APOD: 2025 March 31 Б Parker: The Solar System from Near the Sun
31.03.2025

If you watch long enough, a comet will appear. Before then, you will see our Solar System from inside the orbit of Mercury as recorded by NASA's Parker Solar Probe looping around the Sun.

Asteroid Gaspra s Best Face
27.10.2002

Asteroid 951 Gaspra is a huge rock tumbling in space. Gaspra became one of the best-studied spacecraft Galileo flew by. In the above photograph, subtle color variations have been exaggerated to highlight changes in reflectivity, surface structure and composition.

Asteroid Gaspra's Best Face
12.07.1998

Asteroid 951 Gaspra is a huge rock tumbling in space. Gaspra became one of the best-studied asteroids in 1991 when the spacecraft Galileo flew by. In the above photograph, subtle color variations have been exaggerated to highlight changes in reflectivity, surface structure and composition.

The Dark River to Antares
16.05.2020

A dark river seems to flow through this sky from the horizon toward colorful clouds near red giant star Antares. Murky looking, the dark river is a dusty nebula obscuring background starlight near the central Milky Way, although the dark dust nebula contains mostly hydrogen molecular gas.

Planets Ahoy
30.09.2008

Can you spot the Solar System's four rocky planets? In the above image taken on September 20, all of them were visible in a single glance, but some of them may be different than you think. Pictured above, the brightest and highest object in the sky is the planet Venus.

An Auroral Ring on Jupiter
9.06.1997

Do other planets have aurora? Terrestrial and spacecraft observations have found evidence for aurora on Venus, Mars, Jupiter, Saturn, Uranus, and Neptune. In the above false-color photograph, a good portion of an auroral ring was captured recently in optical light by the Galileo spacecraft in orbit around Jupiter.

Dusk of the Planets
29.04.2002

A great grouping of planets is now visible to the west just after sunset. Over the next two weeks, Mercury, Venus, Earth, Mars, Jupiter, and Saturn -- all the planets of the inner Solar System -- can be seen in a single knowing glance. The image on the left captured them all in one frame.

Moon and Planets by the Eiffel Tower
22.05.2002

The great evening grouping of planets is coming to an end. Before all the planets went their own separate directions, however, the Moon was kind enough to pose with some of them. The planets in the above picture, taken last week, are Venus and Jupiter.

18 Miles From Deimos
22.12.1996

Diminutive Deimos is the smallest of the two tiny Moons of Mars. Potato shaped and barely 6 miles wide this asteroid-like body was visited by the Viking 2 orbiter in 1977. This image was made when the spacecraft approached to within 18 miles of Deimos' surface.
