Hubble (along with ground-based telescopes) revealed that the expansion rate of our universe is accelerating!
Soon, the Nancy Grace Roman Space Telescope will study the “dark energy” behind this expansion with its large field of view and infrared vision.
Its treasure trove of data will include tens of thousands of exploding stars and hundreds of millions of distant galaxies, tracing the universe’s expansion across nearly all of cosmic history!
Hubble's key observations led to dark energy's discovery (even helping earn a Nobel prize in physics!) and the mission will work with Roman to continue investigating this enigma.
As we gear up for its first images, we'll share more here on how Roman and Hubble bring different superpowers to astronomy. Check the link in our bio for more!

Hello again, M30!
This new image shows a globular star cluster, which is a roughly spherical grouping of stars held together by gravity.
Because of Hubble's long life, it's been able to observe M30 multiple times and track how different populations of stars in globular clusters move. Hubble can discern incredibly specific details in distant objects, allowing for this unprecedented "long-form" astronomy.

Image description: A star cluster seen up close, filling the view with thousands of stars. They are clearly divided between blue ones, which are scattered around the outskirts of the image but more towards the center and are the majority in the bright core of the cluster, and yellow stars, which are present in the core but make up most of the cluster outside of that. A few orange stars are closer to us and appear noticeably larger.

The ultimate group project: studying worlds beyond our own.
As we get closer to the first images from the Nancy Grace Roman Space Telescope, a long list of science objectives await.
One way Roman will team up with Hubble is by the different ways the missions will study exoplanets.
An exoplanet is a planet that orbits a star other than our Sun. Roman will likely find hundreds of thousands exoplanets with its remarkable instruments; meanwhile, Hubble’s capabilities allow for analysis of exoplanet atmospheres. This work is part of NASA's search for life elsewhere in the universe.
Plus, Roman's coronograph instrument will be able to directly image some larger exoplanets.
We'll share more here on how Roman and Hubble bring different superpowers to astronomy in the weeks to come. Check the link in our bio for more on Hubble and Roman!

Where's the oxygen?
After researchers studied 37 nearby dwarf galaxies, they realized much of the oxygen they expected to see was missing.
Oxygen is the main element formed by stars, and also the most abundant element after hydrogen and helium. But by using Hubble, these scientists learned that dwarf galaxies can only hang on to a small fraction of the oxygen made by stars.
Energy from the low-mass galaxies’ massive stars, along with galactic winds unleashed by supernova explosions, are apparently more effective at driving out the oxygen than current models predict.

Dark brown and milky white areas are also smudged throughout the center of the galaxy. The galaxy appears against a mostly black background lightly dotted with tiny white, blue, and red stars, and galaxies.

Happy Hubble Halloween!
This new image of the Cat's Head Nebula shows a star-forming region with an eerily feline resemblance.
The distinctive “cat’s head” shape of the nebula was likely sculpted over time by the intense ultraviolet radiation and winds from massive stars in the Carina Nebula, within which this nebula resides.
Dare to learn more at the link in our bio!
Image description: Visible-light image of the Cat’s Head Nebula by the Hubble Space Telescope. A dark brown, opaque filament of dust is in the center, stretching from the bottom to almost the very top. It has a narrow, irregular shape that resembles a cat sitting with its back toward the viewer and a tail extending downward. The cat’s head is turned toward the right, revealing a red glowing eye. The top half of the background is bright blue. Approximately halfway down, cutting diagonally across the frame, the background color changes from blue to yellow, orange, and finally red near the bottom. The image is dotted with many small stars. Some larger stars with the telescope’s characteristic four-point diffraction spikes are scattered in the background and foreground.

What’s that lurking just beyond the light of our own Sun? Something haunts the universe.
Gather ‘round the campfire for a tale of terror: a planet that never existed at all.
Happy Halloween!

Beware… space cat! 🐱
Something spooky lurks about 7,500 light-years away.
The watchful eyes of @NASAHubble and @NASAWebb unveiled the Cat’s Head Nebula, just in time for Halloween Eve.
This cosmic cat is in the process of forming new stars! Both telescopes captured this ghostly celestial object, formed by powerful stellar winds and radiation, in different wavelengths of light.
Find out more at the link in our bios… if you dare.

We’re not kitten around! @NASAHubble and @NASAWebb captured a purr-fect view of the Cat’s Head Nebula.
This long thin structure, made of dark, dense dust, looks like the head of a cat, its eye a newborn star still shrouded by the dust and gas from which it formed.
Hubble and Webb’s contrasting and complementary views give us a fuller picture of the features of this object. In the mid-infrared, as seen by Webb, the dust shines brightly while in the near-infrared, Webb can see through the dust to the stars hidden within. In visible light, Hubble's view shows a dark brown pillar of dust, with a yellow ridge along the right side. This bright rim shows gas illuminated and ionized by ultraviolet radiation from nearby massive stars. On the left are some dust pillars seen in the mid-infrared that are not observed in visible light.
It's paw-sible to "fly through" these views with the help of visualizations created by (human) data scientists, which bring Hubble and Webb observations to un-fur-gettable 3-D life. Happy Meow-lloween!

It's the honeymoon phase for these two galaxies.
Collectively called 2MASX J09133888-1019196, these galaxies are in the early stages of merging together, pulled in by their mutual gravitational attraction.
They form an ultra-luminous infrared system, which is rare for the early stages of an interaction. One possible explanation could be that one or both of the galaxies have already experienced a merger or interaction... but all relationships come with baggage!
Image description: The image focuses on two bright galaxies, at and above center, that are in the early stages of merging. More distant galaxies and stars dot the black background of space.

Skeletons don’t make puns. They don’t have the bones for it! But these telescopes do.
Check out some ‘boo’nus images of the skeletons of some of our favorite very undead telescopes, @NASAHubble, @NASAWebb, and Roman!
Image description: A collage of Webb, Hubble, Roman, and Chandra in cleanrooms during their assembly. Text across the middle of the collage is “Telescope Bones.”
@NASAHubble being assembled in the cleanroom at Lockheed Space and Missile Company in Sunnyvale, California. This view was taken after the shroud was placed over the Optical Telescope Assembly.
Image description: The body of the Hubble Space Telescope is placed vertically in a cleanroom with white walls. Two technicians in white protective jumpsuits stand beneath the telescope by a black railing.
@NASAWebb in the @NASAGoddard cleanroom in Nov. 2015 after engineers successfully completed two deployments for Webb’s “wings,” or side portions of the backplane structure that fold up. The backplane, often called the “spine” of the telescope makes up the carbon fiber framework which holds all 18 of the telescope’s mirrors.
Image description: The frame of the Webb telescope’s 18 segment primary mirror sitting up right in the clean room. Each mirror segment location has a round frame to hold it in place. Four technicians in white protective jumpsuits stand near the bottom of the structure, showing how large it is.
NASA’S Roman Space Telescope in the @NASAGoddard cleanroom in Dec. 2024 as the spacecraft went through its integrated payload assembly.
Roman will study dark energy, exoplanets, and more! The spacecraft is on its journey to its final orbit, completing critical milestones along the way. We expect first images by early 2027!
Image description: The Roman Space Telescope structure sits on a silver metal ridged ring in the NASA Goddard clean room. Large pieces of hardware that appear to be stacked on top of each other, together standing about three to four times taller than a person. The Roman Optical Telescope Assembly is on top, and resembles the tip of a dull pencil. Six black beams attach to a small circular object at the top and extend outward and down in a cone-shaped formation t
