Под облаками Венеры Beneath Venus' Clouds
24.09.1996

If the thick clouds covering Venus were removed, how would the surface appear? Using an imaging radar technique, the Magellan spacecraft was able to lift the veil from the Face of Venus and produce this spectacular high resolution imageof the planet's surface.



Микроволновой диполь COBE: полет сквозь Вселенную COBE Dipole: Speeding Through the Universe
8.03.1997

Our Earth is not at rest. The Earth moves around the Sun. The Sun orbits the center of the Milky Way Galaxy. The Milky Way Galaxy orbits in the Local Group. The Local Group falls toward the Virgo Cluster of Galaxies.



Наш дом с высоты Home from Above
30.12.2008

There's no place like home. Peering out of the window of the International Space Station (ISS), astronaut Greg Chamitoff takes in the planet on which we were all born. About 350 kilometers up, the ISS is high enough so that the Earth's horizon appears clearly curved.



Свидетельства активности вулкана на Венере Evidence of an Active Volcano on Venus
14.01.2020

Are volcanoes still active on Venus? More volcanoes are known on Venus than Earth, but when Venusian volcanoes last erupted is not directly known. Evidence bolstering very recent volcanism on Venus has recently been uncovered, though, right here on Earth.



Вращающаяся Луна от LRO Rotating Moon from LRO
16.09.2013

No one, presently, sees the Moon rotate like this. That's because the Earth's moon is tidally locked to the Earth, showing us only one side. Given modern digital technology, however, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie has now been composed.



Молнии внизу Lightning Below
2.12.1995

In May of 1993, the Space Shuttle Columbia orbited the Earth carrying the Spacelab Deutsche 2 (SL-D



Марс приближается Mars Approach 2020
6.10.2020

Look to the east just after sunset tonight and you'll see a most impressive Mars. Tonight, Mars will appear its biggest and brightest of the year, as Earth passes closer to the red planet than it has in over two years -- and will be again for another two years.



Волокно отрывается от Солнца A Filament Leaps from the Sun
8.11.2021

Why, sometimes, does part of the Sun's atmosphere leap into space? The reason lies in changing magnetic fields that thread through the Sun's surface. Regions of strong surface magnetism, known as active regions, are usually marked by dark sunspots.



AR 3664: гигантская группа солнечных пятен APOD: 2024 May 11 Б AR 3664: Giant Sunspot Group
11.05.2024

Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big -- it's violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting the Earth, and others might follow.



Астероиды вдалеке Asteroids in the Distance
6.03.2011

Rocks from space hit Earth every day. The larger the rock, though, the less often Earth is struck. Many kilograms of space dust pitter to Earth daily. Larger bits appear initially as a bright meteor. Baseball-sized rocks and ice-balls streak through our atmosphere daily, most evaporating quickly to nothing.
