Magnetic monopoles are hypothetical particles with a single magnetic charge — north without south. Predicted by grand unified theories, they may be incredibly massive and could bind together into “magmatter,” an ultra-dense material stronger than anything known in nature.

Thanks to a fleet of advanced spacecraft surveying the surface, a new portrait of Mars is emerging. The Red Planet teeters on the border between a living and a dead world. Discover three prospects for human existence on Martian terrain.

Jupiter, Saturn, Uranus, and Neptune represent planets with exotic atmospheres and liquid interiors. Looking beyond these gaseous worlds we find Pluto, a planet in deep freeze, which may be preserving the history of our solar system.

Сегодня ночью прощаемся с грузовиком — после полугодового пребывания на МКС «Прогресс МС-32» отчалит от модуля «Звезда» Международной космической станции

▶️ Ожидаем включение двигателя на торможение в 04:11 мск.

В результате корабль войдёт в плотные слои атмосферы и разрушится.

По данным Центра управления полётами ЦНИИмаш, несгоревшие элементы конструкции корабля упадут в несудоходном районе южной части Тихого океана.

Корабль был запущен с Байконура ракетой «Союз-2.1а» 11 сентября и спустя двое суток прибыл на МКС.
