We know our universe is expanding.
But telescopes like Hubble measure an expansion rate that’s faster than predicted, based on models of the early universe.
Here’s how @NASARoman will join the quest on cracking the case of this “Hubble Tension” ⬇️

When you hear about the eerie side of the universe, it might make you feel a little "’stitious." @NASARoman will help shed light on some of these haunting sights.
Check out some scary space stories to tell in the dark:

It's the final countdown 🎶
We're one step closer to Roman's first images! The observatory is now fully functional and the team is performing their final checks and calibrations before starting science observations.

Did you catch the @NASARoman launch? 🚀
NASA’s newest space telescope is on the way to its home orbit a million miles away, where it’ll capture wide-field, infrared views of the universe!
Roman gets the big picture, while Hubble delivers the details. ⬇️

DYK that you’re moving at about 67,000 miles per hour right now?!
Earth is carrying you on its orbit around the Sun. When Roman launched, it inherited that motion and will undergo a series of maneuvers before its final orbital insertion at L2.

The Nancy Grace Roman Space Telescope has been named one of TIME's Best Inventions of 2026.
Roman continues its journey in space to its final orbit, completing critical milestones along the way. We expect first images by early 2027.

Roman’s marathon of testing continues while it zooms toward L2!
The team aligned and focused the telescope’s optics and gave Roman’s primary instrument a meticulous “eye” exam. The results: Roman’s cosmic surveys will be even sharper than expected! 🤩

What's in a wavelength?
Different "types" of light unveil different data about our universe. Hubble detects visible light, along with some near-infrared wavelengths that "cut through" clouds of gas and dust, as seen in this view of the Pillars of Creation ⬇️

A whisper, a hidden force, a secret holding the universe together. Meet dark matter, brought to you soon in even fresher detail by Roman. 🖤
The Roman team has been busy! Last week, they tested out the fine-guidance system, which keeps the observatory locked onto targets. Its current stability is like focusing a laser beam on a U.S. dime from ~150 miles away! They're working to improve this even further.

@NASARoman One way Roman will investigate dark matter is by tracking how smaller clumps of it warp light from more distant galaxies. These “gravitational lensing” surveys will enable scientists to fill in some gaps in our understanding of dark matter.

How does the universe work? Our @NASARoman is poised to help us answer this question by shedding light on dark matter, the invisible glue that holds the universe together. Dark matter makes up about 27% of the universe, but we still don’t know what it is. ⬇️

Hey!
ICYMI It's been almost a month since Roman's launch and the observatory is currently on its way to L2, a million miles from earth.

Sometimes your eyes need a minute to focus when you wake up. Roman's Wide Field Instrument just woke up for the first time EVER, and scientists have started adjusting its "eyes" so they can focus on the bigger picture.

Achievement unlocked!
Reward: More years of fuel!
We have completed Roman's first course correction so accurately that it conserved years of fuel for the mission!
