Hubble Finds Medusa in the Sky

From NASA Oct. 24, 2019 Hubble Finds Medusa in the Sky Often referred to by its somewhat drier New General Catalogue designation of NGC 4194, this was not always one entity, but two. An early galaxy consumed a smaller gas-rich system, throwing out streams of stars and dust into space. These streams, seen rising from…

Hubble Spots Stunning Spiral Galaxy

From NASA May 3, 2019 Few of the universe’s residents are as iconic as the spiral galaxy. These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust, creating truly awesome scenes — especially when viewed through a telescope such as the…

Unexpected rain on sun links two solar mysteries

NASA/Goddard Space Flight Center For five months in mid 2017, Emily Mason did the same thing every day. Arriving to her office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, she sat at her desk, opened up her computer, and stared at images of the Sun — all day, every day. “I probably looked…

Enormous Aquifer Discovered Under Greenland Ice Sheet

From NASA, I had to laugh at this statement: The water in the aquifer has the potential to raise global sea level by 0.016 inches (0.4 mm). That’s assuming it can get out sometime in the distant future. Greenland’s topography under the ice is bowl shaped. =================================== Buried underneath compacted snow and ice in Greenland…

NASA to do summer aerial melt watch for Greenland

NASA Begins Airborne Campaign to Map Greenland Ice Sheet Summer Melt For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt. NASA’s C-130 research aircraft flew from the Wallops Flight Facility in Wallops…

Glacier in Antarctica does what glaciers do

From NASA, who has moved up from “Manhattans” to quarter states as a scale comparison unit: Antarctic Glacier Calves Iceberg One-Fourth Size of Rhode Island This week a European Earth-observing satellite confirmed that a large iceberg broke off of Pine Island Glacier, one of Antarctica’s largest and fastest moving ice streams. The rift that led…

Mysterious 'electron stash' found hidden among Van Allen belts

You’d think the science on the Van Allen Radiation belts was long ago considered “settled science”. Nope. And yet, while we discover new things like this, some insist we fully understand all aspects of the workings of Earth’s climate. Instruments detect never-before-seen phenomenon in Earth’s Magnetosphere The belts are a pair of donut shaped zones…
