## Resource

Astronomy Daily · S05E153 · Wednesday 29 July 2026. Four stories from the frontier of space and astronomy, plus a both-hemispheres look at the sky — and news of our brand-new website. In this episode • Betelgeuse is not alone. ESO’s VLT/SPHERE has captured the clearest direct image yet of Betelgeuse B, the long-suspected companion to the famous red supergiant — ending a roughly century-long search. Published 28 July 2026 in Astronomy & Astrophysics (Montargès, Boccaletti et al.). The companion is more massive than predicted (≈2–3 solar masses), likely paces Betelgeuse’s ~6-year brightness cycle, and may eventually spiral into the supergiant. • Swift catches a wandering black hole. TDE 2025abcr — the most off-centre tidal disruption event ever seen — reveals a ~1-million-solar-mass “wandering” black hole ~30,000 light-years from its galaxy’s core, ~750 million light-years away. First flagged by the Zwicky Transient Facility (Nov 2025) and pinned down with NASA’s Swift; an AI sifted ~500,000 nightly flashes to find it. Published 27 July 2026 in The Astrophysical Journal Letters (Stein et al.; Carney et al.). • Roman is fuelled for launch. NASA’s Nancy Grace Roman Space Telescope completed fuelling on 25 July (≈290 gallons of hydrazine) and holds its mission-preview briefing today — one month from a 30 August launch, roughly eight months ahead of schedule. Roman will survey ~50× as much sky as Hubble in five years, probe dark energy, and is expected to find 100,000+ exoplanets via microlensing. • Swift’s rescue mission is in trouble. Katalyst’s LINK servicing spacecraft — launched 3 July to boost the decaying Swift observatory — began spinning over the weekend; two of three reaction wheels are non-operable, with some cold-gas thruster degradation. LINK remains powered…
