Star S301 orbits Milky Way’s black hole at 25,000 km/s, fastest ever recorded

Questions about this coverage

How did the left and right cover Star S301 orbits Milky Way’s black hole at 25,000 km/s, fastest ever…?

Of the 79 outlets on this story carrying a published leaning rating, 34% are rated left, 51% are rated centre, 15% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 127. The sections above set out what each side emphasised, in its own terms.

Is Star S301 orbits Milky Way’s black hole at 25,000 km/s, fastest ever… left or right?

Neither side dominates it. Of the 79 rated outlets on this story, 34% are rated left, 51% are rated centre, 15% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.

Is the coverage of Star S301 orbits Milky Way’s black hole at 25,000 km/s, fastest ever… biased?

Star S301 orbits Milky Way’s black hole at 25,000 km/s, fastest ever recorded is one event reported by 127 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.

Which outlets covered Star S301 orbits Milky Way’s black hole at 25,000 km/s, fastest ever…?

127 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.

How fast is the star S301 moving?

The star S301 orbits the Milky Way’s central black hole at 25,000 kilometres per second, or about 8% the speed of light. This is the fastest speed recorded for any star in the galaxy, as reported by the Associated Press and Live Science.

Why is this star important for scientists?

S301’s tight orbit around the black hole could allow scientists to measure the black hole’s spin for the first time. This would test Einstein’s general theory of relativity and provide new insights into the properties of supermassive black holes, according to digests from Live Science and Science News.

Which outlets reported the discovery?

The discovery was reported by five left-rated outlets, including the Associated Press and Spiegel, and seven centre-rated outlets, such as Live Science and Science News. No right-rated outlet carried the story, as noted in the coverage comparison.
