NASA continues to study pulsars, 50 years after their chance discovery

These rotating 'lighthouse' neutron stars begin their lives as stars between about seven and 20 times the mass of our sun. Some are found to spin hundreds of times per second, faster than the blades of a household blender, and they possess enormously strong magnetic fields.

Sun's core rotates four times faster that its surface

more »
The sun's core rotates nearly four times faster than the sun's surface, an international team of astronomers reports. The most likely explanation is that this core rotation is left over from the period when the sun formed, some 4.6 billion years ago.

Perseid Meteors over Turkey

more »

The Perseid Meteor Shower, usually the best meteor shower of the year, will peak late next week. A person watching a clear sky from a dark location might see a bright meteor every minute. These meteors are actually specks of rock that have broken off Comet Swift-Tuttle and continued to orbit the Sun until they vaporize in Earth's atmosphere. The featured composite image shows a outburst of Perseids as they appeared over Turkey during last year's meteor shower. Enough meteors were captured to trace the shower's radiant back to the constellation of Perseus on the far left. The tail-end of the Perseids will still be going during the total solar eclipse on August 21, creating a rare opportunity for some lucky astrophotographers to image a Perseid meteor during the day.

Gravity waves detected in Sun’s interior reveal rapidly rotating core

Scientists using the ESA/NASA SOHO solar observatory have found long-sought gravity modes of seismic vibration that imply the Sun’s core is rotating four times faster than its surface.
