Hubble engagement report
@NASAHubble - 8.9M followers on X
Measured over 15 original posts from a 30-day window, last computed on August 31, 2026.
Engagement
A typical post picks up 1.8K interactions against 8.9M followers, an engagement rate of 0.021%. Measured over 15 original posts, its engagement rate beats 58% of 3,739 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 110K times each, and 1.66% of those impressions turn into an interaction. That is about 1.23% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.1 post a day over the last 30 days, with activity on roughly 63% of days. Most posts go out around 15:00 UTC, and Tuesday is the busiest day of the week. Of the 15 posts sampled, 100% carry an image or video, 7% are part of a thread and 87% link out. The account's strongest tracked post pulled 25K interactions, about 14x its own typical post. Recurring topics include #mondaymotivation, #otd.

Compared with accounts its own size
Hubble's engagement rate beats 58% of the tracked X accounts closest to it in follower count (3,739 accounts, accounts of similar size (decile 10 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 71% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.021%, Hubble sits above the 25th percentile of the 36,261 accounts in this comparison. That places it in the below the median band, which runs 0.012% to 0.08%.

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.

The final space shuttle mission touched down 15 years ago today, marking the end of NASA's 30-year Space Shuttle program. As the world's first reusable spacecraft, the shuttles accomplished so much over 135 missions. From building and supporting the @Space_Station, to launching and servicing missions a variety of commercial and scientific satellites such as @NASAHubble, to conducting groundbreaking research, it left an enduring legacy as a platform for exploration, science, and international cooperation.

In these cosmic captures, the Lion Nebula is the mane attraction π¦ A dying star casts off its outer layers to create this intricate structure of gas and dust. Scientists think that it will disperse in about 10,000 years... which is very short, in astronomical terms. β¬οΈ https://t.co/Ik4JXOtijd

The Chandelier Cluster β¨π Every "lightbulb" in this cosmic chandelier is actually an individual star, located about 27,000 light-years away. This is a globular star cluster, which means it's a tightly packed group of stars held together by gravity: https://t.co/GTbyXKTwi5 https://t.co/0HMeB1p8NV

Some serious star power π€© The star cluster NGC 6791 is one of the oldest and largest open clusters known to exist. At about 10 times larger than most open clusters, it's home to roughly 10,000 stars. NGC 6791 resides about 13,300 light-years away: https://t.co/q6gPwaEQSB https://t.co/68uf9CvZvM

Hold my hand? In this Hubble view, two galaxies known collectively as NGC 5331 are seen just beginning to "link" their spiral arms. This galactic interaction is unfolding about 450 million light-years away, in the constellation Virgo. Read more: https://t.co/V0qJECHPZ7 https://t.co/Z47EjurutF

Spot the supernova! π₯ In the top right corner, it's so bright that it could be mistaken for a foreground star located in our galaxy, but its home is in the outskirts of a galaxy located 11 million light-years from Earth: https://t.co/SYye2JViCS https://t.co/1cloWzKJd4

A galactic photobomb! By a chance alignment, two galaxies overlap in this Hubble image. And another galaxy appears, too β most of the stars sprawled across the background belong to another spiral galaxy called NGC 253, which is out of frame to the right: https://t.co/TyCFOo6a0v https://t.co/O4FI7o8EaK
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.

Reading these numbers
A typical post picks up 1.8K interactions against 8.9M followers, an engagement rate of 0.021%. Measured over 15 original posts, its engagement rate beats 58% of 3,739 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 110K times each, and 1.66% of those impressions turn into an interaction.

- What is Hubble's engagement rate on X?
- Hubble (@NASAHubble) has an engagement rate of 0.021%, based on the median interactions across 15 original posts from the last 30 days against 8,903,454 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.021%, Hubble sits above the 25th percentile of the 36,261 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 @NASAHubble have real engagement?
- Its engagement rate beats 58% of the tracked X accounts closest to it in follower count (3,739 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @NASAHubble post?
- Most posts go out around 15:00 UTC, and Tuesday is its busiest day, at roughly 1.07 posts per day across the measured window.
