NGC 3603: From Beginning To End
4.06.1999

From beginning to end, different stages of a star's life appear in this exciting Hubble Space Telescope picture of the environs of galactic emission nebula NGC 3603. For the beginning, eye-catching "pillars" of glowing hydrogen at the right signal newborn stars emerging from their dense, gaseous, nurseries.

The Kepler 90 Planetary System
28.04.2020

Do other stars have planetary systems like our own? Yes -- one such system is Kepler-90. Cataloged by the Kepler satellite that operated from Earth orbit between 2009 and 2018, eight planets were discovered, giving Kepler-90 the same number of known planets as our Solar System.

Worlds of a Distant Sun: 47 Ursae Majoris b
5.10.1997

In the last few years, observational astronomy has given humanity evidence of the existence of worlds beyond the solar system. Solar-type stars are now inferred to harbor planets of approximately Jupiter mass - some residing in temperature zones which could conceivably support liquid water and therefore life!

Searching For Solar Systems
15.11.1996

Observational astronomy has recently provided evidence of the existence of massive Jupiter-sized planets orbiting distant suns, protoplanetary disks of gas and dust surrounding newly formed stars, and planetary bodies orbiting exotic stellar corpses known as pulsars. Indeed, the formation of planets seems to be a broader and more varied phenomenon than previously imagined.

Gravel Ejected from Asteroid Bennu
16.09.2020

Why does asteroid Bennu eject gravel into space? No one is sure. The discovery, occurring during several episodes by NASA's visiting ORISIS-REx spacecraft, was unexpected. Leading ejection hypotheses include impacts by Sun-orbiting meteoroids, sudden thermal fractures of internal structures, and the sudden release of a water vapor jet.

NGC 4361: Galaxy Shaped Planetary Nebula
29.12.1995

Glowing in the red light emitted by hydrogen atoms, the planetary nebula NGC 4361 is pictured above. The nebula itself is formed by the outer layers of gas shrugged off by the central star visible in the image.

Water World
16.03.1997

Water (Dihydrogen Oxide, H2O) is a truly remarkable chemical compound, fundamental to life on Earth. Earth is the only planet in the Solar System where the surface temperature and pressure allow the three forms of water, solid (ice), liquid (ocean), and gas (water vapor condensing in clouds) to exist simultaneously on its surface.

Water (Dihydrogen Oxide, H2O) is a truly remarkable chemical compound, fundamental to life on Earth. Earth is the only planet in the Solar System where the present surface temperature and pressure allow the three forms of water, solid (ice), liquid (ocean), and gas (water vapor condensing in clouds) to exist simultaneously.

The Space Shuttle Docks with Mir
17.12.1995

Hundreds of kilometers above the Earth's surface, the United States Space Shuttle Atlantis docks with the Russian Space Station Mir. The photograph was taken by Nikolai Budarin from a Russian Soyuz spacecraft on July 4, 1995.
