Abu Dhabi observatory captures images of rare interstellar comet
Al Khatim Astronomical Observatory recorded 45 images of the rare celestial object – which Nasa says originated from outside our solar system – on Thursday night.
The observatory submitted its results to the Minor Planet Centre of the International Astronomical Union, making it the first Arab observatory to conduct scientific observations of the comet, state news agency Wam reported.
The comet, which has been named 3I/Atlas, is about 670 million km from Earth.
The Abu Dhabi team said sighting the comet was challenging as it appeared very faint and was visible only through large telescopes.
The observation lasted 45 minutes. The comet appears in the images as a moving dot, while the stars appear as streaks.
Nasa said the comet would remain visible to ground-based telescopes until September, after which it will be passing too close to the Sun to be observed.
It is expected to reappear on the other side of the Sun by early December, once again allowing for observation.
'The comet poses no threat to Earth and will remain at a distance of at least 1.6 astronomical units (about 150 million miles or 240 million km),' a statement from the US space agency read.
'It is currently about 4.5 au from the Sun. 3I/Atlas will reach its closest approach to the Sun around October 30, at a distance of 1.4 au – just inside the orbit of Mars.'
The celestial object, originally called A11pl3Z, was first reported by the Asteroid Terrestrial-impact Last Alert System (Atlas) survey telescope in Río Hurtado, Chile, on Tuesday.

NASA selects six companies to provide OTV studies
NASA will use the findings to guide mission design, planning, and launch strategies, with potential expansion to larger payloads and less risk-tolerant missions. NASA has selected six companies to produce studies focused on lower-cost ways to launch and deliver spacecraft of various sizes and forms to multiple, difficult-to-reach orbits. The firm-fixed-price awards comprise nine studies with a maximum total value of approximately $1.4m. The awardees are Arrow Science and Technology, Blue Origin, Firefly Aerospace, Impulse Space, Rocket Lab and United Launch Services. Joe Dant, orbital transfer vehicle strategic initiative owner for the Launch Services Program at NASAs Kennedy Space Centre in Florida, said: 'With the increasing maturity of commercial space delivery capabilities, were asking companies to demonstrate how they can meet NASAs need for multi-spacecraft and multi-orbit delivery to difficult-to-reach orbits beyond current launch service offerings. This will increase unique science capability and lower the agencys overall mission costs.' Each of the six companies will deliver studies exploring the future application of orbital transfer vehicles for NASA missions. Arrow will partner with Quantum Space for its study. Quantums Ranger provides payload delivery service as a multi-mission spacecraft engineered for rapid maneuverability and adaptability, enabling multi-destination delivery for missions from low Earth orbit to lunar orbit. Blue Origin will produce two studies, including one for Blue Ring, a large, high-mobility space platform providing full-service payload delivery, on-board edge computing, hosting, and end-to-end mission operations. It uses hybrid solar-electric and chemical propulsion capability to reach geostationary, cislunar, Mars, and interplanetary destinations. The second is a New Glenn upper stage study. Fireflys line of Elytra orbital vehicles offers on-demand payload delivery, imaging, long-haul communications, and domain awareness across cislunar space. Fireflys Elytra Dark is equipped to serve as a transfer vehicle and enable ongoing operations in lunar orbit for more than five years. Impulse Space will produce two studies. The company provides in-space mobility with two vehicles, Mira and Helios. Mira is a high-thrust, highly maneuverable spacecraft for payload hosting and deployment, while Helios is a high-energy kick stage to rapidly deliver payloads from low Earth to medium Earth orbits, geostationary orbits and beyond. Rocket Labs two studies will feature the upper stage of the companys Neutron rocket, as well as a long-life orbital transfer vehicle based on its Explorer spacecraft. Both vehicles are equipped with their own propulsion systems and other subsystems for missions to medium Earth and geosynchronous orbit and deep space destinations like the Moon, Mars, and near-Earth asteroids. United Launch Alliance will assess the cislunar mission capabilities of an extended-duration Centaur V upper stage. Centaur would be capable of directly delivering multiple rideshare spacecraft to two different orbital destinations in cislunar space, avoiding the need for an additional rocket stage or orbital transfer vehicle. The studies will be complete by mid-September. NASA will use the findings to inform mission design, planning, and commercial launch acquisition strategies for risk-tolerant payloads, with a possibility of expanding delivery services to larger-sized payloads and to less risk-tolerant missions in the future. NASAs Launch Services Programme selected providers through the agencys VADR (Venture-Class Acquisition of Dedicated and Rideshare Launch Services) contract, which helps foster growth of the US commercial launch market, enabling greater access to space at a lower cost for science and technology missions.

UAE skywatchers prepare for rare total lunar eclipse, supermoons and meteor showers
The remaining months of the year will bring a series of dazzling celestial events to the UAE, from a total lunar eclipse to three supermoons in a row. The first half of the year was quiet for skywatchers, with only a handful of minor events to light up the sky. Even the much-anticipated Perseids meteor shower this week was dimmed because of a bright full Moon. 'The next half of 2025 is going to be spectacular for stargazers … It's going to be a fantastic few months under the stars,' Khadijah Ahmed, operations manager at the Dubai Astronomy Group, told The National. Rare total lunar eclipse Next month, the Moon will pass completely into Earth's shadow, on the night of September 7, creating a rare total lunar eclipse. Often called a Blood Moon because of its coppery-red hue, it will be visible across the UAE and will be the longest event of its kind since 2022. The total eclipse will occur at 9.30pm GST and last for about 20 minutes. Ms Ahmed said it will be one of the most striking lunar events in recent years and can be enjoyed without any special equipment. 'This is one of the rare astronomical events happening in the UAE in 2025,' she said. 'We will host an event for the eclipse and encourage everyone to witness it. You don't need any special equipment – just go outside and look up.' The eclipse will also be visible in other parts of Asia, Australia, Africa and Europe. Supermoon season Supermoon season will follow soon after, with three back-to-back appearances in October, November and December. These take place when a full moon coincides with the Moon's closest point to Earth in its orbit, making it appear brighter and slightly larger than usual. The first will rise on October 7, known as the Hunter's Moon, followed by the Beaver Moon on November 5 and the Cold Moon on December 4. All three will be visible across the UAE, with moonrise just after sunset providing opportunities for photography and outdoor viewing. Meteor showers The Orionids meteor shower will light up the skies on October 21 and 22, followed by the Leonids on November 17 and 18. Geminids will be the final meteor shower of the year, peaking on December 13 and 14. It is among the best to observe, with 120 visible meteors each hour when the event is at its most intense. 'These meteor showers are visible without any equipment and are best viewed away from city lights,' said Ms Ahmed. The Dubai Astronomy Group usually holds viewing events for a fee for most of the meteor showers, with telescopes available. Additionally, the positions of Saturn on September 21 and Jupiter on December 7 will offer ideal opportunities to view these planets at their brightest and closest to Earth.
