Aurora over Northern Norway | Earth Science

Aurora over Northern Norway | Earth Science



Astrophotographer Ivar Sandland: "Moonlight level at 80% in crispy cold winter and snow. No need for a headlamp hiking near Bodø at night."

Also known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

A Galactic Quartet: NGC 6845 in Telescopium | Gemini South Telescope

A Galactic Quartet: NGC 6845 in Telescopium | Gemini South Telescope


A quartet of interacting galaxies is captured in this observation from Gemini South, one of the twin telescopes of the International Gemini Observatory, operated by the United States National Science Foundation (NSF) NOIRLab. The four galaxies in this image are collectively known as NGC 6845, and lie roughly 270 million light-years from Earth in a constellation named, appropriately, Telescopium. This constellation is one of a handful named after scientific instruments rather than animals or mythological figures.

The galaxies in NGC 6845 come in two varieties. The pair of galaxies at the top of this image are well-defined spiral galaxies whereas the two below them are disk-shaped lenticular galaxies. Connecting the galaxies is evidence of star-forming regions and filaments made of stars detached from their original galaxies. Being relatively close neighbors, the galaxies in NGC 6845 are interacting. These gravitational interactions are subtly distorting the galaxies in NGC 6845, and astronomers believe that the two spiral galaxies will eventually evolve into lenticular galaxies.

SpaceX Starlink Satellites Reflecting Sunlight | International Space Station

NASA astronaut and former International Space Station flight engineer Don Pettit: "SpaceX Starlink satellites flashing like shooting stars with time exposure. Dozens could be seen in rapid succession near our orbital dawn and dusk, when their solar panels reflected sunlight at the proper angles!"

NASA astronaut Don Pettit returned to Earth on April 19, 2025, concluding a seven-month science mission aboard the International Space Station. Pettit spent 220 days in space, earning him a total of 590 days in space over the course of his four spaceflights. He orbited the Earth 3,520 times, traveling 93.3 million miles in low-Earth orbit.

Spiral Galaxies NGC 3314a and b: "Caught in a spiral" in Hydra | ESO

Spiral Galaxies NGC 3314a and b: "Caught in a spiral" in Hydra | ESO


The image shows a pair of overlapping spiral galaxies, NGC 3314a and b, in the top left, caught in a majestic cosmic dance—captured by European Southern Observatory’s VLT Survey Telescope (VST).

However, do not let the perspective fool you! 

They are, in fact, not interacting at all. The two galaxies, located between 117 and 140 million light-years away in the constellation of Hydra, are actually physically unrelated and only appear to overlap when viewed from Earth. This unique alignment gives astronomers the opportunity to measure many properties of the galaxies, such as how dust absorbs starlight, and hence gain insight into their composition and evolution.

There is another hidden secret in this picture if you look closely at the lower right region. Beyond this stunning cosmic dance you will find a faint yellowish smudge, the signature of an ultra-diffuse galaxy (UDG). UDGs are objects as large as the Milky Way but with 100–1,000 times fewer stars. These galaxies are extremely faint and lack star-forming gas, which makes them appear almost like a smudge in the night sky. This UDG, named UDG 32, is one of the faintest and most spread out galaxies in the Hydra I cluster.

This image was taken as part of a much larger project, the VST Early-type Galaxy Survey (VEGAS), whose goal is to investigate very faint structures in galaxy clusters—large groups of galaxies held together by gravity. The study, led by Enrichetta Iodice from the Istituto Nazionale di Astrofisica in Italy, suggests that UDG 32 may have formed out of the filaments stemming from NGC 3314a, but more observations are needed to confirm this.

Wide-view: Galaxy Cluster Abell 3827 in Indus—Mass Map | Victor Blanco Telescope

Wide-view: Galaxy Cluster Abell 3827 in IndusMass Map | Victor Blanco Telescope

Galaxy clusters are massive collections of hundreds or even thousands of galaxies, bound together by their mutual gravitational attraction. Using the Dark Energy Camera (DEC) at Cerro Tololo Inter-American Observatory, a Program of the United States National Science Foundation (NSF) NOIRLab, astronomers are measuring weak gravitational lensing to map the distribution of mass in nearby galaxy clusters. As well as producing remarkable images like this one, the information will shed light on the relationships between the constituent parts of nearby galaxy clusters, such as gas, stellar populations, and dark matter.

The galaxy cluster Abell 3827 is the subject of this striking image. In addition to featuring a field of galaxies and foreground stars, the image is overlaid with a map with hues of red, blue and purple. Though they are attractive, these colors are not for decoration—they represent the distribution of mass in the heart of Abell 3827 with red showing the largest mass concentration.

'Eyes in The Sky': Mrk 739 in Leo—Galaxies & Supermassive Black Holes Merge

'Eyes in The Sky': Mrk 739 in Leo—Galaxies & Supermassive Black Holes Merge

Do you ever get the feeling that you're being watched? 

This friendly-looking object is the result of two galaxies merging into one another, complete with a pair of eyes hiding two growing supermassive black holes and a swirling grin. Such mergers are rare in our galactic neighborhood. Mrk 739 is close enough (astronomically speaking) to study the event in detail, and thus gain a better understanding of the dramatic processes that take place during these cosmic mergers.

Note: The Markarian (Mrk) galaxies are a class of galaxies that have nuclei with excessive amounts of ultraviolet emissions compared with other galaxies. 

By using the MUSE instrument on the European Southern Observatory (ESO) Very Large Telescope (VLT), the team of astronomers, led by master’s student Dusán Tubín at the Pontificia Universidad Católica de Chile, were able to study the effects of the merger and the radiation emitted by the growing gigantic black holes. Their study answers questions about the motion of the galaxies, the age of their stars, and the elements they are made up of. They have found that one of these galaxies is much older than its companion, and that their merging process is at an early stage.

MUSE is a 3D spectrograph that takes images—known as “datacubes”—of the object being observed over thousands of wavelengths. With MUSE, astronomers are therefore able to map in great detail the properties of the objects they study, because each individual pixel contains an impressive amount of information. Obtaining these exciting insights into galaxy merging and evolution with MUSE is enough to make anyone smile.

From Sea to Stars: China's First Sea-based Spaceport

From Sea to Stars: China's First Sea-based SpaceportHome of Orienspace

On the shores of the Yellow Sea stands China's first rocket launch vessel—the very own "starship" setting sail toward the cosmos. Since 2019, it has launched Long March 11, Gravity-1, Ceres-1 and more.

Orienspace, a private Chinese rocket manufacturer, successfully launches their 30-meter-tall Gravity 1 Y2 commercial carrier rocket with four solid-rocket boosters (SRBs) off the coast of Haiyang in east China's Shandong Province from this sea-based space port. Gravity 1 is currently the world's largest and most powerful commercial solid-propellant rocket that produces 600 tonnes of thrust at liftoff. With a liftoff weight of 405 metric tons and a thrust of 600 tons, the rocket can carry a spacecraft weighing up to 6.5 tons to a low-Earth orbit, or 4.2 tons to a typical sun-synchronous orbit at an altitude of 500 kilometers, according to Orienspace—founded in 2020 by a group of veteran researchers from State-owned space enterprises.

Gravity 1 is the most powerful commercial rocket in China today.

Its liftoff weight and thrust surpass those of the European Space Agency's Vega-C, previously the world's most powerful solid-propellant rocket.

In addition, at this time, Gravity 1 is the first and only private rocket in China that has side boosters and the largest fairing, or nose cone—the top structure on a rocket that contains satellites or other payloads.

The use of solid fuel is "convenient and safe." It allows for the process of rocket assembly, testing and launch to be completed within a 5 kilometer radius, significantly reducing production time and cost.

Offshore launches offer additional advantages in terms of safety and frequency with potential for weekly launch missions using a single vessel, according to OrienSpace.

The Gravity-1 rocket structure is designed for rapid mass production. Its core and boosters have the same diameter, simplifying the manufacturing process and significantly improving manufacturing efficiency, while cutting production costs.

OrienSpace said it aimed to achieve liquid rocket recyclability and reusability within 1-2 years, increasing its carrying capacity to 15-20 tonnes and further driving down costs.

Mars: Fly around Flaugergues Crater—Animation | Europe's Mars Express Orbiter

Mars: Fly around Flaugergues CraterAnimation | Europe's Mars Express Orbiter

The European Space Agency's Mars Express takes us on a journey across the southern highlands of Mars to Flaugergues Crater. The video begins by tracking along a swathe of ground enclosed by two steeply sloping and roughly parallel cliffs—or escarpments—named Scylla Scopulus and Charybdis Scopulus (to the left and right, respectively). This 'path' of ground is called a graben, created as tectonic plates pulled apart. It measures about 75 km wide by 1 km deep.

The prominent, 150-km-wide Bakhuysen Crater can be seen to the left.

The camera continues travelling northwards, approaching Flaugergues Crater in the distance. It moves along the crater’s eastern side before circling around to the left and ending at its western rim. 

Flaugergues Crater is a roughly 240-km-wide basin found in Mars’ southern highlands, where most of the rough terrain is densely covered in craters. Half of the crater floor is also rugged, with parts rising up to elevations of around 1 kilometer. We see a valley crossing this rocky patch that was likely shaped by flows of wind and lava. 

Enjoy the flight, and be sure to view the associated map of the area. It shows the route taken by the camera and highlights the key features seen throughout the journey. These features are also indicated in the voiceover.

Cosmonaut Photos: South Georgia Island & Antarctica | International Space Station

South Georgia island
The Antarctic Peninsula

These images were shared by Expedition 74 Station Commander and Cosmonaut Sergey Kud-Sverchkov of Russia aboard the International Space Station: "A couple more photos of summer (yes, it's high summer in the Southern Hemisphere right now) Antarctica."

First Image: South Georgia is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around 1,400 kilometers (870 mi) east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around 170 kilometers (106 mi) long and has a maximum width of 35 kilometers (22 mi). The terrain is mountainous, with the central ridge rising to 2,935 meters (9,629 ft) at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as harbors.

Second Image: The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martin in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding 1,300 kilometers (810 miles) from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about 1,000 kilometers (620 miles) away across the Drake Passage. The Antarctic Peninsula is 522,000 square kilometers (202,000 sq mi) in area and is currently eighty-percent ice-covered.

Planetary Nebula Abell 24 in Canis Minor | European Southern Observatory

Planetary Nebula Abell 24 in Canis Minor | European Southern Observatory

This red-hued cloud of gas is named Abell 24, and is located in the constellation of Canis Minor (The Lesser Dog). It is something known as a planetary nebula—a burst of gas and dust created when a star dies and throws its outer layers into space. Despite the name, planetary nebulae have nothing to do with planets. The term was coined by William Herschel, that also famously discovered Uranus. In a time of low-resolution astronomy, these nebulous objects appeared to resemble giant planets swimming in a dark cosmos. 

A Sun-like star spends most of its life converting hydrogen into helium in its core. In its twilight years the star runs out of fuel and becomes unbalanced; it can no longer resist the inward crush of gravity and the core begins to collapse. The temperature in the core rises dramatically while the cooler outer layers expand, causing the entire star to bloat into a red giant. When the Sun begins its transformation into a red giant it will expand to completely engulf the innermost planets and possibly also the Earth, growing to over 250 times its current radius! Strong winds then expel the gaseous outer layers of the star, forming a shell of gas that spreads out into the vastness of space. The red giant's venting atmosphere will eventually expose its hot, luminous remnant core. This will emit fierce ultraviolet radiation and ionize the surrounding gas. This image shows the faint nebulous glow of a stellar swansong—the bright remnant of a long-dead star.

Taken with the VLT’s FOcal Reducer and Spectrograph (FORS) instrument, this image is part of the European Southern Observatory (ESO) Cosmic Gems program, an initiative to produce images of scientifically interesting and visually attractive objects using ESO telescopes for the purposes of education and public outreach. The program makes use of telescope time that cannot be used for science observations. All data collected may also be suitable for scientific purposes, and are made available to astronomers through ESO’s science archive.

Dark Matter Web in a Galactic SuperCluster: Abell 901/902 | Hubble

Dark Matter Web in a Galactic SuperCluster: Abell 901/902 | Hubble

This image reveals the distribution of dark matter in the supercluster Abell 901/902, composed of hundreds of galaxies. The image shows the entire supercluster. Astronomers assembled this photo by combining a visible-light image of the supercluster taken with the MPG/European Southern Observatory 2.2-meter telescope in La Silla, Chile, with a dark matter map derived from observations with the NASA/European Space Agency Hubble Space Telescope.

The magenta-tinted clumps represent a map of the dark matter in the cluster. Dark matter is an invisible form of matter that accounts for most of the universe's mass. The image shows that the supercluster galaxies lie within the clumps of dark matter.

Hubble cannot see the dark matter directly. Astronomers inferred its location by analysing the effect of so-called weak gravitational lensing, where light from more than 60,000 galaxies behind Abell 901/902 is distorted by intervening matter within the cluster. Researchers used the observed, subtle distortion of the galaxies' shapes to reconstruct the dark matter distribution in the supercluster.

The image was assembled by combining a visible-light image of the supercluster with a map of the dark matter distribution.

Learn more about dark matter:
https://science.nasa.gov/dark-matter/

The image is part of the Space Telescope Abell 901/902 Galaxy Evolution Survey (STAGES) covers one of the largest patches of sky ever observed by the Hubble telescope. The area surveyed is so wide that it took eighty Hubble images to cover the entire field.

Hubble's Advanced Camera for Surveys made the observations in June and July 2005 and in January 2006.

Night Lights of Armenia and Türkiye | International Space Station

Night Lights of Armenia and Türkiye | International Space Station

Yerevan, Armenia, and its modernized bright LED city lights contrast with the older amber high-pressure sodium lights of Iğdır, Türkiye (left), in this photograph from the International Space Station as it orbited 262 miles above Earth at approximately 11:12 p.m. local time. 
Villages light up the coastline in this nighttime image of Lake Sevan, one of the largest freshwater high-altitude lakes in the world, sitting at 1,900 meters above sea level in Armenia. Lake Sevan is protected as Sevan National Park for its ecological importance and for providing landlocked Armenia with most of its fish. The International Space Station was orbiting 262 miles above Earth at 11:13 p.m. local time when this photograph was taken.

These images were captured by Expedition 74 flight engineer and Japan Aerospace Exploration Agency (JAXA) astronaut Kim Yui.

Armenia, officially the Republic of Armenia, is a landlocked country in the Armenian highlands of West Asia. It is a part of the Caucasus region and is bordered by Turkey to the west, Georgia to the north, Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Yerevan is the capital, largest city and financial center. Lake Sevan is the largest body of water in Armenia and the Caucasus region. It is one of the largest freshwater high-altitude (alpine) lakes in Eurasia. The lake is situated in Gegharkunik Province, at an altitude of 1,900 m (6,234 ft) above sea level. The total surface area of its basin is about 5,000 km2 (1,900 sq mi), making up one-sixth of Armenia's territory.

Turkey, officially the Republic of Türkiye, is a country mainly located in Anatolia in West Asia, with a relatively small part called East Thrace in Southeast Europe. It borders the Black Sea to the north; Georgia, Armenia, Azerbaijan, and Iran to the east; Iraq, Syria, and the Mediterranean Sea to the south; and the Aegean Sea, Greece, and Bulgaria to the west. Iğdır is a city in the Eastern Anatolia region of Turkey. It is the seat of Iğdır Province and Iğdır District.

Sunspot Region AR 4366: A Solar Flare Factory

Sunspot Region AR 4366: A Solar Flare 'Factory'

Astrophotographer Eduardo Schaberger Poupeau: "Today at noon, from Argentina (UT−3), I captured this image of the Sun using my H-alpha telescope, at a moment of intense solar activity. The main feature is sunspot AR 4366, a true solar flare factory, which over the past 24 hours has produced 23 M-class flares and 4 X-class flares, including a powerful X8 event recorded yesterday. The photograph shows the full solar disk, allowing the enormous size of AR 4366 to be seen in its global context. At the time of capture, the region was particularly active, while multiple striking prominences are visible around the solar limb and several filaments can be seen across the disk, highlighting the strong magnetic instability currently affecting our star."

The most active sunspot of Solar Cycle 25 is turning toward Earth.

The light arriving here from the Sun at the H-alpha frequency (656.28 nanometers) comes from a rarified layer of hydrogen gas slightly above the photosphere, the bright surface of the Sun. This hydrogen layer is called the solar chromosphere, and it is invisible without using instruments to filter out brighter, competing bandwidths of light.

Occasionally, dark spots freckle the face of the Sun. These are sunspots, cooler regions on the Sun caused by a concentration of magnetic field lines. Sunspots are the visible component of active regions, areas of intense and complex magnetic fields on the Sun that are the source of solar eruptions. Sunspots can be seen on the Sun’s photosphere, or visible surface of the Sun. The number of sunspots goes up and down as the Sun goes through its natural 11-year cycle. Scientists use sunspots to help them track this cycle.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.
