Hot Binary Star System AB7 in Nearby Small Magellanic Cloud Galaxy | ESO

Hot Binary Star System AB7 in Nearby Small Magellanic Cloud Galaxy | ESO

AB7, also known as SMC WR7, is a binary star in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. A Wolf–Rayet star and a supergiant companion of spectral type O orbit in a period of 19.56 days. The system is surrounded by a ring-shaped nebula known as a bubble nebula.
Distance from Earth: ~180,000 light years

AB7 is a binary star, consisting of one WR-star—highly evolved massive star-and a mid-age massive companion of spectral type O. These exceptional stars have very strong stellar winds: they continuously eject energetic particles—like the "solar wind" from the Sun—around 10 to 1,000 million times more intensely than our star. These powerful winds exert an enormous pressure on the surrounding interstellar material and forcefully shape those clouds into "bubbles", well visible in the photos by their blue color. AB7 is particularly remarkable: the associated huge nebula and HeII region indicate that this star is one of the, if not the, hottest WR-star known so far, with a surface temperature in excess of 120,000 degrees! Just outside this nebula, a small network of green filaments is visible—they are the remains of another supernova explosion.

Milan, Italy by Night | International Space Station

Milan, Italy by Night | International Space Station

As the world watches the 2026 Winter Olympics in Milano and Cortina d’Ampezzo, astronauts aboard the International Space Station continue capturing stunning images of cities across the globe, including Milan itself. The International Space Station is a symbol of what nations can achieve together, built and operated through decades of partnership among NASA and other space agencies around the world.

From orbit, borders fade and cooperation takes center stage—a fitting reminder as athletes from every corner of the planet come together in Italy for a celebration of unity, skill, and global spirit.

The metropolitan area of Milan (or Milano) illuminates the Italian region of Lombardy, in a pattern evocative of a patchwork quilt, in this astronaut photograph. The city of Milan proper forms a dense cluster of lights at image center left; brilliant white lights indicate the historic center of the city where the Duomo di Milano (Milan Cathedral) is located. Large dark regions to the south of Milan contain mostly agricultural fields. To the north, numerous smaller cities are interspersed with agricultural fields giving way to forested areas as one approaches the Italian Alps (not shown). Low patchy clouds diffuse the city lights, producing isolated regions in the image that appear blurred.

The Milan urban area is located within the Po Valley, a large plain bordered by the Adriatic Sea to the south and the Italian Alps to the north. Milan has the largest metropolitan area in Italy, and the fifth largest in the European Union. It is one of Europe's major transportation, industrial, and commerce hubs, and is also a global center of fashion and culture.

NASA Crew-12's SpaceX Falcon 9 Rocket & Dragon | International Space Station

NASA Crew-12's SpaceX Falcon 9 Rocket & Dragon | International Space Station


NASA’s SpaceX Crew-12 Mission will see four people embark on a long-duration science expedition to the International Space Station. Jessica Meir and Jack Hathaway are the NASA astronauts supporting the mission. Meir will serve as commander and Hathaway will serve as the Crew-12 pilot. The crew also has two mission specialists, European Space Agency astronaut Sophie Adenot of France and Roscosmos cosmonaut Andrey Fedyaev of Russia. 

NASA’s SpaceX Crew-12 mission has been cleared to proceed with launch preparations following a Flight Readiness Review with NASA, SpaceX, and the agency’s international partners. Liftoff of Crew-12 aboard a SpaceX Falcon 9 rocket and Dragon spacecraft remains on track for no earlier than 6:01 a.m. EST on Wednesday, Feb. 11, 2026, from Space Launch Complex 40 at Cape Canaveral.

Already in quarantine, the Crew-12 crew members arrived at NASA’s Kennedy Space Center in Florida on Friday night to begin their final preparations ahead of launch. On Saturday, Feb. 7, SpaceX will roll the rocket and spacecraft to pad 40 where it will be raised into its launch position. The crew also will take questions during a virtual news conference from Astronaut Crew Quarters at 11 a.m. on Sunday, Feb. 8, available on NASA Kennedy’s YouTube channel. This will be the crew’s final media opportunity before launch. The four crew will perform a full rehearsal of launch day activities on the morning of Monday, Feb. 9, including putting on their spacesuits, going to their launch pad, and strapping into the Dragon spacecraft.

Mission managers from NASA and SpaceX also will discuss the preparations and launch status at 11 a.m. on Feb. 9 from Kennedy.

As part of the agency’s Flight Readiness Review, NASA evaluated the findings from SpaceX’s review of a Starlink mission where a Falcon 9 second stage experienced an issue during preparations for its deorbit burn. NASA and SpaceX have determined, since the Falcon 9 second stage flies a different deorbit profile for NASA’s crewed missions, there is no increased risk to crew safety during ascent. The agency and SpaceX are “go” for Crew-12 to launch to the International Space Station.

Crew-12 is the 12th crew rotation mission of SpaceX’s human space transportation system and its 13th flight with astronauts for NASA, including the Demo-2 test flight, to the space station through the agency’s Commercial Crew Program.

They have trained for their mission across the world, including NASA’s Johnson Space Center in Houston, Texas, SpaceX facilities in Hawthorne, California, and international training locations. Once their Dragon spacecraft arrives at the space station, they will spend their eight month long duration mission conducting scientific experiments and maintaining the orbiting lab.

Aurora over State of New York

Aurora over State of New York

Astrophotographer: "The last G4 substorm caused by the speeding bullet CME occurred shortly after sunset on the 21st. It was brief but quite intense and it built up rapidly. At 42N, the pink columns reached about 70 degrees high at times. A magical moment."

New York, also called New York State, is a state located in the northeastern United States. Bordering New England to its east, Canada to the north, and Pennsylvania and New Jersey to the south, its territory extends into both the Atlantic Ocean and the Great Lakes. New York is the fourth-most populous state in the United States.

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.

The Stadium will host the opening ceremony of the 2026 Winter Olympics, also known as the Milano Cortina Games, taking place simultaneously in regions and venues across northern Italy.

With the 2026 Winter Olympics officially opening on Friday, February 6, 2026, the Copernicus Sentinel-2 mission and other Earth observation satellites bring us striking views of northern Italy, highlighting several key Olympic venues.

Also known as the Milano Cortina Games, this year’s Olympics are geographically widespread, with events taking place simultaneously in regions and venues across northern Italy, including Milan, Bormio, Livigno, Anterselva, Cortina d’Ampezzo, Predazzo, Tesero and Verona.

The upper part of this cloud-free image is dominated by the mountains and valleys of the Alps, where most venues are situated.

To the northeast lies Cortina d’Ampezzo, the town that lends its name to this year’s Games. Often called the Pearl of the Dolomites, Cortina sits at the heart of these dramatic mountains—also a UNESCO world heritage site. A renowned winter sports resort, Cortina also hosted the 1956 Winter Olympics.

This year’s opening ceremony will be held at the San Siro Stadium in Milan, visible as a grey area nestling below the Alps in the lower left corner of the image. Milan is Italy’s second-most populous city after Rome, with its wider metropolitan area extending across Lombardy and eastern Piedmont.

Further east, the deep blue waters of Lake Garda stand out in the center of the image. Covering 370 square kilometers, Garda is the largest lake in Italy and the third largest in the Alpine region.

East of Lake Garda is the city of Verona, hosting the closing ceremony, bringing the two weeks of sporting events to an end. Verona’s historic urban architecture, such as the renowned Arena—its circular Roman amphitheatre—have earned it UNESCO World Heritage Site status. On March 6, the Arena will also host the opening ceremony of the Paralympic Winter Games, marking the 50th anniversary of the first Paralympic Winter Games.

Moving further to the east, in the bottom right, is another famous Italian landmark: the turquoise colors of the crescent-shaped Venetian lagoon and the islands that make up the floating city of Venice along the Adriatic coast.

Close-up: Galaxy NGC 1275 in The Perseus Cluster | Sloan Digital Sky Survey

Close-up: Galaxy NGC 1275 in The Perseus Cluster | Sloan Digital Sky Survey

This large mosaic from the Sloan Digital Sky Survey telescope plunges us into the heart of the gigantic Perseus cluster. Located at 250 million light-years from Earth, it is, in fact, a neighboring cluster of galaxies where its effervescence can be observed in detail.

The gas found between the galaxies reaches 60 million degrees Celsius and emits a wealth of x-ray light caught by NASA's Chandra space telescope (in blue). The giant elliptical galaxy NGC 1275 rests in the middle of the cluster, its spectacular filaments are imaged by the NASA/European Space Agency Hubble Space Telescope.

This galaxy harbors an active supermassive black hole that powers strong jets of particles into the cluster. Equipped with new receivers, the National Radio Astronomy Observatory (NRAO) Karl G. Jansky Very Large Array as allowed us to image the radio emission of these particles with an unprecedented level of detail (in pink), revealing a multitude of mysterious and complex structures.

Galaxy NGC 1275 in The Perseus Cluster: Wide-field view

Galaxy NGC 1275 in The Perseus Cluster: Wide-field view

Active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission. NGC 1275 accretes matter as entire galaxies fall into it, ultimately feeding a supermassive black hole at the galaxy's core. Narrowband image data used in this sharp telescopic image highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long. The filaments persist in NGC 1275, even though the turmoil of galactic collisions should destroy them.

What keeps the filaments together? 
Observations indicate that the structures, pushed out from the galaxy's center by the black hole's activity, are held together by magnetic fields. Also known as Perseus A, NGC 1275 itself spans over 100,000 light years and lies about 230 million light years away.

Comet C/2024 E1 (Wierzchos): View from Namibia

Comet C/2024 E1 (Wierzchos): View from Namibia

C/2024 E1 (Wierzchoś) is a hyperbolic Oort cloud comet, discovered on March 3, 2024, by Polish astronomer Kacper Wierzchoś. It reached perihelion on January 20, 2026, with apparent magnitude of around +6.5, visible in larger binoculars. It has a highly eccentric orbit with an inbound orbital period of millions of years and is expected to eventually be ejected from the Solar System. Cometary emission activity for C/2024 E1 has been driven by carbon dioxide (CO2). It crossed the celestial equator on November 17, 2025. As of December 7, 2025, the comet was about apparent magnitude 11 and less than 20 degrees from the Sun.

Namibia, officially the Republic of Namibia, is a country in southern Africa. Its borders include the Atlantic Ocean to the west, Angola and Zambia to the north, Botswana to the east and South Africa to the south; in the northeast, approximating a quadripoint, Zimbabwe lies less than 200 meters (660 feet) away along the Zambezi River near Kazungula, Zambia.

Glowing Shells of Gas: Planetary Nebula ESO 456-67 in Sagittarius | Hubble

Glowing Shells of Gas: Planetary Nebula ESO 456-67 in Sagittarius | Hubble


It may look like something from The Lord of the Rings, but this fiery swirl is actually a planetary nebula known as ESO 456-67. Set against a backdrop of bright stars, the rust-colored object lies in the constellation of Sagittarius (The Archer), in the southern sky.

Despite the name, these ethereal objects have nothing at all to do with planets; this misnomer came about over a century ago, when the first astronomers to observe them only had small, poor-quality telescopes. Through these, the nebulae looked small, compact, and planet-like—and so were labelled as such.

When a star like the Sun approaches the end of its life, it flings material out into space. Planetary nebulae are the intricate, glowing shells of dust and gas pushed outwards from such a star. At their centres lie the remnants of the original stars themselves—small, dense white dwarf stars.

In this image of ESO 456-67, it is possible to see the various layers of material expelled by the central star. Each appears in a different hue—red, orange, yellow, and green-tinted bands of gas are visible, with clear patches of space at the heart of the nebula. It is not fully understood how planetary nebulae form such a wide variety of shapes and structures. They can appear to be spherical,  elliptical, and others shoot material in waves from their polar regions. The can look like hourglasses or figures of eight, and others resemble large, messy stellar explosions—to name but a few.

Sun Releases Another Strong Solar Flare | NASA’s Solar Dynamics Observatory

The Sun emitted a strong solar flare, peaking at 7:13 a.m. Eastern Time on Wednesday, Feb. 4, 2026. This image was captured by NASA’s Solar Dynamics Observatory (SDO). 
In this composite image are all six X-class flares layered onto the Sun at once. The images come from NASA's Solar Dynamics Observatory (SDO). It observes the Sun in multiple wavelengths, using filters to reveal distinct traits.

The Sun emitted six X-class solar flares so far in February 2026, including a strong solar flare, peaking at 7:13 a.m. ET on February 4. NASA’s Solar Dynamics Observatory, watching the Sun constantly, captured an image of the event. This flare is classified as an X4.2 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

NASA’s Solar Dynamics Observatory captured this image of a solar flare (first picture)—seen as the bright flash toward the upper middle—on Feb. 4, 2026. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares that is colorized in blue and red.

Image Description: The Sun against a black background. The Sun is colorized primarily in blue, with brighter purple areas scattered across the star showing higher activity areas. Toward the upper center of the star, there is a bright flash in white and red. It looks like an X—the solar flare.

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.

Chunks of ice, appearing light blue in this false-color image, line the western shore of Manhattan in the Hudson River. Smaller rivers and lakes in the scene also appear frozen or partially frozen. The ground is snow-covered, and tall buildings cast long, dark shadows.

The New York metropolitan area was showing the effects of a prolonged cold spell in late January 2026. During a stretch of frigid weather, ice choked the Hudson River along Manhattan’s western shore.

The Operational Land Imager (OLI) on Landsat 8 captured this image of the wintry landscape around midday on January 28. The image is false-color (bands 5-4-3) to distinguish ice (light blue) from open water and snow. Vegetation appears red. Ice is abundant in the Hudson River and visible in smaller amounts in the East River, the Jacqueline Kennedy Onassis Reservoir in Central Park, and waterways in New Jersey.

Temperatures in New York City dropped below freezing on January 24 and stayed there for over a week. The high on January 28, the date of the image, was 23 degrees Fahrenheit (minus 5 degrees Celsius). Low temperatures and harsh wind chills gripped much of eastern North America over this period amid a surge of Arctic air.

Much of the ice in the image likely floated there from farther upriver, where tidal currents are weaker and salinity is lower. These conditions allow water to freeze sooner and at higher temperatures than the faster-flowing, brackish water near the river’s mouth, shown here. A complete freeze of the Hudson around Manhattan is unlikely, experts say, although it did occur back in 1888. Still, the ice buildup was substantial enough for NYC Ferry to suspend services for several days.

Iced-up rivers can have other implications, from flooding and infrastructure damage to changes in hydrologic processes that affect water quality and aquatic habitats.

Scientists, government agencies, and emergency responders are increasingly turning to remote sensing technologies such as synthetic aperture radar and hyperspectral imaging to track river ice. Improved monitoring can aid in water resource management and mitigate ice’s effects on infrastructure and ecosystems.

In addition to the river ice, other signs of winter were visible across New York. A fresh layer of snow coated the landscape following a winter storm, in which a weather station in Central Park recorded nearly 12 inches (30 centimeters) of accumulation on January 25. And the low angle of the midwinter Sun caused the tall buildings in Midtown and Lower Manhattan to cast long shadows.

In a neighboring borough on February 2, a shorter shadow was cast—this one by the weather-prognosticating groundhog known as Staten Island Chuck. Folklore holds that the sighting signals six more weeks of winter. When compared with data from the National Oceanic and Atmospheric Administration's National Centers for Environmental Information, the New York rodent was deemed the most accurate of his peer weather “forecasters.” This year, Chuck might be right, at least in the near term: the National Weather Service forecast called for below-average temperatures to persist, with Arctic air returning to the city by the weekend.

New York, often called New York City (NYC), is the most populous city in the United States. It is located at the southern tip of New York State on New York Harbor, one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with its respective county. It is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York, also called New York State, is a state located in the northeastern United States. Bordering New England to its east, Canada to the north, and Pennsylvania and New Jersey to the south, its territory extends into both the Atlantic Ocean and the Great Lakes.
