Mars is now half-way across the southeastern predawn sky from Saturn and Jupiter, and is getting farther away from the pair with each day. Mercury and Venus appear low on the northwestern horizon at sunset – the crescent Moon appears near the star Pollux on May 26th. The Moon appears the star Regulus high in the west-southwestern sky after sunset on May 28 and 29th. The Moon then appears near the star Spica, high in the southern sky after sunset on June 1st. Asterisms galore in the east-northeastern sky at midnight this week: the Summer Triangle, the Northern Cross and the Mini-Cassiopeia – which I didn’t know was a thing… now I’ll have to go look for it! The Moon is a waxing crescent – visible toward the southwest in early evening. The first quarter Moon occurs on Friday May 30th – visible high in the southern sky in the early evening. After May 30th, the Moon will be a waxing … Continue reading →

When it comes to astronomy, asteroids are pretty much my favorite subject; the Sun comes in #2 by a wide margin. I have a presentation about the Sun that I’ve given numerous times – I’m modifying it to present remotely to my wife’s middle-school science students, and creating a worksheet based on my presentation. Here’s me giving my Sun presentation to the Warren Astronomical Society before the total solar eclipse of 2017: I’ve also suggested to my wife that she show the following videos to her science students: Mars continues to pull away from Saturn and Jupiter in the southeastern predawn sky; the Moon joins the early morning planets from May 12-15th. Mercury appears low on the northwestern horizon at sunset this week. Venus appears a bit lower each evening on the northwestern horizon after sunset. Comet C/2019 Y4 (ATLAS) will be north of Venus and the star Capella, but may require binoculars or a telescope to see. The Moon … Continue reading →
The beginning of the 20th century saw several occurrences that had a profound effect on the field of astronomy: worldwide construction of large and complex telescopes designed specifically for photographic imaging; the on-going Carte du Ciel international astronomical project, with the Vatican Observatory contributing thousands of photographic plates; Albert Einstein and his theories of special relativity, published in 1905, and general relativity in 1915 – forever changing the way we look at the cosmos; women acting as human “computers” who took part in several great astronomical discoveries, many only recently receiving the credit they are due. Exactly a hundred years ago, in the 1920s, the size of the universe was a major source of debate among astronomers. At the time, it was unknown if there was only one galaxy, and if the “spiral nebulae” astronomers had cataloged resided within that galaxy, or if they were many galaxies in their own right – much farther away. The debate brought into focus … Continue reading →
Libraries across the U.S. are looking for online presentations by NASA/JPL Solar System Ambassadors and NASA Night Sky Network members; my wife is having me give my presentation about the Sun (and possibly a tour of the solar system using SpaceEngine) to her science classes using Google Hangouts Meet. If you are an astronomy presenter and you have the equipment to present remotely, you may want to contact libraries and schools in your area to see if they would like you to do an online presentation. Mars continues to pull away from Saturn and Jupiter in the southeastern predawn sky; the Moon joins the early morning planets at the beginning of next week. Venus appears a bit lower each evening at dusk in the western sky. Early next week, comet C/2019 Y4 (ATLAS) will be in the same general region of the sky as Venus, however it will probably not be as spectacular as the depiction in the image below. … Continue reading →
I’ve been having a pretty rough time since the recent loss of my brother – thank you for the kind thoughts. I’ve been an avid computer gamer ever since the first computer games existed; I’ve recently started playing No Man’s Sky, a futuristic space exploration and survival game with more worlds than I could explore in my lifetime – it’s providing the distraction my mind needs right now. The conjunction of Mars, Jupiter and Saturn continues in the southeastern predawn sky – Mars has pulled far away from Saturn and Jupiter. Venus appears in the western sky at dusk accompanied by Betelgeuse and Capella. The Moon appears between the stars Regulus and Pollux high in the southwestern sky after sunset on April 30th, and very near the star Regulus on May 1st. The Moon is a waxing crescent, visible toward the southwest in early evening. The first quarter Moon occurs on May 1st, it will be visible high in the … Continue reading →
I lost my brother Victor to COVID-19 on April 12th. Please, everyone take precautions and stay safe! The triple-planet conjunction of Mars, Jupiter and Saturn continues in the southeastern predawn sky. Venus, Aldebaran and Rigel form a temporary triangle asterism in the western sky at dusk. The Moon appears near Aldebaran on the evening of April 25th, and near Venus the next evening. The star Vega and the constellation Lyra appear above the northeastern horizon at midnight. The Moon is a waning crescent, visible low to the east before sunrise. The new Moon occurs on April 23rd. After April 23rd, the Moon will be a waxing crescent, visible toward the southwest in early evening. Moon News Made in isolation, depicting isolation.

Last night, I gave the featured presentation during the Warren Astronomical Society’s online WebEx/YouTube meeting: The Challenges of Interstellar Travel. I cannot believe how much I learned putting this presentation together; honestly, there’s probably weeks more research I could do, and papers I could read. I discussed sending small probes and giant generation ships to the stars, and the enormous amount of energy, resources and manufacturing it would require. I talked about physical and mental problems related to space travel, and what it would take to keep humans alive during an interstellar voyage. I concluded my presentation suggesting maybe we should make sure all the life-support systems are functioning properly on the generation ship we all share, and are travelling through interstellar space aboard.

We were planning on having a memorial gathering for George at the University of Arizona back on St. Patrick’s day, but alas the coronavirus led to the shutdown of the University, so that event has been postponed at least until the fall. Meanwhile, however, Br. Guy has created a video to show at … Continue reading →
My wife and I have finished moving out of our home of 22 years, and are now living in her parent’s basement; we were planning on taking our time looking for a new home, but with Michigan on COVID-19 lock-down, any home-hunting plans have gone out the window. My wife’s school is having teachers interact with students via Google Classroom, and the Warren Astronomical Society held their first online “virtual meeting.” I saw a comment on a Solar System Ambassador (SSA) forum that the greatly increased streaming activity is putting a lot of pressure on the internet. In one SSA’s community, she could not connect to Skype or Facebook Live because of internet congestion. With so many communities going to telework, tele-education, etc. and also streaming HD video around the clock, the internet is very congested on a limited bandwidth. Some people cannot stream a doctor’s appointment; some doctors cannot get pages to load to refill much needed prescriptions. For … Continue reading →
