Every Monday I pick the northern hemisphere’s celestial highlights (mid-northern latitudes) for the week forward, however make sure you verify my major feed for extra in-depth articles on stargazing, astronomy, eclipses and extra.
What To Watch For In The Night time Sky This Week: June 14-20, 2021
The Photo voltaic System at a standstill. How can that presumably be? It can’t, however it might seem that method this week as first Jupiter then the Solar seem to stop their journeys by means of our sky and cease useless of their tracks.
Jupiter in retrograde is merely a line of sight situation and never an actual factor (inform that to astrologers!) whereas Sunday’s solstice is one thing conceptual moderately than clearly seen, however studying about each occasions as you stargaze gives you a realized perspective on the wonders of our Photo voltaic System.
Summer season stargazing is right here!
Friday, June 18, 2021: First Quarter Moon
Tonight after darkish the Moon will look half-lit. In reality, the Moon is consistently half-lit by the Solar, however from right here it simply doesn’t look that method. That’s as a result of the Moon is consistently orbiting, getting farther from the Solar because it waxes to full Moon, then nearer to it because it wanes to a New Moon.
There are eight phases of the Moon; at First Quarter it rises within the east at midday and units at midnight.
Sunday, June 20, 2021: Jupiter stands nonetheless
Like all of the planets, Jupiter strikes eastward by means of the constellations. It’s at the moment in Aquarius and through its 12 years orbit of the Solar it is going to transfer by means of all the zodiacal constellations. Nonetheless, at the moment it seems to standstill—and tomorrow it is going to go “backwards,” showing to journey westwards. Jupiter in retrograde!
It’s all about perspective in fact; Earth is shifting far more shortly across the Solar than Jupiter, so from right here it simply looks as if Jupiter is shifting backwards (consider being in a rushing automotive and overtaking one other automotive—it is going to seem to go backwards).
If you wish to see the large planet, it rises within the east after midnight this week. It’s really nice information for pus planet-gazers since Jupiter—and all of the planets—seem to go retrograde a number of months earlier than Earth slides into place between them and the Solar.
That’s the second of opposition, when a planet is greatest and brightest in our evening sky. Jupiter’s opposition is on August 19, 2021.
Sunday, June 20, 2021: Summer season Solstice
Summer season solstice 2021—when the Solar reaches its highest and northernmost level within the sky, stops, and begins shifting southward—for the northern hemisphere is 03:32 tomorrow in Common Time. That interprets as 7:32 p.m. PST at the moment and 11:32 p.m. EDT.
Both method, North America will get to have fun the longest day throughout the evening. Bizarre! It’s nothing to do with day or evening for any location, however as a substitute it’s a world second when the North Pole is at its most tilt towards the Solar. Cue the longest day and shortest evening 2021.
In reality, the phrase “solstice” “comes from the Latin phrases “sol” and “sisto”—“Solar” and “cease.”
Occasions and dates given apply to mid-northern latitudes. For essentially the most correct location-specific info seek the advice of on-line planetariums like Stellarium and The Sky Stay. Test planet-rise/planet-set, dawn/sundown and moonrise/moonset instances for the place you might be.
Wishing you clear skies and huge eyes.
