Worldwide network of 8 radio telescopes made 1st picture of a black hole, showing the object, centered in M87 galaxy 55 million light-years from Earth, has 6.5 billion x the Sun’s mass, is about 38 billion km (24 billion miles) across & spins clockwise. #GAM2024 #RandomAstroFact

We're highlighting 125 years of AAS key activities, awards and prizes, scientific events, and discoveries!

The Orion Nebula is visible by eye although about 1,300 light-years away. In 2019, a telescope measuring submillimeter waves caught a stellar flare 10 billion times stronger than one from the Sun blasting from a new star in the nebula. #GAM2024 #RandomAstroFact

Nominate a colleague (or yourself) for the Newton Lacy Pierce Prize. Criterion: outstanding achievement, over the past 5 years, in observational astronomical research based on measurements of radiation from an astronomical object. Nominations due by 30 June.

Three kinds of rain to stretch the brain: On Saturn’s moon Titan, methane droplets (very cold) fall; on Venus, sulfuric acid rain drizzles & on the Sun coronal rain (extremely hot) occurs as hot plasma in the outer atmosphere cools, condenses & drops. #GAM2024 #RandomAstroFact

#Prize 🏆 Congratulations to Thomas Dauser, research scientist in X-ray astronomy at FAU Erlangen-Nbg Faculty of Sciences & member of the X-IFU Consortium, who receives the 2024 HEAD Innovation Prize from the American Astronomical Society (AAS) 🔗 x-ifu.irap.omp.eu/consortium/tho…

Hypergiant VY Canis Majoris is one of largest, most massive & brightest stars in our galaxy. Matter flowing from it makes a clumpy nebula. VY is 300,000x brighter than Sun & much bigger than supergiant Betelgeuse. It may explode or become a black hole. #GAM2024 #RandomAstroFact

NEW VIDEO! Elizabeth Jensen (Planetary Science Institute (PSI)) chats about her article on magnetic fields: youtube.com/watch?v=ZMJ-UD…

The goal of the AAS Journals Author Series is to connect authors w/their article, their human story & the larger #astronomy community. #TheGoodStuff #ExploreAstronomy

The Rho Ophiuchi cloud complex is the closest star-forming region to Earth. In stellar nurseries like this one, jets from young stars impact surrounding molecular gas, lighting it up. #GAM2024 #RandomAstroFact

The Milky Way has 1.5 trillion times the mass of the Sun. Note that the Sun has 333,000 times the Earth’s mass & the Earth's mass is 5.97 x 10^24 kg (1.32 x 10^25 pounds), give or take. #GAM2024 #RandomAstroFact

Most pictures of the Apollo 11 astronauts on the Moon show Buzz Aldrin. That’s because Neil Armstrong mostly held on to the camera. Armstrong’s & Aldrin’s footprints can still be seen undisturbed at Tranquility Base where their lunar module Eagle landed. #GAM2024 #RandomAstroFact

Sharpest Sun images show bright, Texas-sized cells separated by darker lanes. Hot plasma ascends from below in cells, cools & flows back down through lanes. Five million tons of hydrogen gets converted into solar energy each second in the Sun's core. #GAM2024 #RandomAstroFact

It was great to meet with American Astronomical Society (AAS) to talk about all the ways Science Committee Democrats and I can support deep space exploration and women in STEM. Meeting with these amazing scientists was a great reminder, you can wear pink and lead in science (or in office)!
