The double-satellite Proba-3 is the most ambitious member yet of ESA’s Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimetre. One will block out the fiery disc of the Sun for the other, to enable prolonged observations of the Sun’s surrounding atmosphere, or ‘corona’, the source of the solar wind and space weather. Usually, the corona can only be glimpsed for a few minutes during terrestrial total solar eclipses.
Proba-3 aims to reproduce such eclipses for up to six hours at a time, in a highly elliptical orbit taking it more than 60 000 km from Earth. The two spacecraft are being launched together by India’s PSLV-XL launcher from the Satish Dhawan Space Centre.
Join us on a unique video tour of the Sun’s mesmerising surface. Thanks to its innovative instrumentation and a ‘daring’ trajectory passing close to the Sun, ESA’s Solar Orbiter spacecraft has obtained the highest-resolution full views of the Sun’s surface to date.
Watching the Sun in visible light, Solar Orbiter reveals a grainy surface and dark sunspots. On the same day, the spacecraft mapped the Sun’s magnetic field, tracked how fast and in which direction scorching hot material on the surface is moving, and snapped a hypnotising image in ultraviolet light of the Sun’s upper atmosphere, the corona. All taken on the same day, the four new images shown in this video let us peel away the Sun’s many layers.
The images were taken when Solar Orbiter was less than 74 million kilometres from the Sun; being so close meant each high-resolution image only covers a small portion of the Sun. To obtain the full-disc views showcased in the video, 25 images were stitched together like a mosaic. The Sun has a diameter of around 8000 pixels in the full mosaics, revealing an extraordinary amount of detail.

On April 8, 2024, North America’s last total solar eclipse until 2045 moved across the continent. It made landfall in Mexico, crossed the United States from Texas to Maine, and departed across Canada’s Atlantic coast.
This video offers viewers highlights of the eclipse from NASA’s live commentary. Different vantage points include the International Space Station, WB-57 aircraft, and 12 telescopes stationed across North America.
A total solar eclipse occurs when the Moon passes between the Sun and the Earth, completely blocking the face of the Sun. The sky darkens as if it were dawn or dusk.
A total solar eclipse swept across North America yesterday, blocking out the Sun momentarily with parts of the continent plunged into darkness. Geostationary satellites orbiting 36 000 km away captured images of the rare celestial event.
These images, captured by the Geostationary Operational Environmental Satellite (GOES-16), captured the moon’s shadow moving across North America from approximately 16:00 to 23:00 CEST (15:00 to 22:00 BST.)
A total solar eclipse occurs when the Moon passes between the Sun and Earth and, for a short period, blocks the face of the Sun, save for a visible ring of light, known as the Sun’s corona.
The track of the moon’s shadow across Earth’s surface, called the path of totality, spanned across the North American continent – from Mexico to the very eastern tip of Canada.
The GOES series is a collaborative development and acquisition effort between National Oceanic and Atmospheric Administration (NOAA) and NASA. The GOES-16 (GOES-East) satellite, the first of the series, provides continuous imagery and atmospheric measurements of Earth’s western hemisphere and monitors space weather.
The Copernicus Sentinel-3 mission also captured images of the eclipse with its Sea and Land Surface Temperature Radiometer (SLSTR).
The eclipse also acts as a laboratory for researching what happens to weather when the Moon’s shadow passes over. The shadow makes air temperatures drop and can cause clouds to evolve in different ways. Data from GOES, Sentinel-3 and other satellites are now being used to explore these effects.
During a solar eclipse the Earth is plunged into darkness and the Sun’s ghostly atmosphere becomes visible. Scientists travel the globe to experience total solar eclipses, which occur for just a few minutes at a time every 18 months or so. But what exactly causes solar eclipses, and how do scientists try to make their own, including with ESA’s new Proba-3 mission?
Timestaps of the video: 00:00 – 00:32 – Intro 00:33 – 01:45 – How do solar eclipses happen? 01:46 – 02:45 – How do we know anything about the solar corona given that eclipses occur so rarely? 02:46 – 04:00 – How can we create a perfect artificial solar eclipse in space?

A solar eruption detected simultaneously at Earth, the Moon and Mars emphasises the need to prepare human exploration missions for the dangers of space radiation.
This sequence was taken by Solar Orbiter’s Extreme Ultraviolet Imager using the Full Sun Imager telescope, and shows the Sun at a wavelength of 17 nanometers. This wavelength is emitted by gas in the Sun’s atmosphere with a temperature of around one million degrees. The colour on this image has been artificially added because the original wavelength detected by the instrument is invisible to the human eye.

Solar Orbiter has made the first ever remote sensing observation consistent with a magnetic phenomenon called a solar switchback – sudden and large deflections of the solar wind’s magnetic field. The new observation provides a full view of the structure, in this case confirming it has an S-shaped character, as predicted. Furthermore, the global perspective provided by the Solar Orbiter data indicates that these rapidly changing magnetic fields can have their origin near the surface of the Sun.

To prepare Europe for future decision making on Space-Based Solar Power, ESA has proposed a preparatory programme for Europe, initially named SOLARIS, for the upcoming ESA Council at Ministerial Level in November 2022.
Space-based solar power is a potential source of clean, affordable, continuous, abundant and secure energy. This basic concept has been given fresh urgency by the need for new sources of clean and secure energy to aid Europe’s transition to a Net Zero carbon world by 2050. If Europe wants to benefit from this game-changing capability then we need to start investing now.

ESA’s EarthCARE satellite mission will soon be launched to answer some critical scientific questions related to the role that clouds and aerosols play in reflecting incident solar radiation back out to space and trapping infrared radiation emitted from Earth’s surface. As engineers are preparing EarthCARE for its life in orbit, the satellite is being put through its paces at ESA testing facilities in the Netherlands – the largest satellite test facility in Europe, equipped to simulate every aspect of the space environment.
One of the first tests involved the deployment of the satellite’s 11 metre solar wing from its folded stowed configuration, which allows it to fit in the rocket fairing, to its fully deployed configuration as it will be in orbit around Earth.
This timelapse video shows this deployment test from various angles.

Solar Orbiter is a space mission of international collaboration between ESA and @NASA.
Solar Orbiter’s closest approach to the Sun, known as perihelion, took place on 26 March. The spacecraft was inside the orbit of Mercury, at about one-third the distance from the Sun to the Earth, and its heatshield was reaching around 500°C. But it dissipated that heat with its innovative technology to keep the spacecraft safe and functioning.
Installing new solar arrays for the space station, updating launch and landing dates for Commercial Crew, and NASA’s new deputy administrator is confirmed … a few of the stories to tell you about – This Week at NASA!
ESA’s Solar Orbiter spacecraft has sent back its first images of the Sun. At 77 million kilometres from the surface, this is the closest a camera has ever flown to our nearest star. The pictures reveal features on the Sun’s exterior that have never been seen in detail before.
Launched on 10 February 2020, the spacecraft completed its commissioning phase and first close-approach to the Sun in mid-June. Since then, science teams have been processing and examining this early data.
The spacecraft is currently in its cruise phase, on its way to Venus, but will eventually get even closer to the Sun.

The first images from ESA’s Solar Orbiter, captured around the spacecraft’s first close pass of the Sun, some 77 million kilometres from its surface, are already exceeding expectations revealing interesting new phenomena on our parent star.
This animation shows a series of close-up views captured by the Extreme Ultraviolet Imager (EUI) at wavelengths of 17 nanometers, showing the upper atmosphere of the Sun, or corona, with a temperature of around 1 million degrees.
These images reveal a multitude of small flaring loops, erupting bright spots and dark, moving fibrils. A ubiquitous feature of the solar surface, uncovered for the first time by these images, have been called ‘campfires’. They are omnipresent minuature eruptions that could be contributing to the high temperatures of the solar corona and the origin of the solar wind.
Captured on 30 May 2020, when Solar Orbiter was roughly halfway between the Earth and the Sun, these are the closest views of the Sun ever taken, allowing EUI to see features in the solar corona of only 400 km across. As the mission continues, Solar Orbiter will go closer to the Sun and this will increase the instrument’s resolving power by a factor of two at closest approach.
The colour on this image has been artificially added because the original wavelength detected by the instrument is invisible to the human eye.
The circle in the lower left corner indicates the size of Earth for scale.
The extended grey shape visible at times moving across the field (00:00-00:25; 01:00-01:28; 01:50-02:00; 02:52-03:27) is not a solar feature but is caused by a sensor artefact.

The first images from ESA’s Solar Orbiter are already exceeding expectations and revealing interesting new phenomena on the Sun.
This animation combines a series of views captured with several remote-sensing instruments on Solar Orbiter between 30 May and 21 June 2020, when the spacecraft was roughly halfway between the Earth and the Sun ¬– closer to the Sun than any other solar telescope has ever been before.
The red and yellow images were taken with the Extreme Ultraviolet Imager (EUI) in the extreme ultraviolet region of the electromagnetic spectrum, at wavelengths of 30 and 17 nanometers, respectively.
The close-up views by EUI show the upper atmosphere of the Sun, or corona, with a temperature of around 1 million degrees. With the power to see features in the solar corona of only 400 km across, these images reveal a multitude of small flaring loops, erupting bright spots and dark, moving fibrils. A ubiquitous feature of the solar surface, uncovered for the first time by these images, have been called ‘campfires’. They are omnipresent minuature eruptions that could be contributing to the high temperatures of the solar corona and the origin of the solar wind.
The EUI images are followed by three views based on data from the Polarimetric and Helioseismic Imager (PHI) instrument. The blue and red view is a ‘tachogram’ of the Sun, showing the line of sight velocity of the Sun, with the blue side turning to us and the red side turning away. The following view is a magnetogram, or a map of magnetic propertied for the whole Sun, featuring a large magnetically active region in the lower right-hand quadrant of the Sun. The yellow-orange view is a visible light image and represents what we would see with the naked eye: there are no sunspots visible because the Sun is displaying only low levels of magnetic activity at the moment.
On larger scales, the Metis coronograph blocks out the dazzling light from the solar surface, bringing the fainter corona into view. Metis observes the corona simultaneously in visible light (shown in green) and ultraviolet light (shown in red) for the first time with unprecedented temporal coverage and spatial resolution. These images reveal the two bright equatorial streamers and fainter polar regions that are characteristic of the solar corona during times of minimal magnetic activity.
On even grander scales, the Heliospheric Imager (SoloHI) telescope takes images of the solar wind – the stream of charged particles constantly released by the Sun into outer space – by capturing the light scattered by electrons in the wind. The first-light image from SoloHI is shown at the end, as a mosaic of four separate images from the instrument’s four separate detectors. In this view, the Sun is located to the right of the frame, and its light is blocked by a series of baffles; the last baffle is in the field of view on the right-hand side and is illuminated by reflections from the solar array. The partial ellipse visible on the right is the zodiacal light, created by sunlight reflecting off the dust particles that are orbiting the Sun. The signal from the solar wind outflow is faint compared to the much brighter zodiacal light signal, but the SoloHI team has developed techniques to reveal it. Planet Mercury is also visible as a small bright dot near the lower edge of the upper left tile.

ESA’s Solar Orbiter is getting ready for its launch on an Atlas V rocket provided by NASA and operated by United Launch Alliance from Cape Canaveral, Florida.
Once in space, and over the course of several years, the spacecraft will repeatedly use the gravity of Venus and Earth to raise its orbit above the poles of the Sun, providing new perspectives on our star, including the first images of the Sun’s polar regions.
All these operations will be controlled from the European Space Operations Centre (ESOC), Germany, where a dedicated team is currently working on simulations of the first moments in orbit, after separation from the launcher, but also all the delicate manoeuvres of the journey that will make Solar Orbiter mission possible.

The Solar Orbiter spacecraft is undergoing important pre-launch tests at the IABG National Space Centre in Ottobrunn, Germany, ahead of its launch, scheduled for February 2020.
The mission will study the Sun, but first the spacecraft must pass vibration, acoustic and shock tests. This will ensure the spacecraft can withstand the stresses of lift off and the extreme environments it will encounter while in orbit around the Sun – from the coldness of space, 150 million km away, to temperatures up to 500 ºC reached when it will be a mere 46 million km away, closer than Mercury.
Solar Orbiter is an ESA-led mission with strong NASA participation. The spacecraft was built and is being tested by Airbus.

NASA’s historic Parker Solar Probe mission that launched Aug. 12, 2018 from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida will revolutionize our understanding of the Sun. The Parker Solar Probe spacecraft will travel through the Sun’s atmosphere, closer to the surface than any spacecraft before it, facing brutal heat and radiation conditions — and ultimately providing humanity with the closest-ever observations of a star. This is a look at the moments leading up to T-Zero for NASA’s mission to “touch” the Sun.
NASA’s Parker Solar Probe mission launched Aug. 11 from Cape Canaveral Air Force Station in Florida. The mission will be the first to fly directly through the Sun’s corona – the hazardous region of intense heat and solar radiation in the Sun’s atmosphere that is visible during an eclipse. It will gather data that could help answer questions about solar physics that have puzzled scientists for decades. Gathering information about fundamental processes near the Sun can help improve our understanding of how our solar system’s star changes the space environment, where space weather can affect astronauts, interfere with satellite orbits, or damage spacecraft electronics.
The Parker Solar Probe will be the first-ever mission to “touch” the Sun, traveling directly into the Sun’s atmosphere about 4 million miles from the surface. Read the story: https://go.nasa.gov/2KEExYZ NASA launch schedule: https://go.nasa.gov/2JfklMB
The Sun contains 99.8 of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion miles away.
But even though the Sun has such a powerful pull, it’s surprisingly hard to actually go to the Sun: It takes 55 times more energy to go to the Sun than it does to go to Mars. Why is it so difficult? The answer lies in the same fact that keeps Earth from plunging into the Sun: Our planet is traveling very fast – about 67,000 miles per hour – almost entirely sideways relative to the Sun. The only way to get to the Sun is to cancel that sideways motion.
Since Parker Solar Probe will skim through the Sun’s atmosphere, it only needs to drop 53,000 miles per hour of sideways motion to reach its destination, but that’s no easy feat. In addition to using a powerful rocket, the Delta IV Heavy, Parker Solar Probe will perform seven Venus gravity assists over its seven-year mission to shed sideways speed into Venus’ well of orbital energy. These gravity assists will draw Parker Solar Probe’s orbit closer to the Sun for a record approach of just 3.83 million miles from the Sun’s visible surface on the final orbits.
Though it’s shedding sideways speed to get closer to the Sun, Parker Solar Probe will pick up overall speed, bolstered by Sun’s extreme gravity – so it will also break the record for the fastest-ever human-made objects, clocking in at 430,000 miles per hour on its final orbits.

The Sun unleashed powerful solar flares on 6 September, one of which was the strongest in over a decade. An X2.2-class flare was launched at 09:10 GMT and an X9.3 flare was observed at 12:02 GMT. An M-class flare was also observed two days earlier on 4 September.
The images were captured by the ESA/NASA Solar and Heliospheric Observatory, SOHO. The flares were launched from a group of sunspots classified as active region 2673.The shaded disc at the centre of the image is a mask in SOHO’s LASCO instrument that blocks out direct sunlight to allow study of the faint details in the Sun’s corona. The white circle added within the disc shows the size and position of the visible Sun.
A virtual journey, from our Solar System through the Milky Way, based on data from the first release of ESA’s Gaia satellite.
The journey starts by looking back at the Sun, surrounded by its eight planets. We then move away from the Sun and travel towards and around the Hyades star cluster, the closest open cluster to the Solar System, some 150 light-years away.
The 3D positions of the stars shown in the animation are drawn from the Tycho-Gaia Astrometric Solution (TGAS), which combines information from Gaia’s first year of observations with the earlier Hipparcos and Tycho-2 Catalogues, both based on data from ESA’s Hipparcos mission.
This new dataset contains positions on the sky, distances and proper motions of over two million stars. It is twice as precise and contains almost 20 times as many stars as the previous reference for astrometry, the Hipparcos Catalogue.
The journey continues showing the full extent size of the stars contained in the Tycho-Gaia Astrometric Solution, all relatively near to the Sun, in the overall context of our Milky Way galaxy.
The final Gaia catalogue will contain the most detailed 3D map ever made of the Galaxy, charting a billion stars – about 1% of the Milky Way’s stellar content – to unprecedented accuracy.
Acompanhe o Paxi numa viagem através do sistema solar, dos planetas rochosos interiores próximos do Sol, passando pelos planetas gigantes até à orla gelada onde se encontram os cometas.
Neste vídeo, destinado a crianças entre os 6 e os 12 anos de idade, o Paxi leva-nos a dar uma volta pelo sistema solar, visitando os oitos planetas e outros corpos menores como asteroides, cometas e o planeta anão Plutão.
Este vídeo é o segundo de uma série de animações em que o Paxi, a mascote educacional da ESA, aborda diferentes aspetos do sistema solar e do Universo, os segredos do planeta Terra e muito mais.
Alăturaţi-vă lui Paxi într-o călătorie prin Sistemul nostru solar, dinspre planetele interne stâncoase, situate mai aproape de Soare, trecând pe lângă planetele gigante şi până la marginea îngheţată a Sistemului, căminul cometelor.
În acest video, destinat copiilor cu vârste cuprinse între 6 şi 12 ani, Paxi ne conduce într-un tur al Sistemului nostru solar, vizitând toate cele opt planete şi alte corpuri cereşti minore, cum ar fi asteroizi, comete şi planeta pitică Pluto.
Acest videoclip este al doilea dintr-o serie de desene animate în care Paxi, mascota educaţională a ESA, abordează diferite aspecte ale Sistemului Solar, Universul, secretele planetei Pământ şi multe altele.
Steve Spangler launches a Solar Bag using the power of the sun. At least if Crazy Russian Hacker copies this idea, we know he probably bought the Solar Bag from us!
