Well, forget what I said, turns out you can process marsrover images on the train too :) There is a super faint smudge where comet 3I/Atlas should be. The new orbit parameters in Stellarium are a pretty good match. 🔭 #3iatlas

QUINTA-FEIRA 13:30 AUDITÓRIO PRINCIPAL A Outra não quer que você divulgue e participe.

Sabe aquelas canecas com temas astronômicos que a gente sempre quis ter? Elas agora existem e vão pra XLVIII Reunião Anual da Sociedade Astronômica Brasileira em Caxambu - MG!

Tem (mais de um!) cometa no céu e estamos preparando um guia completo pra você observar! Logo mais em www.ceuprofundo.com

Como funcionou as oficinas do @ceuprofundo.bsky.social para produção de imagens com dados do telescópio espacial Hubble? Confira tudo nessa segunda parte da entrevista em nosso podcast: open.spotify.com/episode/5Hio...

Capturando os primeiros raios do Sol pra começar bem o dia. (O dia começou bem antes, observando Vênus e Júpiter!)

Paul Dirac (1902, discovered the relativistic equation for fermion wave functions), Ernest Lawrence (1901, invented the cyclotron), and Roger Penrose (1931, developed global view of spacetime and much of what we know about spacetime singularities) were all born #OTD. Pretty good day for physics. 🧪 ⚛️

Atendendo a pedidos, temos canecas!

A estrela mais próxima do Sist. Solar não é visível a olho nu! Na verdade, nem ao telescópio é fácil encontrá-la. A estrelinha indicada pelas setas é Proxima Centauri, a menor estrela no sistema Alfa Centauri e a mais próxima de nós, depois do Sol. Fizemos essa imagem com um telescópio Seestar S50.

O Telescópio Espacial Hubble fez sua primeira observação do cometa interestelar 3I/ATLAS. A cabeleira aparece claramente na imagem capturada com a Wide Field Camera 3, evidenciando a natureza cometária do objeto. imagem: STScI/HST/D. Jewitt. Processamento: Wandeclayt M./Céu Profundo

Just looked up his mass-energy equivalence paper. It's half a page long!

Physicist Kenneth Bainbridge was born #OTD in 1904. He used mass spectrometetry to verify Einstein’s mass-energy equivalence, built Harvard’s cyclotron, and directed the Manhattan Project’s Trinity Test. After that first atomic blast, he said to Oppenheimer “Now we are all sons of bitches.”

I’m not a paleontologist, but anyone saying any version of “actually having a code of professional ethics is bad because it stops me from doing whatever I want” is someone that you don’t need to ever listen to again

A barred spiral galaxy, observed with the Apache Point 2.5m Telescope in the SDSS survey. It is at redshift 0.059 (lookback time 819.8 million years) with coordinates (175.78616, -3.69634). 43 volunteers classified this galaxy in Galaxy Zoo 2.

Hubble dug up a galactic time capsule! 🕰️ Globular clusters such as NGC 1786 seen here are spherical collections of tightly-bound stars. They are very stable and long-lived, preserving stars from the earliest stages of a galaxy’s formation. Read more 👉 esahubble.org/images/potw2... 🔭 🧪

New paper on interstellar comet #3I/ATLAS is out on arXiv! By Darryl Seligman and more. Images show a fuzzy tail, and the comet's dusty coma is similarly reddish like the other interstellar comet 2I/Borisov. arxiv.org/abs/2507.02757 ☄️🔭🧪

OK, looks like 3I/ATLAS is a comet! If it were an asteroid the image would be symmetric circles. The distortion is likely due to ices sublimating to form a gaseous tail.

🔭 Tomorrow Earth is at aphelion, the farthest point in its orbit around the Sun. It's a great time to photograph the Sun to show it looks a bit smaller when we are farther away. If you combine it with an image taken at perihelion (when it is closest) you get this:

ATel #17263: Interstellar Interloper C/2025 N1 is Active astronomerstelegram.org?read=17263 -- by David Jewitt and Jane Luu

Fizemos imagens do cometa interestelar C/2025 N1 (ATLAS), ou I3/ATLAS, utilizando um telescópio robótico no Chile. Leia mais: www.ceuprofundo.com

Acordar 4 e meia da manhã pra ir uns 106 km da minha casa pra dentro do mato coletar água que infiltra no solo, fazer monitoramento de carbono e como ele afeta os nutrientes no solo em diferentes cenários de CO2 da atmosfera … pra vir um fudido dizer que mudança climática é narrativa.

ESA's astronomers are actively tracking 3I/ATLAS, which is now the third confirmed interstellar comet to pass through our Solar System! More info at: www.esa.int/Space_Safety...

New Horizons is so far away that the nearest stars have shifted markedly from where we see them on Earth. With the NH observed positions for two stars, from NH imagery alone we can figure out where the spacecraft is. This technique would be used on interstellar voyages. arxiv.org/abs/2506.21666

Work I did in 2016 to recover the "pluto-light" illuminated hemisphere of Charon. Using New Horizons' LORRI camera, we had to look close to the Sun, which filled the camera with strong and highly-structured scattered light. PCA on an ensemble of images allowed it to be modeled and subtracted.
