This is a new artist’s animation of our galaxy, the Milky Way, based on data from ESA’s Gaia space telescope.
Gaia has changed our impression of the Milky Way. Even seemingly simple ideas about the nature of our galaxy’s central bar and the spiral arms have been overturned. Gaia has shown us that it has more than two spiral arms and that they are less prominent than we previously thought. In addition, Gaia has shown that its central bar is more inclined with respect to the Sun. No spacecraft can travel beyond our galaxy, so we can’t take a selfie, but Gaia is giving us the best insight yet of what our home galaxy looks like. Once all of Gaia’s observations collected over the past decade are made available in two upcoming data releases, we can expect an even sharper view of the Milky Way.

Watch Firefly Aerospace’s Blue Ghost lunar lander lift off from NASA’s Kennedy Space Center in Florida on a SpaceX Falcon 9 rocket. SpaceX and Firefly Aerospace are targeting 1:11 a.m. EST (0611 UTC) Wednesday, Jan. 15, 2025, for launch. The lander will carry 10 NASA science investigations to the Moon’s surface.
Following launch, the lander will spend approximately 45 days in transit to the Moon before landing on the lunar surface in early March 2025. The 10 NASA payloads aboard the lander aim to test and demonstrate lunar subsurface drilling technology, regolith sample collection capabilities, global navigation satellite system abilities, radiation tolerant computing, and lunar dust mitigation methods.
The results of these investigations could help further our understanding of the Moon’s environment and help prepare for future human missions to the lunar surface as part of the agency’s Moon to Mars exploration approach.

Fly over Mercury with BepiColombo for the final time during the mission’s epic expedition around the Sun. The ESA/JAXA spacecraft captured these images of the Solar System’s smallest planet on 7 and 8 January 2025, before and during its sixth encounter with Mercury. This was its final planetary flyby until it enters orbit around the planet in late 2026.
The video begins with BepiColombo’s approach to Mercury, showing images taken by onboard monitoring cameras 1 and 2 (M-CAM 1 and M-CAM 2) between 16:59 CET on 7 January and 01:45 CET on 8 January. During this time, the spacecraft moved from 106 019 to 42 513 km from Mercury’s surface. The view from M-CAM 1 is along a 15-metre-long solar array, whereas M-CAM 2 images show an antenna and boom in the foreground.
After emerging into view from behind the solar array, Mercury appears to jump to the right. Both the spacecraft and its solar arrays rotated in preparation for passing through Mercury’s cold, dark shadow.
For several hours after these first images were taken, the part of Mercury’s surface illuminated by the Sun was no longer visible from the M-CAMs. BepiColombo’s closest approach to Mercury took place in darkness at 06:58:52 CET on 8 January, when it got as close as 295 km.
Shortly after re-emerging into the intense sunlight, the spacecraft peered down onto the planet’s north pole, imaging several craters whose floors are in permanent shadow. The long shadows in this region are particularly striking on the floor of Prokofiev crater (the largest crater to the right of centre) – the central peak of that crater casts spiky shadows that exaggerate the shape of this mountain.
Next, we have a beautiful view of Mercury crossing the field of view from left to right, seen first by M-CAM 1 then by M-CAM 2 between 07:06 and 07:49 CET. These images showcase the planet’s northern plains, which were smoothed over billions of years ago when massive amounts of runny lava flowed across Mercury’s cratered surface.
The background music is The Hebrides overture, composed by Felix Mendelssohn in 1830 after being inspired by a visit to Fingal’s Cave, a sea cave created by ancient lava flows on the island of Staffa, Scotland. Similarly shaped by lava is Mercury’s Mendelssohn crater, one of the large craters visible passing from left to right above the solar array in M-CAM 1’s views, and at the very bottom of M-CAM 2’s views. The Mendelssohn crater was flooded with lava after an impact originally created it.
The end of the video lingers on the final three close-up images that the M-CAMs will ever obtain of Mercury. The cameras will continue to operate until September 2026, fulfilling their role of monitoring various parts of the spacecraft. After that point, the spacecraft module carrying the M-CAMs will separate from BepiColombo’s other two parts, ESA’s Mercury Planetary Orbiter (MPO) and JAXA’s Mercury Magnetospheric Orbiter (Mio). MPO’s much more powerful science cameras will take over from the M-CAMs, mapping Mercury over a range of colours in visible and infrared light.

Did you know the Large Magellanic Cloud, one of our galaxy’s closest neighbors, survived a dramatic collision with the Milky Way’s gaseous halo? Despite losing most of its gas, the Large Magellanic Cloud is still forming new stars—a testament to its resilience! Thanks to Hubble Space Telescope, astronomers measured the Large Magellanic Cloud’s halo for the first time, revealing incredible insights about galaxy interactions.

BepiColombo flew past Mercury for the fifth time on 1 December 2024.
During this flyby, BepiColombo gathered more data on the mysterious planet and its surroundings. Aside from taking some ‘regular’ photos of the planet and measuring particles and electromagnetic fields in the space around it, this flyby was the first time that any spacecraft imaged Mercury in mid-infrared wavelengths of light.
BepiColombo will pass much closer to Mercury’s north pole during its final flyby of Mercury on 8 January 2025, its last visit before arriving to enter orbit about the planet in November 2026.

Hot and Cold. A home-made hot air balloon gets turned into a giant floating monstrosity! Plus: dry ice, the coldest temperature possible and Phil wears a suit of blubber and gets into a tub of ice water.
At the start of this new year, close-up pictures and solar flare data that the ESA-led Solar Orbiter mission has been recording for more than three years. See and hear for yourself how the number of flares and their intensity increase, a clear sign of the Sun approaching the peak of the 11-year solar cycle.
This video combines ultraviolet images of the Sun’s outer atmosphere (the corona, yellow) taken by Solar Orbiter’s Extreme Ultraviolet Imager (EUI) instrument, with the size and locations of solar flares (blue circles) as recorded by the Spectrometer/Telescope for Imaging X-rays (STIX) instrument. The accompanying audio is a sonification based on the detected flares and the spacecraft’s distance to the Sun.
Solar Orbiter moves on an elliptical path around the Sun, making a close approach to our star every six months. We can see this in the video from the spacecraft’s perspective, with the Sun moving closer and farther over the course of each year. In the sonification, this is represented by the low background humming that loudens as the Sun gets closer and becomes quieter as it moves further away. (There are some abrupt shifts in distance visible in the video, as it skips over dates where one or both instruments were inactive or collecting a different type of data.)
The blue circles represent solar flares: bursts of high-energy radiation of which STIX detects the X-rays. Flares are sent out by the Sun when energy stored in ‘twisted’ magnetic fields (usually above sunspots) is suddenly released. The size of each circle indicates how strong the flare is, with stronger flares sending out more X-rays. We can hear the flares in the metallic clinks in the sonification, where the sharpness of the sound corresponds to how energetic the solar flare is.
Many thanks to Klaus Nielsen (DTU Space / Maple Pools) for making the sonification in this video. If you would like to hear more sonifications and music by this artist, please visit: https://linktr.ee/maplepools Solar Orbiter is a space mission of international collaboration between ESA and NASA, operated by ESA.
