Global warming and melting glaciers have redefined the ‘polar wander’ or the drifting of the Earth’s axis, finds a study published in Geophysical Research Letters.
Astrophysicists using the Gemini telescope have spotted the first ‘blow-away’ galaxy.
Blown away galaxy
Recently blown away galaxy has been spotted using the Gemini telescope
The Gemini Observatory is an astronomical observatory consisting of two 8.1-metre telescopes, Gemini North and Gemini South, which are located at two separate sites in Hawaii and Chile, respectively.
The twin Gemini telescopes provide almost complete coverage of both the northern and southern skies.
It has been reported that Hydrogen clouds have been stripped off exposing high-energy light.
Polar Wandering
The study of polar wandering began in the early 20th century.
Polar wandering, the migration of the magnetic poles over Earth’s surface through geologic time.
Austrian priest and geologist Damian Kreichgauer and German scientists Wladimir Köppen and Alfred Wegener, proposed the first paths of geomagnetic North Pole migration.
On the time scale of polar wandering, geomagnetic reversals (polarity reversals of the geomagnetic field) are relatively frequent.
That polar-wandering curves for different continents (which show the paths of a magnetic pole with respect to a given continent) do not agree was one of the first important evidences for continental drift (the large-scale movements of continents and ocean basins relative to one another over geologic time).
