Solar Eclipse Presents Rare Prospect To Examine Atmospheric Waves

Observing one entire solar eclipse—which swept in the continental U.S. during 2017—was not just enough for Jaxen Godfrey from MSU (Montana State University). Godfrey was a part of an MSGC’s (Montana Space Grant Consortium) team that used the unusual celestial event to carry out a research on gravity waves with three-quarters disturbances into the Earth’s envelope of gases that carry out weather patterns and impact wind turbine performance and wildfire behavior, among other things. Godfrey stated that basically, the gravity waves are similar to waves on water. The waves—which occur amid layers of the upper atmosphere—are comparatively common and can induce when winds flow across a mountain range.

But, an eclipse offers a special opportunity to analyze the phenomenon since the sudden obstacle of sunlight produces abrupt thermal transformations. She added, “The Moon’s shadow is similar to a boat passing through water.” During the 2017 eclipse, Godfrey with scholars from MSU and CDKC (Chief Dull Knife College) released 19 helium-packed weather balloons from Wyoming as a part of the MSGC’s Eclipse Ballooning Project. The balloons were equipped with sensors known as radiosondes to altitudes of 80,000 Feet. The palm-sized devices calculated pressure, temperature, and other variables in an attempt to analyze gravity waves throughout an eclipse for the first time.

On a related note, recently, a study stated that PSR J2055+3829 is a shadowing “black widow pulsar.” By carrying timing observations, researchers have revealed important understandings into the characteristics of the millisecond pulsar PSR J2055+3829. The research was published on e-print arXiv.org and stated that this entity is eclipsing “black widow” rotating neutron. The quickly rotating pulsars—having a rotation period of less than 30 Milliseconds—are known as MSPs (millisecond pulsars). It is believed that they are created in binary systems when a huge component at first is turned into a neutron star that is then worked up owing to accretion of matter from the secondary star.
