NASA Webb Telescope engagement report
@NASAWebb - 3.5M followers on X
Measured over 5 original posts from a 30-day window, last computed on August 31, 2026.
Engagement
Early reading. We have captured 5 original posts for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 2.1K interactions against 3.5M followers, an engagement rate of 0.059%. Posts are seen about 122K times each, and 1.70% of those impressions turn into an interaction. That is about 3.48% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.53 post a day over the last 30 days, though only 20% of days saw any activity at all. Most posts go out around 15:00 UTC, and Tuesday is the busiest day of the week. Of the 5 posts sampled, 100% carry an image or video, 40% are part of a thread and 20% link out. The account's strongest tracked post pulled 5.1K interactions, about 2.4x its own typical post. Only 5 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 15:00 UTC, and Tuesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Amaze amaze amaze! Webb teamed up with @NASAHubble, observing the ringed planet in complementary wavelengths of light to give us a richer, more layered understanding of its atmosphere. https://t.co/RJrz4Xd6Qw https://t.co/6ivoSELu6S

Don’t let anyone dull your shine 💫 The heart of galaxy M77 nearly outshines the galaxy itself in this mid-infrared Webb image. Gas rapidly orbits the central black hole, heating up, and radiating light. https://t.co/LDOGmXEytb https://t.co/uUnT4cb7v9

It's the circle of life… Webb's look at the Lion Nebula, the remains of a dying lower-mass star, is in both the mid and near-infrared. Though massive stars undergo supernova explosions at the end of their lives, lower-mass stars shed their outer layers. https://t.co/9dmHxUlHio

Webb captured this new image of galaxy Messier 58, in both the near and mid-infrared, as part of a treasury of 55 massive, star-forming galaxies. The data on the properties of these galaxies will add insight to our picture of how galaxies grow and evolve over cosmic time. https://t.co/7vWkSbZCj4

Is it just me or is that galaxy getting closer? 👀 M90 (NGC 4569), shown here in this new Webb image, is indeed getting closer! Its orbit through the Virgo cluster has accelerated so much that M90 is in the process of escaping the cluster entirely and is moving in our direction. https://t.co/luJwJhgDwa

Have you ever wanted to have your name 'Roman' a million miles away? Now you can! Send your name along the Nancy Grace Roman Space Telescope, scheduled to launch Aug. 30, 2026! Sign up here: https://t.co/mSLkvPLgVB Submissions close July 12. https://t.co/jatFEfNAJO

Two eyes on the Black Eye Galaxy! Data from Hubble and @NASAWebb combine in this new image of the Black Eye Galaxy, also known as Messier 64. Astronomers used Hubble and Webb to study this galaxy to learn more about star formation in nearby galaxies: https://t.co/A4DJSMzIv1 https://t.co/3xZcw1GTRv

Now on display at Air and Space: 🌌 James Webb Space Telescope Pathfinder, a full-scale engineering model used by @nasawebb for critical testing in development of the spacecraft ☀️ Parker Solar Probe full-scale model built primarily out of spare parts and back-ups from the spacecraft that has flown through the Sun’s corona

Westerlund 2 is a young cluster of thousands of stars located about 20,000 light-years from Earth. This close-up image, roughly 12 light-years across, combines observations from NASA's Chandra X-ray Observatory & @NASAWebb.✨ https://t.co/9p96D0f1Zj

Webb has delivered the strongest evidence yet that its discovery of mysterious Little Red Dots (LRD) are “black hole stars.” They appear starting ~600 million years after the big bang, and scientists are still working out exactly what they are. https://t.co/MIEwfifyzi https://t.co/UEN7tLJzlF
Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.

- What is NASA Webb Telescope's engagement rate on X?
- NASA Webb Telescope (@NASAWebb) has an engagement rate of 0.059%, based on the median interactions across 5 original posts from the last 30 days against 3,517,754 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.059%, NASA Webb Telescope sits above the 25th percentile of the 36,378 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @NASAWebb have real engagement?
- There is not yet enough sample to rank this account against others of its size.
- When does @NASAWebb post?
- Most posts go out around 15:00 UTC, and Tuesday is its busiest day, at roughly 0.53 posts per day across the measured window.
