NASA’s Hubble Space Telescope photographed colliding galaxies after recovering from a month-long mystery glitch

LoadingSomething is loading. The Hubble Space Telescope is back, and NASA has the pictures to prove it.The Earth-orbiting observatory went offline on June 13 and stayed that way for more than a month while engineers struggled to identify a mysterious glitch. NASA still hasn't announced what exactly caused the problem, but the agency's engineers managed to br...

NASA’s risky maneuver to repair Hubble | Digital Trends Spanish

A team of NASA engineers has begun a major and risky maneuver to repair the Hubble space telescope, which stopped working in June of this year. According to those in charge, the problem could be related to the power control unit that supplies a constant voltage supply to the payload computer. For this reason, the engineers began this Thursday, July 15, to change their equipment to an alternative energy unit. Professionals have also indicated that this is a risky maneuver, which could return Hubble to its scientific observations in just a few days. "I think they are going to be successful, but that's not guaranteed," said Paul Hertz, director of NASA's astrophysics division. The telescope has been offline since June 13, when it unexpectedly stopped working. Since then, engineers have c...

NASA is about to switch its Hubble Space Telescope to backup hardware — a’risky’ maneuver to save its life

After a month of head-scratching, NASA engineers finally think they've identified the glitch that took out the world's most powerful space telescope more than a month ago.The Hubble Space Telescope, which launched into orbit in 1990, has captured images of the births and deaths of stars, discovered new moons around Pluto, and tracked two interstellar objects as they zipped through our solar system. Its observations have allowed astronomers to calculate the age and expansion of the universe and to peer at galaxies formed shortly after the Big Bang.But the telescope has been offline since June 13, when one of its main computers stopped working. NASA engineers have spent the last month running diagnostic tests and analyzing data...

NASA will attempt a’risky’ maneuver to fix its broken Hubble Space Telescope as early as next week

NASA's Hubble Space Telescope has been offline for nearly a month.The telescope's payload computer — a 1980s machine that controls and monitors all of the spacecraft's science instruments — suddenly stopped working on June 13. Engineers have been troubleshooting the problem since then, but with little success. However, a recent NASA announcement suggests a glimmer of hope: The agency tweeted on Thursday that it had successfully tested a procedure that would switch parts of the telescope's hardware to their back-up components.This could pave the way for the payload computer to come back online, leading to the restart of Hubble's scientific observations. NASA reported the pro...

Why was the Hubble computer in safe mode? | Digital Trends Spanish

A computer failure is the one that caused a setback in the hubble space telescope on June 13. According to NASA, the payload computer suffered a setback and had trouble accessing the backups. “Scientific instruments will remain in a safe mode state until the problem is resolved. The telescope itself and the scientific instruments remain in good health, "said the US Space Agency. The chronology of the POT indicates that on June 13 the computer stopped and on June 14 after trying to restart the computer, an error was caused that led to activate the safe mode. The payload computer is a NASA Standard Spacecraft Computer-1 (NSSC-1) system built in the 1980s that is housed in the Data Management and Scientific Instruments Command unit. The purpose of the computer is to control and coordina...

This asteroid “is worth” much more than the entire world economy | Digital Trends Spanish

Psyche is a strange asteroid that is 370 million kilometers from Earth. It is classified as one of the most massive in the main asteroid belt of the Solar System, which orbits between Mars and Jupiter. It is about 226 kilometers wide and unlike most asteroids, which are icy and rocky, Psyche appears to be metallic. Being so dense and metallic, it is thought that Psyche could be the leftover core of a planet that failed during its formation, which is known as a protoplanet. Thanks to observations made using the Hubble Space Telescope, astronomers have been able to get a clearer image of the asteroid. Hubble. "We have seen meteorites that are mostly metal, but Psyche could be unique in that it could be an asteroid that is entirely made of iron and nickel," explains researcher Tracy ...

Hubble Records Stunning New Image of Jupiter | Digital Trends Spanish

Thanks to the Hubble Space Telescope, it is possible to see a beautiful and clear image of Jupiter, when the planet was 653 million kilometers from Earth. The photograph was taken on August 25, 2020 and is useful for researchers to have an updated weather report of the dynamic atmosphere of the planet, as well as its icy moon, Europa, which can also be seen in the image. POT. At registry it is possible to perceive how in northern latitudes of Jupiter a bright white storm has begun to form, with an elongated shape that is moving at 560 kilometers per hour. Researchers believe that it could be a more durable spot in the northern hemisphere, different from the well-known Great Red Spot, which is found in the southern hemisphere of the planet and is one of its main characte...

Hubble Telescope: the most impressive images captured in its 30 years | Digital Trends Spanish

Hubble reached the milestone of 30 years in orbit in 2020, leaving us with the most incredible astronomical images ever captured, profoundly changed, incidentally, our understanding of the cosmos. Some of the telescope's most impressive images of space are well worth a look. This list, for now, goes from the photo celebrating 30 years of the space instrument to the one showing the Arp 273 group of galaxies. Cosmic Reef or Cosmic Reef (2020) NASA, ESA, and STScI This is the image that celebrates Hubble's 30 years in space: Cosmic Reef or Cosmic Reef, which refers to an underwater world. "It shows how massive, energetic, young stars light up and sculpt their birthplace with powerful winds and scorching ultraviolet radiation," according to NASA. Pictured are the giant re...

Look at the cosmic fireworks captured by Hubble | Digital Trends Spanish

They call it a Meathook for its irregular appearance: a broad base and a spiral much brighter than the other. It is scientifically known as galaxy NGC 2442 and has already been captured by the large astronomical telescopes on Earth, but this Monday the Hubble space telescope gave away one of the closest and sharpest images of Meathook, reported Digital trends. The galaxy is located about 50 million light years away, in the constellation Volans (Flying Fish) and is 75,000 light years across. According to astronomers at the European Southern Observatory (ESO), the distorted shape of the galaxy is most likely the result of a close encounter with a smaller and more hidden galaxy. In March 2015, Meathook was the site of a huge supernova - SN2015F - that glowed so long and ...

Identify the phenomenon that stole the shine from Betelgeuse | Digital Trends Spanish

In 2019, the giant star Betelgeuse unexpectedly began to dim in brightness, to the surprise of astronomers around the world. Astral bodies like her frequently undergo changes in their luminosity, but the drop to 40 percent of their usual brightness between October 2019 and April 2020 was rare. Its sudden darkening puzzled astronomers, who were quick to develop various theories to explain the abrupt change. The culprit was said to be a huge, cold, dark "starspot" that covered a wide area of ​​the visible surface. Some even thought that the star was about to explode and generate a supernova. But Hubble Space Telescope observations, led by Andrea Dupree, the associate director of the Harvard & Smithsonian Center for Astrophysics (CfA), Cambridge, Massachusetts, claim that ...
