Artemis 1 moon rocket might still fly this week, NASA says https://t.co/8OgQcBdhGs https://t.co/UpupGs0FKn

Artemis I launch was scrubbed today after an engine bleed issue prevented chilling to the correct temp range. However, it was an honor to support w/@NASA_Astronauts and thank the people who have devoted many years to building this incredible vehicle. Thank you and Go Artemis! https://t.co/uibqN5Js0k

Multi-observatory views of M74, scientists combine data from telescopes operating across the electromagnetic spectrum to truly understand astronomical objects. In this way, data from Hubble and Webb compliment each other to provide a comprehensive view of the spectacular M74 galaxy.

Making dreams happen! ✨ Awardees of @NASA’s first-of-its-kind Minority Serving Institutions (MSI) Space Accelerator got some in-person coaching at a place where their visions could one day become reality: the Jet Propulsion Laboratory. ➡️ https://t.co/euYAPEjGNt https://t.co/4pQdEdsoCK

#TDIH in 1970: The McDonnell Douglas DC-10 flew for the first time. The DC-10 resolved the need for an airplane that was smaller than the huge 747 but could seat 250 to 360 passengers. 📸: DC-10 Series 10 https://t.co/bxRfN4Idij

The @Space_Station isn’t just a place for astronauts to conduct science. It also serves as a spark of inspiration to all. From tracking the station flying overhead to connecting students via ham radio, there’s a way for everyone to come along on the journey aboard station. https://t.co/tk4Y0SE3Sw

Brightest Possible Star (Measured from the surface of said star)

So, I am wondering what the highest possible luminosity of a star feasibly is, before the necesary energy would cause it to rip itself apart. I tried to find it, but all I found where *lists* of the brightest stars, and even then I couldn't narrow it to the brightest at its surface (what I'm asking) or the brightest in the earths sky. So, what is the highest possible luminosity of a main-sequence star?

#OTD in 1962, a U-2 confirmed the presence of Soviet intermediate-range ballistic missiles in Cuba, which led to the Cuban Missile Crisis. Pictured here is the SA-2 surface-to-air missile (SAM) site under construction at La Coloma. https://t.co/Nk6BauMFXw

NASA fueled the Space Launch System moon rocket for liftoff Monday on the long-overdue Artemis 1 test flight, but stormy weather, brief signs of a hydrogen leak, trouble cooling a main engine, and then a valve glitch forced teams to delay the mission. https://t.co/MwexZU03oN https://t.co/y9XPUQsPh4
