NOIR Lab - The Largest Radio Jet In the Early Universe 03/08/2025

NOIR Lab - The Largest Radio Jet In the Early Universe Making use of the Gemini North telescope, one half of the International Gemini Observatory, astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. In this podcast, Dr. Anniek Gloudemans discusses how this object was discovered, the follow up observations and what we have learned about radio jets in the early Universe. Bios: - Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. - Anniek Gloudemans is a postdoctoral fellow at NOIRLab working on understanding the formation and evolution of the most massive supermassive black holes in the early Universe. She received her masters degree from the University of Amsterdam in 2019, including an internship at the European Space Agency in 2018. Following this, she obtained her PhD at Leiden Observatory in The Netherlands in 2023, where she studied the low-frequency radio emission of early supermassive black holes. Besides her research, Anniek has a passion for teaching and organizing outreach activities for all ages with a focus on connecting the world through astronomy and raising awareness for climate change.

Travelers in the Night Eps. 305E & 306E: Newborn Planets & Marrakech 03/02/2025

Travelers in the Night Eps. 305E & 306E: Newborn Planets & Marrakech Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. Today's 2 topics: From October 2024. - The ALMA radio telescope located in the Atacama desert of northern Chile is able to see the faint millimeter wave length glow emitted by gas molecules and dust particles in the disk of material surrounding the very young star named HD 163296. This solar system in formation is located about 400 light years away in the constellation of Sagittarius. HD 162396's age compared to our Sun is like that of a 3 day old human baby compared to a 65 year old adult. - A location 9,000 feet above sea level in the Atlas Mountains of Morocco is ideal for an asteroid hunter since the weather is often clear and the skies are dark. It was thus intriguing for me to see that a new asteroid discovery was posted from J43 which is the Morocco Oukaïmeden Sky Survey or (MOSS) located near Marrakech , a name I had not encountered except in the Crosby, Stills, and Nash song "Marrakech Express". The MOSS observatory has team members in Morocco, France, and Switzerland, call themselves amateurs, and produces professional quality results.

Last Minute Astronomer - March Episode 03/01/2025

Last Minute Astronomer - March Episode March 2025 says goodbye to Saturn, welcomes a total lunar eclipse, and continues hanging out with the rest of the planets. Hi everybody, I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. We’ll start by talking about this month’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me. 14th - Total Lunar Eclipse 1:09am EST – Partial Eclipse Begins – Just look South to find the Full Moon, and watch as the Earth’s shadow appears to nibble on the Moon from left to right. This phase will last about an hour. (You might hear that the penumbral portion of the eclipse starts before this. While true, it is essentially undetectable with the naked eye.) 2:26am EST – Totality Begins – Now the umbra of the Earth’s shadow is completely engulfing the Moon, and only the light from all the sunrises and sunsets on Earth are illuminating our orbital partner’s surface, making it appear anywhere from dark yellow to orange to red to brown. This phase will last a little over an hour, with maximum eclipse right before 3am. 3:32am EST – Totality ends, Partiality begins again – now the shadow leaves the Moon, starting to expose its surface from the right to left. 4:48am EST – Partial Eclipse Ends Other things to look for As the Moon gets darker, more and more stars will be visible The Moon is right between Leo and Virgo - Virgo is usually tough to find, so take advantage of the darkened Moon.

Travelers in the Night Eps. 303E & 304E: Dust Stories & Big Splash Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From September & October 2024. Today's 2 topics: - Collect your own beautiful micro-meteorite sample. It is estimated that several hundred thousand pounds of left over particles from the formation of our solar system enters the Earth's atmosphere every day with perhaps 10% of the of the total reaching the surface of our home planet. The individual grains of cosmic dust or micro-meteorites as they are also called range in size from the diameter of a human hair to twice the thickness of a dime. - To discover what would happen if an asteroid were to strike a large body of water, Dr. Galen Gisler led a team of scientists who used high performance computing facilities at Los Alamos National Laboratory to calculate and visualize a 3-D model of an asteroid entering the Earth's atmosphere over one of the world's oceans. These efforts won them the Best Visualization and Data Analytics Showcase award at Supercomputing 2016. Reality is that what happens depends upon the mass, size, speed, angle of approach, and composition of the impacting object. Galen's group of scientists documented the hunch that since an asteroid strikes the water at a single point, it only effects the immediate region around the impact point, whereas to create a tsunami, you need something like an under water landslide which disturbs an entire water column from the ocean floor to the surface.
