Happy birthday to #astronomer Vera Rubin (neé Cooper, ‘28-‘16) & her discovery that angular motion of galaxies deviates from predictions, 1st evidence for dark matter, now known as 5x as common as matter & the stuff which dictates dynamics of galaxies & evolution of our universe! The Nobel committee waited 3 years after she died to reward another for the theory of dark matter.

She found 6 months mat leave post MSc very 🧵

My linocut portrait of astronomer Vera Rubin with short hair, glasses and resting her face in her hand in burgundy on a background of outer space with stars and galaxies in black with blue and pink splotches to mimic how dust bends light in space. At the base of the print is a large spiral galaxy with a plot of orbital velocity versus distance going out from its centre (so the distance axis is indeed distance from centre). There are two lines labelled “observed” which goes up from the origin and then is a pretty flat wavy line all the way across. This line marks the bottom of Rubin. Below it is a wide empty gap of visible white paper down to the second line labelled “predicted”. The Predicted line goes up from the origin to a peak where it diverges from the observed and falls smoothly back down in a gentle curve.

Astronomer has now suspended CEO Andy Byron over the Coldplay concert incident.
Big oops! 😬

"A video of Astronomer’s married CEO and its chief people officer on a stadium kiss cam went viral. Should the company’s board remove them?"

The Coldplay Concert Couple Can’t Be Trusted to Lead

"In a viral video, Astronomer CEO Andy Byron and chief people officer Kristin Cabot appear as a happy couple enjoying the concert at Gillette Stadium, outside Boston—until they realize their inappropriate embrace is being broadcast to the world."

Happy Space Science Saturday! Did you know that today Saturn begins its retrograde motion? Normally, Saturn moves eastward against the background of stars, but during retrograde it appears to pivot and move westward through the constellations. This apparent backward motion isn’t because Saturn actually reverses its orbit, but rather because of Earth’s own motion around the Sun. As Earth passes Saturn in its orbit, our changing perspective makes Saturn appear to move backward in the night sky.

Happy birthday to #astronomer Henrietta Swan Leavitt (1868-1921) who set the scale of our Universe. My portrait of Leavitt is printed in silvery lavender ink on Japanese kozo (or mulberry paper). Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco, 🧵

Dr. Alexandre Santerne 🌍

Hello #FediScience, migrating from astrodon.social (about to close), I am joining you here (inspired by @wolfgangcramer), so it's time for a new #Introduction

I'm Alexandre Santerne (call me Alex), #astronomer working @LAM_Marseille & teaching at Aix-Marseille #University (France).

I'm expert in finding #NoPlanetB 😀 (#planets around other #stars).

I want to work in a #fair, #inclusive, and #sustainable #research #environment, so I (try to) act accordingly. I'm a member of @labos1point5

I toot a lot about #Astronomy, #Astrophysics, #Space but also a lot about #ClimateChange and #Climate.

Since 2019, I completely boycott planes, and I travel by #train (long distance) and #bike (short distance) as much as I can.

My other interests include #photography (visit my Flickr gallery in my profile) #Astronomy #Space

Oh, in case you don't know where Aix-Marseille is (trick: in 🇫🇷 ), the image below (credit: #NASA / JPL-Caltech / Space Science Institute) is indicating where I am, as seen from #Saturn...

... and where you also are, together with 8B people as part of 2M species 😀

This rare image taken on July 19, 2013, by NASA's Cassini spacecraft has shows Saturn's rings and our planet Earth and its moon in the same frame. At the time, Cassini was 2013 from a distance of about 898.414 million miles (1.445858 billion kilometers) from Earth. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself) taken by Cassini's wide-angle camera.

Happy birthday to Caroline Herschel (1750 – 1848) a trail blazing woman in #astronomy. Hers was a real life Cinderella story, where rather than marrying a prince, she made a life and career for herself. Marriage her expected role but she was deemed unmarriageable, since a childhood bout of typhus stunted her growth. Her mother thought she should train to be a servant, & purposely stood in the way of her learning French, or music,🧵

Happy Space Science Sunday! Did you know that Voyager 1 is the first man-made object to travel past the heliosphere, a protective area of magnetic energy and particles generated by the Sun. It crossed this boundary into interstellar space in 2012. Miraculously, the spacecraft, which launched in 1977, is still sending data back to Earth. While there have been some technical difficulties, like communication issues and power limitations due to the decay of its radioactive power source, the team behind Voyager 1 remains committed to maintaining the project and gathering data for as long as possible.

Space Catitude 🚀

For a periods in the late 80s, early 90s, late 90s, and early 2000s, I was a professional #Astronomer (yet another workstation jockey) with a particular interest in #BioAstronomy -- planets, star forming, potential habitats -- that sort of thing.

Used data-reduction software. And I wrote some in #FORTRAN

Along the way, also learned BASIC, C, C++, Pascal, and then #Python

Helped develop the #NICMOS camera for Hubble. Then got to reduce some data from it to study protostars.
