What do we see after the new Moon phenomenon?

The new Moon phenomenon appeared on January 13 last. And, while the great combination of Jupiter and Saturn is over, they’re still close together in the sky. Then, Jupiter and Saturn will form a cluster near Mercury shortly after sunset.

New moons occur when the Sun and Moon have the same ecliptic longitude, a condition also known as a union. Last December, the people of South America had the opportunity to admire the new Moon coinciding with a total eclipse. However, that phenomenon did not happen this time. Because, the Moon will “miss” the Sun as it passes.

The reason we don’t see monthly eclipses is because the Moon’s orbit is about 5 degrees tilted relative to the plane of Earth’s orbit. So this time all we see is just a dark sky. People cannot see the Moon from Earth because the illuminated side is on the other side.

On the evening of the New Moon, January 12, the sun sets at 4:50 pm New York time. As the Sun sets, Jupiter, Saturn and Mercury are all seen as the sky darkens, forming a rugged line in the southwest from left to right. Mercury is farthest to the left, then Jupiter, then Saturn.

All three planets will stretch about three degrees in the azimuth (horizontal direction). This means that the distance between Mercury and Saturn would be about six diameters of the Moon.

In order to see the trio, the essentials are good weather and a flat horizon. All three of these planets are bright enough to be seen before Saturn sets at 5:33 p.m. New York p.m. Jupiter dives 13 minutes later and Mercury “disappears” at 5:51 pm.

Mercury is often a difficult planet to observe because it is close to the Sun. And, it is often difficult to recognize Mercury in the first minutes after sunset. But this time, the new Moon is easier to detect because it passed 2 degrees south of Mercury on January 14.

This combination won’t be visible from New York as it happens at 3:14 am Easternly. However, after the sun sets, the thin crescent Moon will still be just east of Mercury and form an easy signpost to the planet.

Meanwhile, Venus continues its tenure as a morning star, which grows at 6:13 a.m. East. The sun appeared at 7:18 am on January 13. Venus moves closer to the Sun each day. And, at the end of the month, Venus will appear only about half an hour before sunrise.

The winter constellations are becoming more vibrant than ever for Northern Hemisphere observers this January. Around 5 pm, the Orion branch was completely above the eastern horizon.

And, one can observe that its stars appear as the sky darkens. The Orion branch faces Taurus in the west and north. Meanwhile, looking to the right and up, everyone could see the Hyades cluster. Looking left, the constellation Gemini will be easy to see on top of the branch.

The stars have been resolved through spectroscopy. Although they cannot be seen with the naked eye, astronomers can separate the light of these stars into component colors.

Each star has a characteristic spectrum, with colors indicating which elements are present. In the 19th century, astronomers noticed that the spectrum seemed to represent more than one star. And in the early 20th century it was confirmed that, in fact, four stars were shown.

The new Moon phenomenon will be the “start” of a series of astronomical events that are expected to be expected this year. Scientists predict two of the brightest planets in the sky – Venus and Jupiter, will appear side by side at dawn February 11.

This phenomenon, called congestion, describes a state when two planets are very close together in the sky when viewed from Earth. On this occasion, on the far right hand side of the pair of planets, viewers can also see Saturn not far away.

For the most favorable viewing period, observers should start 20-30 minutes before sunrise. Viewers in the Southern Hemisphere will have an ideal opportunity to contemplate, because two planets from the point of view in this area will be further away from the Sun and higher in the sky.

Meanwhile, on March 9-10, it will be the convergence of the four celestial bodies. This is an exciting occasion when a global astronomer can witness 4 celestial bodies appear very close together in the sky. Mercury, Jupiter, and Saturn will lie roughly in line, next to the not far three, the crescent Moon.
