New results: EHT scientists have imaged the distant blazar J1924-2914, revealing previously unseen details of the source structure. A blazar is a supermassive black hole ejecting a powerful jet along our line of sight that can outshine its entire galaxy! 📡🌎📡

1900 kcal released in 2h 20min is 10^10 erg/s. Eddington luminosity for ~95 kg guy is 6*10^9 erg/s
I was super-Eddington (~1.7 L_Edd) for 2 hours today, back to quiescence ~0.2 L_Edd, expecting next quasi periodic outburst in ~2 days. To become super-luminous, go for a run!

I guess it's time to start looking for a job in a country that is not sponsoring Russian terrorism.

Interesting take from an old man in a weird hat. Although I wonder whether Russian murderers and rapists aren't perhaps just a little bit more guilty than their victims?

Army of looters!

.Hanna Hopko: 'Does humanity end at the NATO border?' #ProtectUАSky

📣 As bombs fall on Ukraine, Europe sends €700 million EVERY DAY to Russian oil, coal & gas companies, fueling Putin's war machine.
Ahead of the EU Council Summit, activists from Ukraine call all politicians to cut Europe off from Russian fossil fuels. Which side are you on? 🔥

NATO could and should stop Putin with a direct intervention. We're looking at a murder being committed but we choose not to stop the murderer, even though we are much stronger than he is. It's inhumane, and it's a disgrace for the west.

Free Belarus! Jail for Lukashenko!

Eternal shame on you, Germany, Italy and Hungary, fucking axis reborn!

It’s not about the money

A cool little paper just got published: Photon rings of spherically symmetric black holes and robust tests of non-Kerr metrics journals.aps.org/prd/abstract/1… (also arxiv.org/abs/2109.10840)

The EHT Collaboration is proud to announce EHT Early Career and Outstanding PhD Awards. We highlight awardees by area of expertise, concluding with Official Papers and Theory: Lia Medeiros (IAS), Maciek Wielgus (MPIfR) and George Wong (PhD Illinois)

We're back and we've added polarization sprinkles to our M87 black hole donut! They are nicely ordered in a spiral structure, and help us map out the magnetic fields near the event horizon for the very first time!

Yet another pro-Trump rapper😹

A great success for private corporation SpaceX, anti-science clown Elon Musk, & climate-change-denying NASA Administrator Jim Bridenstine, using the space program as a tool for nationalism & profit.
