As I toil away at my current work in progress, wondering if I’ll ever finish or if anyone will read it, it’s energizing to hear praise for my first book! There’s some interesting #astrohistory coming in the Frost book too.

Loved the first edition! Taught me a lot of useful Astro history.

🧵 12 April 1633: the inquisition of Galileo was begun with the first interrogation by chief inquisitor Vincenzo Maculani da Firenzuola, appointed by Pope Urban VIII. On 22 June 1633, the Roman Inquisition concluded the trial of Galileo with a condemnation for heresy. 🔭 🧪 ⚛️ #histsci #astrohistory
The image, featuring Galileo facing the Roman Inquisition (1857), is a painting from Cristiano Banti (1824–1904).
Description: Vincenzo Maculani (in priestly vestments) reading the charges against Galileo Galilei (standing).

1/2 I got chills! This is #astrohistory. This black & white picture of Jupiter, taken at 1:14 a.m. on 11 March 1991 by the Planetary Camera on NASA's HST is the first of many Hubble observations recording the detailed evolution of Jovian weather. ➡️ hubblesite.org/contents/new... 🔭 🧪 #planetsci
The image features a black and white picture of Jupiter, taken on 11 March 1991 by the Planetary Camera on NASA's Hubble. It is HST's first observation of Jupiter.
At the lower right, the Great Red Spot is visible. Also on the right, near the equator, you can get a glimpse of the satellite Europa while it is disappearing behind the limb of Jupiter.

In J.Herschel's publication above, 🜨 are globular clusters, and Δ are objects from Dunlop's Catalogue. About Dunlop's observations, Herschel remarked that he couldn't find many of his objects, blaming lack of light in Dunlop's instrument for him "setting down nebulæ where none exist" #astrohistory
Excerpt from an earlier part of the John Herschel publication from the previous post:

"(7) Of the objects remaining, 135 are nebulæ and clusters of my Father's catalogues, now, for the first time, reobserved; 9 are Messier's, 5 of which are identical with objects catalogued by Mr. Dunlop; and 206 others have also been identified, with more or less certainty [...], with objects observed by Mr. Dunlop, and described in his Catalogue of Nebulæ. The rest of the 629 objects, comprised in that catalogue, have escaped my observation; and as I am not conscious of any such negligence in the act of sweeping as could give rise to so large a defalcation, but, on the contrary, by entering them on my working lists (at least, until the general inutility of doing so, and loss of valuable time in fruitless search, thereby caused it to become apparent), took the usual precautions to ensure their rediscovery; and as I am, moreover, of opinion that my examination of the southern circumpolar region will be found, on the whole, to have been an effective one, I cannot help concluding that, at least in the majority of those cases, a want of sufficient light or defining power in the instrument* used by Mr. Dunlop, has been the cause of his setting down objects as nebulæ where none really exist. That this is the case, in many instances, I have convinced myself by careful and persevering search over and around the places indicated in his catalogue."

The museum has some really interesting artifacts in it too, like the prism that William Herschel used to discover infrared light: 🔭 #astrohistory

To anyone ever in Bath in the UK, I highly recommend visiting the Herschel museum! It's pretty incredible that the first planet ever discovered with a telescope was found at a pretty unassuming townhouse in a Georgian-era vacation town... 🔭 #astrohistory

@bathastronomers.org.uk accompanied the @herschelmuseum.bsky.social on Thu 13th Mar to celebrate 244th anniversary of the discovery of Uranus from the garden at 19 New King Street. A sold out night with visitors looking up from that same place to giggle as everyone pronounced Uranus carefully.

In 1610 (some sources mention the 12th March, others the 13th) Galileo Galilei published the 'Sidereus Nuncius' (Sidereal Messenger or Starry Messenger) in Venice at the printer Tommaso Baglioni. Image source and more➡️ en.wikipedia.org/wiki/Sidereu... 🔭 🧪 #astrohistory #histsci 🧵

13 March 1781: Uranus was discovered by William Herschel. At first he thought he had found a comet. Later, he and others realized it was a new planet in orbit around our Sun. Uranus was the first new planet discovered since ancient times. ➡️ science.nasa.gov/uranus/ 🔭 🧪 #planetsci #astrohistory 🧵
This image of Uranus from Webb's NIRCam captures its seasonal north polar cap and dim inner and outer rings. The pic also shows 9 of the planet’s moons; clockwise starting at 2 o’clock, they are: Rosalind, Puck, Belinda, Desdemona, Cressida, Bianca, Portia, Juliet, and Perdita.

So wonderful achievement! Using the LSST Camera, Rubin Observatory will repeatedly scan the southern night sky for a decade, generating a huge amount of data to study phenomena such as dark matter, dark energy, the Milky Way, and Solar System objects. 🔭 🧪 #cosmology #astrosci #astrohistory

Lights, camera, action! The world's largest digital camera has been installed at NSF–DOE Rubin Observatory! 🤩 The LSST Camera was the final major component of the observatory. With it in place, Rubin officially enters its final phase of testing!🔭 🔗: rubinobservatory.org/news/lsst-camera-installed

Did you know? The first image of a star was a daguerreotype of Vega, taken in 1850 by J.A. Whipple. pweb.cfa.harvard.edu/about/about-... #historyofastronomy #astroedu

#Hubble observed impacts on Jupiter produced by minor bodies in the Solar System. This stunning mosaic of Hubble's WFPC-2 images shows the collision of Comet Shoemaker-Levy 9 chunks with Jupiter, which happened in July 1994. ➡️ hubblesite.org/contents/med... 🔭 🧪 #planetsci #astrohistory #HST🧵
This mosaic of Hubble's WFPC-2 images shows the evolution of the impact site on Jupiter  by the 21 chunks of comet Shoemaker-Levy 9, in July 1994. The four images, beginning at lower right, chronicle the results of the collision.
Hubble began snapping pictures of the impact area just five minutes after the collision. Less than two hours later, a plume of dark debris is visible (bull's-eye pattern, image second from bottom). Two impact sites are visible in the next picture, taken a few days later. The final snapshot shows three impact sites, the newest near the bull's-eye-shaped region.

Étienne Léopold Trouvelot made more than seven thousand astronomical drawings, covering everything from the planets to the coming of a solar eclipse. He drew this one, of Jupiter, in 1882. #art #historyofastronomy #space #theartofscience

In November of 1743 a comet appeared in the sky. Within weeks it had become one of the brightest of time. It had - for reasons still unclear - six dramatic tails sweeping out from its head. Image from A Popular Treatise on Comets, 1861 #historyofastronomy #art #science #astronomy #history

Have you ever wondered why the minute has sixty seconds? Or why the day has twenty-four hours? Or why the week has seven days? The answers lie deep in the history of astronomy and have their origins more than three millennia ago... #space #historyofastronomy #science #history
