Hubble Space Telescope Detects Protective Shield Defending a Pair of Dwarf Galaxies

Scientists have used spectroscopic observations of ultraviolet light from quasars to detect and map the Magellanic Corona, a diffuse halo of hot, supercharged gas surrounding the Small and Large Magellanic Clouds. Shown in purple, the corona stretches more than 100,000 light-years from the main mass of stars, gas, and dust that make up the Magellanic … Read more

NASA’s Juno Spacecraft Captures Closest View of Jupiter’s Icy Moon Europa in 22 Years

On September 29, 2022, NASA’s Juno spacecraft captured the complex, ice-covered surface of Jupiter’s moon Europa during a close flyby. Credit: NASA/JPL-Caltech/SWRI/MSSS Observations from the Juno spacecraft’s close pass of the icy moon provided the first close-up in over two decades of this ocean world, resulting in remarkable imagery and unique science. Earth has now … Read more

New evidence for liquid water on Mars

Scientists have uncovered further evidence that liquid water exists beneath the ice cap at the southern pole of Mars and it may mean that the planet is geothermally active. In 2018, the European Mars Express orbiter found that the surface of the ice cap covering the south pole of March dips and rises, suggesting liquid … Read more

SpaceX offers to help raise the altitude of NASA’s Hubble space telescope

Elon Musk could help to save Hubble, after NASA revealed it will study the possibility of running a private astronaut mission with SpaceX to extend the iconic telescope’s lifespan. The 32-year-old observatory is slowly losing altitude and if nothing is done to re-boost it then Hubble will eventually fall into the Earth’s atmosphere and burn … Read more

NASA’s SOFIA Boeing 747 Has Taken Its Last Ever Flight

On Wednesday, September 28, at around 20:45 local time (03:18 UTC of Thursday), the Boeing 747SPregistration N747NA, owned by NASA and modified to carry a reflecting telescope for the Stratospheric Observatory for Infrared Astronomy (SOFIA), operated its last flight ever. The flight lasted seven hours and 58 minutes, departing from Palmdale Airport (PMD), and flying … Read more

Scientists Identify the Source of the Planet Ceres’ Unexpected Geological Activity

Dwarf planet Ceres is shown in these false-color renderings, which highlight differences in surface materials. Images from NASA’s Dawn spacecraft were used to create a movie of Ceres rotating, followed by a flyover view of Occator Crater, home of Ceres’ brightest area. Credit: NASA/JPL Modeling reveals how Ceres powers unexpected geologic activity. According to Scott … Read more

NASA’s Juno spacecraft captures extraordinarily detailed images of Jupiter’s moon Europa

NASA‘s Juno spacecraft has taken its first picture of Jupiter‘s moon Europa — capturing the ice-encrusted surface in extraordinary detail. The image is the closest look at Europa that any spacecraft has provided in more than 20 years, when the US space agency’s Galileo came within 218 miles (351 km) of the surface in January … Read more

Webb and Hubble Space Telescopes Capture Detailed Views of DART Asteroid Impact

These images, Hubble on the left and Webb on the right, show observations of the Didymos-Dimorphos system several hours after NASA’s Double Asteroid Redirection Test (DART) intentionally impacted the moonlet asteroid. It was the world’s first test of the kinetic impact technique using a spacecraft to deflect an asteroid by modifying its orbit. Both Webb … Read more
