articles have been published with its data, as the US agency pointed out a few days ago. Moreover, NASA hopes that it can continue working after the launch of the James Webb space telescope; scheduled for the last quarter of this year. Perhaps it is possible that both can make one or more collaborations. We will see what happens. The good news is that NASA has not yet considered the idea of retiring the Hubble telescope. So we still have incredible images of space for a while.
