The 365 Days of Astronomy

Astronomers using the Gemini North telescope have captured the eroding remains of more than 100 dwarf galaxies as they transition into ultra-compact dwarf galaxies, objects with masses much greater than star clusters yet much smaller than dwarf galaxies.    In this podcast, NOIRLab’s Dr. Eric Peng discusses what these galaxies tell us about the formation of ultra compact dwarf galaxies.  Bios:  - Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. - Eric Peng is an Astronomer at NSF's National Optical-Infrared...

According to satellite cataloger Jonathan McDowell, there are now 18 satellite constellations, like Starlink, being planned. These constellations will contain 543,811 satellites.    This is a whole lot of missions to try and keep from colliding and all it takes is one particularly bad collision to transform the more than half-million objects from useful technologies to a shield of shrapnel that protects our universe from us by trapping us here.    In our closer look today, we are going to look at early warning systems that are being developed, and how future - more highly...

Recorded live 29 June 2023. Gravitational waves play a cosmic symphony as they pass through our galaxy. This week, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center released the results of 15 years of data in a set of papers published in The Astrophysical Journal Letters. This research is the first evidence of gravitational waves at very low frequencies.   The team, comprised of 190 scientists, transformed our region of the Milky Way Galaxy into an immense gravitational-wave antenna using pulsars. NANOGrav's endeavor involved collecting...

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: - Every year asteroid hunters discover about a hundred objects which are larger than 450 feet in diameter and come closer than 20 times the Moon's distance from us. We call these potentially hazardous asteroids. In 2015 my group the Catalina Sky Survey discovered 21 of them. It was thus exciting news to our team, when, recently, our newest team member Greg Leonard discovered three of them in rapid...

Some slight changes to Saturn and Jupiter in the sky, the start of a big change for Venus, and even more rocks fall from the sky this December here on the Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare.  Let’s start by talking about the naked eye planets visible this month, the lunar phases, and then the meteor shower and other events, so you can plan ahead better than me.    13th/14th – Geminid Meteor Shower – A VERY good year for this shower, as there is only a thin crescent Moon which sets early.  So get out there and...

In today’s episode, we’re going to look at everything from how past Earth couldn’t support photosynthesis because the days were just too short, to current Earth letting us get hit by more Cosmic Rays prior to Earthquakes going off, and to supernovae threatening our world while alien stars eat other planets. Science, sometimes, is just kind of violent.

The story of how black holes, especially young ones, grow so fast and become massive, even supermassive, has been puzzling astronomers for a long time. 

 

Well, enter VERA! – the state-of-the-art Japanese network of radio telescopes operated by NAOJ, the National Astronomical Observatory of Japan. It recently gifted astronomers with a significant clue to the puzzle.
