New Photoelectric Cells Turn Waste Heat Into Energy
In a new paper, researchers describe a new photoelectric cell that harvests heat energy, both from the solar panels and the surrounding air.
Using Moonlight to Calibrate Telescopes
The air-LUSI telescope has been taking more accurate measurements of the amount of moonlight in an effort to use the light to calibrate space telescopes.
Ganymede’s Auroral Footprint on Jupiter Traced
New measurements taken by NASA’s Juno spacecraft have found the link between the moon Ganymede and the planet Jupiter in the shape of an aurora.
Protoplanet Imaged During Formation
AB Aurigae b was directly imaged in joint operations between the Subaru and Hubble telescopes and provides evidence for the disk instability theory of planet formation.
SLS Tries to Have a Pre-Launch Test
NASA’s EGS office was supposed to conduct the Wet Dress Rehearsal for the Artemis 1 SLS rocket on April 4, but issues with a vent valve scrubbed the attempt.
Update: JWST Still Aligning Instruments
JWST is now aligned with all but one of its instruments — the Mid-Infrared Instruments, which will be aligned once it has cooled to operating temperatures.
Modeling Jupiter’s Origin Story
Using data from both the Galileo and Juno spacecraft missions, a new model of Jupiter’s formation explains the heavier elements in the gas giant’s atmosphere.
Looking at an Active System Up Close
Hubble captures an image of active galaxy NGC 7172, with a bright core and disk of material spiraling in toward the black hole’s event horizon.
Fourteen Eating Black Holes Share Web of Galaxies
Galaxy J1140-2629, the Spiderweb galaxy, sits at the center of a forming galaxy cluster, just 11.3 million light-years across with at least 14 active black holes.
Star Formation Dominated Earlier (but not Earliest) Universe
Sixty to ninety percent of early galaxies were experiencing extremely high levels of star formation, consistent with them being star-bursting galaxies.
