Their discovery, together with that of their seasonal waxing and waning (confirmed by modern observations), and a network of apparently artificial channels to distribute the meltwaters (observed in the late 19th century, but subsequently shown to be imaginary), led to the idea that Mars was populated by an advanced but dying civilisation.
Modern observations of the meteor shower also point to a recent breakup.
Modern observations have recorded sudden changes in the rotation rates of pulsars.
Indeed more modern observations with the COBE (Cosmic Background Explorer) satellite have shown this to be essentially a perfect dipole.
Modern observations show strong solar modulation of the blocking frequency and positioning during the 11-year solar cycles for the past 50 years, impacting substantially on UK winter temperatures22,23.
Paleoclimate data also provide an important role in balancing the interpretation of modern observations against the longer-term context in which ongoing ice sheet changes are occurring.
Modern observations of magnetic fields confirm basic ideas obtained earlier by A.B. Severny about field changes that occur over the course of a flare.
Accordingly, modern observations of sooty interstellar matter suggest, but do not prove, the likelihood of assembly rather than dispersal of protoplanetary matter.
Explores climate variability and change, focusing on the atmosphere and ocean, while building experience applying diagnostic analyses to a range of modern observations and models.
The evidence of modern observations, and the results of a molecular study, have confirmed the bird's status as a species.
Modern observations can reveal gas, dust, and stars in the optical, ultraviolet, and near-infrared from most observatories on Earth.
