The brand new moon occurs Monday, July 20, at 1: 33 p.m. EDT (1733 GMT), on the identical day that Saturn reaches opposition. Intellectual at its brightest of the year, the ringed planet will possible be seen all evening long.
Contemporary moons happen roughly each and every 29.5 days when the moon is at once between the Earth and solar. The two our bodies portion the identical celestial longitude, an alignment furthermore referred to as a conjunction. (Celestial longitude is a projection of the Earth’s possess longitude lines on the celestial sphere.)
Because no sunlight reflects off the moon’s surface throughout this lunar section, and for the reason that new moon rises and sets end to the solar, the new moon will not be seen in the evening sky. On the different hand, sunlight mirrored off the Earth’s surface can faintly illuminate the moon’s darkish surface sooner than and after the new moon, a phenomenon identified as “Earthshine.” Whilst it is possible you’ll perchance well fair not be in a jam to see the new moon, the absence of moonlight may perchance well perchance make varied evening-sky objects less complicated to survey at heart of the evening evening sky.
Associated: The brightest planets in July’s evening sky
Contemporary moons are essential to spiritual Muslims and Jews: they mark the beginnings and ends of the months for his or her respective calendars.
The July new moon occurs to be the open of Dhu al-Hijjah, the 12th month of the Islamic calendar year, and one in which the pilgrimage to Mecca historically takes jam. For Jews it is the essential day of Av, when per the Biblical e book of Ezra, Jewish people returned to Israel after exile in Babylon.
The fully time to survey Saturn
According to NASA’s Skycal, Saturn will possible be in opposition at 5: 33 p.m. EDT (2133 GMT) on the evening of the new moon. Opposition system the planet is almost precisely on the reverse aspect of Earth’s sky as the solar. In Contemporary York City, as an instance, Saturn rises at 8: 17 p.m. and the solar sets at 8: 22 p.m. local time. No longer fully will Saturn be well-positioned for viewing all evening long, however the planet will furthermore be at its biggest and brightest of the year.
As Earth passes at once between Saturn and the solar, our planet will furthermore make its closest reach to Saturn of 2020. That closest reach will occur about 5 hours after opposition, per EarthSky.org. For the time being, Saturn will possible be 8.99 worthy devices (AU), or 8.99 cases the popular Earth-solar distance, a long way from our planet. At its farthest, Saturn’s distance from Earth is ready 11 AU.
Positioned in the constellation Sagittarius, Saturn will possible be at its highest at 1 a.m. local time, when it crosses the meridian, and it will possible be about 29 degrees above the southern horizon, per Heavens-Above.com calculations. The planet will possible be sparkling at magnitude 0.1, or about as intellectual as Rigel, the brightest huge identify in the constellation of Orion, the hunter. (Magnitude is a measure of brightness extinct by astronomers, with smaller numbers indicating brighter objects.)
Extra seen planets
On the day of the new moon, Venus and Mercury will each and every be “morning stars.” In Contemporary York City, Venus rises at 2: 52 a.m. local time, followed by Mercury at 4: 22 a.m. local time. That puts Venus in a truly easy jam to survey earlier than break of day, which is at 5: 42 a.m. local time. By 5 a.m. Venus will possible be an acceptable 23 degrees above the jap horizon in the constellation of Taurus, the bull, and intellectual adequate that it is a long way simple to discipline.
Mercury will possible be a more challenging target; at 5 a.m. it is fully 6 degrees above the horizon. Whilst you happen to may perchance well perchance luxuriate in a clear and flat glimpse eastwards, one methodology to trace Mercury is to survey for Venus, a intellectual white huge identify-love object, after which for Aldebaran, the brightest huge identify in Taurus, which is in a jam to be to the trusty and a diminutive upwards.
Aldebaran is recognizable since it will survey distinctly yellow-orange subsequent to Venus. Plot a line between Aldebaran and Venus to the left; you ought to quiet hit Mercury, which is in a jam to be sparkling at magnitude 0.7, about as intellectual Aldebaran.
Mars will furthermore be a predawn object on July 20, as it rises at 11: 45 p.m. and sets about six hours after break of day. Since it is in the constellation Cetus, which is rather faint, Mars will possible be evident to viewers as it will look to be the brightest “huge identify” and revel in a determined crimson hue.
Jupiter will furthermore be seen near to all evening; it looks to the trusty and above Saturn as the latter rises. Jupiter rises at 7: 53 p.m. local time in Contemporary York, and becomes seen after the solar sets. By spherical 10 p.m. local time the two will possible be seen as a pair to the left of the essential stars of Sagittarius.
Visible constellations
On the evening of the new moon, observers in mid-northern latitudes will look the accurate summer sky. High in the east, by 10 p.m. local time, the constellations of Lyra, Cygnus and Aquila will present the asterism the Summer time Triangle, consisting of Vega (Alpha Lyrae), Deneb (Alpha Cygni) and Altair (Alpha Aquilae). Vega, one among the brightest Northern Hemisphere stars, reaches end to the zenith — the level in the sky at once overhead — end to the stupid evening hours. The Milky Capacity, marking the perimeter of our galaxy, runs trusty thru the center of the Summer time Triangle and is seen from any discipline that lacks city lights, and one can look it stretch from Sagittarius in the south to Cassiopeia in the north.
Furthermore at about 10 p.m. local time one can look the constellations of Pegasus and Andromeda rising in the east. Andromeda turned into the legendary daughter of Cassiopeia, the “W”-formed constellation that will almost definitely be precisely on the quite a variety of aspect of Polaris, the North Wide identify, from the Wide Dipper (which between 10 p.m. and a pair of a.m. will possible be on the left aspect of Polaris, whereas Cassiopeia is on the trusty.)
According to Greek mythology, Andromeda turned into to be sacrificed to Cetus, the whale, but Perseus — whose constellation will possible be rising in the northeast by 10 p.m. and be fully seen by about stupid evening — rode in to the rescue on Pegasus, the winged horse. Cepheus, Cassiopeia’s husband, is lovely to the east of Cassiopeia, and each and every are seen in the sky collectively for lots of the year in the Northern Hemisphere.
On the evening of the new moon, since the sky will possible be freed from any interfering moonlight, by stupid evening the Andromeda constellation gives a bare-put a question to glimpse of the Andromeda galaxy, that will almost definitely be spotted a long way from city lights as a smudge of sunshine in Andromeda. Fetch it by finding the “Gigantic Square” of Pegasus and taking a in finding for the massive identify on the trusty nook; Andromeda is two trailing curves of stars with the Andromeda galaxy acting as a smudge above the uppermost line.
