NASA published the first images of Earth taken by astronauts aboard Artemis II as the crew travels toward the Moon.The mission carries Christina Koch, Victor Glover, Reid Wiseman, and Jeremy Hansen, marking the first crewed journey toward lunar orbit since the Apollo program.The spacecraft Orion reached the halfway point, about 219,000 km from Earth, and continues toward a planned lunar orbit in the coming days.Launched from Florida earlier this week, the mission follows a free-return trajectory, looping around the Moon before heading back to Earth.Artemis II is a key step toward returning humans to the lunar surface and preparing for future missions to Mars.  

The Ministry of Municipality on Saturday observed the Earth Hour event by switching off nonessential lights at its compounds for an hour, from 8:30 p.m. to 9:30 p.m.In a post on the X platform, the ministry clarified that its participation in this global event came as part of awareness-promotion efforts on the criticality of rationalizing power and backing climate change-combating efforts, as well as in support of achieving Qatar National Vision 2030.

The Ministry of Environment and Climate Change (MECC) participated in Earth Hour on Saturday by turning off the lights in its main building (Al Adeed Tower) and all its affiliated buildings for one hour.The event took place from 8:30 p.m. to 9:30 p.m., as part of the global environmental initiative to promote awareness about climate change.The Ministry highlighted that its participation reflected support for global environmental initiatives and its commitment to promoting societal awareness of the importance of rationalizing power consumption through practices that help reduce emissions and conserve natural resources.Earth Hour is an annual global event held at 8:30 p.m. local time in each country on the final Saturday of March.It is marked by turning off lights and nonessential electrical devices for one hour, with the objective of strengthening widespread awareness about climate change issues and encouraging responsible environmental behaviors.

LuLu Hypermarket in Qatar reaffirmed its commitment to environmental sustainability by participating in the global Earth Hour 2026 initiative Saturday. Following the directive of the Ministry of Environment and Climate Change, encouraging individuals and institutions nationwide to observe Earth Hour by switching off lights and non-essential electrical appliances from 8.30pm to 9.30pm, LuLu outlets across Qatar turned off their external lights, including the prominent D-Ring Road location. The symbolic gesture underscores LuLu Hypermarket’s strong alignment with national sustainability goals and highlights its ongoing dedication to energy conservation and environmental responsibility. By participating in Earth Hour, the company continues to demonstrate leadership in promoting responsible and sustainable business practices. LuLu Hypermarket remains committed to supporting government-led environmental initiatives and advocating for eco-friendly practices, while inspiring communities to take meaningful steps toward a greener and more sustainable future. 

The Parliament House before the lights were turned off for Earth Hour in Islamabad, Pakistan, Saturday. 

The Qatar Calendar House on Thursday said that planet Earth will reach the closest point in its orbit around the Sun — known as perihelion—on the evening of the day after tomorrow, Saturday, 14 Rajab 1447 AH, corresponding to 3 January 2026. At that time, Earth will be at an approximate distance of 147 million kilometers from the Sun, about five million kilometers closer than it was in July of last year.Dr. Bashir Marzouq, an astronomy expert at the Qatar Calendar House, stated that Earth reaches perihelion at the beginning of January each year, while it reaches the farthest point in its orbit around the Sun-known as aphelion-during the month of July.He noted that variations in the distance between the Earth and the Sun are not the cause of climatic changes on Earth's surface. Rather, this variation plays an important role in determining the lengths of the four astronomical seasons. He emphasized that this phenomenon is entirely natural and has no negative effects on the inhabitants of the planet, contrary to claims made by non-specialists.Dr. Marzouq further pointed out a striking paradox: despite Earth being closest to the Sun in January, which corresponds to winter in the Northern Hemisphere, temperatures are low. Conversely, when Earth is farthest from the Sun in July—summer in the Northern Hemisphere, temperatures are high. This is due to the angle of incidence of solar radiation. In winter, the Sun's rays strike the Northern Hemisphere at a more oblique angle, causing them to pass through a longer path in the atmosphere and lose a significant portion of their heat. In summer, the Sun's rays fall more directly, traverse a shorter atmospheric path, and therefore retain more of their heat. The situation is entirely reversed in the Southern Hemisphere.It is worth noting that Earth, like the other planets, orbits the Sun in an elliptical (oval-shaped) path, with the Sun located at one of the two foci of the ellipse. Consequently, Earth has the nearest point in its orbit called perihelion and the farthest point known as aphelion.

US President Donald Trump, currently visiting Tokyo, and Japanese Prime Minister Sanae Takaichi signed an agreement on Tuesday to secure supplies of rare earth minerals.A White House statement indicated that Trump and Takaichi signed a joint agreement during their meeting aimed at securing supplies of rare earth minerals and critical minerals.Kyodo News Agency reported that Takaichi and Trump agreed to continue working to develop bilateral relations between the two countries in various fields.Takaichi, who became Japan's first female prime minister last week, pledged to build a new "golden age" for the Japan-US alliance, while praising Trump's role in promoting peace in the Middle East.

The China National Space Administration (CNSA) on Wednesday unveiled a remarkable image of the Tianwen-2 probe alongside Earth, captured during its deep-space journey. The newly released image, acquired by a monitoring camera mounted on the probe's robotic arm, showcases China's five-starred red flag and the white return capsule against the backdrop of a distant, blue Earth. According to CNSA, the Tianwen-2 probe is currently approximately 43 million kilometers from Earth and 45 million kilometers from the asteroid 2016HO3. The probe has successfully completed a series of in-orbit tests, including the deployment of sampling devices and self-checks of electronic devices. All systems are reported to be functioning normally, while onboard instruments have begun collecting valuable scientific data on the space environment, according to the CNSA. China launched its first asteroid sample-return mission, Tianwen-2, on May 29 — an endeavour to shed light on the formation and evolution of asteroids and the early solar system. The mission aims to achieve multiple goals over a decade-long expedition: collecting samples from near-Earth asteroid 2016HO3 and exploring the main-belt comet 311P, which is farther from Earth than Mars.
