A near complete fossil rhinoceros has been found on an Arctic Canadian island, making it the most northerly rhino species ever.
Epiatheracerium itjilik [eet-jee-look] is described for the first time in a paper published in the journal Nature Ecology & Evolution. The “Arctic rhino” lived about 23 million years ago during the early Miocene epoch.
The new species was found in fossil-rich lake deposits in Haughton Crater on Devon Island which is part of the northern-most Canadian territory of Nunavut. Devon Island lies at a latitude of about 75°N, well within the Arctic Circle. It is also the largest uninhabited island in the world. (snip-MORE)

The largest low-frequency radio image of the Milky Way ever assembled has captured an unprecedented view of the galaxy, enabling astronomers to study the life stages of stars in new ways.
The data was captured by the Murchison Widefield Array (MWA) radio telescope at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory on Wajarri Yamaji Country in Western Australia.
“This low-frequency image allows us to unveil large astrophysical structures in our Galaxy that are difficult to image at higher frequencies,” says Associate Professor Natasha Hurley-Walker from the International Centre of Radio Astronomy Research (ICRAR). “No low-frequency radio image of the entire Southern Galactic Plane has been published before, making this an exciting milestone in astronomy.”
Hurley-Walker is principal investigator of one of the extensive surveys used to construct the image, the GaLactic and Extragalactic All-sky MWA (GLEAM) survey. (snip-MORE, and it’s interesting)
