Some heavenly events are worth getting up early for – or maybe staying up late for.
Early risers and/or night owls on Flag Day (Wednesday), given the fine weather and clear skies, will be treated to a beautiful “celestial tableau” low in their eastern sky as the brilliant planet Jupiter hovers close to the right of a slender planet. waning crescent moon; They are by far the two brightest objects visible in the early morning sky and will immediately attract attention wherever the sky is clear enough.
Jupiter currently rises about two and a half hours before the sun — around 3 a.m. local noon time — when at magnitude -2.1, it eclipses everything but the moon (negative magnitude indicates the presence of a bright object in the sky). The gas giant is currently in the constellation Aries, and will remain there for the rest of the year. In the coming days and weeks, Jupiter will rise earlier and appear brighter as Earth accelerates in its orbit, closing the distance between our two worlds. Although Jupiter is as bright as ever right now, when it is in opposition to the Sun in early November, it will appear to shine twice as bright..

Pale light
Wednesday morning found the moon, 14% bright and located two degrees from Jupiter. Your thumb held at arm’s length measures about 2 degrees, so on Wednesday morning you can expect to find Jupiter, shining like a brilliant silvery “star” with steady light, will be standing about “a thumb’s length” to the right of the moon.
This view will likely be further enhanced by the “Earthshine” effect on the moon. It’s an effect that lets you see the full moon, its dark parts glowing with a gray hue interspersed between the sunlit crescent moon and the not-much-darker sky. This vision is sometimes called “the old moon in the arms of the young moon.”
Leonardo da Vinci (1452-1519) was actually the first to recognize it as Earth Rays, faint bluish-gray light from the Earth that is reflected back to the moon. Earth’s light is of course a reflection of sunlight, so earth’s light is actually sunlight reflected from the earth to the moon and reflected back to the earth.
Binoculars will highlight the effect of Earth’s rays more than the naked eye and will provide a three-dimensional effect on the moon. In some binoculars, you can even place the moon and “Big Jupiter” in the same field of view – a sight worth getting an early look at!
If you need new optics to help you see views like this, our guides to the best binoculars and best telescopes are a good start.
And if you want to take photos of the night sky, check out our guides on how to photograph the moon, as well as the best cameras for astrophotography and the best lenses for astrophotography.
Don’t forget the Galileo moons!
And while you’re using binoculars — or even better, maybe a small telescope — be sure to look for the famous Galilean satellites; the four large moons surrounding Jupiter were first seen by Galileo through his crude telescope in 1610. On this morning, if you look at Jupiter through binoculars or a telescope, you will be able to see all four satellites.
You’ll find three satellites on one side of Jupiter — coming off the big planet, Io, Europa, and Calisto — while on the other side, on its own, will be a fourth satellite, Ganymede.
So, including our month this morning, you’ll get five months for the price of one month!
