A massive filament eruption carved a 250,000-mile-long "canyon of fire" into the sun — and sent a CME sailing into space.
The impact that carved out the moon's huge South Pole-Aitken basin may explain the puzzling differences between the lunar near and far sides.

A SpaceX Falcon 9 rocket launched 26 Starlink internet satellites into low Earth orbit after lifting off from Vandenberg Space Force Base in California on July 15, 2025.
The search for habitable exoplanets is a key priority and sits at the pinnacle of exoplanet science. The science community stated that clearly in the 2020 Survey on Astronomy and Astrophysics 2020 (Astro2020). That survey identified the search for habitable worlds as a priority in their Pathways to Habitable Worlds report.
Astronomers have detected a massive, Ultra-Hot Jupiter that's getting dangerously close to its star. It's more massive than Jupiter and orbits its star more quickly than Mercury orbits the Sun. There are only three possible outcomes, and none of them are good for the planet.
New research indicates that cellular "pockets" that are the first step toward protocells, the precursors of life, could form in the methane seas of Saturn's moon Titan.

SpaceX plans to launch 24 of Amazon's Project Kuiper broadband satellites early Wednesday morning (July 16), the 56th anniversary of the Apollo 11 liftoff.
'We had an idea for a meat planet' — Revenge of the Savage Planet game director Alex Hutchinson talks strange new worlds and mocking corporate spaceflight.
Recently discovered interstellar comet 3I/ATLAS may be a very old object indeed.
Very massive stars (VMSs)have had a massive impact on the formation of our universe. However, there aren’t very many of them, with only around 20 known specimens in the Milky Way and Large Magellanic Cloud. Even observing those is difficult for the current generation of telescopes, which is where an unexpected technological champion might play a role. According to a new paper by Fabrice Martins of CNRS and a group of European and American researchers, the upcoming Habitable World Observatory (HWO) might be our most useful tool when it comes to finding these elusive giants.
As humanity sets its sights on long duration missions to the Moon, Mars, and beyond, keeping astronauts healthy will be as critical as building rockets or habitats. In the harsh environment of space, the human body faces challenges that Earth never prepared us for including isolation, microgravity, and radiation that disrupt the immune system, increasing the risk of infection, chronic inflammation, and disease. Interestingly, new research on HIV is revealing lessons that could help future explorers live sustainably, regenerate resources in closed-loop systems, and even produce custom medicine far from Earth.
Trans-Neptunian Objects (TNO) are some of our Solar System's lesser-known objects. They number in the thousands, and they get their name from their orbits. These dwarf planets that orbit the Sun at a greater average distance than Neptune does. Pluto is the group's most well-known member, having been demoted from planet to TNO in recent years.
Each summer, skywatchers around the world look forward to the famous Perseid meteor shower, but often overlook four lesser showers that peak between July 29 and Aug. 16.
