 6月9日晚上,天空中两颗明亮的行星——金星与木星将要相合。 这是今年二者唯一的一次相合,是同时观测二者的最佳时机, 此后金星便逐渐远离木星。 相合时金星亮度约-4等,木星亮度约-1.9等。二者在天空中的角距仅约1.5度,且在日落1小时后仍有15度的高度,无论是哪方面讲, 都非常值得留心一看。 山東天文學會

  Twitter On the night of 8 January 2026, Russian forces launched an Oreshnik missile from Kapustin Yar test site that struck the city of Lviv, the first time Lviv Oblast was hit by a ballistic missile. The Ukrainian Air Force stated that the attack was combined with a wider drone and missile strike. Later, the Russian Ministry of Defense confirmed the Oreshnik strike on the Lviv State Aviation Repair Plant. On 24 May 2026, Russia fired a Oreshnik missile from Kapustin Yar during a large overnight attack on Ukraine, combined with 600 drones and 90 other missiles. According to experts, many components were manufactured no later than 2016–2017, including Russian and Belarusian elements (from the Integral plant in Belarus). One of the units even bears a clear 2017 production date. Despite Russian propaganda presenting the “Oreshnik” as a cutting-edge weapon, it is largely assembled from older parts. Foreign components from China, the USA, Japan, Germany, and Switzerland were also disc...

  faster variants powered by jet engines known as the Geran-3, Geran-4, and Geran-5. The Geran-3 made its combat debut last year. On Monday, Ukraine's military intelligence agency, the GUR, said Russia had started using the newer Geran-4 in attacks this month "as a countermeasure against the effectiveness of our interceptor" drones. Geran-4 is powered by a Chinese-made turbojet engine and can fly as fast as 500 km/h (roughly 310 mph) and cruise at an altitude of 5,000 meters (1,640 feet), the GUR said. The drone can carry a highly explosive warhead over a distance of 450 kilometers (280 miles). According to the document, the Geran-5 is equipped with a 200 kilogram-thrust turbojet engine, which GUR identifies as being of Chinese origin. The system is reportedly capable of achieving a maximum range of 950 kilometres and a top speed of 600 km/h while retaining the Geran-2’s 90 kg payload. Another jet-powered variant, the Geran-4, reportedly is also under development. Compare...
