From April 6, 2020. Tokyo Institute of Technology researchers have published a model that seems to explain Uranus' bizarre tilt - a collision between a young Uranus and a massive ice world that could have both tipped Uranus over, and also formed its rings and its 27 moons in the process.   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!

https://www.youtube.com/watch?v=OEZu3pXAFWY Hosted by Fraser Cain. From Jan 31, 2020. In 2006, astronomers spotted the telltale sign of a supernova detonating in the galaxy NGC 1260, located about 240 million light-years away in the constellation of Perseus. As telescopes around the world turned their collective light-gathering power on the expanding explosion designated as SN 2006gy, they realized they were seeing something very unusual.   This clearly wasn't a regular supernova. It grew to be 100 times brighter than the typical stellar explosion and lasted much much longer.   More than a decade after that cosmic explosion, astronomers finally think they know what series of events led to the release of this much energy, now called a superluminous supernova. A red giant ate a white dwarf. An event so rare it probably accounts for only 1 in 1,000 supernovae!   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!

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 From December 2025. Today's 2 topics: - The Dark Energy Camera on the National Science Foundation's Blanco 4-meter telescope on Cerro Tololo in Chile is taking near Sun twilight images to search for asteroids, hidden in the glare of our Sun, sneaking up on home planet.   - Just before noon on September 1st of 1859 Richard Carrington and Richard Hodgson were making sketches of clusters of sunspots when they were nearly blinded by an intense solar flare. 17.6 hours later a geomagnetic storm thought to be caused by a solar coronal mass ejection traveling at some 1,500 miles per second slammed into the magnetic field surrounding our home planet. We missed being hit with a such large coronal mass ejection by only 9 days in July of 2012. Next time we might not be that lucky.   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!

Scientists at NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science, have submitted an unprecedented set of asteroid detections to the IAU Minor Planet Center, including hundreds of distant worlds beyond Neptune and 33 previously unknown near-Earth asteroids. In this podcast, Dr. Mario Juric discusses how these asteroids were discovered and what we can look forward to in the future from the Rubin Observatory.    Bios:  Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. Prof. Mario Juric is the P.I. of UW's contribution to the construction of the Rubin Observatory, Senior Fellow at UW's eScience Institute, and director emeritus of UW's Institute for Data-intensive Astrophysics and Cosmology (DiRAC). Once fully operational in 2026, the Rubin Observatory will deliver the largest sky survey in the history of mankind, answering questions from the nature of Dark Energy to discovering potential "killer" asteroids. Prof. Juric led the definition of Rubin data products and oversees the solar system team. Prof. Juric received his PhD in astrophysical sciences from Princeton University and was a postdoctoral fellow at the Institute for Advanced Study and a Hubble Fellow at Harvard University. His research is in the area of data-intensive survey astronomy and AI. He developed a range of astronomical software products and techniques, including software for asteroid detection, mapping the Milky Way, novel astronomical databases, and cloud-based astronomical data analysis systems. Prof. Juric discovered what was at the time the largest known structure in the Universe (the Sloan Great Wall; with J. Richard Gott), a dwarf galaxy colliding with the Milky Way (the Virgo Overdensity; with Z. Ivezic), and over a hundred asteroids (including 22899 Alconrad, the smallest known main-belt binary asteroid; with Korado Korlevic). A Jupiter-family comet 183P/Korlevic-Juric is named after him.   Links: NOIRLab Press Release NOIRLab social media channels can be found at: https://www.facebook.com/NOIRLabAstro https://twitter.com/NOIRLabAstro https://www.instagram.com/noirlabastro/ https://www.youtube.com/noirlabastro   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!

[email protected]   Observer's Calendar for May 2026 on Episode 533 of the Actual Astronomy podcast. I'm Chris and joining me is Shane. We are amateur astronomers who love looking up at the night sky and this podcast is for everyone who enjoys going out under the stars. — David Nagler Question show reminder.    2 Full Moons! May 1 - Full Moon — Carbon Star RY Mon best in evening May 2 - Alpha CVn Colourful Double May 3 - Antares 0.5-degrees N of Moon May 4 - Carbon Star X CnC best in evening May 6 - Eta Aquaria Meteors best in predawn skies but 3/4 Moon interferes May 7 - Markarian's Chain well placed  Key Details of Markarian's Chain: Location: Situated in the constellation Virgo, between the stars Denebola and Vindemiatrix, part of the larger Virgo Cluster. Key Members: The chain is anchored by the large elliptical galaxies M84 and M86. Other notable members include NGC 4477, NGC 4473, NGC 4461, NGC 4458, and NGC 4438. Observation: The brightest members are visible in small telescopes, but it is a popular target for astrophotography in the spring, often requiring a wide field of view to capture the entire string. Interaction: While some galaxies are randomly aligned, at least seven members share a common physical motion. The pair NGC 4438 and NGC 4435, known as "The Eyes," are actively interacting and distorting one another. May 8 - 2 Shadows on Jupiter Ganymede & Europa 8:44pm EDT Eastern North America May 9 - Last Quarter Moon — NGC 4147 well placed May 10 - Lunar Curtis X visible May 11 - NGC 4038/4039 well placed Key Facts About NGC 4038/4039: Location: Constellation Corvus, the Crow. Distance: Generally estimated between and million light-years. Other Names: Caldwell 60/Caldwell 61, the Antennae Galaxies, NGC 4038/4039. Discovery: Found by William Herschel in 1785. Interaction Type: Colliding/Merging galaxies. Appearance: The collision produces long tidal tails of stars, gas, and dust resembling insect antennae May 12 - Mare Orientale May 13 - NGC 5634 well placed May 15 - Ganymede & Europa shadows visible on Jupiter 11:19 pm EDT May 16 - New Moon but Old crescent in east before Sunrise today.
