KSC-05pd2614
KENNEDY SPACE CENTER, FLA. - At their consoles in the Atlas V Spaceflight Operations Center on Cape Canaveral Air Force Station, members of the New Horizons team take part in a dress rehearsal for the launch scheduled in mid-January. New Horizons carries seven scientific instruments that will characterize the global geology and geomorphology of Pluto and its moon Charon, m...

Welcome to a Comet, from Lander on Surface
The Philae lander of the European Space Agency Rosetta mission is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two images from the lander CIVA camera confirm. One of the lander three feet can be seen in the foreground.

Astrophotography captures a remarkable alignment as the Moon descends behind a lava fountain during an eruption at Mount Etna. This visual juxtaposition highlights the scale of volcanic activity on Earth relative to our celestial neighbor. The intensity of the molten spray reaches hundreds of meters, illustrating the immense geothermal pressure within Italy’s most active stratovolcano while the lunar backdrop provides a distinct perspective on planetary synchronization and optical depth.

The (simulated) progressive ejection of magnetic fields from galaxies (via galactic winds and/or AGN feedback) into the cosmic web, in a large ENZO cosmological simulation run on LEONARDO at CINECA.
The red colors mark the baryon matter distribution while the green colors mark the magnetic field amplitude, averaged along the line of sight.

The Soul Nebula, officially designated as Westerhout 5, serves as a profound example of a stellar nursery located approximately 6,500 light-years away in the constellation Cassiopeia. This vast emission nebula is characterized by towering clouds of gas and dust shaped by the intense stellar winds and ionizing radiation from embedded clusters of massive, young stars. Through narrow-band imaging, astronomers can isolate the specific emissions of hydrogen, sulfur, and oxygen, providing critical data on the chemical composition and thermal processes driving star formation within these cosmic structures. Examining such regions allows for a deeper understanding of the lifecycle of stars and the dynamic evolution of the interstellar medium.

The provided image offers a specialized view of the Lagoon Nebula, also known as Messier 8, with its stellar inhabitants digitally removed to enhance the visibility of its internal structures. Located approximately 5,000 light-years away in the constellation Sagittarius, this immense interstellar cloud serves as a site of active star formation. By isolating the nebular gas and dust, astronomers can more clearly observe the intricate ridges, globules, and filaments sculpted by high-energy radiation and intense stellar winds. This perspective highlights the complexity of the interstellar medium and the delicate fluid dynamics involved in the birth of new stars.

A new astrophysical model suggests that Venus lacks a moon not because one never formed or was destroyed by a catastrophic impact, but because the planet's exceptionally slow rotation and gravitational pull caused any potential moon to spiral inward and crash into the surface.

New research group by a dear former colleague now at the Institute of Astronomy, Bulgarian Academy of Sciences in Sofia: Cometary Life Cycle (CLIC) led by Rosita Kokotanekova ...
... is looking for two PhD students and two Postdocs to study the physical evolution of comet nuclei and their links to other small body populations (TNOs, Centaurs, irregular moons, and dormant comets). The project is also closely linked to Comet Interceptor and Rubin Observatory’s LSST.
More at https://clic.kokotanekova.com/positions
Rosita adds: "I know Bulgaria is not a traditional top destination for young researchers, but this is a well-funded opportunity for independent, curious candidates open to the adventure." Deadlines to apply to go on this adventure are September 30 for the PhD students, and October 31 for the Postdocs.

KSC-06pd0084
KENNEDY SPACE CENTER, FLA. — Into a blue, cloud-scattered sky, NASA’s New Horizons spacecraft lifts off on time at 2 p.m. EST aboard an Atlas V rocket from Complex 41 on Cape Canaveral Air Force Station in Florida. This was the third launch attempt in as many days after scrubs due to weather concerns. The compact, 1,050-pound piano-sized probe will get a boost from a k...

The annual Perseid meteor shower often faces significant celestial interference when coinciding with a full moon. In August 2022, the Sturgeon Moon created a bright lunar background that reduced the visibility of fainter meteors by decreasing the visual contrast of the night sky. Despite this natural light pollution, the most luminous Perseids remained visible to observers and cameras, demonstrating the intensity of debris originating from Comet Swift-Tuttle as it intersects Earths orbital path. This intersection highlights the complex relationship between lunar cycles and observational astronomy.
