  1. Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made them interested in astronomy in the first place. That seems to be the case for the authors of …

  2. On May 20th, 2024, an iceberg measuring 380 square kilometers (~147 mi2) broke off the Brunt Ice Shelf in Antarctica. This event (A-83) is this region’s third significant iceberg calving in the past four years. The first came In 2021, when A-74 broke off the ice sheet, while an even larger berg named A-81 followed …

  3. Four zebrafish are alive and well after nearly a month in space aboard China’s Tiangong space station. As part of an experiment testing the development of vertebrates in microgravity, the fish live and swim within a small habitat aboard the station. While the zebrafish have thus far survived, they are showing some signs of disorientation. …

  5. In just a few short years, NASA hopes to put humans back on the lunar surface. The first moonwalk in more than 50 years is scheduled for no earlier than September 2026 as part of the Artemis III mission. In preparation, astronauts, scientists, and flight controllers are conducting simulated spacewalks here on Earth. “Field tests …

  6. The search for life in the Universe has fascinated humans for centuries. Mars has of course been high on the list of potential habitats for alien existence but since the numerous spacecraft images that have come back showing a barren landscape, it seems Mars may not be so habitable after all. That is, until recently. …

  7. The Universe wants us to understand its origins. Every second of every day, it sends us a multitude of signals, each one a clue to a different aspect of the cosmos. But the Universe is the original Trickster, and its multitude of signals is an almost unrecognizable cacophony of light, warped, shifted, and stretched during …

  8. The parade of interesting new exoplanets continues. Today, NASA issued a press release announcing the discovery of a new exoplanet in the Gliese 12 system, sized somewhere between Earth and Venus and inside the host star’s habitable zone. Two papers detail the discovery, but both teams think that the planet is an excellent candidate for …

  9. I love the concept of a ‘puffy’ planet! The exoplanets discovered that fall into this category are typically the same size of Jupiter but 1/10th the mass! They tend to orbit their host star at close in orbits and are hot but one has been found that is different from the normal. This Neptune-mass exoplanet …

  10. It’s been 20 years in the making, but a 3200-megapixel camera built especially for astrophysics discoveries has finally arrived at its home. The Legacy of Space and Time (LSST) camera was delivered to the Vera C. Rubin Observatory in Chile in mid-May, 2024. The camera traveled from its construction lab at the SLAC National Accelerator …
