2018 July 12
Explanation: Only 11 million light-years away, Centaurus A is the closest active galaxy to planet Earth. Spanning over 60,000 light-years, the peculiar elliptical galaxy also known as NGC 5128, is featured in this sharp telescopic view. Centaurus A is apparently the result of a collision of two otherwise normal galaxies resulting in a fantastic jumble of star clusters and imposing dark dust lanes. Near the galaxy’s center, left over cosmic debris is steadily being consumed by a central black hole with a billion times the mass of the Sun. As in other active galaxies, that process likely generates the radio, X-ray, and gamma-ray energy radiated by Centaurus A
The closest new moon of 2018 – a supermoon – comes on July 13. You won’t see it, but Earth’s oceans will feel it. Then, 2 weeks later, we have the year’s farthest full moon.
2018 will have three new moon supermoons in a row, which are defined as new or full moons at or near their closest to Earth for that particular month. 2018’s new supermoons fall on June 13, July 13 and August 11. Thus this next new moon on July 13 is a supermoon; in fact, it’s the closest and largest of the three.
New moon falls precisely on July 13, 2018, at 2:48 UTC; that is July 12 at 10:48 p.m. EDT., 9:48 p.m. CDT and so on.
You don’t typically see a new moon, not even a new supermoon, but Earth’s oceans will feel it. This extra-close new moon will combine with the gravitational pull of the sun to give rise to wide-ranging spring tides – tides that are extra high and extra low – in the few days following July 13.
Plus, a few people in Earth’s Southern Hemisphere will glimpse this July 13 new moon. At least, they’ll see the new moon silhouette, or part of it, during a partial solar eclipse on July 13. A month from now, people at high latitudes in the Northern Hemisphere will be able to view the new supermoon during a second partial solar eclipse, on August 11.
Two weeks from July 13 – on Friday, July 27, 2018 – we’ll have the smallest full moon of the year. The year’s smallest full moon is sometimes called a micro-moon or mini-moon. It’s the opposite of a supermoon. A micro-moon always happens within a fortnight of the year’s closest new moon.
Moreover, this upcoming full moon on July 27 will stage this century’s longest total lunar eclipse that’ll be visible from most of the world’s Eastern Hemisphere – but not from North America.
The July 13 new moon comes especially close to Earth because it’s the year’s closest coincidence of a new moon with a lunar perigee.
New moon: July 13, 2018, at 2:48 UTC
Lunar perigee: July 13, 2018, at 8:28 UTC
But this is not the closest supermoon. Remember, supermoons can be new or full moons. At a distance of 222,097 miles (357,431 km), the July 13 perigee is only the 2nd-closest of this year’s 14 lunar perigees. The year’s closest perigee of 221,559 miles (356,565 km) accompanied the full moon supermoon on the night of January 1-2, 2018. Thus that full moon was 2018’s closest supermoon.
Now here’s an older term for the close alignment of the July 13 new moon with lunar perigee: some will call it a perigean new moon.
One fortnight after the perigean new moon, it’ll be a apogean full moon on July 27, 2018, that features the year’s closest coincidence of full moon with lunar apogee. At a distance of 252,415 miles (406,223 km), this will be the 2nd-farthest of this year’s 13 apogees. The apogean full moon on July 27 will be about 30,000 miles or 50,000 km farther away than the perigean full moon of July 13.
Full moon: July 27, 2018, at 20:20 UTC
Lunar apogee: July 27, 2018, at 5:44 UTC
The year’s farthest apogee – 252,565 miles (406,464 km) – took place on January 15, 2018, or one fortnight after the year’s closest perigee in early January 2018.
Don’t you just love the orderliness of the heavens?
Bottom line: The closest new supermoon of 2018 comes on July 13.
