Absolutely mind-boggling to me that this isn't a fully solved problem. "GW250114"? With "25" being the year number? Do you think gravitional wave observations aren't going to continue beyond this century?

The strongest gravitational wave signal yet. GW250114 was detected by both arms of the Laser Interferometer Gravitational-wave Observatory (LIGO) in Washington and Louisiana USA earlier this year.

This artwork imagines the ultimate front-row seat for GW250114, a powerful collision between two black holes observed in gravitational waves by the US National Science Foundation LIGO. It depicts the view from one of the black holes as it spirals toward its cosmic partner.

#GW250114's source is much like that for our first detection GW150914. Progress with our detectors means that the signal is much louder. Therefore, we can make much better measurements

Measured masses for GW150914 and GW250114. Both have black holes of around the same masses (roughly 35 times the mass of our Sun). However, the uncertainty on the measurements for GW250114 are much smaller. This is the type of thing that makes astrophysicists excited.

Mirror, mirror, reflecting our [LASER] beam...
What is the loudest [gravitational wave] signal that we've seen?

It’s #GW250114!

(Yes, it’s been two weeks since it was announced, but I can still celebrate! 🎉 )

An infographic created by @astronerdika titled “MIRROR, MIRROR, reflecting our LASER beam… what’s the LOUDEST signal gravitational wave we’ve seen?” explaining the gravitational-wave discovery GW250114 and how the observation confirms Hawking’s area law. The visual shows the mirrors in a gravitational-wave interferometer speaking about the loudest event they have seen. There are several illustrations as follows: 1. A simplified diagram of a laser interferometer. A red laser beam from a labeled “LASER source” hits a beam splitter, travels down two perpendicular arms, reflects off round mirrors, and recombines at a labeled “detector.” A label near the top-right mirror reads: “the DETECTOR, signal seen by LIGO Hanford & LIGO Livingston.”
 2. An illustration of a binary black hole merger, with two black circles spiraling inward. They are labeled ~34 solar masses and ~32 solar masses. Surrounding spiral lines represent gravitational waves. A nearby caption reads: “the SOURCE, Discovered in 2025, on January 14, at 08:22:03 UTC.” 3. A prominent speech bubble with white text on a purple background states: “GW250114 is the loudest & clearest signal we’ve seen!” A smaller note below reads: “as of January 2025.” 4. Another speech bubble reads: “AND we saw that Hawking was right too!” 5. Visual explanation of Hawking’s Area Law. Two small circles labeled “this BH” + “this BH” are shown to the left of a “<” symbol, pointing to a larger circle labeled “the surface area of the merged BH.” Below there is the explanatory sentence: “GW250114’s remnant event horizon area is larger than the sum of the individual areas.” 6. A section titled “the PAPERS” lists two arXiv references: https://arxiv.org/abs/2509.08054 and https://www.arxiv.org/abs/2509.08099 Note: This infographic plays off the classic line from Snow White, “Mirror, mirror on the wall…” Here, the “mirrors” are the ones inside the laser interferometer, reflecting light to detect passing gravitational waves.

GW250114 reveals signatures of post-merger black-hole horizon - Nature
The observation of a direct wave after the merger of two black holes reveals signatures associated with the remnant black-hole horizon, establishing an observational channel to directly measure frame-dragging effects in black-hole ergospheres and probe the horizon surface gravity.

On 14 January 2025, the LIGO's detectors captured GW250114, a gravitational wave signal (GWS) caused by two black holes' coalescence, each about 30 times the size of our Sun.

With a signal-to-noise ratio of 80, as opposed to 26 for GW150914...

When a black hole is formed in a merger it emits a set of #GravitationalWave frequencies, ringing like a bell

Measuring these tests the nature of black holes. #GW250114 lets us measure multiple overtones, and they agree with theory

Loud signals are perfect for testing Einstein's theory of general relativity.

The previous loudest signal was #GW230814 with a signal-to-noise ratio of 42. #GW250114 has a signal-to-noise ratio of 80. This enables some extremely precise tests!

Our detailed study of #GW230814 is out

arxiv.org/abs/2509.07348

We can precisely test general relativity with this loud signal. Most tests show agreement with Einstein's theory, but some…

The deviations can be explained by detector noise. Having multiple detectors is important!

A comparison of GW250114 with our first detection GW150914. The stretching of space in the new black hole merger (top) is similar to that in the first one ever spotted (bottom), but because of reductions in the noise in the detectors, the signal stands out far more clearly.

Astronomers have, for the first time, probed the event horizon region of a black hole using gravitational waves. Analyzing the loudest detected signal so far — GW250114 from a binary black hole merger — researchers from OzGrav/ANU identified a previously under-explored "direct wave" component

Timeline of LIGO Virgo KAGRA observing runs, showing the increase in detector range and increase in the number of detections Comparison of our first detection GW150914 and recent loud detection GW250114. While the sources are similar, GW250114 is much louder because of advances in our detectors. This means that measurements of source properties are much more precise.
