A Mesa in Noctis Labyrinthus: This image from NASA’s Mars Reconnaissance Orbiter shows a small mesa, one of several surrounded by sand dunes in Noctis Labyrinthyus, an extensively fractured region on the western end of Valles Marineris on Mars.

Heavily eroded, with clusters of boulders and sand dunes on its surface, this layered mesa is probably comprised of sedimentary deposits that are being exhumed as it erodes. The layers themselves are visible as faint bands along the lower left edge of the mesa.

Watercolor world! When imaged at infrared wavelengths that pierce the planet’s upper haze layer, the high-speed winds of Saturn’s atmosphere produce watercolor-like patterns. With no solid surface creating atmospheric drag, winds on Saturn can reach speeds of more than 1,100 miles per hour (1,800 kilometers per hour) — some of the fastest in the solar system.

The image was taken with the Cassini spacecraft wide-angle camera on Dec. 2, 2016, with a combination of spectral filters which preferentially admits wavelengths of near-infrared light centered at 728 nanometers.

‘Twas the night before launch… NASA commercial cargo provider Orbital ATK is on track for its seventh commercial resupply services mission to the International Space Station for 11:11 a.m. EDT Tuesday at the start of a 30-minute launch window. Launching on a United Launch Alliance Atlas V rocket, the uncrewed Cygnus spacecraft will carry more than 7,600 pounds of science research, crew supplies and hardware to the orbiting laboratory in support of the crew members.

NASA TV launch coverage will begin at 10 a.m. EDT on air and streaming at https://www.nasa.gov/live. NASA TV’s YouTube channel will debut full, 360 coverage of the launch at http://youtube.com/nasatelevision

LIFTOFF! United Launch Alliance’s Atlas V rocket, carrying Orbital ATK’s #Cygnus cargo vehicle, left Earth at 11:11 a.m. EDT to deliver supplies and research to the International Space Station. Carrying over 7,600 pounds of science gear and crew supplies, it will arrive for docking early Saturday morning.
Highlights from the new experiments will include studies on cancer-fighting drugs, crystal growth and atmospheric reentry.

Arrhythmic beating of a black hole heart: At the center of the Centaurus galaxy cluster, there is a large elliptical galaxy called NGC 4696. Deeper still, there is a supermassive black hole buried within the core of this galaxy. New data from our Chandra X-ray Observatory and other telescopes has revealed details about this giant black hole.

The edge of Jupiter: This enhanced color Jupiter image, taken by the JunoCam imager on our Juno spacecraft, showcases several interesting features on the apparent edge (limb) of the planet. Prior to Juno’s fifth flyby over Jupiter’s mysterious cloud tops, members of the public voted on which targets JunoCam should image. This picture captures not only a fascinating variety of textures in Jupiter’s atmosphere, it also features three specific points of interest: «String of Pearls,» «Between the Pearls,» and «An Interesting Band Point.» Also visible is what’s known as the STB Spectre, a feature in Jupiter’s South Temperate Belt where multiple atmospheric conditions appear to collide.

NASA astronaut Jack Fischer (@astro2fish) and cosmonaut Fyodor Yurchikhin of the Russian space agency Roscosmos launched into orbit to begin their four and a half month mission on the International Space Station. After a six-hour flight, their Soyuz arrived at the International Space Station (@ISS) at 9:18 a.m. EDT Thursday, where the two new crew members joined Commander Peggy Whitson of NASA and Flight Engineers Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency). The crew members will conduct approximately 250 science investigations in fields such as biology, Earth science, human research, physical sciences and technology development.

Behold, two spiral galaxies! Astronomers used the Hubble Space Telescope to take a portrait of a stunning pair of spiral galaxies. This starry pair offers a glimpse of what our Milky Way galaxy would look like to an outside observer. These galaxies look quite different because we see them angled at different positions on the sky. They are actually very similar in terms of their structure and contents.` Both galaxies are approximately 55 million light-years away and reside in a cluster of nearly 2,000 galaxies.
A typical spiral galaxy has arms of young stars that wind outward from its center. The bright arms are regions of intense star formation. Such galaxies have a central bulge and are surrounded by a faint halo of stars. Many spiral galaxies also have bars that extend from the central bulge to the arms.

For us here at NASA, Earth Day is every day! With a fleet of spacecraft orbiting our home planet collecting data on everything from the air we breathe to natural disasters that impact our lives, Earth is always in focus. Join us as we celebrate our home with beautiful views from our unique vantage point of space.

Cascading Loops: An active region that had just rotated into view blasted out a coronal mass ejection, which was immediately followed by a bright series of post-coronal loops seeking to reorganize that region’s magnetic field (April 19, 2017). We have observed this phenomenon numerous times, but this one was one of the longest and clearest sequences we have seen in years. The bright loops are actually charged particles spinning along the magnetic field lines. The action was captured in a combination of two wavelengths of extreme ultraviolet light over a period of about 20 hours.
