This week is all about the absence—and then the dramatic and delicate reappearance—of the Moon. Its absence from the night sky is a boon for stargazing, making it much easier to see deep sky sights such as star clusters, galaxies and nebula (but also more stars).
It also means that for most of this week we can see—from a dark sky site—the Milky Way arcing across the sky and streaming down to the southern horizon right after dark. Look for Jupiter and Saturn in the south; the Milky Way is right there!

The reason we're shooting laser beams between Earth and the moon - CNN
(CNN) For the first time ever, scientists received a signal after sending laser beams from Earth to a reflector on NASA's Lunar Reconnaissance Orbiter around the moon.
E-Ink Moon Phase Viewer Keeps Interest From Waning | Hackaday
[Jacob]’s moon phase viewer runs on an ItsyBitsy M4 Express, which holds data pulled from NASA ahead of time to save battery. Every morning, the board dishes out the daily info on a schedule kept by a real-time clock module.
We particularly like the minimalist case design, especially the little shelf that holds the lithium-ion cell. This is just the beginning, and [Jacob] plans to add more detail for anyone who wants one for themselves.
If you want something more Moon-shaped, here’s a printed version that gets brighter in time with the real thing . Or you could just make a giant light-up full moon like Hackaday super alumnus [Caleb Kraft].
See Venus and the moon cozy up with winter constellations early Saturday | Space
It's hard to believe that in the midst of midsummer I'm writing about winter stars and constellations. But there's a good reason.
If you have ever been outside on a winter's night you have no doubt enjoyed the sight of the year's brightest stars and constellations . But you also have likely cut short your observing session for a good reason: the cold temperatures. Many stargazers have been adversely affected by frosty, sometimes bone-chilling conditions. Such a pity, since there are so many glorious sights that the winter sky offers to us.

August 2020's New Moon In Leo - How It Affects Your Zodiac Sign
Summer is slooowly wrapping up, and that comes with a big feeling that everything is about to change. Meanwhile, you just want to be comfortable and revel in the fact that there’s still beachy weather to enjoy.
Quick astronomy recap before getting into it: As you probably know, the moon has different phases. A new moon happens when the earth lines up with the sun, making the moon look all but invisible from Earth. Typically, there are 12 new moons a year, with each new moon tied to a different astrological sign. But some years—like this one (of course)—have 13 new moons.
Entire cities could fit inside Moon's monstrous lava tubes - Tech Explorist
Lava tubes can be found on planet Earth and the subsurface of the Moon and Mars. Evidence of lava tubes was often inferred by observing linear cavities and sinuous collapse chains where the galleries cracked.
These collapse chains represent ideal gateways or windows for subsurface exploration. The morphological surface expression of lava tubes on Mars and the Moon is similar to their terrestrial counterpart.
A new study by the Universities of Bologna and Padua and its coordinators at Francesco Sauro and Riccardo Pozzobon offers an estimate of the (greater) size of their lunar and Martian counterparts.
Powering the Galilean Satellites with Moon-Moon Tides - Astrobiology
Resonant ocean thicknesses at different forcing frequencies. a) Location of Europa's first three largest resonant rotational-gravity modes as a function of forcing frequency and ocean thickness, for both zonal (m = 0) and sectoral (m = 2) degree-2 modes. The sole resonant mode in the non-rotating limit is shown in red. b) Frequency decomposition of the sectoral degree-2 tidal potential at Europa due to Jupiter, Io, and Ganymede.
There is compelling evidence for subsurface water oceans among the three outer Galilean satellites, and evidence for an internal magma ocean in the innermost moon, Io. Tidal forces from Jupiter periodically deform these bodies, causing heating and deformation that, if measured, can probe their interior structures.
August 2020: The Next Full Moon is the Sturgeon Moon – NASA Solar System Exploration
The Next Full Moon is the Sturgeon Moon, the Green Corn Moon, the Raksha Bandhan Moon, Nikini Poya, and the end of the Esala Perahera festival.
The next full Moon will be midday on Monday, August 3, 2020, appearing "opposite" the Sun (in Earth-based longitude) at 11:59 AM EDT. The Moon will appear full for about three days centered around this time, from late Saturday night through early Wednesday morning.
The Maine Farmer's Almanac first published "Indian" names for the full Moons in the 1930's, and over time these names have become widely known and used. According to this almanac, as the full Moon in August and the second full Moon of Summer, the Algonquin tribes in what is now the northeastern USA called this the Sturgeon Moon after the large fish that were more easily caught this time of year in the Great Lakes and other major bodies of water.
