Slowing down
The smallest celestial objects sometimes change their state of orbit or spin. The night sky has been long regarded as unchanging and even planets, the objects that move, are remarkably regular in their motion. We do know that the Earth has been gradually slowing in its rate of spin and gently closing in towards the …

New star may help decode Sun’s effect on Earth’s climate
Scientists have found a star that is almost identical to the Sun, except for the chemical composition, making it a ‘Rosetta Stone’ for the study of the solar body’s variability and effect on the Earth’s climate. The spots on the surface of the Sun come and go with an 11-year periodicity known as the solar …

Sun-like stars calm down after turbulent youth
Sun-like stars and their less massive cousins calm down surprisingly quickly after a turbulent youth, making the atmosphere more suitable for evolution of life, says a new study. The researchers used data from NASA’s Chandra X-ray Observatory and European Space Agency’s XMM-Newton to see how the X-ray brightness of stars similar to the Sun behaves …

Scientists to capture sunspot images during solar eclipse
During the upcoming total solar eclipse on August 21, a team of solar physicists are planning to capture high-resolution sunspots — the visible concentrations of magnetic fields on the Sun’s surface — at microwave radio wavelengths. Sunspots are the primary generator of solar flares, the sudden, powerful blasts of electromagnetic radiation and charged particles that …

Sun’s core rotates four times faster than its surface
An international team of astronomers has found that the Sun's core rotates nearly four times faster than the solar surface. The discovery was possible with European Space Agency (ESA) and NASA's Solar and Heliospheric Observatory, or SOHO, which helped the solar scientists find evidence of a type of seismic wave in our Sun. These low-frequency …

Distant comets more common than previously thought
Large comets that take more than 200 years to make one revolution around the Sun are more common in the universe than previously thought, a new study conducted by the US space agency NASA has said. Based on observations by the agency's WISE spacecraft, the study found that the number of long-period comets measuring at …
