About this listen

 Astrophiz "Exceptional Interviews with exceptional scientists." Brendan sometimes even gets how and why science works, and each month he conducts in-depth interviews with leading astro and space researchers. In each episode we feature Astrophysicists, Space Scientists, Particle Physicists, Data scientists, Antenna engineers, Instrument scientists, optical & radio astronomers, Satcomm engineers, project leaders and aurora hunters. For Astrophotographers, also each month we also hear from Dr Ian ‘Astroblog’ Musgrave who tells us when, where and what to look for in the sky over the coming weeks and explains astronomical phenomena in ‘Ian’s Tangent’. This ongoing series has taken us through the history, theory and practice of radio astronomy from Faraday to Gravitational waves. Each episode includes the latest news roundup in this golden age of astrophysics. Enjoy! (& donate if you wish to help keep this podcast ad-free)All rights reserved Science

    July SkyGuide: Moon Phases: July 3 - 1st Quarter Moon Note: July 4 - Earth is at aphelion (furthest) with respect to our sun July 5 - Moon at apogee (furthest from earth)) July 10 - Full Moon July 18 - Last Quarter Moon - Ideal Stargazing July 20 - Moon at perigee (closest to eart) July 25 - New Moon - also ideal Stargazing Evening Skies: Mercury is high in the early evening twilight July 3 - Mercury close to the Beehive cluster (in binoculars) Mars is getting lower in the North-west, and close to the crescent moon on 28 and 29 July. Morning Skies: Uranus (in binoculars) near to the Pleiades cluster Venus is falling back to the horizon, and is a distinct half-moon shape and is near Uranus 3-6 July Towards the end of the month, Venus comes close to Jupiter. Saturn is very high in the morning sky and near Neptune (in binoculars) TCoronaBorealis still hasn’t gone nova, so keep watching it, A new Nova V472 Lupi is now visible in the constellation Lupus, just above the constellation Scorpius, it’s quite obvious if you age a chart and binoculars (see Ian's ‘Astroblogger’ website for the chart) Occultation of Antares on July 8 (best seen in Perth) Southern Delta Aquariid Meteor shower peaks 3am in the NE five handspans west of Saturn on the morning of Sunday July 31st ( active 12 July - 23 August) Ian’s Tangent: Observing the Dark Emu and understanding how different cultures record ‘dark constellations’. Ian's Astrophotography Challenge: ‘Backyard Astrophysics’ Capturing Nova V472 Lupi, and recording how it fades over time.

    May 31 2025
    Astrophiz 215: Dr Ian Musgrave’s June SkyGuide Summary: Mars close to thin crescent moon. Occultation of Antares behind the moon in the early evening sky. The moon comes close to some of the bright planets. … and Mars is close to the moon again at the end of the month. Moon Phases: June 3 ~ 1st Quarter Moon, and another time to catch the ‘Lunar X’ late in the night, about 11pm for Australian Eastern states. 10:30 for central states and 9pm in the West. Lunar X Tip: take an image each 1/2 hour from moonrise. June 7 ~ Apogee, furthest from earth June 11 ~ Full Moon June 19 ~ Last Quarter Moon ~ ideal for stargazing June 23 ~ Perigee, closest to earth June 25 ~ New Moon ~ ideal for stargazing June 21 ~ Solstice: shortest day in Southern Hemisphere. longest day in Northern Hemisphere Evening Skies: Jupiter is lost into the twilight Mercury returns to evening skies mid-month, on the 27th it’s 3°from the moon an hour after sunset, and will continue to be excellent until mid-July. Mars is low in the NW evening skies, and is still readily visible T Coronae Borealis is visible in late evening skies and still has not ‘Gone Nova’ so the challenge is still … to capture a Nova before and after it blows! This Nova iswell ‘overdue’ so all eyes are on it! Tuesday 10 June ~ The Occultation of Antares by the Moon is easily seen in binoculars and telescopes (for times, check Ian’s Astroblogger website) Also June is a great opportunity to see The Dark Emu in the south, the Southern Cross and the magnificent globular cluster Omega Centauri is also at it’s highest in the south. Morning Skies: Venus is furthest from the sun on 1 June, and is a half-moon shape in telescopes, and beside the crescent moon on 22 June Saturn is climbing higher in the morning sky, Scorpius is a feature in the dark morning sky in the east Saggitarius and the Heart of the Milky Way are also rising, a good opportunity to catch the Triffid and Lagoon nebulas in Saggitarius. Ian’s ’Tangent’ Ian discusses long-lived aspects of Indigenous astronomy like The Eagle, Stingray and Dark Emu, and how Western constellation names have changed over time. eg Argo was declared obsolete in 1930. Ian’s Astrophotography Challenges: 1. Capture The Occultation of Antares on June 10th (almost full moon) 2. Then on a dark night with no moon, have a go at The Dark Emu, with your mobile phone/DSLR/camera, conveniently at 8pm in the south near Scorpius, the Pointers and the Southern Cross. Tips: Use your device's highest ISO (ASA) Under urban skies, take 10 x1second exposures, and stack them using a free stacking program or app. Under dark skies, you can take longer exposures If stacking in RAW, do a ‘dark frame’ subtraction If stacking in JPEG, don’t use dark frame subtraction.
