Surprisingly dense exoplanet challenges planet formation theories
Updated : 5 years, 7 months ago IST
Washington D.C.[USA], Aug 4 (ANI): 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 Earth-masses, and slightly smaller than Neptune, this exoplanet's

Could mini-Neptunes be irradiated ocean planets?
Updated : 5 years, 7 months ago IST
Washington D.C. [USA], July 20 (ANI): Many exoplanets known today are 'super-Earths,' with a radius 1.3 times that of Earth, and 'mini-Neptunes,' with 2.4 Earth radii. Mini-Neptunes, which are less dense, was long thought to be gas planets, made up of hydrogen and helium.

New explanation for Moon's strange asymmetry
Updated : 5 years, 8 months ago IST
Tokyo [Japan], June 22 (ANI): Earth's Moon has a 'near side' that is perpetually Earth-facing and a 'far side', which always faces away from Earth. The composition of the Moon's near side is oddly different from its far side, and scientists think they finally understand why.
