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

    Astrophiz221 - September SkyGuide
    Sep 1 2025
    September Moon Phases: September 8 - Full Moon and Total eclipse of the moon around 2am for those who will be getting up very early to see it (Best viewed in WA) September 8 - Saturn close to the Full Moon (4° apart) in evening sky (also close during the Lunar eclipse in the early hours of the morning.2am central max 4am. wa has best view 2am max 3am September 10 – Moon at perigee (closest to earth) September 14 – Last Quarter Moon – Ideal for Stargazing September 22 – New Moon – ideal for Stargazing all night September 26 – Moon at apogee (furthest from earth) September 30 – 1st Quarter Moon September Highlights: Mars is still in the early evening North-Western skies. 1 September - ‘The Eyes of Clavius’ shadow effect on the moon is visible September 20 - Venus very close to Regulus in the morning twilight (0.5° apart) and close to the thin crescent Moon (4° apart). Will need binoculars and a level horizon September 17 - Jupiter near crescent moon September 22 - Earth at Equinox 29 September - ‘Luna X’ is quite visible for about 4 hours in the early evening starting on the East Coast from 6:45pm, Central States from 5:25pm and on the West Coast from 4:45pm ======================== Evening Skies: Mars is still in the early evening North-Western skies, setting around 9pm Saturn at Opposition (biggest and brightest) and very nice viewing in evening skies from now till late October. TCoronaBorealis still hasn’t gone nova, so keep watching it, ======================== Morning Skies: Uranus in the morning twilight Venus is falling in the east as the month progresses and gibbous in shape Jupiter is climbing higher in morning skies in the east ======================== Ian’s Tangent: A 3rd interstellar comet visits our system, and its tail is pointing in the wrong direction! . Arriving from the direction of the constellation Sagittarius, the interstellar comet has been officially named 3I/ATLAS. And Ian introduces us to the nature of cometary ‘ices’ as revealed by spectroscopy, and the chemical/metal composition of Comet 3I/ATLAS. The comet, 3 Km in diameter, poses no threat to Earth and will remain at a distance of at least 1.6 astronomical units (about 150 million miles or 240 million km). It is currently about 4.5 au (about 416 million miles or 670 million km) from the Sun. 3I/ATLAS will reach its closest approach to the Sun around Oct. 30, at a distance of 1.4 au (about 130 million miles or 210 million km) — just inside the orbit of Mars. The interstellar comet’s size and physical properties are being investigated by astronomers around the world. 3I/ATLAS should remain visible to ground-based telescopes through September, after which it will pass too close to the Sun to observe. It is expected to reappear on the other side of the Sun by early December, allowing for renewed observations. ======================== Ian’s Astrophotography Challenge: Capture the Lunar Eclipse Top Tip: As the eclipse progresses you will need to adjust your exposure settings as the brightness of the moon changes.

    Astrophiz220-Dr Emil Lenc-Imaging Radio Skies
    Aug 14 2025
    Today we're bringing you a fabulous interview with an amazing astrophysicist, Dr. Emil Lenc, who works on commissioning new capabilities on telescope arrays like the ATCA, the MWA, ASKAP, and the beautiful new SKA-Low Array over in the harsh scrublands in outback Western Australia, which is part of the multi-billion dollar Square Kilometer Array He has some great stories and insights into this golden age of radio astronomy.

    Astrophiz219-August SkyGuide
    Jul 30 2025
    Astrophiz Astronomy 219 ~ Dr Ian Musgrave’s August SkyGuide & Astrophotography Challenge August Moon Phases: August 1 - 1st Quarter Moon August 2 - Moon at apogee (furthest from earth) August 9 - Full Moon August 15 - Moon at perigee (closest to earth) August 16 - Last Quarter Moon - Ideal for Stargazing August 23 - New Moon - also ideal for Stargazing August 30 - Moon at apogee again! (furthest from earth) August 31 - 1st Quarter (Blue) Moon again! 'Luna X’ is quite visible in early evening on August 1st 3 August - Occultation of 2 Scorpii and 3 Scorpio by the moon Evening Skies: Mars is fading, but obvious in the Western evening sky, setting around 9PM 3 August - Mars and Beta Virginis are extremely close ( <1° apart) 12 & 13 August: Saturn rising very close ro the waning Moon 26 August: Mars near to thin crescent Moon (just 4° apart) Morning Skies: All of August: Saturn is lowering close to Neptune (1-2°) in morning sky 3 & 4 August:Venus close to star Propus (𝝶 Geminorum, 1°) 19 August - Lineup of Jupiter, Venus and Mercury 20 August: Jupiter near crescent Moon (6° apart) 5:45am East 21 August: Venus near thin crescent Moon (7° apart) TCoronaBorealis still hasn’t gone nova, so keep watching it, Two Novae are currently observable in Southern Skies. Nova V462 Lupi is still 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) Nova V572 Velorum A nova has erupted in the constellation of Vela, the sail. Known as Nova V572 Velorum it is faint (around magnitude 5.7-5.8, at the unaided eye threshold) and may be glimpsed by those with good visual acuity under dark sky conditions. However, it is best with binoculars of a small telescope. It is well placed for southern hemisphere observers and visible from the early evening on. It is close to the Southen Pelaides (Theta Carina) and the eta Carina nebula.
