August 28–September 2 – The
solar storm of 1859, the largest geomagnetic solar storm on record, causes the
Northern lights aurora to be visible as far south as Cuba and knocks out
telegraph communication. This is also called the Carrington event,
Richard Carrington being the first known person to observe
solar flares, due to this storm. It is also the first major solar radiation storm to be recorded.[3]
Wilhelm Peters first describes the
guppy (fish Poecilia reticulata) from Venezuela.
Rudolf Virchow publishes Vorlesungen über Cellularpathologie in ihrer Begründung auf physiologischer und pathologischer Gewebelehre, a major textbook on
cellular pathology.[9]
