EVSN - Catch the (Alien) Rainbow
The 365 Days of Astronomy
From Thursday, April 25, 2024. As scientists discover and explore the atmospheres of more and more planets orbiting stars other than our Sun, we are learning that if you can imagine it, it probably exists. In a new paper discussing the planet WASP-76b, researchers describe what appears to be a giant iron glory in the atmosphere of another world: a circular rainbow, and it's not caused by refracted starlight!

Astronomy Cast Ep. 717: Understanding the Ages of Distant Cosmic Objects
The 365 Days of Astronomy
Streamed live on Apr 22, 2024. How old is that star? That planet? That nebula? Figuring out the ages of astronomical objects is surprisingly challenging. Fortunately, astronomers have developed a series of techniques they can use to work out the ages of stuff. This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit Jeanette Wink Siggi Kemmler Andrew Poelstra Brian Cagle David Truog Ed David Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and...

Travelers in the Night Eps. 725 & 726: Mtn Ops & Close Space Rocks
The 365 Days of Astronomy
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: - My team, the Catalina Sky Survey, would not find a single asteroid without Steward Observatory's Mount Lemmon Operations, or Mtn Ops for short. Bottom line is that Mtn Ops does whatever it takes to make our Asteroid Hunting facilities continue to function. - Since 1900 there have been 11 close approaches by asteroids larger than 300 feet in diameter. One of them, the Tunguska Object was about 400 feet in...

The Cosmic Savannah - Ep 56: Our Supermassive Black Hole
The 365 Days of Astronomy
Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama. The Event Horizon Telescope (EHT) Collaboration has unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy! This is the first direct evidence of the black hole in our galaxy. The image was produced by a global research team called the EHT Collaboration, using observations from a worldwide network of radio telescopes. We are joined by Dr. Iniyan Natarajan who is a postdoctoral fellow at the University of Witwatersrand and who was part of the team of over 300 astronomers who made this...

SETI Live - SETI Artist In Residence Program: Xin Liu’s Inward Expeditions
The 365 Days of Astronomy
Nimbly combining the tools of art and science, SETI Institute Artist in Residence Xin Liu expresses what it means to be human through a diverse body of work that includes frost-coated sculptures, a bubbling fountain of crude oil, and a performance in outer space. In a new body of sculptures exhibited at Pioneer Works in New York City, the artist considers her fears around having her eggs frozen, creating warped, skeletal, frost-covered sculptures that propose a human body transformed through a cryogenic process. Through art, Liu centers the human experience in the face of...

Today's 2 topics:
- A faint shooting star or meteor streaking across the sky is produced when a tiny bit of rock or dust enters the Earth's atmosphere and burns up some 60 miles above us. NASA scientist Dr. Marc Fries and his collaborators have used Doppler Weather Radar to track twenty meteor's dark trails through the sky. In the past year or so they have used this technique to direct searchers on the ground to the probable location of freshly fallen meteorites.
- In 2015 the Earth was struck by at least 43 meteoroids which created bright fireballs. Their arrival does not seem to be correlated with the position of the Earth in it's orbit about the Sun.Overall a given piece of ground on Mars is several times more likely to be hit by a space rock than is a similar sized area on Earth.
