The first detailed image of Ultima Thule, showing two rounded lobes with a bright “neck” connecting them. It was taken at 5:01 Universal Time on Jan. 1, 2019, just 30 minutes before closest approach from a range of 18,000 miles (28,000 kilometers), with an original scale of 730 feet (140 meters) per pixel. Image […] 
Ultima Thule as seen by New Horizons on Christmas Eve. Still just a bright dot now, but soon will be seen up close for the first time ever. Image Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute NASA’s New Horizons spacecraft is now only two days away from a historic rendezvous with […] 
Artist’s concept of what the Kepler-1625b planet-moon system might look like. Image Credit: Dan Durda Exoplanets – planets orbiting other stars – have been found by the thousands now, with many more to come. But what about exomoons? So far there haven’t been any confirmed yet, and they are much more difficult to detect, […] 
Artist’s conception of the Kepler Space Telescope in space. Fuel is now running very low and the spacecraft has downlinked its latest science data to Earth. Image Credit: NASA/AP The end is nigh – that appears to be the case at least for NASA’s Kepler Space Telescope which is now running very low on […] 
This image is a combination of a JunoCam image with artist’s conception of lightning distribution in Juno’s northern hemisphere. Image Credit: NASA/JPL-Caltech/SwRI/JunoCam NASA’s Juno spacecraft has shown Jupiter in ways never seen before, not only sending back incredibly detailed images of the beautifully turbulent atmosphere, but also new data on what the giant planet […] 
“Self-portrait” of the Curiosity rover on Vera Rubin Ridge. Photo Credit: NASA/JPL-Caltech/MSSS Is there or has there ever been life on Mars? We still don’t know the answer for sure, but two new findings announced this morning by NASA during a live discussion provide more tantalizing clues. The new results come from the Curiosity […] 
Illustration of the Galileo probe at Europa in 1997, and how the plume disrupted the moon’s magnetic field. Image Credit: NASA/JPL-Caltech/Univ. of Michigan For decades, Jupiter’s moon Europa has fascinated scientists and the public alike after it was learned that a global water ocean lies beneath the icy crust. Could there be life on […] 
Artist’s conception of the proposed Europa lander, with sampling arm extended. Image Credit: NASA/JPL-Caltech For decades now, Europa has beckoned – this moon of Jupiter which is frozen on the outside but hides a global ocean on the inside – has so far only been visited by spacecraft during brief flybys. Scientists and the […] 
View from Curiosity of the Yellowknife Bay rock formation. Drilled samples here and elsewhere provided evidence that this region used to be at the bottom of a lake, but also that there are little or no carbonate mineral deposits, which should have been produced if the carbon dioxide atmosphere was thicker and warmer billions […] 
Artist’s depiction of OSIRIS-REx in orbit around Bennu. Currently, the spacecraft is searching for other Trojan asteroids near Earth. Image Credit: NASA Asteroids are some of the most ancient objects in the Solar System, relics left over from the time when the planets first started forming and evolving. For this reason, scientists are very […] |
