Warming global climate is changing the vegetation structure of forests in the far north. It’s a trend that will continue at least through the end of this century, according to NASA researchers. The change in forest structure could absorb more of the greenhouse gas carbon dioxide (CO2) from the atmosphere, or increase permafrost thawing, resulting […]
As part of ESA/Hubble’s 35th anniversary celebrations, the European Space Agency (ESA) shared new images that revisited stunning, previously released Hubble targets with the addition of the latest Hubble data and new processing techniques. ESA/Hubble released new images of NGC 346, the Sombrero Galaxy, and the Eagle Nebula earlier in the month. Now they are revisiting the star cluster Messier 72 […]
The first two rockets launched from Poker Flat Research Range north of Fairbanks on Tuesday, March 25, with one taking a route similar to Saturday’s rocket and the other flying farther north to eject colorful vapor tracers over the Arctic Ocean above Utqiagvik and Kaktovik. The mission, titled Auroral Waves Excited by Substorm Onset Magnetic […]
Two NASA sounding rockets launched from Poker Flat Research Range north of Fairbanks early Tuesday morning in a mission aimed at learning more about how the aurora affects the upper atmosphere. The two rockets performed as expected, releasing tracer payloads widely visible across central and northern Alaska. Completion of the study awaits launch of a […]
