An asteroid wanders through this image of galaxy UGC 12158 captured by the Hubble Space Telescope. Hubble took multiple exposures of the galaxy, causing the foreground asteroid to appear as a series of bright white dashes. The curved path is due to parallax as Hubble orbits the Earth.
I came across this delightful video this afternoon when going through some old slides and paused what I was doing to watch the whole thing.
Here is a supercut of 18 astronomy visualizations from @spacetelescope, using computer simulations and Hubble images to create 3D flythroughs of objects in space.
I just love this image - it highlights why we need all the different telescopes: each of them looks at the same object in different ways. And only when working together a complete image emerges.
Here, #Euclid's wide field is combined with #Hubble's zoom-in and #JWST sharpest IR image we ever obtained, allowing us to study how radiation interacts with interstellar matter.

Millennial telescope tries to celebrate 34th birthday, but instead goes into safe mode because of gyroscope issues (relatable).
The same gyroscope that was causing issues back in November is acting up again, so Hubble has paused science operations while operators troubleshoot the issue. If needed, Hubble can operate with only one of its three remaining gyroscopes, with reduced observing efficiency.
#PPOD: In celebration of the 34th anniversary of the launch of NASA’s legendary Hubble Space Telescope, astronomers took a snapshot of the Little Dumbbell Nebula, also known as Messier 76, or M76, located 3,400 light-years away in the northern circumpolar constellation Perseus. The name 'Little Dumbbell' comes from its shape which is a two-lobed structure of colorful, mottled, glowing gases resembling a balloon that’s been pinched around a middle waist.

Launched on this day way back in 1990 aboard the Shuttle Discovery, giving humanity a remarkable window on to the awe-inspiring wonders of our universe, allowing us to witness even the stellar nurseries, birthplace of the stars themselves.
Happy Birthday #Hubble! It was launched #OTD April 24, 1990 on the Space Shuttle Discovery.
This year's anniversary image is of the Little Dumbbell Nebula, or M76.
M76 is a planetary nebula, a glowing cloud of gas ejected by a sun-like star at the end of its lifetime. The central bar structure is actually a ring seen edge-on. This was likely sculpted by a binary companion star. Two lobes extend from the bar to the left and right of the ring.
STS-31, the #SpaceShuttle mission that deployed the #Hubble Space Telescope, launched #OTD in 1990: April 24.
However, the astronauts didn't deploy the observatory until April 25.
My view -- which is not held by the good folks at STScI -- is that Hubble's birthday is thus the 25th; I liken it to April 24th is when Hubble's parents drove to the hospital / went into labor, but the 25th is when it was born. #Astrodon#HistoryOfAstronomy#NASA
What a show! To celebrate the 34th launch anniversary of the legendary #Hubble telescope, NASA is sharing its observation of the Little Dumbbell Nebula—an expanding double-sided bubble of glowing gasses from a dying star: https://bit.ly/3W2Kfw2
A behind the scenes look at the recent press release on finding asteroid trails in #Hubble's back catalog of images.
The first image is uncalibrated. Most of the dots and streaks are from cosmic rays, high-energy particles from space, hitting the detector. The long streaks running across the middle top of the image are from the asteroid.
The post explains the choices Visuals Developer Joe DePasquale made to get to the second full-color image that ran with the release.
Astronomers used #Hubble's unique capabilities to identify a largely unseen population of very small asteroids. The treasure hunt required perusing 37,000 Hubble images. The payoff? Finding 1,701 asteroid trails: https://bit.ly/4cYTBio
Improving the foundation of the cosmic distance ladder and reinforcing the possibility of physics beyond ΛCDM:

There is something seriously wrong with our understanding of the universe. Scientists using the James Webb and Hubble space telescopes have triple-checked and confirmed that depending on where we look, the universe is expanding at bafflingly different rates. Live Science explains more, including how scientists are ruling out a measurement error as the cause of the “Hubble Tension.” https://flip.it/VDvM6g #Science#Space#Hubble#HubbleTension#Universe#JWST
A #Hubble survey has found that brown dwarfs—objects smaller than stars but bigger than planets—live a lonely life as they age. Over time they lose the companion brown dwarf that was born alongside them as they drift their separate ways: https://bit.ly/43h3Mu5
The giant planet Jupiter, in all its banded glory, is revisited by #Hubble in images taken two months ago, capturing both sides of the planet. The many large storms and small white clouds are a hallmark of activity in Jupiter’s atmosphere: https://bit.ly/3V126mn
Reviewing the NASA budget proposal (all 800+ pages of it) and found this gem: “NASA is reviewing the results of the feasibility study performed with SpaceX and assessing potential next steps to boost the orbit and possibly enhance Hubble using private funding.”
