"We're going to take our time before we draw scientific conclusions, but until then we can simply marvel at this celestial wonder," NASA's Scott Bolton said.
The galaxies are located hundreds of millions of light years away from Earth and are leaving a trail of stars and dust as they merge.
NASA still isn't sure what's wrong with the orbiting telescope, but engineers are being careful not to rush things, in case it leads to more issues.
The Hubble Space Telescope has been shut down since Sunday as a 1980s computer in the observatory navigates tech issues.
NASA has not said what sort of error has hit the Earth-orbiting telescope, but space fans hope it will be back online soon.
Two of Saturn's many moons, Mimas and Enceladus, can be seen in the Hubble image.
One suggestion is the star collapsed into a black hole without producing a supernova—a phenomenon that has never been identified in such a large star before.
"The flash was so powerful that it lit up the stream like a Christmas tree," said researcher Andrew Fox.
"Hubble has given us stunning insights about the universe, from nearby planets to the farthest galaxies we have seen so far," NASA's Thomas Zurbuchen said.
"I think you can make an argument that it's the greatest scientific instrument ever built," Mike Massimino told Newsweek.
These planets are roughly the size of Jupiter, however, they are around a hundred times lighter.
AM 2026-424 is the latest creepy cosmic image to be released ahead of Halloween.
The comet is only the second confirmed interstellar object to have passed through the solar system.
Researchers estimate that the explosion lasted for approximately 300,000 years.
The galaxies formed in the first two billion years after the Big Bang.
The exoplanet, dubbed WASP-121b, is located around 900 light-years from Earth.
The exploding star system is located around 7,500 light years away in the constellation Carina (The Ship's Keel.)
Messier 90 belongs to a vast collection of more than 1,200 galaxies known as the Virgo Cluster, which has a diameter of 15 million light-years.
These early stars may have blown up in a more violent and asymmetric fashion than previously thought.
It's confirmed: The universe is expanding 9 percent faster than expected.
The asteroid is located around 214 million miles from the Sun.
Pulsars are some of the strangest objects in the universe.
The cluster, around 4 billion light-years from Earth, contains hundreds of individual galaxies.
Nebulae are vast interstellar clouds of dust and gas.
The image features around 15,000 galaxies, the oldest of which dates back to 11 billion years ago.
The new technique will enable astronomers to study the properties of astronomical objects in much greater detail than was possible before.
