Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org Today's 2 topics: From October 2024. - 2016 was another record year for asteroid hunters during which we discovered 1,894 new Earth approaching objects. My team, the NASA funded, Catalina Sky Survey, led the pack with 931 Near Earth Asteroid discoveries. - An example that a relatively large space rock can approach the Earth suddenly started with what appeared as a bright star moving across the images that I had just obtained with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

On today's episode, we're diving into what's going on with Near-Earth Asteroid 2024 YR4. You may have heard online that this asteroid is on a trajectory to impact Earth on December 22nd, 2032. It's captured the zeitgeist and everyone's talking about it.  But what can we do in the meantime? We say - Let's learn! We need to science the $%#t out of this one! We're going to explore the idea of planetary defense, the level of impact if it does hit Earth in 2032, and how lucky we are to have successful missions like DART and HERA to lean on for our “armageddon” moment.  We'll also try to answer these questions: What is the Asteroid? What is the impact potential on Earth? How was it discovered? Why do the impact probabilities keep changing? What can we do about it? Why don't we just NUKE it? Keywords: asteroid 2024 yr4, planetary defense, impact probability, kinetic impactor, Dart mission, Hera mission, James Webb Space Telescope, automated detection, NASA funding, public interest, Tunguska event, city killer, orbital changes, nuclear option, planetary defense systems Timestamps: 00:00 Asteroid 2024 YR4 Overview and Initial Concerns 03:03 Discovery and Initial Observations 05:30 Probability Changes and Data Limitations 07:25 Public Interest and Planetary Defense 10:35 Kinetic Impactor Defense and Future Missions Here's to building a fantastic future - and continued progress in Space (and humanity)!  Spread Love, Spread Science  Alex G.

The internet is buzzing about Asteroid 2024 YR4, currently ranked as the highest-threat asteroid in our skies. But is it really cause for concern? Our Public Education Specialist, Kate Howells, breaks down the facts. Then, we shift from potential impacts to stunning space imagery as Finn Burridge from the Royal Observatory Greenwich shares how astrophotographers worldwide can participate in the Astronomy Photographer of the Year competition. Finally, our space policy experts, Casey Dreier and Jack Kiraly, discuss how the new Trump administration has impacted NASA in its first weeks. Stick around for What’s Up with Bruce Betts, as he explains how we assess asteroid threats using the Torino Impact Hazard Scale.

Second time's a charm. Chandrayaan-3 makes India the first country to reach the Moon's southern pole. Artificial Intelligence takes the pressure off … finding a Near Earth Asteroid has now gotten twice as fast… and Australia's three space launch providers have news to share. From a multi-year deal at ELA to permanent facility approval at Southern Launch and streamlining technology integration at Gilmour Space.

After their life as research subjects, what happens to lab monkeys? Some are euthanized to complete the research, others switch to new research projects, and some retire from lab life. Should they retire in place—in the same lab under the care of the same custodians—or should they be sent to retirement home–like sanctuaries? Online News Editor David Grimm joins host Sarah Crespi to discuss recently penned legislation that pushes for monkey retirements and a new collaboration between universities and sanctuaries to create a retirement pipeline for these primates. Sarah also talks with Dante Lauretta, principal investigator for NASA's Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) and a professor at the University of Arizona in Tucson, about the latest news from the asteroid Bennu. Within 1 week of beginning its orbit of the asteroid, OSIRIS-REx was able to send back surprising images of the asteroid ejecting material. It's extremely rocky surface also took researchers by surprise and forced a recalculation of the sample return portion of the craft's mission. This week's episode was edited by Podigy.

Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org Today's 2 topics: - NASA's RADAR telescopes at Goldstone, California and the Arecibo Observatory in Puerto Rico were used to obtain images of 2014 HQ124. - If 2014 LJ21 is an asteroid, its brightness suggests that it is about 1 and a quarter miles in diameter. On the other hand if 2014 LJ21 is a comet, we still know its path accurately, but don't have a good way to estimate its size.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

How exactly (and why) does a spacecraft get a "gravitational assist" from a planet en route to another planet? Where does that energy come from? The Astroquarks take a look at gravity assists and the OSIRIS-REx mission to grab some bits of a Near-Earth Asteroid and bring them back to Earth. Plus, the field of gravitational wave astronomy expanded now with the detection of a new black hole collision by two separate gravitational wave observatories. It's a weighty episode.

A conversation with John Marmie, Asteroid Redirect Mission Commercial Partnerships & Hosted Payload Lead.

In two years a Near Earth Asteroid now known as Bennu will have a visitor from Earth. OSIRIS-REx Principal Investigator Dante Lauretta reports on his mission’s successful launch.Learn more about your ad choices. Visit megaphone.fm/adchoices

The Discussion: Looking back over Sirius Astronomy outreach events in June, a bit of a rant over peer-review and science by press conference and our own pathetic attempts to get awarded a Nobel Prize or two. The News: Modelling of Pluto’s moon Charon ahead of the flyby of NASA’s New Horizons spacecraft next year, aerobraking an orbiter through Venus’ upper atmosphere and radio imaging a Near Earth Asteroid. The 5 Minute Concept: How comets are far from the traditional portents of doom and may well be the harbingers of life. The Interview: Beginning a regular series of interviews with Dr Joe Liske about each of the key facilities in the European Southern Observatory’s arsenal, starting with the 3.6 meter telescope. Q&A: Listeners’ questions via email, Facebook & Twitter take us on a journey into the astronomy issues that have always plagued our understanding or stretched our credulity. This month Ralph & Paul answer: Hey you mad martians, I have a question for the podcast. When we look at other galaxies we can clearly see the glowing bulge at their centres. Why is it when we look up at the milky way we don’t see one. Thanks for all your efforts? Lee Garner from Norwich, UK via Facebook . Should the BICEP2 team have made their announcement pre-peer review? Mark Cullen (@Mokwepa) from the Buckinghamshire, UK via Twitter .

Carl W. Hergenrother is an American astronomer. Working with the Catalina Sky Survey and other colleagues, he has co-discovered a number of comets and asteroids. These discoveries include one long-period comet, C/1996 R1 (Hergenrother-Spahr), and three periodic comets, 168P/Hergenrother, 175P/Hergenrother and P/1999 V1 (Catalina). The Asteroid 3099 Hergenrother is named after him. [source Wikipedia] presented on October 22, 2012.
