A Road to the Stars | European Southern Observatory

A Road to the Stars | European Southern Observatory


A stunning night view, taken close to the 1.54m Danish Telescope and the 3.6m telescope on the road at La Silla, shows the Milky Way above the horizon, accompanied by the Magellanic Clouds.

ESO’s 3.6m Telescope, seen here atop a hill at the center of the image, is home to HARPS, an instrument dedicated to the discovery of planets outside the Solar System via the radial velocity method. This method enables the detection of a planet by measuring the wobbling motion of the central star caused by the gravitational pull of the planet itself. 

The towers on the left are the support structures of the BlackGEM telescopes, which had not been installed yet when this image was taken. BlackGEM is an array of telescopes that will search for the light emitted by the optical counterparts of the most powerful gravitational-wave sources, namely colliding neutron stars and black holes. 

On the right of the image, we see the Large and Small Magellanic Clouds, two irregular dwarf galaxies orbiting the Milky Way at a distance of approximately 160,000 and 200,000 light-years, respectively. In the Mapuche culture of south-central Chile, these neighboring galaxies were known as lafken, labken or künchalabken (“the lagoons”) as well as rünanko (“the water wells”). [1]

The red filamentary emission stretching across the sky in the horizon is called airglow, which is light naturally emitted by atoms and molecules in the atmosphere through various physical and chemical processes. Despite showing up prominently in this image, airglow is invisible to the unaided eye.

A Not-So-Close Galactic Encounter | Hubble

A Not-So-Close Galactic Encounter | Hubble


The twin galaxies NGC 4496A and NGC 4496B dominate the frame in this image from the NASA/ESA Hubble Space Telescope. Both galaxies lie in the constellation Virgo, but despite appearing side-by-side in this image they are at vastly different distances from both Earth and one another. NGC 4496A is 47 million light-years from Earth while NGC 4496B is 212 million light-years away. The enormous distances between the two galaxies mean that the two cannot interact, and they only appear to overlap owing to a chance alignment. 

Chance galactic alignments such as this provide astronomers with the opportunity to delve into the distribution of dust in these galaxies. Galactic dust adds to the beauty of astronomical images—it can be seen in this image as the dark tendrils threading through both NGC 4496A and NGC 4496B—but it also complicates astronomers’ observations. Dust absorbs starlight, making stars seem dimmer and shifting their light towards longer wavelengths, a process that astronomers refer to as “reddening” (not the same thing as redshift). By carefully measuring how starlight from background galaxies is affected by dust in intervening galaxies, astronomers can map out where the dust is in the foreground galaxy’s spiral arms. The resulting “dust maps” help astronomers calibrate measurements of everything from cosmological distances to the types of stars populating galaxies.

NASA's Space to Ground: Shipping and Receiving

NASA's Space to Ground: Shipping and Receiving

Week of February 25, 2022: NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station (ISS). 

This is Northrop Grumman’s 17th contracted resupply mission under the second Commercial Resupply Services contract with NASA. NASA astronaut Raja Chari commanded the Canadarm2 robotic arm to capture the U.S. Cygnus cargo craft. Robotics controllers on the ground took over shortly afterwards and remotely guided the Canadarm2 with Cygnus attached and installed it to the Unity module to begin three months of cargo operations. 

Cygnus launched atop an Antares rocket at 12:40 p.m. EST Saturday, Feb. 19, 2022, from NASA’s Wallops Flight Facility in Virginia. At about 4:44 a.m., NASA astronaut Raja Chari, along with NASA astronaut Kayla Barron as backup, captured Cygnus, carrying 8,300 pounds of research, hardware, and science experiments to the International Space Station.

Each Cygnus spacecraft is named in honor of an individual who has made great contributions to human spaceflight. For the NG-17 mission, Cygnus celebrates Piers Sellers, a former NASA astronaut and renowned climate scientist.

Cygnus will remain at the International Space Station until May 2022 before it deploys CubeSats, then disposes of several thousand pounds of trash during its re-entry into Earth’s atmosphere, which will result in its destruction.

The International Space Station Program’s greatest accomplishment is as much a human achievement as it is a technological one—how best to plan, coordinate, and monitor the varied activities of the Program’s many organizations.

An international partnership of space agencies provides and operates the elements of the ISS. The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada. The ISS has been the most politically complex space exploration program ever undertaken.

Clair de Lune by Debussy | Artemis Music

Clair de Lune by Debussy | Artemis Music

This special rendition of Debussy's Clair de Lune (‘Moonlight’), commissioned by Artemis Music LLC and performed by internationally renowned pianist Wing-Chong Kam, was beamed into space and orbited the Earth aboard the International Space Station on July 28th, 2021, in commemoration of the timeless beauty of Claude Debussy's masterpiece and in celebration of the unity of music for all humankind. Visualizations of the Moon courtesy of the NASA Scientific Visualizations Studio, with digital 3D data captured by NASA’s Lunar Reconnaissance Orbiter (LRO).

The cosmic perspective of space inspires a cognitive shift in humans. Debussy’s Clair de Lune perhaps comes as close as possible to stirring the emotions of awe and wonder experienced by space travelers. 

The universe is full of music, and we humans are learning how to use music to not only understand the science of the universe, but to grasp our place in it.

“Music is what happens in the space between the notes.”

- Claude Debussy

NASA's Mars Curiosity Rover Spots Clouds over Mont Mercou | JPL

NASA's Mars Curiosity Rover Spots Clouds over Mont Mercou | JPL

NASA’s Curiosity Mars rover captured these clouds just after sunset on March 19, 2021, the 3,063rd Martian day, or sol, of the rover’s mission. The image is made up of 21 individual images stitched together and color corrected so that the scene appears as it would to the human eye. The clouds are drifting over “Mont Mercou,” a cliff face that Curiosity has been studying.

The rover captured the image using its Mast Camera, or Mastcam. Malin Space Science Systems in San Diego built and operates Mastcam. A division of Caltech, NASA’s Jet Propulsion Laboratory in Southern California built the Curiosity rover and manages the Curiosity rover for the agency’s Science Mission Directorate in Washington.

The Curiosity Rover landed in Mars' Gale Crater on August 6, 2012.

Curiosity's View From the Top of the 'Greenheugh Pediment'
​Stitched together from 28 images, this view from NASA's Curiosity Mars rover was captured on April 9, 2020, the 2,729th Martian day, or sol, of the mission after the rover ascended a steep slope, part of a geologic feature called "Greenheugh Pediment." In the foreground is the crusty sandstone cap that stretches the length of the pediment, forming an overhanging ledge in some parts. At center is the "clay-bearing unit," a region with a unique story to tell about the history of water on Mount Sharp, the 3-mile-tall (5-kilometer-tall) mountain Curiosity has been ascending since 2014. In the distance at the top of the image is the floor of Gale Crater, which is 96 miles (154 kilometers) wide.

The rover's Mast Camera, or Mastcam, provided the panorama. Malin Space Science Systems in San Diego built and operates Mastcam. A division of Caltech, NASA's Jet Propulsion Laboratory in Southern California built the Curiosity rover and manages the Mars Science Laboratory mission for the agency's Science Mission Directorate in Washington.

The panorama has been white-balanced so that the colors of the rock materials resemble how they would appear under daytime lighting conditions on Earth.

Martian Winds at Work | ESA Mars Express

Martian Winds at Work | ESA Mars Express




These images from the European Space Agency's Mars Express orbiter shows part of possibly the largest single source of dust on Mars: a wind-sculpted feature known as the Medusae Fossae Formation, or MFF.

The MFF is not only a veritable dust factory, but also remarkably extensive—it is the largest sedimentary deposit on the planet and stretches out discontinuously for more than 5,000 km, covering an area about the size of India. It is named for the Greek mythological Gorgon Medusa, who was able to turn those who looked into her eyes to stone, with the suffix ‘fossae’ being Latin for trenches or hollows.

The formation is found along the boundary between Mars’ southern highlands and northern lowlands (known as the martian dichotomy), and sits between the planet’s two most prominent volcanic regions (Tharsis and Elysium). It also contains the Eumenides Dorsum mountain range, the edges of which can be seen in the gentle elevation extending out of the bottom right of the frame (northeast).

Wind is a powerful sculptor on the Red Planet—as well as here on Earth. Mars Express has spied several other landscapes on Mars that have been significantly shaped by wind, such as Nili Fossae, Arabia Terra, Syrtis Major, southern dunes, and Schiaparelli crater.

In fact, this region likely formed as a result of wind moving material around on Mars’ surface. The MFF is thought to consist of ash released by the volcanoes in the nearby Tharsis region—including Olympus Mons, the largest volcano in the Solar Systemthat has been deposited either through the air or via fast-moving ‘pyroclastic’ flows of lava, gas and rocky debris.

The crescent-shaped depressions are also the doing of martian winds. These saucer- or trough-shaped hollows, known as blowouts, are apparently carved into the sand by wind erosion. To create a blowout, sand-laden wind whips along and erodes the smooth surface until it hits an obstacle—a buried object such as a rock or more resistant patch of sediment, for example. The wind is then forced around and beneath the object, creating an eddy, before finally heading back upwards, lifting sand with it as it goes.

Wind erosion is thought to be the latest stage of erosional processes acting on the MFF. This is evidenced by the general lack of craters seen on the formation’s surface; if wind erosion had occurred long ago only, we would expect to see more recent craters atop the wind-sculpted terrain. Overall, the fact that only a few craters are visible here, sitting alongside underlying older rock that has subsequently been covered and draped in dust, implies that the region’s surface is young.

Exploring the surface features and geology of Mars is a key objective of Mars Express. Launched in 2003, the spacecraft has been orbiting the Red Planet for nearly two decades; it has since been joined by the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO), which arrived in 2016, while the ExoMars Rosalind Franklin rover and its accompanying surface science platform are scheduled for launch in 2022. Together, this fleet of martian explorers is working towards a fuller understanding of Mars and its intriguing landscapes.

NASA’s James Webb Space Telescope: Exploring the TRAPPIST-1 System

NASA’s James Webb Space Telescope: Exploring the TRAPPIST-1 System

During its first operating cycle, the James Webb Space Telescope will set its sights on the TRAPPIST-1 system, an incredible collection of seven rocky exoplanets 41 light years away from Earth.

Astrobiologists, like Dr. Giada Arney from NASA's Goddard Space Flight Center, are excited about this system because TRAPPIST-1 is a perfect laboratory for studying habitability! It consists of seven rocky planets, distributed across the system’s habitable zone, or the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets. Webb will characterize the atmospheres of these planets and help scientists learn more about planetary formation and habitability.
