Rebecca researches the stuff that flows out of Galaxies AKA ‘Galactic Outflows’ … and she looks across the majority of the history of the universe from right now and right back through time to less than a billion years after the Big Bang. Rebecca uses spectroscopic data from Hubble, JWST … the Awesome James Webb Space Telescope and the VLT, the Very Large Telescope which consists of a optical array of four 8.2 m telescopes high up in the Atacama desert in Chile. From these data, Rebecca is creating new understandings of how Galaxies evolve, filling in some of those gaps in our knowledge, and her Honours and PhD students are in multiple research groups on related quests to understand galactic evolution. Now, when not doing Astrophysics. Rebecca can most likely be found bike riding or playing violin … and she's currently a violinist

Moon Phases: November 5 - the Last Quarter Moon is Sunday, good time for evening skygazing. November 7 - The Moon is at apogee, when it is furthest from the Earth November 13 - New Moon, good time for skygazing the entire night. November 14 - The very thin ‘day old’ moon is near Mercury in the west just after sunset. A genuine challenge to catch this. November 20 - First Quarter Moon, great binocular moon gazing time, with Saturn nearby. November 22 - The Moon is at perigee, when it is closest from the Earth. November 25 - Jupiter is only 2 degrees away from the waxing moon. November 27 - Full Moon. Evening Sky: Saturn is nice and high in evening skies and always a joy to observe in the north. On 23 November, Saturn casts its deepest shadow over its rings …. well worth a look, or a photo. Jupiter is bright all night long all the month, and on November 2 - Opposition of Jupiter, Mercury returns to evening skies from mid-month onwards, and easily visible in the west towards the end of the month. Morning S

Today’s special episode is from your host, Brendan O’Brien, and is all about ­­the amazing James Webb Space Telescope: “Unveiling the Cosmos” Our story begins in a remote, microscopic corner in the vast expanse of the cosmos, where humankind has always yearned to uncover its deepest mysteries. The James Webb Space Telescope (JWST) represents a monumental leap in our quest to explore the universe. From its conception as an ambitious dream in the early 1990's … to its launch on Christmas Day 2021, … it’s successful deployment and calibration has resulted in the mind-boggling imagery that it is constantly beaming back down to us; the JWST has already been a testament to human ingenuity, perseverance, and the unquenchable pursuit of new knowledge. This is for our regular listeners, new listeners, space enthusiasts, and those with a curious heart.

Show Notes: Morning Sky Two beautiful bright planets will reward those who get up early in the mornings this month. Jupiter is is rising before midnight but is still best in the morning sky, it is close to the Moon on October 1 and on the 29th. Venus is moving from crescent to half moon phase and climbs higher the morning twilight coming very close to the bright star Regulus by weeks end. Partial penumbral lunar eclipse on October 28 is difficult to observe in central Australia and impossible in eastern states, but is fully visible from WA where the maximum eclipse is at 5:13am. The Moon occultation of the Pleiades (the 7 Sisters, not far from the bright star Aldabaran between about midnight and 01:24 am on 31 October depending on your location. Stars & Constellations Scorpius is setting in the west. Sagittarius is still a feature The globular cluster M22 is always worth catching Southern Cross is also a great feature to view. The LMC is reasonably high in the sky, and there is a move to have the Magell
