Astronomy Picture Of the Day (APOD)

Кипящий центр галактики A Bubbling Galaxy Center

What's happening in the center of this galaxy? Close inspection of the center of NGC 4438, as visible in this recently released representative-color image by the Hubble Space Telescope, reveals an unusual bubble of hot gas, colored in red.

Сириус: ярчайшая звезда ночного неба Sirius: The Brightest Star in the Night

Sirius is the brightest star in the night sky. Sirius is visible on the far left of the above photograph, to the left of the constellation of Orion and Comet Hale-Bopp. Intrinsically, Sirius is over 20 times brighter than our Sun and over twice as massive.

M101: Вид в ультафиолете M101: An Ultraviolet View

This picture of giant spiral galaxy Messier 101 (M101) was taken by the Ultraviolet Imaging Telescope (UIT). UIT flew into orbit as part of the Astro 2 mission on-board the Space Shuttle Endeavour in March 1995.

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.
