This is a photo from 10 days ago of stars millions of light-years away (so the picture is of things long, long before October 3).
The official credit is: ESA/Hubble & NASA, A. Filippenko,… Read the rest “Science Art: Yellow and blue, old and new, 2025”
This is a tool from Theatro del Mvndo y de el Tiempo, a book of star maps by Giovanni Paolo Gallucci, Miguel Perez, and Sebastian Muñoz. I found it in the David Rumsey Map Collection, the “Celestial”… Read the rest “Science Art: Instrumento de Geographia y Cosmographia, 1606”
Space brings us new analyses of stellar graveyards, which astronomers study to discover how stars develop and, eventually, die – turning into dense neutron stars or denser black… Read the rest “Giant black-hole binaries spinning in star graveyard”
Caltech says that, thanks to an NSF grant, they’ve found where all the dark matter has been hiding. That’s up to 50 percent of matter in the universe, the stuff that doesn’t… Read the rest “Where the dark matter hides.”
This is Venus, moving in front of the Sun. Technically, I suppose it’s a lot of Venuses, or a chain of a lot of pictures of Venus.
It was made by NASA/SDO, AIA, or NASA’s Solar Dynamics… Read the rest “Science Art: Transit of Venus in 2012.”
This is an image from The New Astronomy, a textbook of space sciences I found on archive.org.
It’s one of what was at the time the largest telescopes ever built, a reflector that used… Read the rest “Science Art: The Great Paris Reflector, 1898.”
This delightful diagram appears on a page of A New Astronomy For Beginners that also has an almanac of “Important Future Eclipses” from 1898 (January 22, East African and India)… Read the rest “Science Art: Earth’s Shadow and Penumbra in Sections, 1898.”
It was this photograph’s anniversary today, or so said Robert McNees, posting on Bluesky’s science-communication feed.
On the 29th of December, 1888, a Welsh businessman,… Read the rest “Science Art: Andromeda Galaxy, by Isaac Roberts, 1888.”

This is a photograph of a strangely-shaped galaxy, as taken by the Webb Space Telescope. Or rather, a set of “interacting” galaxies, known collectively as Arp 142. From the… Read the rest “Science Art: Interacting Galaxies Arp 142 (MIRI Image), by NASA, ESA, CSA, and STScI.”
The European Space Agency reports on the team who successfully decoded an “alien” transmission actually sent by a probe orbiting Mars as part of a multidisciplinary project… Read the rest “Daddy-daughter alien decoding.”
Mashable has the details, but the general gist is the space telescope will not focus on Sun-like stars to find Earth-like planets (that is, rocky worlds with gaseous atmospheres). Instead,… Read the rest “James Webb will be looking for other Earths in unusual places.”
Scientific American has a new explanation for the famous “Wow!” signal – the orderly burst of focused radio energy recorded in 1977 that seemed like it could possibly… Read the rest “The Wow! signal probably wasn’t aliens (but is still wow).”
PhysOrg says there’s liquid water on Mars (great!) but (aw!) it’s too far underground to tap:

BBC reports on the discovery of a cave on the moon that has awakened a primordial proto-human urge in the space scientists observing it. They spot a cave on the moon and think, hey, we could … Read the rest “There’s a cave on the moon we could live in.”
