Dynamics of ocean worlds likely controlled by their rotation

Discovering that many of the large moons in the outer solar system may host significant subsurface oceans of liquid water has been a key advance in planetary science. These moons represent some of the most promising habitats for life beyond Earth. But their hidden...

Crescent shaped crater in Northeast China breaks record as largest impact crater that formed in last 100,000 years

Scientists have confirmed that a circular mountain ridge in China's Heilongjiang Province is a crater made by an asteroid strike. The study published in the journal Meteoritics & Planetary Science. Scientists described their study of the crater and what they learned about it. Scientists noticed what...

Researchers discover what happens on the bright side of the moon

HSE University researchers have developed a mathematical model. It will explain the levitation of charged dust particles over the sunlit lunar surface for almost any latitude. The model takes into account the Earth's magnetotail, for the first time. Earth's magnetotail is a particular area...

Astronomers found new insights into the formation of brown dwarfs

Brown dwarfs are strange celestial bodies. They occupy a kind of intermediate position between stars and planets. Astrophysicists sometimes call them "failed stars". As they have insufficient mass to burn hydrogen in their cores. It is debated if the formation of brown dwarfs is a...

Scientists found a clue to the source of Earth’s water

The source of Earth's water has been a longstanding debate. Lawrence Livermore National Laboratory found an answer by looking at rocks from the moon. The Earth-moon system formed together from the impact of two large bodies. Their histories are very much linked. The moon lacks plate tectonics and weathering processes....

Scientists measure carbon ion loss from the atmosphere of Mars

Planetary scientists have developed evidence indicating that Mars was home to a relatively thick atmosphere. It hosted liquid water on its surface during the Noachian which was around 4 billion years ago. Significant climate change occurred since then. It results in the loss of...
