And it’s time to bid farewell to one of the most delightfully plucky robots ever to explore Mars. Other worldsThe Ingenuity helicopter, seen here on Mars in an image taken by the Perseverance rover on August 2, 2023, has flown for the last time. Ingenuity served as the Perseverance rover’s faithful companion and aerial scout for nearly three years since its maiden flight on April 19, 2021. A long time agoAiming to trace syphilis' origins, researchers used paleopathology techniques to study ancient human bones at the site Jabuticabeira II in Brazil's Santa Catarina state.

If the lander turns on again, it could make good on its objectives to collect unprecedented information about a region called the Sea of Nectar. The 1969 US moon mission Apollo 11 captured this oblique view of the large crater Theophilus at the northwest edge of the Sea of Nectar. Here's the first picture sent back by the Moon Sniper after it landed on the lunar surface. The Sea of Nectar is much smaller than its neighbor the Sea of Tranquility, which is over 540 miles (875 kilometers) across and is similarly smooth and flat. “After the Apollo missions, we brought back samples and learned they were essentially massive lava planes,” Osinski said.

☆ Hubble finds water vapor in small exoplanet’s atmosphere

CNN —Astronomers using the Hubble Space Telescope have detected water molecules in the atmosphere of a small, blazing-hot exoplanet 97 light-years from Earth. The planet, named GJ 9827d, is about twice Earth’s diameter, and it’s the smallest exoplanet found to have water vapor in its atmosphere, according to a new study. Starlight filtering through the planet’s atmosphere helped astronomers measure the signature of water molecules. It’s possible that the planet is a mini-Neptune with a hydrogen-rich atmosphere that contains water vapor. Or astronomers suspect that GJ 9827d could be a warmer version of Jupiter’s icy moon Europa, which contains an ocean beneath a thick, icy crust.

[1/2] An undated handout image shows an artistic rendering of the mass comparison of the star LHS 3154 and its planet LHS 3154b, and our own Earth and Sun. The mass ratio of this planet with its star is more than 100 times greater than that of Earth and the sun. "We discovered a planet that is too massive for its star," said Penn State astronomer Suvrath Mahadevan, one of the leaders of the study published this week in the journal Science. The planet, called LHS 3154 b, orbits at about 2.3% of Earth's orbital distance from the sun, circling its star every 3.7 days. So a very low mass star should have a disk that is also low mass.

The planet, about the mass of Neptune and more than 13 times as massive as Earth, was detected orbiting an ultracool M-dwarf star called LHS 3154 — which is nine times less massive than our sun. This graphic compares the sizes of our sun and Earth with the smaller, cooler LHS 3154 star and its orbiting planet, LHS 3154b. For example, small M dwarf stars are the most common throughout the Milky Way galaxy, and they typically have small, rocky planets orbiting them, rather than gas giant planets. “The planet-forming disk around the low-mass star LHS 3154 is not expected to have enough solid mass to make this planet,” Mahadevan said. A team of scientists led by Mahadevan built the HPF, which was designed to detect planets orbiting within the habitable zone of small, cool stars.

☆ Planet-forming disk detected around star in another galaxy for the first time

CNN —For the first time, astronomers have glimpsed a young star outside the Milky Way galaxy that’s ringed by a dense disk where planets may form. The massive star, called HH 1177, and its rotating disk were spotted in the Large Magellanic Cloud, a neighboring dwarf galaxy that’s about 160,000 light-years away. The gas and dust accumulate in a flat disk around the star, known as an accretion disk, as a result of strong gravitational forces. The Multi Unit Spectroscopic Explorer, or MUSE instrument, on the telescope captured a jet of material releasing from the young star. To discern whether a disk was present around the star, the team needed to measure how quickly dense gas moved around the star.

Newborn stars with these circumstellar disks had been observed by astronomers only in our Milky Way galaxy - until now. Observing these disks in other galaxies is very important because it tells us about how stars form in environments different from that of the Milky Way," McLeod added. The Large Magellanic Cloud is considered a satellite galaxy of the sprawling Milky Way, as is another galaxy called the Small Magellanic Cloud. The Large Magellanic Cloud has less dust than the Milky Way and a smaller content of what astronomers call metallic elements - those other than hydrogen and helium. McLeod expressed hope for detecting other circumstellar disks in the Large Magellanic Cloud and perhaps the further Small Magellanic Cloud.
