In: Technology

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have uncovered an unprecedented richness of small gas-phase hydrocarbons — such as benzene, triacetylene, diacetylene, acetylene, methane and methyl radical — in the deeply obscured nucleus of the ultra-luminous infrared galaxy IRAS 07251-0248, which is located in the constellation of Monoceros. Hydrocarbons play a key role inContinue Reading

Jupiter is Smaller and More ‘Squashed’ than Previously Believed, New Juno Data Reveal

On:
In: Technology

Using high-precision radio-occultation measurements from NASA’s Juno mission and incorporating the effects of zonal winds, planetary scientists derived Jupiter’s shape with an order-of-magnitude reduction in uncertainty, finding polar, equatorial and mean radii smaller than previous estimates made with NASA’s Pioneer and Voyager missions. The post Jupiter is Smaller and MoreContinue Reading
