Moon-Jupiter-Saturn Conjunction

   Tuesday morning May 12th, before sunrise, the 19-day old waning gibbous Moon will be within a few degrees from the outer planets Jupiter and Saturn. All three will fit within the field of view of binoculars.

May Moon at Descending Node

   Sunday May 10th the 17-day old waning gibbous Moon crosses the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.

   On the date of the descending node the waning gibbous Moon will be above the southern horizon at sunrise and will be near the western edge of the Milky Way. However the Moon’s reflected sunlight dims out the glow of the Milky Way. To the east are 4 of the visible planets, Jupiter, Saturn, Mars. Dwarf Planet Ceres, and Neptune are also part of the line-up along the ecliptic, but both have apparent magnitudes too dim to be naked-eye visible.

Moon – Antares Conjunction

   Saturday morning May 9th the 16-day old waning gibbous Moon will be about 6-7o from the heart of Scorpius the Scorpion, the reddish star Antares.
   Joining the waning gibbous Moon will be the several of the visible planets arranged west to east starting with Jupiter, then Saturn, and Mars further east. The Dwarf Planet Ceres is also part of the planet spread but at 8th magnitude Ceres would require binoculars to see.

Moon – Spica Conjunction

   Tuesday evening May 5th the 12-day old waxing gibbous Moon will be about 7o from the blue-white star Spica in the constellation Virgo the Harvest Maiden.

   In illustrations of Virgo the star Spica represents a bundle of grasses (wheat, oats) held in her left hand.

Moon Paws (Pauses) By Leo

   Over the course of 3 days, May 1st through the 3rd the 9 to 11-day old waxing gibbous Moon will traverse the constellation Leo the Lion. On the evening of May 1st the 9-day old waxing gibbous Moon will be a few degrees from the heart of the Lion, the star Regulus. This star is at the bottom of the backward question-mark pattern forming the head of the Lion.
   Two days later, on the evening of May 3rd, the 11-day old waxing gibbous Moon will be a few degrees from the tail of the Lion, the star Denebola. This star is the eastern point of a triangle pattern with two stars further to the west, right, from Denebola.

A Starlink Satellite Swarm

   Growing up during the 1960s I often spent many evenings outside with my father watching for satellites to pass over where we lived. I learned how to differentiate between an airplane and a satellite by watching the object as it approached the horizon. An airplane lights may be followed all the way to the horizon while the reflected sunlight from a satellite appears and disappears above the horizon as the satellite moves out of and then back into the Earth’s shadow. This was the early days of satellite technology and the time of communication satellites like Telstar, as well as satellites we presumed were Russian spy satellites.
      In today’s world satellites and space exploration have lost some of the public awareness and popularity. However there are many easy to see satellites including the International Space Station, the Hubble Space Telescope, a variety of communication satellites, and most recently the Starlink Satellites.
   The Starlink is a satellite built by SpaceX for the intention of providing satellite Internet access. Initially the focus will be on satellites providing Internet connection for much of North America but with the eventual launching of around 12,000 satellites the entire globe may have satellite Internet access.
   Currently the Starlink satellites appear in groups of 50 or so and look like a string of bright pearls stretched across the sky. Watch the video below of the Starlink Satellites passing over England.
   The Starlink Satellites move rapidly compared to the ISS and the group last night, in my pictures, were around 2nd magnitude or brighter. The group moved out the northwest past the Big Dipper and Arcturus toward the southeast. The satellites appear as streaks of light because the pictures were time exposures lasting 5 or 6 seconds each.

Use the Heavens Above web site for maps and times for viewing the ISS, Starlink and other satellites.
Use the NASA ISS Sightings web site for specific viewing times and directions for your location.
Use this web site, What the Astronauts See Right Now, for a simulated view from the ISS looking down at the Earth’s surface it is orbiting over.

April Moon at Ascending Node

   Monday April 27th the 5-day old waxing crescent Moon will be crossing the plane of the ecliptic moving north. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit, and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   While the waxing crescent Moon is at its ascending node further to the west, lower than the Moon, is the planet Venus.
  

   Does our Moon actually go around the Earth as many graphics show? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*
