Hey guys!! I’m pretty sure the majority of you are from mainland America so you don’t have the opportunity to see the northern lights, like, ever. Tonight you can!! Possibly. There’s a pretty severe geomagnetic storm going on and it’ll be hitting pretty darn south and a whole crap ton of people that have never seen northern lights, might be able to see them!!

I highly encourage everyone in the red/yellow lines to try to take a look tonight! I grew up with northern lights literally in my backyard and they’re just such a pleasant sight to see. According to the weather network it’ll go down as far as Alabama!

Sea Turtles’ Secret GPS: Researchers Uncover How Sea Turtles Learn Locations Using Earth's Magnetic Field - UNC News

A new study at UNC-Chapel Hill provides the first evidence that sea turtles can learn & remember the unique magnetic signatures of the Earth

"A new study from researchers at the University of North Carolina at Chapel Hill provides the first empirical evidence that loggerhead sea turtles can learn and remember the unique magnetic signatures of different geographic regions. This discovery offers new insights into how turtles and other migratory animals navigate vast distances to reach specific foraging and breeding grounds. The findings, published in the journal Nature, also suggest that sea turtles possess two distinct magnetic senses that function differently to detect the Earth’s magnetic field."

"Through controlled experiments, the research team demonstrated that loggerhead turtles can indeed learn and remember the magnetic fields of areas where they receive food. This ability suggests that turtles use learned magnetic information to navigate back to foraging areas, helping explain their remarkable navigational accuracy over long distances. More broadly, these findings could apply to a wide range of migratory animals that rely on magnetic cues for navigation. 

“The ability to distinguish among magnetic fields of different geographic areas likely explains how many animals – not just sea turtles – can navigate long distances to specific locations,” said Ken Lohmann, a professor of biology at UNC-Chapel Hill. 

The research also delves into the underlying mechanisms of magnetic sensing. The results indicate that turtles’ magnetic map sense and magnetic compass sense rely on different ways of detecting magnetic fields, suggesting the presence of two distinct magnetic senses in these animals. This discovery provides a major advancement in the broader scientific understanding of how animals perceive and use the Earth’s magnetic field."

"The study’s interdisciplinary nature highlights the importance of collaboration across scientific fields. Notably, the specialized antenna system built for this research closely resembles technology used for separate research, demonstrating the broad applications of electromagnetic principles."

Northern lights linked to North Sea whale strandings

Large solar storms, responsible for the northern lights, may have played a role in the strandings of 29 sperm whales in the North Sea early in 2016.

A new study says these geomagnetic disruptions may have confused the whales' ability to navigate, diverting them into the shallow waters.

Trapped and lost, the whales died on European beaches, attempting to escape.

The research has been published recently in the International Journal of Astrobiology.

@Regrann from @onealrodriguez - The sun and moon revolving around a flat earth. 🤔 This is a clock being used to explain the concept. #geomagnetism The branch of geology concerned with the magnetic properties of the earth. ---- #Geocentrism is the belief that the sun, the planets and all the stars revolve around the Earth. - #heliocentrism vs #geocentrism The answer took a while for astronomers to figure out, leading to a debate between what is known as the geocentric (Earth-centered) model and the heliocentric (Sun-centered model). ... The Earth was in the center of it all (geocentric), with these planets revolving around it. ------- Truth fears no investigation. What yall think?
