Massive Stars Make Their Mark in Hubble Image
This NASA/ESA Hubble Space Telescope image features a glittering blue dwarf galaxy called Markarian 178 (Mrk 178). The galaxy, which is substantially smaller than our own Milky Way, lies 13 million light-years away in the constellation Ursa Major (the Great Bear). Mrk 178 is one of more than 1,500 Markarian galaxies. These galaxies get their name from the Armenian astrophysicist Benjamin Markarian,…

NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean
A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data suggests a more complicated picture: Titan’s interior is more likely composed of ice, with layers of slush and small pockets of warm water that form near its rocky core. Led…

How Small Is Too Small? Volunteers Help NASA Test Lake Monitoring From Space
Volunteers participating in the Lake Observations by Citizen Scientists and Satellites (LOCSS) project have been collecting water level data in lakes since 2017. Now, the LOCSS team has used these data to examine the accuracy of water level measurements made from space. The results, published in GIScience & Remote Sensing, showed that modern satellites with special instruments called nadir altimeters can capture…
