Cassini Spacecraft Shows Saturn's Northern Hemisphere

New images from NASA’s Cassini Spacecraft from its new orbit of Saturn. NASA’s Cassini spacecraft has sent to Earth its first views of Saturn’s atmosphere since beginning the latest phase of its mission. The new images show scenes from high above Saturn’s northern hemisphere, including the planet’s intriguing hexagon-shaped jet stream. Cassini began its new […]

Hubble Telescope Views NGC 4388

This newly released Hubbleimage show NGC 4388, which is located 60 million light-years away. The constellation of Virgo (The Virgin) is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of over 1300 galaxies called the Virgo Cluster. One particular member of this cosmic community, NGC 4388, is […]

Cassini Sees Tiny Mimas Huge Rings

In this new image from the Cassini Spacecraft, Saturn’s icy moon Mimas is dwarfed by the planet’s enormous rings. Because Mimas (near lower left) appears tiny by comparison, it might seem that the rings would be far more massive, but this is not the case. Scientists think the rings are no more than a few […]

Hubble Views Irregular Galaxy IC 3583

This newly released Hubble image shows a delicate blue group of stars — actually an irregular galaxy named IC 3583 — located 30 million light-years away in the constellation of Virgo (The Virgin). It may seem to have no discernible structure, but IC 3583 has been found to have a bar of stars running through […]

Dawn Spacecraft Views Craters Takel and Cozobi

This newly released image from NASA’s Dawn Spacecraft shows craters Takel and Cozobi on Ceres. The craters Takel and Cozobi are featured in this image of Ceres from NASA’s Dawn spacecraft. Takel is the young crater with bright material on the left of this image, and Cozobi is the sharply defined crater just below center. […]

Cassini Views Saturn's 'Watercolor' Swirls

In this newly released image from the Cassini Spacecraft you can see Saturn’s north polar region, which somewhat resemble the brushwork in a watercolor painting. Each latitudinal band represents air flowing at different speeds, and clouds at different heights, compared to neighboring bands. Where they meet and flow past each other, the bands’ interactions produce […]

Hubble Views Irregular Dwarf Galaxy NGC 4789A

This newly released Hubble image shows irregular dwarf galaxy NGC 4789A, which is located in the constellation of Coma Berenices. It certainly lives up to its name — the stars that call this galaxy home are smeared out across the sky in an apparently disorderly and irregular jumble, giving NGC 4789A a far more subtle […]

New Image of Wind Carved Rock on Mars

This newly released NASA image shows wind carved rock on the surface of Mars. The distinctively fluted surface and elongated hills in this image in Medusae Fossae on Mars are caused by wind erosion of a soft fine-grained rock. Called yardangs, these features are aligned with the prevailing wind direction. This wind direction would have […]

Hubble Image of the Week NGC 1222

This newly released Hubble image shows lenticular galaxy NGC 1222, which is located 100 milion light-years away. NGC 1222, seen in this image taken with the Wide Field Camera 3 on board the NASA/ESA Hubble Space Telescope (HST), is a galaxy with a rather eventful story to tell. NGC 1222 has been described as a […]

New-Pillars-of-Destruction-Images

Using the MUSE instrument on ESO’s Very Large Telescope, astronomers reveal new observations of vast pillar-like structures within the Carina Nebula. The different pillars analyzed by an international team seem to be pillars of destruction — in contrast to the name of the iconic Pillars of Creation in the Eagle Nebula, which are of similar […]

NASA’s SDO Catches a Lunar Transit

NASA’s Solar Dynamics Observatory experienced a partial solar eclipse in space when it caught the moon passing in front of the sun. The moon’s shadow obstructs SDO’s otherwise constant view of the sun, and the shadow’s edge is sharp and distinct, since the moon has no atmosphere which would distort sunlight. From SDO’s point of […]

New Cassini View from Above Saturn

NASA’s Cassini Spacecraft views Saturn from above. Saturn appears as a serene globe amid tranquil rings in this view from NASA’s Cassini spacecraft. In reality, the planet’s atmosphere is an ever-changing scene of high-speed winds and evolving weather patterns, punctuated by occasional large storms. The rings, consist of countless icy particles, which are continually colliding. […]

Hubble Views Star Cluster NGC 362

This newly released Hubble image shows globular cluster NGC 362. Globular clusters offer some of the most spectacular sights in the night sky. These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters — and the one shown in this NASA/ESA […]

New Hubble Image of the Crab Nebula

This newly released Hubble image of the Crab Nebula shows the eerie glow of a dead star, which exploded long ago as a supernova. But don’t be fooled; this ghoulish-looking object still has a pulse. Buried at its center is the star’s tell-tale heart, which beats with rhythmic precision. The “heart” is the crushed core […]

Astronomers Study Saturn's Fluid Dynamics

Astronomers are using Saturn’s clouds to study fluid dynamics, which seeks to understand the motion of gases and liquids. Saturn’s lack of a solid planetary surface (as on Earth, Mars or Venus) means that its atmosphere is free to flow around the planet essentially without obstruction. This is one factor that generates Saturn’s pattern of […]

Hubble Image of the Red Spider Nebula

This newly released Hubble image shows the Red Spider Nebula, which is located some 3,000 light-years away in the constellation of Sagittarius. Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion […]

VLT Provides Highest Resolution Image of Eta Carinae

Using the Very Large Telescope Interferometer, a team of astronomers reveals the Eta Carinae star system in the greatest detail ever achieved. High-resolution images reveal new and unexpected structures within the Eta Carinae binary system, including in the area between the two stars where extremely high velocity stellar winds are colliding. These new insights into […]
