A new study using data from NASA’s Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has seen a 500-million-year decline, with an even steeper decline over the past 40 million years. Andromeda, a spiral galaxy comparable in size to our Milky Way, is close enough to be seen with the naked
Climate change has now become a problem for the entire solar system. On Friday, wildfires in Spain engulfed one of three observatories the U.S. National Aeronautics and Space Administration uses to connect with spacecraft, including Voyager 1, the James Webb Space Telescope and the recently completed Artemis mission around the Moon. Spain declared a wildfire
On July 3, one of NASA’s two Mars-bound ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft captured photographs of the Earth and Moon in visible and thermal infrared light. At the time, the spacecraft was 584,600 kilometers (363,250 mi) from Earth and 186,100 kilometers (115,600 mi) from the Moon, making the Moon appear relatively
Scientists on NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) mission have discovered a key piece of the puzzle in understanding certain types of auroras on Mars, discovering that they form similarly to terrestrial auroras.Results published Thursday in Nature Communications show that the same mechanism that circulates and catapults charged particles into Earth’s atmosphere is happening
Read this story in Spanish. here. NASA’s Juno mission has provided the first measurements of the temperature beneath the surface of Jupiter’s moon Io, revealing significant warming within the shallow subsurface of the solar system’s most volcanically active world. Data collected during two close flybys also show that most of Io’s surface is remarkably smooth
This map represents data captured by the Microwave Radiometer (MWR) aboard NASA’s Juno spacecraft, indicating the heat rising just below the surface of Jupiter’s moon Io. While infrared instruments measure the temperature of the moon’s surface, the MWR’s lower frequency microwave channels (0.6 and 1.25 gigahertz) can penetrate 6 to 20 feet (2 to 6
