At New York’s Hayden Planetarium the place I’ve spent the final 37 years serving within the function as an Affiliate and Visitor Lecturer, currently we have been getting an rising variety of cellphone calls making mainly the identical inquiry. A typical name goes one thing like this: “I used to be out shortly after midnight final evening and couldn’t assist however discover an excellent silvery star glowing low within the east-northeast. It was far brighter than any star and I used to be simply curious to know what I used to be .”
The article in query is the biggest planet in our photo voltaic system: Jupiter. It is a welcome sight, rising within the late night and developing above the east-northeast horizon this week by 11:45 p.m. native daylight time.
And late tonight (Aug. 7) proper on into the early morning hours of Tuesday (Aug. 8) Jupiter can have firm, for hovering somewhat over 2 levels above and a bit to its left would be the final quarter or “half” moon. Your clenched fist held at arm’s size measures roughly 10 levels; so, the moon will seem lower than 1 / 4 of a fist above Jupiter in the course of the in a single day hours of Monday/Tuesday).

The king of the planets is at present positioned among the many stars of Aries, the ram. Now that dazzling Venus is hidden between Earth and the solar, Jupiter is certainly the brightest “star” within the evening sky, at present shining at -2.4 magnitude or greater than 2 and a half occasions brighter than the brightest star, Sirius.
Put merely, you’ll be able to’t miss it.
And Jupiter will solely proceed to achieve in brilliance within the coming weeks.
Jupiter will proceed to rise earlier as Earth’s movement across the solar carries us towards opposition with the large planet in early November. At that time we’ll fly between Jupiter and the solar, and they are going to be on reverse sides of the sky. So, till then Jupiter will seem to brighten additional, as a result of the space between us is steadily reducing. Presently, the planet is 40.2 light-minutes from Earth, however that is destined to shrink to solely 33.1 mild minutes by mid-autumn.
Understand that while you take a look at the moon relative to Jupiter, that our pure satellite tv for pc is barely about 1.26 mild seconds from us — or greater than 1,900 occasions nearer than the extra distant Jupiter.
Word too, that Jupiter is getting brighter and likewise wanting nice in telescopes now, although to see it at almost its highest and steadiest this week, one of the best time to look is throughout morning twilight, about 60 to 90 minutes earlier than dawn.
When you’ve got a small telescope or an excellent pair of binoculars which you could maintain regular or mount on a tripod, you may also take a look at Jupiter’s 4 massive moons, first sighted in 1610 by Galileo. Jupiter will seem like flanked by two moons on both aspect. On its jap (left) aspect, you may see (going outward from Jupiter), Io and Ganymede, whereas on the western (proper) aspect, will likely be Europa and Callisto.
And I am certain that ought to the sky be clear late Monday evening that come subsequent Tuesday I am sure to take a number of inquiries from individuals eager to know what that “UFO” was beneath the moon on Monday evening and that appeared to comply with it throughout the sky into the early hours of Tuesday morning.
At the least you now know what that “UFO” is!
And bear in mind: For those who’re on the lookout for a telescope or binoculars to watch the moon, our guides for the greatest binoculars offers and the greatest telescope offers now can assist. Our greatest cameras for astrophotography and greatest lenses for astrophotography also can enable you put together to seize the subsequent skywatching sight by yourself.
