NASA probe takes images from 'closest' ever spot from the Sun
Washington (dpa) US space agency NASA on Thursday released images captured by a probe within the Sun's atmosphere. NASA's Parker Solar Probe started its closest approach to the Sun on December 24, getting as close as 6.1 million kilometres to the solar surface, the space agency said. NASA said the images were "taken closer to the Sun than we've ever been before," and showed features in the corona and solar wind - a constant stream of electrically charged particles from the star that rage across the solar system at speeds exceeding 1 million miles an hour.
The Parker Solar Probe, about the size of a small car, launched in 2018 and in 2021 became the first spacecraft to enter the Sun's atmosphere.

"Parker Solar Probe has once again transported us into the dynamic atmosphere of our closest star," said NASA's Nicky Fox. "We are witnessing where space weather threats to Earth begin, with our eyes, not just with models. This new data will help us vastly improve our space weather predictions to ensure the safety of our astronauts and the protection of our technology here on Earth and throughout the solar system."The images were taken with the Wide-Field Imager for Parker Solar Probe (WISPR). The tool, about the size of a shoebox, is the only imaging tool on the probe. The new WISPR images show the corona and solar wind as well as the heliospheric current sheet - the boundary where the star's magnetic field direction switches from northward to southward. The tool also captured the first high-resolution images of the collision of multiple coronal mass ejections, or CMEs, which are a key driver of space weather."In these images, we're seeing the CMEs basically piling up on top of one another," said Angelos Vourlidas from the Johns Hopkins Applied Physics Laboratory, which designed, built and operates the spacecraft.
"We're using this to figure out how the CMEs merge together, which can be important for space weather," Vourlidas said.

Oman's Etlaq Spaceport: A new hub for the new space economy
MUSCAT: In today's space race, it's the lean and adaptive — not the legacy giants — who are setting the pace. As private space companies push the boundaries of propulsion systems, small satellite tech and reusable launch vehicles, they're increasingly on the lookout for launch partners that offer more than just real estate. One of the newest — and most surprising — answers to that call is Oman. Etlaq Spaceport, located near the coastal city of the Wilayat of Al Duqm, Al Wusta Governorate, is gaining attention from space startups across the globe. Not because it's the biggest, but because it's fast, flexible and surprisingly accessible. Backed by Oman's National Aerospace Services Company (NASCOM), the spaceport has quickly positioned itself as a responsive, startup-friendly gateway — an emerging alternative to heavily booked and bureaucratically burdened launch complexes. Stellar Kinetics has chosen Etlaq for the maiden launch of its Kea-1 vehicle. 'The upcoming mission will be the inaugural launch of the Kea-1 vehicle, offering a unique opportunity to test orbital class systems such as stage separation mechanisms and active guidance under unprecedented timelines,' stated a company representative. Their mission is part of the Duqm-2 suborbital flight scheduled this year. Stellar Kinetics is part of a growing shift in the new-space economy, where iterative testing, agile development and hardware validation happen quickly — and repeatedly. Traditional launch sites can involve long wait times, complex onboarding and rigid launch windows. For smaller companies trying to keep pace with tight funding milestones and evolving designs, those delays can be deal-breakers. Etlaq's agile structure is built to answer that need. Through its Genesis Programme, the spaceport enables launch service providers to move from planning to liftoff in as little as 14 weeks. This type of responsive launch cadence is rare in a market dominated by legacy infrastructure. Stellar Kinetics has chosen Etlaq for the maiden launch of its Kea-1 vehicle. Beyond timeline acceleration, startups are drawn to Etlaq's partnership mindset. Rather than offering pre-packaged services, the spaceport provides custom launch support — vehicle integration, environmental testing and mission coordination tailored to the provider's needs. For startups that don't have the scale or capital of larger aerospace firms, this degree of access and flexibility is a game-changer. Even research payloads are finding opportunities in Oman. Onboard Duqm-2 will be two international experiments from the UK's university-led JUPITER programme and Taiwan's SIGHT Space. The teams are sending a compact CubeSat and an even smaller PocketQube to conduct microgravity experiments and onboard systems validation — objectives that are often delayed, deprioritised and prohibitively expensive in larger missions elsewhere. Oman's location, near the equator with direct ocean overflight zones, gives technical advantages for a wide range of orbits. But more importantly for these startups, the country is building a framework that supports innovation: clear regulatory pathways, public-private collaboration and an openness to emerging technologies. While Oman's space programme is still in its early stages, its engagement with foreign startups is already shaping a reputation: not as a competitor to the world's spacefaring superpowers, but as a strategic enabler for the next generation of launch providers. In this new era of space access, Etlaq offers something rare — speed, access and support for those trying to build the future of flight. Startups aren't just coming to Oman to launch. They're coming here to learn fast, move fast and fly again.

UAE observatory captures rare interstellar comet 3I/ATLAS, only the third ever discovered
An astronomical breakthrough has taken place in the UAE, as the Al Khatim Astronomical Observatory in Abu Dhabi successfully imaged a newly discovered interstellar comet—only the third ever recorded in human history. The object, named 3I/ATLAS, was discovered by NASA on July 1 using the ATLAS survey telescope in Chile. Classified as an interstellar comet, it originated from another solar system and has been drifting through deep space for billions of years before entering ours just days ago. UAE captures rare interstellar comet The '3I' prefix signifies its status as the third interstellar object ever detected, following ʻOumuamua in 2017 and 2I/Borisov in 2019. The comet is currently about 670million kilometres from the Sun, travelling at a staggering 221,000 kilometres per hour. It poses no threat to Earth, with its closest approach expected to be 240 million kilometres away. On July 3, astronomers at Al Khatim Observatory captured the faint comet —currently at magnitude 17.5—over a 45-minute session, producing 45 long-exposure images. While the stars appear as streaks in the photographs, the comet is visible as a moving dot. The UAE observatory's findings have been officially submitted to the Minor Planet Centre (MPC) of the International Astronomical Union (IAU), making Al Khatim the first Arab observatory to document scientific observations of 3I/ATLAS. The comet will reach its closest point to the Sun on October 30, 2025, at a distance of 210 million kilometres and a predicted brightness of magnitude 11, making it faintly visible through amateur telescopes.
