New Image of Saturn's Moon Tethys

NASA’s Cassini Spacecraft views Saturn’s moon Tethys. Saturn’s moon Tethys appears to float between two sets of rings in this view from NASA’s Cassini spacecraft, but it’s just a trick of geometry. The rings, which are seen nearly edge-on, are the dark bands above Tethys, while their curving shadows paint the planet at the bottom […]

NASA’s Juno Spacecraft Burns for Jupiter

Launched in 2011, the Juno spacecraft will arrive at Jupiter in 2016 to study Jupiter from an elliptical, polar orbit. NASA’s solar-powered Juno spacecraft successfully executed a maneuver to adjust its flight path today, February 3. The maneuver refined the spacecraft’s trajectory, helping set the stage for Juno’s arrival at the solar system’s largest planetary […]

Small Asteroid 2013 TX68 to Pass Close to Earth March 5

Asteroid 2013 TX68 (which flew past Earth at a comfortable distance of about 1.3 million miles two years ago) will safely fly by our planet again in a few weeks, though this time it may be much closer. During the upcoming March 5 flyby, asteroid 2013 TX68 could fly past Earth as far out as […]

Saturn's B Rings Less than Meets the Eye

New data from NASA’s Cassini Spacecraft reveals that there is little correlation between how dense the rings of Saturn might appear to be — in terms of its opacity and reflectiveness — and the amount of material they contain. It seems intuitive that an opaque material should contain more stuff than a more translucent substance. […]

Hubble Views NGC 1487

This newly released Hubble image shows peculiar galaxy NGC 1487, which is about 30 million light-years away in the southern constellation of Eridanus. Rather than viewing a celestial object, it is actually better to think of this as an event. Here, we are witnessing two or more galaxies in the act of merging together to […]

Hubble Space Telescope Shows the Inner Region of Abell 1689

New research from NASA’s Jet Propulsion Laboratory suggests that the internal structure of a galaxy cluster is linked to the dark matter environment surrounding it. This is the first time that a property besides the mass of a cluster has been shown to be associated with surrounding dark matter. Dark matter is a mysterious cosmic […]

Astronomers Reveal Evidence of Distant Gas Giant Planet in Our Solar System

What is Planet 9? NASA scientists take a closer look at the newly discovered evidence from Caltech. Caltech researchers have found evidence suggesting there may be a “Planet X” deep in the solar system. This hypothetical Neptune-sized planet orbits our sun in a highly elongated orbit far beyond Pluto. The object, which the researchers have […]

Cassini Captures a Half-Lit View of Enceladus

NASA’s Cassini Spacecraft delivers another great image of Enceladus. This half-lit view of Enceladus bears a passing resemblance to similar views of Earth’s own natural satellite, but the similarities end there. Earth’s rocky moon is covered in dark, volcanic basins and brighter, mountainous highlands — both exceedingly ancient. The surface of icy Enceladus is uniformly […]

Star Cluster Trumpler 14

This Hubble image features star cluster Trumpler 14 – one of the largest gatherings of hot, massive and bright stars in the Milky Way. Single stars are often overlooked in favor of their larger cosmic cousins — but when they join forces, they create truly breathtaking scenes to rival even the most glowing of nebulae […]

Hubble Views Galaxy LO95 0313-192

This newly released Hubble image shows spiral galaxy LO95 0313-192, which is locate roughly one billion light-years away. Despite its unassuming appearance, the edge-on spiral galaxy captured in the left half of this NASA/ESA Hubble Space Telescope image is actually quite remarkable. Located about one billion light-years away in the constellation of Eridanus, this striking […]

Rover Curiosity Tastes Scooped, Sieved Sand

NASA’s Curiosity Mars Rover continues its campaign to study active sand dune on Mars, scooping and analyzing samples. At its current location for inspecting an active sand dune, NASA’s Curiosity Mars rover is adding some sample-processing moves not previously used on Mars. Sand from the second and third samples the rover is scooping from “Namib […]

New Cassini View of Janus and Tethys

This image from the Cassini Spacecraft demonstrates the main difference between small moons and large ones. It’s all about the moon’s shape. Moons like Tethys (660 miles or 1,062 kilometers across) are large enough that their own gravity is sufficient to overcome the material strength of the substances they are made of (mostly ice in […]

NASA Details Record-Shattering Global Warm Temperatures from 2015

&nbs According to independent analyses by NASA and the National Oceanic and Atmospheric Administration, Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880. Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been […]

Van Allen Probes Revolutionize View of Radiation Belts

New research from NASA’s Van Allen Probes reveals that the shape of the Van Allen Belts can vary from a single, continuous belt with no slot region, to a larger inner belt with a smaller outer belt, to no inner belt at all. About 600 miles from Earth’s surface is the first of two donut-shaped […]

New Hubble Image of NGC 5408

This newly released Hubble image shows galaxy NGC 5408, which is located 16 million light-years away. Most galaxies possess a majestic spiral or elliptical structure. About a quarter of galaxies, though, defy such conventional, rounded aesthetics, instead sporting a messy, indefinable shape. Known as irregular galaxies, this group includes NGC 5408, the galaxy that has […]
