Meet Heather Williams, SAO's first Chief Operating Officer! cfa.harvard.edu/news/heather-w…
Want to know what's in the air we breathe? With the @NASA and @CenterForAstro TEMPO mission, we're hoping to get answers! Join us Monday, 4/24, at 12:00 pm ET for a Reddit AMA and learn more about how TEMPO will transform our understanding of air quality. reddit.com/r/askscience/

1/2: Congrats to @ShepDoeleman for being awarded the Georges Lemaître International Prize! The award is named after the father of the Big Bang theory, and was presented to Shep because of his pivotal role in capturing the first image of a supermassive black hole in 2019.
In one week! @BadAstronomer and @aussiastronomer present UNDER ALIEN SKIES: A SIGHTSEER'S GUIDE TO THE UNIVERSE Details and registration: science.fas.harvard.edu/event/harvard-…
Four years ago today from our @CenterForAstro, you got this first look at a black hole.
This is the first image ever of a black hole. The breakthrough discovery by the @ehtelescope is an image of Messier 87’s (M87’s) supermassive black hole in the center of the Virgo galaxy cluster, 55 million light-years away. #EHTBlackhole #RealBlackHole
Right now, a washing machine-sized scientific instrument hovers above us. Launched today on the Intelsat 40e satellite, @TEMPO_Mission, a @CenterForAstro and @nasa_langley collaboration, is the first space-based instrument to track air pollutants hourly across North America.
I remember crowding around my school's TV to witness new achievements in space exploration. I hope this launch offers the same national experience of hope and awe as we drastically advance the conversation on how air pollution affects nature and communities across North America.
LIFTOFF FOR TEMPO! Congratulations to the @TEMPO_Mission team for a successful launch this Friday morning. 🚀 #TEMPO
Spacecraft separation confirmed! The Intelsat satellite hosting our @NASAEarth & @CenterForAstro #TEMPO mission is flying free from its @SpaceX Falcon 9 rocket and on its way to geostationary orbit.
LIFTOFF FOR TEMPO! Congratulations to the @TEMPO_Mission team for a successful launch this Friday morning. 🚀 #TEMPO
The Sun has set here in Cape Canaveral, Florida. Less than 5 hours until @Intelsat 40E blasts off from Launch Complex 40, carrying our @TEMPO_Mission payload with it! Who’s watching with us at midnight? —> NASA.gov/live #TEMPO
The stage is set for the launch carrying #TEMPO, which will help us study what's in the air we breathe. @TEMPO_Mission, a collaboration with our @CenterForAstro, will be the first space-based instrument that can measure North American air quality hourly.
In 1848, to understand the weather, the Smithsonian distributed monitoring equipment to volunteers across the U.S. This system gave rise to what we now know as the National Weather Service. This week, we begin tackling a new challenge—monitoring pollution across the continent.
Our @TEMPO_Mission instrument is packed up and READY FOR LAUNCH. T-minus 8 hours (or so) until liftoff! #TEMPO

The TEMPO mission is nothing short of amazing. The size of a washing machine, it will be the first space-based instrument that can measure North American air quality hourly down to the ZIP code level. Image credit: Ball Aerospace
Apps on our phones tell us exactly when it will rain. Soon, we'll measure and predict the movement of air pollutants with the same precision with @CenterForAstro and @NASA_Langley's @TEMPO_Mission, hitched to satellite Intelsat 40e. Image credit: Maxar
The @TEMPO_Mission crew, which includes members of @NASA_Langley and @CenterforAstro, has begun to gather in Cape Canaveral, Florida! Let the countdown clocks begin! ⌛🚀
