Hubble peeks at stellar treats

Looking its best ever is the star cluster NGC 2203, here imaged by the NASA/ESA Hubble Space Telescope. Aside from its dazzling good looks, this cluster of stars contains lots of astronomical treats that have helped astronomers ...

The rotation of Venus

Venus is covered in a thick layer of clouds, one reason that it appears so bright in the sky. Ancient astronomers had a good idea of what (since Copernicus) we know as its orbital period; the modern measurement is that Venus ...

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 ...
