Hubble Space Telescope returns to the Crab Nebula after 25 years, documenting its rapid expansion (about 5.5 million km/h) and the evolving filaments driven by a central pulsar wind and synchrotron radiation, not just shock waves. The 2024 observations deepen our understanding of this supernova remnant, with findings published in The Astrophysical Journal.
Scientists used advanced synchrotron imaging to reveal detailed 3D models of 200-million-year-old dinosaur embryos, uncovering new insights into their development, including the presence of two types of teeth and skull similarities to modern reptiles, providing valuable clues about early dinosaur evolution.
Astronomers have discovered a new Odd Radio Circle (ORC), ORC J0219–0505, using the MeerKAT radio telescope in South Africa. This massive circle of radio light, associated with the elliptical galaxy WISEA J021912.43–050501.8, is 371,600 light-years wide and differs from previously discovered ORCs, suggesting a selection bias in earlier detections. The origins of ORCs remain unknown, with theories suggesting they result from shockwaves caused by cosmic collisions or merging supermassive black holes. The discovery highlights gaps in current astronomical knowledge and the need for further research.
