Stunning Image of ISS Taken From the Ground Shows two Spacewalking Astronauts

In our age, we’ve grown accustomed to pictures of astronauts inside the International Space Station, as they float in zero-G and tend their science experiments. We’re even getting used to images of spacewalking astronauts. But this is something new.

This is Where the Mars Sample Return Mission Could be Landing

This image was acquired based on a hopeful scenario in which the Perseverance rover has an extended mission or two and travels outside of Jezero Crater to explore terrains to the west. In this scenario, the decision could be made to land the Mars Sample Return (MSR) mission here to pick up samples collected by Perseverance. MSR will probably not land here, but acquisition of a HiRISE stereo pair provides the data needed to assess the risk of landing. The cutout shows that there are diverse colors and textures, so this would be an interesting region to explore. Image Credit: NASA/JPL/UArizona

NASA’s Perseverance Rover is busy exploring Jezero Crater on Mars. Part of its mission is to collect samples for retrieval by a future mission. NASA and the ESA haven’t determined where the sample return mission will land yet.

That depends on the Perseverance mission and how it spends the rest of its time on Mars. But we know of one possible—albeit ambitious—landing spot: just west of Jezero Crater.

These are Star Dunes on Mars, Formed When the Wind Comes From Many Different Directions

An amazing aspect of Mars that is captured in many HiRISE images is geologic diversity within a small area. This image, of a crater in the Tyrrhena Terra region, was targeted to look at the geologic aspects of possible clays detected with the CRISM instrument. Image Credit: NASA/JPL/UArizona

Missions to Mars are expensive, even orbiters. They’re there to do science, not take pretty pictures. But sometimes Mars’ beauty is captured inadvertently, usually with some science mixed in.

That’s the case with this picture of star dunes captured by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.

Wondering About the 6 Rays Coming out of JWST's Test Image? Here's why They Happen

At the Space Telescope Science Institute (STSI) in Baltimore, Maryland, NASA engineers are busy aligning the mirrors and instruments on the James Webb Space Telescope (JWST). In the meantime, the mission team has provided us with another glimpse of what this observatory – a successor to the venerable Hubble Space Telescope – will see once it is fully operational. The latest teaser is a “telescope alignment evaluation image” of a distant star that looks red and spiked!

North Korea Releases Pictures of Earth They Say Were Taken From Space

North Korea released some pictures they say come from their recent missile test. The missile they tested—the intermediate-range Hwasong-12—can reach the U.S. territory of Guam. According to most North Korea observers, the country hopes the tests will bring the U.S. back to the negotiating table.

Latest Hubble Image Shows the Star-Forming Chamaeleon Cloud

Stars form inside vast collections of molecular hydrogen called molecular clouds, sometimes called stellar nurseries or star forming regions. Instabilities in the clouds cause gas to collapse in on itself, and when enough material gathers and the density reaches a critical stage, a star begins its life of fusion.

But molecular clouds aren’t always alone. They often exist in association with other clouds, and astronomers call these formations Cloud Complexes. The Chamaeleon Cloud Complex (CCC) is one of the closest active star forming regions to Earth. It’s further divided into three substructures called dark clouds, or dark nebula. They are Chamaeleon 1 (Cha1), Chamaeleon 2, and Chamaeleon 3.

NASA created a new composite image of Chamaeleon 1 based on Hubble images, and the vivid panorama brings Chamaeleon I to life.

Ice Peeks out of a Cliffside on Mars

This area, on the western edge of Milankovic Crater on Mars, has a thick deposit of sediment that covers a layer rich in ice. The ice is not obvious unless you look in color. In the red-green-blue images that are close to what the human eye would see, the ice looks bright white, while the surroundings are a rusty red. The ice stands out even more clearly in the infrared-red-blue images where it has a striking bluish-purple tone while the surroundings have a yellowish-grey color. The ice-rich material is most visible when the cliff is oriented east-west and is shielded from the sun as it arcs through the sky to the south. Image Credit: NASA/JPL/UArizona

The HiRISE (High-Resolution Imaging Science Experiment) camera on the Mars Reconnaissance Orbiter has captured another beauty. This time the image shows water ice peeking out from a cliffside on Mars. A layer of sediment obscures most of the ice, but fingers of it are visible.

Nancy Grace Roman Telescope Will do its Own, Wide-Angle Version of the Hubble Deep Field

This synthetic image visualizes what a Roman ultra-deep field could look like. The 18 squares at the top of this image outline the area Roman can see in a single observation, known as its footprint. The inset at the lower-right zooms into one of the squares of Roman's footprint, and the inset at the lower-left zooms in even further. The image, which contains more than 10 million galaxies, was constructed from a simulation that produced a realistic distribution of the galaxies in the universe.

Remember the Hubble Space Telescope’s Deep Field and Ultra-Deep Field images?

Those images showed everyone that what appears to be a tiny, empty part of the sky contains thousands of galaxies, some dating back to the Universe’s early days. Each of those galaxies can have hundreds of billions of stars. These early galaxies formed only a few hundred million years after the Big Bang. The images inspired awe in the human minds that took the time to understand them. And they’re part of history now.

The upcoming Nancy Grace Roman Space Telescope (NGRST) will capture its own version of those historical images but in wide-angle. To whet our appetites for the NGRST’s image, a group of astrophysicists have created a simulation to show us what it’ll look like.

A New Image Reveals Orion’s Flame Nebula in Infrared

Do not let the image and the name of the depicted cosmic object fool you! What you see in this picture is not a wildfire, but the Flame Nebula and its surroundings captured in radio waves. The Flame Nebula is the large feature on the left half of the central, yellow rectangle. The smaller feature on the right is the reflection nebula NGC 2023. To the top right of NGC 2023, the iconic Horsehead Nebula seems to emerge heroically from the “flames”. The three objects are part of the Orion cloud, a giant gas structure located between 1300 and 1600 light-years away. The different colours indicate the velocity of the gas. The Flame Nebula and its surroundings are moving away from us, with the red clouds in the background receding faster than the yellow ones in the foreground. The image in the rectangle is based on observations conducted with the SuperCam instrument on the ESO-operated Atacama Pathfinder Experiment (APEX) on Chile’s Chajnantor Plateau. The background image was taken in infrared light with ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) at the Paranal Observatory in Chile.

The ESO has released some stunning new images of Orion’s Flame Nebula. They’re from a few years ago but are newly processed as part of the Orion cloud complex study. The images have led to discoveries in the often-observed Orion cloud complex.

This is a Classic Example of a Reflection Nebula, Where the Reflected Light From Young Hot Stars Illuminates a Protostellar Cloud of Gas and Dust

This NASA Hubble Space Telescope image captures a portion of the reflection nebula IC 2631 that contains a protostar, the hot, dense core of a forming star that is accumulating gas and dust.

The interplay of energy and matter creates beautiful sights. Here on Earth, we enjoy rainbows, auroras, and sunsets and sunrises. But out in space, nature creates extraordinarily dazzling structures called nebulae that can span hundreds of light-years. Nebulae are probably the most beautiful objects out there.

While searching for young stars and their circumstellar disks, Hubble captured a classic reflection nebula.
