Rocky ‘Super-Earth’ Planet Discovered near Milky Way’s Old Star

TEHRAN (Press Shia Agency) – Scientists have discovered a huge 'super Earth' planet near one of the oldest stars in the galaxy. - Science news - The planet, called TOI-561b, is about 50 per cent larger than Earth, but requires less than half a day to orbit its star.This is partly due to the planet's close proximity to its star, which also results in blistering surface temperatures of over...

Astronomers Detect Giant Planet Orbiting Dead Star

Astronomers Detect Giant Planet Orbiting Dead Star

TEHRAN (Press Shia Agency) – Around 80 light-years from Earth lies the white dwarf WD 1856, a dead star that entered the final stages of its life around 6 billion years ago. - Science news - This slow death is typically quite lonely. In the process of dying, some stars will drastically expand, becoming a huge "red giant," like Betelgeuse, and engulfing any of the planets orbiting close by....

Planet Formation Theories Challenged by Surprisingly Dense Exoplanet

TEHRAN (Press Shia Agency) – New observations reveal a young exoplanet with unusually dense size and age, which is at odds with the predictions of leading planet formation theories. - Science news - New detailed observations with NSF's NOIRLab facilities reveal a young exoplanet, orbiting a young star in the Hyades cluster, that is unusually dense for its size and age. Weighing in at 25...

Venus Atmosphere Rotating 60 Times Faster than Planet Itself

TEHRAN (Press Shia) – A Venusian day, which is one full rotation of the planet, takes 243 Earth days, but researchers found out that its atmosphere rotates 60 times faster. - Science news - New research led by the Takeshi Horinouchi of Hokkaido University has revealed that the super-rotation of Venus' atmosphere is maintained near the equator by atmospheric tidal waves that have formed due...
