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.

Thanks @pinkastrophysicist.bsky.social for making me the delicious cake and taking this photo of me being equally excited and terrified 5 minutes after submitting my PhD 🥰🎂🧑‍🎓

Results from the first part of our fourth LIGO @egovirgo.bsky.social KAGRA observing run are out today!

We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars

📰 arxiv.org/abs/2508.18082

🔭🧪⚛️☄️ #GWTC4
New masses in the stellar graveyard plot, showing astronomical observations of black holes and neutron stars. The number of gravitational-wave observations of black holes is overwhelming. The plot is arranged to look nice, the horizontal axis has no meaning, but the vertical one shows masses. We have a significant range of masses from about 1 solar mass to over 200 solar masses for our largest merger remnant. New out today is a neutron star black hole binary GW230518_125908, as well as a lot of binary black holes.

JWST slays with this bisexual lighting for the super fascinating bullet cluster 😍🌈

Hold on to your butt because I am OBSESSED with this new JWST image 😍😍😍

This is the bullet cluster, and what you’re looking at is actually three different types of data that provide some of the strongest evidence for dark matter out there… (1/n) 🔭🧪

Oh wow, this is *such* a cool concept - a 'game' procedurally generated from Wikipedia, in which you can literally traverse all of human knowledge and walk down rabbit holes

I made this the other night while procrastinating, mainly because I thought all the posts about the blackout were boring. It feels like there is momentum bringing people together!
A poster for the economic blackout on February 28. It is a big red Jack rabbit on an aqua blue back ground. It says economic blackout in hand done black type. There are two black speech bubbles. One says “don’t buy stuff Friday February 28th. The other says we have power. Below it says No Amazon, Walmart, target, gas food, gas. Below that it says OK small business, use cash. Designed by Martha Rich.

Exciting news! We’re thrilled to announce that tapir Yuna gave birth to a rare and endangered Malayan tapir calf Sunday night. The newborn, covered in distinctive white spots and stripes resembling a fuzzy walking watermelon, is only the second tapir born in our 120-year history.

The most shocking part of this photo are the words that have not been painted over as yet.

They aren't even all "DEI" words. And yet, they are being wiped away.

A re-write of history's lessons, the removal of the things that build a functioning society, to please the Emperor.

Assuming we make it through the next couple of decades, this will be an incredible image for future historians/students of the Trump era

Here is a highly recommended thread that summarizes what has happened in scientific landscape in the US since Trump's inauguration. It makes for dystopian reading ⬇️

As expected, the Trump team is already deleting climate info from government websites. In anticipation, our team at Urban Ocean Lab created a permanent archive of 100+ key resources and published a permanent archive: www.urbanoceanlab.org/resource-hub 👩🏽‍💻
