NASA’s DART: science fiction has become reality

The destruction of a multimillion-dollar spacecraft is not normally something to celebrate. But the crashing of NASA’s Double Asteroid Redirection Test (DART) spacecraft into an asteroid is an important exception. On Monday, NASA announced that DART had collided with Dimorphos, a small body just 160 metres in diameter, which orbits a larger asteroid called Didymos, … 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

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

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 Mars dips and rises, suggesting liquid … Read more

NASA experts left baffled after spotting bizarre object stuck to foot of Mars helicopter | Science | News

NASA is investigating a piece of debris that has appeared on the foot of the Ingenuity helicopter during its latest flight through the skies of Mars. The small piece of “foreign object debris” was spotted by the Mars helicopter’s navigation camera (Navcam) on its latest flight — having not been present during the craft’s previous short … Read more

Potential first traces of the universe’s earliest stars – HeritageDaily

Astronomers may have discovered the ancient chemical remains of the first stars to light up the Universe. Using an innovative analysis of a distant quasar observed by the 8.1-meter Gemini North telescope on Hawai‘i, operated by NSF’s NOIRLab, the scientists found an unusual ratio of elements that, they argue, could only come from the debris … 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 747SP, registration 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 … Read more

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

These images, Hubble on 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 and … Read more
