Эклиптозавр Рекс Eclipsosaurus Rex

We live in an era where total solar eclipses are possible because at times the apparent size of the Moon can just cover the disk of the Sun. But the Moon is slowly moving away from planet Earth. Its distance is measured to increase about 1.5 inches (3.8 centimeters) per year due to tidal friction.

Глобальное полярное сияние на Марсе Global Aurora at Mars

A strong solar event last month triggered intense global aurora at Mars. Before (left) and during (right) the solar storm, these projections show the sudden increase in ultraviolet emission from martian aurora, more than 25 times brighter than auroral emission previously detected by the orbiting MAVEN spacecraft.

Пластинчатый рельеф на Плутоне Pluto s Bladed Terrain

Imaged during the New Horizons spacecraft flyby in July 2015, Pluto's bladed terrain is captured in this close-up of the distant world. The bizarre texture belongs to fields of skyscraper-sized, jagged landforms made almost entirely of methane ice, found at extreme altitudes near Pluto's equator.

Туманность Душа в инфракрасном свете от обсерватории "Гершель" The Soul Nebula in Infrared from Herschel

Stars are forming in the Soul of the Queen of Aethopia. More specifically, a large star forming region called the Soul Nebula can be found in the direction of the constellation Cassiopeia, who Greek mythology credits as the vain wife of a King who long ago ruled lands surrounding the upper Nile river.

Ледяное кольцо вокруг близкой звезды Фомальгаут Ice Ring around Nearby Star Fomalhaut

Why is there a large ice ring around Fomalhaut? This interesting star -- easily visible in the night sky -- lies only about 25 light-years away and is known to be orbited by at least one planet, Dagon, as well as several inner dust disks.

Две кометы и звездное скопление Two Comets and a Star Cluster

Two unusual spots are on the move near the famous Pleiades star cluster. Shifting only a small amount per night, these spots are actually comets in our nearby Solar System that by chance wandered into the field of the light-years distant stars.

Самолет будущего: сверхзвуковая зеленая машина Concept Plane: Supersonic Green Machine

What will passenger airplanes be like in the future? To help brainstorm desirable and workable attributes, NASA sponsors design competitions. Shown here is an artist's depiction of a concept plane that was suggested in 2010.

Портрет NGC 281 Portrait of NGC 281

Look through the cosmic cloud cataloged as NGC 281 and you might miss the stars of open cluster IC 1590. Still, formed within the nebula that cluster's young, massive stars ultimately power the pervasive nebular glow.

Остаток сверхновой Корма А Puppis A Supernova Remnant

Driven by the explosion of a massive star, supernova remnant Puppis A is blasting into the surrounding interstellar medium about 7,000 light-years away. At that distance, this colorful telescopic field based on broadband and narrowband optical image data is about 60 light-years across.

Источник гравитационных волн GW170814 на карте неба LIGO Virgo GW170814 Skymap

From around planet Earth three gravitational wave detectors have now reported a joint detection of ripples in spacetime, the fourth announced detection of a binary black hole merger in the distant Universe. The event...
