June skygazing: A strawberry moon, the summer solstice… and Asteroid Day!

While the comparatively brief nights of summer imply much less darkish skies for stargazing, this month ought to nonetheless present loads to occupy these of us given to trying to the sky. June will function a number of alternatives to see Mars and the moon in shut proximity to Regulus, the iconic blue star(s) that shine from the coronary heart of Leo, together with two weeks’ price of fantastic alternatives for observing Mercury. And do you know that June 30 is International Asteroid Day?

June 1– Crescent Moon Visible Between Mars and Regulus

The first night of June will discover the crescent moon sitting squarely between Mars and Regulus, the brightest member of the constellation Leo. Interesting truth: whereas it seems like a single object, the blue “star” we see as Regulus isn’t only one star. It’s really 4. The largest and brightest, Regulus A, is considerably hotter than our solar and means, means brighter than our solar, and is believed to be in a binary orbit with a a lot smaller object. This object is more than likely a white dwarf, but it surely has by no means been noticed immediately. The different two stars–Regulus B and C–are additionally dwarf stars, and are additionally locked in a binary orbit.

Anyway, hold Regulus in thoughts, as a result of we’ll be returning to it later in the month.

June 11– Full Strawberry Moon

This month, the moon will attain peak illumination in the early hours of June 11. If you’re on EDT, the full moon might be at 3:44 a.m. This month’s moon is named the Strawberry Moon, and of all the beautiful names for the full moon, June’s may simply be the prettiest. The title refers to the berries that ripen as the summer solstice approaches, not the coloration of the moon itself, which is able to stay resolutely silver. Several Native American languages use this time period, together with Ojibwe, Oneida, and the Mahican dialect of the Stockbridge-Munsee band of Wisconsin. Other languages have equally poetic names: in the Catawba language it’s the “River Moon” and in Cherokee it’s “They Are Arriving/Plants in Garden are Sprouting Month”, whereas in Seneca and Tunica it’s merely the “Summer Moon.”

Mid-June– Mercury Shows Off

Our photo voltaic system’s innermost planet may be tough to look at—it’s small, dim, and loads of the time, it merely will get misplaced in the glare of the solar. However, this month marks considered one of the common intervals when Mercury seems far sufficient faraway from the solar to be seen to the bare eye.

Throughout June, Mercury will method its most japanese elongation,the level at which it seems furthest east of the solar. Unfortunately, its magnitude—i.e. its obvious brightness—will decline over the course of the month, and by the time it hits most elongation in early July, it’ll be dim sufficient that you just may battle to identify it with out the help of a telescope or some binoculars.

This signifies that mid-June will supply the finest steadiness of elongation and magnitude. As per the ever indispensable Farmer’s Almanac, Mercury ought to be seen between 9:00 p.m. and 9:15 p.m. native time, low in the sky to the west-northwest. On June 26, it’ll peek out from barely under and to the left of the crescent moon.

June 16-18– The Red Planet Meets the Blue Heart of Leo

So, one other factor about Regulus: it sits near the airplane of the photo voltaic system, which signifies that it’s typically seen in shut proximity to the moon and the planets.

This month brings one such event: for the nights of June 16, 17, and 18, Regulus will seem proper subsequent to Mars. The proximity of the Red Planet and the blazing blue coronary heart of the constellation Leo ought to make for a fairly spectacular celestial juxtaposition.

June 20– The Summer Solstice

In the Northern Hemisphere, June 20 is the day on which the solar is highest in the sky, aka the summer solstice! This is the day on which the North Pole is tilted most immediately towards the solar, bringing 24-hour daylight to the Arctic Circle and the longest day of the yr to the remainder of the Northern Hemisphere. Summer is right here, y’all!

June 30– International Asteroid Day

June 30 marks the anniversary of the Tunguska Event, a frankly terrifying asteroid strike that continues to be the largest asteroid impression occasion in recorded historical past. On June 30, 1908, an asteroid estimated to be  about 160 to 200 ft broad exploded a number of miles above the floor of a distant space of Siberia. The pressure of the detonation is estimated to be similar to  between 3 and 50 megatons of TNT, and registered on seismographs round the world. For comparability, the atomic bombs dropped on Hiroshima and Nagasaki had yields of 0.015 and 0.021 megatons, respectively.) The resultant shockwave flattened an estimated 80 million timber over an space of 830 sq. miles and broke home windows a whole lot of miles away.

In 2014, a bunch of scientists proposed that June 30 be designated International Asteroid Day. The UN adopted the thought two years later. The day acknowledges the probably calamitous impact of asteroid impacts—what might need occurred had the Tunguska asteroid hit a metropolis as a substitute of a barren a part of Siberia doesn’t actually bear serious about—and to boost consciousness about the significance of asteroid-tracking endeavors.

Anyway, hopefully June’s stargazing endeavors received’t reveal any terrifying asteroids hurtling towards us. Whatever you’re setting your sights on, although, you’ll get the finest expertise in case you get away from any sources of sunshine air pollution—and you be sure to take a look at our stargazing ideas earlier than you head off into the darkness.

Until subsequent month!
