Multiple Whirlpools in a Sodium Gas Cloud

This image depicts the formation of multiple whirlpools in a sodium gas cloud. Scientists who cooled the cloud and made it spin created the whirlpools in a Massachusetts Institute of Technology laboratory, as part of NASA-funded research.

Stardust on approach

Artist’s rendering of the Stardust spacecraft. The spacecraft was launched on February 7, 1999, from Cape Canaveral Air Station, Florida, aboard a Delta II rocket. The primary goal of Stardust is to collect dust and carbon-based samples during its closest encounter with Comet Wild 2 — pronounced “Vilt 2” after the name of its Swiss discoverer.

Hypersonic Flight Vehicle X-43B

An artist’s rendering of the air-breathing, hypersonic X-43B, the third and largest of NASA’s Hyper-X series flight demonstrators, which could fly later this decade. Revolutionizing the way we gain access to space is NASA’s primary goal for the Hypersonic Investment Area, managed for NASA by the Advanced Space Transportation Program at the Marshall Space Flight Center in Huntsville, Alabama.

Dusty Beginnings of a Star

This artist’s rendering gives us a glimpse into a cosmic nursery as a star is born from the dark, swirling dust and gas of this cloud. Stars form when dark dust from the cloud begins to clump together under the influence of its own gravity. The infalling material forms a disk as it spirals inward, which feeds material onto the forming star at its center. Jets of material that shoot from the inner disk and protostar herald its birth.

Mars exploration

Planners feel the microscopic formations in Mars meteorite ALH84001, found in Antarctica, and the highly diverse samples of rocks believed to have been strewn about by ancient rivers seen at the Mars Pathfinder landing site, provide a strong motive for sending human exobiologists and geologists to the Red Planet. This artist’s rendering depicts two such scientists.

Solar System exploration

On the way to the Jovian system, a nuclear thermal transfer vehicle refuels in a Mars-orbit near Martian moon Phobos, in this artist’s rendering. This steady-state system could provide a reliable foundation for the exploration and eventual colonization of the Solar System. This image produced for NASA by Pat Rawlings, (SAIC).

Sunset on Enceladus

In this artist’s rendering, a distant sun forms a halo (refracted sunlight by ice crystals) amid streamers of pure water ice particles, which spew into space from cracks in the south polar surface of Saturn’s tiny moon Enceladus.

Eclipsing Pulsar Promises Clues to Crushed Matter

Astronomers using NASA’s Rossi X-ray Timing Explorer (RXTE) have found the first fast X-ray pulsar to be eclipsed by its companion star. Further studies of this unique stellar system will shed light on some of the most compressed matter in the universe and test a key prediction of Einstein’s relativity theory.

Lunar Meteor Strike

This artist’s rendering of a small but powerful meteor strike on the surface of the moon demonstrates a key concern for future lunar explorers — mitigating potential risks from impact “ejecta,” or the spray of debris that follows an impact, unimpeded by gravity or atmosphere. NASA astronomers are studying lunar impacts to help safeguard future missions to Earth’s nearest celestial neighbor. (NASA/MSFC)

Alien World

This artist’s rendering shows a gas-giant exoplanet transiting across the face of its star. Infrared analysis by NASA’s Spitzer Space Telescope of this type of system provided the breakthrough.

The IC 10 X-1 black hole

In this artist’s portrayal of the IC 10 X-1 system, the black hole lies at the upper left and its companion star is on the right. The two objects orbit around a center of gravity once every 34.4 hours. The stellar companion is a type known as a Wolf-Rayet star. Such stars are highly evolved and destined to explode as supernovae. The black hole companion is shedding its outer envelope in a powerful wind, and some of this gas is captured by the black hole’s powerful gravity.
