Бурлящее оранжевое Солнце Orange Sun Simmering

Even a quiet Sun can be a busy place. And over the deep Solar Minimum of the past few years, our Sun has been unusually quiet. The above image, taken last week...

"Фалькон-9" выходит на орбиту Falcon 9 Launches to Orbit

A new rocket, the Falcon 9, was launched successfully from Cape Canaveral, Florida, USA, last week. The Falcon 9, standing about as high as a 15-floor building, was developed by the commercial SpaceX corporation as a step toward a relatively inexpensive space launch system.

Комета МакНота будет видна невооружённым глазом Comet McNaught Becoming Visible to the Unaided Eye

A new comet is brightening and is now expected to become visible to the unaided eye later this month. C/2009 R1 (McNaught) is already showing an impressive tail and is currently visible through binoculars.

Луноход отражает лазерные лучи Lunokhod: Reflections on a Moon Robot

It may look like some sort of cute alien robot, but it was created here on Earth, launched to the Moon in 1970, and now reflects laser light in a scientifically useful way. On November 17, 1970 the Soviet Luna 17 spacecraft landed the first roving remote-controlled robot on the Moon.

Вид Юпитера из стратосферы Jupiter from the Stratosphere

SOFIA, the Stratospheric Observatory for Infrared Astronomy, captured its "first light" images on May 26, from an altitude of 35,000 feet. While flying above most of planet Earth's infrared-absorbing water vapor, SOFIA's premier infrared views of the cosmos included this remarkable false-color image (right panel) of Jupiter.

Кривой след от метеора над Тенерифе A Twisted Meteor Trail Over Tenerife

Did this meteor take a twisting path? No one is sure. Considered opinions are solicited. Meteors, usually sand sized grains that originate in comets, will typically disintegrate as they enter the Earth's atmosphere. A fast moving meteor ionizes molecules in the Earth's atmosphere that subsequently glow when they reacquire electrons.

Широкоугольный инфракрасный телескоп: туманности Сердце и Душа WISE: Heart and Soul Nebulas in Infrared

Is the heart and soul of our Galaxy located in Cassiopeia? Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found. The Heart Nebula, officially dubbed IC 1805 and visible in the above right, has a shape in optical light reminiscent of a classical heart symbol.
