Sulfur ‘spices’ alien atmospheres

IMAGE: Chao He and Sarah Hörst study exoplanet atmospheres at The Johns Hopkins University. view more  Credit: Will Kirk/Johns Hopkins University They say variety is the spice of life, and now new discoveries from Johns Hopkins researchers suggest that a certain elemental 'variety'--sulfur--is indeed a 'spice' that can perhaps point to signs of life. These findings from the researchers' lab simulations reveal that sulfur can significantly…

NASA finds Tropical Storm Irondro’s heavy rainfall displaced

IMAGE: The GPM core satellite passed over Tropical Storm Irondro on Apr. 6 at 2:26 a.m. EDT (0626 UTC). Heaviest rainfall (orange), located southeast of the center, was falling at a... view more  Credit: NASA/JAXA/NRL NASA analyzed Tropical Storm Irondro's rainfall and found heaviest rainfall was being pushed far southeast of the center because of strong wind shear. NASA has the unique capability of peering under…

What makes Saturn’s atmosphere so hot

The upper layers in the atmospheres of gas giants -- Saturn, Jupiter, Uranus and Neptune -- are hot, just like Earth's. But unlike Earth, the Sun is too far from these outer planets to account for the high temperatures. Their heat source has been one of the great mysteries of planetary science. New analysis of data from NASA's Cassini spacecraft finds a viable explanation for…

Mysteries of Uranus’ oddities explained by Japanese astronomers

IMAGE: Uranus is uniquely tipped over among the planets in our Solar System. Uranus' moons and rings are also orientated this way, suggesting they formed during a cataclysmic impact which tipped... view more  Credit: Lawrence Sromovsky, University of Wisconsin-Madison/W.W. Keck Observatory/NASA The ice giant Uranus' unusual attributes have long puzzled scientists. All of the planets in our Solar System revolve around the Sun in the same…

NASA-NOAA satellite catches Tropical Cyclone Harold develop near Solomon Islands

NASA-NOAA's Suomi NPP satellite passed over the Southern Pacific Ocean and provided forecasters with a visible image of newly formed Tropical Cyclone Harold. Harold formed near the Solomon Islands and now threatens Vanuatu, which has already issued some warnings. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a visible image of Tropical Cyclone Harold on April 3, 2020. The VIIRS image…
