If you happen to be in Kentucky in late February, you may want to visit Thomas More University’s Observatory for a special lecture on astronomy. The lecture is titled “Please Stop Letting Astronomers Name Things,” and it will occur on Saturday, February 21st at 6pm.
Here is the write up for the talk:
From planetary nebulae to spaghettification, astronomers have a long tradition of giving confusing, misleading, or downright silly names to serious physical phenomena. This talk takes a humorous tour through the best and worst examples of astronomical naming. Along the way, we’ll see how names can clarify ideas, confuse students, and occasionally make astronomers cringe.
There was a time when Stonehenge was believed to be a kind of “Neolithic computer.” Archaeology has since corrected that misconception. Today, the evidence points strongly in another direction: to an arid hill in the Casma Valley on Peru’s northern coast, about 200 miles north of Lima.There stands Chankillo, a complex built around 250 B.C.E., considered the earliest known solar observatory in the Americas and the clearest known example of a monument designed to track the sun’s position throughout the entire year, according to a study in Science. Modest in appearance and largely absent from tourist posters and classic postcards, Chankillo has renewed attention as archaeologists report preliminary findings from ongoing excavations.
With a space station medical evacuation safely completed, NASA is focused on two challenging missions proceeding in parallel: launching four astronauts on a flight around the moon, at the same time as the agency is planning to send four replacement astronauts to the International Space Station...The Artemis 2 mission and Crew 12’s planned space station flight present a unique challenge for NASA. The agency has not managed two piloted spacecraft at the same time since a pair of two-man Gemini capsules tested rendezvous procedures in low-Earth orbit in 1965. The agency has never flown a deep space mission amid another launch to Earth orbit.
One of the most vivid portraits of “reborn” black hole activity – likened to the eruption of a “cosmic volcano” spreading almost one million light-years across space – has been captured in a gigantic radio galaxy. The dramatic scene was uncovered when astronomers spotted the supermassive black hole at the heart of J1007+3540 restarting its jet emission after nearly 100 million years of silence.
Note: Please ignore the previous posting for today about the Apollo 17 mission. It’s a good story, but I will need to retell it at another time (that is, on December 19th).
Using observations from the James Webb Space Telescope (JWST) and the Atacama Large Millimeter Array (ALMA), researchers found that a growing supermassive black hole can slowly starve a galaxy rather than destroy it outright.The galaxy, catalogued as GS-10578 and nicknamed Pablo’s Galaxy, existed just three billion years after the Big Bang. Despite this early stage in cosmic history, it is enormous – around 200 billion times the mass of the Sun. Most of its stars formed between 12.5 and 11.5 billion years ago, indicating a rapid burst of star formation before the galaxy suddenly shut down.
Astronomers may have discovered a previously unknown type of astronomical object, nicknamed “Cloud-9,” that could shed light on dark matter, one of the biggest mysteries in the universe. …Cloud-9 is thought to be a dark matter cloud that could be a remnant of galaxy formation from the early days of the universe, according to new research published Monday in The Astrophysical Journal Letters.
The first crewed moon mission in more than 50 years remains on track to launch as soon as Feb. 6. NASA announced on Friday evening (Jan. 9) that it plans to roll the Space Launch System (SLS) rocket and Orion spacecraft that will fly the Artemis 2 moon mission out to the pad for prelaunch checks on Jan. 17, weather and technical readiness permitting.

This week’s image comes from the Planetary Society’s recent competition to find the best space exploration images. It shows the Virgo galaxy cluster, which was the winning entry. The image was released on June 23, 2025 by the Vera C. Rubin Observatory located in Chile.
The Virgo galaxy cluster is comprised of anywhere between 1,300 and 2,000 galaxies. What you can see in this image is an impressive array of galaxies, some of them intertwined. How many different worlds within this cluster may be peering back at us? Of course, the Virgo galaxy cluster is 65 million light-years away, so the image of the Milky Way appearing on their telescopes right now was from the time when dinosaurs still walked on the Earth.
The Thirty Meter Telescope (TMT) was conceived more than two decades ago as the largest and most advanced telescope in the Northern Hemisphere. However, the telescope has encountered significant roadblocks, from funding uncertainties — now heightened by President Trump’s proposed budget cuts — to local resistance to building the telescope on Mauna Kea, a volcanic mountain in Hawai‘i that’s sacred to native communities. Now, the telescope might find a new home in La Palma on the Canary Islands of Spain. In July, the Spanish government offered to host the telescope, with an investment of up to €400 million ($460 million) to help cover some of the costs. In a brief statement posted on November 11th, the TMT announced that it is officially considering the move to La Palma.
In its latest shakeup to the Commercial Crew Program, NASA announced on Monday it has reduced the number of missions Boeing is required to fly to the International Space Station and changing the next flight from a crew mission to a cargo mission. The original contract NASA awarded to Boeing and SpaceX called for each to fly an uncrewed demonstration flight to the ISS, followed by a crewed demo mission and then conduct six regular crew rotation missions.
In the airless, radiation-saturated void outside of the International Space Station, researchers tested whether a common moss species known as Physcomitrium patens could survive at all, and if it could, for how long. The answers are yes and probably forever if it wants...Tomomichi Fujita, the study’s lead author, thinks moss could last up to 15 years in space, knowledge that could help build future extraterrestrial farms or entire ecosystems on the Moon or Mars.
