Moon in Leo, June 7-9, 2019

The Moon passes beneath departing Leo because it waxes towards first quarter. (The blue 10° scale is concerning the width of your fist at arm’s size.)

Friday, June 7

• Simply after darkish search for Regulus higher left of the Moon, as proven right here. From there, hint out the remainder of Leo.

• Ceres, the biggest asteroid, dims barely from magnitude 7.1 to 7.three this week. Discover it about 9° north of Antares utilizing the article and finder chart within the Could Sky & Telescope, web page 48.

Saturday, June eight

• Now the Moon shines nearer above Regulus at dusk, as proven right here.

• The Massive Dipper hangs very excessive within the northwest after darkish. The center star of its bent deal with is Mizar, with tiny little Alcor proper subsequent to it. On which facet of Mizar must you search for Alcor? As all the time, on the facet towards Vega! Which is now the brightest star excessive within the east. In case your eyes aren’t fairly sharp sufficient, binoculars present Alcor simply.

Sunday, June 9

• First-quarter Moon (precise at 1:59 a.m. tonight EDT). The Moon shines within the hind ft of Leo. Look 10° above it (a couple of fist at arm’s size) for Denebola, the tip of Leo’s tail.

Virtually twice as far to the Moon’s decrease proper is Regulus, Leo’s forefoot.

Monday, June 10

• Jupiter is at opposition tonight, reverse the Solar as seen from Earth. It is that vibrant white level within the southeast after darkish. Jupiter is in southern Ophiuchus, to the left of orange Antares and the opposite, lesser stars of higher Scorpius.

And regardless of an ignorant information report that is circulating all around the world, you may see Jupiter’s moons with binoculars anytime Jupiter is up — not simply at opposition! Who produces this nonsense?

Tuesday, June 11

• Spica sparkles to the decrease left of the Moon this night. Greater than twice as far higher left of the Moon is brighter Arcturus.

Wednesday, June 12

• Now Spica is decrease proper of the moon, and Arcturus shines excessive above them.

Thursday, June 13

• With summer time solely eight days away, the Summer time Triangle stands excessive and proud within the east after darkish. Its prime star is vibrant Vega. Deneb is the brightest star to Vega’s decrease left (by 2 or three fists at arm’s size). Search for Altair a higher distance to Vega’s decrease proper.

Moon, Jupiter, Antares June 14-16, 2019

The waxing gibbous Moon now passes Antares and Jupiter, forming a pleasant triangle with them on the 15th.

Friday, June 14

• Look far beneath the Moon in late twilight and after darkish for Antares and Jupiter, as proven right here.

• The Massive Dipper now hangs straight down by its deal with as the celebs come out, excessive within the northwest.

Saturday, June 15

• Now the brilliant Moon types a not-quite-equilateral triangle with Jupiter to its decrease left and Antares to its decrease proper, as proven right here. Suppose picture alternative. The triangle is 10° from finish to finish, so use a reasonably lengthy lens. And even attempt zooming in with a cellphone digital camera braced rock-steady.


Need to turn out to be a greater astronomer? Be taught your manner across the constellations. They’re the important thing to finding every thing fainter and deeper to hunt with binoculars or a telescope.

That is an out of doors nature passion. For an easy-to-use constellation information masking the entire night sky, use the massive month-to-month map within the middle of every challenge of Sky & Telescope, the important information to astronomy.

Jumbo Pocket Sky Atlas cover

The Pocket Sky Atlas plots 30,796 stars to magnitude 7.6, and tons of of telescopic galaxies, star clusters, and nebulae amongst them. Proven above is the Jumbo Version for simpler studying within the night time. Pattern chart.

When you get a telescope, to place it to good use you will want an in depth, large-scale sky atlas (set of charts). The fundamental normal is the Pocket Sky Atlas (in both the unique or Jumbo Version), which reveals stars to magnitude 7.6.

Subsequent up is the bigger and deeper Sky Atlas, plotting stars to magnitude eight.5; almost thrice as many. The subsequent up, as soon as you realize your manner round, are the even bigger Interstellarum atlas (stars to magnitude 9.5) and Uranometria (stars to magnitude 9.75). And skim the way to use sky charts with a telescope.

You may additionally need a good deep-sky guidebook, comparable to Sue French’s Deep-Sky Wonders assortment (which incorporates its personal charts), Sky Atlas Companion by Sturdy and Sinnott, or the larger Night time Sky Observer’s Information by Kepple and Sanner.

Can a computerized telescope exchange charts? Not for rookies, I do not suppose, and never on mounts and tripods which might be lower than top-quality mechanically (that means heavy and costly). And as Terence Dickinson and Alan Dyer say of their Yard Astronomer’s Information, “A full appreciation of the universe can’t come with out growing the talents to search out issues within the sky and understanding how the sky works. This information comes solely by spending time beneath the celebs with star maps in hand.”

Jupiter with Great Red Spot on May 12, 2019

Jupiter’s Nice Pink Spot, imaged by Christopher Go on Could 12th earlier than it began to shed. South is up. “Seeing was excellent this morning,” Go writes. “The GRS is nicely resolved with many options seen inside it.” Darkish materials absolutely outlined the Pink Spot Hole and the spot itself and prolonged in two strains all the best way across the previous limb. However then. . .

Jupiter on May 22, 2019

. . .by Could 22nd the darkish rim made contact with the Pink Spot, and was apparently drawing off a few of it. Notice the spot’s unprecedented lumpy distortion on its left (previous; celestial west) facet. South is up.

Jupiter with flaking Red Spot, May 27, 2019

By the 27th, the flake on the left had indifferent and moved downstream (left), whereas a giant new one had shaped on the proper (following). And the Pink Spot itself seemed a bit smaller! Christopher Go picture.

Jupiter with Red Spot on May 29, 2019

Two days afterward Could 29th, the brand new blob on the Pink Spot’s following edge appeared to have shrunk and moved slightly southward (up). And slightly blob was embedded within the spot’s reverse facet. Christopher Go picture.

Jupiter with Red Spot, May 31, 2019

Two extra days (Could 31st) and the scene had modified once more. Writes Go, “The flake materials has now emerged on the SE [upper left] of the GRS as predicted.”

Jupiter and Red Spot, June 4, 2019

By June 4th the crimson flake materials was extra far-flung, and the spot itself seemed extra regular. Clyde Foster picture.

Mercury (in Gemini) glimmers low in night twilight. Search for it within the west-northwest about 45 to 60 minutes after sundown. This week it fades by nearly half, from magnitude –zero.6 to –zero.1. Do not confuse Mercury with twinklier Procyon some 25° to its left, or Capella about the identical distance to its proper.

Venus (magnitude –three.eight) could be very low within the daybreak. About 20 minutes earlier than dawn, scan for it with binoculars slightly above the east-northeast horizon.

Mars (a mere magnitude +1.eight, in Gemini) is higher left of much-brighter Mercury as night twilight fades away. Their separation closes quickly, from 8½° on June seventh to 2½° on the 14th. Pollux and Castor watch from above.

Mercury and Mars will seem closest collectively, a mere ½° aside or much less, on June 17th and 18th.

Jupiter (magnitude –2.6, in southern Ophiuchus) is at opposition on June 10th. This week it glares low within the southeast by late twilight. Antares, a lot fainter at magnitude, twinkles about 10° to its proper. Jupiter is highest within the south by round midnight or 1 a.m. daylight saving time, with orange Antares now to its decrease proper.

In a telescope Jupiter is 46 arcseconds huge. See Bob King’s Jupiter Is Excellent at Opposition. And massive modifications proceed in and round Jupiter’s Nice Pink Spot, as seen within the photos right here.

Saturn (magnitude +zero.three, in Sagittarius) rises across the finish of twilight. It is the regular, pale yellowish “star” about 30° east of Jupiter. Saturn’s opposition comes July ninth.

Uranus remains to be deep within the glow of daybreak.

Neptune (magnitude 7.9, in Aquarius) is within the east-southeast simply earlier than daybreak begins, far decrease proper of the Nice Sq. of Pegasus. Finder chart.


All descriptions that relate to your horizon — together with the phrases up, down, proper, and left — are written for the world’s mid-northern latitudes. Descriptions that additionally rely upon longitude (primarily Moon positions) are for North America.

Japanese Daylight Time (EDT) is Common Time (UT, UTC, GMT, or Z time) minus four hours.


Audio sky tour. Out beneath the night sky along with your earbuds in place, hearken to Kelly Beatty’s month-to-month podcast tour of the heavens above. It is free.


“This journey is made attainable by generations of searchers strictly adhering to a easy algorithm. Take a look at concepts by experiments and observations. Construct on these concepts that go the check. Reject those that fail. Observe the proof wherever it leads, and query every thing. Settle for these phrases, and the cosmos is yours.”
— Neil deGrasse Tyson, 2014
