(2228) Союз-Аполлон


Именно так 4 апреля 1965 года действовала четверка МиГ-17Ф против восьми Ф-105D неподалеку от Тхань Хоа. При этом капитан Трап Хань и его ведомый сбили два Ф-105D (пилоты: капитан Джеймс Мэгнессон, майор Фрэнк Бэннэт). Это были первые сбитые из 320 американских самолетов, уничтоженных северовьетнамскими ВВС в воздушных боях.


В июле 1965 года впервые был применен новый вид оружия, внесший существенные коррективы в ход воздушной войны, — советский зенитно-ракетный комплекс С-75. 24 июля 1965 года дивизион С-75 ракетным залпом сбил в 30–40 км к юго-востоку от Ханоя три истребителя-бомбардировщика Ф-4С. Самолеты шли с бомбовой нагрузкой в плотном строю на высоте 2000 метров.

Неприятным сюрпризом для американцев было применение во Вьетнаме истребителя МиГ-21. Первый бой с его участием состоялся 23 апреля 1966 года. После этого боя американцы пытались применять усиленное прикрытие ударных групп истребителями «Фантом II», возможности ведения воздушного боя которых примерно соответствовали МиГ-21. Наибольшее распространение во Вьетнаме получил МиГ-21ПФ-В (специальный вариант МиГ-21ПФ для влажных климатических условий Вьетнама с антикоррозионными покрытиями агрегатов).

31 марта 1968 года американские бомбардировки Вьетнама севернее 19-й параллели были прекращены, в Париже начались мирные переговоры. Закончилась воздушная война, стоившая Америке 3495 потерянных современных самолетов.

30 апреля 1975 года над Дворцом Независимости в Сайгоне было поднято Красное знамя — война закончилась.

Вьетнам потерял около 2 млн мирных жителей в обеих частях страны (по другим данным, около 3). Общие потери вьетнамских военнослужащих — около 1,5 млн человек.

США понесли тяжелые потери во вьетнамской войне — 58 тысяч военнослужащих убитыми (боевые потери — 47 тысяч, небоевые — 11 тысяч; пропавшими без вести считаются более 1700 человек); 303 тысячи ранеными (госпитализировано — 153 тысячи, легкие ранения — 150 тысяч.)

В ходе войны зенитными ракетами только комплексов С-75 были сбиты, по разным оценкам, от 1370 до 2500 самолетов противника. (Всего было сбито около 5000 самолетов США.) Американцы не признают этих цифр, их авторы пишут о существенно меньших потерях. Но и они пишут о 2257 самолетах, потерянных в операциях. Среди них названы 26 Б-52, 445 Ф-4 «Фантом», 397 А-105 «Тандерчиф», 243 Ф-100 «СуперСейбр».

Обеими сторонами было заявлено и о появлении в этой войне асов — 10 вьетнамцев и три американца, один из последних не летчик, а оператор наведения «Фантома», то есть асом, по сути, не является.

На расстоянии примерно 2500 (1700 - 2700) световых лет от Земли, в самом большом (1302.844 кв°) из существующих, весеннем созвездии Водяной змеи - Гидры (Hydra) расположена необычная, потому что имеет практически идеально круглую форму, что является редкостью для объектов подобного рода, планетарная туманность Abell 33 ..

HD 83535 (HIP 47369) - яркая белая звезда главной последовательности, спектрального типа A0 / A1 V и визуальной яркостью 7.21m. (± 0.01) случайно оказавшаяся на кромке туманности Abell 33 всего лишь проекция и никак не связана с ней, тем более что и расстояние до неё от Земли примерно в два раза короче ..

Вместе, слабая (~13.4m.) планетарная туманность и яркая (7.21m.) белая звезда, на изображении полученном с помощью Очень большого телескопа (Very Large Telescope / VLT) расположенного на южной европейской (ESO) обсерватории в Чили (Chile) выглядят как кольцо с сияющим камнем (sparkling diamond ring) ..

Alpha Cam blue-white class O bright super giant runaway star associated cluster NGC 1502 . It appears faint because it is dimmed by nearly a full magnitude by intervening interstellar dust and its true luminosity might be as much as 530,000 Suns!

NGC 1502 is a magnitude 6.0 open cluster about 3,000 light years from Earth. It has about 45 bright members, and features a double star of magnitude 7.0 at its center. NGC 1502 is also associated with Kemble's Cascade, an small chain of stars 2.5° long that is parallel to the Milky Way and is pointed towards Cassiopeia.

NGC 1502 (RA: 4:07.7, Dec: +62:20). It is located 3,000 light years away in the constellation Camelopardalis on the outer portion of our Local Spiral Arm while we are farther back on the trailing end of the arm. Or, it may be that NGC 1502 lies between our spiral arm and the next one out, the Perseus Spiral Arm.

NGC 1501 Oyster Nebula (Camel's Eye Nebula) planetary nebula bright, circle of luminosity just one arc minute across. At powers in excess of 200x its disc reveals a slightly darker centre much like the Ring Nebula, only much more subdued. The 14th-magnitude central star can be difficult to spot. Clearly visible at 250x in my 10-inch F/5 reflector on good nights, it can suddenly disappear when the seeing deteriorates.
NGC 1501 is a bright planetary nebula with a blue color visible from a dark sky, glowing at magnitude 11.5, located 4,900 light-years distant. Though it’s not naked eye visible, it’s easy to find in a moderate-sized (6-12 inch) telescope. It will remind experienced observers of the Eskimo nebula in Gemini. If your sky conditions allow, view this nebula at high power – I used a 9mm eyepiece on my 12.5 inch f/5.75 reflector for a magnification of 202X. At this power I was able to see the faint blue color, dark and light markings, and see that it was wider in the middle. 8-10 inch telescopes will show this detail at high power from a dark sky.

For larger telescopes and an observing challenge, try planetary nebula NGC 1501. Discovered in 1787 by Sir William Herschel and located about 4,890 light years away, this irregular disc has a great 14th magnitude central star hidden inside the dimpled structure which gives rise to its popular moniker – the “Oyster Nebula”.

IC 342 (IC stands for Index Catalogue, one of two supplements to the NGC. The first was published in 1895 and contained 1,520 objects, while the second was published in 1908 and contained 3,866 objects, for a total of 5,386 IC objects). IC 342 is a spiral galaxy seen face-on. The nucleus is bright and the spiral arms are visible in a dark sky through moderate sized telescopes such as my 12.5 inch reflector. The magnitude is an easy 9.1 — easy through a telescope, not naked-eye visible. It is 6.5 million light years away. On the SW side of the galaxy, a string of foreground Milky Way stars – 6 stars in a straight line – are easy to see. IC 342 is one of the brightest two galaxies in the IC 342/Maffei Group of galaxies, one of the galaxy groups that is closest to our Local Group. In 1935, Harlow Shapley declared that this galaxy was the third largest spiral galaxy by angular size then known, smaller only than the Andromeda Galaxy (M31) and the Triangulum Galaxy (M33), being wider that the full moon. (Modern estimates are more conservative, giving the apparent size as one-half to two-thirds the diameter of the full moon). It is almost hidden from view behind the veil of stars, gas and dust clouds in the plane of our Milky Way galaxy!

Хотя, конечно, светло сейчас. Даже "Сову" - болт найдешь:(. И вот М56 в Лире - совсем невзрачным кажется.

First, the Voyager 1 spacecraft, launched in 1977, is currently 128 astronomical units from the Sun (a little over 3 times the distance from the Sun to Pluto). It is the farthest man-made object in the universe. It is traveling in the general direction of this cluster at a million miles per day in the dark, cold abyss of interstellar space, where it is barely above absolute zero, with our Sun a bright point of light some 12 billion miles away, and the Earth a distant memory. As you look at it, just image that somewhere, between Earth and these stars is a tiny, imperceptible vestige of our planet.

Second, at a distance of 3,000 light years, the light you are seeing from these stars left on their cosmic journey at the time of King David's reign in Israel, a thousand years before the birth of his descendant, Jesus of Nazareth.

Хотя, конечно, светло сейчас.
Вот-вот, еще поправочку на широту сделайте...
Но и фонари слепят - дай боже. Поэтому в SW909 видел практически на пределе...
Впрочем, как стемнеет еще попробую, возможно это уже засветка неба так влияла.

И вот М56 в Лире - совсем невзрачным кажется, точно также как и М44 при большом увеличении, когда оно не входит целиком в поле зрения телескопа.
Не, Вы меня не путайте, "Ясли" (М44) - они рассеянное скопление, а М56 - таки вполне шаровик! Само собой, что такую яркую рассеянку на 120х я смотреть ну никак не буду, разве что после пива, да и то вряд-ли!

Но твари, скользящие в ней,
Хороши к жигулевскому пиву…
