In this episode of Astronomy Daily (S05E125), hosts Anna and Avery cover six major stories from the frontiers of space science and astronomy, including the most detailed image ever taken of the Milky Way's core, a Hubble discovery that solves a decades-old cosmological mystery, the oldest confirmed asteroid impact crater on Earth, a pair of impossibly light exoplanets, an impending lunar impact from a SpaceX rocket stage, and a live solar weather alert for Southern Hemisphere aurora watchers. Stories Covered Story 1 — Euclid's Record Milky Way Galactic Bulge Image: ESA's Euclid telescope releases the largest, highest-resolution visible-light image ever made of the Milky Way's central bulge, containing more than 60 million stars. The image serves as a baseline for NASA's upcoming Roman Space Telescope's microlensing survey. (ESA / NASA, June 24–25 2026) Story 2 — Hubble Catches Galaxy Clearing the Cosmic Fog: Galaxy MXDFz4.4, observed 1.4 billion years after the Big Bang, has been caught emitting ionising ultraviolet light — direct evidence of how the early universe's hydrogen fog was cleared. Published in The Astrophysical Journal, June 23 2026. Story 3 — Earth's Oldest Asteroid Crater Dated to 3 Billion Years: Curtin University researchers precisely date the North Pole Dome impact structure in Western Australia's Pilbara region to 3.024 billion years ago — the oldest known impact crater on Earth, beating the next oldest by ~800 million years. Published in Geology, June 23 2026. Story 4 — Super-Puff Planets Lighter Than Cotton Candy: An Oxford-led international team confirms TOI-791 b and c — two Jupiter-sized exoplanets with densities lower than cotton candy (0.038 and 0.047 g/cm³), making them the lowest-density giant planets ever found. Published in Monthly Notices of the Royal Astronomical Society, June 26 2026. Story 5 — SpaceX Falcon 9 Upper Stage to Impact Moon on August 5: A spent Falcon 9 upper stage from the January 2025 Blue Ghost / Hakuto-R launch is on course to strike the Moon near Einstein Crater on August 5 2026. Visibility from Earth is uncertain, but NASA's LRO will image the resulting crater. NASA SSERVI, June 2026. Skywatching — A G1 geomagnetic storm struck overnight June 25, with further unsettled conditions expected June 26–27 as coronal hole streams strengthen and new sunspot region AR4478 rotates into Earth view. Aurora possible for Tasmania, New Zealand's South Island and southern Australia tonight.Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.
