Astronomy Cast Ep. 682: Ultra-Diffuse Galaxies & Dark Matter
Streamed live on May 15, 2023. Astronomers first noticed the strange behaviors of rotating galaxies almost 100 years ago, suggesting there’s an invisible dark matter hold them together with gravity. Or maybe we just don’t understand how gravity works at the largest scales. Observations are much better now, and astronomers have found examples of galaxies that are almost entirely made of dark matter. Does this tell us anything?

Travelers in the Night Eps. 675 & 676: Nuking An Asteroid & Cloud 7
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: - Tonight, even though the chances are extremely slim, an asteroid hunter could find a sizable asteroid on a collision course with planet Earth. If we have decades warning, the potential impactor's arrival time could be changed by impacting the dangerous object with a high velocity mass or if we have less time we will need to nuke it which will either blow it to bits or give it a rocket like push. - To give you an idea of the asteroid traffic in our neighborhood, on a mostly cloudy night, through holes in the clouds, in a space of less than 2 hours, my Catalina Sky Survey teammate Richard Kowalski posted 7 new close approaching asteroid discoveries on the Minor Planet Center's Near Earth Object Confirmation Page.

Astronomy Cast Ep. 681: Kilonovae
Streamed live on May 7, 2023. In 2017, astronomers detected the gravitational waves and electromagnetic radiation from colliding neutron stars. This had been long theorized as one of the causes of a certain type of gamma-ray burst. By studying the event and its afterglow, astronomers have learned a tremendous amount about the formation of the heaviest elements in the Universe.

Today's 2 topics: - On December 25, 2017, while searching for Earth approaching asteroids in the constellation of Virgo, the Universe gave my Catalina Sky Survey teammate Greg Leonard a Christmas present in the form of a comet which now bears his name: P/2017 Y3 (Leonard). - In the future one can envision a space mining family boarding a descendent of the SpaceX Falcon Heavy Launch Vehicle for a trip into low Earth orbit. A few hundred miles above the Earth's surface they would rendezvous with their asteroid mining spacecraft which will be their home for the next five years or so.

NOIRLab - Catching A Star Devouring A Planet

NOIRLab - Catching A Star Devouring A Planet
By studying countless stars at various stages of their evolution, astronomers have been able to piece together an understanding of the life cycle of stars and how they interact with their surrounding planetary systems as they age. This research confirms that when a Sun-like star nears the end of its life, it expands anywhere from 100 to 1000 times its original size, eventually engulfing the system’s inner planets. Such events are estimated to occur only a few times each year across the entire Milky Way. Though past observations have confirmed the aftermath of planetary engulfments, astronomers have never caught one in the act, until now. Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. Dr. Kishalay De is a NASA Einstein postodoctoral fellow and (subsequently) MIT Kavli Institute postdoctoral fellow at the Massachusetts Institute of Technology. Kishalay works with wide-field imaging surveys on the ground and in space to discover cosmic fireworks from stellar binaries in our Galaxy and in the distant Universe. Using panchromatic follow-up facilities, he tries to understand the role of stellar cataclysms in shaping the unvierse as we "see" it in light and "hear" it in gravitational waves. Kishalay obtained his PhD in Astrophysics from the California Institute of Technology in 2021, under the supervision of Mansi Kasliwal. As part of his thesis, he served as the data pipeline lead and helped commission Palomar Gattini-IR, the first wide-field infrared time domain survey to study dust obscured eruptions in the Milky Way. Using the Zwicky Transient Facility wide-field optical time domain survey, he helped construct the largest volume-limited sample of nearby supernovae to study faint and fleeting explosions from the eruptions of helium shells on white dwarfs and births of neutron stars in compact binary systems. Previously, Kishalay obtained my undergraduate degree in Physics from the Indian Institute of Science in 2016, working with Yashwant Gupta and Prateek Sharma on high time resolution studies of radio pulsars.

Cheap Astronomy - Dear CA #92: Sex in Space!
Things that make you go hmmm. How bad is gender bias in space? In a perfect world, special consideration of women in space would be unecessary. There would just be consideration about generic humans where we might ponder a range of physical differences. Can you, you know, get it up in space? In terms of the sheer mechanics involved, the key point here, at least for the male half of the equation, is whether can you get it up in space. This is not to discount the vitally important role played by women in the overall transaction, but if the guys can’t get it up, the rest of the process does become a bit problematic.

Awesome Astronomy - Why Does the Moon Shine?
Paul Hill, Ralph Wilkins and Dr. Jenifer “Dr. Dust” Millard host. Damien Phillips, John Wildridge and Dustin Ruoff produce. From Jan 14, 2022. In this show we look at what makes the moon shine, why the moon looks different every night and how objects from dust and asteroids to stars and galaxies either reflect or emit their own light. This is a tour around the solar system and the universe to see what these objects are and how they tick.

Astronomy Cast Ep. 680: Rogue Black Holes
Streamed live on May 1, 2023. Last week we talked about rogue stars. This week we’re going to take things up a notch and talk about an even more extreme event. Rogue black holes. Astronomers recently discovered a supermassive black hole on an escape trajectory, leaving newly forming stars in its wake. It’s wonderful, terrible, nightmare fuel.

Travelers in the Night Eps. 671 & 672: Long Winter’s Nights & Meteor Whispers
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: - Long Winter nights with good seeing, from start to finish, are those on which the asteroid hunter makes new discoveries while being treated to views of millions of stars, gas clouds, and galaxies which inspire a child like sense of wonder. - Recent scientific studies have begun to shed light on the interesting mystery of how the small number of what we now call electrophonic meteors produce simultaneous light and sound. If you are lucky you could hear a meteor's dying whispers and could even be the first person to record these sounds on your cell phone.

Guide To Space - Will the Universe Run Out Of Energy?
From Mar 30, 2015. It seems like the good times will go on forever, so feel free to keep on wasting energy. But entropy is patient, and eventually, it'll make sure there's no usable energy left in the Universe.

Astronomy Cast Ep. 679: High(per) Velocity Stars
Streamed live on Apr 24, 2023. Most stars in the Milky Way are trapped in here with us, doomed to orbit around and around and around. But a few have found a way out, an escape into the freedom of intergalactic space. How do stars reach escape velocity, never to return?

Travelers in the Night Eps. 669 & 670: Seeds (356) & Laser Surfing (364)
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: - When a fleet of interstellar spaceships leaves our solar system for a planet circling a nearby star the most important of all of the riches that human explorers will carry with them will be libraries of our planet's DNA and the seeds of plants. They are the connection between past life, the inorganic world, and future life. - When we find a planet which appears to have the chemical signs of living organisms in its atmosphere, the desire to take a close up look at it will be hard to contain. Laser propelled ultra light space probes could be sent to explore nearby worlds. The cost of investigating our planetary life hosting neighbors is likely to be less than what the US is planning to spend upgrading its nuclear weapons.
