NASA’s Hubble Space Telescope captures collision galaxies after recovering from a month-long mystery

The Hubble Space Telescope is back, and NASA has images to prove it.

The observatory went offline on June 13 and remained there for more than a month. Engineers struggled to identify a mysterious error. NASA has not yet announced the cause of the trouble, but the agency’s engineers on Thursday enabled some of their backup hardware to bring Hubble back online.
“I was very worried,” said Thomas Zarbochen, NASA’s associate administrator. Friday’s video interview With Nezanga Tool, who led it Hubble Team through troubleshooting. “We all knew it was more dangerous than usual.” Hubble slowly his strength science Over the weekend, we checked out the equipment and the system again to make sure everything was working. After that, when all this trouble started, he took the first pictures of it.

The telescope focused its lens on a set of unusual galaxies on Saturday. In a new image, a pair of galaxies are slowly colliding. The second image shows a spiral galaxy with long and extended arms. Most spiral galaxies also have a number of weapons, but only three.

After recovering from a month-long illness, Hubble’s first images show some unusual galaxies.

Hubble is also observing JupiterNorthern and southern lights, or auroras, as well as heavy clusters of stars. NASA has not yet shared photos from these observations.

NASA Administrator Bill Nelson said in a press release, “I’m glad to see that Hubble is looking at the universe and once again capturing the kind of images that have fascinated and inspired us for decades.” What is it.” “This is a moment for the team to successfully celebrate the mission’s dedicated success. Through their efforts, Hubble will continue its 32nd year of discovery, and we will learn from the observational transformation.” Will stay

A mysterious error that took a month to fix

The world’s most powerful space telescope, Hubble, was launched into orbit in 1990. It has photographed the births and deaths of stars, orbited new moons orbiting Pluto, and traced two interstellar objects zipping through our solar system. His observations immediately led astronomers to the Big Bang. Later galaxies are allowed to be viewed and the age and extent of the universe to be calculated. But the telescopic payload computer suddenly stopped working on June 13. Built in the 1980’s, the computer is similar to Hubble’s brain. It controls and monitors all science instruments on the spacecraft. Engineers tried and failed to bring it back online several times. Eventually, after running more diagnostic experiments, they realized that computers were not a problem at all.

It is not yet clear which piece of hardware was the culprit. Engineers suspect that a failed safe from the telescopic power control unit (PCU) ordered the payload computer to shut down. The PCU could send the wrong voltage to the computer, or the philosophy itself could go bad.

NASA was ready for such a thing. In case of failure of each piece of Hubble hardware, a twin is pre-installed on the telescope. So the engineers replaced all the defective parts in the backup hardware. The telescope is now in full inspection mode.

“I’m so excited and relieved,” Tool said after making the hardware switch. News Sharing

Although NASA has fixed the bug, it is a sign that Hubble’s age may begin to interfere with its science. The telescope has not been upgraded since 2009, and some of its hardware is more than 30 years old.

“It’s an old machine, and it’s like telling us: Look, I’m getting a little old here, okay? It’s talking to us,” Zarbuchin said Friday. “Even so, more science is ahead, and we’re excited about it.”
