How life could help atmospheric tides slow a planet's rotation

Resonating oscillations of a planet's atmosphere caused by gravitational tides and heating from its star could prevent a planet's rotation from steadily slowing over time, according to new research by Caleb Scharf, who is ...

Hubble moving closer to normal science operations

NASA took great strides last week to press into service a Hubble Space Telescope backup gyroscope (gyro) that was incorrectly returning extremely high rotation rates. The backup gyro was turned on after the spacecraft entered ...

NASA uses Earth as laboratory to study distant worlds

The study of exoplanets—planets that lie outside our solar system—could help scientists answer big questions about our place in the universe, and whether life exists beyond Earth. But, these distant worlds are extremely ...

Researchers clarify dynamics of black hole rotational energy

Astrophysicists at MIPT have developed a model for testing a hypothesis about supermassive black holes at the centers of galaxies. The new model enables scientists to predict how much rotational energy a black hole loses ...

Musical sun reduces range of magnetic activity

A study of the sun using sound waves suggests that the layer in which the significant magnetic activity is located has grown thinner in recent years. Prof Yvonne Elsworth will present results at the National Astronomy Meeting ...

Image: Saturn and rings, 7 June 2017

The international Cassini spacecraft has completed half of the 22 dives between Saturn and its rings before concluding its mission on 15 September. Cassini has been exploring the Saturnian system for 13 years, and has been ...
