In the Sky This Week – October 13, 2020

Sacred Space Astronomy avatarPosted on October 13, 2020 by Bob TrembleyOctober 13, 2020
This entry is part 168 of 180 in the series In the Sky This Week

Venus appears in the eastern predawn sky all week; the waning crescent Moon appears near Venus on the mornings of Oct. 13th and 14th. Saturn and Jupiter appear in the southern sky after sunset. Mars is at opposition – when it and the Earth are in-line with the Sun; this is also when Mars is closest to the Earth in their orbits, so now is a great time to go observe Mars! Here’s a close-up of the Mars opposition: The Moon is a waning crescent – visible low to the east before sunrise. The new Moon occurs on Oct. 16th – the Moon will not be visible at this time… unless it get’s smacked by an asteroid… The Moon returns to the southwestern sky at dusk as a waxing crescent by early next week. If you click on the Moon image above, or click this link, you will go to NASA’s Moon Phase and Libration, 2020 page – it will … Continue reading →

In the Sky This Week – June 4, 2019

Sacred Space Astronomy avatarPosted on June 4, 2019 by Bob TrembleyJune 4, 2019
This entry is part 100 of 180 in the series In the Sky This Week

Mars continues to dim in the west-northwestern sky after sunset, and Mercury appears low near the horizon all week. A thin crescent Moon appears near Mars on June 5th, and moves towards the south each day. The Moon appears by the star Regulus on June 7th and 8th. Saturn, Jupiter and the star Antares have been slowly crawling across the southern sky for several weeks; Antares sets a bit earlier each morning. Venus appears very low on the horizon just before sunrise all week. Earthshine Earthshine is visible earthlight reflected from the Moon’s night side. It is also known as the Moon’s ashen glow or as “the new Moon with the old Moon in her arm.” Earthshine is most readily visible from a few nights before until a few nights after a new moon, during the (waxing or waning) crescent phase. – Wikipedia The next few days will be the ideal time to try and catch a glimpse of Earthshine!   The Moon is a … Continue reading →

NASA Space Place: A Close-Up View of Mars

Sacred Space Astronomy avatarPosted on June 25, 2018 by Bob TrembleyJune 25, 2018

A Close-Up View of Mars By Jane Houston Jones and Jessica Stoller-Conrad In July 2018, skywatchers can get an up close view of Mars—even without a telescope! In fact, on July 31, Mars will be closer to Earth than it has been in 15 years. Why is that? Like all the planets in our solar system, Earth and Mars orbit the Sun. Earth is closer to the Sun, and therefore it races along its orbit more quickly. Earth makes two trips around the Sun in about the same amount of time that Mars takes to make one trip. Sometimes the two planets are on opposite sides of the Sun and are very far apart. Other times, Earth catches up with its neighbor and passes relatively close to it. This is called Mars’s closest approach to Earth, and it’s happening this year on July 31. The Moon will be near Mars on that night, too! Keep in mind that even during … Continue reading →

In the Sky This Week – May 15, 2018

Sacred Space Astronomy avatarPosted on May 15, 2018 by Bob TrembleyMay 22, 2018
This entry is part 44 of 180 in the series In the Sky This Week

Mars and Saturn agree that they rather like the early morning sky, and have decided to stay there forever… or so it seems… Jupiter just past opposition, is slowly leaving the morning planets and making its way towards being visible only in the evenings. I was playing with the equatorial grid feature of Stellarium and noticed how close Polaris was to the North Celestial Pole. So, of course, I HAD to see how the South Celestial Pole looked… and I noticed the the southern hemisphere doesn’t have a convenient star near the pole – which led me to find this article on the One-Minute Astronomer about how to find the South Celestial Pole. The Moon The Moon is new on the 15th, and joins Venus in the western sky near sunset as a thin waxing crescent on the 17th. The Moon will be high in the western sky after sunset on the 20th &21st. The Sun Although there is some impressive coronal loop … Continue reading →

Mars, Saturn and the Moon are in the morning sky, and Jupiter is visible all night. Venus is the evening star at dusk, and the solar wind is “dense” and fast.

Sacred Space Astronomy avatarPosted on May 1, 2018 by Bob TrembleyMay 1, 2018
This entry is part 42 of 180 in the series In the Sky This Week

The Moon appears in the southwestern predawn sky near Jupiter on May 1st, and makes it way between Mars and Saturn in the southern sky on May 5th. Ursa Major (and the Big Dipper) are in the northwestern predawn sky, and Arcturus is bright in the western sky. Venus remains low in the western sky near sunset. Jupiter can be seen rising the in the eastern sky after sunset. Jupiter will be at opposition on May 9th – its face will be fully illuminated by the Sun, and it will be visible all night long! Sidewalk astronomers from around the world do a collective dance of joy! The Moon The Moon is a waning gibbous just past full; the Moon will be at third quarter on the 8th; May 7-10th would be good days to do some early morning sidewalk astronomy at schools! The Sun The Sun has been spot-free for 2 days. There are coronal holes at both poles, and a small … Continue reading →

Mars Opposition 2016

Sacred Space Astronomy avatarPosted on May 21, 2016 by Bob TrembleyMay 21, 2016

Orbital mechanics, being what they are, means that objects orbiting closer to their parent body are moving faster than those orbiting further out: Earth being closer to the Sun, orbits faster than Mars. About every 26 months, the Earth will “catch up to and pass by” Mars. The point where the Earth and another planet are closest in their orbits is called an “opposition.” The best time to observe a planet through a telescope is during an opposition – and that’s happening RIGHT NOW with Mars (May 22, 2016). Groups and individuals across the globe will be holding public “Mars Vigils.” The NASA Night Sky Network has a list of events across the U.S., and Meetup may have listings for your area. I highly encourage everyone on planet Earth to get eyeballs to eyepieces and have a look at the red planet! NASA released this stunning Hubble image of Mars on May 19, 2016 showing cloud formations near Mars’ southern … Continue reading →

For example, people who saw the conjunction on the 21st were generally amazed. But certainly Cosmos seems to think that stuff has to be over the top.

  • Fernando Comeron January 15, 2021 at 5:07 am on JWST update – Hexagons in SpaceNice article, Deirdre -and actually hexagons in space are very common, although very tiny. Carbon hexagonal cycles are at the basis of polycyclic aromatic hydrocarbons, a class of molecules that compose the cold interstellar medium. So hexagons are pretty much everywhere in the Universe!

  • Christopher M. Graney January 4, 2021 at 10:43 am on Carols versus Matthew on the Star of WonderI should have been more clear. When I said "This sounds just like the Great Conjunction of 2020", I meant it sounds like that *kind* of thing -- something no one who was not an astronomer would have noticed it just by chance.
  • Alfred Kracher January 2, 2021 at 10:47 am on Carols versus Matthew on the Star of WonderEmbellishments of Matthew’s simple “star” into a spectacular miracle are all but irrresistible. Already in the apocryphal 2nd century Gospel of James it shines with an “incredible brilliance amidst the constellations and making them seem dim.” And over the centuries artists of all kinds have further expanded on these exaggerations,...
  • Fr. Timothy Sauppé January 2, 2021 at 5:30 am on Carols versus Matthew on the Star of WonderI thought the biggest objection to the Jupiter/Saturn conjunction being the “Star of Bethlehem” was the 800 year cycle of its occurrence viz. the timing is off.
