Rare 'smiley face' planetary alignment to form in night sky this week
A 'smiley face' planetary alignment will light up skies across the world this Friday.
Known as a triple conjunction, the celestial event will bring Venus, Saturn and the crescent moon into a triangular formation near the horizon.
The two planets will act as the eyes of the smile, while the crescent will form its mouth, according to Nasa solar system ambassador Brenda Culbertson. Of the two planets, Venus will be brighter.
The alignment will be visible for about an hour to anyone from Europe, parts of Africa, and the Americas. However, it will not be visible from the Gulf region with the naked eye.
'The planets and the Moon will indeed be visible in the UAE sky, but the smiling face formation will not be seen in the UAE or any of the GCC countries,' Ibrahim Al Jarwan, chairman of the Emirates Astronomy Society and member of the Arab Union for Astronomy and Space Sciences, told The National.
He said Venus, Saturn and the waning crescent Moon, will rise together in a compact group of no more than three degrees across the sky starting at 4am UAE time.
'The grouping will appear striking in the dawn sky, with the Moon leading ahead of the two planets,' he said. 'As of 6am, with sunrise at 5.45am UAE time, the alignment will no longer be visible to the naked eye.'
At around 9am UAE time, the alignment will form a distinct smile-like pattern with Venus and Saturn as the eyes and the crescent Moon as the mouth. 'But this will only be visible to observers in far western Europe, parts of Africa, and the Americas.'
'The smile-shaped alignment will not be visible from the Arabian Gulf or the Arabian Peninsula, but we will still be able to enjoy seeing the bright planets and the crescent Moon before sunrise,' he added.
A cosmic week
The Lyrid meteor shower will also reach its peak this week, in the early hours of Wednesday, April 23, offering a chance to witness bright streaks of light dash across the sky.
The Lyrids, which originate from debris left behind by Comet C/1861 G1 Thatcher, are one of the oldest known meteor showers, with records of observations dating back more than 2,600 years.
While not the most intense of meteor showers, they are known for fast-moving meteors and the occasional bright fireball.
The next meteor shower will not be visible in the UAE until August, when the Perseids will light up the night skies. About 100 to 150 meteors are expected to streak across the skies.

UAE astronomers detect exoplanets orbiting distant stars
Astronomers in the UAE have detected exoplanets orbiting stars far beyond the solar system, the Abu Dhabi-based International Astronomy Centre announced. Al Khatem Astronomical Observatory, located deep in the Abu Dhabi desert, worked in partnership with the NASA Transiting Exoplanet Survey Satellite (TESS) mission. The astronmers analysed subtle changes in the brightness of stars to detect the transit of planets in front of them - a technique used to discover exoplanets. Eng. Khalfan Al Nuaimi, Chairman of the International Astronomy Center, said the detection of these planets is based on preliminary data provided by the TESS telescope, and is being verified on Earth through a global network of specialised observatories. Eng. Mohammed Shawkat Awda, Director of the International Astronomy Center, said that the Al Khatim Observatory officially joined the TESS Follow-Up Observing Program (TFOP) program in June 2024, after completing a rigorous training program conducted by international experts, followed by a successful practical test to observe one of the candidate planets. He explained that since joining, it has conducted a series of nighttime observations, each lasting between four and seven hours, focusing on 12 stars suspected of having planets. He noted that using its main telescope, it was able to transform the status of 10 of these stars from "candidate planets" to "confirmed planets," an achievement that demonstrates the precision of the observatory's research. Official documents from the Global Programme indicate that the Khatem Observatory achieved these results independently, reflecting the efficiency of its equipment and the accuracy of the observations it provides, especially in light of the environmental challenges facing ground-based observations. Awda emphasised that this contribution represents an important scientific step for the UAE in the field of space exploration, placing it in a leading position in the search for planets that may be habitable, or providing new insights into the formation and evolution of planets in distant galaxies.

In April this year, the UAE marked the anniversary of the first human spaceflight, continuing its significant contributions to space exploration led by its qualified national workforce and ambitious youth. This year's anniversary highlighted the UAE's emergence as a leading space exploration success story in the Arab and regional spheres. Its accomplishments include groundbreaking projects and the development of a skilled generation of astronauts, administrators and technical personnel. The UAE achieved a historic milestone in the first quarter of this year by launching six satellites: Thuraya 4, MBZ-SAT, Al Ain Sat-1, HCT-SAT 1, the second phase of Foresight Constellation, and Etihad-SAT. Recent milestones also included February's agreement between Mohammed Bin Rashid Space Center (MBRSC) and Thales Alenia Space. Under the agreement, Thales Alenia Space will be a strategic partner in the development of the Pressure Equalisation Unit of the Gateway Lunar Space Station. The UAE's participation in this project signifies a major step in its strategy to establish a prominent global presence in space science and technology. The UAE joined the Gateway project in January 2024 alongside the U.S., Japan, Canada, and the European Union, and announced its intent to send the first Emirati and Arab astronaut to lunar orbit.
