RHESSI Stories
Earth planning date: Friday, Feb. 7, 2025 We are continuing our merry way alongside “Texoli” butte, heading toward the boxworks feature in the distance, our next major waypoint. This is a series of large-scale ridges, which appear from orbital data…
Measuring water loss from space This study showed that the International Space Station’s ECOSTRESS instrument estimates of evapotranspiration (transfer of water to the atmosphere from Earth’s surface and plants) are comparable to ground-based reference values. This finding suggests space measurements…
The elevation changes may seem small — amounting to fractions of inches per year — but they can increase or decrease local flood risk, wave exposure, and saltwater intrusion. Tracking and predicting sea level rise involves more than measuring the…
Astronomers may have discovered a scrawny star bolting through the middle of our galaxy with a planet in tow. If confirmed, the pair sets a new record for the fastest-moving exoplanet system, nearly double our solar system’s speed through the…
FjordPhyto is a collective effort where travelers on tour expedition vessels in Antarctica help scientists at Scripps Institution of Oceanography and Universidad Nacional de La Plata study phytoplankton. Now project leader Dr. Allison Cusick has a Ph.D.! . Dr. Cusick…
Light pollution has long troubled astronomers, who generally shy away from deep sky observing under full Moon skies. The natural light from a bright Moon floods the sky and hides views of the Milky Way, dim galaxies and nebula, and…
NASA and its partners recently tested an aircraft guidance system that could help planes maintain a precise course even while flying at high speeds up to 500 mph. The instrument is Soxnav, the culmination of more than 30 years of…
A supernova and its host galaxy are the subject of this NASA/ESA Hubble Space Telescope image. The galaxy in question is LEDA 132905 in the constellation Sculptor. Even at more than 400 million light-years away, LEDA 132905’s spiral structure is…
Earth planning date: Wednesday, Feb. 5, 2025 Overnight before planning today, Mars reached a solar longitude of 40 degrees. The solar longitude is how we like to measure where we are in a Mars year. Each year starts at 0…
The Moon will pass into Earth’s shadow and appear to turn red on the night of March 13 or early in the morning on March 14, depending on time zone. Here’s what you need to know about the total lunar…
