Astronomers made new discoveries that challenge some old notions about white dwarfs. Astronomers have used new data gathered by the Hubble Space Telescope to determine that white dwarfs may continue to burn hydrogen in the final stages of their lives. By burning hydrogen in the latter stages of their lives, white dwarfs may appear to be more youthful when viewed than they are.
Everyone was unsure if the iconic Hubble Space Telescope would ever get back to work for a long time. Hubble experienced a hardware failure that prevented the space telescope from conducting scientific operations. The good news is that NASA was eventually able to sort the problem and get the telescope back up and running normally.
Hubble regularly captures stunning images of the universe around us and sometimes NASA highlights photos that are particularly striking. That's the case with one of the latest images highlighted by the space agency, one that features three galaxies engaging in a galactic 'tug-of-war' battle. According to NASA, the galaxies are part of a 'peculiar' set.
The Royal Astronomical Society has introduced SuperBIT, a new balloon-based telescope that, it says, will fly to the verge edge of Earth's atmosphere to capture high-quality space images. SuperBIT is a joint effort between NASA, the Canadian Space Agency, Durham University, Princeton University, and the University of Toronto.
Hubble may only just have been fixed, but NASA is wasting no time putting the iconic space telescope back to work and sharing the latest images of distant galaxies. It was a nail-biting month of unexpected downtime for Hubble, after observations came to an abrupt halt in mid-June when the payload computer which manages the telescope shut down.
Hubble is back online and back examining the mysteries of the universe, with NASA confirming that its repairs last week have restored the iconic space telescope to scientific operations. After weeks offline, a potentially risky fix was attempted on Friday, July 16, with current and past Hubble team members stepping up to rescue the instrument.
The Hubble Space Telescope has successfully been switched to its backup hardware, with NASA's potentially risky fix for the ailing instrument seemingly working as planned. Hubble - which has been in operation for 31 years, giving scientists an unprecedented glimpse of distant galaxies - unexpectedly shut down in June, with the payload computer responsible for managing the telescope switching into its protective safe mode.
NASA will begin repairs on Hubble today, after the US space agency developed a new fix for the ailing space telescope. Scientific work with Hubble came to an abrupt halt midway through June, when the payload computer - responsible for managing the high-power telescope itself - unexpectedly shut down.
NASA's efforts to bring Hubble back to life and return the beleaguered space telescope to scientific operations continue, with a review of the next steps in the big fix completed. The long-running mission - which has seen Hubble gather unprecedented images of distant galaxies during its more than three decades of service - came to an unexpected halt in June, when the telescope's payload computer shut down.
The Hubble Space Telescope is currently not working due to a hardware failure NASA has been unable to repair. Despite its nonfunctional nature at this time, NASA is still sharing some of the beautiful images the iconic telescope has taken. One image can be seen below in cropped form, with the full image further down in the story. The image shows a pair of enormous galaxies that immediately capture your attention.
NASA's quest to repair the Hubble Space Telescope and restart scientific observations has had some good news, though efforts to fix the aging spacecraft still present some serious risks. More than three decades old now, Hubble unexpectedly went into its so-called safe mode in mid-June after the payload computer responsible for managing the telescope shut down.
NASA is in no hurry to repair the Hubble Space Telescope, all too aware that as the list of obvious candidates for the venerable instrument's unexpected shutdown shortens, the risks of permanent damage increase. It's been more than three weeks since Hubble abruptly went offline, the space telescope switching into safe mode and interrupting scientific research.
