Сегодня не день, а просто праздник какой-то.
Смеяться по ссылке.

Нет, это оказывается не всё.

Пошла читать.
Даже жаль, что яйца хотя и стоят, но не только в equinox.

Решила сходить поздно вечером на почту, бросить нетфликсовский конверт в почтовый ящик. Прошла три мили (моцион), и сфотографировала красивую луну и Юпитер. Обратите внимание, что у Луны есть нос. Под катом фотки и немного про Юпитер.

Morning Sky

 Venus at midmonth at -4.1 magnitude, diameter 17.6", illumination 64.73%. On the 12th a waning crescent passes about 4° from Venus. Venus is located in the constellation Cancer the Crab. Venus rises in the east around 3:15 AM. Best seen just before sunrise. On September 12th look for Venus only 02°38'13" away from M-44 the Beehive open cluster. The crescent moon is only 04°26'10" from Venus.

The planet is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows.

Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, for which reason it has been referred to by ancient cultures as the Morning Star or Evening Star.

It is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. Venus has the densest atmosphere of the four terrestrial planets, consisting mostly of carbon dioxide.

Spirit, MER-A (Mars Exploration Rover – A), is a robotic rover on Mars, active from 2004 to 2010. It was one of two rovers of NASA's ongoing Mars Exploration Rover Mission. It landed successfully on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, Opportunity (MER-B), landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition. The rover became stuck in late 2009, and its last communication with Earth was sent on March 22, 2010. 

The rover completed its planned 90-sol mission. Aided by cleaning events that resulted in higher power from its solar panels, Spirit went on to function effectively over twenty times longer than NASA planners expected following mission completion. Spirit also logged 7.73 km (4.8 mi) of driving instead of the planned 600 m (0.4 mi),[3] allowing more extensive geological analysis of Martian rocks and planetary surface features. Initial scientific results from the first phase of the mission (the 90-sol prime mission) were published in a special issue of the journal Science.[4]

Blue Moon

A blue moon is the appearance of the third full moon in a season with four full moons. The term has also mistakenly been used to refer to the second full moon in a month. Most years have twelve full moons that occur approximately monthly. In addition to those twelve full lunar cycles, each solar calendar year contains roughly eleven days more than the lunar year of 12 lunations. The extra days accumulate, so every two or three years (7 times in the 19-year Metonic cycle), there is an extra full moon. Lunisolar calendars have rules about when to insert such an intercalary or embolismic ("leap") month, and what name it is given; e.g. in the Hebrew calendar the month Adar is duplicated. The term "blue moon" comes from folklore. Different traditions and conventions place the extra "blue" full moon at different times in the year. In the Hindu calendar, this extra month is called 'Adhik(extra) masa (month)'. It is also known as purushottam maas, so as to give it a devotional name.

On Friday night a rare blue moon will rise in the sky in an astronomical event that occurs only once every three years or so. If you're hoping to see the blue moon but the sky above you is cloudy, don't fret. The web-based Slooh Space Camera will broadcast the event live beginning at 6 p.m. EDT. (The website's even got a countdown clock to its blue moon coverage.

Friday evening's blue moon will allow fans of the late Neil Armstrong to marvel at man's incredible feat. Armstrong was the first man to set foot on the lunar surface back in 1969. This photo was taken early Friday morning as the moon technically turned full. Photo: Travis Burke

As the Perseid meteor shower peaks on the mornings of August 11-13, the moon and brightest planets will be dazzling before dawn.
