The spacecraft successfully launched and delivered NASA astronauts Butch Wilmore and Suni Williams to the International Space Station in June. But what seemed like an eight-day jaunt turned into months of questions surrounding Starliner’s ability to return the crew safely to Earth. NASAAfter nearly three months, the Starliner spacecraft returned to Earth without the two test pilots after undocking from the space station Friday night and parachuting into the New Mexico desert early Saturday. Starliner is the first US-made capsule to parachute to a ground landing, rather than splashing into the ocean. It remains to be seen how and when Starliner will be certified to carry astronauts regularly to space.

Habitat loss, overfishingand their fate as bycatch in fishing nets have threatened porbeagle shark populations. Northwest Atlantic porbeagle sharks are listed as vulnerable on the International Union for Conservation of Nature Red List of Threatened Species. The team pieced together several factors that indicated the shark had been eaten and the tag excreted by a larger predator that gobbled up the shark, Anderson said. Unusual suspectsPorbeagles belong to a family called lamnid sharks, which also includes great white sharks and mako sharks. Gutteridge, who was not involved in the study, agrees that a white shark is the most likely culprit.

CNN —Jupiter’s moon Ganymede may have shifted on its axis when a massive asteroid smashed into it about 4 billion years ago, according to a new study. Ganymede, the largest moon in the solar system, is even bigger than Mercury and the dwarf planet Pluto. The crater left behind on Ganymede was 25% the size of the Jupiter moon, according to the study. Understanding how the impact altered the moon could reveal insights into its intriguing internal structure, Hirata said. “I want to understand the origin and evolution of Ganymede and other Jupiter moons,” he said.

Earth’s electric and magnetic fields and gravity cause charged particles in the ionosphere to flow away from Earth’s magnetic equator. Typically, plasma bubbles are long and straight because they form along Earth’s magnetic field lines. GOLD observations captured C-shaped and reverse C-shaped plasma bubbles close together in the ionosphere on October 12, 2020, and December 26, 2021. So far, GOLD has only observed two instances of the close pairings, but the C-shaped bubbles have the potential to disrupt communications. “Due to such wide view and continuous measurements, GOLD has allowed us to observe these mysteries within the ionosphere,” Karan said.

CNN —The northern lights could grace skies farther south than usual this week because of a solar storm that may affect Earth, according to the US National Oceanic and Atmospheric Administration’s Space Weather Prediction Center. The center issued a strong geomagnetic storm watch, known as a G3 — the third highest level out of five — for July 29 to July 31. Strong geomagnetic storms are infrequent, the Space Weather Prediction Center said, but they’re more common than the G5, or extreme, geomagnetic storm that occurred on May 10 and May 11. If the predicted G3 conditions occur, auroras could be visible as far south as Illinois and Oregon, the Space Weather Prediction Center said. Alerts issued by NOAA’s Space Weather Prediction Center and other agencies help the operators of power grids and commercial satellites to mitigate potential negative impacts from a solar storm.

Editor’s note: A version of this story appeared in CNN’s Wonder Theory science newsletter. Thousands of years ago, our ancestors produced the first maps of the stars and practiced alchemy, the precursor to chemistry. But ancient alchemists actually developed technology and discovered chemical elements that are still widely used today. Now, a new discovery links both astronomy and alchemy in one intriguing figure who lived during the Renaissance. Once the Starliner mission concludes, SpaceX will ferry a quartet of astronauts for NASA’s Crew-9 mission to the space station.

The covert nature of Brahe’s work was common among alchemists of the Renaissance, who kept their knowledge close to the vest. “Tungsten had not even been described at that time, so what should we infer from its presence on a shard from Tycho Brahe’s alchemy workshop?” Rasmussen said. In addition to serving as Brahe's home, Uraniborg functioned as a scientific center where students across Europe came to live and work. And Brahe himself wrote that the king was eager to support the scientist’s work in both astronomy and alchemy. Given the amount of gold found in Brahe’s remains, he may have also taken medicine containing potable, or drinkable, gold.

CNN —The Curiosity rover has made its most unusual find to date on Mars: rocks made of pure sulfur. “I think it’s the strangest find of the whole mission and the most unexpected,” said Ashwin Vasavada, Curiosity project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. Previously, while exploring Mars, NASA’s Spirit rover broke one of its wheels and had to drag it along while using the other five to drive backward. And Vasavada says it’s what inspired the team to “look behind” the Curiosity rover — otherwise they wouldn’t have seen the crushed sulfur.

The star is one of a binary pair, so the planet orbits the primary star, while the primary star orbits a secondary star. While Jupiter takes 4,000 Earth days to complete one orbit around the sun, hot Jupiters complete one orbit every few days. Astronomers use “eccentric” to refer to the shape of a planet’s orbit on a scale from zero to 1. “It’s a pretty extreme process in that the changes to the planet’s orbit are massive,” Millholland said. Discovering a second hot Jupiter precursor is helping astronomers to confirm the idea that high-mass gas giants transform into hot Jupiters as they migrate from eccentric to circular orbits, the researchers said.
