Often seen on Earth, the effect consists of concentric, colorful rings of light, and it occurs when light reflects off clouds made of a uniform substance.
Washington DC (UPI) Dec 22, 2023 - SpaceX returned more than 30 research payloads, many of which were vital life science investigations, from the ISS National Laboratory to Earth Friday.
Planetary scientists have discovered exoplanets in the star HIP 104045, 175 light years from Earth. The system of this star, which is close to the Sun in age and properties, includes at least two gas giants.
Climate change is expanding Antarctica s sea ice, according to a scientific study in the journal Nature Geoscience.
The paradoxical phenomenon is thought to be caused by relatively cold plumes of fresh water derived from melting beneath the Antarctic ice shelves.
This melt water has a relatively low density, so it accumulates in the top layer of the ocean.
The cool surface waters then re-freeze more easily during Autumn and Winter.
This explains the observed peak in sea ice during these seasons, a team from the Royal Netherlands Meteorological Institute (KNMI) in De Bilt says in its
.
Climate scientists have been intrigued by observations that Antarctic sea ice shows a small but statistically significant expansion of about 1.9% per decade since 1985, while sea ice in the Arctic
