International Day of Women and Girls in Science | UN Office for Outer Space Affairs

International Day of Women and Girls in Science | UN Office for Outer Space Affairs

February 11 is the International Day of Women and Girls in Science! Today, we celebrate the important contributions of women to the Science, Technology, Engineering and Math (STEM) disciplines. 

The world needs science, and science needs women. 👩‍🔬🧪 Yet, they remain under-represented and struggle to receive recognition for their achievements.

UNOOSA Director Aarti Holla-Maini explains: “When 50% of the world’s population are women, gender equality is not only the right thing to do, but it is also the smart thing to do.”  The mission is far from over but UNOOSA has solutions…

UNOOSA website: https://www.unoosa.org

Increasing female representation in space is not just about fairness, it is key to unlocking humanity’s full potential and ensuring that our presence in space reflects our society here on Earth.

UNOOSA’s Space4Women initiative empowers women across the global space sector and inspires the next generation of female space leaders. Our Gender Mainstreaming Toolkit, funded by the Canadian Space Agency, provides actionable solutions. Together with our partners at the Kenya Space Agency, we are also developing a new toolkit to break down barriers to STEM education for women and girls in marginalized communities.

The Spider (IC 417) and The Fly (NGC 1931) Nebulae in Auriga

The Spider (IC 417) and The Fly (NGC 1931) Nebulae in Auriga

Will the spider ever catch the fly? Not if both are large emission nebulas toward the constellation of the Charioteer (Auriga). The spider-shaped gas cloud in the image center is actually an emission nebula labelled IC 417, while the smaller fly-shaped cloud on the left is dubbed NGC 1931 and is both an emission nebula and a reflection nebula. About 10,000 light-years distant, these nebulas harbor young star clusters. For scale, the more compact NGC 1931 (Fly) is about ten light-years across. The featured deep image, captured over twenty hours during late January in Berkshire, United Kingdom, also shows more diffuse and red-glowing interstellar gas and dust.

Image Description: A star field has a red diffuse glow on the right-hand side. Distinct nebulas appear in the center and on the lower left.

Dwarf Galaxy Leo P | James Webb Space Telescope

Dwarf Galaxy Leo P | James Webb Space Telescope


This image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope shows a portion of the Leo P dwarf galaxy (stars at lower right represented in blue). Leo P is a star-forming galaxy located about 5 million light-years away in the constellation Leo. A team of scientists collected data from about 15,000 stars in Leo P to deduce its star formation history. They determined that it went through three phases: an initial burst of star formation, a “pause” that lasted several billion years, and then a new round of star formation that is still continuing.

The image from Webb’s Near-Infrared Camera (NIRCam) combines infrared light at wavelengths of 0.9 microns (represented in blue), 1.5 microns (green), and 2.77 microns (red). The stars in Leo P appear blue in comparison to the background galaxies for several reasons. Young, massive stars that are common in star-forming galaxies are predominantly blue. Leo P also is extremely lacking in elements heavier than hydrogen and helium, and the resulting “metal-poor” stars tend to be bluer than Sun-like stars. A bubble-like structure at bottom center is a region of ionized hydrogen surrounding a hot, massive O-type star.

Shenzhou-18 Crew Shares Gripping Spacewalk Moments | China Space Station

Shenzhou-18 Crew Shares Gripping Spacewalk Moments | China Space Station

From their time in space between April 25 to November 4, 2024, Shenzhou-18 crew members have shared gripping moments of confronting abyssal darkness during their spacewalks in an interview. While conducting an 8.5-hour extravehicular activity (EVA) on May 28, 2024, astronauts Ye Guangfu, Li Cong, and Li Guangsu successfully installed space debris protection devices, among other tasks.

Ye and Li Guangsu were assigned to the spacewalk and safely returned to the station's Wentian lab module after the venture. This EVA marked the 15th spacewalk by Chinese astronauts during the space station's application and development phase. It was the first spacewalk for Li Guangsu, who operated the station's robotic arms during the EVA.

"I still remember the fear I felt in the shadowed area. On the sunlit side, it was fine—I could see the space station and the Earth, which made me feel reassured. But once into the shadow zone, if I didn't turn on the light, all I could see below me was an abyss of blackness. Even though my safety tether was securely attached to the handrail on the space station, I didn't dare let go of my hand. I knew logically that even if I released my grip, I wouldn't drift away because my tether was still connected to the space station—but the overwhelming darkness made me reluctant to take my hand off the handrail," said Li Guangsu.

Although this was Ye's second spacewalk, following his first on the Shenzhou-13 mission, he admitted that the darkness still kept him on high alert every second.

"I felt as if I were about to be swallowed by the darkness. At one point, I accidentally moved my body, and for a moment, I lost my sense of connection with the robotic arm, I was startled. Why? Because beneath me was nothing but an endless black void. In that moment, a wave of nervousness hit me, and I felt my hair stand on end. What was happening? No matter how drowsy I had been, I was instantly wide awake, carefully adjusting my position to ensure I was still on the robotic arm. Only then did I feel at ease. 'Alright, everything is fine,' I told myself, and I continued with my task," said Ye.

Revealing a Filament from The Cosmic Web | European Southern Observatory

Revealing a Filament from The Cosmic Web | European Southern Observatory


This image shows countless stars and galaxies in the background. Two galaxies are shown at the forefront, each with a bright nucleus. This indicates the presence of a quasar. The galaxies appear like large nebulae without a concrete shape. The content of the galaxies extend beyond their immediate shape, forming a bridge that connects the two galaxies. This bridge is a cosmic filament.

From decades of astronomical observations, scientists know that most galaxies contain massive black holes at their centers. The gas and dust falling into these black holes liberates an enormous amount of energy as a result of friction, forming luminous galactic cores, called quasars, that expel jets of energetic matter.

Is there an invisible web of dark matter surrounding us? Its influence can be observed across the cosmos, but the web remains unseen . . . for the most part. This picture shows the clearest image yet of a filament from this cosmic web. The filament was imaged with the European Southern Observatory’s Very Large Telescope (VLT), and is shown here in purple overlaid on a background image from the NASA/European Space Agency Hubble Space Telescope. Made of gas clumped together by the influence of dark matter, the filament stretches out for 3 million light-years, connecting two distant galaxies in the early Universe.

Around 85% of all matter in the Universe is actually dark matter. Dark matter is invisible, but the gas around it is not. This gas glows extremely faintly though, making these structures very difficult to observe. However, after about 150 hours of observations, a team of astronomers led by Davide Tornotti, a PhD student at the University of Milano-Bicocca in Italy, managed to take this sharp image of a cosmic filament. This was possible thanks to the exceptional sensitivity of the MUSE instrument at the VLT. It has become a workhorse instrument for imaging the cosmic web. 

The light from this filament took 11 billion years to reach us, and it shows exactly what theory predicted. In the early Universe, filaments of dark matter could have created a large web that entangled gas through their gravitational pull. Once gas accumulated at the intersection between filaments, it would have provided the fuel necessary to form galaxies. As we observe more of these mysterious filaments, what else will we find trapped within this dark web?

NOAA Weather Satellites Track Atmospheric Rivers on U.S. West Coast

NOAA Weather Satellites Track Atmospheric Rivers on U.S. West Coast

Since Jan. 31, 2025, National Oceanic and Atmospheric Administration (NOAA) satellites have been closely monitoring a series of strong atmospheric rivers bringing heavy rain and mountain snow from central California to the Pacific Northwest, the Sierra, southern Cascades, and northern Rocky mountains. 

Atmospheric rivers are long, narrow bands of concentrated water vapor that transport moisture from warm tropical oceans to higher latitudes. In these regions, heat from the sun causes large amounts of water to evaporate into the atmosphere. When this humid air meets the mountains along the West Coast, the winds blow uphill, and the air cools, condenses, and precipitates, forming a torrent of rain and wind. 

These systems vary in size and strength, but on average, they carry as much water vapor as the Mississippi River discharges at its mouth—and can even transport up to 15 times that amount. When they make landfall, they unleash heavy rain or snow, accounting for roughly 30 to 50 percent of annual precipitation in the West Coast states.

NOAA and its partners utilize advanced satellite observations to study atmospheric rivers. Satellite data, combined with land-based observations, helps refine forecast models, improving predictions of atmospheric river intensity and duration to support water resource management and public safety.

Bright Einstein Ring Detected: Galaxy NGC 6505 in Draco | Euclid Space Telescope

Bright Einstein Ring Detected: Galaxy NGC 6505 in Draco | Euclid Space Telescope

This wide field shows the extended stellar halo of galaxy NGC 6505 and showcases the Einstein ring, surrounded by colorful foreground stars and background galaxies.

Close-up of the Einstein ring around galaxy NGC 6505

The ring of light surrounding the center of the galaxy NGC 6505, captured by the European Space Agency's Euclid telescope, is a stunning example of an Einstein ring. NGC 6505 is acting as a gravitational lens, bending light from a galaxy far behind it. The almost perfect alignment of NGC 6505 and the background galaxy has bent and magnified the light from the background galaxy into a spectacular ring. This rare phenomenon was first theorized to exist by Einstein in his general theory of relativity.

The wide field in the first image shows the extended stellar halo of NGC 6505 and showcases the Einstein ring, surrounded by colorful foreground stars and background galaxies.

Image 1 Description: A sea of colorful stars and galaxies appear to swim in the vast blackness of space around a hazy halo at centre stage. In the middle of the image, the fuzzy-looking bulb of light in a warm shade of yellow extends around a small bright spot, nestled within a thin light circle that appears to be drawn closely around it. As we follow the central halo’s rim outwards, its brightness dims and blends smoothly into its surroundings. Here, extended discs of shades ranging from a warm purple to golden yellow, and piercing dots of light with sharp diffraction spikes are spread evenly across the image.

In the second image, we see a close-up view of the center of the NGC 6505 galaxy with the bright Einstein ring around its nucleus, captured by the European Space Agency's Euclid space telescope.

The Einstein ring is formed by gravitational lensing, with the mass of galaxy NGC 6505 bending and magnifying the light from a more distant galaxy into a ring. NGC 6505 is a well-known galaxy only around 590 million light-years from Earth, and Euclid’s discovery of a spectacular Einstein ring here was unexpected.

Image 2 Description: A thin ring of a perfect circular shape and a piercingly bright white disc in its middle are the protagonists of this image. They stand out against a uniformly coloured background of a hazy dark grey. The ring appears as if it was a faint brush stroke, where at four evenly spaced spots more pressure was applied on the brush. These stand out in the ring as four brighter and thicker spots. The white disc within the ring gives the impression of a gaping hole in the image, through its stark contrast to the dark background.

The Tarantula Nebula: A Cosmic Cloudscape in Dorado | Hubble Space Telescope

The Tarantula Nebula: A Cosmic Cloudscape in Dorado | Hubble Space Telescope


The Universe is a dusty place, as this NASA/European Space Agency Hubble Space Telescope picture shows. Featured in this image are swirling clouds of gas and dust near the Tarantula Nebula in the Large Magellanic Cloud (LMC). About 160,000 light-years away in the constellations Dorado and Mensa, the Large Magellanic Cloud is one of the nearest galaxies to the Milky Way. The Tarantula Nebula is the most productive star-forming region in the nearby Universe, home to the most massive stars known.

The colorful gas clouds of this nebula are crossed by wispy tendrils and dark clumps of dust. This dust is different from ordinary household dust that can be made of bits of soil, skin cells, hair and even plastic. Cosmic dust tends to be made of carbon or of molecules called silicates that contain silicon and oxygen. The data used to create this image were collected as part of an observing program aiming to characterize the properties of cosmic dust in the Large Magellanic Cloud and other nearby galaxies.

Dust plays several important roles in the Universe. Even though individual dust grains are incredibly tiny, far smaller than the width of a single human hair, dust grains in discs around young stars clump together to form larger grains and eventually planets. Dust also helps cool clouds of gas so that they can condense into new stars. Dust even plays a role in making new molecules in interstellar space, providing a venue for individual atoms to find each other and bond together in the vastness of space.

Image Description: A portion of a nebula, made of variously-colored layers of dust clouds. One upper layer is dark reddish dust. This is dense and obscures light, in places so dense that it appears black. A middle layer is pale clouds that are thick like curling wisps of smoke. They form a broad bow across the center of the image. Many small, bright stars lie throughout the nebula, colored blue, purple or red depending on the depth.

Close-up view: Protoplanetary Disc in Taurus Molecular Cloud | LDN 1551 | Webb

Close-up view: Protoplanetary Disc in Taurus Molecular Cloud | LDN 1551 | Webb


This new NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope picture presents HH 30 in unprecedented resolution. This target is an edge-on protoplanetary disc that is surrounded by jets and a disc wind. It is located in the dark cloud LDN 1551 in the Taurus Molecular Cloud at a distance of 477 light years.

Herbig-Haro objects are small nebulae found in star formation regions, marking the locations where gas outflowing from young stars is heated into luminescence by shockwaves. HH 30 is an example of where this outflowing gas takes the form of a narrow jet. The source star is located on one end of the jet, hidden behind an edge-on protoplanetary disc that the star is illuminating.

HH 30 is of particular interest to astronomers. In fact, the HH 30 disc is considered the prototype of an edge-on disc, thanks to its early discovery with the NASA/European Space Agency Hubble Space Telescope. Discs seen from this view are a unique laboratory to study the settling and drift of dust grains.

An international team of astronomers have used Webb to investigate the target in unprecedented detail. By combining Webb’s observations with those from the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA), the team was able to study the multiwavelength disc appearance of the system.

The long-wavelength data from ALMA trace the location of millimeter-sized dust grains. These are found in a narrow region in the central plane of the disc. The shorter-wavelength infrared data from Webb reveal the distribution of smaller dust grains. These grains are only one millionth of a meter across—about the size of a single bacterium. While the large dust grains are concentrated in the densest parts of the disc, the small grains are much more widespread.

These Webb observations were taken as part of the Webb GO program #2562 (PI F. Ménard, K. Stapelfeldt). It aims to understand how dust evolves in edge-on discs like HH 30. Combined with the keen radio-wavelength eyes of ALMA, these observations show that large dust grains must migrate within the disc and settle in a thin layer. The creation of a narrow, dense layer of dust is an important stage in the process of planet formation. In this dense region, dust grains clump together to form pebbles and eventually planets themselves.

In addition to the behavior of dust grains, the Webb, Hubble, and ALMA images reveal several distinct structures that are nested within one another. Emerging at a 90-degree angle from the narrow central disc is a high-velocity jet of gas. The narrow jet is surrounded by a wider, cone-shaped outflow. Enclosing the conical outflow is a wide nebula that reflects the light from the young star that is embedded within the disc. Together, these data reveal HH 30 to be a dynamic place, where tiny dust grains and massive jets alike play a role in the formation of new planets.

Image Description: A close-in image of a protoplanetary disc around a newly formed star. Many wavelengths of light are combined and represented by separate and various colors. A dark line across the center is the disc, corresponding to the densest parts of the disc, made of opaque dust: the star is hidden in here and creates a strong glow in the center. A band going straight up is a jet, while other outflows above and below the disc, and a tail coming off to one side.

Shenzhou-19 Crew Marks 100 Days in Orbit | China Space Station

Shenzhou-19 Crew Marks 100 Days in Orbit | China Space Station

China's Shenzhou-19 crew has spent 100 days aboard the Tiangong Space Station since the launch over three months ago, successfully carrying out mission assignments and celebrating the traditional Chinese Spring Festival in orbit.

The Shenzhou-19 crew was launched into space on October 30, 2024, for a six-month mission, prior to the end of the previous Shenzhou 18 mission. Saturday, February 8, 2025, marked the 100th day in space for the three astronauts—Cai Xuzhe, Song Lingdong, and Wang Haoze.

During the 100 days, the Shenzhou-19 crew members carried out their duties efficiently aboard the Tiangong Space Station, maintaining a steady workflow and ensuring mission objectives were met as planned.

Last week and earlier, the three astronauts celebrated the Spring Festival, or the Chinese New Year holiday, in orbit, marking the fourth Spring Festival celebrated by Chinese space station crew.

The astronauts pasted Spring Festival couplets, hung the Chinese characters of Fu (good fortune) and shared a New Year's Eve family reunion dinner on January 28 to celebrate the festival in space.

The crew donned festive outfits and extended their new year wishes to Chinese people, and called their families and friends via video link on this festive occasion.

Over the past 100 days, they conducted daily duties, such as station management and various space science experiments efficiently.

The astronauts also completed blood sample collection, centrifugation, packaging and freezing.

The samples will be analyzed by ground researchers to study the changes in bone-related physiological systems during long-term spaceflight and the effects of the space environment on gene expression regulation.

The crew also used the relevant equipment and software to conduct behavioral tests and fine motor control tests with the testing data intended to explore the impact of gravity on visual motion information processing and the cognitive mechanisms behind fine motor control in microgravity.

Moreover, the crew completed in-orbit emotional state assessments and evaluations on emergency decision-making ability as part of ongoing research into astronaut psychology and behavior.

As per their schedule, the crew underwent medical checks using instruments, like traditional Chinese medicine diagnostic tools and bone density meters to monitor their health, while conducting physical exercise.

SpaceX Starship Super Heavy Booster Rollout for 8th Flight Test | Starbase Texas

SpaceX Starship Super Heavy Booster Rollout for 8th Flight Test | Starbase Texas






SpaceX Starship's Super Heavy booster is seen here being moved to the launch pad at Starbase Texas in Boca ChicaThe ship and booster for Starship’s eighth flight test have been built and tested. SpaceX is going through prelaunch preparations as "we continue a rapid iterative development process to build a fully and rapidly reusable space transportation system."

SpaceX’s Starship spacecraft and Super Heavy rocket—collectively referred to as Starship—represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship is the world’s most powerful launch vehicle ever developed, capable of carrying up to 150 metric tonnes fully reusable and 250 metric tonnes expendable.

Key Starship Parameters:
Height: 123m/403ft
Diameter: 9m/29.5ft
Payload to LEO: 100–150t (fully reusable)

"Starship is essential to both SpaceX’s plans to deploy its next-generation Starship system as well as for NASA, which will use a lunar lander version of Starship for landing astronauts on the Moon during the Artemis III mission through the Human Landing System (HLS) program."
