SDO’s EVE instrument uses sounding rockets for calibration. During roughly 15-minute flights, these suborbital rockets carry an EVE duplicate about 180 miles above Earth, where it records measurements to keep its twin instrument aboard SDO in tune. The next EVE calibration flight is scheduled to... Read More

New evidence from Hubble suggests that white dwarf stars could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters, which contain the... Read More

Is there weather on Mars? Short answer: yes! And just like on Earth it varies wildly. Now, thanks to the Mars Environmental Dynamics Analyzer, or MEDA instrument on NASA’s Perseverance Mars Rover, we're learning even more about Martian meteorology with daily weather reports. Over to José Antonio... Read More

The Earth is heating up. The effects of human-caused global climate change are becoming more and more apparent as we see more record-breaking heat waves, intense droughts, shifts in rainfall patterns and a rise in average temperatures. And these environmental changes touch every part of crop... Read More
