NASA researchers discover what happened to Mars’ water
- Mars, once rich with flowing water, is now a cold, dry desert, prompting researchers to uncover clues about its missing water using NASA's Hubble Space Telescope and the MAVEN mission.
- Researchers like John Clarke are focusing on the theory that Mars' water either froze into the ground or broke into hydrogen and oxygen atoms, with the lighter hydrogen escaping into space.
- By observing hydrogen atoms escaping Mars' atmosphere, researchers estimate the amount of water lost over time, unraveling the planet's transformation from a wet world to its current state.
- Mars' dynamic atmosphere experiences rapid temperature changes influenced by its distance from the Sun, impacting water loss processes over the planet's history.
- The collaboration between Hubble and MAVEN has provided insights into hydrogen escape rates on Mars, shedding light on the fate of the planet's water and ancient climate.
- Studying Mars' water history is crucial for understanding Earth-sized planets in habitable zones, offering insights into planetary evolution and the potential for life beyond our solar system.
- The MAVEN mission, launched in 2013, aims to study Mars' upper atmosphere to unravel its atmospheric loss, climate change, and the disappearance of liquid water on the planet.
- MAVEN's major findings include discoveries about atmospheric erosion during solar storms, processes leading to atmospheric sputtering, and insights into Martian winds and electric currents.
- Ongoing research by MAVEN continues to provide valuable data on Mars’ past, atmospheric processes, and the potential for human habitation on the planet.
- The study's collaboration with Hubble and MAVEN, along with ongoing research, contributes to a deeper understanding of Mars' water loss, atmospheric dynamics, and planetary evolution.

NASA diagnoses fracture in a 'huge cosmic bone' using X-ray observatory
- NASA's Chandra X-ray Observatory detected a fracture in a cosmic 'bone' in the Milky Way using radio data from MeerKAT radio array and the National Science Foundation’s Very Large Array.
- The fracture is believed to have been caused by an impact from a pulsar, a rapidly spinning neutron star that emits radiation at regular intervals.
- The 'bone' is actually a galactic center filament called G359.13, located 26,000 light-years from Earth and about 230 light-years long.
- The fracture is speculated to have been caused by a high-speed collision with the pulsar, distorting the filament's magnetic field.

Find the Keystone in Hercules, and the Hercules Cluster M13
- Hercules, a faint constellation, contains the easy-to-see Keystone asterism, which is a star pattern situated between the bright stars Vega in Lyra the Harp and Arcturus in Boötes the Herdsman.
- The Keystone asterism can be located by using the star Vega in Lyra the Harp or in conjunction with the star Arcturus in Boötes the Herdsman, about 1/3 of the way from Vega to Arcturus.
- Once the Keystone is found, it can be used to locate M13, also known as the Hercules cluster, a famous globular star cluster in Hercules which appears as a dim smudge or a fuzzy star through binoculars or a telescope.
- The best time to view the Keystone and the Hercules cluster is later in the evening when they swing high overhead after midnight and before dawn in the western sky.
