Пульсар Vela: нейтронная звезда-кольцо-выброс Vela Pulsar: Neutron Star-Ring-Jet

This stunning image from the orbiting Chandra X-ray Observatory is centered on the Vela pulsar -- the collapsed stellar core within the Vela supernova remnant some 800 light-years distant. The Vela pulsar is a neutron star. More massive than the Sun, it has the

Активные области, выбросы, рентгеновские вспышки Active Regions, CMEs, and X Class Flares

Space Weather forcasters are predicting major storm conditions over the next few days as the active Sun has produced at least three strong flares and a large coronal mass ejection (CME) since Tuesday, June 6th.

Взгляд на Ио с минимального расстояния Up Close to Jupiter's Moon Io

Above is the highest resolution photograph yet taken of the Solar System's strangest moon. The surface of Jupiter's moon Io is home to violent volcanoes that are so active they turn the entire moon inside out. The above photograph shows a region four kilometers across and resolves features only five meters across.

Непрерывное извержение на спутнике Юпитера ИО A Continuous Eruption on Jupiters Moon Io

A volcano on Jupiter's moon Io has been photographed recently during an ongoing eruption. Hot glowing lava is visible on the left on this representative-color image. A glowing landscape of plateaus and valleys covered in sulfur and silicate rock surrounds the active volcano.

В сердце Краба In the Heart of the Crab

The supernova explosion that formed the Crab Nebula was first seen on the year 1054. Last week, astronomers released a new image of the still-evolving center of the explosion. The above representative-color photograph...

MyCn18: Туманность Песочные Часы MyCn18: An Hourglass Nebula

The sands of time are running out for the central star of this hourglass-shaped planetary nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a Sun-like star's life occurs as its outer layers are ejected - its core becoming a cooling, fading White Dwarf.

Возвращение Комптона Compton Reentry

Nine years ago the massive Compton Gamma Ray Observatory, the second of NASA's space-based great observatories, was deployed in low earth orbit. Lofted above the protective atmosphere, Compton's instruments could explore the extreme high-energy Universe in gamma rays -- photons with 100,000 times or more the energy of visible light.

Секретная спираль IC 3328 The Secret Spiral Of IC3328

IC3328 is an otherwise unremarkable dwarf elliptical galaxy about 50 million light-years away in the Virgo cluster. But hidden within IC3328 is a subtle, beautifully symmetric spiral structure! A team of astronomers recently made this totally surprising discovery using detailed digital images from the European Southern Observatory's 8.2 meter Antu telescope.

Рентгеновский ветер от NGC 3783 X-Ray Wind From NGC 3783

A black hole is supposed to inexorably attract matter. But the intense radiation generated as material swirls and plunges into its high gravity field also heats up surrounding gas and drives it away.

Астронавт за работой Astronaut at Work

Did you ever have a day where everything got turned around and you just couldn't tell which way was up? Fortunately, this didn't happen to astronaut James S. Voss on May 21, who spent six hours preparing to fix and upgrade the International Space Station.
