The European Space Agency has released an image showing the south pole of the Sun. This image was taken on March 23, 2025, but was revealed yesterday on June 11, 2025. These new images from the Solar Orbiter spacecraft show a view of the Sun that has never been recorded before. Solar Orbiter spent its last months tilting its orbit to 17 degrees underneath the solar equator, bringing the elusive south pole to view, which could never be done before.

Images Found had Visible UV Wavelengths

Carolle Mundell, the director of Science, told Live Science that today, we reveal the first ever views of the Sun’s pole by humankind. The new images caught the solar pole in broader, visible and ultraviolet wavelengths, with the help of three of the Solar Orbiter’s 10 instruments. These caught colourful confetti of the Sun’s data, with fathomable tangles of its magnetic field. It flips with high velocity movement of chemicals and makes up the solar wind.

Flips of the Magnetic Field Due to Solar Activity

According to ESA, these data will provide an understanding of the solar wind, space weather and the 11-year activity of the Sun. Through the measurement of the Solar Orbiter’s Polarimetric and Helioseismic Imager instrument, the Sun can be seen as throwing out flares in overdrive during the period of peak activity.

This mess of magnetic fields is temporary and flips after every 11 years. This signifies the end of the maximum solar activity and the beginning of the transition towards the relative calm of the next solar minimum. Further, after five to six years, when the solar minimum begins, the Sun’s poles show only one type of magnetic polarity.

First Step towards the Sun

With the coming years, there will be many stances for the Solar Orbiter to test further. Through the little help of the gravitational pull of Venus, it will tilt its orbit again from the solar equator to 24 degrees in December 2026, 33 degrees in June 2029. This will help us know the Sun from different regions and, in turn, know about the magnetic field, solar wind and activity.

NISAR Launches July 30: A NASA-ISRO Satellite to Track Earth’s Changes

The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, a joint Earth science mission, is now set for launch from India’s Satish Dhawan Space Centre. The pickup-truck-sized spacecraft was encapsulated in the nose cone of an Indian Geosynchronous Satellite Launch Vehicle and is scheduled to lift off on Wednesday, July 30 at 8:10 a.m. EDT (5:40 p.m. IST). Once in orbit, its dual-frequency radars will circle Earth 14 times a day, scanning nearly all of the planet’s land and ice surfaces every 12 days. It will provide data to help scientists monitor soil moisture and vegetation, and better assess hazards like landslides and floods.

International Collaboration and Launch Readiness

According to the official website, NISAR reflects a significant NASA–ISRO partnership. NASA’s Jet Propulsion Laboratory (JPL) built the long-wavelength L-band radar, and India’s Space Applications Centre built the shorter-wavelength S-band radar. This dual-frequency design makes NISAR the first Earth satellite to carry two radar systems, underscoring the mission’s unique collaboration.

The spacecraft is now integrated into its launch vehicle at India’s Satish Dhawan Space Centre. On July 28 NASA announced NISAR had been encapsulated in the payload fairing of an ISRO Geosynchronous Satellite Launch Vehicle on the pad. The GSLV is scheduled to lift off at 8:10 a.m. EDT (5:40 p.m. IST) on Wednesday, July 30.

Advanced Dual-Frequency Radar

NISAR carries a novel dual-frequency radar system. The satellite’s instruments operate at L-band (25 cm) and S-band (10 cm) wavelengths. The longer L-band waves can penetrate forests and soil to sense moisture and land motion, while the shorter S-band waves pick up fine surface details like vegetation moisture and roughness. This combination lets NISAR detect both large-scale and fine-scale changes.

From orbit, NISAR will circle Earth 14 times per day, scanning nearly all land and ice surfaces twice every 12 days. Its data will track changes like the advance or retreat of polar ice sheets and slow ground shifts from earthquakes, and will also aid agriculture and disaster planning by helping monitor crops and prepare for floods and hurricanes.

Doomed Exoplanet TOI-2109b Spirals Toward Its Star with Three Possible Fates

Doomed Exoplanet TOI-2109b Spirals Toward Its Star with Three Possible Fates

The gas giant TOI-2109b is more than five times as massive as Jupiter, and resides in a perilous orbit 870 light-years from our planet. As an “ultrahot Jupiter,” it completes a lap around its parent star in a mere 16 hours, the briefest orbit of any such planet known. It is baking its atmosphere to broiling temperatures, and inching closer to oblivion in an orbit that is slowly pulling it in toward its parent sun. Using archived space telescope data from TESS and Cheops, astronomers have observed the testimony of this inevitable spiral, and contemplated three (wildly divergent) possible fates of the doomed planet.

Fates for TOI-2109b

According to the new research, conducted with data from NASA’s TESS and ESA’s Cheops missions shows that TOI-2109b’s orbit is decaying — a process it will continue for thousands of Earth’s years to come by 10 seconds over three Earth years. This proves that it is in a process of slow in fall. If the decay becomes worse, the planet may start falling directly into its host star and create a luminous flare, just like ZTF SLRN-2020. Alternatively, the star’s tidal forces could permanently warp the planet and rip it asunder.

A Potential Planetary Rebirth

There is a third, less-tragic possibility which could happen through a process of photoevaporation, in which strong radiation from the hosting star removes TOI-2109b’s gaseous envelope to reveal its rocky core. If the planet shrinks quickly enough, it might survive the process, avoiding its destruction by spiraling within its eternal Roche limit, and settling as a super-Earth or Neptune-sized blow-up hard relic. Then TOI-2109b would be an odd, rare opportunity to witness up close how this process unfolds.

Hubble Spots Interstellar Invader Comet 3I/ATLAS for the First Time

The Hubble Space Telescope has taken its initial shots of comet 3I/ATLAS, a comet visiting us from beyond our solar system that recently fell apart — but not before it struck a pose for the cameras. It’s only the third such object ever known, after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019. The subject of numerous scientific tweets and some frantic searches by astronomers anxious to figure out just what it is — and where it came from — before it is gone into the pitch black of deep space forever, 3I/ATLAS was first sighted by the ATLAS survey telescope on July 1, 2025.

Ancient Interstellar Comet 3I/ATLAS Offers Clues to Planetary Systems Beyond Our Own

According to As per Space.com, recent studies indicate that 3I/ATLAS could be some 7 billion years old, well beyond the 4.6 billion years of our solar system. That’s an indication that the comet arose in the more ancient parts of the Milky Way, which would give researchers a rare glimpse of what the early days of other planetary systems were like. Undergraduate researcher Astrafoxen first flagged the Hubble images on Bluesky, noting the comet’s “nice and puffy” coma, despite interference from cosmic rays.

A newly available preprint paper has already revealed that 3I/ATLAS contains abundant water ice and a dust makeup resembling D-type asteroids—organic-rich bodies typically found in the outer solar system. Unlike ultrared trans-Neptunian objects, D-types are believed to have high carbon and silicate content, potentially shedding light on the comet’s deep-space origins and volatile chemistry.

The comet 3I/ATLAS was discovered just as the Vera C. Rubin Observatory was gearing up to carry out its initial observations of the heavens, dovetailing with the LSST’s expected discovery of many more interstellar objects in the coming decade.

Until then, 3I/ATLAS holds the astronomical spotlight. Its brief solar system passage offers a precious opportunity for researchers to analyse the material makeup of alien planetary systems. The Hubble images, now available for download, are expected to aid future papers as scientists continue to unravel the story of this ancient cosmic traveller.
