High-altitude clouds in the atmosphere of Mars are likely made of frozen carbon dioxide and tend to be visible in the early morning hours just before sunrise when the sun's rays illuminate them at the best angle. Schmauß shared the new image on Flicker (opens in new tab) on Sunday, Apr. NASA first shared the images (opens in new tab) on March 22 but this new processing by NASA scientist Simeon Schmauß attempts to approximate how these clouds would appear to a human standing on the planet's surface. ![]() A sol is 40 minutes longer than Earth's day, and Perseverance has to date spent 753 sols on Mars. Perseverance took this image on its 738th Martian day, or sol, which was March 18 on Earth. ![]() Monday, April 3, 2023: NASA's Perseverance Mars rover sent home this beautiful postcard capturing rare high-altitude clouds above the Red Planet.

Planet's satellites have revealed that the amount of moisture held in the soil across the region is at a ten-year low. Earth-observing company Planet said in a blog post (opens in new tab). A below average amount of rainfall for six consecutive years has pushed the Sub-Saharan region into a humanitarian catastrophe, the U.S. The Horn of Africa, also known as the Somali Peninsula, is the easternmost region of Africa. Satellites help assess the scope of the disaster from orbit. Wednesday, April 5, 2023: Countries of the east African region known as the Horn of Africa are struggling with a prolonged drought brought on by record-low rainfall. – Tereza Pultarova Earth-observing satellite captures rare photo of Jupiter and its moon JUICE will even enter orbit around one of those moons, the solar system's largest moon Ganymede, and will thus become the first spacecraft in history to orbit a moon other than Earth's own. After arriving at its destination in the early 2030s, the spacecraft will study the gas giant, but mostly focus on three of its four main moons: Ganymede, Callisto and Europa. JUICE is Europe's first attempt to reach Jupiter, the largest planet of the solar system. Fortunately, that one second launch window will be available for several weeks, opening once every day. Due to the complex trajectory that JUICE will follow, which involves multiple gravity assist flybys at planets of the inner solar system, the mission will have to launch within a specific second in order for all its path's elements to be in alignment. If all goes to plan, the rocket with JUICE atop, will blast off from Europe's spaceport in Kourou, French Guiana, on Thursday (April 13) at 8:15 a.m. ![]() ![]() Wednesday, April 12, 2023: Europe's Jupiter explorer JUICE is encased in the nose cone of the Ariane 5 rocket during the rocket's launch pad rollout ahead of the mission's Thursday launch.

The artificial intelligence algorithm called principal-component interferometric modeling, or "PRIMO," fills gaps in the measurements taken by the Event Horizon Telescope, creating a fuller image. After processing with artificial intelligence algorithms, the ring of accreting matter appears much narrower and more defined. Produced by the worldwide network of radio telescopes known as the Event Horizon Telescope, the image features a blurry ring of shining matter that is falling into the pitch-dark black hole. The image capturing the supermassive black hole at the center of the galaxy Messier 87 was originally released in 2019.
