Hubble releases beautiful photographs of


It’s official — NASA’s Hubble Space Telescope is again in motion after a pc anomaly all of a sudden shut down the 32-year-old system for a month. And in celebrating its comeback, Hubble launched two spectacular new photographs on Monday displaying the depths of the universe. 

Over the weekend, the telescope captured each a “rarely observed” pair of colliding galaxies, and a big “unusual” spiral galaxy, NASA introduced. The spiral galaxy captured has three arms, whereas most galaxies of that sort have a fair quantity.

The photographs had been captured as a part of a program on the University of Washington in Seattle.

On left, Hubble captured ARP-MADORE2115-273, a not often noticed instance of a pair of interacting galaxies within the southern hemisphere. On proper, Hubble captured ARP-MADORE0002-503, a big spiral galaxy with uncommon, prolonged spiral arms.

“I’m thrilled to see that Hubble has its eye back on the universe, once again capturing the kind of images that have intrigued and inspired us for decades,” NASA administrator Bill Nelson mentioned in an announcement. “This is a moment to celebrate the success of a team truly dedicated to the mission. Through their efforts, Hubble will continue its 32nd year of discovery, and we will continue to learn from the observatory’s transformational vision.”

The telescope has been on hiatus since June 13, when its payload pc all of a sudden stopped working. The failed sign mechanically put the telescope’s devices right into a secure mode, NASA mentioned, because it continued to orbit roughly 340 miles above Earth. 

Fixing the telescope was an all-hands-on-deck state of affairs, as NASA needed to name in retired workers members to contribute their information in regards to the equipment. Some of those that helped construct the telescope within the 1980s stepped in to assist resolve the pc drawback, whereas many others dove into paperwork which might be as a lot as 40 years outdated that might present perception on the malfunction. 

According to NASA, the issue was with telescope’s Power Control Unit, which helps present a “steady voltage supply” to the pc {hardware}. 

It took the efforts of greater than 50 individuals over the course of a bit of over 4 weeks, however on July 15 at 11:30 p.m. ET, NASA was in a position to get Hubble working as soon as once more, switching operations to its backup {hardware}. It began gathering knowledge simply two days later. 

Jim Jeletic, the deputy challenge supervisor of Hubble at NASA’s Goddard Space Flight Center, mentioned in an announcement that the advanced swap to the backup {hardware} required “15 hours of spacecraft commanding from the ground.”  

“The main computer had to be turned off, and a backup safe mode computer temporarily took over the spacecraft. Several boxes also had to be powered on that were never turned on before in space, and other hardware needed their interfaces switched,” Jeletic mentioned. “There was no reason to believe that all of this wouldn’t work, but it’s the team’s job to be nervous and think of everything that could go wrong and how we might compensate for it. The team meticulously planned and tested every small step on the ground to make sure they got it right.”

The final time Hubble needed to depend on backup {hardware} was in 2008. It’s pc unit was changed the next yr, and since then, it has taken greater than 600,000 observations, based on NASA. Since it was launched into area in 1990, the telescope has captured greater than 1.5 million photographs.
