Can’t have #BlackHoleWeek without the black hole in Planet Unknown! I love how it turns the player board on its head. Instead of placing tiles to cover a planet, you play them to avoid the black hole. Now, I wouldn’t want to live that close to a black hole, but it’s a fun addition to this game.

Next on the #BlackHoleWeek game list is Stellar. This 2-player game has players making telescope observations and recording insights in their notebooks. One of the objects you can observe are black holes, and I love how the illustrations seem inspired by real-world black hole observations.

For #BlackHoleWeek, I asked my spouse to play a bunch of games featuring black holes. First up? Twinkle, Twinkle, a tile-laying game of mapping the sky. Watch out, though. Black holes zap points from stars and planets. Satellites, though, don’t mind — it gives them a chance to take data!

When Black Holes Collide
A video illustrates two black holes merging, showcasing gravitational lensing effects on nearby stars. The event horizons and a combined Einstein ring are visible, with stars appearing inside and outside the ring. The merger emits strong gravitational waves, offering new cosmic insights. #BlackHoleWeek

@ArpBot Just in time for #BlackHoleWeek! Thanks ArpBot.

Celebrating #BlackHoleWeek, some of our scientists are working with the Science Ceilidh #SciComm team to create a binary black hole themed dance. Science Ceilidh work to connect researchers with their local communities through the arts. The final dance will be shared with participants at the upcoming #GR24Amaldi16 conference.

It's #BlackHoleWeek!
You might not expect it, but NSF–DOE Rubin Observatory's observations in visible light will help us learn about these dark and mysterious cosmic entities. But how?
Rubin won't observe black holes directly. Instead, it'll observe super-bright blasts of light called Active Galactic Nuclei, which are powered by hungry supermassive black holes.
AGN are some of the brightest objects in the Universe, which means we can see them extremely far away.

“I am most proud of is the LIGO-Virgo Binary-Black-Hole Orrery. I felt like I was part of a cool secret because these events were not public at the time, and I was an undergraduate working on a really exciting project” – Teresita Ramirez #HumansOfLIGO #BlackHoleWeek

Could you accidentally turn a game box into a black hole? I looked into that a couple years ago for #BlackHoleWeek!

It is Black Hole Week!
Let's take a trip around one. In this visualization from NASA, the camera approaches a black hole, skims the event horizon and slingshots back out.
A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds the black hole. Glowing photon rings form closer to the black hole from light that has orbited it one or more times.

We had to pull out Planet Unknown with the black hole board for #BlackHoleWeek. HAD to!

It's Black Hole Week.
Let's marvel at the images and size of these black holes taken by the Event Horizon Telescope over the past few years - Sgr A* the black hole at the center of our galaxy and the super massive black hole (SMBH) in galaxy M87. The images of SMBH TON 618 and the SMBH in the Andromeda galaxy are copies of the image of SMBH M87 but with scale info added by me.

GW230529 was a particularly interesting observation of a neutron star merging with an unusually small black hole. Mike Zevin, Vincent Juste, Shania Nichols, Shanika Galaudage discuss behind the scenes work on the discovery in #LIGOMagazine https://ligo.org/wp-content/uploads/2024/10/LIGO-magazine-issue25.pdf#page=6

Check out this wonderful biographical memoir of John Wheeler by his student Kip Thorne.
Physicist Wheeler, famed for his analogies and aphorisms, is also known for popularizing the term "black hole" and for inventing the terms "quantum foam", "neutron moderator", "wormhole" and "it from bit."

Black holes, black holes… nature’s cosmic vacuum cleaners, sucking in stars, secrets, and probably your missing socks. They bend space, time, and your will to resist googling “spaghettification.” What’s "inside"? No one knows. Maybe a party. BYO gravity. We celebrate the unknown this #BlackHoleWeek!

A couple years ago for #BlackHoleWeek, I looked at the black hole cards in Stellar and found some results they reminded me of.

“[My] favourite event is the [neutron star–black hole] NSBH merger GW200105; I picture NSBHs events as the 'experienced' black hole showing the 'baby' neutron star what to do, and always find it funny.” – Leigh Smith #HumansOfLIGO

“I love to take my 7-year-old brother Tommy to the Adler planetarium and talk to him about space. He thinks that black holes are really cool, and whenever I feel stressed about research, I like to remind myself of this perspective by looking at one of his gravitational-wave inspired drawings that I keep at my desk” – Maya Fishbach #HumansOfLIGO

To kick off #BlackHoleWeek, here's a little video I did last year counting down my three fave black holes! youtu.be/BWDc8b_dkrM?...

🚨 Neues Headerbild 🖼️
Forschende der unabhängigen @maxplanckgesellschaft Forschungsgruppe „Beobachtung und Simulation von kollidierenden Binärsystemen“ haben untersucht, wie die Spins verschmelzender Schwarzer Löcher den „Kick“ / Rückstoß nach ihrer Verschmelzung beeinflussen und wie dies wiederum die Spins der Verschmelzungsüberreste nach wiederholten Verschmelzungen in dichten Sternumgebungen beeinflusst.
Das Titelbild zeigt einige ihrer Ergebnisse.

🚨 New header picture 🖼️
Researchers from the independent @maxplanckgesellschaft research group “Binary Merger Observations and Numerical Relativity” have studied how the spins of merging black holes influence the recoil after their merger, and how this in turn influences the remnant spin magnitudes after repeated mergers in dense stellar environments.
The header picture shows some of their results.

In case you missed it during the most recent #blackHoleWeek, NASA put out a very nice visualization of flying around and of falling into a black hole, based on computations by @SchnittGetsReal. It can even be viewed as a 360 video if you have a #VR headset. They also have explainer versions for both on the same channel.
