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.

In collaboration with Soton Astrodome I used some of their old acetate star maps (from @esoastronomy I think) to make double exposure cyanotypes about space & memory.
I used 30 star maps to make a star.
Would LOVE to carry on this theme but I used all the sheets I have.
Any #astronomer out there (hello @astroroyalscot.bsky.social )know of acetate star maps that could be donated?
I can donate some of the art in return.
Collaboration ideas welcome! -

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 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, Ursa Minor & Andromeda). 🧵1/

#OnThisDay Birth Anniversary of William Thomson, 1st Baron Kelvin (1824).
The Human #Genome Project announced the completion of a "rough draft" sequence (2000).
Birth Anniversary of #French #Astronomer Charles Messier (1730) - most notable for publishing an astronomical catalogue consisting of 110 nebulae and star clusters.
Today is International Day Against Drug Abuse and Illicit Trafficking.

Today is the solstice. The longest day in the northern hemisphere, but which is the shortest night? Last night or tonight?
Thank you. 🌞🌓 -

#NASA Completes #NancyGraceRoman #Space #Telescope, Ahead Of Schedule And Under-Budget, named after NASA's first chief #astronomer, is headed to space in September aboard a SpaceX Falcon Heavy, months ahead of its originally planned May 2027 launch.
Roman's primary mirror is 7.9ft same size as #Hubble's but 1/4 weight, sending visible and infrared light to two sensors. First is Wide Field Instrument, 300-megapixel camera. Second is #RomanCoronagraph, a polarized sensor.

Clouds of #water #ice thread stellar nurseries in #MilkyWay
Findings support idea water pervades galaxy’s planet-building material
Reaching hundreds of light-years, icy clouds drape two of galaxy’s active #star-forming regions, #astronomer Gary Melnick and team report. Findings paint broadest picture of #interstellar ice’s distribution, and confirm predictions water, key ingredient for life on Earth, occurs across huge areas of interstellar #space.

Meton - Virtual Mechanical Moon and #Eclipse #Calculator
This awesome tool was created by prof. em. Thomas Weibel from Basel, Switzerland. Here is the beginning of the description from the website:
"The metonic cycle is a period of 19 years corresponding to almost exactly 235 synodic lunar months or full cycles of #moon phases, named after meton of athens, a greek #mathematician and #astronomer from the 5th century bc."
I love it :-)

Time for a midweek break from #astrophotography from our #constellation of the #month #Camelopardalis to show you Petrus Plancius!
Who is Petrus Plancius? Another of the multi-hyphenate astronomers of the 1600s, who we met in this week's episode!

A small object past #Pluto may have a thin #atmosphere
The possible atmosphere around #2002XV93 “suggests that small icy worlds beyond Neptune may not be as inactive or unchanging as we often assumed,” says observational #astronomer Ko Arimatsu of the National Astronomical Observatory of Japan in Mitaka. “Until now, Pluto was the only trans-Neptunian object with a confirmed atmosphere.” He and his colleagues report the observations.

New episode comes out tomorrow!
We'll be meeting a new (to us) historical figure in #american #astronomy & exploring the science of sunspots.
Anyone have a guess on which #astronomer we paired with this topic??
