Radio Astronomy Podcast: 60 years since Yuri Gagarin's flight
April 2021 marks 60 years since Yuri Gagarin became the first human being to travel into space. In this month's episode we look back on Yuri's historic flight, how it all nearly went wrong, and the mission's lasting legacy.
SKAO is born
The SKA Observatory, a new intergovernmental organisation dedicated to radio astronomy, was launched on 4 February 2021 following the first meeting of the Observatory’s Council. Known as SKAO, it is the world’s second intergovernmental organisation to be dedicated to astronomy. Hear from SKAO Council Chair Dr Catherine Cesarsky and SKAO Director-General Prof. Philip Diamond on the significance of the day's events.
NRAO 2020 Highlights: The Very Large Array Measures the Wind Speed of Brown Dwarfs
Astronomers have used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and NASA’s Spitzer Space Telescope to make the first measurement of wind speed on a brown dwarf — an object intermediate in mass between a planet and a star. Writing and narration provided by Phil Plait @SYFY Discover more about the wind speed of brown dwarfs from the original press release: https://public.nrao.edu/news/brown-dwarf-wind-speed/

A new (alien?) signal designated Breakthrough Listen Candidate One (BLC-1) appears to have originated from Proxima Centauri, the closest star to our solar system. It's already being compared to the famous WOW! signal of 1977, but it's very likely not really coming from Proxima, or even from beyond our solar system. But, it could nevertheless be a significant milestone in the search for extraterrestrial intelligence, or SETI. 00:00 Start

Can We Put a Radio Telescope on the Far Side of the Moon? With Saptarshi Bandyopadhyay
An ultra-long-wavelength radio telescope on the far-side of the Moon has tremendous advantages compared to Earth-based and Earth-orbiting telescopes, particularly a Lunar Crater telescope can observe the universe at wavelengths greater than 10m (i.e., frequencies below 30MHz), which are reflected by the Earth’s ionosphere and are hitherto largely unexplored by humans. John Michael Godier speaks with Saptarshi Bandyopadhyay about his 2020 NIAC finalist project for putting a radio telescope inside a crater on the far side of the moon. Link:

Radio Burst Detected on Earth, We Don't Know Where It Came From!
On April 28th this year, Astronomers recorded a powerful radio signal coming directly from our Milky Way galaxy. It is coming from a distant Magnetar, SGR 1935 which was spotted by different telescopes by NASA. NASA recorded 200+ bursts in just 20 minutes. Magnetars are a different type of Neutron Stars. They are well known for their enormous magnetic field which can be 1,000 times stronger than Neutron Star. Since 2007 we've found many radio bursts but their actual source is still not so clear. What If A Neutron Star Hits The Earth?

Center of the ALMA Array
Working together, the separate ALMA telescopes become one giant telescope up to 11 miles (16 km) across. That's a huge, light-gathering eyeball! At that size, ALMA can pinpoint small, hidden details deep inside galaxies or within giant star forming regions, making it one of the most powerful telescopes ever made. In the heart of the array sits the 16 East Asian MELCO telescopes working together like one telescope of 492 feet (150 m) across. Called the Morita Compact Array, these specialized 7-meter telescopes can map the Universe's giant, wispy structures, making certain that ALMA never misses the forest for the trees.

https://public.nrao.edu/explore/alma-explorer/
The ALMA Holography Tower
Former North American ALMA Project Director Dr. Adrian Russell talks about the shaping of ALMA's telescope dishes. Every ALMA telescope dish was precision-shaped on site to ensure that its reflection surface is a near-perfect parabola. We use holography towers to read the bumps on a telescope dish, and then engineers make adjustments by hand to reshape the surface. By pointing the antennas at one of the two 50-meter high holography towers at the OSF, a special holography receiver on the antennas can help create a map of the surface of the antenna to identify imperfections. Throughout the life of the observatory, an antenna will be brought down from the high site and re-calibrated in this way about every five years.

Behind the Technical Building at the ALMA Operations Support Facility
Behind the Technical Building are the vehicle garages and the maintenance facilities for telescopes and transporters. This area bustles when routine equipment maintenance schedules kick in. The OSF not only serves as the location for operating the Joint ALMA Observatory, it is also the Assembly, Integration and Verification (AIV) station for all the high technology equipment before being moved to the Array Operations Site (AOS).

Ya-Hui Yang (NCU): Hard X-ray and Radio Signatures Associated with Intense Solar Flares
Solar flare is one of the most explosive phenomena in the solar system that large amount of energy (1032~1033 ergs) releases within 102-103 seconds, which can accelerate electrons up to few hundreds of MeV and ions up to several tens of GeV. One of the most important issues in solar physics is to investigate the energy release and particle acceleration processes. The flare-accelerated particles generated in the corona can propagate upward along the open magnetic fields into the interplanetary space and move along the closed magnetic fields downward to the lower solar atmosphere. In general, the chromospheric hard X-ray sources occur in the impulsive phase of solar flares and are thought to be the footpoints of newly reconnected magnetic fields mapped to the primary energy release site. The radio emissions are the important diagnostic tool to trace and study the dynamics of flare-accelerated particles. In this talk, I will first introduce the solar flare characteristics in multi-wavelength observations. Then I will present the research works on the estimation of reconnection electric field, asymmetry of chromospheric hard X-ray emissions, fine structures seen in a radio dynamic spectrogram, as well as the pre-flare Type III radio bursts and their solar associations. 8/19 (Wednesday) 14:20 - 15:20

The Far Side Of The Moon Is The Perfect Place For a Radio Telescope
We’ve now passed the 50th anniversary of the Apollo 11 landing, and all eyes are back on the Moon. NASA is planning to return to the Moon by 2024 with its Artemis mission, the Chinese have put the Moon firmly in their plans for space exploration, and even SpaceX thinks the Moon is the perfect destination to test out the capabilities of its Starship. But what can you do with the Moon? Refuel spacecraft with resources drawn from the lunar regolith? Mine its helium 3 for your fusion reactors? Build a lunar amusement park? In fact, the far side of the Moon might make one of the best platforms we have for radio telescopes. One side of the Moon is completely blocked from Earth’s constantly increasing radio traffic, giving it the perfect view to the most sensitive radio signals in the Universe. Our Book is out!

54th Annual Jansky Lecture with Professor Anneila Sargent
Expanding Horizons with Millimeter/Submillimeter Astronomy. Only a few decades ago, millimeter-wave astronomical images were limited by the sizes of single telescopes. Today’s images from the Atacama Large Millimeter/submillimeter Array (ALMA) are dramatically more detailed, thanks to its extended horizons. For example, observations of the disks of gas and dust that surround many very young stars are providing unexpected insights into the way planetary systems form. Dr. Sargent will discuss some of the implications of these results and expectations for the future. She will also explore the path from those single telescopes to larger arrays, touching on how her personal journey has been influenced.
